Patent Images
1. A method of operating an internal combustion engine of a motor vehicle, the method which comprises:
- automatically starting the internal combustion engine in dependence on at least one activation condition and/or automatically deactivating the internal combustion engine in dependence on at least one deactivation condition;
measuring the at least one activation condition and/or the at least one deactivation condition while the motor vehicle is at a standstill; and
storing a presence of the activation conditions and/or deactivation conditions in a memory and evaluating the presence of the activation conditions and/or deactivation conditions in order to diagnose a control of the internal combustion engine;
starting a first time counter when the vehicle comes to a standstill, and stopping the first time counter when the vehicle starts moving; and
prohibiting a deactivation of the internal combustion engine if a value of the first time counter is higher than a predefined threshold value.
