Abstract

The invention discloses an AMT rear auxiliary box power take-off control system and a control method thereof, and belongs to the field of vehicle power take-off. According to the AMT rear auxiliary box power take-off control system, information interaction is carried out among the VCU, the TCU and the instrument. The interaction between the VCU and the TCU is closed-loop control and the system security is improved; the VCU (vehicle control unit ) is responsible for power take-off condition inspection, power take-off request sending, power take-off control and power take-off exception handling,the TCU is responsible for power take-off condition secondary confirmation, transmission gear and clutch control and gear exception handling in the power take-off process, and the instrument is responsible for state display and driver interaction. According to the system, the whole vehicle is rarely changed, the rear auxiliary box power takeoff device is controlled by the VCU, the requirements for TCU driving power, pin resources and the like are greatly reduced, so that the cost of the whole vehicle and a transmission is greatly reduced. According to the AMT rear auxiliary box power take-offcontrol method, power take-off is safe and reliable.

Description

technical field [0001] The invention belongs to the field of vehicle power take-off, in particular to an AMT rear auxiliary box power take-off control system and a control method thereof. Background technique [0002] At present, there are very few technologies for AMT to match the power take-off, and most of them are technical solutions for power take-off through the intermediate shaft. When the power is taken through the intermediate shaft, the transmission is in neutral, so the power take-off speed ratio cannot be changed. Most of the vehicles that match the manual gearbox adopt the power take-off scheme of the rear auxiliary box, and the transmission is in the gear state when the power is taken off. [0003] In recent years, with the increasing demand for vehicle automation in the market, some OEMs have begun to match AMT with power take-off to upgrade the original manual transmission. Since the vast majority of manual transmissions adopt the power take-off scheme of th...
