Abstract

A multi-purpose exterior mirror module for a vehicle comprising an image sensor configured to capture image data and a reflective surface disposed on a side portion. A housing is configured to support the reflective surface and the image sensor in connection with the vehicle. An actuator is configured to adjust an orientation of the reflective surface about an adjustment axis. A controller is in communication with the image sensor and the actuator. The controller is configured to control the actuator to adjust an orientation of the reflective surface about the adjustment axis.

Claims

1. An exterior mirror module for a vehicle comprising:

an image sensor configured to capture image data;

a reflective element disposed on a first side portion;

a housing configured to support the reflective element and the image sensor in connection with the vehicle;

an actuator configured to adjust an orientation of the reflective element about an adjustment axis; and

a controller in communication with the image sensor and the actuator, wherein the controller is configured to control the actuator to adjust an orientation of the reflective element about the adjustment axis between a first orientation and a second orientation, wherein the first orientation comprises a reflective surface of the reflective element orientated such that light received from a rearward direction of the vehicle is reflected into a passenger compartment of the vehicle and the second orientation comprises the reflective surface of the reflective element directed toward at least one of an opening surface of the vehicle and a skyward direction normal to the operating surface.

2. The module according to claim 1, wherein the housing comprises a height corresponding to the reflective element, a width extending away from the vehicle, and a depth.

3. The module according to claim 2, wherein the adjustment axis extends substantially along the width of the housing.

4. The module according to claim 2, wherein the controller is configured to adjust an orientation of the housing and the reflective element such that the height and depth of the housing are rotated about the adjustment axis.

5. The module according to claim 1, wherein the actuator is configured to adjust the orientation of the reflective element while maintaining an orientation of the image sensor.

6. The module according to claim 1, wherein the adjustment of the orientation of the reflective element comprises a rotation of at least 60 degrees about the adjustment axis.

7. The module according to claim 1, wherein the first orientation forms a first profile shape directed in a forward operating direction of the vehicle and the second orientation forms a second profile shape directed in the forward operating direction of the vehicle relative to the forward operating direction.

8. The module according to claim 7, wherein the second profile shape is at least 20% smaller in a frontal surface area relative to the first profile shape, wherein the frontal surface area is perpendicular to a forward operating direction.

9. The module according to claim 7, wherein the second profile shape is at least 40% smaller in a frontal surface area relative to the first profile shape, wherein the frontal surface area is perpendicular to a forward operating direction.

10. A method for controlling an exterior mirror assembly for a vehicle, the method comprising:

orienting the mirror assembly in a first orientation about an adjustment axis;

exposing a first surface of the mirror assembly in an airflow direction generated by a forward motion of the vehicle;

controlling a rotation of the mirror assembly by at least 60 degrees about the adjustment axis in a second orientation; and

exposing a second surface of the mirror assembly in the airflow direction generated by the forward motion, wherein the second surface comprises a frontal area at least 10 percent smaller than the first surface, wherein the controlling the rotation of the mirror assembly rotates the first surface from a frontal surface of the vehicle in the first orientation presenting the second surface as the frontal surface of the vehicle in the second orientation.

11. The method according to claim 10, further comprising:

maintaining an orientation of a camera in connection with the mirror assembly in a fixed orientation while the mirror assembly is rotated.

12. The method according to claim 11, further comprising:

displaying image data captured in a rearward directed field of view via the camera on a display in the vehicle.

13. The method according to claim 10, further comprising:

wherein the controlling the rotation of the mirror assembly is configured to reduce the frontal area of the vehicle.

14. The method according to claim 10, wherein the first orientation comprises a reflective surface of the mirror assembly oriented such that light received from a rearward direction of the vehicle is reflected into a passenger compartment of the vehicle.

15. The method according to claim 10, wherein the second orientation comprises the reflective surface directed toward at least one of an operating surface of the vehicle and a skyward direction normal to the operating surface.

16. An exterior mirror module for a vehicle comprising:

an image sensor configured to capture image data;

a mirror assembly comprising a housing configured to support a reflective element and the image sensor;

an actuator configured to adjust an orientation of the mirror assembly relative to the vehicle about an adjustment axis; and

a controller in communication with the image sensor and the actuator, wherein the controller is configured to control the actuator to adjust an orientation of the reflective element about the adjustment axis from a first orientation to a second orientation, wherein the first orientation comprises a first surface of the mirror assembly oriented as a frontal surface relative to a forward operation of the vehicle and the second orientation comprises a second surface of the mirror assembly oriented as the frontal surface, wherein the second surface comprises a reduced drag coefficient relative to the first surface.
