A method of and system for automatically operating an automotive vehicle in such a manner that a desired distance may be driven with a given quantity of fuel. The system is such that after a rate of fuel consumption has been determined on the basis of the fuel available and the distance to be driven, for instance, a control monitors and adjusts the output of the engine of the vehicle appropriately. Manual operation of the vehicle in this manner is made possible by actuating perceptible warning signals whenever the vehicle is operated in a manner deviating from the desired performance.

A device for operating an automotive vehicle with a given quantity of fuel for a predetermined distance, comprising: means for generating a first signal representative of the predetermined distance; means for measuring the given quantity of fuel and for generating a second signal representative thereof; means for calculating from said first and second signals a value representative of a permissible rate of fuel consumption for operating the vehicle for said predetermined distance and for generating a third signal representative of said value; means for measuring the actual rateof fuel consumption and for generating a fourth signal representative thereof; means for comparing said third and fourth signals and for deriving a fifth signal representative of the difference between the permissible and actual rates of consumption; and means responsive to said fifth signal and cooperating with an output control member of the drive train of said automotive vehicle for adjusting the output thereof such that the actual rate of consumption substantially equals the permissible rate.
