“If you’re going 30 miles an hour it takes you a little less than a second to look down at your speedometer and come back up and at that speed you go 46 feet in that time frame, which is the length of a semi,” said Bill George, NSG Pilkington business planning director, as he explained the company’s new technology. “So you get the idea that if you glance down for a fraction of a second and you glance back up and something happens in front of you, you need to be aware.”
Nippon Sheet Glass (NSG) Group announced that its new windshield Head-Up Display (HUD) technology will be featured in General Motors’ all-new full-size SUVs: the 2021 Chevrolet Tahoe and Suburban, 2021 GMC Yukon/Yukon XL, and 2021 Cadillac Escalade/Escalade ESV models.
The 15-inch multi-color HUD is focused on driver safety. According to George, there’s an overriding trend when it comes to HUD – “the need is really in the name Heads Up,” he said. He noted that more vehicle manufacturers are looking into this technology on their windshields in an effort to keep vehicle driver’s eyes on the road.
“The thought process is if we can keep people’s eye’s up, we can keep them aware of what’s going on in front of them,” said George.
The previous HUD displays were about the size of a notecard, according to George, but the new HUD displays are slightly bigger than a regular sheet of paper. They’re also starting to combine HUD technology with ADAS systems, which gives you information on if a car is in front of you is slowing down or speeding up and it connects with your GPS, according to George.
The Next Step
“All of this is a step to the next generation of HUD – augmented reality,” said George. “The HUD becomes much larger and more advanced and what’s happening is vehicles are going to start communicating with each other. This bridge is going to allow your windshield to be augmented.”
If these types of systems are going to be interacting with ADAS it also means the HUD will need to be calibrated when the windshield is calibrated, according to George.
