Travel control method and travel control apparatus
First Claim
1. A travel control method comprising:
- recognizing a lane line of a traffic lane in which a host vehicle is traveling;
performing lane keeping control such that a lateral position of the host vehicle is at a predetermined position with respect to the lane line;
detecting a preceding vehicle traveling ahead of the host vehicle in the traffic lane during the lane keeping control; and
when the lane line is not detected, canceling the lane keeping control when a predetermined time has passed after the lane line is no longer detected, whereinthe predetermined time is shorter when a following distance between the host vehicle and the preceding vehicle is longer than a predetermined value than when the following distance is shorter than or equal to the predetermined value.

Abstract
A travel control apparatus includes: a recognition processing section that recognizes a lane line of a traffic lane in which a host vehicle is traveling; a vehicle control section that performs lane keeping control such that a lateral position of the host vehicle is at a predetermined position with respect to the lane line; a radar that detects a preceding vehicle traveling ahead of the host vehicle; and a cancelling section that, when the recognition processing section does not detect the lane line, cancels the lane keeping control when a predetermined time has passed after the lane line is no longer detected. The predetermined time is shorter when a following distance between the host vehicle and the preceding vehicle is longer than a predetermined value than when the following distance is shorter than or equal to the predetermined value.

3. A travel control apparatus comprising:
-
a recognition processing circuit that recognizes a lane line of a traffic lane in which a host vehicle is traveling; a vehicle control circuit that performs lane keeping control such that a lateral position of the host vehicle is at a predetermined position with respect to the lane line; a sensor that detects a preceding vehicle traveling ahead of the host vehicle in the traffic lane; and a cancelling circuit that, when the recognition processing circuit does not detect the lane line while the sensor detects the preceding vehicle during the lane keeping control, cancels the lane keeping control when a predetermined time has passed after the lane line is no longer detected, wherein the predetermined time is shorter when a following distance between the host vehicle and the preceding vehicle is longer than a predetermined value than when the following distance is shorter than or equal to the predetermined value.
