This paper discusses the vehicle dynamics control system of an all-wheel-drive electric vehicle with four on-board motors. Each driveline is characterized by complex torsional dynamics caused by the gearbox and the half-shaft located between the electric motor and the wheel. Such a drivetrain configuration can benefit from a specific controller, i.e., the active vibration controller (AVC), which increases...
Wheel slip control for ground vehicles with individually controlled electric motors can be realized with strategies that can significantly differ from the conventional antilock braking system (ABS) and traction control (TC) system. This paper provides a review of state-of-the-art technology and recent developments in TC and ABSs using the actuation of electric motors. Particular attention is paid...
The paper introduces the anti-lock braking system (ABS) designed for the all-wheel drive full electric vehicle equipped with four on-board motors. The main features of the ABS under consideration are (i) continuous wheel slip control with feedforward and feedback controller parts, and (ii) versatile actuation architecture realizing pure electric braking, braking with electro-hydraulic decoupled brake...
This paper provides a new approach for emulating electric vehicle (EV) braking performance on a motor/dynamometer test bench. The brake force distribution between regenerative braking and friction braking of both the front and rear axles are discussed in detail. A brake controller is designed, which represents a very close model of an actual EV braking system and takes into account both regenerative...
A new composite ABS control method for EV with four independently-driving wheels is presented. Combinating the best braking energy recovery strategy and the ideal braking force distribution control strategy, we designed a new strategy of braking force distribution for EV with four independently-driving wheels, and proposed a new composite ABS control method based on cooperative work of electric motor...
Braking force distribution plays an important role in energy recovery of electric vehicles. A methodological approach for the braking force distribution using genetic algorithm is described. In view of vehicle stability, motor characteristic and battery safety, a constrained optimization problem is formulated. The objection is to maximize regenerated brake energy, and various limitations are considered...
Braking force distribution of an electric vehicle has an important impact on braking performance and energy recovery. With the analysis of braking dynamics and the establishment of motor model, a braking force distribution strategy is proposed from the viewpoint of maximum energy recovery. From another point of view, how to distribute the braking force can be thought as a constrained optimization...
