Control system and control method of AMT power takeoff

Abstract

Disclosed is a control system of an AMT power takeoff. The control system of the AMT power takeoff comprises an automatic gearbox. The automatic gearbox is provided with an AMT control unit. A middleshaft of the automatic gearbox is provided with a power takeoff body. The power takeoff body is provided with a position switch and a power takeoff clutch. The AMT control unit is in signal connectionwith an instrument, a power takeoff switch, a power takeoff solenoid valve, a clutch, an engine control unit, a shift handle and a position switch. One end of the clutch is connected with an engine mechanically. The engine is in signal connection with the engine control unit. The other end of the clutch is connected with the automatic gearbox mechanically. The power takeoff clutch is connected with one end of the power takeoff solenoid valve in a gas rode mode. The other end of the power takeoff solenoid valve is connected with a whole vehicle gas source in a gas road mode. The power takeoffbody is mechanically connected with a power takeoff device through a transmission shaft. According to the design of the control system of the AMT power takeoff, shift function can not only be achievedduring driving power takeoff, but also braking and driving power takeoff of a traditional mechanical gearbox can be achieved, operation is simple, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of automobile gearboxes, in particular to an AMT power take-off control system and a control method thereof, which are mainly suitable for realizing the shifting function when power is taken off while driving. Background technique [0002] The existing mechanical transmission power take-off control technical scheme is as follows: the driver controls the power take-off button of the power take-off, directly controls the work of the solenoid valve of the power take-off, and the power take-off is put into gear; the operation is simple, and the driver needs to judge the power take-off Whether the gear is engaged and whether it is working normally. However, for the automatic mechanical transmission (AMT), due to the cancellation of the clutch pedal, the traditional power take-off control method cannot be realized in the AMT system, so it is necessary to optimize and improve the technical scheme and control method...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects and problems in the prior art that the gear shifting function cannot be realized and the operation is complicated when the driving power is taken off, and to provide an AMT power take-off control that can realize the gear shifting function and is simple to operate when driving the power taking off System and its control method
