摘　　要：设计提出了一种里程防误计算系统,在系统中安装两个霍尔传感器,在齿圈随车轮转动时,两个传感器同时检测并输出脉冲信号。用于消除车辆停泊在霍尔传感器检测临界位置时产生的不规则脉冲信号,避免错误计算,提高车辆行驶里程计算的准确性。In this paper, a mileage error-proof calculation system is proposed. Two Hall sensors are installed in the system. When the gear ring rotates with the wheel, the two sensors simultaneously detect and output the pulse signal. It is used to eliminate the irregular impulse signal produced by the Hall sensor when the vehicle is parked at the critical position, avoid the wrong calculation and improve the accuracy of vehicle mileage calculation.
