1. A vision system for a vehicle comprising:
- a light source generating an illumination beam;
a receiver having a pixel array for capturing an image in response to at least a reflected portion of said illumination beam, said image corresponding to a first horizontal field of view (FOV) angle; and
a controller coupled to said light source and said receiver and receiving a vehicle speed input, said controller selecting a portion of said image as a non-linear function of said vehicle speed to generate a second horizontal FOV angle for displaying to the vehicle operator, wherein the second FOV angle is the same as the first FOV angle up to a low speed (LS) threshold value.

Abstract
A vision system for a vehicle includes a light source generating an illumination beam, a receiver having a pixel array for capturing an image in response to at least a reflected portion of the illumination beam, the image corresponding to a first horizontal field of view (FOV) angle, and a controller coupled to the light source and the receiver. The controller receives a vehicle speed input and, in response, selects a portion of the image as a non-linear function of the vehicle speed to generate a second horizontal FOV angle for displaying to the vehicle operator. The displayed angular FOV decreases, non-linearly, as the vehicle speed increases.

12. An active night vision system for a vehicle comprising:
-
a light source generating an illumination beam; vehicle sensors for indicating first and second vehicle operating parameters; a receiver having a pixel array for capturing an image in response to at least a reflected portion of said illumination beam, said image corresponding to a first horizontal field of view (FOV) angle; and a controller coupled to said light source, said receiver and said vehicle sensors, said controller selecting a portion of said image as a non-linear function of said first vehicle operating parameter and said second vehicle operating parameter to generate a second horizontal FOV angle for displaying to the vehicle operator, wherein said second horizontal FOV angle is the same as the first horizontal FOV angle up to a first threshold value related to said first or second vehicle operating parameters. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
