Method for controlling a drive train of a hybrid vehicle
First Claim
1. A method for controlling a drive train in a hybrid vehicle comprising, requesting data which characterizes at least a portion of a route to be traveled;
- defining an operating strategy for individual components of the drive train as a function of said data;
calculating expected energy consumption as a function of said data, and/or the defined operating strategy;
determining a time period for which the calculated energy consumption can be made available;
checking whether the time period which is determined is sufficient for the operating strategy;
controlling the individual components of the drive train in accordance with the operating strategy where the time period is determined to be sufficient; and
defining an alternative operating strategy and re-checking of the resulting time period if the time period is determined not to be being sufficient.

Abstract
An operating strategy for the components of the drive train is defined as a function of data which characterizes a route to be traveled along. Depending on the operating strategy and the route data, expected energy consumption and a time period for which the energy can be made available are calculated. If the time period is detected as being sufficient, the drive train is controlled in accordance with the operating strategy. If the calculated time period is detected as not being sufficient, an alternative operating strategy is defined and the resulting time period is checked again.
