According to foreign media reports, the two automakers Lexus and Audi recently showed their latest self-driving technology to the public at CES 2013 in Las Vegas, USA. For this news, the outside world may think that Lexus and Audi will adopt a similar "autonomous driving strategy", but in fact, the two companies have a very different understanding of the concept of "autonomous driving".
Lexus
The main purpose of the Lexus driverless strategy is based on safety considerations. At present, the company's luxury model LS is equipped with the world's leading "pre-crash system" (pre-crash system). Therefore, Lexus believes that the main purpose of the autonomous driving concept is to help car owners prevent possible human driving errors. Lexus is now building a new driving system based on this philosophy of safety first, and firmly believes that drivers can use this to drive cars on the road more safely.
"From a conceptual point of view, our unmanned driving program is completely different from Audi, because we believe that the so-called 'automatic driving' is not equivalent to 'unmanned driving'." Said a Lexus company staff.
In general, Lexus is hoping to build the automatic driving system into an auxiliary system for drivers while driving, which can help them better control and protect their vehicles.
For example, Lexus recently demonstrated a self-driving car based on the LS600h model, and installed a large number of radar, photography and navigation equipment on the body. In addition, the car also uses an advanced technology called "Intelligent Transmission System", which allows the car to communicate with other vehicles on the road, can plan a travel plan, and coordinate the ownership of each car. The highway network system of the lane is networked.

At this CES exhibition, the German car manufacturer Audi demonstrated its latest "Piloted Driving" system. The system allows the driver to concentrate on other tasks while driving, while the vehicle can automatically drive through congested areas. If the user wants to actively change lanes and cancel the automatic driving of the system, only need to lightly pedal or turn the steering wheel actively.
Audi's understanding of the concept of "autonomous driving" is: "Under normal circumstances, consumers buy Audi cars mainly to pursue driving pleasure. But if the owner encounters traffic jams on the highway, the so-called" driving fun "will disappear.
Therefore, we developed this 'Piloted Driving' driving system for traffic congestion. If the owner of the car encounters a traffic jam and the speed of the vehicle remains below 35 miles per hour, the driver can activate the system by pressing a button on the steering wheel. After the system intervenes, the driver can leave the steering wheel with both hands, and the feet do not have to continue to rest on the pedals. "
It is reported that Audi plans to promote this technology in the next 10 years, and if the final product is really as we saw at CES, the current full-time driver may face the danger of being laid off.
It is worth mentioning that Audi also demonstrated its latest automatic parking system at CES. The owner only needs to open the application on the smartphone and click a button. This Audi A7 equipped with automatic parking system can be used from The parking lot automatically opened in front of the owner.
In the demonstration, the car drove out of the parking space of the Mandarin Oriental Hotel, and after a difficult journey of about 150 feet, it finally stopped steadily at the door of the hotel. In fact, this process is more complicated than people think, because it is navigated by a laser scanner installed in the parking lot, and the car and the laser scanner are connected by WiFi.
Only in this way, this driverless car can accurately park in the garage and avoid obstacles during driving. That is to say, the entire demonstration process of this driverless car is largely completed by the laser scanner in the parking lot. Therefore, this demonstration is not possible in every place, only in those places where navigation equipment is installed, unmanned driving can be achieved.
In all fairness, the autonomous driving technology of Audi and Lexus is not good or bad, because the innovation of both in the autonomous driving system will help future drivers to drive cars more comfortably and safely.
