Abstract: An automated lane change system for a motor vehicle includes one or more environmental sensors for generating an input signal indicative of a position of an object relative to the motor vehicle, with the object being disposed at a distance from the motor vehicle. The input signal is further indicative of a velocity of the object relative to the motor vehicle. The system further includes a steering wheel sensor generating a gripped signal, in response to a driver gripping a steering wheel. A controller generates an activation signal, in response to the controller receiving the input signal from the environmental sensor and the gripped signal from the steering wheel sensor. An actuator controls the steering wheel, a propulsion mechanism, and a braking mechanism for maneuvering the motor vehicle from a current driving lane to a target driving lane, in response to the actuator receiving the activation signal from the controller.

Abstract: The present application generally relates to a method and apparatus for generating an action policy for controlling an autonomous vehicle. In particular, the method and apparatus include a memory operative to store a map data, a sensor operative to provide a location, a yaw rate sensor operative to measure a yaw rate, a processor for receiving the yaw rate, and a processor for determining a yaw rate calibration bias in response to the yaw rate, the location, and the map data, and a vehicle controller for controlling a vehicle in response to the yaw rate calibration bias.

Abstract: Systems and methods of performing adaptive control of an automated lane change in a vehicle include positioning a target vehicle with a target speed in a target lane at a target distance behind the vehicle. The target speed is greater than a speed of the vehicle, and the vehicle will move into the target lane based on the automated lane change. The method includes determining a deceleration needed by the target vehicle over a braking distance, which is less than the target distance, to match the speed of the vehicle, and determining whether the deceleration exceeds a threshold deceleration. The automated lane change is prohibited based on the deceleration exceeding the threshold deceleration.

Abstract: A method is provided for autonomously operating a vehicle. The method includes receiving vehicle state and vehicle environment data; determining that a vehicle position is not in a position for autonomous mode based on vehicle state and vehicle environment data, wherein the position is associated with a center of one lane of a roadway; enabling a steering assistance torque for a lane-centering operation concurrently within a pre-determined period of time of engagement of the autonomous mode for a vehicular operation; blending the steering assistance torque for assisting in vehicle guidance with a torque applied by the operator for the lane-centering operation with the autonomous mode of vehicular operation engaged; and executing enablement of the autonomous vehicular operation mode with the vehicle positioned within the center of one lane of the roadway as the operator is transitioned from a hands-on to a hands-off control of the vehicle.
