Abstract
In a motor vehicle with a manually-controlled gearbox (4) and an automatically-operated clutch (3) which is disengaged when a sensor device (14) detects a manual activation of the gear shift lever (13), the clutch is not disengaged unless the engine torque is less than a boundary value in order to avoid engine flare. The boundary value is a variable dependent on the rate of release of the accelerator pedal, to allow for a delay in the reduction of torque when the accelerator depression is reduced. The torque is calculated from the accelerator or throttle position as well as other parameters.
