Embodiment Construction

[0033] Specific embodiments of the present invention such as figure 2 As shown, 1 is the wheel speed sensor, 2 is the brake controller, 3 is the wheel friction brake, 4 is the axle shaft, 5 is the motor controller, 6 is the motor, 7 is the main reducer, 8 is the brake air pressure sensor, 9 is a brake air pressure regulating valve, 10 is a gas cylinder, 11 is a brake pedal position sensor, and 12 is a double-chamber tandem brake valve. The brake controller 2 has a signal circuit connection with the wheel speed sensor 1, the motor controller 5, the brake air pressure sensor 8, the brake air pressure regulating valve 9, and the brake pedal position sensor 11. The gas path starts from the gas cylinder 10, first passes through the dual-chamber tandem brake valve 12, then passes through the brake air pressure regulating valve 9, the brake air pressure sensor 8, and finally connects to the wheel friction brake 3. Motor 6 is connected with motor controller 5 by high-power circuit, ...

Abstract

The invention relates to a hybrid brake system with an anti-lock braking function and a control method, which belongs to the technical field of hybrid power electric automobile, in particular to a serial braking energy feedback system which is provided with a braking air pressure adjusting mechanism and has the anti-lock braking function based on the system. The serial braking energy feedback system achieves serial feedback brake strategy under normal braking conditions through harmonizing feedback brake and friction brake, can ensure braking feeling at the same time of effectively recycling braking energy, and achieves the united anti-lock control strategy for the friction brake and the feedback brake when the wheel is locked or trends to be locked. The serial braking energy feedback system simplifies complexity of a braking system of the hybrid power electric automobile greatly, improves integrated degree of control, and can effectively recycle the braking energy at the same time of ensuring braking safety.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, and particularly relates to a set of hybrid braking systems for rear-wheel drive vehicles that can perform friction braking and motor feedback braking. Coordinate friction braking and motor regenerative braking for anti-lock braking control. Background technique [0002] With the development of roads, the speed of city buses increases continuously, the possibility of emergency braking increases, and the importance of anti-lock braking increases. By effectively controlling the wheel slip rate, the anti-lock braking system can reduce the degree of tire wear and reduce the operating cost of urban buses. [0003] The developed braking energy feedback system, see invention patent 200610113586.8 "electric vehicle hybrid braking system", is mainly used in city buses, and has been successfully applied in a certain type of HCNG series hybrid city bus and a certain type of fuel cell city ...
