In order to demonstrate technology Audi used VR helmet and giant touch screen
In the past few years, the development of automotive technology is changing with each passing day. These cars were once autonomous cars and were not associated with a vast world. Now that it's not the same, the new car is a wearable computer with 4 seats, a large number of sensors, screens, and wireless connections to data. Some of these technologies are purely digital tricks. There is no practical use. Playing music via Android Auto or CarPlay is no more advanced than Bluetooth. Despite this, there are still some technologies (such as advanced driver assistance systems) that will become stepping stones and help us enter the automotive world.
For drivers, these security systems are difficult to "see" when they are not really needed. There are still some technologies that are complicated and new. Because of this, automakers need to explain the technology and explain to customers that they only pay for it if they understand it. Interpretation is a difficult task. Audi spent a lot of thought on this matter. Recently, it brought us to Munich to understand its own solutions.
Since 2013, Audi has established a partnership with Oculus, which is why VR has played an important role in Audi's planning. For example, Audi has set up a virtual showroom. We have seen some demo samples, one is a static demo sample, supported by Oculus, and the other is a mobile sample, supported by HTC Vive. Oculus equipment seems to be more mature, it is aimed at the European market, Europe's car specification is more complex than the United States.
The virtual showroom allows users to explore the car. The cars are rendered and the details are quite rich; it includes 5 million polygons. In fact, the virtual car was originally only pure CAD data from the design department, if it had been rendered, there were 60 million polygons. Audi's device is powered by two Nvidia M6000 graphics cards with a frame rate of 90fps and a very low latency of only 20ms. Audi is not willing to take risks. It does not want potential customers to feel dazed and sick.
The Vive device is still under development and it will take a long time for the device to appear in Audi's flagship venue. The user does not have to use a static viewing angle and the head can be in any direction. Through the engine room of the R8 sports car, the V10 engine will appear in front of your eyes, you can look into a single cylinder or cooling room. Audi also digitized an Auto Union car for users to explore.
Audi's other VR demo products are a bit surprising. There is a pavilion on the side of the airport apron in Munich, where Audi presents advanced driver assistance systems (ADAS) such as “Pre sense cityâ€. If pedestrians are found on the road, the car will brake automatically. It can guarantee the driver, Pedestrian safety. We can experience these features in the Virtual Training Car.
The ADAS function detects the target through a camera on the front of the car, covering a range of 328 feet (100 meters). If the car's speed does not exceed 40 kilometers per hour, the Pre sense city system orders the car to stop and will not be affected when the car is moving at a higher speed.
On the surface, Audi's virtual training car is an A4 sedan, just a few more antennas. When the boot of the car is opened, the luggage space is occupied by electronic equipment. Two cooling fans are placed on the armrest in the center of the rear seat. The elastic head cushion was removed and replaced with a light bar aimed at the back of the driver. Compared with the ordinary A4 car, the virtual training car has a screen that is placed directly in front of the front passengers. Of course, the training car also has an Oculus helmet for the driver.
The driving area is about 2,000 feet (600 meters) long, and the width is about 1000 feet (300 meters). The surrounding area is full of GPS tags. In this way, various GPS systems can clearly determine the position of the car to an accuracy of 0.8 inches (20 mm). ). If you don't wear a VR helmet, you only see asphalt pavement. Put on a helmet and you will enter the virtual town, but you are still sitting on the A4. The interior of the car is also rendered. It's quite fine. Looking down at the wheel and actually moving is really weird because the hand is not on the steering wheel and the foot is not on the pedal.
The car started to go through the slow-skiing track and then entered the traffic carousel. When the car returned, a virtual pedestrian suddenly walked out of the sidewalk into the driveway, at which point the Presense City system was activated. The virtual car's display will issue a virtual warning message, and soon the seat belt will be pre-tensioned and the emergency brake system will be activated.
In order to demonstrate modern security systems, Audi's method of choice is "elegant". We have also seen some demos before, and the technical content is very low. For example, let people wear a wedding dress standing in front of the car. Audi technology can also replace other technologies such as Ford's VIRRTEX simulator.
In the VR environment and the physical A4 car, Audi must first integrate, because the car's electronic "brain" needs sensors to obtain the data provided by the virtual world before they can start an emergency subroutine. Audi used virtual training vehicles to train more than 5,000 sales staff worldwide. Now Audi is expanding the scope of application of the system to demonstrate technologies other than "Pre sense city".
The virtual training vehicle has a disadvantage and is not suitable for facing the customer's experience. It is precisely because of this that Audi developed the Virtual Engineering Terminal. The so-called virtual engineering terminal is a large touch screen desktop, 55 inches in size, 1.4 meters high on the desk, and a monitor on the wall. A variety of Audi cars can be placed on the touch screen, it can show how different systems (such as traffic congestion assistance systems, matrix LED headlights) are running on the road.
