The present paper describes a longitudinal control strategy in time-varying road surface adhesion conditions, for a vehicle equipped with 4 in-wheel electric motors. The controller task is to ensure two main functions : braking (achieving an ABS-like function, i.e., no wheel skid), and traction control (TCS-like function, i.e., low wheel slip) using the electric motor torques as the unique actuators...
This paper presents a road condition estimator based on the wheel acceleration and a torque controller for a vehicle equipped with an electric motor. In the first step, the instantaneous friction coefficient and the maximum friction coefficient between the wheel and the road are estimated, without knowing a priori the road conditions. Next, a longitudinal controller is set up to ensure the two main...
This paper focuses on a front-and-rear-wheel-independent-drive-type-electric vehicle (FRID EV) which is being developed as the next generation EV with ideal characteristics of driving performance. Since the FRID EV has propulsion systems which can control the driving and braking torques of the front and rear wheels independently, various outstanding and indispensable functions are produced. The FRID...
A novel power assisted steering system was proposed in this paper, due to the independent driving characteristics of electric vehicle (EV) with four-wheel-independent-drive. The basic theory of differential drive torque assisted steering is discussed at first. After that, vehicle dynamics model with steering system was built in SIMULINK, and the control strategy for minimizing the difference between...
