A Study of Coordinated Vehicle Traction Control System Based on Optimal Slip Ratio Algorithm
Gang Liu, LiQiang Jin
Source abstract
Under complicated situations, such as the low slippery road surface and split- μ road surface, traction control system is the key issue to improve the performance of vehicle acceleration and stability. In this paper, a novel control strategy with engine controller and active pressure controller is presented. First and foremost, an ideal vehicle model is proposed for simulation; then a method for the calculation of optimal slip ratio is also brought. Finally, the scheme of control method with engine controller and active brake controller is presented. From the results of simulation and road tests, it can be concluded that the acceleration performance and stability of a vehicle equipped with traction control system (TCS) can be improved.
