Abstract
A turn signal device comprising: a right-turn signal and a left-turn signal provided in a host vehicle; an operation device for generating operation signals; an acquisition unit that acquires determination signals indicating determination results regarding the risk of a collision between the host vehicle and a following vehicle; a normal situation control unit that, based on the operation signals, outputs normal situation control signals such that light-emitting units for either or both the left-turn signal and the right-turn signal light up sequentially from an inner side to an outer side in the vehicle width direction; and a dangerous situation control unit that outputs dangerous situation control signals such that, when a determination signal indicates a determination result that there is a risk of collision, the light-emitting units for both the left-turn signal and the right-turn signal light up sequentially from the outer side to the inner side.
