Vehicle vision system with blind zone display and alert system

Abstract

A vision system for a vehicle includes an exterior structure mounted at an exterior portion of a body side of the equipped vehicle, with an imaging sensor disposed at the exterior structure and having a field of view exterior and sideward and rearward of the vehicle. A video display screen is disposed in an interior cabin of the equipped vehicle and operable to display video images. Responsive to detection of another vehicle at or near the side of the equipped vehicle, said video display screen displays a graphic overlay at the display screen. The graphic overlay includes a semitransparent overlay having a longitudinally extending line segment that extends along a displayed body side portion of the equipped vehicle and a plurality of laterally extending line segments that extend laterally outwardly from the longitudinally extending line segment at spaced apart intervals along the longitudinally extending line segment.

AI Technical Summary

Benefits of technology

[0005]The present invention provides a vision system for displaying video images of a side region or blind spot region at the side of the vehicle for viewing by the driver of the vehicle. Optionally, a video display screen may be disposed in the vehicle cabin and generally at or mounted at an inside portion of the vehicle door. Optionally, a video display screen may be disposed at a wide angle spotter mirror location (such as at an upper outboard corner region) of the reflective element of the exterior rearview mirror assembly mounted at the exterior side of the vehicle. The video display screen displays video images captured by the exterior viewing camera and provides a graphic overlay at the displayed images, with the graphic overlay extending perspectively along the side region of the vehicle with indications (such as short laterally extending portions or segments or different shadings or colors or the like) to show distance of objects or vehicles from the vehicle (such as both laterally from the vehicle and rearwardly of the vehicle). The displayed graphic overlay thus provides enhanced cognitive awareness for the driver in understanding the distance of the vehicles present in the camera's field of view.

Problems solved by technology

It is known to provide an object in a blind spot detection / LCA system for a vehicle that detects the presence of another vehicle or object in the lane next to the host vehicle, where it may be difficult for the driver of the host vehicle to determine whether or not there is another vehicle or object adjacent to the host vehicle.
