Vision system for vehicle with adjustable cameras
First Claim
1. A vision system of a vehicle, said vision system comprising:
- a forward viewing imager disposed at a forward portion of a vehicle equipped with said vision system and having a forward field of view forward of the vehicle;
a rearward viewing imager disposed at a rearward portion of the vehicle and having a rearward field of view rearward of the vehicle;
sideward viewing imagers disposed at respective side portions of the vehicle and having respective sideward fields of view sideward of the vehicle at the respective side of the vehicle at which said sideward viewing imagers are disposed;
wherein at least one of (i) the forward field of view of said forward viewing imager is dynamically adjustable responsive to a vehicle input, (ii) the rearward field of view of said rearward viewing imager is dynamically adjustable responsive to a vehicle input and (iii) the sideward fields of view of said sideward viewing imagers are dynamically adjustable responsive to a vehicle input;
wherein, responsive to the vehicle input being indicative of one of (i) rearward travel of the vehicle and (ii) traveling speed of the vehicle being less than a first threshold level, the field of view of at least one of said imagers is adjusted to encompass a ground region immediately adjacent the portion of the vehicle at which said at least one of said imagers is disposed;
wherein, when the field of view of said at least one of said imagers is adjusted to encompass the respective ground region, said vision system uses image data captured by at least some of said imagers for displaying a surround view of the vehicle derived at least in part from image data captured by at least some of said imagers;
wherein, responsive to the vehicle input being indicative of forward traveling speed of the vehicle being greater than a second threshold level, the field of view of said at least one of said imagers is adjusted to encompass a distant region further away from the vehicle compared to the respective ground region; and
wherein, when the field of view of said at least one of said imagers is adjusted to encompass the respective distant region, said vision system processes image data captured by said at least one of said imagers for a collision avoidance system.

Abstract
A vision system of a vehicle includes a forward viewing imager, a rearward viewing imager and sideward viewing imagers. The forward viewing imager is disposed at a forward portion of the vehicle and has a forward field of view. The rearward viewing imager is disposed at a rearward portion of the vehicle and has a rearward field of view rearward of the vehicle. The sideward viewing imagers are disposed at respective sides of the vehicle and have respective sideward fields of view sideward of the vehicle. At least one of the forward viewing imager, the rearward viewing imager and the sideward viewing imagers is dynamically adjustable via a respective stepper motor. The fields of view of the imagers may be adjustable via the respective stepper motors responsive to actuation of a user input and/or a speed input indicative of the traveling speed of the vehicle.

13. A vision system of a vehicle, said vision system comprising:
-
a forward viewing imager disposed at a forward portion of a vehicle equipped with said vision system and having a forward field of view forward of the vehicle; a rearward viewing imager disposed at a rearward portion of the vehicle and having a rearward field of view rearward of the vehicle; sideward viewing imagers disposed within respective exterior rearview mirror assemblies at respective side portions of the vehicle, wherein said sideward viewing imagers have respective sideward fields of view sideward of the vehicle at the respective side of the vehicle at which said sideward viewing imagers are disposed; wherein (i) the field of view of said forward viewing imager is dynamically adjustable to vertically adjust the field of view of said forward viewing imager, (ii) the field of view of said rearward viewing imager is dynamically adjustable to vertically adjust the field of view of said rearward viewing imager and (iii) the respective fields of view of said sideward viewing imagers are dynamically adjustable to vertically adjust the fields of view of said sideward viewing imagers; wherein, responsive to the vehicle input being indicative of one of (i) rearward travel of the vehicle and (ii) traveling speed of the vehicle being less than a first threshold level, said imagers are adjusted to a first orientation and are operable to capture image data for use in displaying a surround view of the vehicle derived at least in part from image data captured by said imagers; wherein, responsive to the vehicle input being indicative of forward traveling speed of the vehicle being greater than a second threshold level, said imagers are adjusted to a second orientation and are operable to capture image data for use in a collision avoidance system; and wherein, when in the first orientation, the fields of view of said imagers encompass respective ground areas immediately adjacent the respective portions of the vehicle at which said imagers are disposed, and wherein, when in the second orientation, the fields of view of said imagers encompass respective distant regions further away from the vehicle compared to the respective ground areas. - View Dependent Claims (14)
