Control system and control method of all-terrain crawler-type emergency drainage vehicle

The invention relates to a control system and a control method of an all-terrain crawler-type emergency flood drainage vehicle, the control system and the control method provided by the invention have four working modes, including normal land running, simultaneous double-water-pump operation and two single-water-pump working modes, and the running speed of an engine can be adjusted by operating an accelerator pedal, so that the running speed of the vehicle can be adjusted. The flow of the power hydraulic pump is changed, different running speeds of the vehicle and different output flows of the water pump are achieved, the problems that an existing universal flood drainage vehicle is large in flood drainage operation space, long in unfolding time, complex in control, single in operation mode and incapable of freely controlling the flow of the water pump are solved, and the vehicle can be used in various environments such as urban waterlogging and rescue and relief work.
