Both active safety and fuel economy are important issues for vehicles. This paper focuses on a traction control strategy with an efficiency model in a distributed driving electric vehicle. In emergency situation, a sliding mode control algorithm was employed to achieve antislip control through keeping the wheels’ slip ratios below 20%. For general longitudinal driving cases, an efficiency model aiming at improving the fuel economy was built through an offline optimization stream within the two-dimensional design space composed of the acceleration pedal signal and the vehicle speed. The sliding mode control strategy for the joint roads and the efficiency model for the typical drive cycles were simulated. Simulation results show that the proposed driving control approach has the potential to apply to different road surfaces. It keeps the wheels’ slip ratios within the stable zone and improves the fuel economy on the premise of tracking the driver’s intention.

Abstract Due to large torque and quick response of electric motor, the traction wheels of battery electric vehicle (BEV) are easy to slip during the initial phase of starting. In this paper, an acceleration slip regulation approach based on sliding mode control algorithm is proposed to prevent the wheel slip of BEV. The traction wheel slip ratio is used as the control parameter, and a sliding mode controller is deduced from it. A fuzzy algorithm is employed to revise the switch function of sliding mode controller. After stability and robustness analysis, the sliding mode controller is validated by dynamic simulation of BEV. The sliding mode control law is transferred into vehicle control unit and is veried by road tests, the results of which show that the sliding mode controller is a good candidate to prevent the wheel slip.

Nonlinear Disturbance

The trajectory-tracking performance of the automobile electro-coating conveying mechanism is severely interrupted by highly nonlinear crossing couplings, unmodeled dynamics, parameter variation, friction, and unknown external disturbance. In this article, a sliding mode control with a nonlinear disturbance observer is proposed for high-accuracy motion control of the conveying mechanism. The nonlinear disturbance observer is designed to estimate not only the internal/external disturbance but also the model uncertainties. Based on the output of the nonlinear disturbance observer, a sliding mode control approach is designed for the hybrid series–parallel mechanism. Then, the stability of the closed-loop system is proved by means of a Lyapunov analysis. Finally, simulations with typical desired trajectory are presented to demonstrate the high performance of the proposed composite control scheme.
