Solenoid plunger correction control apparatus of automatic transmission on vehicle and method thereof

As to controlling the solenoid to the most central to the oil pressure control in an automatic transmission the movement of the plunger to linearize the non-linear correcting control intervals on the solenoid plunger movement that appear in some areas to match the target value, Determining a target gear position from a shift schedule map table to detect the various information of the vehicle during traveling, and the control duty in the target speed change calculating a control duty for the stage engages with the calculated the controlled area in which the duty is given the solenoid characteristics value if the determining process and, when the characteristics of the solenoid control duty value in that given area voltage and the oil temperature is set, unless the steps of: determining whether satisfies the condition satisfying the condition that the voltage and the oil temperature is set at the control duty cycle correction that without performing the control, the voltage to the process for oil temperature to extract the solenoid of the excitation time in accordance with the state when control duty is satisfied the predetermined condition and, and by applying the calculated and woman map table value in the time of the actual drive It extracts the excitation time drives the solenoid to provide a linearity in the actual movement of the plunger It comprises the step of matching the target value.
