A vehicle includes a multi-core processor having first, second, and cores and having first and second analog-to-digital converters (ADC) associated with the first and second cores, respectively. The first and second ADC are configured to convert analog phase currents to first and second digital phase current values, respectively. The multi-core processor is configured to generate first and second rotor-angle data from digital signals representing a position of the electric machine. The processor is programmed to, via the first core, estimate a first output torque of the electric machine based on the first rotor-angle data and the first digital phase current values, via the second core, estimate a second output torque based on the second rotor-angle data and the second digital phase current values, and, via the third core, command de-activation of the electric machine in response to a difference between the first and second output torques exceeding a threshold.

Systems and methods to determine and validate torque of an electric machine

A vehicle includes a controller configured to deactivate an inverter driving the rotor. The deactivation being responsive to respective speeds for a rotor derived from respective samples from each of a monitoring core and a current control core over a same temporal window being different by a threshold amount. The cores each generate a different number of the samples due to having different chronometric periods and the temporal window being greater than the chronometric periods.

Rotor position measurement and control

An example electric vehicle charging method includes charging a battery of a vehicle using an external power source, and adjusting the charging based on a predicted amount of charging generated when driving the vehicle from the external power source to a destination. The external power source is at a higher elevation than some point along the route to the at least one destination.

Electric vehicle charger and charging method

A method for controlling torque delivery in a vehicle powertrain using an enhanced limited operating strategy. The strategy is implemented when a powertrain controller fails to respond properly to a driver command for traction wheel torque whereby a modified wheel torque at vehicle traction wheels under driver control is made available.

Method for providing improved driveability for a vehicle

Systems, apparatus, and methods are presented to transfer energy between an energy storage device (ESD) at an electrified vehicle (EV) and an AC or DC external load such as an electric grid, appliance or power tool. A portable EVETA can engage an EV charge inlet couple an EV, and can provide an AC outlet, a grid interface and a DC connector for coupling external loads. An EVETA can be used at a remote construction site or campsite to power high current equipment, obviating the need to transport an electric generator. An EVETA can be configured for data and control communication with the EV to coordinate energy transfer. An EVETA can receive a predetermined ESD state of charge limit so that the transfer process can be terminated to preserve sufficient charge for EV return to a desired destination. A human machine interface enables user input reception and information display.

Portable EV energy transfer apparatus and method

A battery electric vehicle life support system for a battery electric vehicle. The system may include at least one controller adapted to receive charging station location data; a vehicle battery interfacing with the at least one controller, the at least one controller adapted to receive state of charge data from the vehicle battery; and the at least one controller adapted to determine a probability that the vehicle will reach at least one battery charging station based on the state of charge data and the charging station location data. A battery electric vehicle life support method is also disclosed.

BEV life support system and method

A system and method for controlling an electric-vehicle is provided. The system and method calculates a likelihood of arriving at a destination based on vehicle data and a current route. The likelihood is compared to least a first threshold and a second threshold. A first action is implemented when the likelihood is less than the first threshold and greater than the second threshold. A second action being different from the first action is implemented when the likelihood is less than the second threshold.

User interface system and method

A portable charging device can provide controllable fast DC charging of an electric vehicle (EV) high voltage battery by a separate EV high voltage battery. The charging device can be configured to comply with universal standards for EV charging so as to be compatible with various automobile models of various manufacturers. The device can be configured to establish a communication link with a donor and recipient vehicle and conduct a voltage matching process between the batteries of the two vehicles prior to transferring power to the recipient vehicle battery. To prevent energy theft, control of a charging process can be shared among the charging device and the donor and receiver vehicles. A charger device can be configured to enable a charging process only when no faults are detected. A charger device can allow a motorist to quickly recharge a depleted high voltage battery at a convenient time and location.

Method and apparatus for high-voltage DC charging of battery-electric and plug-in hybrid electric vehicles

A system and method for obtaining an emergency recharge in an electric vehicle is provided. The system may leverage a network of electric vehicle owners and drivers to facilitate a peer-to-peer emergency recharge of an electric vehicle unable to reach a charging station before its energy storage device is depleted. A list of potential rescuers willing to provide portable charging assistance may be generated. Out-of-range rescue vehicles may be filtered from the list. The list of potential rescuers may then be sorted based on drive time to an intercept location. Potential rescuers from the list may be sequentially contacted according to the sort order until a request for portable charging assistance is accepted. Drivers of both the soon to be stranded vehicle and the rescue vehicle may receive route guidance from navigation systems to a mutually agreeable intercept location where the peer-to-peer emergency recharge can take place.

Electric vehicle emergency recharge assistance

A method and system for estimating CO2 produced by an internal combustion engine disposed in a vehicle and transmitting the CO2 produced to a display device within the vehicle are disclosed. Estimated CO2 produced is based on amount of fuel consumed and fuel composition, e.g., alcohol content in a gasoline-alcohol blend. The amount of fuel consumed is computed based on fuel pulse width commanded to fuel injectors disposed in the engine, the pressure drop across the fuel injectors, and fuel injector nozzle cross-section. Instantaneous CO2 produced and/or average CO2 produced can be computed and displayed. Instantaneous CO2 produced is averaged over a short interval with the display updated regularly. Average CO2 produced is averaged over a typically longer interval, being reset, in one embodiment, by an operator of the vehicle depressing a reset button.

CO2 information display and method

A method of controlling a hybrid propulsion system of a vehicle, the hybrid propulsion system including an internal combustion engine and an alternate powertrain torque source capable of propelling the vehicle while the engine is turned off, the method comprising of detecting congestion by receiving and analyzing data that is external to the vehicle, and controlling a transition of the hybrid propulsion system between a first propulsion mode and a second propulsion mode based on said detecting of congestion.

Congestion-based control of vehicle hybrid propulsion system

A notification system for a vehicle includes at least a first and a second power source. The notification system also includes a controller that is operable with the first and second power sources and is configured to determine operating modes of the first and second power sources. The controller is also adapted to generate signals that correspond to the operating modes and operating limitations of the vehicle to effect an audible indication in the form of a voice message that may include a vehicle system limitation message for a vehicle operator.

Voice notification system for a vehicle

A vehicle engine is controlled based on a distance between the vehicle and an object other than the vehicle. In at least one embodiment, a system for controlling an engine in a vehicle is provided. The system includes an environment sensor arrangement configured to sense a distance between the vehicle and an object other than the vehicle and an operating sensor arrangement configured to sense an operating state of the vehicle. The system also includes a control module configured to determine whether to start or stop the engine based on the distance and the operating state.
