Embodiment Construction

[0041] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0042] Such as figure 1 As shown, a dual-motor-driven electro-hydraulic braking system that can actively simulate the pedal feel, including:

[0043] Brake pedal 1, which receives the driver's braking intention and inputs it into the system;

[0044] One end of the push rod 2 is connected to the brake pedal 1, and the other end is a spherical structure, which is hinged with the ball screw 4 through structural design.

[0045] The brake master cylinder 6 is used to receive the pedal force and the resultant force generated by the corresponding brake motor through the reduction mechanism to establish the required hydraulic braking force;

[0046] The fluid storage tank 7 is used to store brake fluid;

[0047] The secondary master cylinder 8 is used to receive the thrust generated by the corresponding brake motor through the reduction mechanism ...

Abstract

A double-motor driving type electronic hydraulic brake system capable of actively simulating pedal feeling comprises a brake pedal, a fluid storage tank used for storing brake fluid, a pedal displacement sensor, a pedal force sensor, a hydraulic force sensor, an electronic control unit, an electromagnetic valve, an electronic stability control module, a brake master cylinder and a secondary master cylinder. An electric control linear movement module comprises a rotating motor and a speed reduction and moment increasing mechanism which converts the rotating movement of the motor into linear movement to achieve the active control over system hydraulic brake force and pedal force. The pedal force of a driver can be fully used for reducing pressure. While the active control over the pedal force is achieved, a pedal force simulator of a complex structure is omitted, the feeling of a brake pedal is guaranteed, and the accurate automobile brake condition is fed back to the driver. The active control over the hydraulic force is achieved, and the brake requirement for automatic driving vehicles is met; maximum braking energy recovery is achieved, control is precise, and the response speed is high; double-loop braking is achieved, failure protection is considered thoroughly, and the safety is good.

Description

technical field [0001] The invention belongs to the field of automobile braking systems, and relates to a dual-motor-driven electronic hydraulic braking system capable of actively simulating the feeling of pedals. Background technique [0002] With the development of automobile technology, the performance of automobiles has been greatly improved, and the driving safety of automobiles has attracted more and more attention. Therefore, the development of automobile safety technology has become one of the important topics of automobile academic research in recent years. Different from the all-mechanical power system structure of traditional cars, the power system of clean energy vehicles has undergone great changes, and many new structural types and functional types have emerged. In order to adapt to these new structural and functional designs, traditional manufacturing The structure of the braking system is becoming more and more complex, which directly leads to problems such a...
