Abstract: A method and system for boosting a torque output of a drive train comprises an engine speed detector for detecting an engine speed of an engine having a baseline torque versus engine speed curve. A data processor determines if the detected engine speed is within a first range of engine speeds, if the detected engine speed is within the first range, the electric motor is activated to rotate substantially synchronously with the engine speed within the first range in an electric propulsion mode in accordance with a supplemental torque versus engine speed curve. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a lower engine speed point and a higher engine speed point.

Abstract: A human perception model for a speed control method obtains a steering angle, a velocity error and a distance error. The steering angle and a measure of operator aggressiveness are applied to the model. The output is defuzzified. The steering angle, the velocity error and the distance error are applied to fuzzy logic membership functions to produce an output that is applied to a velocity rule base. The measure of operator aggressiveness is input to the velocity rule base. The output from the velocity rule base is defuzzified to produce a speed signal.

Abstract: A method and system for boosting a torque output of a drive train comprises a torque sensor for detecting an engine torque of an engine having a baseline torque versus engine speed curve. A data processor determines if the detected engine torque is within a first torque range, if the detected engine torque is within the first range, the electric motor is activated to rotate substantially synchronously with a corresponding engine speed associated with the detected engine torque in accordance with a supplemental torque versus engine speed curve. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a first lower speed point and a first higher speed point.

Abstract: A vehicle steering control method including the steps of obtaining a heading error, obtaining a velocity value, obtaining a distance error, applying the heading error, inputting a measure of operator aggressiveness and defuzzifying an output from a steering rule base. The velocity value and the distance error are applied along with the heading error to fuzzy logic membership functions to produce an output that is applied to a steering rule base. A measure of the operator aggressiveness is input to the steering rule base. An output from the steering rule base is defuzzified to produce a steering signal.

Abstract: An engine speed detector detects an engine speed of an engine having a baseline torque versus engine speed curve. A torque sensor detects an engine torque of the engine. A data processor determines if the detected engine speed is within a first speed range and if the detected engine torque is within a first torque range. A motor controller activates an electric motor to rotate substantially synchronously with a corresponding engine speed associated with the detected engine torque in an electric propulsion mode in accordance with a supplemental torque versus engine speed curve if the detected engine speed is within the first speed range and if the detected engine torque is within the first torque range. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a lower speed point and a higher speed point.

Abstract: A human perception model for a speed control method including the steps of obtaining a steering angle, a velocity error and a distance error. The method further includes the steps of applying the steering angle, inputting a measure of operator aggressiveness and defuzzifying an output. The applying step includes applying the steering angle, the velocity error and the distance error to fuzzy logic membership functions to produce an output that is applied to a velocity rule base. The inputting step inputs a measure of operator aggressiveness to the velocity rule base. The defuzzifying step defuzzifies an output from the velocity rule base to produce a speed signal.
