Abstract

A sensing unit of the throttle valve which detects an opening amount of the throttle valve linked to the acceleration pedal and outputs an electrical signal corresponding thereto; A tilt and curve detector configured to detect a tilt state and a curved state of the driving road and output an electrical signal corresponding thereto; A driving speed detection unit for detecting a current driving speed of the vehicle and a driving speed of the vehicle and outputting an electric signal corresponding thereto; When the power is applied, it detects the state of the driving road and the vehicle speed of the current driving vehicle, and the driver wants to accelerate or decelerate, when the current driving road is uphill, downhill or curve road, and the current vehicle is running above the set speed. In this case, the shift pattern control apparatus of the automatic transmission comprising an automatic transmission execution apparatus which directly influences the state of the vehicle under the control of the shift pattern by the shift control unit for shifting the shift pattern to the position most suitable for the driver's will, per hour As a result of integrating the throttle operation state, and searching and comparing the value, it is possible to accurately determine the driving intention of the driver, and to control the shift to the corresponding target shift stage more quickly than the conventional shift pattern control method. To improve the responsiveness of the movements and improve the running performance of the vehicle. It may provide a shift pattern control device and method of an automatic transmission.
