Problems solved by technology
The electro-hydraulic braking systems currently on the market use incomplete decoupling schemes in order to meet the regulatory requirements for manpower backup, and most of them only achieve complete decoupling at small decelerations. The efficiency of recycling is maximized, which is also one of the bottlenecks limiting the improvement of cruising range

The invention discloses a brake boosting system and a control method thereof. The brake boosting system comprises an electro-hydraulic brake system, a brake pedal, a two-position three-way electromagnetic valve, an energy accumulator, a first shuttle valve, a second shuttle valve, an ABS / ESC electromagnetic valve and a brake wheel cylinder. The brake pedal is connected with a first main cylinder; two brake circuits output by the first main cylinder are respectively connected with an inlet of the two-position three-way electromagnetic valve, and the energy accumulator is connected with an outlet of the two-position three-way electromagnetic valve; the electro-hydraulic braking system is connected with the second main cylinder; two oil outlets of the second main cylinder are respectively connected with oil inlets at one ends of the first shuttle valve and the second shuttle valve; oil inlets at the other ends of the first shuttle valve and the second shuttle valve are respectively connected with two brake circuits output by a first main cylinder; oil outlets of the first shuttle valve and the second shuttle valve are connected with an oil inlet of the ABS / ESC electromagnetic valve, and an oil outlet of the ABS / ESC electromagnetic valve is connected with the brake wheel cylinder. According to the invention, manpower backup braking and power-assisted braking can be realized, and the braking energy recovery efficiency of the vehicle is improved.
Description
technical field [0001] The invention relates to an automobile brake system, in particular to a booster brake system and a control method thereof. Background technique [0002] Automobile braking system is closely related to automobile driving safety. In recent years, with the continuous development of pure electric vehicle technology, the requirements for the cruising range of pure electric vehicles have become higher and higher. One of the important technical means to improve the cruising range is to improve the efficiency of braking energy recovery. The electro-hydraulic braking systems currently on the market use incomplete decoupling schemes in order to meet the regulatory requirements for manpower backup, and most of them only achieve complete decoupling at small decelerations. The efficiency of recovery is maximized, which is also one of the bottlenecks limiting the improvement of cruising range. Contents of the invention [0003] The primary purpose of the present...
