Abstract

The invention relates to an automatic transmission control apparatus including an engine generating power by a combustion of fuel; an automatic transmission provided with a friction element including a clutch and a brake and changing the power generated in the engine into a torque required depending on a speed by an engagement and release of the friction element to be output; an accelerator pedal position sensor detecting a position signal of the accelerator pedal; and a controller determining whether a vehicle is in a rapid acceleration state from the position signal of the accelerator pedal detected from the accelerator pedal position sensor and correcting a control hydraulic pressure of the friction element if the vehicle is the rapid acceleration state. Since the friction element control hydraulic pressure is controlled depending on the operation speed of the accelerator pedal, the shift responsiveness may 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...
