  • Patent number: 11807268
    Abstract: Systems and methods for controlling an autonomous vehicle are described. A trajectory planner module provides a first trajectory to a trajectory control module. The trajectory control module determines parameters of the first trajectory. The trajectory control module compares the parameters to a respective threshold value. The trajectory control module obtains one or more alternative trajectories, determines parameters of each alternative trajectory, and compares the parameters of the alternative trajectory to a respective threshold value. The trajectory control module selects a trajectory for controlling the autonomous vehicle that has parameters which are within a range defined by the threshold values and controls the autonomous vehicle based on the selected trajectory. Thus, before handing back control to a driver, the trajectory control module selects from alternate trajectories for controlling the autonomous vehicle.

  • Patent number: 10919542
    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.

  • Patent number: 10919532
    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.

  • Patent number: 10852727
    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.

  • Publication number: 20200172106
    Abstract: An automotive vehicle includes an actuator, a sensor, and a controller configured to selectively control the actuator in an autonomous driving mode. The controller is configured to identify an adjacent driving lane proximate a current driving lane based on signals from the sensor.

  • Patent number: 10495012
    Abstract: An automotive vehicle includes an internal combustion engine that outputs exhaust gas from a cylinder, and an active thermal management system. The active thermal management system flows coolant around the cylinder thereby varying an exhaust temperature of the exhaust gas. An electronic engine controller controls the internal combustion engine and the active thermal management system. The engine controller generates a control signal to selectively operate the active thermal management system in a normal mode, a thermal increase mode, and a thermal decrease mode. The normal mode flows the coolant at a first coolant temperature. The thermal increase mode flows the coolant at a second coolant temperature greater than the first coolant temperature thereby increasing the exhaust temperature of the exhaust gas. The thermal decrease mode flows the coolant at a third coolant temperature less than the first coolant temperature thereby decreasing the exhaust temperature of the exhaust gas.
