<p>PURPOSE:To make clutch engagement corresponding to the grip force between a road surface and a tire as well as to prevent a wheel spin from occurring, by controlling a clutch so as to be engaged with a speed in response to the speed-up rate of a driven wheel at the time of the clutch engagement when starting. CONSTITUTION:In case of a device which transmits the torque of an engine B to a driving wheel by engagement of a clutch A, a speed-up rate detecting part E, detecting a speed-up rate at the initial stage of a rotation start in a driven wheel, is installed in a control part G. Also there is provided with a clutch engaging speed setting part F which sets a clutch engaging speed in response to this speed-up rate. And, and it is constituted so as to control the engagement of the clutch A so as to engage the clutch A at the engaging speed set by the setting part F via a clutch engagement checking device D. With this constitution, the clutch engagement corresponding to group force is made performable so that a wheel spin at starting is preventable from occurring before it happens.</p> |
