<p>PURPOSE:To prevent abrupt start and shocks upon engagement, by setting an upper limit to the ascent grade of transmission torque to carry out the slip control of a start clutch even though an abnormally high input rotational speed signal is inputted due to noise in a signal system. CONSTITUTION:Signals from sensors 61 through 64 are inputted to an input interface 66, and a throttle opening degree signal from a sensor 65 is converted into a digital signal by an A/D converter 67. A CPU 68, a ROM 69, a RAM 70, an output interface 71, the input interface 66 and the A/D converter 67 are coupled to each other through a bus 71. The output of the output interface 71 is delivered as a duty control signal for a pulley control solenoid 44 and a start control solenoid 46, through an output driver 73. Further, when the slip control of a start clutch is carried out, an upper limit is set to the ascent grade of transmission torque to prevent occurrence of shocks upon engagement even through an abnormally high input rotational speed signal is inputted due to noise in the signal system.</p> |
