文中介绍了一种由防止接近控制模块(ACC)和电动安全带模块(MSB)组成的汽车防追尾碰撞系统。此系统的信息传输、交换处理由以ECU为核心的汽车快速响应控制局域网(F-CAN)来完成。通过车头雷达采集车辆在行驶过程中的相对车速、相对车间距等参数后,由F-CAN系统传输给ECU进行数据处理,然后返回执行指令给相应机械以防止汽车追尾,保障驾驶员和乘员的安全。文中详细分析了组成防追尾碰撞控制系统的防止接近控制模块和电动安全带模块及制动模块的工作原理。
This paper introduces a vehicle collision avoidance collision avoidance system consisting of ACC (ACC) and E-belt module (MSB). The information transmission and exchange of this system are completed by the Automotive Fast Response Control Local Area Network (F-CAN) with the core of ECU. After collecting the relative speed, relative distance between vehicles and other parameters during the driving process, the vehicle radar transmits the data to the ECU for data processing, and then returns the execution instructions to the corresponding machinery to prevent the vehicle from rear-end and ensure the driver’s and crew’s Safety. The paper analyzes in detail the working principle of anti-collision control system, anti-collision control module, electric belt module and brake module.
