<p>PURPOSE:To enlarge the utilization range of a creep by controlling a transmission torque based on a specified mode signal through an operation mode setting means, controlling a creep rate, and thereby selecting strength of the creep according to operation conditions. CONSTITUTION:A transmission torque control means is composed of a hydraulic clutch 62 and an oil passage 64. An operation mode setting means serves as a switch which generates a snow mode signal. A creep control means is composed of a clutch pressure control valve 52, a three-directional solenoid valve 58, a pressure sensor 68, an electronic control part 98. The electronic control part 98 performs controlling so as to obtain a selected target transmission torque based on the snow mode signal from the switch which selects one among a plurality of target transmission torque. The target transmission torque serves as a function of an engine speed, at least, and a creep stronger than normal one can be selected. A driver can select strength of the creep according to a driving condition, so that starting operation is facilitated on a slipping or snowy road surface.</p> |
