<p>PROBLEM TO BE SOLVED: To prevent an estimated driving by reporting the existence of a curving car from a straight advancing car, which receives a report executing signal, to the driver of the straight advancing car by transmitting the signal when there is a report to the driver of the curving car. SOLUTION: When a driver tries to turn to the right and a right winker switch 5 is turned on, a search signal is transmitted by judging the start of right turn preparation. When the search signal is transmitted, it is judged whether a response signal is received or not and a distance judging circuit 4 judges the distance between a detection side vehicle A and a vehicle B on the side to be detected from a time difference between the search signal and the response signal. When there is the response signal and the distance to the straight advancing car B on a counter lane is to be concerned as a result of distance discrimination, reporting is executed by a display device 7. When there is the report executing signal within a prescribed time, this time, the reporting to the driver of the straight advancing car B is executed by a display device 14. From this report, the driver of the straight advancing car B can sense the existence of the right turning car B to be noticed on the front side of the counter lane.</p> |
