    摘要: An engine with transport delay represented by a delay period is controlled with a controller in the feed-forward path and a compensator in a negative inner feedback loop around the controller. The controller generates a control signal so as to control the engine as if the engine was without the delay. A compensation signal is generated as the sum of the control signal only over the delay period. The control signal is based on an error signal generated as the difference between a desired input and the sum of a controlled engine output and the compensation signal.

    摘要: A method for comprehensive integrated control of compression-ignition internal combustion engine, wherein the control strategy integrates various functions of engine control with cooling fan control, and wherein the cooling fan control automatically ramps down cooling speed for multi-speed cooling fans whenever monitored engine conditions effecting cooling fan operation dictate transition of the multi-speed cooling fan from a high speed to an off condition.

    摘要: A system and method for controlling the fuel pressure in a common rail fuel injection system which electronically controls a variable output high pressure pump based upon engine speed, torque and actual common rail pressure inputs, as well as the present system voltage, thereby providing simple yet stable control of the fuel pressure in the accumulator of the common rail system which is relatively insensitive to supply voltage fluctuations from the power source providing the electrical power to the solenoid-controlled valve which controls the high pressure pump.

    摘要: An efficiency gauge may be used for controlling an automotive vehicle. At least one vehicle parameter is sampled during vehicle operation and at least one measure of driving efficiency is determined from the sampled vehicle parameters. Efficiency measurement may include determining an estimate of kinetic energy lost. One such estimate is the sampled braking velocity cost found based on the difference of the squares of the last two vehicle velocities if the vehicle has decelerated and braking has occurred.
