The present invention discloses a forklift active braking control method based on power shift transmission, comprising the following steps: step 1: obtaining forklift state parameters, if the current state of the forklift is an active braking state, performing step 2; step 2: inputting a current speed signal of the forklift, and obtaining duty ratio parameters that are impact-free and can produce a maximum braking force at the current speed, and outputting proportional solenoid valve control parameters of the transmission according to the obtained duty ratio parameters; step 3: using the proportional solenoid valve control parameters to control the proportional solenoid valve of the transmission to take action, and controlling the forklift power system to output a driving force opposite to a current movement direction of the forklift to drive the forklift to actively brake; step 4: exiting the active braking of the forklift when the forklift speed is detected to be zero. The active safe braking function is realized through clutch active braking, which can reduce the wear and tear of the original braking system of the vehicle and extend its service life. The vehicle clutch adopts a wet clutch, which has excellent heat dissipation effect, long service life and easy replacement.
