摘要:
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.

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.

摘要:
A method for powering a system in a vehicle, the method including the steps of mechanically coupling, driving and controlling. The mechanically coupling step includes coupling a power unit with at least one primary load, the at least one primary load including a propulsion load. The driving step includes driving a cleaning fan and a cleaning shoe with at least one power source, the at least one power source being mechanically independent from the power unit. The controlling step includes controlling a speed of the at least one power source independent of a speed of the power unit.
摘要:
A vehicle arrangement includes a tow vehicle and a towed vehicle. The towed vehicle includes at least two wheels and at least one motor, with each motor being coupled with a corresponding wheel. A load sensing hitch between the tow vehicle and the towed vehicle provides an output signal representing a sensed load on the load sensing hitch. An electrical processing circuit is coupled with the load sensing hitch. The electrical processing circuit actuates at least one motor, dependent upon the output signal.
