Problems solved by technology

With the continuous improvement of people's requirements for braking performance, anti-lock braking system (ABS), traction control system (TCS), electronic stability control program (ESP), active collision avoidance technology (ACC) and other functions are gradually integrated into In the braking system, more and more additional mechanisms are installed on the braking circuit, which makes the structure of the braking system more complicated, and also increases the hidden danger of hydraulic circuit leakage and the difficulty of assembly and maintenance.

Embodiment Construction

[0028] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0029] According to an aspect of the present disclosure, such as figure 1 As shown, a brake-by-wire system is provided, including an electronic pedal 200 , a controller, two electric brakes 410 , and two wheel-side motors 420 .

[0030] The electronic pedal 200 includes a brake pedal 210 , a pedal simulator 220 and a pedal signal collector 230 . The pedal simulator 220 provides the driver with a pedal feeling (pedal reaction force and pedal stroke) similar to that of a traditional braking system, so that the driver can perform braking operations according to his own habits and experience. The pedal signal collector 230 is used to monitor the driver's manipu...

Abstract

The present disclosure relates to a brake-by-wire system and a vehicle. The brake-by-wire system includes a pedal signal collector, two electric brakes, a controller, and two wheel-side motors, the two electric brakes are used to brake two front wheels, and the two wheel-side motors are used to Drive and brake two rear wheels; or, the two electric brakes are used to brake two rear wheels, and the two wheel side motors are used to drive and brake two front wheels, and the wheel side motors include The motor body and the first electromagnetic clutch, the first electromagnetic clutch is used to brake the motor shaft of the motor body, and the controller is used to control the electric brake and the intermediate motor according to the pedal signal. Through the above technical solution, the present disclosure can provide a brake-by-wire system with few mechanical connections, no hydraulic brake pipeline, simple structure, small volume, easy to arrange on the vehicle, and can effectively reduce the weight of the vehicle.

Description

technical field [0001] The present disclosure relates to vehicle braking systems, and in particular, to a brake-by-wire system. Background technique [0002] The brake-by-wire system is an electronically controlled brake system, which is divided into a mechanical brake-by-wire system and a hydraulic brake-by-wire system. [0003] The mechanical brake-by-wire system (EMB for short) is completely different from the traditional hydraulic brake system. The traditional hydraulic brake system has been a very mature technology since its development. With the continuous improvement of people's requirements for braking performance, anti-lock braking system (ABS), traction control system (TCS), electronic stability control program (ESP), active collision avoidance technology (ACC) and other functions are gradually integrated into In the braking system, more and more additional mechanisms are installed on the braking circuit, which makes the structure of the braking system more compl...
