The vehicle sideslip angle is one of the most important variables to evaluate vehicle stability during dynamic maneuvers. The vehicle dynamic represented by the single track vehicle model with linear tire is firstly introduced, a novel method of virtual sensor based on extended Kalman filter for the estimation of vehicle sideslip angle is proposed. Results of simulation using CarSim and co-simulation...
Recently electric vehicles are taken up as successor to conventional gasoline engine vehicles and many researchers have focused on motion control of electric vehicle. This paper describes a strategy to assist the vehicle driver using an accelerator pedal and a steering wheel is considered. In particular, the accelerator pedal is called haptic pedal and the combination control of steer-by-wire and...
In this paper, we propose a yaw moment control based on fuzzy-logic controller to enhance the vehicle stability. A two-degree-of-freedom nonlinear model of the considered vehicle is briefly presented. The feedback of the yaw rate and sideslip angle are regarded as inputs of the controller. The developed controller generates the suitable steering angle so that the vehicle follows the target values...
This paper presents a motion control method of 6WD/6WS (6-wheel-drive and 6-wheel-steering) vehicle using optimum tire force distribution method. When we make used of independent driving and steering system, the motion control performance of the 6WD/6WS vehicle can be improved. For example, vehicle's maneuverability is more improved at low speed and vehicle's stability is also improved at high speed...
The motion of a vehicle is governed by the forces generated between the tires and the road. Knowledge of these dynamic variables is important for vehicle control systems that aim to enhance vehicle stability and passenger safety. Unfortunately, it is difficult to obtain these data because of technical and economic reasons, therefore, they must be estimated. This study introduces a new estimation process...
Although the conventional PID controller is widely used, there has been limited success in the yaw moment control of the vehicle with obvious nonlinearities. This paper presents a controller based on self-tuning fuzzy PID to improve vehicle handling and stability simultaneously. The controller contains a conventional PID controller and fuzzy controller which could tune the parameters of PID controller...
