Abstract

The invention discloses a braking test device and a method for testing the dynamic braking performance of an autonomous vehicle. The braking test device comprises a control part, a braking part, a braking operation platform, a measurement device, a temperature measurer, multiple driving parts and multiple wheel parts; the wheel part comprises a wheel; the braking operation platform comprises an automatic braking device; the automatic braking device is connected with the braking part so as to drive the braking part to brake the wheel; the temperature measurer communicates with the braking operation platform; the temperature measurer is used for measuring the temperature of the braking part; and the measurement device is suitable for measuring the torque and the rotation speed of each wheelwhen the wheel is braked. The braking test device in the invention can accurately evaluate the braking condition of the autonomous vehicle, and simultaneously, can perform reliable verification on thecondition that the braking forced applied onto the braking part by the automatic braking device in the autonomous vehicle is changed along with the temperature of the braking part.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a braking test device and a testing method for the dynamic braking performance of an automatic driving vehicle. Background technique [0002] In the related technology, the braking performance of the vehicle needs to be tested before the vehicle is mass-produced. The existing braking test device can only test the braking performance of one wheel at a time, and cannot brake multiple wheels of the vehicle at the same time. The performance test cannot simulate the dynamic changes of the torque and speed of the vehicle's wheels, and the test results cannot accurately reflect the real situation. At the same time, it is impossible to test the braking performance of the self-driving vehicle in the prior art. [0003] In addition, when the temperature of the brake part of the self-driving vehicle is too high, the braking effect of the brake part will become worse. At this time, the automa...
