Abstract
A method includes the identification of a current trajectory of an automated vehicle based on a movement of the automated vehicle through a marshaling environment, the calculation of a distance-based differential between the current trajectory of the automated vehicle and an expected trajectory of the automated vehicle, the determination of whether the distance-based differential exceeds a variation threshold, and the recalibration of one or more sensors of an infrastructure system in response to the distance-based differential exceeding the variation threshold.
Claims20
A method comprising:
- identifying a current trajectory of an automated vehicle based on a movement of the automated vehicle through a marshaling environment, wherein the current trajectory is based on a current location of the automated vehicle and a current speed of the automated vehicle;
- calculating a distance-based differential between the current trajectory of the automated vehicle and an expected trajectory of the automated vehicle, wherein the expected vehicle trajectory is based on a target path of the automated vehicle and a target speed of the automated vehicle;
- determining whether the distance-based differential exceeds a variation threshold;
- and
- recalibrating one or more sensors of an infrastructure system in response to the distance-based differential exceeding the variation threshold, wherein the recalibration of the one or more sensors is based on a vehicle perception analysis.
A system comprising:
- an infrastructure system configured to:
- identify a current trajectory of an automated vehicle based on a movement of the automated vehicle through a marshaling environment, wherein the current trajectory is based on a current location of the automated vehicle and a current speed of the automated vehicle,
- calculate a distance-based differential between the current trajectory of the automated vehicle and an expected trajectory of the automated vehicle, wherein the expected vehicle trajectory is based on a target path and a target vehicle speed,
- determine whether the distance-based differential exceeds a variation threshold, and
- recalibrate one or more sensors of the infrastructure system in response to the distance-based differential exceeding the variation threshold, wherein the recalibration of the one or more sensors is based on a vehicle perception analysis;
- and
- the automated vehicle configured to:
- recalibrate one or more sensors of the automated vehicle in response to the distance-based differential exceeding the variation threshold.
One or more non-transitory computer-readable media storing processor-executable instructions that, when executed by at least one processor, cause the at least one processor to:
- identify a current trajectory of an automated vehicle based on a movement of the automated vehicle through a marshaling environment, wherein the current trajectory is based on a current location of the automated vehicle and a current speed of the automated vehicle;
- calculate a distance-based differential between the current trajectory of the automated vehicle and an expected trajectory of the automated vehicle, wherein the expected vehicle trajectory is based on a target path and a target vehicle speed;
- determine whether the distance-based differential exceeds a variation threshold;
- and
- recalibrate one or more sensors of an infrastructure system in response to the distance-based differential exceeding the variation threshold, wherein the recalibration of the one or more sensors is based on a vehicle perception analysis.
