摘要
提出了利用MRE转速传感器并结合软件解算的车速测量系统,该系统利用SJA1000 CAN控制器及CTM1050T CAN收发器有效实现了车速信息经CAN总线向中央控制ECU的传输。仿真分析实验(或车架实验)证明,车速测量系统能够准确完成高、低速车速的测量。
In this paper,The speed collection system using MRE speed sensor combined with software is put forward.The system realizes the information transmission to ECU by CAN bus using SJA1000CAN controller and CTM1050TCAN transceiver.It is proved that the speed measurement system can complete the accurate collection of speed by the simulation experiment.
