For a long time, the automatic driving was in a state of being visible and intangible. However, with the development of technology, more and more manufacturers are beginning to use autonomous driving technology in cars.
Google Although it is a non-automotive manufacturer, Google announced the development of self-driving cars in October 2010, and in May 2012 won the first auto-driving vehicle license in the United States.
Google's complete set of Google Fleet autopilot equipment includes a laser rangefinder placed on the roof to accurately and accurately map 3D topographic maps within 200 meters of the perimeter and upload them to the onboard computer. To put it bluntly, Google’s driverless car “sees” other vehicles through the above-mentioned equipment, mainly relies on massive map data for navigation support, and is not strictly self-driving.
Volvo At present, the autopilot technology of most manufacturers is similar, that is, using the camera, radar, infrared, etc. to achieve the positioning of the vehicle, so as to achieve the purpose of controlling the vehicle. But Volvo gave Volvo a completely different gameplay -- the magnet.
Safe and reliable high-precision positioning system has always been a major problem in the development of autonomous driving. Existing positioning technologies such as G PS and visual images have limitations under certain conditions, while magnetic field roads can completely get rid of the adverse effects of obstacles and bad weather.
Volvo researchers built a 100-meter test road on the outskirts of Gothenburg, Sweden, and buried a series of 40 x 15 mm circular ferrite magnets 200 m below the road surface. The self-driving vehicle that participated in the test was equipped with multiple magnetic field sensors, and then guided along the road under the guidance of the magnet.
On March 11, Volvo Car Group announced today that it has successfully completed the magnetic field road research project. Jonas Ekmark, head of the safety and technical team of Volvo Car Group, said, “The magnetic field on the road surface is like forming an invisible rail. The positioning error is less than one decimeter. We have tested different speeds and the test results are exciting. ”
Volkswagen Volkswagen Group is developing the TAP short-time automatic driving technology, which belongs to the category of semi-automatic driving technology and bridges the gap between the driving assistance system (DrivingA ssistanceSystem) and the future full-authority automatic driving technology. Vehicles equipped with TAP technology are under driver supervision and can travel semi-automatically on the road at 80 mph (130 km/h).
In June 2013, the Israeli company ObileyeVionion called the Audi A 7 to provide a cheap driverless system. With the addition of hundreds of dollars of equipment, it can handle one-way highways, accelerate and stop by signal lights, and said it will be launched in summer. Traffic jam assistant function product.
Mercedes-Benz According to the official promotion of Mercedes-Benz, Mercedes-Benz S-Class sedan can basically achieve automatic driving if conditions such as law permit.
Mercedes-Benz claims that in 2021, Mercedes-Benz will launch a self-driving car before the next-generation S-class enters the market. The new-generation S-Class has been equipped with an adaptive cruise system that automatically maintains a certain distance from the front car and automatically turns to ensure The car is in the driveway (the hand needs to be on the steering wheel). The S-Class with an automatic driving system allows the driver to completely remove his hand from the steering wheel. The lab has implemented this feature.
BMW At the CES Consumer Electronics Show in Las Vegas in January, BMW officially released its own autonomous driving technology. BMW has already launched autonomous driving technology called ConnectedD rive Connect, and BMW's recently released High-Analyted Driving can be seen as a more advanced version of ConnectedD rive Connect.
BMW named the autopilot R&D project “UR:BAN”, which focuses on three directions: cognitive assistance, networked transportation systems, and human factors in transportation. However, BMW's autonomous driving research and development is more focused on the development of driver assistance systems, not the role of the car to replace the driver.
Ford Ford also put a lot of effort into autonomous driving. An automated driving system developed in collaboration with the University of Michigan (T heU niversity of Michigan) and the State Agricultural Insurance Company (StateFarm) is equipped with a test vehicle called the Ford FusionH ybrid.
Ford's autopilot system uses four light detection sensors for object recognition, enabling 2.5 million scans per second. It is easier than the popular and versatile autopilot system and requires no driver intervention.
It is reported that Ford will launch autonomous cars almost around 2025.
Nissan Nissan Leaf received the first public road test license plate in Japan in 2013 for public road testing. Nissan claims that it will take 8-10 years to gradually infiltrate this type of technology into its own models after launching autonomous vehicles from 2020.
Nissan's current autopilot test is to load a laser scanner, a panoramic image monitoring system, and advanced artificial intelligence and transmissions in the windmill, which allows the car to be completed on the highway without a map. , change lanes and avoid driving collisions.
In addition, according to the technical staff of the Nissan manufacturer, Nissan's technology can identify all current traffic signs, no longer have to worry about matching or replacing new traffic signs.
