Embodiment Construction

[0038] Before the application is explained, the relevant technologies are described as follows:

[0039] In a traditional car, the torque generated by the engine must pass through mechanical devices such as gears and transmission shafts to drive the wheels forward. During this process, part of the energy will be consumed by mechanical motion. Among them, the axles that drive the wheels forward through mechanical devices such as gears and transmission shafts are called mechanical axles.

[0040] The electric vehicle equipped with a motor (the axle driven by the motor to move the wheels is called an electric axle), compared with the traditional car, simplifies the mechanical transmission mechanism, and the electric energy generated by the battery is directly transmitted to the motor arranged in the wheel. The energy loss in the mechanical transmission process is greatly reduced, and the efficiency of the motor drive is greatly improved. Not only that, electric wheel vehicles ca...

Abstract

The invention discloses a composite brake control system. The system comprises a composite controller, at least one mechanical axle and at least one electric axle, wherein the mechanical axle comprises a first proportional relay valve and two first wheel ABS brake modules, the two first wheel ABS brake modules are used for braking first wheels at the two ends of the mechanical axle correspondingly, the electric vehicle axle comprises two second wheel brake modules, and the two second wheel brake modules are used for braking electric wheels at the two ends of the electric vehicle axle correspondingly; the first proportional relay valve, the two first wheel ABS brake modules and the two second wheel brake modules are electrically connected with the composite controller; and the two first wheel ABS brake modules are respectively connected with the first proportional relay valve through pipelines. According to the composite brake control system, regenerative braking systems of the electricwheels can perform energy recovery, so that ABS braking systems and the regenerative braking systems can be coordinated and matched.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a composite braking control system. Background technique [0002] With the continuous development of automobiles, a variety of automobiles have emerged, including traditional automobiles utilizing gasoline and electric automobiles driven by electric energy. Traditional cars use ABS braking system, which can avoid the phenomenon of tire locking; compared with traditional cars, electric cars simplify the mechanical transmission mechanism, so that the efficiency of motor drive is greatly improved, and regenerative braking systems can also be configured, that is, electric cars By means of the power generation function of the motor in the electric wheel, the braking torque generated during the braking process can be recovered to form braking energy. [0003] However, in the related art, the ABS braking system and the regenerative braking system cannot work in coordination, so tha...
