Collision Avoidance System
First Claim
1. A collision avoidance system comprising:
- an obstacle detection means for detecting obstacles existing in the vicinity of a host vehicle;
an action range presumption means for presuming an action range in which an obstacle can exist at time a predetermined time after being detected on the basis of the moving performance of the obstacle detected by the obstacle detection means;
an action probability presumption means for estimating an action probability of the obstacle existing in the action range presumed by the action range presumption means; and
a driving operation support means for determining driving operation support operations on the basis of the action range presumed by the action range presumption means and the action probability presumed by the action probability presumption means and executing the driving operation support operations.

Abstract
According to the present invention, an obstacle detection means detects an obstacle. An action range presumption unit presumes an action range in which the obstacle can exist in a predetermined time if the obstacle accelerates, decelerates, or turns on the basis of the moving performance of the obstacle detected by the obstacle detection means. An action probability presumption unit presumes a probability of the obstacle existing in the action range on the basis of the conditions of the road on which a host vehicle and the obstacle exist and the action history of the obstacle. A driving operation support unit determines a target locus which prevents the host vehicle from moving into the presumed action range or to a position where the action probability is high and generates vehicle control information necessary for making the host vehicle run along the target locus. The driving operation support unit gives the driver instructions and warnings and assists the driver with driving operation support operations. Thus, the possibility of collision of the host vehicle with the obstacle can be reduced even if the obstacle makes an action beyond the scope of the driver'"'"'s assumption.
