Abstract
A motor vehicle, in particular electric motor vehicle or hybrid motor vehicle, which is equipped with at least one electromotively actuable motor vehicle lock, and with at least one on-board battery and with an emergency battery for application of an electromotive drive of the motor vehicle lock during normal operation and during emergency operation. According to the invention, a traction battery provided for driving the motor vehicle acts as the emergency battery during emergency operation.
Claims12
A motor vehicle comprising:
- at least one electromotively actuable motor vehicle lock including an electromotively actuable motor drive;
- at least one on-board battery for energizing the electromotively actuable motor drive of the motor vehicle lock in a normal operation;
- an emergency battery for energizing the electromotively actuable motor drive of the motor vehicle lock in an emergency operation in which there is a loss of power from the on-board battery to the motor vehicle lock,
- wherein in the emergency operation, the emergency battery is a traction battery configured for driving the motor vehicle, the traction battery being different from the on-board battery;
- and
- a switchover device, wherein the traction battery is electrically connected to the motor vehicle lock with the interposition of the switchover device, wherein the switchover device is equipped with a conversion unit configured to convert electrical energy provided by the traction battery to control the electromotively actuatable motor drive,
- wherein an input of the conversion unit is an output of the traction battery and an output of the conversion unit is provided to the electromotively actuable motor drive, and
- wherein the conversion unit is inactive during normal operation.
A method of operating a motor vehicle comprising using a traction battery of an electric motor vehicle or hybrid motor vehicle as an emergency battery for energizing an electromotive drive of a motor vehicle lock,
- wherein the motor vehicle includes a switchover device, wherein the traction battery is electrically connected to the motor vehicle lock with the interposition of the switchover device, wherein the switchover device is equipped with a conversion unit configured to convert electrical energy provided by the traction battery to control the electromotively actuatable motor drive,
- wherein an input of the conversion unit is an output of the traction battery and an output of the conversion unit is provided to the electromotively actuable motor drive, and
- wherein the conversion unit is inactive during normal operation.
