what a driver-less car? Google's driverless car.

Recently, a British Lutz PAthfinder officially open the road test unmanned news sparked many fans and technology enthusiasts curious, as a British government-led drone pilot project Lutz PAthfinder in Greenwich, Bristol, Kashmir Dayton Keynes and Coventry actual road test, including the park area equipped visitors tour the park, pick up passengers at the railway station and other tests. In fact, in addition to Lutz PAthfinder, current unmanned vehicle development can be described as being in a state of contending blowout.

Traditional auto manufacturers:

Mention unmanned, perhaps a lot of people think of first is Google 's driverless project, but in fact unmanned process, the efforts to be more traditional car manufacturers. In these traditional automobile manufacturers seems driverless car technology is the inevitable outcome of an iterative update, from 1939 Oldsmobile introduced the first automatic transmission systems to 1958 Chrysler cruise control system allows the driver no longer always pay attention to driving speed; then in 1997 part of the Toyota car is equipped with radar-based adaptive cruise control, which automatically maintain a safe driving distance from the vehicle in front; and finally to Dan Ammann, president of General Motors in 2020 to open an unmanned commercial tradition Although there is no Google car manufacturers such "step" Great Leap Forward-style, but with nearly a century of automotive accumulation process to achieve the gradual evolution towards unmanned technology.

Mercedes-Benz as the inventor of the automobile on the unmanned car also did not lag behind. In September 2013, Mercedes-Benz aspects of the conduct of the hundreds of kilometers of testing driverless cars, more historical significance to commemorate the automobile inventor Karl Benz's contribution, this time from unmanned test also selected The first year Benz car tests go Mannheim to Pforzheim, Germany road. Mercedes-Benz S-Class cars in the past different driver assistance systems, road test this time is truly driverless, the most important contributor to the length of the radar and the camera, with each other, they were aware of the surrounding environment.

In the 2015 CES, Mercedes-Benz once again show results in unmanned areas. Its F 015 Luxury in Motion unmanned automatic driving concept car won a lot of venues around the attention of passers-by. In the unmanned route through the built-in realization of 3D map data and GPS with independent planning, the stereo camera body is equipped with radar and ultrasonic sensors that can sense the surrounding environment, and then back to the onboard computer for processing, and then the next step instruction back to the mechanical transmission. In addition to the travel system because Extended Sense system involvement, this concept car also with surrounding vehicles and pedestrians to communicate, for example, when passers-by waved, it can stop and yield.

When referring to unmanned technology, Google believes Radar (Radar), Lane Keeping System (Lane-keeping), laser ranging system (LIDAR), infrared camera (Infrared Camera), stereo (Stereo Vision), GPS / inertial navigation system, the wheel angle encoder (Wheel Encoder) is the core component. Because there is no set steering wheel, accelerator, brake and other traditional mechanical devices, Google unmanned vehicle is thoroughly autopilot, the principle is the scanner on the roof beam 64 emitted laser beam, constantly probing the surrounding environment; then measured by the system at the bottom of the vehicle acceleration, angular velocity and other data in the three directions; plus the surrounding real car camera captured a summary to the on-board computer to achieve the perception and analysis of the physical environment.

At the same time, the PLA Academy of Military Transportation unmanned tests are carried out, and has entered the third generation of the product development process. As the Academy of Military Transportation independent research and development of unmanned vehicles, code-named "lion of the 3rd" car main tools include five radars, three cameras, a satellite navigation system, relying on these configurations, it can achieve adjacent lanes to overtake, with the car running, self-change lanes, etc., and has achieved measured Beijing station road toll station to Tianjin Dongli Lake toll station, a top speed of 115 km / h, the entire 114 km, takes 85 minutes, passing 33 times.

In other manufacturers, BYD and Singapore laboratory studies reached an agreement to jointly develop unmanned projects; Geely rely on Volvo's safety technology is also buried unmanned test; Chinese Academy of Sciences, Guangzhou Automobile also work together to carry out unmanned vehicle test; SAIC chose AVICHINA jointly carry out the relevant tests, we can say the country is currently in the research and development of unmanned speed hot pursuit of international respect has been the pace.
