The unmanned "Ten essential system Digimaser 3 Secret

Driverless not a simple project, you need to control a variety of  Digimaser 3  complex electronic equipment mutual collaboration in order to achieve the goal. Ten technical elements essential for the unmanned technology.

Vehicle location technology. Commonly used techniques include magnetic navigation and visual navigation can accurately identify the location of the vehicle.

Vehicle control technologies. Mainly includes a speed control and direction control. The most commonly used method is a classic intelligent PID algorithm, fuzzy PID, neural network PID for example.

Vehicle stability system. ESP, electronic parking brake, as well as various types of electronic stability system, to prevent loss of control of the vehicle.

Automatic parking system. The  obd2 tool  system, the vehicle by radar and other sensing systems, the car automatically stops into parking spaces.

Radar system. Sensing means mounted in the bumper next to issue a warning when the detected what appears in the automotive blind spot.

Lane keeping system. The sensors can be mounted on the windshield to identify a lane marking. Car accident left lane, the steering wheel through the transient vibration or interfere with driving reminder.

Collision-avoidance system. Half of the sensor is placed in the position of the front bumper through the sensor to monitor the distance to the vehicle in front, automatic emergency brake.

Infrared camera equipment. Camera installed on the windshield to monitor infrared signal, and is very suitable for the night observation roadside pedestrian security.

Stereo vision system. Of two camera mounted on the windshield of real-time 3D image of the road ahead, potential hazards, such as pedestrians, bicycles, and is expected to move towards.

The solenoid control system. Control elm327   corresponding parts, and to replace the manual operation by the electromagnetic principle.

Oil overfill cause vehicle obd2 tool breakdown

Some owners believe car maintenance, is nothing  obd2 tool  more than an oil change, check the oil line, so maintenance is not necessary to the 4S shop or repair shop to buy their own barrels of oil, would like to increase the number to increase the number of. Recently have the owners of oil plus overfilled and cause the car fails. In this regard, the automotive repair professionals said that the oil is not added more the better.

Case: oil fill cause oil leakage

Nancheng Seriburi it comes to the things of their vehicles, and a look of regret. Seriburi in December last year to buy a new car, self-drive home in the New Year, the first maintenance is 5000 km or three months, Mr. Zhu would like nothing more than a change of oil, maintenance, and do not need to 4S shop to do the maintenance, and the first free maintenance, and decided to go to use in the second maintenance. Therefore, Mr. Zhu in his hometown to buy oil, home village and a small repair shop to replace results Seriburi oil to buy more, not willing to lose, he commanded the people try to fill the repair shop. Results during the Spring Festival in the car, the car began the oil leaking and burning oil.

Seriburi way worried about the car  elm327   back to Dongguan, immediately took the car to the 4S shop for check-ups. Upon inspection of the 4S shop told Mr. Zhu said, the car is such a phenomenon, mainly because before Mr. Zhu will be the oil plus too full causes car engine carbon deposits more now, combustion chamber burning oil is too full .

The viewpoint: Oil Cadogan will hurt car

In this regard, the automotive repair professional people Shiwei master said, many owners total oil to fill a good thing. In fact, oil Cadogan, but it hurts the car. Car to keep bearing journal benign lubrication, need oil to act as the smooth agent effect, otherwise it will aggravate the wear and tear and even lead to burning the ZWZ incidents likely to cause agencies running resistance is increased. However, the oil  BMW GT1  Cadogan, will be likely to cause the oil flying, may result in the combustion chamber burning oil to produce coke.

