Rear camera backup assistance with touchscreen display using two points of interest

Abstract

Assistance for a backup maneuver of a motor vehicle in which a first point of interest on the vehicle is moved toward a second point of interest remote from the vehicle. A rear contextual view is displayed on an electronic display obtained from a rearward directed image sensor on the vehicle. A zoom window is manually placed on the electronic display to include the second point of interest. The zoom window is enlarged, and the location of the second point of interest is manually identified within the enlarged zoom window. The identified location of the second point of interest is transformed into target positional coordinates. The rear contextual view redisplayed with a target icon at the target positional coordinates. The location of the first point of interest is manually identified on the rear contextual view and transformed into starting positional coordinates. A start icon is displayed at the starting positional coordinates in the rear contextual view. A target line is determined between the target positional coordinates and the starting positional coordinates. A path line icon is displayed in the rear contextual view corresponding to the determined target line. A bearing line is displayed in the rear contextual view extending from the start icon. The target positional coordinates are re-determined as the rear contextual view shifts during the backup maneuver. The target icon and the path line icon are updated in response to the re-determined target positional coordinates.
