Systems and methods for vehicle side mirror control

1. A vehicle comprising:

a trailer sensor, a brake sensor, and a speed sensor;

a side mirror; and

a processor configured to:

set the side mirror in a first position responsive to determining via the trailer sensor and the speed sensor that a trailer is attached, and that a vehicle speed is above a non-zero threshold speed, respectively; and

transition the side mirror to a second position responsive to determining via the brake sensor that vehicle brakes have been applied for a non-zero threshold duration,

wherein the first position is a compact position and the second position is an extended position that is laterally outward of the first position,

wherein the processor is further configured to determine that the vehicle brakes have been released;

wherein the vehicle further comprises a traffic sensor configured to determine a characteristic of one or more nearby vehicles, wherein the processor is further configured to:

set the side mirror in the second position based on the characteristic.

2. The vehicle of claim 1 , wherein the processor is further configured to:

after waiting a predetermined period of time, responsively transition the side mirror to the first position.

3. The vehicle of claim 1 , wherein the processor is further configured to determine a side mirror characteristic corresponding to the second position based on input from a driver while the vehicle is in drive.

4. The vehicle of claim 3 , wherein the processor is further configured to modify the side mirror characteristic based on a current side mirror position.

5. The vehicle of claim 1 , wherein the processor is further configured to:

detect that a turn signal has been activated; and

responsively set the side mirror in the second position.

6. The vehicle of claim 5 , wherein the side mirror is a first side mirror, the vehicle further comprising a second side mirror, wherein the processor is further configured to set the first side mirror in the second position based on a side of the vehicle corresponding to the turn signal.

7. The vehicle of claim 1 , wherein the processor is further configured to:

detect an absolute steering wheel angle; and

transition the side mirror to the second position based on the absolute steering wheel angle.

8. A vehicle, comprising:

a trailer sensor, a brake sensor, and a speed sensor;

a side mirror; and

a processor configured to:

set the side mirror in a first position responsive to determining via the trailer sensor and the speed sensor that a trailer is attached, and that a vehicle speed is above a non-zero threshold speed, respectively; and

transition the side mirror to a second position responsive to determining via the brake sensor that vehicle brakes have been applied for a non-zero threshold duration,

wherein the processor is further configured to:

determine that the vehicle brakes have been applied greater than a threshold number of times in a threshold time period; and

responsively modify the non-zero threshold duration.

9. A method comprising:

determining, by a vehicle processor, that a trailer is attached;

determining, by the vehicle processor, that a vehicle speed is above a non-zero threshold speed;

responsively setting a side mirror in a first position;

determining that vehicle brakes have been applied for a non-zero threshold duration; and

responsively transitioning the side mirror to a second position,

wherein the first position is a compact position and the second position is an extended position that is laterally outward of the first position;

determining that the vehicle brakes have been released;

determining, by the vehicle processor, a characteristic of one or more nearby vehicles; and

setting the side mirror in the second position based on the characteristic.

10. The method of claim 9 , further comprising:

after waiting a predetermined period of time, responsively transitioning the side mirror to the first position.

11. The method of claim 9 , wherein the method further comprises:

determining a side mirror characteristic corresponding to the second position based on input from a driver while in drive.

12. The method of claim 11 , further comprising:

modifying the side mirror characteristic based on a current side mirror position.

13. The method of claim 9 , further comprising:

detecting that a turn signal has been activated; and

responsively setting the side mirror in the second position.

14. The method of claim 13 , wherein the side mirror is a first side mirror of a set comprising the first side mirror and a second side mirror, the method further comprising:

setting the first side mirror in the second position based on a side corresponding to the turn signal.

15. The method of claim 9 , further comprising:

detecting an absolute steering wheel angle; and

transitioning the side mirror to the second position based on the absolute steering wheel angle.

16. A method, comprising:

determining, by a vehicle processor, that a trailer is attached;

determining, by the vehicle processor, that a vehicle speed is above a non-zero threshold speed;

responsively setting a side mirror in a first position;

determining that vehicle brakes have been applied for a non-zero threshold duration;

responsively transitioning the side mirror to a second position;

determining that the vehicle brakes have been applied greater than a threshold number of times in a threshold time period; and

responsively modifying the non-zero threshold duration.

17. The vehicle of claim 1 , wherein, in the compact position, an outermost housing element of the side mirror is closer to a door of the vehicle, and in the extended position, the outermost housing element of the side mirror is displaced further away from the door.