The paint routine maintenance and obd2 touch-up painting Detailed

Automotive paints are generally baked paint. Depot  obd2  inside the frame, the car shell welding is completed (and sometimes hand-patched), the next process is painting. In general, the first (high-end car first using phosphated anti-corrosion technology) primer. Light car shell immersed in syrup-like paint tank, remove the drying primer; then fed into a dust-free workshop, spray on the top coat with electrostatic painting process. And then dried with a temperature of about 200 degrees. Elegant point, there will be another layer of varnish. In this way, the paint process and you're done. General topcoat the several: Pu Tongqi; metal paint; pearlescent paint. Pu Tongqi Needless to say, resin, pigments and additives. Metallic paint more aluminum powder; future looks bright so complete. The pearlescent paint it, adding cloud masterbatch. Mica is a thin piece of something, reflective directional, there will be a colorful effect. Metallic paint and varnish layers, the car's paint looks very bright, very beautiful. Color, white is undoubtedly the cheapest. For example, a world-class brand red pigment is probably more expensive than the world-class brand titanium dioxide 25 times; while the amount of titanium dioxide white paint is about five times the red pigment. Therefore, the cost of red paint color than white paint five times. This is why some domestic cars color varieties so little: a simple, low cost.
No matter what the color of the paint, the pigment will fade in sun. In fact, not only the paint, any color stuff in the sun may fade. In this case, how the paint inside plus additives is very important. Such as light stabilizers, such as antioxidants. Unfortunately, the good additives expensive expensive. In many cases, additives This   obd2 tool  paint gives the feeling of how good or bad decision. One would certainly think that some sort of two years, began to appear significantly fade the paint than five years, bright as new paint. But in fact, the paint does not fade. Many times, the factory is more concern: fade evenly. Try not to make the different parts of the car color difference.
The new car arrived, is to paint the most easily damaged. The car wash is not careful, the paint will be injured. In fact, even to hold things in the production line, when there are things to damage the paint.
Generally small scratches, paint surface has scars, scars whitened. That is painted surfaces shaving. There is no necessary touch-up painting. Light, playing with sand wax or multi-hit several times wax. Weight, to be a polished it can be had. Serious, able to see the color of the underlying primer (in many cases, the primer is a dark color). So, Please take another look at the site of the scar. Generally, bumpers, mirrors and some car wheel eyebrow these parts, engineering plastics. Will not rust. Actually, I have a big   Renault CAN Clip  problem addition unsightly. Fill up painting they do not matter. Other (torture), it would have to touch-up painting, otherwise, even if it is a small breakage, steel will start to rust that time, even up painting it is difficult anti-embroidered.

East Insight is cheaper than the Prius test drive lexia 3

As the earliest introduction of the domestic hybrid,  lexia 3   the Toyota Prius dominate in this area has been a dominant day, however, it seems almost head. The Guangzhou auto show, Honda has brought a whole new Insight, priced at 209,800, the cheapest Prius is even lower than 20,000, your heart?

Insight and Prius compared to body size, and power level to account for less than any cheaper, but the fuel economy of similar ability, but also the most critical issue is the price, because the structure of the power system is relatively simple than the latter also precisely because of this, the ultimate realization of the   Launch X431 GX3    price advantage. , In the U.S. market, Insight is in sales beyond the Prius, that this set of practices in the country able to copy the success of this?

 The Prius body size 4485x1745x1510mm, two cars put together, Insight will be significantly smaller. Insight looks a bit like the Civic, but the wheelbase and body width data seems more like the extended version of the Fit. 1435mm ride height is lower than the regular models, but in fact, it did not cause too much interior space.

Honda fans first saw Insight may think it is a bit like with the Civic, but Honda is not playful Volkswagen sets her face go the personalized route models especially like the Insight this respect Zhang distinctive face. Large angle of the front, the design of the hatchback half and the second half of the fastback style, which seems to have become the unspoken rules of the new energy vehicles, Wal-blue Chevrolet, Toyota Prius are invariably comparable design . Obviously, this design can reduce the drag is a consensus in the industry.
 Insight uses the same tire size and fit, but the brand is not the Hankook, but a the Michelin XM1 series, focus on durability as obd2 tool      well as energy-saving, coupled with a narrow width, tire grip performance from the force in general.

Changan Rui Cheng impressive lexia 3

Bring an independent brand, you can think of the  lexia 3  word, what is it? Inexpensive, rough, plagiarism? These words should be the first impression of most people own brand models, but the last couple of years, there are a lot of own brand models began to walk in high-end line, such as the great Wall C50, Chery E5 Fengshen A60, Dorsett EC8 and so on, although the sales is not very good, but we also see from these models on the determination of the independent brand "re-hatting".

