The present invention relates to a motor vehicle that is equipped with an electrical door closing mechanism, a radio-based signal receiver and a control unit, wherein the door closing mechanism can be actuated after receiving and verifying an access authorization code by electrical signals that are generated by a control unit. The motor vehicle possesses an electrical charging apparatus accessible from the outside so that a signal generator that is provided to generate the access code can be charged from the electrical system of the motor vehicle in the event of an insufficient charge. Furthermore, the invention describes a method for charging a signal generator that can be executed using the device according to the invention.

Motor vehicle

A method for a high-voltage energy system of a vehicle wherein a pre-accident error state is determined which shows the current existing error of the high-voltage energy system prior to the time of an accident. Then an accident event is determined. A post-accident error state is determined which shows the current existing error of the high-voltage energy system according to the time of the accident. The high-voltage energy system is deactivated in accordance with the accident, the pre-accident error state, and the post-accident error state.

Method and device for a high-voltage energy system of a vehicle

An airbag control device, wherein the airbag control device generates at least one actuation signal for an actuation time as a function of at least one sensor signal, wherein the airbag control device can maintain the at least one actuation signal for a holding time, wherein the airbag control device has at least one non-volatile memory in which the generation of the at least one actuation signal can be stored, wherein the airbag control device, when the at least one actuation signal is generated, stores a status signal in the at least one non-volatile memory or in a further non-volatile memory, wherein the status signal is deleted again if the at least one actuation signal was generated for longer than a storage time. Also disclosed is a voltage network in a motor vehicle and to a method for actuating a voltage network.
