Abstract

A control system has at least one electronic control unit for controlling an internal combustion engine in a hybrid vehicle, which records at least the vehicle speed and the driver's desired driving performance and the driving performance specified by a safety control system or a driver assistance system. The control unit is designed such that, below a pre-defined vehicle speed threshold and/or in the event of recognition of an urban area, while in a purely electric driving mode, it only engages the internal combustion engine when the current desired driving performance exceeds a pre-defined upper threshold, preferably once the maximum tractive force at the wheel for purely electric driving is at least reached.
