    摘要: The present invention provides a general purpose driver circuit. The driver circuit is connected to a load. The driver circuit includes a controller for producing a control signal indicative of a desired output current. The driver circuit generates an output current having a magnitude responsive to the magnitude of the control signal. The driver circuit produces a system voltage feedback signal and an output voltage feedback signal and responsively performs output load condition diagnostics.

    摘要: An electronic control is provided for controlling the drive speed of a supplemental drive relative to an engine driven main drive of a vehicle. A fluid pump driven by the engine provides pressurized fluid flow. The supplemental drive is driven by the pressurized fluid. A main drive sensor senses the speed of the main drive and responsively produces a main drive speed signal. A command knob is provided for selecting a desired speed relationship between the main and supplemental drives. A knob sensor senses the position of the command knob and responsively produces a modifier signal. A modifier circuit receives the main drive speed and modifier signals and responsively produces a modified main drive speed signal. A supplemental drive sensor senses the speed of the supplemental drive and responsively produces a supplemental drive speed signal. A processor produces an error signal responsive to a difference between received modified main and supplemental drive speed signals. The processor produces a first signal responsive to a product of the error signal and a preselected constant, produces a second signal responsive to an integral of the error signal, produces a third signal responsive to a derivative of the error signal and produces a pump control signal in response to a sum of the first, second, and third signals. An actuator receives the pump control signal and responsively adjusts the pump output.

    摘要: A system for a machine having an electric drive configuration is provided. The system includes a first motor associated with a first wheel, which provides torque to drive the first wheel, a second motor associated with a second wheel, which provides torque to drive the second wheel. The system further includes a controller configured to determine a rotational speed of the first wheel, determine a rotational speed of the second wheel, determine a steering angle of the machine, compare the rotational speeds of the first and second wheels, and adjust the torque to the first wheel if the rotational speed of the first wheel is less than the rotational speed of the second wheel.
