BRAKING SYSTEM FOR A HYBRID VEHICLE PREVENTING THE TIGHTENING OF SKATES IN ENERGY RECOVERY MODE

摘要

Hybrid vehicle braking system comprising wheel brakes (14, 18) each connected to a pressure accumulator (24) having a low accumulation pressure, by a load-relieving solenoid valve (20, 22) which is open during braking moderated in order to limit the pressure in these brakes at the low accumulation pressure to allow energy recovery by traction machines using auxiliary energy, characterized in that it comprises means blocking the hydraulic pressure delivered to the brakes ( 44), as long as the control pressure of these brakes is below a trigger threshold higher than the low pressure of the accumulator (24).
