Abstract: A system for mode selective control of an electric vehicle during a race. The system may include a demand controller configured for determining a demand made by a driver during the race to control a propulsion system to propel the vehicle, a battery controller configured for determining a supply of electrical power available from a rechargeable energy storage system (RESS) to meet the demand, a temperature controller configured for determining temperature thresholds for the RESS and the propulsion system, and a supply controller configured for controlling use of the supply according to an endurance mode and a qualify mode.

Abstract: The present application generally relates to a method and apparatus for driving automation control of a motor vehicle. In particular, the system is operative to determine a vehicle maneuver, such as a lane change, and provide a first kinesthetic cue to a supervisory driver or vehicle occupant indicating the start of a vehicle maneuver. The system and method are then operative to complete the vehicle maneuver and provide a second kinesthetic cue indicating the completion of the vehicle maneuver.

Abstract: The present application generally relates to a method and apparatus for lane changes performed by an assisted driving control system in a motor vehicle. In particular, the system is operative to determine a requirement for a lane change, to determine a first headway between a host vehicle and a lead vehicle and a second headway between the host vehicle and an adjacent vehicle occupying the desired lane. The velocity of the host vehicle is adjusted in response to the first headway and the second headway and the lane change is initiated in response to the second headway exceeding an adequate distance.

Abstract: An automotive vehicle includes at least one actuator configured to control vehicle steering, shifting, acceleration, or braking, at least one sensor configured to provide signals indicative of road geometry in the vicinity of the vehicle, and a controller in communication with the sensor and the actuator. The controller is configured to selectively control the actuator in an autonomous driving mode based on signals from the sensor. The controller is configured to automatically determine a first time parameter based on a distance to a merge location between a current driving lane of the vehicle and a target lane adjacent the current driving lane in response to signals from the sensor, to automatically determine a second time parameter based on a calculated merge completion time, and to automatically discontinue autonomous control of the actuator based on a difference between the first time parameter and the second time parameter.

Abstract: Methods and systems are provided for implementing a lane control feature for vehicles having a passenger side, a driver side, one or more wheels on the passenger side, and one or more wheels on the driver side. A sensor is configured to obtain information pertaining to operation of a vehicle with respect to a lane of a roadway. The processor is coupled to the sensor, and is configured to at least facilitate determining, using the information, whether the lane control feature is activated, and providing differential torque between one or more driver side wheels and one or more passenger side wheels when the lane control feature is activated.
