DRIVING ASSISTANCE SYSTEM FOR VEHICLE

摘要

An object of the invention is to provide a technology that can provide driving assistance matching the sense of the driver in a system for assisting avoidance of a collision of a vehicle. To achieve the object, a system for assisting avoidance of a collision of a vehicle according to the invention predicts a range of paths extending from a start point at the position at which the self-vehicle will arrive after free running for a predetermined period of time from the present time along which the self-vehicle can travel by possible driving operations that the driver can normally perform. The system does not perform driving assistance if a path along which a solid object can be avoided exists in the predicted range of paths, and performs driving assistance if a path along which a solid object can be avoided does not exist in the predicted range of paths.

主权项

1. A driving assistance system for a vehicle, comprising:
recognition means for recognizing a solid object existing in the surrounding of a self-vehicle; obtaining means for obtaining the momentum of the self-vehicle at the present time; and assistance means for obtaining, using the momentum obtained by said obtaining means as a parameter, an arrival point defined as a position at which the self-vehicle will arrive after free running for a predetermined period of time, obtaining a range of paths starting from said arrival point along which the self-vehicle can travel if changes in the momentum caused by possible driving operations that the driver can normally perform are added to the momentum obtained by said obtaining means, and performing driving assistance for avoiding a collision with the solid object recognized by said recognition means on condition that there is no avoidance line defined as a path along which a collision with said solid object can be avoided in said travel range.
