TAILGATING SITUATION HANDLING BY AN AUTOMATED DRIVING VEHICLE
First Claim
1. A computer implemented method, comprising:
- detecting, by a processor of a computer in a first motor vehicle, while the first motor vehicle is in an automated driving mode, a tailgating situation involving a second motor vehicle behind the first motor vehicle; and
responsive to the detected tailgating situation, performing an automated safety routine including;
as an initial course of action, performing a lane change to an adjacent lane when the adjacent lane is available; and
when no adjacent lanes are available for a lane change, decreasing a maximum permissible deceleration rate while increasing a time gap between the first motor vehicle and a third motor vehicle directly in front of the first motor vehicle by automatically adjusting an amount of at least one of acceleration or braking.

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.

14. An automated driving apparatus, comprising:
a control circuit in a first motor vehicle, the control circuit operable to; receive data from a plurality of sensors positioned along a perimeter of the first motor vehicle, the sensors including radar sensors, Light Detection and Ranging (LIDAR) sensors, and cameras; detect, while the first motor vehicle is in an automated driving mode, a tailgating situation involving a second motor vehicle behind the first motor vehicle; and responsive to the detected tailgating situation, perform an automated safety routine including; as an initial course of action, initiating a lane change to an adjacent lane when the adjacent lane is available; and when no adjacent lanes are available for a lane change, decreasing a maximum permissible deceleration rate while increasing a time gap between the first motor vehicle and a third motor vehicle directly in front of the first motor vehicle by automatically adjusting an amount of at least one of acceleration or braking. - View Dependent Claims (15, 16, 17, 18, 19, 20)
