Zusammenfassung: | The invention relates to a one-key parking power take-off control method for a special vehicle. The problem that a power source cannot be provided for large-torque equipment in an existing method is solved. The control system comprises a one-button operation switch K1, a transfer case neutral position electromagnetic valve C1, a power takeoff electromagnetic valve C2, a pressure switch Y1, an engine electric control unit, a power takeoff control unit and a gearbox electric control unit, the transfer case neutral position electromagnetic valve C1 and the power takeoff electromagnetic valve C2 can be connected and disconnected through the one-button operation switch K1, and the power takeoff control unit and the gearbox electric control unit can be connected and disconnected through the pressure switch Y1. The engine electric control unit, the power take-off control unit and the gearbox electric control unit are all connected to the CAN bus. By the adoption of the gearbox, the output transmission ratio can be c |
