底盘测功机一般有2个传感器,即车速传感器和力传感器。在底盘测功机标定时,通常是对这2个传感器进行标定,把两者的误差控制在一定范围内,从而保证驱动轮输出功率检测的精度。在底盘测功机的标定方法中,车速传感器的标定通常比较规范和准确,而在力传感器的标定中,存在的问题比较多,使驱动轮驱动力和输出功率的检测值严重失真,因而导致错误的试 Chassis dynamometer generally has 2 sensors, namely speed sensor and force sensor. In the chassis dynamometer calibration, usually the two sensors are calibrated to control the error between the two within a certain range, so as to ensure the drive wheel output power detection accuracy. In the calibration method of the chassis dynamometer, the calibration of the vehicle speed sensor is usually more standardized and accurate. However, in the calibration of the force sensor, there are many problems that seriously degrade the detection values ​​of the driving force and the output power of the driving wheel, Wrong trial
