“…The steer-by-wire (SBW) system is a new type of steering system that eliminates the mechanical structure between the steering wheel and the steering gear. [1][2][3] Due to its flexible steering transmission ratio, it can reduce the driver's burden and enhance the steering response speed and driving stability of the vehicle. Cars with steer-by-wire can be driven in both manual and automatic driving modes.…”

Intelligent vehicles require the ability to switch freely between manual and automatic driving modes, which opens up more possibilities for steer-by-wire. Among them, the design of transmission ratio for both driving modes can improve the steering performance of vehicle. In the manual driving mode, this paper optimizes the yaw rate gain upon the particle swarm optimization (PSO) algorithm and designs a variable steering transmission ratio, which can reduce the driver’s burden and improve the vehicle’s handling stability. Further, the steering wheel angular rate information and fuzzy control are used to design the high-speed transmission ratio to ensure the safety of the vehicle in high-speed emergency situations. In the automatic driving mode, the transmission ratio values at various vehicle speeds are optimized offline based on the PSO algorithm, and a variable transmission ratio curve is designed to enhance the trajectory tracking ability and the vehicle stability. Finally, the hardware-in-the-loop test results show that the variable transmission ratio designed in the manual driving mode reduces the burden of the driver at low speed and improves the vehicle stability at high speed, especially in emergency situations. It also proves that the optimized design of variable ratio in the automatic driving mode promotes the path-following ability and the vehicle stability.

“…This study proposes a new vehicle integrated robust model matching controller (R-MMC) that cooperates four wheel steering and direct yaw moment control to improve the vehicle handling performance and stability [16]. [17] Proposes a chassis integrated control system theoretically utilizing SBW system by using 4WS method to improve vehicle handling and stability. In order to improve the lateral stability of the vehicles at a high speed, a DYC control method is applied to four-wheel steering vehicle control [18].…”

In this paper, a 4 wheel steering vehicle (4WS) was used as template by bicycle model and using 3 degree of freedom system (experimental). The dynamics governing the YawlRolI behavior of a vehicle has been simulated with MA TLAB/SIMULINK software. To control this vehicle a controller with two levels was considered. High level: 4WS fuzzy controller that adjusts the rear angle of tires according to the front angle of tires and the electronic stability program (ESP) fuzzy controller which acts on the brake system to generate a corrective yaw moment that guides the vehicle back to the desired track when vehicle is deviating from its track. Two of them worked in parallel actions; consequently, the directional stability property was enhanced. Low level: P-action controllers were used to optimize the results. The results was investigated with vehicle has a very high lateral stiffness which there is infinitesimal slipped on turning or maneuvering (reference), this allows us to correctly identify the amount of slipping in our experimental vehicle, finally, all results was compared with a 2 wheel steering vehicle uncontrolled and a 4 wheel steering vehicle controlled. The results are promising and showed us enhancement significantly.
