“…DYC reduces the sideslip angle of front axle, which is consistent with the reduction in steering angle. Although some increase occurs on the sideslip of rear axle in IEV, the rear wheels is still in linear area and make the front wheel in linear area, too, which may play an important role in the estimation of the vehicle sideslip angle [22], [23].…”

Direct yaw moment becomes an external input to in-wheel-motors (IWMs) electric vehicles (IEVs) besides steering angle usually as the only input to traditional vehicles. To improve the handling and stability of IEVs, a good knowledge of the effect brought by direct yaw moment is necessary. First, in this paper, reference model based on 2 DOF bicycle model is built for the control strategy. Second, vehicle model is built, and DYC based on sliding mode algorithm is proposed by using model based control method to evaluate the impact on the vehicle behavior. Then, simulations on different maneuvers are carried out and the values of vehicle states are compared especially in wheel steering angles and axle sideslip angles. Finally, conclusions are given.

This paper introduces a PWM two machines single inverter (TMSI) for electric vehicle drive systems. This structure, which has single inverter for independently driven two DC motors, enhances efficiency for electrical vehicle (EV) from two points of view. Firstly, by superseding clutch, reduction gears, differential gears box and other mechanic organ which are the main reasons of losses, while power is transmitted through them to the wheels. Secondly, the proposed structure composed of robust simple inverter that enhances efficiency by reducing the number of power electronic switches as well as can be controlled much easer than the conventional complex derive converters. The simplicity of the structure from practical point of view is very attractive. The simulation results of the proposed direct-wheeldriven are obtained to confirm the theoretical description of the controller and motors by PSCAD/EMTPDC simulator software.

“…Moreover, a combination of direct yaw-moment and active front steering controllers for electric vehicles with four in-wheel motors is proposed as a stability control system in Ref [4]. A torque-control distribution for an electric vehicle is presented in Ref [5] that takes advantage of front-wheel drive, rear-wheel drive, and all-wheel drive configurations in vehicles. The applications of electric braking control systems and traction control systems in electric vehicles are presented in Refs.…”

This paper presents the implementation of an off-line optimized torque vectoring controller on an electric-drive vehicle with four in-wheel motors for driver assistance and handling performance enhancement. The controller takes vehicle longitudinal, lateral, and yaw acceleration signals as feedback using the concept of state-derivative feedback control. The objective of the controller is to optimally control the vehicle motion according to the driver commands. Reference signals are first calculated using a driver command interpreter to accurately interpret what the driver intends for the vehicle motion. The controller then adjusts the braking/throttle outputs based on discrepancy between the vehicle response and the interpreter command. A test vehicle equipped with four in-wheel electric motors, vehicle sensors, communication buses, and dSPACE rapid prototyping hardware is instrumented and the control performance is verified through vehicle handling tests under different driving conditions.
