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 the braking system. Many additional mechanisms are installed on the brake line, which makes the structure of the brake system more complicated, and also increases the hidden danger of hydraulic circuit leakage and the difficulty of assembly and maintenance

Embodiment Construction

[0031] 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.

[0032] According to one aspect of the present disclosure, a brake-by-wire system is provided, including an electronic pedal 200 , a hydraulic system, a hydraulic control unit 910 , two hydraulic brakes 410 , a controller, and two electric brakes 420 .

[0033] 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 moni...

Abstract

The present disclosure provides a line control braking system and a vehicle. The line control braking system includes a pedal signal collector, a controller, a hydraulic system, a hydraulic control unit, two electric brakes, and two hydraulic brakes, wherein the electric brakes are front wheel brakes and the hydraulic brakes are rear wheel brakes, or the electric brakes are rear wheel brakes and the hydraulic brakes are front wheel brakes; the controller is configured to control the electric brakes according to a pedal signal collected by the pedal signal collector; and the hydraulic control unit is configured to control the hydraulic pressure provided by the hydraulic system for the hydraulic brakes according to the pedal signal. The line control braking system is simple in structure andis suitable for being arranged on the vehicle.

Description

technical field [0001] The present disclosure relates to a vehicle braking system, in particular, to a brake-by-wire braking system and a vehicle. Background technique [0002] The brake-by-wire system is referred to as BBW or electronically controlled brake system, which is divided into mechanical brake-by-wire system (EMB) and hydraulic brake-by-wire system (EHB). If EHB is called a "wet" BBW system, then EMB is a "dry" BBW system. The difference between the two is that EMB no longer uses brake fluid and hydraulic components, and the braking torque is completely realized by the motor-driven actuator installed on the four wheels, while EHB is a braking system between the traditional hydraulic braking system and EMB. The dynamic system is a transitional system. [0003] The mechanical brake-by-wire brake system, referred to as EMB, is completely different from the traditional hydraulic brake system. The traditional hydraulic brake system has been a very mature technology ...
