Abstract: An autonomous travel controller detects whether a host vehicle is carrying out a first course change for changing a course in a direction indicated by a turn indicator. Upon detecting that the host vehicle is carrying out the first course change, detecting whether there is a road that enables a second course change for changing the course of the host vehicle that branches from the road after the first course change. When a road that enables the second course change is detected, the autonomous travel controller turns the turn indicator off.

Abstract: Three links within one width-direction unit are included in respectively different link units. The links in the first row and the sixth row from the right end and the left end of a chain are included in the same link unit. The links in the second row and the fifth row are included in the same link unit. The links in the ninth row and the tenth row are included in the same link unit other than the link unit in which the links in the second row and the fifth row are included. With the above structure, the stress amplitude of the links forming a chain for a chain-type continuously variable transmission can be reduced.
