Automobile electric control hydraulic braking system and energy recycling method thereof

Abstract

The invention discloses an automobile electric control hydraulic braking system and an energy recycling method thereof. The automobile electric control hydraulic braking system comprises an electric control hydraulic braking module and an energy supplying module. The electric control hydraulic braking module comprises a pedal simulator, an electric control unit, a high-pressure energy accumulator, a hydraulic pump, an oil cup and a hydraulic control unit. The energy supplying module comprises a transmission device and a clutch device. The electric control unit controls the states of oil inlet / outlet electromagnetic valves of the hydraulic control unit according to induction signals of the pedal simulator and pressure signals of a braking wheel cylinder and controls the state of the clutch device according to rotating speed signals of wheels and pressure signals of the high-pressure energy accumulator. When the clutch device is combined, the wheels are mechanically connected with the transmission device to drive the hydraulic pump to work, hydraulic oil in the oil cup is stored in the high-pressure energy accumulator. When the clutch device is separated, mechanical connection between the wheels and the transmission device is disconnected. Intelligent automobile braking and braking energy recycling can be achieved.
