Abstract
Methods and systems for controlling a sunshade of a vehicle. The methods and systems receive a route plan from a first location to a second location, predict a sun parameter indicative of sun glare on the window for the route plan based on solar direction and vehicle heading at distributed locations throughout the route plan, and activate the sunshade based on the sun parameter so as to shade the window.
Claims18
A vehicle, comprising:
- a sunshade for a window capable of being automatically activated to shade the window and deactivated to unshade the window;
- at least one processor in operable communication with the sunshade, wherein the at least one processor is configured to execute program instructions, wherein the program instructions are configured to cause the at least one processor to:
- receive a route plan from a first location to a second location;
- predict a sun parameter indicative of sun glare on the window for the route plan based on solar direction and vehicle heading at distributed locations throughout the route plan, wherein the program instructions are configured to cause the at least one processor to predict the sun parameter by:
- dividing the route plan into segments;
- calculating, for each segment, an amount of time sun is facing an occupant based on vehicle heading, solar direction, location of the window, nominal location of the occupant, and driving time for the segment, wherein the driving time for the segment is calculated based on predicted speed and length of the segment;
- and
- totaling the amounts of time the sun is facing the occupant for each segment;
- and
- activate the sunshade based on the sun parameter.

A method of controlling a sunshade of a vehicle, the method comprising:
- receiving, via at least one processor, a route plan from a first location to a second location;
- predicting, via the at least one processor, a sun parameter indicative of sun glare on the window for the route plan based on solar direction and vehicle heading at distributed locations throughout the route plan, wherein predicting the sun parameter is performed by:
- dividing the route plan into segments;
- calculating, for each segment, an amount of time sun is facing the driver based on vehicle heading, solar direction, location of the window, nominal location of an occupant, and driving time for the segment, wherein the driving time for the segment is calculated based on predicted speed and length of the segment;
- and
- totaling the amounts of time the sun is facing the driver for each segment;
- and
- activating, via the at least one processor, the sunshade based on the sun parameter so as to shade the window.
