Application and advantages of UWB technology in automotive glass

By integrating the UWB module into the car glass, only four anchor points are needed at most to achieve keyless entry and liveness detection at the same time, which can reduce costs and increase efficiency. Compared with the front and rear bumper solutions, it can alleviate the signal shielding problem to a certain extent and make positioning more accurate. For example, based on automobile perception and intelligent technology, Fuyao Group has launched a smart pillar product with glass as the exterior panel, which can be integrated with the car body glass. The product integrates intelligent driving camera system, structured light camera perception system, keyless entry system, biometric system and other functions. For digital key scenarios, it can provide NFC, BLE, UWB, micro switch, touch switch, biometrics and other solutions. The smart pillar product has been mass-produced and installed on the Zhiji L7 model.
