TURN SIGNAL DEVICE AND COLLISION AVOIDANCE SYSTEM

摘要

A turn signal device (20) comprising: a right-turn signal (21) and a left-turn signal (22) provided in a vehicle (11); an operation device (23) capable of generating operation signals; an acquisition unit (26) that obtains determination signals indicating determination results regarding the possibility of collision between the vehicle and a following vehicle (12); a normal operation control unit (27) that, on the basis of the operation signals, outputs normal operation control signals such that a plurality of light-emitting units for either or both the left-turn signal and the right-turn signal light up sequentially from the inside to the outside in the vehicle width direction; and a danger control unit (28) that outputs danger control signals such that, when a determination signal is obtained that indicates a determination result that there is a possibility of collision, the plurality of light-emitting units for both the left-turn signal and the right-turn signal light up sequentially from the outside to the inside in the vehicle width direction.
