The invention discloses a brake circuit type adjustable vehicle electro-hydraulic brake system. The system belongs to the technical field of automobile braking and comprises an automobile conventional electro-hydraulic braking system and an automobile backup braking system. The vehicle conventional electro-hydraulic braking system comprises a left hydraulic pump, a right hydraulic pump, an energy accumulator, a motor, an electromagnetic valve, a brake wheel cylinder, a left overflow valve, a right overflow valve, a hydraulic motor, a generator, a loop type selection switch, a liquid storage tank and the like. The vehicle backup brake system comprises an electromagnetic valve, a pedal travel simulator, a load sensing proportional valve, a brake master cylinder, a brake wheel cylinder, a push rod, a brake pedal arm, a liquid storage tank and the like. According to the invention, the brake loop type is timely switched through the loop type selection switch, and the advantages of X-type, H-type and B-type vehicle brake loops are fully utilized; when the conventional electro-hydraulic braking system of the vehicle fails, the backup braking system of the vehicle provides normal braking capacity; the design mode that the storage battery and the standby power supply respectively supply power to the electromagnetic valves in the two braking systems is adopted, and the service braking reliability is improved.
