Vehicle steering and tailboard lifting control system and control method

The invention relates to a vehicle steering and tailboard lifting control system and method, and the control system comprises a steering oil pump which communicates with a chassis steering engine and a tailboard control device; the control switch assembly is installed on the steering oil pump, and the control switch assembly can be switched between the communication between the steering oil pump and the chassis steering engine and the communication between the steering oil pump and the tail plate control device; and the vehicle control unit is used for receiving the braking information of the brake assembly and enabling the steering oil pump to supply oil to the chassis steering engine or the tail plate control device according to the braking information. An electric high-pressure steering oil pump and an oil system in a chassis steering system are used for replacing a low-pressure oil pump in the whole vehicle hydraulic tail plate operation process, the chassis high-pressure electric steering oil pump is mad
