Embodiment Construction

[0094] The following detailed description is merely exemplary in nature and is not intended to limit the invention or its application and uses.

[0095] figure 1 is a schematic diagram illustrating a host vehicle 100 and objects 102 in the vicinity of the host vehicle 100, according to an exemplary embodiment. Target 102 may be a vehicle, but target 102 may also represent other types of moving objects (eg, projectiles) or immovable objects.

[0096] Host vehicle 100 and target 102 are depicted in their current positions relative to each other. The host vehicle 100 travels along a host vehicle trajectory 104 on a curved surface having a turning center 108 and a turning radius 106 having a length or distance D1. Host vehicle 100 and target 102 are approaching each other. As used herein, "proximity" means that host vehicle 100 and target 102 are sufficiently proximate that a collision therebetween may occur. In one example, host vehicle 100 and target 102 may approach each ot...

Abstract

Methods and systems are provided for assessing a target proximate a vehicle. A location and a velocity of the target are obtained. The location and the velocity of the target are mapped onto a polar coordinate system via a processor. A likelihood that the vehicle and the target will collide is determined using the mapping.

Description

technical field [0001] The present invention relates generally to the field of vehicles, and more particularly to methods and systems for assessing objects of a crashable vehicle. Background technique [0002] Some vehicles today include systems for monitoring the movement of the vehicle relative to nearby vehicles and providing information about it to the driver of the vehicle. For example, some vehicles include systems that provide a determination of whether a nearby object (eg, another vehicle) is likely to collide with the vehicle on which the system is installed, and an estimated time of such a collision. However, such systems do not always provide this determination optimally, especially when the object is first detected, eg if the vehicle is driving on a curved surface. [0003] Accordingly, it would be desirable to provide an improved method for evaluating objects approaching a vehicle, such as estimating the probability of a collision between a host vehicle and an ...
