“…Therefore, DDEHB is able to flexibly regulate braking force and has many advantages in electric vehicle. (1) Electric vehicle battery supplies electric energy to DDEHB directly, it is unnecessary to convert electric energy to high-pressure hydraulic using master cylinder. Not only energy supply of DDEHB is ensured, but also energy conversion loss and transmission loss are avoided.…”

“…The brake system continues to develop because of pursuing of braking safety by human beings, resulting in a number of components integrated into hydraulic brake system, such as anti-lock braking system (ABS), traction control system (TCS) and electronic stability program (ESP) [1]. Although braking performance is typically improved, hydraulic brake system is more complex and still unable to regulate braking force independently and accurately [2].…”

For the characteristics of full electric propulsion, a novel kind of brake-by-wire unit is designed for electric vehicle to improve braking performance. A comprehensive brake-by-wire system including this unit is set up after its structure and principle are introduced. Then, a multi-layer fuzzy controller is proposed to regulate decelerate and wheel slip rate, and an optimal regenerative strategy is proposed to recover braking energy. At last, the experiment of brake unit is completed to verify that this novel unit is technologically feasible, and an electric vehicle co-simulation model based on MATLAB/Simulink and AMESim is established to prove that this novel unit is able to significantly improve braking performance of electric vehicle. The simulation result shows braking distance and time are shorten by 12.19% and 15.54% respectively compared with conventional ABS system in the same braking condition, and the recovery efficiencies in light and heavy braking are 53% and 28% respectively.

“…An important issue for the chassis control systems is to control the lateral vehicle motion variables such as the yaw rate and side-slip angle by controlling the vehicle yaw moment. Active steering systems in front (AFS) or both in front and rear (4WS) can effectively improve the steerability performance in the linear region of the tire (Hwang et al, 2008;Jinlai et al, 2011). Kang et al (2008) investigated the steering controller for path-tracking and a speed controller for improving the safety of lateral vehicle behavior.…”

In this paper, an optimal controller for integrated longitudinal and lateral closed loop vehicle/driver dynamics proposed to follow desired path in various driving maneuvers, which also improved maneuverability and stability of vehicle over desired path. Designed controller imposed corrected steering angle and torque on the wheels to keep the vehicle on the desired trajectory whilst modified its handling properties. In the next stage, performance of proposed optimal linear quadratic regulator (LQR) controller compared with Proportional-integrated-derivative (PID) one. The proposed controllers has been implemented on vehicle eight degree of freedom model in MATLAB/Simulink. Then the effects of adaptive controller on vehicle path following has been examined for various maneuvers, by driving on the lane change, J-turn, double lane-change and desired tracks. Finally, longitudinal dynamic performance of vehicle has been investigated during severe braking conditions. Simulation results indicated the dominate efficiency of controller on the vehicle stabilization and path following. Also, it improved longitudinal dynamics performance by preventing wheel lock and reducing stopping distance.

“…The proposed control structure which consisted of a feed-forward controller and a feedback controller could make the side slip angle and the yaw rate track the desired values from the reference vehicle model. Men et al 16 used the 2-DOF 4WAS vehicle model as the internal model and designed a 4WAS internal model control system. Simulating via 11-DOF vehicle model, the 4WAS internal model control system had been shown to have a better performance in vehicle stability task.…”

From the perspective of vehicle dynamics, the four-wheel independent steering vehicle dynamics stability control method is studied, and a four-wheel independent steering varying parameter linear quadratic regulator control system is proposed with the help of expert control method. In the article, a four-wheel independent steering linear quadratic regulator controller for model following purpose is designed first. Then, by analyzing the four-wheel independent steering vehicle dynamic characteristics and the influence of linear quadratic regulator control parameters on control performance, a linear quadratic regulator control parameter adjustment strategy based on vehicle steering state is proposed to achieve the adaptive adjustment of linear quadratic regulator control parameters. In addition, to further improve the control performance, the proposed varying parameter linear quadratic regulator control system is optimized by genetic algorithm. Finally, simulation studies have been conducted by applying the proposed control system to the 8-degree-offreedom four-wheel independent steering vehicle dynamics model. The simulation results indicate that the proposed control system has better performance and robustness and can effectively improve the stability and steering safety of the four-wheel independent steering vehicle.
