Abstract
A method for driving a braking circuit for a vehicle equipped with a coupling is disclosed. The vehicle incudes a hydraulic supply circuit and a hydraulic control circuit equipped with a driving device. The coupling includes a hydraulic braking circuit linked to the hydraulic supply circuit and to the hydraulic control circuit and includes a hydraulic accumulator. When the vehicle is stopped and the pressure inside the hydraulic accumulator is less than or equal to a threshold pressure value, the driving deice increases the pressure of the hydraulic accumulator via the hydraulic control circuit.
