Abstract

A method for controlling a hybrid motor vehicle which has an electromotive internal combustion engine, which is operated by an electric accumulator and is operatively connected to a generator for the charging of the accumulator, and a control unit for controlling the drive unit, in particular the internal combustion engine as a function of the charge state of the accumulator. So that the internal combustion engine is operated advantageously, in addition to a control process as a function of the charge state of the accumulator, in order to protect the control unit and/or for the effective operation thereof, the internal combustion engine is controlled, at least as a function of a retrieved continuous power rating of the accumulator, a temperature of the accumulator, of vibrations occurring in the motor vehicle and/or of a downtime of the internal combustion engine.
