Embodiment Construction

[0026] Referring to FIG. 1 , an automatic gear shift 1 (also called "mechanical gear shift") of a car. The engine 2 is an internal combustion engine, the output shaft 4 is connected by an insert clutch 5, the transmission gear 7 is connected to the input shaft 6 and an output shaft 8, which interacts by transmission with the wheels (not shown). The clutch 5 is connected with the first transmission unit 10, and the first transmission unit 10 includes a power unit 10a that receives an open / close drive signal to engage or disengage the clutch. The transmission unit 10 performs hydraulic transmission through pressure oil, so as to engage and disengage the clutch 5 . The transmission gear 7 is connected with the second transmission unit 12, and the second transmission unit 12 includes a power unit 12a. The power unit receives a selection drive signal to select a gear position, and receives an engagement / disengagement command signal to perform a gear-in / disengagement operation on t...

Abstract

This invention relates to the car shift; it is for the automatic transmission of the car. This invention publishes a kind of method for controlling the automatic transmission of the autocar, it includes the automatic performance model,the manual manipulation model, its character is that the automatic performance model contains a superimposing modular which can accept the manually operation that form the manual manipulation model, the automatic performance model can executes the manually operation through the modular signal, modifies the drive ratio of the automatic device, and executes the automatic transmission which is accordant with the manually operation. The invention is accurate,shortcut, and its structure is simple, the command is handy.

Description

technical field [0001] The invention relates to automobile gear shifting, in particular to the automobile automatic shifting technology. Background technique [0002] The automatic shifting of the vehicle is realized by sending signals from the electronic control unit to control multiple transmission devices (such as: hydraulic control). These transmission devices are connected with transmission gears and clutches to perform gear selection and gear-on / off operations, as well as clutch engagement and separation. In the existing control method for automatic gear shifting of automobiles, there are two modes: automatic operation mode and manual operation mode. These two modes of operation are independent of each other, and the driver selects the desired mode of operation through commands. In automatic mode of operation, the control unit receives as input a set of data signals (vehicle speed, accelerator pedal position, rpm, engine torque, etc.). After processing these data, t...
