First Claim
Patent Images
1. A method for operating an internal combustion engine in a motor vehicle, which comprises the steps of:
- switching off automatically the internal combustion engine as soon as it is not required;
starting automatically the internal combustion engine one of as soon as it is required and as soon as a timeout has expired; and
changing the timeout in dependence on a characteristic value correlated with a capacity of a battery for supplying power to an on-board electrical system.

Abstract
A method for operating an internal combustion engine in a motor vehicle, in which the internal combustion engine is switched off automatically as soon as it is not required, and in which the internal combustion engine is started automatically as soon as it is required or as soon as a timeout has expired. In order to increase the service life of the battery, the timeout is changed in dependence on a characteristic value which is correlated with the capacity of the battery.
