Embodiment Construction

[0030] The following description is merely exemplary in nature and is not intended to limit the invention, application or use. It should be understood that throughout the sets of drawings, corresponding reference characters indicate like or corresponding parts and features.

[0031] figure 1 is a block diagram of a configuration of an automatic transmission control device according to one form of the present invention.

[0032] Such as figure 1 As shown, an automatic transmission control device according to one form of the present invention includes an engine 20 generating power; an automatic transmission 40 provided with friction elements, the automatic transmission 40 includes a clutch 41 and a brake 43, and according to the speed to be output, by Engagement and release of the friction elements change the power generated in the engine into required torque; the accelerator pedal position sensor 10 (APS) detects the position signal of the accelerator pedal; and the control...

Abstract

The present invention relates to an automatic transmission control device, which includes an engine generating power by combustion of fuel; an automatic transmission provided with friction elements, which includes clutches and brakes, and according to the speed to be output by the engagement and release of the friction elements, the The power generated in the engine is changed into the required torque; the accelerator pedal position sensor, which detects the position signal of the accelerator pedal; and the controller, which determines whether the vehicle is in the rapid Acceleration state, and if the vehicle is in a rapid acceleration state, correct the control hydraulic pressure of the friction element. Since the hydraulic pressure of the friction element is controlled according to the operation speed of the accelerator pedal, shift response can be improved.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2015-0113993 filed on Aug. 12, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to a device for controlling an automatic transmission and a method thereof. Background technique [0004] The statements in this section merely provide background information related to the present invention and may not constitute prior art. [0005] Generally, a vehicle is equipped with a transmission that receives power generated by an engine to control a driving speed of the vehicle. Transmissions can be classified into manual transmissions controlled by the driver and automatic transmissions that are automatically controlled based on the driving speed of the vehicle. [0006] Based on the driving speed of the vehicle, the opening value of the throttle valve, and general detection cond...
