  • Patent number: 11068002
    Abstract: A work vehicle may include a load sensor, an engine, a drive train driven by the engine and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further comprise a temperature sensor configured to sense a temperature and a vehicle control system configured to receive the sensed temperature and a vehicle load from the load sensor. The vehicle control system is configured to output a work speed vehicle alert based upon a combination of the temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor.

  • Patent number: 10520955
    Abstract: A work vehicle may include an engine, a drive train driven by the engine, and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further include a temperature sensor configured to sense a track temperature of the at least one track and a vehicle control system configured to receive the track temperature and to determine misalignment of the at least one track based at least in part upon the sensed track temperature.

  • Patent number: 9989976
    Abstract: A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the carcass. The temperature of the track may also be used to alert an operator of a track temperature issue or request that the operator reduce the speed of the vehicle.

  • Patent number: 8323144
    Abstract: A vehicle hybrid drive supplies torque to an axle. The drive includes a first engine and a transmission which couples the first engine to the axle. The drive also includes a second engine, a flywheel driven by the second engine, an electric generator driven by the flywheel, a generator controller coupled between the generator and a motor controller, and an electric motor coupled to the motor controller. A gearbox is coupled between the electric motor and the axle. The vehicle drive may also include a further flywheel driven by the first engine, with the transmission being driven by the second flywheel.
