Abstract: A transmission control method is provided to reliably perform a speed shifting process even at a harsh driving mode by accurately recognizing torque maps at D and R speeds. During a backward driving, a torque, which is smaller than a D speed driving, is applied on a vehicle. Right after a speed shifting from P speed to an R speed and a speed shifting to the R speed, an operation delay time is applied on the vehicle. The operation delay time is synchronized with an inhibit switch, such that a torque map for the R speed is recognized. Whether an inhibit switch manipulation signal is received is determined. When the inhibit switch manipulation signal is received, the torque map for the R speed is used, while the smaller torque is applied on the vehicle.

Abstract: PURPOSE: A target angular control method for an electronic throttle system of an engine is provided to improve fuel consumption ratio and to prevent exhaust from being generated by preventing dual acceleration and acceleration delay when a vehicle is traveled. CONSTITUTION: When power is applied to a vehicle, all parameters are initialized(S100). Then, it is determined whether the vehicle is in an acceleration mode. If the vehicle is in the acceleration mode, a variation of an angular degree of an accelerator pedal is corrected by applying first and second tailing coefficient. A final target angular degree of an engine throttle is calculated based on the variation of the angular degree of the accelerator pedal and a variation of an idle speed actuator(S140). After that, an electronic throttle driving control signal is generated based on the calculated final target angular degree of the engine throttle.
