A hardware-in-the-loop simulator based on dynamometers for traction control system

A hardware-in-the-loop simulator based on dynamometers to debug software and hardware of traction control system is examined in this paper, as it is able to shorten developing cycle by providing simulated low-μ or split-μ road regardless of weather. A dynamometer controller was designed with fuzzy PI method to make the torque of dynamometer regulated to the target resistance torque acted by the ground on driving wheels. Furthermore, the algorithm and hardware of ECU for traction control system were devised. The results of tests on typical roads show that the matching of software and hardware is achieved under the circumstance of the simulator.
