| description | The invention relates to a forklift hydraulic pump motor rotating speed control method and device and a forklift. The control method comprises the following steps that S1, a timer is arranged, and the timer executes a set timing period; s2, executing rotating speed control logic: setting the rotating speed of a hydraulic pump motor according to the received information of the vehicle speed, the steering information, the hydraulic operation information and the actual hydraulic required rotating speed in a manner at least that when the vehicle speed is 0 and the duration of no steering operation and no hydraulic operation exceeds the timing period, the rotating speed of the hydraulic pump motor is controlled; the rotating speed of the hydraulic pump motor is set to be 0. The steering requirement of forklift traveling can be met, the flow requirements of low-speed traveling, high-speed traveling and hydraulic acting are considered, energy consumption can be reduced, and driving safety can be improved.
