Abstract

A drive system for an automobile includes a combustion engine, a friction clutch, a multistep gearbox, a controller for controlling the combustion engine based on load lever position, clutch position, gear input shaft rotation speed, gear output shaft rotation speed, engaged gear stage, vehicle speed and/or vehicle acceleration, with a sensor connected with the controller determining a position of the friction clutch. A method for controlling this combustion engine includes the steps of receiving or generating with the controller information about a gear stage change, a clutch position change, a predetermined minimum vehicle speed and-or a predetermined maximum vehicle acceleration, and adjusting the rotation speed of the combustion engine in response to the received or generated information. This approach provides a particularly smooth and comfortable gear stage change.
