Abstract:
PROBLEM TO BE SOLVED: To prevent or suppress a situation where a hazard lamp is automatically turned on unnecessarily on a bad road, without increasing a predetermined threshold value.SOLUTION: When a deceleration β of a vehicle 1 is turned to a predetermined threshold value G or more under the control by a controller 21, a hazard lamp 2 is automatically turned on. The deceleration β is calculated based on a vehicle speed detected by a vehicle speed sensor 22, for example. A calculation condition of a deceleration is changed so that a deceleration β when the vehicle travels on a bad road is suppressed from becoming larger than a deceleration β when the vehicle travels on a good road.
