Patent number: 9187085Abstract: A plug-in hybrid electric vehicle operates the engine and/or traction motor in response to energy costs or prices received from an external source, such as a user or network. The vehicle can include a battery; an engine; an electric motor; a memory to store a battery charge point, and a controller to modify the battery charge point in response to arbitration criteria to control battery charging from the engine. The arbitration criteria can be based at least partially on fuel cost for the engine. The arbitration criteria can be based at least partially on electricity cost. The arbitration criteria can also include location of the vehicle. The controller may alter a deadband between charging the battery with the engine and discharging the battery to power the traction motor based on the arbitration criteria.Type: GrantFiled: April 24, 2014Date of Patent: November 17, 2015Assignee: Ford Global Technologies, LLCInventors: Venkatapathi Raju Nallapa, Kerry Eden Grand, Fazal Urrahman Syed, Ming Lang Kuang

Patent number: 6707270Abstract: System and method for enhancing the torque output of a field oriented induction motor including a controller having a plurality of predetermined control parameters operable for processing input signals to generate output signals. The plurality of predetermined control parameters are dependent upon the nature of the input signals and the operational state of the motor. A sensor system is operable for communicating feedback signals related to the output signals and the operational state of the motor from the motor to the controller.Type: GrantFiled: November 13, 2001Date of Patent: March 16, 2004Assignee: Ballard Power Systems CorporationInventors: Li Chen, Kerry Eden Grand, Richard Joseph Hampo, Vinod Reddy, Xingyi Xu, Nick Langovsky
