Abstract
A vehicle, in particular a motor vehicle, a hybrid vehicle or an electric vehicle, has a first device, which has at least one element, which can have an electric voltage which is hazardous to a human being in the event of such a human being coming into touching contact therewith. The first device is electrically connected to a conductor, which has a low voltage. An accident sensor system outputs a sensor signal in the event of an accident. On output of the sensor signal, the element of the first device can automatically be switched to zero potential.

12. A hybrid or electric motor vehicle comprising:
-
a low-voltage conductor having a low voltage of less than or equal to 60 volts DC or less than or equal to 25 volts AC; a first device electrically connected to the low-voltage conductor, to generate a high voltage from the low voltage present on the low-voltage conductor such that the first device has an element, which can have an electric voltage of greater than 60 volts DC or greater than 25 volts AC which is hazardous to a human being if the human comes into touching contact with the element; and an accident sensor system, which outputs a sensor signal if an accident is detected, the sensor signal causing the element of the first device to be automatically switched to zero potential. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24, 25, 26, 27, 28, 29)

30. A method for switching to zero potential a first device of a hybrid or electric motor vehicle, wherein
the first device has an element, which can have a high electric voltage of greater than 60 volts DC or greater than 25 volts AC which is hazardous to a human being if the human being comes into touching contact with the element of the first device, the first device is electrically connected to a low-voltage conductor, which has a low voltage of less than or equal to 60 volts DC or less than or equal to 25 volts AC, the first device generates the high electric voltage from the low voltage present on the low-voltage conductor, and the method comprises: -
sensing an accident with an accident sensor system of the vehicle; outputting a sensor signal from the accident sensor system if an accident is sensed; and automatically switching the element of the first device to zero potential when the sensor signal is output.
