Abstract

A system for enabling a driver of a vehicle to visibly observe objects located in a blind spot includes, but is not limited to, a rear view viewing device that is mounted to the vehicle and configured to be electronically adjustable. The system further includes a sensor that is associated with the vehicle and that is configured to detect a location of an object with respect to the vehicle and to generate a first signal indicative of the location of the object. The system further includes a processor that is communicatively coupled with the sensor and that is operatively coupled with the rear view viewing device. The processor is configured to obtain the first signal from the sensor and to command the rear view viewing device to adjust such that the object is visibly observable to the driver when the processor receives the first signal.

Claims

1. A system for enabling a driver of a vehicle to visibly observe objects located in a blind spot, the system comprising:

a mirror assembly mounted to the vehicle and configured to be electronically adjustable;

a first sensor associated with the vehicle and configured to detect a location of an object with respect to the vehicle and to generate a first signal indicative of the location of the object;

a second sensor associated with the mirror assembly and configured to detect an orientation of a reflective surface of the mirror assembly and to generate a second signal indicative of the orientation of the reflective surface; and

a processor communicatively coupled with the first sensor and the second sensor and operatively coupled with the mirror assembly, the processor configured to obtain the first signal from the first sensor, to obtain the second signal from the second sensor, to determine a field of view of the driver based on the orientation of the reflective surface, to determine whether the object falls within the field of view based on the location of the object, to command the mirror assembly to adjust the orientation of the reflective surface such that the object enters the field of view when the processor determines that the object falls outside of the field of view, and to command the mirror assembly to adjust the orientation of the reflective surface by an amount that varies in a manner that directly corresponds with the location of the object within the blind spot such that the reflective surface moves as minimally as necessary to cause a portion of the object to enter the field of view, the portion of the object being less than an entirety of the object.

2. The system of claim 1, wherein the first sensor comprises a radar emitter.

3. The system of claim 1, further comprising an actuator communicatively coupled with the processor, the actuator configured to generate a third signal when actuated, wherein the processor is further configured to obtain the third signal from the actuator and to command the mirror assembly to adjust the orientation of the reflective surface when the processor receives the first signal, the second signal, and the third signal.

4. The system of claim 3, wherein the actuator comprises the second sensor.

5. The system of claim 3, wherein the actuator comprises a driver input unit.

6. The system of claim 3, wherein the actuator comprises a turn signal sensor.

7. The system of claim 3, wherein the actuator comprises a steering wheel sensor.

8. The system of claim 3, wherein the actuator comprises a lane departure sensor.

9. The system of claim 1, further comprising a third sensor communicatively coupled with the processor and configured to detect a location of an eye of the driver and to generate a third signal indicative of the location of the eye of the driver, the processor further configured to obtain the third signal from the third sensor and to determine the field of view of the driver based on the location of the eye of the driver.

10. A method for enabling a driver of a vehicle to visibly observe objects located in a blind spot, the method comprising the steps of:

detecting, with a first sensor, an orientation of a reflective surface of a mirror assembly of the vehicle;

detecting, with a second sensor, a location of an object with respect to the vehicle;

detecting, with a third sensor, a location of an eye of the driver;

calculating, with a processor, a field of view of the driver based on the orientation of the reflective surface and the location of the eye of the driver;

determining, with the processor, whether the object is located within the field of view based on the location of the object and the field of view; and

adjusting the orientation of the reflective surface by an amount that varies in a manner that directly corresponds with the location of the object within the blind spot such that the reflective surface moves as minimally as necessary to cause a portion of the object to enter the field of view when the object is located outside of the field of view, the portion of the object being less than an entirety of the object.

11. The method of claim 10, further comprising the step of receiving an actuation signal and wherein the step of adjusting the orientation of the reflective surface comprises adjusting the orientation of the reflective surface when the actuation signal is received.

12. The method of claim 10, further comprising the step of restoring the orientation of the reflective surface after a predetermined period of time.
