Abstract :
The steering dynamics of distributed driving vehicle with Torque Vectoring steering is different from that of the traditional Ackermann steering. A linear 2DOF vehicle dynamic model of distributed driving vehicle with Torque Vectoring steering is established and the relationships among steering torque, forward speed and steering radius are derived. A multi-body dynamic model of the Torque Vectoring steering vehicle is established based on ADAMS and the model is validated by simulation. The simulation result shows that the deviation of 2DOF mathematical model is within 10% while the vehicle speed is less than 15m/s and the steering radius is more than 30m. Therefore, the 2DOF dynamic model can be used to analyze the control system of distributed driving vehicle with Torque Vectoring steering, but it only applies to low-speed and large-steering-radius conditions.
