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

[0029] 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.

[0030] 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 an intermediate motor 420 .

[0031] 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 line control braking system and a vehicle. The line control braking system includes a pedal signal collector, two electric brakes, a controller, and an intermediatemotor, wherein the two electric brakes are used for braking two front wheels and the intermediate motor is used for driving and braking two rear wheels, or the two electric brakes are used for braking the two rear wheels and the intermediate motors is used for driving and braking the two front wheels; the intermediate motor includes two motor bodies and two first electromagnetic clutches for braking the motor shafts of respective motor bodies; the controller is used for controlling the electric brakes and the intermediate motor according to a pedal signal. Through the above technical solution, the present disclosure can provide the line control braking system with less mechanical connection, no hydraulic brake pipeline, simple structure and small size, easy to be arranged on the vehicle,and capable of reducing 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...
