The potential of low-power Bluetooth technology to enhance the user experience of automotive access systems is limitless. Users can unlock their vehicles using their smartphone keys as they approach their cars. The car can automatically adapt to user preference settings, such as mirror, seat, steering wheel, and head-up display positions, based on custom digital profiles. With the low-energy Bluetooth-based car access system, the car can also use various secure ranging and positioning technologies to position authorized phones inside the car, adding an extra layer of security before unlocking the car door and starting the car. Additionally, users can create digital keys for friends and family, and temporary digital keys for valet parking, making car sharing more convenient.
This solution is based on the development of Bluetooth 5.0 chip and technology using TI CC2640R2F, CC2640R2F-Q1, CC2642R-Q1 vehicle-grade chips, on Android 8.0 and above or iOS 5.0 and above. The smartphone is built-in with BLE master-slave mode which can senselessly identify and position with the BLE slave device and BLE scanning antenna arranged on the car body. This function can be realized without opening the APP under the premise that the user completes user registration and vehicle ownership verification and turns on the phone's Bluetooth function.
