Abstract:
1. A method for determining whether a motor vehicle transmission that is connected to an engine via a clutch that is actuated by a clutch actuator has been shifted into a neutral gear when the vehicle is at rest with a disengaged clutch, said method comprising the steps of: a) engaging the clutch from its disengaged position to a predetermined extent, b) determining engine rotational speed during engagement of the clutch, c) interpreting an engine rotational speed reduction as a transmission that is not in neutral and renewing disengagement of the clutch, and d) interpreting an absence of an engine rotational speed reduction as a transmission that is in neutral, and e) repeating steps a) through d) continuously and after each step d) displacing a gearshift component of the transmission by a predetermined amount until step d) has been satisfied.
