| 摘 要： | 商用车驾驶过程中,车速是仪表向驾驶员提供信息中较为重要的信息,车速指示的准确性、可靠性、响应性直接影响车辆运行的安全和驾驶体验,以及巡航等控制功能的品质。本文介绍一种基于VCU(整车控制器,Vehicle Control Unit)的车速处理方法,VCU同时采集车速传感器脉冲信号和接受CAN总线的ABS轮速信号,经过综合计算处理后输出车速至CAN总线供仪表显示及其它控制功能使用,试验表明此种方法处理的车速具有分辨率高、误差小、可靠性高、后期市场维护便捷等优点。

| Abstract: | The vehicle speed is an important information to the driver when a truck is running. The accuracy,reliability,responsiveness of the vehicle speed indicator are closely related to the vehicle safety and the quality of cruise control function. This paper introduces a method based on VCU(Vehicle Control Unit). The VCU receives both the pulse signal of hall sensor and the ABS wheel speed signal from CAN bus, after comprehensive calculation processing,VCU outputs the speed valueto the CAN bus for IC display or other control units. The test result shows that this method of speed processing is with high resolution,accuracy,stability,and easy for customer service. |
