1. A method for monitoring a motor vehicle, comprising:
- monitoring, by a speed sensor, a speed of the motor vehicle;
determining, by a control unit and based on the speed of the motor vehicle indicated by output of the speed sensor, whether the speed of the motor vehicle is below a predefined speed threshold value;
determining, by the control unit and based on an identified state of at least one component of the vehicle, at least one vehicle operating condition indicating an imminent acceleration of the vehicle; and
triggering, by the control unit, a fault response responsive to satisfaction of both conditions that (i) the speed of the vehicle is below the predefined speed threshold value, and (ii) it is determined by the control unit that no component of the vehicle has been operated by the driver to effect the detected imminent acceleration of the vehicle;
wherein the fault response is at least one of a suppression of a fuel injection, a deactivation of an engine controller of an engine, and an intervention in a power transmission.

Abstract
A method for monitoring a motor vehicle includes: monitoring whether a speed of the motor vehicle indicates a stopping condition of the motor vehicle; detecting whether at least one vehicle operating condition indicating an imminent unintentional acceleration of the vehicle exists; and triggering a fault response if (i) the vehicle is in the stopping condition and (ii) the at least one vehicle operating condition indicating an imminent unintentional acceleration of the vehicle exists.
