    Abstract: A system and method for determining when to display frontal curb view images to a driver of a vehicle, and what types of images to display. A variety of factors—such as vehicle speed, GPS/location data, the existence of a curb in forward-view images, and vehicle driving history—are evaluated as potential triggers for the curb view display, which is intended for situations where the driver is pulling the vehicle into a parking spot which is bounded in front by a curb or other structure. When forward curb-view display is triggered, a second evaluation is performed to determine what image or images to display which will provide the best view of the vehicle's position relative to the curb. The selected images are digitally synthesized or enhanced, and displayed on a console-mounted or in-dash display device.

    Abstract: A driver alert system includes a computer processor disposed in a vehicle. The computer processor is configured to receive driver attention data over a vehicle network during a driving event. The computer processor executes logic to process the driver attention data and evaluate the driver attention data for a triggering event. The system also includes a steering wheel unit disposed in the vehicle and lights that are integrated on a front windshield-facing surface of a steering wheel of the steering wheel unit. The lights are positioned at an angle to reflect light off of a front windshield of the vehicle. The system also includes a controller disposed in the steering wheel unit. The controller is communicatively coupled to the lights and the vehicle network. The controller receives a request from the computer processor to activate the lights when the triggering event has occurred.

    Abstract: A propulsion system for a device includes an electric motor configured to generate torque to propel the device. The electric motor includes a stator and a rotor with one or more permanent magnets. A controller is in communication with the electric motor and has recorded instructions for a method for minimizing demagnetization in the one or more permanent magnets. The controller is adapted to select a starting point and an intermediate point on a current trajectory in a stator current graph. The controller is adapted to obtain a final point on the stator current trajectory based on a comparison of the intermediate point and a predetermined voltage limit. A demagnetized torque capability is generated based on the final point on the current trajectory.

    Abstract: A distributed battery power system having a battery pack and a battery controller. The battery pack has: a plurality of cells configured to generate a plurality of cell voltages; a voltage current temperature module electrically connected to the plurality of cells; and a plurality of isolation switch sets electrically connected between the plurality of cells. The battery controller is in communication with the voltage current temperature module, and operable to: send a status request to the voltage current temperature module; receive the plurality of cell voltages from the voltage current temperature module in response to the status request; determine if the plurality of cells includes one or more problem cells in response to the plurality of cell voltages; and perform an action in response to determining that the one or more problem cells are present to prevent damage to the one or more problem cells.

    Abstract: A method of displaying a captured image on a display device of a driven vehicle. A scene exterior of the driven vehicle is captured by an at least one vision-based imaging and at least one sensing device. A time-to-collision is determined for each object detected. A comprehensive time-to-collision is determined for each object as a function of each of the determined time-to-collisions for each object. An image of the captured scene is generated by a processor. The image is dynamically expanded to include sensed objects in the image. Sensed objects are highlighted in the dynamically expanded image. The highlighted objects identifies objects proximate to the driven vehicle that are potential collisions to the driven vehicle. The dynamically expanded image with highlighted objects and associated collective time-to-collisions are displayed for each highlighted object in the display device that is determined as a potential collision.

    Abstract: A method of displaying a captured image on a display device of a driven vehicle. A scene exterior of the driven vehicle is captured by an at least one vision-based imaging device mounted on the driven vehicle. Objects in a vicinity of the driven vehicle are sensed. An image of the captured scene is generated by a processor. The image is dynamically expanded to include sensed objects in the image. The sensed objects are highlighted in the dynamically expanded image. The highlighted objects identify vehicles proximate to the driven vehicle that are potential collisions to the driven vehicle. The dynamically expanded image is displayed with highlighted objects in the display device.
