Problems solved by technology

[0002] In the related technology, the braking performance of the vehicle needs to be tested before the vehicle is mass-produced. The existing automatic 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 dynamic 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 autonomous vehicles in the prior art

Abstract

The invention discloses an automatic brake test device and an autonomous vehicle dynamic brake performance test method. The automatic brake test device comprises a control part, a brake part, a brakeoperation console, a measuring device, multiple drive parts and multiple wheel parts, each wheel part comprises a wheel, each drive part is used for accordingly driving one wheel to rotate, the control part is used for controlling output power of each drive part on the corresponding wheel part, the brake part is applicable to braking of the wheels, the brake operation console comprises an automatic brake device, the automatic brake device is connected with the brake part, so as to drive the brake part to brake the wheels, and the measuring device is applicable to real-time measurement on torque and rotation speed of each wheel when the wheels brake. According to the automatic brake test device disclosed by the invention, a brake test on multiple wheels of an autonomous vehicle can be simulated and dynamic torque and rotation speed changes of each wheel can be tested in a process that the wheels brake, thus braking condition of the autonomous vehicle can be more accurately evaluated.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to an automatic braking test device and a test 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 automatic 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 dynamic 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. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To ...
