Abstract

PURPOSE:To absorb the dispersion of an individual vehicle and the change through the lapse of time by correcting the standard operation quantity to the direction for reducing the output of an integrator, through the learning control, in a PID operating means for correcting the difference between the actual value of the engine revolution speed and an aimed value. CONSTITUTION:A PID operating means 81 is equipped with an integrator 82, proportional device 83, and differentiator 84, and speed-change-controls a continuously variable transmission (CVT)10 through a control valve 43 by the output signal, and the actual engine revolution speed is feedback-controlled to an aimed engine revolution speed. In this case, a means 85 determines a standard operation quantity corresponding to the operation signal, and this standard operation quantity is added with the output of the PID operating means 81, and the result is inputted into the control valve 43. While, the learning instruction signal and the reset signal for clearing the integrator 82 are outputted by a means 86 at each interval of set time in the stationary operation state. The controller is operated in interlocking with the learning instruction signal, and a means 87 corrects the standard operation quantity towards reduction by using the output of the integrator 2.
