摘　　要：目前减小后视镜视野盲区是提高驾驶员行车安全的重要措施。利用无线通信技术设计了汽车后视镜控制系统,发射端采用方向盘转角传感器采集方向盘的转角数据,用NRF24L01模块实时发送数据;接收端采用NRF24L01模块对数据进行无线接收,利用STM32进行数据处理后,控制后视镜控制端的电机转动,使后视镜自适应地调整到最佳位置。经过测试分析后得出,采用无线通信技术的方式实现了汽车后视镜的自适应调整,减小了驾驶员行车过程中后视镜视野盲区。The reduction of rearview mirror′s blind area is an important measure to improve the traffic safety of driver.Therefore,an automobile rearview mirror control system was designed by means of wireless communication technology.The steering wheel angle sensor is used in the transmitting terminal to acquire the steering wheel angle data.The NRF24L01module is used to transmit the data in real time.The NRF24L01module is adopted in the receiving terminal to perform the wireless receiving for the data.The STM32is employed to process the wheel angle data to control the motor of the rearview mirror′s control termi-nal,and adjust the rearview mirror to the best position.The test analysis results show that the method based on wireless commu-nication technology can realize the adaptive adjustment of the automobile rearview mirror,and reduce the blind area of the rear-view mirror in the driving process of driver.