Many brands have competed to launch high-end models, Chang'an is also about to launch a high-end model - Rui Cheng, edit fortunate detailed real shot the first time on the new car, and my colleagues will be in the near future simple test drive article of the launch of the new car. The front face with the Accord very sort of similar, especially the air intake grille, chrome number just to be different, but a closer look, but also Qiaochu taste of the sort of Camry, but the design is fairly decent, "plagiarism" also    Launch X431 GX3    considered clever. Rui Cheng car there headlight cleaning function grade on this comparison, the other is the front there are two radar probe. Look at the side, almost all the lines are exactly the same as the Lexus LS 460L side look at the taillight style is exactly the same.

Order to the clear expression Rui Cheng car in the end how I deliberately its data with the Accord, Camry, Passat together for comparison, although the size is quite does not mean the car and that several B-Class is a level, get down to business, so that a comparison can be found in the car is very large indeed.

The rear design is very upright, moving with Yat almost four parking sensor plus a reverse image, the car and then a big, parking is not a problem. Carried through vehicle lines extended to the taillights at the other side and rear chrome strip just connected. The Rui Cheng is the SPORT 270 series, Dunlop tires,   obd2 tool front and rear tire size: 215/55 R17. Ten turbine-like wheels shape is very exaggerated, and also added some chrome elements, shining very hyun.

Direct injection gasoline obd2 tool engine technology

The total number of car owners that certain brands obd2 tool  have direct injection technology is very advanced, even many people Bong artifact With it leading the pack. With that way of thinking, or as a benchmark for the first product to other brands, other models foot, it only shows a frog in a well. In fact, direct injection technology from birth has been nearly 90 years, many depots during this time to explore the feasibility and practicality. To this end, we particularize this article for a review of the course of development of the direct injection, especially after the popularity of the EFI engine, from the beginning of the 1990s, it is how to walk
With the increasing intensification of the contradictions of the development of the automotive industry and energy shortages, how in the pursuit of high-power, low-carbon environment to maximize the full potential of the engine at the same time respond to the tide, even if it is a multi-point fuel injection technology can not meet the requirements of the people . The saying goes, there is a demand market, so just gave birth to the emergence of new technologies, more precise injection technology was born, that is, direct injection technology.
For internal combustion engines, direct injection (GDI) can also be referred to as called spark ignition direct injection (SIDI) fuel  OBD2 Scan Tool stratified injection (FSI), it has been widely used in today's two-stroke or four-stroke gasoline engine. Practice distinct from the fuel nozzle is placed on the intake manifold, the direct injection is the fuel injector is placed within the cylinder, through the high-pressure fuel pump, the fuel injection into the combustion chamber, so atomization more meticulous, more uniformly mixed with the air, to ensure a more smooth and efficient combustion of the fuel.  

The direct injection to achieve a more accurate control of the proportion of the mixed gas, to eliminate the disadvantages of direct injection in the cylinder outside. In the same time, the position of the nozzle, the spray shape, the intake air quantity and the intake air pressure, as well as the combustion chamber of different designs can change the ratio of the mixed hydrocarbon, in order to  http://lexia3.blogcu.com/5-elements-to-improve-autocom-cdp-pro-car-audio-sound-quality/12996289 achieve homogeneous combustion or stratified combustion. Direct injection stratified combustion based on lean-burn technology to improve fuel efficiency to ensure high output while reducing fuel consumption. In an era of environmental protection, low-emission, high-power, direct injection technology represents an important technological innovation of traditional gasoline.

