Yaw Rate Sensor for Vehicle Dynamics Control System

Since the handling behaviour of car-trailer combination is more complex and less predictable than that of non-articulated vehicles, the drivers may lose control of the vehicle in some hasty steering maneuvers. The kinematics of car-trailer combination has been analyzed with a 3 DOF model. A modified Vehicle Dynamics Control system was designed to improve the lateral stability of the trailer. The dynamics simulation for lateral stability of car-trailer combination has been performed on the multi-body model. The results show that the lateral stability of car-trailer combination, including yaw rate and roll angle has been improved with the modified Vehicle Dynamics Control system.

Yaw Moment

The paper presents a vehicle dynamics control strategy devoted to prevent vehicles from spinning and drifting out. With vehicle dynamics control system, counter braking are applied at individual wheels as needed to generate an additional yaw moment until steering control and vehicle stability were regained. The Linear Quadratic Regulator (LQR) theory was designed to produce demanded yaw moment according to the error between the measured yaw rate and desired yaw rate. The results indicate the proposed system can significantly improve vehicle stability for active safety.

Vehicle Dynamics Control

This paper describes the design of a vehicle dynamics control system for improving handling and stability of electric vehicle. A vehicle with this control system can facilitate good handling performance under normal operating conditions and enhance stability under critical conditions. A feedforward and a feedback controllers are employed to make the vehicle follow the reference yaw rate based on a non-linear 5DOF vehicle model under normal operating conditions. When the tire tends to reach physical limit, the reference value will be modified with lateral acceleration feedback. Finally, simulation is conducted under several standard maneuvers and the results verify the effectiveness of the proposed control system.
