US 2023/0406301 A1 · VEHICLE SYSTEMS AND RELATED METHODS TO AUTONOMOUSLY INCREASE CAMERA RANGE

Abstract

Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves determining a current value for a range of view associated with a sensing device onboard the vehicle, determining a target value for the range of view based at least in part on a speed of the vehicle, and in response to determining the current value is less than the target value, determining a dropback adjustment distance based at least in part on a difference between target value for the range of view and an estimated distance to a closest in path (CIP) vehicle ahead of the vehicle within a current lane of travel, determining a longitudinal trajectory for the vehicle based at least in part on the dropback adjustment distance, and autonomously operating one or more actuators onboard the vehicle in accordance with the longitudinal trajectory.

Dependent claims

A method of controlling a vehicle in an autonomous operating mode, the method comprising:

determining, by a controller associated with the vehicle, a current value for a range of view associated with a sensing device onboard the vehicle;
determining, by the controller, a target value for the range of view associated with the sensing device based at least in part on a speed of the vehicle;
and
in response to determining the current value is less than the target value:
determining, by the controller, a dropback adjustment distance based at least in part on a difference between the target value for the range of view and an estimated distance to a closest in path (CIP) vehicle ahead of the vehicle within a current lane of travel;
determining, by the controller, a longitudinal trajectory for the vehicle based at least in part on the dropback adjustment distance to increase the estimated distance to the CIP vehicle;
and
autonomously operating, by the controller, one or more actuators onboard the vehicle in accordance with the longitudinal trajectory.

A non-transitory computer-readable medium comprising executable instructions that, when executed by a processor, cause the processor to:

determine a current value for a range of view associated with a sensing device onboard a vehicle;
determine a target value for the range of view associated with the sensing device based at least in part on a speed of the vehicle;
and
in response to determining the current value is less than the target value:
determine a dropback adjustment distance based at least in part on a difference between the target value for the range of view and an estimated distance to a closest in path (CIP) vehicle ahead of the vehicle within a current lane of travel;
determine a longitudinal trajectory for the vehicle based at least in part on the dropback adjustment distance to increase the estimated distance to the CIP vehicle;
and
autonomously operate one or more actuators onboard the vehicle in accordance with the longitudinal trajectory.