How to distinguish sedan four-wheel obd2 tool technology

With the addition of cars the listing of Zexi, equipment four-wheel obd2 tool drive system a choice. Technological development we are not allowed to say that, who knows the day sedan four-wheel drive and turbo, like sweeping the globe? After all, the winning vehicles from the 1982 World Rally Championship are full-time four-wheel drive car. So we come to discuss the technology to discuss the four-wheel drive cars.First, the center differentialIf your brother does not know the "differential" This stuff that need to go to make up classes, this article does not go into this. The role of the central differential with the differential is the same reason, the differential is in order to allow both sides of the wheels to rotate at different speeds, and the central differential is in order to allow two anteroposterior axis to operate at different speeds.The four-wheel-drive sedan is necessarily a center differential (off-road vehicles may not necessarily). The center differential is the hub of the four-wheel drive system, the role of the engine power distribution to the front and rear axles, similar to the "waist" waist good kidney good legs and feet, not to say okay, is the same reason. Waist Yi Yao water bucket waist, waistline, and so on and so  Auto Diagnostic Tool forth. Center differential are many ministries the same features, and even the center differential that his title has become less and less used. For as long as it is assigned to the core components of the front and rear axle torque, we still can not understand it as a center differential differential.1, full-time or timely. For full-time or timely, of course we can not listen to the name to determine, but this is well understood. Full-time is characterized by at any moment are allocated on four wheels, and timely are generally in some cases (usually occurs wheelspin) connected to four-wheel drive system.2, the transfer of power of the front and rear axle ratio range is large enough. Typical example Zexi front-wheel drive, the rear axle most torque distribution of 50%, the Acura rear axle can get up to 70 percent of the torque distribution, allocation of torque front and rear axle of the Audi Quattro system can be 15% - varied between 85% and Tiguan 4motion system torque distribution between 0-50%.3, the response speed. Since the structure and principle of the same, the response speed of each of the central differential is not the same. Called the response rate is very professional and that, in fact, the young man he thought of as a loss of balance, fast response can not fall immediately adjust the center of gravity, slow reaction will be to shoot directly. The car's four-wheel drive system on the reaction rate is higher than the cross-country. The sedan is the moment things got out of control at high speeds, the response speed is fast enough, you can get out of control impending four control,  lexia 3 v47  rather than waiting out of control (slip) and then attempt to control.
Audi Quattro is the famous center differential Torsen differential. Since using the principles of the purely mechanical force distribution, like differential is an innate physical properties, and therefore no reaction time can be automatically assigned the torque to the front and rear wheels. Audi is also often in the hall on the hanging cited thought proud of gecko logo reasons.

Development of lexia 3 radio remote control driving technology

Since the automobile was born the day people imagine lexia 3 whether to let them run up security without intervention ongoing technical exploration, engineering research and development staff also A Hundred Years of automotive development and manufacturing, and finally in the 20th century a remote driving of prototype cars. After the birth of a variety of prototype cars, the technology is still always makes unmanned technology market-oriented exploration. August 2012, with the the BYD speed Rui listed on the world's first remote control technology to achieve driverless car market officially born.World Expo held in 1939, the American industrial designer Norman Bell Geddes exhibited a ground-breaking models in their own future urban theme exhibition. The car relies on the electromagnetic coil embedded in the pavement to provide power-driven, motorists radio remote control can be used to manipulate them. The entire car R & D has been GM's assistance, the car also became a historical a driverless technology car.Driverless car technologyNarrowly divided unmanned technology is the the vehicle completely rely on their own ability to travel, free from human intervention and manipulation in the whole process of moving. However, in view of the current level of technology, this unmanned technology is also exploring stage, a more limited range of practical Launch X431 GX3 applications. In broader terms, as long as the vehicles during the people in the car, or no direct control mechanism (steering wheel, accelerator and brake pedal by the vehicle itself) control vehicle technology can be called unmanned technology. This is one of the most widely used remote driving skills.RC driving skillsThe remotely piloted technology is nothing new, small remote control cars, large construction machinery or military UAV use this technology. View from the spread of the signal of the carrier is generally divided into radio remote control, infrared remote control and ultrasonic remote control. Household appliances remote control used in our daily lives is the infrared remote control, this technology uses infrared signal transmission, has the advantages of simple structure, convenient, low-cost production. But its remote shorter distances, and not be able to remote control signals pass through a barrier defects, and also vulnerable to interference problems when the sun is strong and more prominent, infrared remote is close remote, especially  obd2 tool indoor remote preferred.
