    摘要: The invention relates to a vehicle hydraulic assistance method comprising: two hydraulic devices connected therebetween by a supply line, a return line, a power boost source, and a tank, the power boost source being connected to the supply line and return line via a power boost line and taking the oil from the tank; and a vacuum valve including an input port, connected to the supply line and return line, and an output port connected to the tank. The vacuum valve has a first passing state and a second blocking state. The method includes the steps of: (E1) activating the power boost source when the vehicle fulfills at least one predetermined requirement, the vacuum valve being in the first passing state; and (E2) switching the vacuum valve from the first passing state to the second blocking state when hydraulic assistance is required, thus making it possible to boost power to the supply system and return system.
