摘要
汽车防碰撞预警系统对减少交通事故,保障车辆行驶安全,提高道路通行率有着重要的意义。以飞思卡尔MC9S12XS128MAL为控制核心的汽车防碰撞预警系统测试平台,能够实时采集车辆的行驶速度、加速度以及相邻两车之间的距离,然后根据驾驶员驾驶状态判断出车辆的安全状态,最后利用TFT液晶显示屏实时显示出来,当车辆行驶危险时能够进行声光报警。
It has important significance for the vehicle collision warning system to reduce traffic accidents, ensure the safety of vehicle, and improve the traffic capacity. The test platform of the vehicle collision warning system, which was controlled by the Freescale＇s MC9S 12XS128MAL, could real-time acquisite the vehicle＇s speed, acceleration and the distance between cars, then judge the vehicle＇s safety state according to the drivers＂ driving condition. At last, it could real-time display the information, and make visual alarm when the vehicle had danger.
