Control device for a vehicle and reset method for such a control device

A control device for a vehicle, comprising:

• a voltage supply;
• and
• multiple system components, one of the system components a processing unit which, in combination with the other system components, carries out at least one device function and selectively switches off or resets assigned individual system components depending on a function and/or depending on a state via at least one selectively generated controller reset signal, the system components being supplied by at least two different internal system voltages, at least one monitoring function monitoring the at least two internal system voltages, different corresponding voltage-related reset signals each being assigned to at least one of the monitored internal system voltages, the at least one monitoring function being configured to, as soon as the at least one assigned monitored internal system voltage is recognized to be erroneous, selectively generate the corresponding voltage-related reset signal of the at least one assigned monitored internal system voltage recognized as erroneous and selectively outputting the corresponding voltage-related reset signal to at least one system component which is supplied with the internal system voltage recognized as erroneous, the at least one voltage-related reset signal configured to incrementally switch off or reset the at least one system component supplied with the internal system voltage recognized as erroneous,
• wherein the at least one voltage-related reset signal is selected from a plurality of different voltage-related reset signals assigned to different internal system voltages and is selectively output to only the at least one system component supplied with the internal system voltage recognized as erroneous, thereby incrementally switching off or resetting only the at least one system component supplied with the erroneous voltage without resetting other system components.
