Problems solved by technology

At present, there are still unformed automobile ABS performance testing and evaluation equipment, which are mainly tested by road tests, but road tests are dangerous and require a lot of time and money, especially in the development of ABS and the testing of products after crashes. The process is extremely limited
Although the cost of the bench test is low and the construction period is short, it is impossible to obtain the real state of the automobile ABS when it is working, the accuracy of the bench test is low, and the dynamic performance, working process and fault parameters of the ABS are not easy to obtain

Description

technical field [0001] The invention belongs to the technical field of automobile safety situations, and in particular relates to a device and method for detecting automobile braking performance. Background technique [0002] At present, there are mainly two types of automotive ABS performance testing and testing: road test and bench test. Road tests are widely used in automotive ABS performance testing and testing. However, the current road test equipment is expensive, the parameter acquisition process is complicated, and the equipment installation and positioning requirements are high. It is difficult for ordinary scientific research units to conduct independent tests. For the detection and test of automobile ABS performance, a device with simple equipment, convenient installation, high detection accuracy, low cost, and accurate and timely analysis is required to complete. [0003] After the car brakes rapidly at high speed, the tires will often slip on the road. In the c...
