  "textContent": "In a drive control method for using a drive control device to control the operation of a host vehicle using at least two autonomous driving modes that have different levels of driving assistance. The drive control method includes shifting the autonomous driving mode from a first mode to a second mode in which the driving assistance level of the second mode is higher than the driving assistance level of the first mode upon detecting a preceding vehicle in front of a host vehicle while traveling in the first mode. In this drive control method, a detectable distance to the preceding vehicle for shifting to the second mode is greater than a followable distance to the preceding vehicle when following travel is permitted in the first mode.",
