Patent number: 11068002Abstract: 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.Type: GrantFiled: October 13, 2019Date of Patent: July 20, 2021Assignee: DEERE & COMPANYInventors: Daniel Garvin, Ronica L. McKinley, Narasimhan Rangan, Janet R. Willett, Bruce L. Upchurch, Jeremy P. L'Heureux

Patent number: 9989976Abstract: 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.Type: GrantFiled: September 14, 2016Date of Patent: June 5, 2018Inventors: Daniel Garvin, Ronica L. McKinley, Narasimhan Rangan, Janet R. Willett, Bruce L. Upchurch, Jeremy P. Lheureux

Patent number: 8323144Abstract: 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.Type: GrantFiled: May 10, 2011Date of Patent: December 4, 2012Assignee: Deere & CompanyInventors: Shi Bin, Andrew K. Rekow, Janet R. Willett
