Abstract
A method for assisting the operation of a host vehicle traveling on a roadway includes acquiring images around the host vehicle with at least one primary camera assembly having a first field of view. Visibility is detected within the first field of view. The at least one primary camera assembly is deactivated when the detected visibility is below a predetermined value. Images are acquired around the host vehicle with at least one secondary camera assembly having a second field of view until the detected visibility in the first field of view is at or above the predetermined value.

A method for assisting operation of a host vehicle traveling on a roadway, comprising:
- acquiring images around the host vehicle with at least one primary camera assembly having a first field of view;
- detecting visibility within the first field of view;
- deactivating the at least one primary camera assembly when the detected visibility is below a predetermined value;
- and
- acquiring images around the host vehicle with at least one secondary camera assembly having a second field of view until the detected visibility in the first field of view is at or above the predetermined value.
A vehicle assist system for a host vehicle traveling on a roadway, comprising:
- at least one primary camera assembly for acquiring images around the host vehicle in a first field of view;
- at least one secondary camera assembly for acquiring images around the host vehicle in a second field of view;
- a sensor for detecting light within the first field of view;
- a controller connected to the at least one primary camera assembly, the at least one secondary camera assembly, and the light sensor, wherein the controller relies only on the at least one primary camera assembly to acquire images around the host vehicle when the detected light intensity within the first field of view is below a predetermined value, the controller relying only on the at least one secondary camera assembly to acquire images around the host vehicle when the detected light intensity in the first field of view is at or above the predetermined value.
