Abstract

A method including receiving a first position of a sun visor of a vehicle; receiving a route of the vehicle from a navigation system of the vehicle, the route having at least one waypoint; determining a predicted amount of sunlight in an occupant's eyes at the at least one waypoint of the route; determining whether the predicted amount of sunlight in the occupant's eyes at the at least one waypoint of the route is greater than a predefined threshold amount; and instructing the sun visor to move to a second position in response to the predicted amount of sunlight exceeding the predefined threshold amount to block at least a portion of the predicted amount of sunlight from the occupant's eyes at the at least one waypoint is disclosed.

First claim

What is claimed is:

1 . A method comprising:
receiving a first position of a sun visor of a vehicle; receiving a route of the vehicle from a navigation system of the vehicle, the route having a starting point and at least one waypoint after the starting point; determining a predicted amount and angle of sunlight in an occupant's eyes at the at least one waypoint of the route based on the route and predicted sun at the waypoint; determining that the predicted amount of sunlight in the occupant's eyes at the at least one waypoint of the route is greater than a predefined threshold amount; and instructing the sun visor to move to a second position while the vehicle is along the route after the starting position in response to the predicted amount of sunlight exceeding the predefined threshold amount to block at least a portion of the predicted amount of sunlight from the occupant's eyes at the at least one waypoint.

2 . The method of claim 1 , further comprising activating at least one motor to automatically adjust the sun visor to the second position as the vehicle approaches the at least one waypoint of the route.

3 . The method of claim 2 , wherein the activating the at least one motor to automatically adjust the sun visor to the second position occurs in response to the vehicle being within a predetermined timing threshold of the at least one waypoint of the route.

4 . The method of claim 3 , wherein the predetermined timing threshold is 30 seconds.

5 . The method of claim 1 , wherein the determining the predicted amount of sunlight in the occupant's eyes includes:
determining a direction of the vehicle at the at least one waypoint of the route; and determining an angle in which the sun is positioned to the occupant's eyes based on a predicted position of the sun and the direction of the vehicle.

6 . The method of claim 1 , further comprising receiving an indication of an amount of sunlight entering the vehicle and a sun path from a sun sensor.

7 . The method of claim 6 , further comprising receiving a gaze detection from an interior camera, the gaze detection indicating a location of the occupant's eyes relative to the sun visor and the sun path.

8 . The method of claim 6 , wherein the sun sensor includes a light brightness detector.

9 . The method of claim 1 , further comprising:
receiving a first position of a second sun visor of the vehicle separate and distinct from the sun visor; determining a second predicted amount of sunlight in a second occupant's eyes at the at least one waypoint of the route; determining whether the predicted amount of sunlight in the second occupant's eyes at the at least one waypoint of the route is greater than the predefined threshold amount; and instructing the second sun visor to move to a second position in response to the second predicted amount of sunlight exceeding the predefined threshold amount to block at least a portion of the second predicted amount of sunlight from the second occupant's eyes at the at least one waypoint.

10 . The method of claim 9 , wherein the second sun visor is arranged on a headliner of the vehicle.

11 . An active dynamic sun visor system, comprising:
a sun visor having a motor to automatically adjust the position of the sun visor; a driver camera configured to detect the gaze of an occupant of a vehicle; a front sensor configured to detect brightness of sunlight on a windshield of the vehicle; and a controller configured to:
receive a route of the vehicle from a navigation system of the vehicle, the route having a starting point and at least one waypoint after the starting point;
receive the gaze and determine a location of an occupant's eyes relative to the sun visor;
receive the detected brightness from the front sensor;
determine an amount of sunlight in the occupant's eyes based at least in part on the detected brightness of sunlight from the front sensor and the location of the occupant's eyes;
instruct the motor of the sun visor to alter the position of the sun visor in response to the amount of sunlight in the occupant's eyes exceeding a predetermined threshold;
calculate a future amount of sunlight in the occupant's eyes at the at least one waypoint of the route after a starting position based on the route and future amount of sunlight at the waypoint and determine whether the future amount of sunlight at the waypoint is greater than the predetermined threshold; and
instruct the sun visor to move to a second position while the vehicle is along the route after the starting position in response to the future amount of sunlight exceeding the predefined threshold amount to block at least a portion of the future amount of sunlight from the occupant's eyes at the at least one waypoint.

12 . The active dynamic sun visor system of claim 11 , wherein the controller determines a present amount of sun in the occupant's eyes when the sun visor is at the second position using the at least one signal from the driver camera and the at least one signal from the front sensor.

13 . The active dynamic sun visor system of claim 11 , further comprising a temperature gauge, wherein the controller is configured to receive a temperature of the vehicle from the temperature gauge.

14 . The active dynamic sun visor system of claim 13 , wherein the controller determines a present temperature of the vehicle is greater than a predetermined threshold temperature, the controller sends control information to the sun visor to move into a fully extended position.

15 . The active dynamic sun visor system of claim 11 , further comprising:
a second sun visor; and a second motor configured to control the position of the second sun visor and to receive control information from the controller.

16 . The active dynamic sun visor system of claim 15 , wherein the controller is programmed to
determine a second position of the second sun visor where the amount of sunlight in the occupant's eyes is less than the predetermined threshold; transmit control information to the second motor to move the second sun visor to the second position; and determine a present amount of sun in the occupant's eyes when the second sun visor is at the second position using the at least one signal from the driver camera and the at least one signal from the front sensor.

17 . The active dynamic sun visor system of claim 15 , wherein the second sun visor is arranged on a headliner of the vehicle.

18 . The active dynamic sun visor system of claim 11 , wherein the controller is configured to activate at least one motor to automatically adjust the sun visor to the second position as the vehicle approaches the at least one waypoint of the route.

19 . The active dynamic sun visor system of claim 18 , wherein the controller is configured to activate the at least one motor to automatically adjust the sun visor to the second position occurs in response to the vehicle being within a predetermined timing threshold of the at least one waypoint of the route.
