Abstract: A method for controlling a diesel engine, is provided where when a vehicle is traveling on a downgrade, an enable vehicle speed is set according to a calculated aiming error, and a vehicle speed limit is modified based on an accelerator pedal position and by an offset value that is set according to an enable error calculated based on the present vehicle speed limit, the present vehicle speed, and the enable vehicle speed.

Abstract: A device for preventing unbalance between respective engine cylinders of a motor vehicle adapted to adjustingly control the fuel amount supplied to each cylinder of the engine, and the injection time, according to engine revolution changes to thereby reduce engine noise caused by deviation of engine revolutions. The device includes: a unit for detecting engine speed and fuel amount relative to each cylinder when fuel is supplied to each cylinder of the engine; a unit for respectively adjusting injection pulse width responsive to the engine speed and fuel amount detected by the detecting unit; and a unit for establishing a driving time of injection to each cylinder for the engine speed to be close to a reference speed for the injection pulse widths of the respective cylinders.

Abstract: In a method for controlling a diesel engine, it is first determined if a vehicle is travelling on a downgrade, then a predetermined fuel supply cut-off signal is output if the vehicle is travelling on a downgrade. Next, an error between a vehicle speed limit and a present vehicle speed is calculated, and an aiming speed is set as a first predetermined value to determine an aiming error, after which it is determined if the aiming error is greater than 0 and an enable vehicle speed is set as a second predetermined value when the aiming error is greater than 0. the enable vehicle speed is set to 0 when the aiming error is less than 0. Next, the error between the vehicle speed limit and the present vehicle speed is subtracted from the enable vehicle speed to get an enable error, then it is determined if the enable error is greater than 0. When the enable error is greater than 0, an offset vehicle speed Off is set as a third predetermined value.

Abstract: An automatic cruise control method for vehicles is initiated by firstly selecting an automatic cruise mode.
