The invention discloses a vehicle cargo compartment lifting system and a vehicle cargo compartment lifting method.The vehicle cargo compartment lifting system comprises a lifting pump, a pilot oil supply valve, a hydraulic control lifting valve, a lifting oil cylinder, a lifting handle and a controller, the pilot oil supply valve comprises a first proportional electromagnetic valve and a second proportional electromagnetic valve, the hydraulic control lifting valve comprises a main valve, the main valve is a proportional reversing valve, and the lifting oil cylinder is connected with the hydraulic control lifting valve; an oil outlet of the lifting pump is connected to the main valve, the lifting pump is connected to the first proportional electromagnetic valve and the second proportional electromagnetic valve, the first proportional electromagnetic valve and the second proportional electromagnetic valve are connected to the main valve, and the lifting oil cylinder is connected to the main valve. The controller is used for sending proportional current signals to the first proportional electromagnetic valve and the second proportional electromagnetic valve according to a linear control instruction received by the lifting handle, and then pilot oil is output to the main valve to control the state of the main valve. According to the technical scheme, the opening degree can be proportionally adjusted through the main valve, so that the lifting speed of the lifting oil cylinder is controlled, and accurate control over lifting and descending of a vehicle cargo compartment is achieved.
