Adaptive cruise control system and method of operating the same
First Claim
1. A method for operating an autonomous or semi-autonomous host vehicle, the method comprising the steps of:
- receiving data measured from a plurality of sensors, wherein the measured data relates to one or more target vehicles in the host vehicle'"'"'s field of view;
calculating a desired speed command based on a driver-selected set-speed and the measured data;
detecting initiation of a lane change by the host vehicle from a current lane to a desired adjacent lane;
in response to initiation of the lane change, selecting an acceleration profile based on at least one set of operating conditions;
calculating a modified speed command by adjusting the desired speed command according to the selected acceleration profile; and
controlling a speed of the host vehicle based on the modified speed command.

Abstract
A system and method are provided for operating an autonomous or semi-autonomous host vehicle. The method includes receiving data measured from a plurality of sensors, wherein the measured data relates to one or more target vehicles in the host vehicle'"'"'s field of view, calculating a desired speed command based on a driver-selected set-speed and the measured data, detecting initiation of a host vehicle lane change to a desired adjacent lane, and in response to initiation of the lane change, selecting an acceleration profile based on at least one set of operating conditions, calculating a modified speed command by adjusting the desired speed command according to the selected acceleration profile; and controlling a host vehicle speed based on the modified speed command.

19. A method for operating an autonomous or semi-autonomous host vehicle, the method comprising the steps of:
-
receiving data measured from a plurality of sensors, wherein the measured data relates to one or more target vehicles in the host vehicle'"'"'s field of view; receiving a desired speed command based on a driver-selected set-speed and the measured data; detecting a lane change by the host vehicle from a current lane to an adjacent lane based on an activation of a turn signal of the host vehicle; determining a relative speed between the host vehicle and a target vehicle in the adjacent lane; selecting a positive or a negative acceleration profile based on the relative speed and a plurality of operating conditions; calculating a modified speed command by adjusting the desired speed command according to the selected acceleration profile; and controlling a response of the host vehicle in an anticipatory manner that is designed to mimic a human driver'"'"'s response based on the modified speed command.

20. A control system for a vehicle, the system comprising:
-
a plurality of vehicle sensors configured to measure data relating to one or more target vehicles in the host vehicle'"'"'s field of view; and an adaptive cruise control system configured to; receive the measured data relating to the one or more target vehicles; calculate a desired speed command based on a driver-selected set-speed and the measured data; detect initiation of a lane change by the host vehicle to a desired adjacent lane; in response to initiation of the lane change, select an acceleration profile based on at least one set of operating conditions; calculate a modified speed command by adjusting the desired speed command according to the selected acceleration profile; and control the host vehicle speed based on the modified speed command.
