Vehicle environment monitoring system
First Claim
1. A vehicle environment monitoring system for monitoring an external environment proximate to a vehicle, and for detect an object existing in the external environment of said vehicle from an image obtained by imaging means mounted on said vehicle, the vehicle environment monitoring system comprising:
- vehicle speed detecting means for detecting a running speed of said vehicle;
distance calculating means for calculating a distance between said object and said vehicle based on the image obtained by said imaging means;
relative speed calculating means for calculating a relative speed between said object and said vehicle according to the distance calculated by said distance calculating means; and
probability determining means for determining whether or not there is a significant probability that said vehicle may collide with said object, based on the running speed of said vehicle and the distance calculated by said distance calculating means, on condition that the relative speed is in the vicinity of the running speed of said vehicle.

Abstract
A vehicle environment monitoring system for an automotive vehicle, is capable of accurately detecting the movement of an object existing in an external environment of the vehicle, and determining the probability of collision between the object and the vehicle, thereby appropriately warning the driver. A running speed of the vehicle is detected, and a distance between the object and the vehicle is calculated, based on the image obtained by the imaging device. A relative speed between the object and the vehicle is calculated according to the calculated distance. It is determined whether or not there is a significant probability that the vehicle may collide with the object, based on the running speed of the vehicle and the distance therebetween on condition that the relative speed is in the vicinity of the running speed of the vehicle.
