Embodiment Construction

[0029] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0030] figure 1 A schematic diagram of a novel dual-motor electromechanical hydraulic braking system according to an embodiment of the present invention is shown.

[0031] Such as figure 1 As shown, the electromechanical hydraulic braking system mainly includes: an electronically controlled linear motion module 30 , a brake master cylinder 11 , a pedal force simulation motor 2 and a brake pedal 1 . The brake pedal 1 is equipped with a displacement sensor 25, the displacement sensors 25 are two and mutually checked, and the displacement sensor 25 can determine the speed and displacement of the brake pedal 1 when it is stepped on.

[0032] In this embodiment, the electronically controlled linear motion module 30 includes a brake motor stator 21 , a linear motion mechanism 32 , and a brake motor rotor 26 . The brake motor stator 21 drives the b...

Abstract

The invention discloses a mechanical, electronic and hydraulic brake system which is used for a vehicle and comprises a brake pedal, sensors, a brake master cylinder, an electronic-control linear driving module, a pedal force simulation module and two linear motors. The sensors are used for acquiring the speed and displacement when the brake pedal is treaded; the brake master cylinder is connected with four wheel cylinders by wheel cylinder hydraulic pressure control valves; the electronic-control linear driving module is directly connected with the brake master cylinder and drives a piston of the brake master cylinder to linearly move according to signals from the sensors; the pedal force simulation module provides brake feel for a driver by the aid of motors and corresponding transmission mechanisms; the two linear motors are serially connected with each other, a shaft of one of the two linear motors is connected with the brake pedal, a shaft of the other motor is connected with a shell of the first motor and directly pushes the master cylinder to generate pressure, and a shell of the other motor is fixedly connected with a vehicle body. The mechanical, electronic and hydraulic brake system has the advantages that an integration level of the brake system can be obviously upgraded, functions of the brake system can be obviously increased, the pedal feel can be guaranteed, and the reliability of the system can be guaranteed owing to a mechanical connection mode.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to automobile braking technology, in particular to a mechanical electronic hydraulic braking system. Background technique [0002] The electronic hydraulic braking system refers to a braking system in which the brake pedal and the hydraulic braking force are disconnected, and the energy required for braking is usually provided by the relevant energy supply system. As the efficiency of engines continues to increase, the vacuum they can provide becomes more and more limited. Therefore, many vehicles adopt the scheme of adding a vacuum pump to increase the vacuum degree. However, this solution is only a temporary solution. As the electronic hydraulic braking system has the characteristics of fast response and strong function, it is attracting more and more attention. [0003] In 1997, Toyota Corporation of Japan launched the Prius, a hybrid car with electronic braking function. T...
