Heads up display for a vehicle interior
First Claim
1. A heads up display system for a vehicle interior comprising:
- a light modifying panel configured to cyclically transition between a substantially light transmissive state that facilitates light passage through the light modifying panel and a partially reflective state that facilitates light reflection toward an occupant of a vehicle;
a pulsating light source configured to cyclically project an image onto the light modifying panel; and
a controller configured to control the pulsating light source and the light modifying panel;
wherein the controller, while the heads up display system is in use, is configured to transition the light modifying panel between the substantially light transmissive state and the partially reflective state at a target frequency, to instruct the pulsating light source to cyclically project the image at the target frequency, and to synchronize the cyclic projection of the pulsating light source with the cyclic transition of the light modifying panel such that the pulsating light source projects the image onto the light modifying panel only while the light modifying panel is in the partially reflective state.

Abstract
The present invention relates to a heads up display system for a vehicle interior that includes a light modifying panel configured to cyclically transition between a substantially light transmissive state that facilitates light passage through the light modifying panel and a partially reflective state that facilitates light reflection toward a occupant of a vehicle. The heads up display system also includes a pulsating light source configured to cyclically project an image onto the light modifying panel, and a controller configured to control the pulsating light source and the light modifying panel so that the image is projected onto the light modifying panel while the light modifying panel is in the partially reflective state.

10. A heads up display system for a vehicle interior comprising:
-
a light modifying panel configured to cyclically transition between a substantially light transmissive state that facilitates light passage through the light modifying panel and a partially reflective state that facilitates light reflection toward an occupant of a vehicle; a light source configured to shine an image at the light modifying panel; and a controller configured to control the state of the light modifying panel; wherein the controller is configured to output a signal to the light modifying panel to transition the light modifying panel between the substantially light transmissive state and the partially reflective state at a target frequency, and the controller is configured to control a reflectivity of the light modifying panel by adjusting a duty cycle of the signal. - View Dependent Claims (11, 12, 13)

14. A heads up display system for a vehicle interior comprising:
-
a pulsating light source configured to cyclically project an image onto a partially reflective surface; and a controller configured to control the pulsating light source, wherein the controller is configured to drive the pulsating light source at a first frequency during normal operation and to drive the pulsating light source at a second frequency in response to engaging an alert mode, the first frequency is greater than about 24 Hz, and the second frequency is about 17 Hz. - View Dependent Claims (15, 16, 17)
