PROBLEM TO BE SOLVED: To generate accurate and stable input by preventing influence of fluctuation of the sensor output caused by pulse signals impressed on a linear solenoid. SOLUTION: This control device of a transmission is composed of a sensor 1 to sense the input signal for a vehicle, an input processing part 2 to convert the analog signal given by the sensor 1 into a digital signal, an oil pressure calculation part 3 to calculate the oil pressure for linear solenoid, a PWM calculation part 4 to calculate the PWM output of the current to achieve the oil pressure according to the calculation in the part 3, and a linear solenoid to perform gear shift in compliance with the PWM output. A task schedule means 6 is furnished to make sampling of the output value within the range in which the analog signals from the sensor 1 are stabilized, on the basis of the timing of the emitted pulse signals. |
