Control method for AMT (automated mechanical transmission) power takeoff unit

Abstract

The invention relates to the technical field of automobiles, particularly to a control method for an AMT (automated mechanical transmission) power takeoff unit. The invention aims to provide the control method, a driver only needs to press a power takeoff button of the power takeoff unit, put into a gear or step on an accelerator according to the prompt of a display, the purpose of taking off power can be realized. The processes of putting into the gear and picking the gear for the power takeoff unit are simple and convenient, the structure is simple and reasonable, a control flow is clear, and the operation and the control are convenient. The method is characterized by comprising the following steps that a switch of the power takeoff unit is controlled, so that a signal is input into an AMT control unit; the AMT control unit controls an electromagnetic valve of the power takeoff unit, a range gear electromagnetic valve and a clutch, so that a piston on a cylinder of the power takeoff unit movably controls a position switch of the power takeoff unit; the position switch of the power takeoff unit transmits a state signal of the power takeoff unit to the AMT control unit; and the AMT control unit transmits a prompt signal to the display to prompt the driver for operation.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an AMT power take-off control method. Background technique [0002] The power take-off is one or more sets of variable speed gears, also known as the power output device, which is generally composed of a gearbox, a clutch, and a controller. It is connected to the input shaft of the force device, which is a separate gear in the gearbox. When this gear is engaged, the lift pump can run as soon as the gas is added. As the most economical and convenient power source for special-purpose vehicles, power take-offs are the first choice for various special-purpose vehicles. At present, domestic AMT is still in its infancy, and there are almost no vehicles equipped with AMT power take-offs. Some special-purpose vehicles are installed AMT power take-off is installed, and for special vehicles equipped with AMT power take-off, it is necessary to develop a new AMT power take-off control m...
