The EV model of Audi GT, the Audi Q4 e-Tron, has some nice features. One of the most impressive features is the augmented HUD beams on the windshield of the car. Instead of installing the heads-up display or HUD on the car’s steering, it is set up within the car’s windshield for a better display option.
Due to the augmented HUD beams, the driver will get all the data for critical driving. What we liked about the HUD beams is that it has two sections. One section is the static status responsible for informing the vehicle’s speed, traffic signs, and much more. The other section is the AR or the augmented section displays signs like indicators or turning arrows in the driver’s line of sight. In simple language, you would be able to view the indicators on the windshield itself. The AR will superimpose it on the windshield.
While the AR will be superimposing the signs, it won’t make them visible in the driver’s direct vision line. The image will be floating 10 meters in front of the vehicle and will cover around 70-inches of the windshield’s diagonal portion. Moreover, the driver would be able to see the vehicles in front of the car and the arrows simultaneously.
The picture generation unit or PGU of the car Generates all the images. This particular unit is located in the instrument cluster of the car. The PGU uses two large concave mirrors that generate the images. “The level mirrors direct the beams onto a large concave mirror that can be adjusted electrically. From there, they reach windshield, which reflects them into what is known as the eyebox, and thus onto the driver’s eye,” explained the company in the press release.
Audi has even created an AR creator to prevent the images from jumping or jittering when the driver is viewing them. This AR creator is a software-based processing unit that can predict the objects near the vehicle. The AR creator can even collect data on how fast these objects are changing their position, which further helps in creating clear AR images. The PGU and the AR creator go hand in hand and make sure that the driver gets to see clear images in his/her line of vision.
Another interesting thing about the HUD in the Q4 e-Tron is that it provides the driver with all the information. One example is that if there is a lane marker and the driver has not yet turned on the indicators, the car will activate the driver’s warning system. The Q4 is going to be the most advanced EV in the market. Though the car’s speed might not match with the GT, the features will make it more advanced and safer to drive.
