The braking system for a hybrid vehicle preventing the tightening of the shoes in the embodiment of the energy recovery

摘要

A braking system for a hybrid vehicle comprising wheel brakes (14, 18) each linked to a pressure accumulator (24) having a low accumulation pressure, by a solenoid relief valve (20, 22) that is open during moderate braking in order to limit the pressure in said brakes to the low accumulation pressure in order to allow energy recovery by traction machines using an auxiliary energy, characterised in that it comprises means blocking the hydraulic pressure delivered to the brakes (44), as long as the control pressure of said brakes is lower than a trigger threshold higher than the low pressure of the accumulator (24).
