Design of vehicle control system based on bluetooth low energy smartphone platform

A vehicle control system based on Bluetooth 4.0 on smartphone platform is designed in this paper. The system uses Apple iPhone4s and TI CC2540 which supports BLE (Bluetooth Low Energy) specification to realize short-range communications. On the one hand, vehicle BCM (Body Control Module) with CC2540 collects the car information by CAN in real-time. On the other hand, the smartphone connects CC2540 to control the vehicle and to display the information on smartphone interface using BLE technology. The Apple iPhone4s' application is on the base of X-code4.5 development platform with iOS6. The experiments show that the control system has a good performance and a broad prospect of application in short-range communication.
