Abstract

Method and apparatus are disclosed for facilitating active protection of peripheral sensors. An example vehicle includes a sensor and a sensor protector. The example sensor protector is configured to, responsive to a vehicle collision, obtain diagnostic information from the sensor. The example sensor protector is also configured to determine whether to move the sensor from a first position to a second position based on the diagnostic information. The example sensor protector is also configured to cause the sensor to from the first position to the second position based on the determination.

First claim

What is claimed is:

1. A vehicle comprising:
a sensor; and
a sensor protector to:
detect an impending collision;
move the sensor from a second position to a first position prior to the detected impending collision occurring, wherein the second position is at a periphery of the vehicle, and wherein the first position is located behind a fascia of the vehicle;
obtain, based on a determination that the collision has taken place, diagnostic information from the sensor;
determine that the sensor is physically capable of moving back from the first position to the second position based on the diagnostic information; and
cause the sensor to move from the first position to the second position based on the determination.

2. The vehicle of claim 1 , wherein the diagnostic information includes at least one of: whether a sensor protection mechanism was triggered for the sensor, whether the sensor is disconnected or experiencing an electrical issue, whether an actuator associated with the sensor was triggered, whether the sensor moved from the second position to the first position, position information of the sensor, orientation information of the sensor, and proximity information of the sensor.

3. The vehicle of claim 1 , further including an actuator coupled to the sensor, and wherein the actuator is communicatively coupled to the sensor protector.

4. The vehicle of claim 3 , wherein the sensor protector is to cause the actuator to cause the sensor to move from the first position to the second position.

5. The vehicle of claim 3 , wherein the actuator is an electric actuator.

6. The vehicle of claim 1 , wherein the sensor protector is to move the sensor from the second position to the first position by rotating the sensor away from a periphery of the vehicle.

7. The vehicle of claim 1 , wherein the sensor protector is to move the sensor from the second position to the first position by retracting the sensor away from a periphery of the vehicle.

8. A method comprising:
detecting, via a processor of a vehicle, an impending collision;
moving a sensor of the vehicle from a second position to a first position prior to the detected impending collision occurring, wherein the second position is at a periphery of the vehicle and wherein the first position is located behind a fascia of the vehicle;
detecting that the collision associated with the vehicle occurred;
obtaining, via the processor and based on a determination that the collision has taken place, diagnostic information from a sensor;
determining, via the processor, that the sensor is physically capable of moving back from the first position to the second position based on the diagnostic information; and
causing the sensor to move from the first position to the second position based on the determination.

9. The method of claim 8 , wherein the diagnostic information includes at least one of: whether a sensor protection mechanism was triggered for the sensor, whether the sensor is disconnected or experiencing an electrical issue, whether an actuator associated with the sensor was triggered, whether the sensor moved from the second position to the first position, position information of the sensor, orientation information of the sensor, and proximity information of the sensor.

10. The method of claim 8 , further including causing, via the processor, an actuator to cause the sensor to move from the first position to the second position, wherein the actuator is coupled to the sensor.

11. The method of claim 8 , wherein the moving of the sensor from the second position to the first position includes rotating the sensor away from a periphery of the vehicle.

12. The method of claim 8 , wherein the moving of the sensor from the second position to the first position includes retracting the sensor away from a periphery of the vehicle.
