Abstract

A drive system for a motor vehicle comprising a power train made up of an IC engine with an associated transmission and a brake system, operating elements for control of the power train and control devices for modifying the function of the power train to take into account operational data and characteristic curves of the operating elements, such operating elements being designed to generate output control signals and transmit them to the control devices. The control devices comprise an electronic engine electronic control means, a transmission electronic control means for self-contained automatic control of the engine and the transmission respectively, and a supervising computer which is adapted to coordinate the functions of the engine and transmission electronic control means for optimizing operation of the power train by coordinating the functions of the electronic systems for the engine and the transmission. At least a part of the signals from the operating elements are supplied directly to the super vising computer.
