Abstract

The invention discloses an electrically controlled brake power-assisted system and relates to the field of vehicle brake systems. The electrically controlled brake power-assisted system comprises a pedal simulator, an electronic control unit, a driving motor and a power-assisted brake cylinder, wherein the pedal simulator is constructed to be integrated together with a brake master cylinder, and apedal simulator cylinder body serves as a piston of the brake master cylinder; an output end of the driving motor is connected with a planet gear reducing mechanism, and the planet gear reducing mechanism is connected with the power-assisted brake cylinder through racks; and in a normal brake work mode, the pedal simulator absorbs the stroke of a brake pedal push rod, the electronic control unitsends an operating instruction to the driving motor according to the stroke of the pedal push rod, and the planet gear reducing mechanism is matched with the racks to drive the piston of the power-assisted brake cylinder to generate brake pressure, thereby realizing the brake of a vehicle.

Description

technical field [0001] The present invention relates to the field of vehicle brake systems, in particular to an electronically controlled brake booster system for automobiles, which is applicable to various types of motor vehicles, including new energy vehicles such as hybrid electric vehicles; Vehicle braking system that controls the brake assist system. Background technique [0002] With the breakthrough of new energy vehicle technology, compared with traditional fuel vehicles, the specific advantages of new energy vehicles are becoming more and more obvious, and the share of new energy vehicles is also increasing year by year. Due to the substantial difference in power drive between new energy vehicles and traditional fuel vehicles, some structures or components that can be used on traditional fuel vehicles are not suitable for new energy vehicles. [0003] For example, in the field of automotive braking, traditional fuel vehicles use a vacuum booster for brake boosting,...
