Abstract
The operation of a motor vehicle is controlled by reading of a programmed memory to accelerate the vehicle along a predetermined optimum efficiency curve. The acceleration is independent of the position of the accelerator pedal, provided the pedal is neither in the idling position nor in the full throttle position. For these positions, the acceleration of the vehicle is not under the control of the programmed device.
Claims4
A method for operating an internal combustion engine to optimize an engine parameter in motor a vehicle having a multispeed transmission, a control pedal, and a fuel metering device, comprising the steps of:
- monitoring engine rotational speed;
- automatically controlling the setting of said fuel metering device after said pedal is moved from its at-rest position to provide the highest ratio of output power to fuel consumption at each engine rotational speed, said control of the setting of the fuel metering device being independent of angular variations in pedal position as long as said pedal is moved from its at-rest position;
- and
- manually controlling the desired speed and power of said engine by either shifting the speed of said transmission or selectively activating and releasing said pedal.
