A METHOD TO LIMIT THE FUEL CONSUMPTION IN A VEHICLE

摘要

A method to improve a fuel efficiency of an engine in a vehicle is disclosed. A speed of the vehicle is determined and is compared with a threshold speed. A time lag of a press of an accelerator pedal 14 or a brake pedal 16 for at least two iterations is determined, if the vehicle speed is less than the threshold speed. The time lag value is converted into frequency value. A limitation function is activated when the converted frequency value value is more than a threshold frequency value value. A vehicle weight is calculated, if said limitation function is active and is compared with a predefined vehicle weight. A rate of rise of a torque or an injection quantity or both is limited if the vehicle weight is less than the predefined vehicle weight. Figure 1
