Abstract

A sensor pod system includes one or more sensor pods with a plurality of sensors configured to collect data from an environment. A sensor pod may have an effective field of view created by individual sensors with overlapping fields of view. The sensor pod system may include sensors of different types and modalities. Sensor pods of the sensor pod system may be modularly disposed on a vehicle, for example, an autonomous vehicle to collect and provide data of the environment during operation of the vehicle. The sensor pods may be disposed at elevated locations around the vehicle to reduce obstacles within the sensor pods fields of view.

First claim

What is claimed is:

1. A vehicle comprising:
a body having a first end and a second end distal to the first end along a longitudinal axis;
a first sensor pod, comprising multiple sensors disposed in a first sensor pod housing, the first sensor pod removably coupled to the body at a first location, the first location adjacent to the first end spaced from the longitudinal axis in a first direction along a first transverse axis, at an elevation above a ground interface;
a second sensor pod, comprising multiple sensors disposed in a second sensor pod housing, the second sensor pod removably coupled to the body at a second location, the second location adjacent to the first end spaced from the longitudinal axis in a second direction, opposite the first direction along the first transverse axis, at the elevation;
a third sensor pod, comprising multiple sensors disposed in a third sensor pod housing, the third sensor pod removably coupled to the body at a third location, the third location adjacent to the second end spaced from the longitudinal axis in the first direction, along a second transverse axis, at the elevation; and
a fourth sensor pod, comprising multiple sensors disposed in a fourth sensor pod housing, the fourth sensor pod removably coupled to the body at a fourth location, the fourth location adjacent to the second end spaced from the longitudinal axis in the second direction, opposite the first direction along the second transverse axis, at the elevation, wherein:
the first sensor pod has a first effective sensor field of view of at least 260 degrees and less than 360 degrees about an exterior of the body, wherein the first effective field of view comprises a first continuous and unobstructed view of a first lateral side of the body and the first end;
the second sensor pod has a second effective sensor field of view of at least 260 degrees and less than 360 degrees about the exterior of the body, wherein the second effective field of view comprises a second continuous and unobstructed view of the first lateral side and the second end;
the third sensor pod has a third effective sensor field of view of at least 260 degrees and less than 360 degrees about the exterior of the body, wherein the third effective field of view comprises a third continuous and unobstructed view of the first end and a second lateral side of the body;
the fourth sensor pod has a fourth effective sensor field of view of at least 260 degrees and less than 360 degrees about the exterior of the body, wherein the fourth effective field of view comprises a fourth continuous and unobstructed view of the second lateral side and the second end;
the first effective sensor field of view overlapping with at least a portion of the second effective sensor field of view capturing the first lateral side and with at least a portion of the third effective sensor field of view capturing the first end, wherein the first lateral side is adjacent to the first end;
the second effective sensor field of view overlapping with at least a portion of the first effective sensor field of view capturing the first lateral side and with at least a portion of the fourth effective sensor field of view capturing the second end, wherein the first lateral side is adjacent to the second end;
the third effective sensor field of view overlapping with at least a portion of the first effective sensor field of view capturing the first end and with at least a portion of the fourth effective sensor field of view capturing the second lateral side, wherein the second lateral side is adjacent to the first end;
the fourth effective sensor field of view overlapping with at least a portion of the second effective sensor field of view capturing the second end and with at least a portion of the third effective sensor field capturing the second lateral side, wherein the second lateral side is adjacent to the second end; and
the first sensor pod, second sensor pod, third sensor pod, and the fourth sensor pod are each mounted to a respective arm extending from the exterior of the vehicle such that the first sensor pod, second sensor pod, third sensor pod, and the fourth sensor pod extend beyond a periphery of the body.

2. The vehicle of claim 1 , wherein each respective arm extends for a substantially similar distance from a different corner of the body and substantially oblique to any side of the vehicle.

3. The vehicle of claim 1 , wherein three of the first effective sensor field of view, the second effective sensor field of view, the third effective sensor field of view, or the fourth effective sensor field of view collectively provide an effective vehicle field of view of 360 degrees at a first distance from the vehicle.

4. The vehicle of claim 1 , wherein each of the first sensor pod, the second sensor pod, the third sensor pod, and the fourth sensor pod protrude at least an eight inch distance from a longitudinal end and at least an eight inch distance from a lateral side at a different respective corner of the body of the vehicle.

5. The vehicle of claim 1 , further comprising an additional sensor disposed on the body separate from the first sensor pod, the second sensor pod, the third sensor pod, and the fourth sensor pod,
wherein the additional sensor has a fifth field of view, which overlaps with at least a portion of two of the first effective sensor field of view, the second effective sensor field of view, the third effective sensor field of view, or the fourth effective sensor field of view.

6. The vehicle of claim 1 , wherein the first location is within a first distance of the first end and the spacing from the longitudinal axis of the first location is greater than a second distance from the longitudinal axis, such that the effective sensor field of view of the first sensor pod includes a view of an object behind an obstacle located at a first position relative to and spaced from the vehicle.

7. The vehicle of claim 1 , wherein the respective arm is attached to the body and extends through a panel of the body.

8. The vehicle of claim 1 , wherein the first effective sensor field of view, the second effective sensor field of view, the third effective sensor field of view, and the fourth effective sensor field of view each comprise a camera field of view.

9. The vehicle of claim 1 , wherein the first sensor pod, the second sensor pod, the third sensor pod, and the fourth sensor pod are each mounted below a roof of the vehicle.

10. The vehicle of claim 1 , wherein:
the first effective sensor field of view comprises a first field of view of a first sensor of the multiple sensors disposed in the first sensor pod having a first optical axis substantially perpendicular to the first lateral side and a second field of view associated with a second sensor of the multiple sensors disposed in the first sensor pod having a second optical axis substantially perpendicular to the first end;
the second effective sensor field of view comprises a third field of view of a first sensor of the multiple sensors disposed in the second sensor pod having a third optical axis substantially perpendicular to the first lateral side and a fourth field of view associated with a second sensor of the multiple sensors disposed in the second sensor pod having a fourth optical axis substantially perpendicular to the second end;
