Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings. The following descriptions of the embodiments of the present invention are only for illustration rather than limiting the present invention.

[0046] Figure 1 is a schematic structural diagram of the regenerative braking and anti-lock braking integrated control system of a hybrid car. It can be seen from the figure that the car is a serial hybrid car with front-wheel drive and regenerative braking only on the front axle. However, the idea of ​​the present invention is equally applicable to other types of hybrid vehicles. In the figure, the output shaft of the AMT gearbox 31 and the output shaft of the motor 32 are connected through a torque coupler (not shown), and the power of the torque coupler output shaft is transmitted to the left front wheel 24 and the left front wheel through the final drive 30 and the half shaft. Right front w...

Abstract

The invention relates to a regenerative brake and hydraulic locking-proof integrated control system of a hybrid vehicle. This integrated control system includes regenerative brake control subsystem and hydraulic braking control subsystem. Two control subsystems are not only independently mutual but also unified each other.Independently is that the hydraulic pressure is controlled by the hydraulic braking control subsystem according to the on-position of wheel without restriction of regenerative brake control subsystem operating status, in the like manner, the regenerative brake moment of front axle is also controlled by regenerative brake control subsystem according to the on-position of wheel without restriction of hydraulic control subsystem operating status. Unification of the two brake control subsystems is that the two control subsystems are coordinating and unifying on acting effect, which can realize harmonious unification on energy recovery and locking prevention. The regenerative brake function of the performance motor of high limit on guaranteeing automobile braking safety and smooth-going nature basis has mainly been solved in the invention, which improves the capacity usage ratio and the economy of car load.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular to a regenerative braking and anti-lock braking integrated control system. Background technique [0002] The patent novelty search shows that the following five patents are related to the present invention. [0003] One is the "vehicle brake control system" of Nissan Automobile Co., Ltd., and the patent application number is 200320128501. The braking control system involved in this patent mainly has a braking mode selection part. Different braking methods have different control method priorities. [0004] The second is the "Control Method for Improving Braking Energy Recovery of Hybrid Electric Vehicles" by China FAW Group Corporation, the application number is 200510016977. This patent only controls the clutch to disconnect the engine from the drive train through the vehicle controller when the accelerator pedal is closed, and at the same time instructs the moto...
