Vehicle composite braking system based on hydraulic braking and electronic mechanical braking

The utility model belongs to the technical field of automobile braking systems, and particularly relates to a vehicle composite braking system based on hydraulic braking and electronic mechanical braking. The system with the conventional hydraulic braking adopted by front wheels and the electronic mechanical braking adopted by rear wheels is provided. The vehicle composite braking system is characterized by comprising a braking pedal (15), a braking pedal displacement sensor (16), a liquid storage tank (17), a single-cavity braking master cylinder (18), a pressure regulator (19), a front wheel speed sensor (20), a first braking wheel cylinder (21), a second braking wheel cylinder (22), a rear wheel speed sensor (23), a power supply (24), a central control module (25), an EMB execution motor controller (26) and an EMB brake (27). The conventional hydraulic braking is adopted by the front wheels, the electronic mechanical braking is adopted by the rear wheels, and the possible reliability problem and possible potential safety hazards due to the fact that EMB braking is adopted by the front wheels and the rear wheels are effectively solved.
