Abstract

The invention discloses a hybrid vehicle brake vacuum booster system and its control method. The system is composed of a brake vacuum booster assembly, an engine and a power assembly. The brake vacuum booster assembly includes a brake vacuum booster, an electric vacuum pump, The pipelines are connected between the two, the power assembly is connected with the engine transmission, and the intake manifold inside the engine is respectively connected with the brake vacuum booster and the electric vacuum pump pipeline through a three-way solenoid valve. The invention can not only meet the conventional brake boosting requirements during vehicle driving, but also can immediately establish brake vacuum boosting in the event of a brake vacuum boosting system failure or continuous braking, thereby greatly improving braking safety and ensuring Vehicle braking performance.

Description

technical field [0001] The invention relates to a vehicle brake vacuum booster system and a control method thereof, in particular to a hybrid vehicle, especially a brake vacuum booster system and a control method of a range-extended vehicle, and belongs to the technical field of vehicle control. Background technique [0002] In recent years, with the deteriorating environment worldwide and the increasingly tense energy supply, the tightening of fuel emission regulations around the world has become an irreversible trend. In such an era background, hybrid vehicles have gradually become a focus of automobile research and development due to their energy-saving and low-emission characteristics, and various research work on hybrid vehicles is also being carried out in an orderly manner. [0003] Specifically, an electric brake vacuum booster pump is generally used in the existing brake vacuum booster system of a hybrid vehicle as the driver's brake booster to reduce the "labor int...
