Abstract

In a safety running system, a transverse travelling distance resulting when a subject vehicle travels to a current position of an oncoming vehicle is calculated based on the vehicle velocity and yaw rate of the subject vehicle, a relative transverse distance of the oncoming vehicle relative to a vehicle body axis of the subject vehicle is calculated based on a relative distance, relative velocity and relative angle between the subject vehicle and the oncoming vehicle detected by a radar information processor. When a relative transverse deviation obtained by subtracting the transverse travelling distance from the relative transverse distance resides within a range and that state continues to exist over a predetermined time period, it is judged that there is a collision possibility of the subject vehicle with the oncoming vehicle, and automatic steering is performed so as to avoid a collision.

Claims7

Dependent claims

A safety running system for a vehicle, comprising:

a detection unit detecting an object existing in a direction in which a subject vehicle travels;
a travelling locus estimation unit estimating a future travelling locus of the subject vehicle;
a relative transverse deviation calculation unit calculating a relative transverse deviation between the subject vehicle and an oncoming vehicle based on the results of the detection by said object detection unit and said future travelling locus of the subject vehicle;
a contact possibility judgement unit judging that there is a contact possibility of the subject vehicle with the oncoming vehicle when said relative transverse deviation calculated by said relative transverse deviation calculation unit is within a predetermined range;
a curve exit detection unit detecting that the subject vehicle approaches an exit portion of a curve;
and
a correction unit for correcting said relative transverse deviation based on the results of the detection by said curve exit detection unit.
