The invention discloses a vehicle running speed testing system, method and device and belongs to the field of vehicle testing. Firstly, the testing device is connected with a to-be-tested vehicle, so when the to-be-tested vehicle runs, an auxiliary wheel is vertically contacted with the ground, the vehicle can drive the auxiliary wheel to run together when running, and since the auxiliary wheel is smaller than the vehicle in size and is more convenient to measure, an encoder is connected with the auxiliary wheel to obtain the instantaneous angular velocity of the auxiliary wheel; then a data acquisition device acquires instantaneous angular velocity of the encoder, and finally the processing display device calculates instantaneous linear velocity of vehicle driving according to the acquired data. According to the method, the driving speed of the to-be-measured vehicle can be simply and conveniently obtained.

    本发明公开了本申请技术方案提供一种车辆行驶车速测试系统、方法及装置,属于车辆测试领域;首先测试装置与待测车辆连接,使待测车辆行驶时,辅助轮竖直接触地面,这样车辆行驶时会带动辅助轮一同行驶,由于辅助轮相比车辆体积较小,更方便测量,因此采用编码器与辅助轮连接,获取辅助轮的瞬时角速度,然后数据采集装置采集编码器的瞬时角速度,最终处理显示装置根据采集的数据计算得到车辆行驶的瞬时线速度。本申请方案能够简单方便的得到待测车辆的行驶车速。
