  "textContent": "A lane disappearance region S, in which no lane that continues from a current lane can be recognized, is detected along an extension of the travel route of the host vehicle during lane-keeping travel in which \"hands-off mode M1\" has been selected. If the lane disappearance region S is detected, information on the lane disappearance start point Ps1 is acquired, and mode transition positions (the first position P1 and the second position P2) are set between the host vehicle position and the lane disappearance start point. If the host vehicle reaches a mode transition position, a mode transition from \"hands-off mode M1\" to a steering wheel grip mode (\"hands-on mode M2\" or \"steering wheel operation mode M3\") is requested. If gripping of the steering wheel 23 by the driver has been confirmed, a mode transition is performed from the steering wheel grip mode to \"steering wheel assist deactivation mode M4\" before the host vehicle reaches the lane disappearance start point Ps1.",
