<p><P>PROBLEM TO BE SOLVED: To provide a drawing system which detects driver's vehicle operation information and informs movement start timing of its own vehicle to other vehicles. <P>SOLUTION: When detecting that the own vehicle is stopped at a crossing while waiting for a right-turn, a navigation ECU 3 draws a right-turn wait mark showing a right-turn waiting state on a road surface of opposite lane at the crossing where the own-vehicle stops by a visible laser beam in a predetermined color (S18-S20). When detecting that the own vehicle shifts to a right-turn start state from stop and right-turn waiting state at the crossing, the navigation ECU 3 draws a right-turn start mark showing a right-turn start state, in place of the right-turn wait mark in a color different from the color of the right-turn start mark (for example, red) in accordance with entering state of the own-vehicle and at almost the same location on the road surface of the opposite lane at the crossing into which the own-vehicle is entering with a visible laser beam (S21-S22). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
