摘要： A system to control the operation of a vehicular transmission embodying the concepts of the present invention utilizes a controller, at least one pulse width modulation solenoid valve and a torque transfer device operatively controlled by each of the solenoid valves so as to regulate a transmission system. The controller operatively imposes not only a varying modulation frequency on each of the solenoid valves, but also a varying modulation duty cycle on each of the solenoid valves. The controller also operatively varies the modulation rate of said frequency and said duty cycle of the fluid pressure operating the plurality of torque transfer devices, thus controlling the operation of each solenoid valve such that it does not impose a torque spike on the operation of the transmission as each solenoid valve applies fluid pressure to the appropriate torque transfer device. Accordingly, the controller provides smooth and quiet operation of the transmission.
