Abstract: 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.

Abstract: A method for comprehensive integrated control of a compression-ignition internal combustion engine having integral fuel pump-injectors utilizing an electronic control unit is disclosed. The control strategy integrates various functions of engine control including fuel delivery, cooling fan control, engine speed governing and overspeed protection, engine braking, torque control, and vehicle speed diagnostics and control. Cooling fan control is integrated with vehicle speed diagnostics and control as well as fuel delivery to provide an integrated cruise control function which incorporates engine braking. The method also includes improved control over the various engine speed governors while improving idle quality by balancing the power delivered by each of the engine cylinders when at idle. The integrated torque control employs functions to reduce NOx emissions and noise utilizing adaptive fuel delivery timing and a split injection strategy.

Abstract: 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.

Abstract: A system and method for controlling an engine to limit engine output include determining engine speed, determining vehicle speed, determining a ratio based on the engine speed and the vehicle speed, comparing the ratio to a threshold, and controlling the engine to limit engine output based on the comparison. The ratio used for comparison may be selected from a plurality of ratios based on a current gear ratio which may be an actual or virtual (computed) gear ratio. The threshold may represent a low gear torque limit threshold in one embodiment. A vehicle speed sensor fault may also be considered to determine whether to limit the engine output. In one embodiment, engine output is limited by limiting engine torque.
