Navigating in snow
First Claim
1. A system for navigating a vehicle on a road with snow covering at least some lane markings and road edges, the system comprising:
- at least one processor programmed to;
receive from one or more image capture devices, a first environmental image forward of the vehicle and a second environmental image forward of the vehicle, the first environmental image and the second environmental image including areas where snow covers at least some lane markings and road edges, and wherein the first environmental image was captured using a first image capture parameter and the second environmental was captured using a second image capture parameter, the second image capture parameter being different from the first image capture parameter;
identify, based on an analysis of the first environmental image and the second environmental image, at least a portion of the road that is covered with snow and probable locations for road edges bounding the at least a portion of the road that is covered with snow; and
cause the vehicle to navigate a navigational path that includes the identified portion of the road and falls within the determined probable locations for the road edges.

Abstract
Systems and methods navigate a vehicle on a road with snow covering at least some lane markings and road edges. In one implementation, a system may include at least one processor programmed to receive from an image capture device, at least one environmental image forward of the vehicle, including areas where snow covers at least some lane markings and road edges, identify, based on an analysis of the at least one image, at least a portion of the road that is covered with snow and probable locations for road edges bounding the at least a portion of the road that is covered with snow, and cause the vehicle to navigate a navigational path that includes the identified portion of the road and falls within the determined probable locations for the road edges.
