First Claim
Patent Images
1. A method for use in a vehicle safety system for a host vehicle, the method comprising:
- processing host vehicle position and host vehicle movement to determine when the host vehicle is moving;
processing information from a forward looking camera system coupled to the host vehicle and configured to detect a first vehicle in a region in front of the host vehicle;
processing information from sensors configured to detect a second vehicle in an area behind the host vehicle, andwhen the host vehicle is moving, and the first vehicle is not detected in the region in front of the host vehicle,initiating an alert when the second vehicle is detected in the area behind the host vehicle.

19. A method for use in a vehicle safety system for a host vehicle, the method comprising:
-
obtaining a host vehicle position and a host vehicle movement; receiving, from a source of location information, high definition map data; processing high definition map data, host vehicle position and host vehicle movement to determine whether the host vehicle is moving in a passing lane; processing information from a forward looking camera system coupled to the host vehicle and configured to detect a first vehicle in a region in front of the host vehicle; processing information from sensors configured to detect a second vehicle in an area behind the host vehicle, and when the host vehicle is moving in a passing lane, and a first vehicle is not detected in the region in front of the host vehicle, initiating an alert when the second vehicle is detected in the area behind the host vehicle. - View Dependent Claims (20)
