Closed-loop control method and equipment for parking power takeoff of off-road vehicle

The invention provides a closed-loop control method and equipment for a parking power takeoff of an off-road vehicle. The method comprises the steps that if a power takeoff switch is closed, the working state of the power takeoff is judged; if the power takeoff is in the slowdown state, the rotating speed of the engine is smaller than or equal to the first rotating speed threshold value, the vehicle speed is zero, and the gear of the gearbox is neutral; if the parking braking signal is closed, the power takeoff is controlled to be connected, and the delay duration is equal to a first duration threshold value; and if the state of the power takeoff is the combined state, parking power takeoff is started, the parking power takeoff state is sent to the intelligent information terminal, and the engine enters the parking power takeoff state. According to the parking power takeoff control system, the control defects of an existing parking power takeoff can be overcome, power takeoff damage caused by manual misoperat
