In accordance with the developing trend of “safety, comfort and low-carbon” technology, the market for intelligent X-by-wire chassis is huge. A new requirement of the X-by-wire system, including the response, accuracy, energy consumption and fault-tolerance, is put forward. Based on the analysis of the structure and design flow of the brake-by-wire (BBW) system, this paper analyzes the research status and development trend of the control methods of braking force, coordination control strategies and fault-tolerant control of the BBW system. The application possibilities of direct-driving technology in the BBW system are analyzed. At present, the key points of research focus on considering the influence of the multi-field coupling effect in the design, observing and compensating various nonlinear factors, and having a higher requirement for fault-tolerant control. Finally, an intelligent direct-driving BBW system is proposed as a research direction, which takes high efficiency and energy saving as a foothold and aims at breakthroughs in dynamic response, control accuracy and fault-tolerant abilities.

“…15 After considering the nonlinear characteristics of the EHB system and establishing the simplified dynamics model, it is necessary to design a pressure controller for the braking system. To improve the control precision, many control approaches have been proposed, such as Fault-Tolerant control, 16,17 adaptive control, 18 neural network control, 19 and model predictive control, 20 which are applied into the braking system. Zhao et al introduced a nonlinear backstepping control algorithm for the EHB system.…”

Brake-by-wire system for self-driving vehicles requires hydraulic pressure response of the master cylinder to be quick in the braking process, making its long-term precision paramount. This is particularly challenging for braking in response to the command of virtual driver instead of the real driver, for which the hydraulic pressure is nonlinear with the electric motor’s torque. While much of the research on brake-by-wire has focused on improving energy regeneration and vehicle stability, comparatively little is known about the braking pressure control of self-driving vehicles. Therefore, we develop a novel architecture of the electro-hydraulic brake-by-wire adopting ball screw for the self-driving, in which there is a quadratic-polynomial relationship between the position of the electric motor and the brake pressure of the master cylinder. The brake-by-wire dynamics model is built by the speed of the electric motor and the brake pressure of the master cylinder, and a sliding mode control law is designed based on the pressure demand of the master cylinder. Here we discuss a series of studies on electro-hydraulic braking dynamics that, collectively, design a pressure demand control approach of how the sliding mode controller operates the master cylinder pressure by the electric motor torque. Testing and analyzing the designed approach embedded into the braking control unit is applied to a vehicle test bench brake-by-wire to fully realize the accurate pressure tracking of the electro-hydraulic brake-by-wire system.

This review paper audit and talks about the four-wheel slowing mechanism which is autonomous for enhanced vehicle dependability and tire-street grating is obscure. Vehicle's security ought to be ensured for the vehicle to be steady under obscure street conditions. Braking is that vital part in a car without which a car can't be made or can't keep running on streets. Certain tests and reproductions made through PC programming demonstrates that solidness can be kept up under different conditions. The innovation talked about is generally utilized in vehicles to enhance the solace and wellbeing.
