Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
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 contact avoidance unit automatically performing a contact avoidance operation when said contact possibility judgement unit judges that there is a contact possibility of the subject vehicle with the oncoming vehicle; and an overtaking judgement unit for judging whether or not the subject vehicle is in course of overtaking a preceding vehicle, wherein when said overtaking judgement unit judges that the subject vehicle is in course of overtaking a preceding vehicle, said contact avoidance unit restrains the contact avoidance operation or ceases the contact avoidance operation being performed.
Claim 2
Dependent Claim
204 words
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 contact avoidance unit automatically performing a contact avoidance operation when said contact possibility judgement unit judges that there is a contact possibility of the subject vehicle with the oncoming vehicle; and an overtaking judgement unit for judging whether or not the subject vehicle is in course of overtaking a preceding vehicle, wherein when said overtaking judgement unit judges that the subject vehicle is in course of overtaking a preceding vehicle, said contact avoidance unit restrains the contact avoidance operation or ceases the contact avoidance operation being performed.
Claim 3
Dependent Claim
59 words
A safety running system for a vehicle according to claim 1 , wherein the contact avoidance operation performed by said contact avoidance unit is performed so that a steering device of the subject vehicle is steered in a direction opposite to a direction toward the oncoming vehicle which exists in a direction in which the subject vehicle is travelling.
Claim 4
Dependent Claim
77 words
A safety running system for a vehicle according to claim 1 , further comprising: a steered angle detection unit detecting a steered angle, wherein the overtaking judgement unit judges the initiation of overtaking of a preceding vehicle based on the relative vehicle velocity of the preceding vehicle detected by said object detection unit, the relative distance to the preceding vehicle detected by said object detection unit and the steered angle detected by said steered angle detection unit.
Claim 5
Dependent Claim
129 words
A safety running system for a vehicle according to claim 3 , further comprising: a vehicle velocity detection unit detecting the vehicle velocity of the subject vehicle; and a preceding vehicle velocity calculating unit calculating the vehicle velocity of the preceding vehicle based on the relative vehicle velocity of the preceding vehicle and the vehicle velocity of the subject vehicle detected by said vehicle velocity detection unit, wherein said overtaking judgement unit judges the completion of overtaking of the preceding vehicle based on a travel distance of the subject vehicle calculated from the vehicle velocity of the subject vehicle and a travel distance of the preceding vehicle calculated from the vehicle velocity of the preceding vehicle and the relative distance to the preceding vehicle when the overtaking is initiated.
Claim 6
Dependent Claim
38 words
A safety running system for the vehicle according to claim 2 , wherein the restraint of the contact avoidance operation by said contact avoidance unit is performed by a delay in timing when the steering device is operated.
Claim 7
Dependent Claim
38 words
A safety running system for a vehicle according to claim 2 , wherein the restraint of the contact avoidance operation by said contact avoidance unit is performed by reduction in amount in which the steering device is steered.
