Sensor assemblies and object detection in vehicles

1. A vehicle comprising:

a vehicle body; and

at least one sensor assembly supported on the vehicle body and configured to detect an external object, the at least one sensor assembly including:

a housing portion; and

a sensor defining a central axis and supported within the housing portion such that the central axis of the sensor is oriented at a fixed, non-adjustable downward angle in relation to a longitudinal axis of the vehicle.

2. The vehicle of claim 1 , wherein the at least one sensor assembly is supported on a rear end portion of the vehicle.

3. The vehicle of claim 2 , wherein the vehicle further includes a rear bumper, the at least one sensor assembly being supported vertically above the rear bumper.

4. The vehicle of claim 2 , wherein the vehicle further includes a rear bumper, the at least one sensor assembly being supported on the rear bumper.

5. The vehicle of claim 1 , wherein the at least one sensor assembly is supported on the vehicle body such that the fixed, non-adjustable downward angle lies substantially within a range of approximately 15° to approximately 45°.

6. The vehicle of claim 5 , wherein the at least one sensor assembly is supported on the vehicle body such that the fixed, non-adjustable downward angle is approximately 30°.

7. The vehicle of claim 1 , wherein the at least one sensor assembly includes:

a first sensor assembly spaced from a first lateral end of the vehicle; and

a second sensor assembly spaced from a second lateral end of the vehicle.

8. The vehicle of claim 7 , wherein the first sensor assembly is spaced a first distance from the first lateral end of the vehicle and the second sensor assembly is spaced a second distance from the second lateral end of the vehicle, the first distance and the second distance being approximately equivalent.

9. The vehicle of claim 7 , wherein the at least one sensor assembly further includes:

a third sensor assembly spaced between the first sensor assembly and the second sensor assembly; and

a fourth sensor assembly spaced between the second sensor assembly and the third sensor assembly.

10. The vehicle of claim 1 , wherein the at least one sensor assembly further includes:

a retaining member extending laterally outward from the housing portion; and

a collar supported adjacent to an end of the housing portion so as to define a receiving space between the retaining member and the collar configured to receive the vehicle body such that the vehicle body is located between the retaining member and the collar to thereby secure the at least one sensor assembly in relation to the vehicle body.

11. The vehicle of claim 10 , wherein the at least one sensor assembly includes an indicator to facilitate proper orientation of the at least one sensor assembly in relation to the vehicle body during installation.

12. The vehicle of claim 10 , wherein the housing portion defines an opening configured to receive a locking member to further secure the at least one sensor assembly in relation to the vehicle body.

13. A vehicle comprising:

a vehicle body; and

at least one sensor assembly supported on the vehicle body, the at least one sensor assembly including:

a housing portion including:

a trunk extending along a first axis; and

a receptacle extending into the trunk along a second axis oriented at a fixed angle in relation to the first axis; and

a sensor supported within the receptacle such that the sensor is oriented at a downward angle in relation to a length of the vehicle, the sensor being configured to detect an external object.

14. The vehicle of claim 13 , wherein the receptacle extends into the trunk such that the fixed angle is approximately 30°.

15. The vehicle of claim 13 , wherein the at least one sensor assembly includes a plurality of sensor assemblies spaced approximately equidistant from each other.

16. The vehicle of claim 13 , wherein the at least one sensor assembly is supported on a rear end portion of the vehicle.

17. The vehicle of claim 13 , wherein the at least one sensor assembly further includes:

a deflectable retention member extending laterally outward from the housing portion; and

a collar supported adjacent to an end of the housing portion such that the vehicle body is received between the deflectable retention member and the collar during installation of the at least one sensor assembly to thereby secure the at least one sensor assembly in relation to the vehicle body.

18. A vehicle comprising:

a vehicle body; and

at least one sensor assembly supported on the vehicle body, the at least one sensor assembly including:

a housing portion defining a receptacle with one or more recesses; and

a sensor supported within the receptacle such that the sensor is oriented at a downward angle in relation to a length of the vehicle, the sensor being configured to detect an external object and including one or more anchors positioned within the one or more recesses.

19. The vehicle of claim 18 , wherein the one or more anchors are resilient in construction and reconfigurable between an expanded configuration, in which the one or more anchors are positioned within the one or more recesses to thereby secure the sensor within the receptacle, and a compressed configuration, in which the one or more anchors are deflected inwardly to allow for removal of the sensor from the receptacle.

20. The vehicle of claim 19 , wherein the one or more anchors each include a chamfered surface configured for contact with the housing portion to facilitate reconfiguration of the one or more anchors from the expanded configuration into the compressed configuration during insertion of the sensor into the receptacle.
