Patent number: 11142088Abstract: A vehicle control system controls operation of motors of a vehicle and determines whether there is sufficient stored electric energy to power the vehicle through an unpowered segment of a route. The controller changes operation of the vehicle to ensure that the vehicle can travel completely through the unpowered segment by switching which energy storage device provides energy, changing vehicle speed, changing motor torque, changing which route is traveled on, selecting fewer motors to power the vehicle, requesting rendezvous with a recharging vehicle, running the energy storage devices in a degraded mode, initiating a motor to generate power to aid in propulsion and/or recharge the energy storage devices, selecting a different route, controlling the vehicle to draft or mechanically couple to another vehicle, and/or controlling the vehicle to gain momentum or to generate an overcharge.Type: GrantFiled: February 27, 2019Date of Patent: October 12, 2021Assignee: TRANSPORTATION IP HOLDINGS, LLCInventors: Sharath Srinivas Deshpande, Vishram Vinayak Nandedkar, Ajith Kuttannair Kumar, Wolfgang Daum, Glenn Robert Shaffer

Patent number: 10618531Abstract: A method and system determine, during movement of a vehicle system along a route, a tractive load demanded by the vehicle system to propel the vehicle system along the route. The vehicle system includes a propulsion-generating vehicle having plural individually controllable traction motors. A first selected set of the traction motors for deactivation is identified during the movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system. The traction motors in the first selected set are deactivated while at least one of the traction motors in a first remaining set of the traction motors continues to generate tractive effort to propel the vehicle system. The traction motors that are selected for deactivation may all be on the same vehicle in the vehicle system, or may be on different vehicles of the same vehicle system.Type: GrantFiled: October 17, 2018Date of Patent: April 14, 2020Assignee: GE GLOBAL SOURCING LLCInventors: Sharath Srinivas Deshpande, Vishram Vinayak Nandedkar, Ajith Kuttannair Kumar

Patent number: 8862291Abstract: A system for verifying a route segment that a vehicle is traveling along includes a magnetic sensor and a control unit. The magnetic sensor generates an output signal based on an orientation of the sensor relative to an external magnetic field. The control unit receives an operator-designated route segment. The operator-designated route segment represents a selected route segment of the route segments that is identified by the operator as being the route segment on which the vehicle is traveling. The control unit identifies a directional heading of the vehicle based on the output signal from the magnetic sensor and determines an actual route segment of the routes segments in the network that the vehicle is actually traveling along based on the directional heading of the vehicle. The control unit verifies that the actual route segment on which the vehicle is actually traveling is the selected route segment.Type: GrantFiled: March 27, 2012Date of Patent: October 14, 2014Assignee: General Electric CompanyInventors: Ankit Sharma, Ajith Kuttannair Kumar, Vishram Vinayak Nandedkar
