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.

Abstract: A method of operating a motor vehicle includes a vehicle controller receiving, from a first feedback sensor of an HV component, a first feedback signal indicative of an electrical characteristic of the HV component, and then detecting an HV system fault if the first feedback signal is less than a predefined electrical threshold. Upon detecting the system fault, the controller commands the HV component to operate at a commanded set-point; after sending the command, the controller receives, from a second feedback sensor of the HV component, a second feedback signal indicative of an operating characteristic of the HV component. An HV pathway failure is detected if the second feedback signal is not equal to or within a predefined operating range of the commanded set-point. Upon detecting the pathway failure in an HV electrical pathway of the HV component, the vehicle controller transmits a command signal to take a remedial action.

Abstract: A vehicle includes drive wheels, an energy source having an available energy, a torque-generating device powered by the energy source to provide an input torque, a transmission configured to receive the input torque and deliver an output torque to the set of drive wheels, and a controller. The controller, as part of a programmed method, predicts consumption of the available energy along a predetermined travel route using onboard data, offboard data, and a first logic block, and also corrects the predicted energy consumption using the onboard data, offboard data, and an error correction loop between a second logic block and the first logic block. The controller also executes a control action with respect to the vehicle using the corrected energy consumption, including changing a logic state of the vehicle.

Abstract: A pedal electric cycle (e-bike) includes a road wheel connected to a frame, a crankset imparting a rider torque to the road wheel when a rider manually rotates the crankset, a battery pack having a state of charge (SOC), an electric traction motor, and a controller. In response to motor control signals, the motor imparts an electric-assist (e-assist) torque to the road wheel as a torque multiplier. The controller uses an energy cost function, and in response to input signals including a travel route and a desired e-assist objective, commands the e-assist torque via the motor control signals to augment the rider torque while satisfying the e-assist objective. The level is determined via the energy cost function, with the input signals including the SOC, inclination data describing a grade of each road segment of the route, and an electric model providing the torque multiplier.

Abstract: A method and system used to identify an optimal hybrid vehicle operating mode based on a variety of potential factors, and then recommend the optimal operating mode to the driver so that they can make an informed decision regarding their operating mode selection. In one embodiment, the method uses geographic-, vehicle- and/or environmental-related factors to establish one or more operating zones, monitors the location of the hybrid vehicle and determines when it is within one of the operating zones, and then determines an operating mode that is optimal for that particular operating zone.

Abstract: A method for adapting a usage level of a battery pack includes measuring cell sense data for each respective battery cell using a cell sense circuit, the cell sense data including a cell voltage, current, and temperature. The method includes processing the cell sense data, for each respective battery cell, through multiple battery state functions of a controller to generate numeric cell degradation values (CDVs). The battery state functions are calibrated relationships of the cell sense data to predetermined battery fault conditions. Thereafter, the method includes automatically adapting the usage level of the battery pack during operation of the battery pack, via the controller, based on the numeric CDVs. An electric powertrain system includes the battery pack, cell sense circuit, a rotary electric machine, and a controller configured to execute the above method.

Abstract: Methods and systems are provided for monitoring a state of health (SOH) of a battery system of an electric vehicle (EV). A projected SOH value of the battery system at one of a future vehicle age and a future total EV mileage is generated. The projected SOH value is based in part on a current SOH value and historical SOH values associated with use of the battery system to supply power to at least one of an offboard vehicle load and an onboard accessory load. A determination is made regarding whether the projected SOH value is less than a SOH threshold at the one of the future vehicle age and the future total EV mileage. A customer SOH alert regarding use of the battery system to supply power to the at least one of the offboard vehicle load and the onboard accessory load is generated based on the determination.
