[0002] Vehicle anti-lock braking system (ABS) is a mechatronic system that uses electronic control technology on the basis of traditional braking systems to prevent wheel locking during braking. It is an important part of the automotive braking safety system. With the enhancement of people's awareness of driving safety and the formulation of relevant national laws and regulations, ABS is currently widely used in various vehicles. Comprehensive and comprehensive testing, especially under fault conditions and extreme conditions, is particularly important. When testing ABS electronic control units (ECUs), the traditional method requires a real car to test the car, which is expensive and easily limited by the environment. and it's hard to do certain limit tests
