Abstract

A motor vehicle has a plurality of doors, each secured by a lock, peripheral control units, each connected to one of said locks, for sending a command signal to an actuator of the lock, a central control unit for sending command signals to the actuators of the locks, and an accident detector. If the accident detector has detected an accident, at least one of the actuators is switchable from a central operating mode in which it executes command signals of the central control unit and its associated peripheral control unit into a peripheral operating mode in which it executes only command signals from its peripheral control unit.

Description

technical field [0001] The technical field relates to a motor vehicle having a plurality of doors secured by a lock and a central locking system capable of switching the locks between locked and unlocked states. Background technique [0002] A motor vehicle is known, for example, from DE 10 2009 010 509 A1. Such conventional central locking systems for motor vehicles include a central control unit adapted to receive remote control signals and address peripheral control units of the doors in response to the remote control signals, which then switch the door locks between locked and unlocked states. In the locked state, the door lock does not respond to the operation of an external operating device mounted on the outside of the door; from the unlocked state, the door lock can be brought into the released state by the operation of its associated external operating device. In the released state, the door is freely transferable between closed and open positions. [0003] In eac...
