Abstract: A hybrid vehicle powertrain including a hybrid transmission in power-flow communication with an electric traction motor, a fluid pump, and a flow controller electrically connected to the fluid pump. The fluid pump is configured to supply fluid at an adjustable fluid flow rate to the hybrid transmission and the electric traction motor in response to a command from the flow controller. The flow controller is electrically connected to the fluid pump and configured to controllably modulate the operating speed of the fluid pump to adjust the fluid flow rate. If the difference between an expected rate of speed change of the fluid pump and the actual rate of speed change exceeds a threshold, the flow controller may limit the total amount of electrical power supplied to the electric traction motor.

Abstract: A method of rationalizing a plurality of temperature sensors associated with a plurality of electrical systems of a vehicle includes: maintaining each of the respective electrical systems of the vehicle in a non-operational state for a predetermined period of time; receiving a temperature reading from each of the plurality of temperature sensors following the predetermined period of time; computing a master-reference temperature value from the plurality of received temperature readings; determining a difference between each of the respectively received temperature readings and the computed master-reference temperature value; comparing each determined difference to a threshold; and providing an indicator if one or more of the determined differences exceeds the threshold.
