Steering assist system
First Claim
1. A steering assist system comprising:
- traffic-line detecting means for detecting right and left traffic lines marked on a road;
preceding-vehicle detecting means for detecting a preceding vehicle traveling ahead of a subject vehicle;
traveling-target-point setting means for setting a traveling target point for traveling of the subject vehicle at a predetermined position in the preceding vehicle when the preceding vehicle is not within predetermined ranges from the right and left traffic lines, and for setting the traveling target point at a position offset from the predetermined position in the preceding vehicle toward the center of a traveling lane of the subject vehicle when the preceding vehicle is within the predetermined range of any one of the right and left traffic lines; and
steering control means for controlling steering so that the subject vehicle passes over the traveling target point, whereinan offset amount of the traveling target point is calculated according to the following expression when the preceding vehicle is traveling near the right traffic line;

7. A steering assist system comprising:
-
traffic-line detecting means for detecting right and left traffic lines marked on a road; preceding-vehicle detecting means for detecting a preceding vehicle traveling ahead of a subject vehicle; traveling-target-point setting means for setting a traveling target point for traveling of the subject vehicle at a predetermined position in the preceding vehicle when the preceding vehicle is not within predetermined ranges from the right and left traffic lines, and for setting the traveling target point at a position offset from the predetermined position in the preceding vehicle toward the center of a traveling lane of the subject vehicle when the preceding vehicle is within the predetermined range of any one of the right and left traffic lines; and steering control means for controlling steering so that the subject vehicle passes over the traveling target point, and wherein an offset amount of the traveling target point is corrected so as to increase the absolute value of the offset amount when another vehicle is detected in a traveling lane adjacent to the traveling lane of the subject vehicle.

13. A steering assist system comprising:
-
traffic-line detecting means for detecting right and left traffic lines marked on a road; preceding-vehicle detecting means for detecting a preceding vehicle traveling ahead of a subject vehicle; traveling-target-point setting means for setting a traveling target point for traveling of the subject vehicle at a predetermined position in the preceding vehicle when the preceding vehicle is not within predetermined ranges from the right and left traffic lines, and for setting the traveling target point at a position offset from the predetermined position in the preceding vehicle toward the center of a traveling lane of the subject vehicle when the preceding vehicle is within the predetermined range of any one of the right and left traffic lines; and steering control means for controlling steering so that the subject vehicle passes over the traveling target point, wherein when a steering wheel is turned, the traveling-target-point setting means sets the traveling target point at a position offset in an input direction of steering torque input by the turn, and an offset amount of the traveling target point in the input direction of the steering torque is set so that the absolute value of the offset amount is more than a normal value when another vehicle is detected in a traveling lane adjacent to the traveling lane of the subject vehicle in a direction opposite the input direction of the steering torque.
