Problems solved by technology

The existing public series regenerative braking system not only needs to modify the original hydraulic circuit, but most of them also need to add a brake pedal simulator, which not only increases the difficulty and time of development, but also increases the cost of the braking system

Abstract

The invention discloses a semi-decoupling brake system used for regenerative braking of a new energy automobile. The semi-decoupling brake system comprises a liquid storing cup (1), a main cylinder (2), a first piston (3), a braking pedal (4), a pedal ejection rod (5), a first return spring (6), a second piston (7), a hydraulic control unit (8), rear wheels (9), front wheels (10), braking pipelines (11), a second return spring (12), a hydraulic control unit controller (13), a pedal travel sensor (14), a constant force spring (15), a vehicle control unit (16) and a driving motor (17). The semi-decoupling brake system used for regenerative braking of the new energy automobile is simple in structure, an original braking loop does not need to be changed, the difficulty is low, and the cost is low; and the semi-decoupling brake system used for regenerative braking of the new energy automobile can provide the pedal feeling similar to that of an original braking system, and meanwhile a pedal simulator is not needed, so that the cost is reduced.

Description

technical field [0001] The invention relates to vehicle braking technology, in particular to a semi-decoupling braking system for regenerative braking of new energy vehicles. Background technique [0002] Regenerative braking can improve the energy efficiency of electric vehicles, hybrid electric vehicles and fuel cell vehicles. During regenerative braking, the driving motor can be used as a generator to provide braking force to the driving wheels, convert the kinetic energy or potential energy of the vehicle into electrical energy, and store it in the power battery for the vehicle to accelerate again. [0003] To achieve regenerative braking, the brake pedal force and hydraulic braking force need to be decoupled. Existing regenerative braking systems can be classified into serial regenerative braking systems and parallel regenerative braking systems. The existing public series regenerative braking system not only needs to modify the original hydraulic circuit, but most of...
