1. A monitoring device for a vehicle, the monitoring device comprising:
- a detector device configured to evaluate a plurality of sensor signals from at least one sensor and to identify a predetermined event on the basis of at least one of the plurality of evaluated sensor signals;
an electronic controller for a vehicle; and
an activation device configured to deactivate the electronic controller during the evaluation of the plurality of sensor signals by the detector device and to activate the electronic controller when the detector device has identified the predetermined event,wherein, when the electronic controller is activated, the electronic controller generates a control signal for initiating a countermeasure to the predetermined event, andwherein the detector device evaluates the plurality of sensor signals in a cyclically alternating manner to individually identify a malfunction of at least one selected from a group consisting of a first sensor and a second sensor, wherein the detector device evaluates the plurality of sensor signals in a cyclically alternating manner by activating the first sensor and deactivating the second sensor and, after a predetermined time, deactivating the first sensor and activating the second sensor.

Abstract
Methods and systems for monitoring a vehicle. In a parked state of the vehicle, the control unit of the vehicle is deactivated, and the signals of some of the sensors of the vehicle are detected and evaluated by way of a separate detecting unit. If, based on the sensor signals evaluated in this way, a defined event is detected, the previously deactivated control unit can be activated. Thus, the operating time of the control unit is minimized over the total life span of the vehicle.

15. A method for monitoring a vehicle, the method comprising the steps of:
-
deactivating an electronic controller of the vehicle; detecting a plurality of sensor signals in a cyclically alternating manner to individually identify a malfunction of at least one selected from a group consisting of a first sensor and a second sensor, wherein a detector device evaluates the plurality of sensor signals in a cyclically alternating manner by activating the first sensor and deactivating the second sensor and, after a predetermined period of time, deactivating the first sensor and activating the second sensor; identifying a predetermined event on the basis of at least one of the plurality of detected sensor signals; activating the control device of the vehicle when the predetermined event has been identified; and generating a control signal for initiating a countermeasure to the predetermined event.
