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: 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.
