A vehicle includes a pump having a swash plate tiltable about a swashplate tilt axis, wherein rotation of the swashplate changes the title angle and effects a change in volumetric displacement of the pump. A controller is operatively coupled to the swashplate to effect rotation of the swashplate, the controller including a processor and memory, and logic stored in the memory and executable by the processor, the logic configured to automatically control at least one vehicle characteristic independent of a user input command.

Controller and system for utility vehicle

A zero turn mower vehicleincludes left and right hydrostatic transmissionsdriving wheels. The transmissionseach include a swashplate type axial piston hydraulic pumphaving a swashplate. A systemand method controls each pump. A controllerreceives input signals and provides output signals to electric motorsto control each swashplate. Operator interface input devicesprovide inputs to controller. Angle sensorsprovide additional inputs to controller. Displacement amplifiersamplify displacement of each swashplate, and torque amplifiersamplify torque of electric motors

Pump control system and method

A constant pulling force winch control system includes a sensor that senses a degree of winding of a winch cable around a winch drum, and a control system configured to control a winch motor to achieve a constant pulling force on the winch cable based on the degree of winding sensed by the sensor. The sensor may be a position sensor that measures a position of the winch cable relative to a centerline of the winch drum as the degree of winding. The position sensor may sense an angular position of a tension plate relative to a tensioner shaft to measure the degree of winding. The winch motor may be a hydraulic winch motor or an electric motor, and the control system is configured to control the power applied to the hydraulic winch motor to achieve the constant pulling force based on the degree of winding sensed by the sensor.
