Abstract
An electronic door lock system for a vehicle includes a driver-operable child safety locking arrangement for rear passenger doors that disables interior door release handles. A separate unlocking arrangement is provided to temporarily override the child safety locking arrangement to allow opening of the rear passenger doors by their interior handles. The override, unlocking arrangement is operable by a driver and requires the simultaneous operation of the rear passenger door handle. The child safety locking arrangement is automatically reset upon release of the rear passenger door handle, without requiring any further action by the driver.
