To improve the comprehensive performance of distributed wheel-side four-wheel-drive electric bus, problem optimal distribution driving torque four motors is studied. Aiming at poor economy and failure switching control due to consideration both straight steering conditions, this paper proposes a fuzzy yaw moment strategy based on golden section search algorithm. Under full working according eff...

This work develops an advanced control system to improve the handling, comfort, and longitudinal lateral stability of a four-wheel-independent-drive electric vehicle, based on combination control. Firstly, avoid wheels from slipping or locking when accelerating braking combining traction is proposed. The coordinated ASR/ABS can operate as acceleration slip regulation (ASR) by preventing during ...

For 4MIDEV with differential steering, the trajectory tracking multi-objective control method is studied. The dynamics model of four-in-wheel motor independent-drive vehicle (4MIDEV) established comprehensively considering steering characteristics, longitudinal and lateral characteristics. Takagi Sugeno (T-S) fuzzy adopted to deal nonlinear time-varying characteristics parameters such as speed ...

This paper presents a simple sliding mode control strategy used for an electronic differential system for electric vehicle with two independent wheel drives. When a vehicle drives along a curved road lane, the speed of the inner wheel has to be different from that of the outer wheel in order to prevent the vehicle from vibrating and travelling an unsteady path. Because each wheel of this electr...

A novel vehicle traction algorithm solving the force allocation problem based on center point motion feedback controller is proposed in this paper. The control system utilizes individual wheel torque actuation assuming all wheels are individually driven. approach presented an alternative to various direct optimization-based force/torque schemes. has many benefits, such as significant reduction ...
