The invention provides a brake-by-wire system for automobile braking. The system comprises a brake-by-wire assembly, a pedal input assembly, an oil can, a pedal simulator assembly, a servo cylinder assembly, a motor used for driving the servo cylinder assembly and a main control unit are integrated on the brake-by-wire assembly, and a liquid outlet hole is formed in the brake-by-wire assembly. Anelectromagnetic valve assembly used for switching pressure oil output by the servo cylinder assembly or pressure oil output by the pedal input assembly to be output from the liquid outlet hole is arranged in the brake-by-wire assembly in an integrated mode, and the liquid outlet hole of the brake-by-wire assembly is communicated with an anti-lock braking system or an automobile body stabilizing system through a pipeline. And the anti-lock braking system or the automobile body stabilizing system is connected with wheel calipers. The system is simple in structure, the automobile brake performance can be improved, an ABS product, an ESP product and a production line can be continuously utilized, and meanwhile the endurance mileage of a hybrid electric vehicle and a pure electric vehicle is indirectly prolonged through the energy recovery function of a brake-by-wire product.
Description
technical field [0001] The invention relates to the field of automobile brake systems, in particular to a brake-by-wire brake system for automobile brakes. Background technique [0002] The brake system is one of the essential modules of the vehicle. Due to the shortcomings of traditional vacuum booster products such as large volume, heavy weight, complicated assembly, easy leakage of vacuum source, poor boosting performance in high altitude areas, and inability to achieve energy recovery on hybrid and electric vehicles, based on the above shortcomings and market demand , In recent years, technical solutions and products of remote control products have emerged as the times require. Compared with vacuum boosters, brake-by-wire products have the following advantages: high integration, small size, light weight, product performance does not change significantly with the external environment pressure, temperature, etc., applicable to traditional fuel vehicles, hybrid vehicles, p...
