Redundant vehicle safety lock with warning unit

摘要

Disclosed is a door locking system for a motor vehicle having a warning unit which provides a signal which can only be suppressed by manual actuation of a redundant safety locking catch such as a child lock. Sensors are used to establish whether or not the door operating system is operating safely and reliably and a warning is provided. The warning may by sounding an audible acoustic alarm or may be by means of a visual display such as illuminating a light on the dashboard of a motor vehicle. The vehicle doors may be rear doors which are linked to the rear of the vehicle body and open by pivoting towards the rear of the vehicle.
