Hardware-in-the-loop simulation of traction control system based on gear-shift intervention in automatic mechanical transmission

Based on the previously developed traction control system,a gear-shift intervention strategy in an automatic mechanical transmission for the traction control was presented.A software-and hardware-in-the-loop simulator was erected,and bench tests on the typical adhesion roads were made.The results show that the traction control system,based on the combined regulation of the engine,the transmission and the brake can effectively improve the vehicle accelerating performance on the low-μ roads.
