<P>PROBLEM TO BE SOLVED: To make the right-turn determination device of a self-vehicle recognize a right-turn behavior according to a positional relation between the self-vehicle and another vehicle. <P>SOLUTION: Right-turn determination means (10) includes another vehicle information acquisition means (11) for acquiring the position, traveling azimuth and traveling speed of another vehicle. The right-turn determination means is configured to determine that the self-vehicle turns right when all the following conditions are established even when azimuth conditions are not established from the position and traveling azimuth of the self-vehicle detected by a GPS module (3) and the information acquired by the other vehicle information acquisition means (11). The above mentioned conditions are a first condition that the traveling speed of the other vehicle is equal to or less than a first speed on the basis of which it is determined that the vehicle is stopping, a second condition that the position of the other vehicle has changed from the back part of the self-vehicle to the front part of the self-vehicle, and a third condition that the position of the other vehicle has changed from the front part of the self-vehicle to the back part of the self-vehicle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
