Audi Q4 e-tron augmented HUD transmits driving information to the windshield

Must read


Although it might not be as fast as his cousin GTThe upcoming Audi Q4 e-tron EV compact crossover will have a few new tricks that the sedan doesn’t. Specifically, the Q4 will be equipped with an augmented reality head-up display (HUD), although optional, capable of displaying critical driving data directly in the driver’s field of vision.

HUDs aren’t really new to automobiles, or even electric vehicles. For my part, I was a huge fan of the HUD pop-up on the Kia niro ev as of 2019. However, the Q4’s HUD is more than just a piece of clear plastic mounted on the steering column – it’s displayed in the windshield itself. The HUD consists of two sections: a static status section that displays basic information such as the current vehicle speed and traffic signs, and an active augmented reality (AR) section. In the AR section, features like the direction arrows generated by the navigation system will be superimposed in the driver’s field of vision (pretty much where they should be in real life), appearing to float up to 10 meters away. in front of the vehicle at 60 FPS and covering approximately a 70 inch diagonal portion of the front windshield. The status section, on the other hand, will appear to be just 10 feet from the driver’s position.


To generate these images, the Q4 relies on what Audi calls its Image Generation Unit (PGU), located in the driver’s dashboard. “A particularly bright LCD screen directs the light beams it generates onto two level mirrors, and special optical components separate the parts for near and far field areas,” the company said in a press release Tuesday. “The level mirrors direct the beams onto a large electrically adjustable concave mirror. From there they reach the windshield, which reflects them in what is called the eye box, and therefore on the driver’s eyes.

To prevent the augmented images from shaking, jumping, or losing out of sync with the real-world situation around them, the Q4 uses an AR Creator (essentially a software-based modular processing unit) to constantly predict where to find it. objects around the vehicle and how fast. their positions change during the fractions of a second necessary to collect, process and display the information gleaned by the various sensors of the vehicle on the HUD. This prevents the AR image from shaking and shaking when driving on the street.



Interestingly, the AR HUD works even though the Q4 is operating in adaptive cruise. Although the vehicle stays in the center of the lane, the HUD will still provide the driver with relevant information. For example, if the Q4 sees that it is approaching a lane marker and the driver has not yet engaged the turn signal, the vehicle will activate its lane departure warning system and superimpose a straight red line. on the actual lane marker.

The HUD isn’t Audi’s only new tech toy. Like the GT, the Q4 comes with modern displays such as the 10.25-inch dashboard, which comes standard. It replaces the mechanical meters and dials of yesteryear with a “power meter” that sums up all the relevant information the driver might need, from the vehicle’s horsepower to the amount of charge remaining in the Q4’s 82 kWh battery. Drivers will also have the choice of a standard 10.1-inch (1540 x 720) MMI touchscreen infotainment display that handles the majority of vehicle cabin functionality or they can upgrade to an 11.6-inch version. (1764 x 824) that Audi touts. like its largest touchscreen to date. The larger screen will be optional and should be available by the end of the year.



And, since playing with the touchscreens while driving is a great way to end up with your car riding across the central division of the freeway, the Q4 e-tron will offer voice control. Just say “Hey Audi” to activate it and ask your question as you would any other driver. But no, unfortunately, he does not have a Gray Baby.
