Problems solved by technology

[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

Abstract

The invention discloses a computer-control-based ABS simulation platform comprising a computer, a simulation device connected with the computer electrically, and an electronic control unit connected with the simulation device electrically. According to the computer-control-based ABS simulation platform, an SOPC-based software and hardware collaborative development technology is employed for completing a hardware-in-loop simulation device; and the ABS simulation platform uses the hardware-in-loop simulation device to realize the hardware-in-loop simulation function. A vehicle kinetic model is operated in the hardware-in-loop simulation device and a control instruction from the electronic control unit is received to simulate the performance characteristic of the vehicle in a brake state, thereby achieving an objective of testing a control system.
