Abstract

A method for controlling the motion of a mobile warning triangle for placement behind a stationary vehicle on a roadway acquires color information of the lane markings detected by a first sensor, a second sensor, and a third sensor of the mobile warning triangle. When the mobile warning triangle is placed on the roadway, the first to third sensors are preset in position to detect the lane markings and their colors. The white or yellow color information of the lane markings or of the black-colored roadway are detected or not detected on an individual basis by the sensors and deviations from a required path are recognized when different colors are received in certain combinations by the sensors. If no deviation is recognized in the colors, the mobile warning triangle is controlled to continue moving forward.
