Abstract

A system is described for automatically locking the doors of a vehicle equipped with electric power locks, wherein a first mode of operation is provided for vehicles having automatic transmissions and a second mode of operation is provided for vehicles having manual transmissions. The system includes means for sensing vehicle operating conditions necessary for locking vehicle doors in accordance with the two operating modes, and means for determining whether the vehicle has an automatic transmission. For vehicles having automatic transmissions, the system issues a door locking signal to lock the power door locks after an off-to-on transition of the vehicle ignition system is detected, when the automatic transmission is shifted from either the park or neutral range with the vehicle front doors closed. For vehicles having manual transmissions, the system issues a door locking signal to lock the power door locks after an off-to-on transition of the vehicle ignition system is detected, when the the speed of the vehicle exceeds a predetermined threshold speed with the vehicle front doors closed.
