Abstract
An apparatus and corresponding methods for detecting a tailgating situation involving a second motor vehicle behind an automated vehicle, and performing an automated safety routine in response to the detected tailgating situation. The tailgating situation is detected based on a simultaneous occurrence of two or more conditions involving an estimated time to collision, lateral offsets of both vehicles with respect to a center of a lane, activation of a turn signal blinker of the second motor vehicle, or flashing of a headlamp of the second motor vehicle. The safety routine includes performing a lane change to an adjacent lane. When no adjacent lanes are available for a lane change, a maximum permissible deceleration rate is decreased while increasing a time gap between the automated vehicle and a third motor vehicle directly in front of the automated vehicle by automatically adjusting an amount of at least one of acceleration or braking.
