Abstract

The invention relates to an electro-hydraulic compound brake system using an integrated brake master cylinder assembly. The electro-hydraulic compound brake system comprises a compound braking control unit, a hydraulic braking subsystem and a motor regenerative braking subsystem. The compound braking control unit is respectively connected with the hydraulic braking subsystem and the motor regenerative braking subsystem. The hydraulic braking subsystem is formed by the integrated brake master cylinder assembly (10) and a hydraulic control unit (30), wherein the integrated brake master cylinder assembly (10) is formed by an integrated brake master cylinder and high-pressure oil sources. Compared with the prior art, the electro-hydraulic compound brake system using the integrated brake master cylinder assembly has the advantages of being simple in structure, convenient to achieve, low in cost, good in expansibility and applicability, and the like.

Description

technical field [0001] The invention relates to an automobile brake system, in particular to an electro-hydraulic composite brake system using an integrated brake master cylinder assembly. Background technique [0002] The powertrain of new energy vehicles such as pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicles all use the motor-battery as the core to form an electric drive system. Kinetic energy recovery function. The use of regenerative braking can effectively recover the energy originally dissipated as heat energy during vehicle braking, and improve the energy utilization efficiency, fuel economy and emission performance of new energy vehicles. Since the motor feedback braking torque is limited by the external characteristics of the motor and the charging characteristics of the battery, it cannot meet the vehicle braking requirements on roads with high adhesion coefficient or high-speed emergency braking. The electro-hydraulic composite ...
