<p><P>PROBLEM TO BE SOLVED: To provide a collision preventive system capable of quickly detecting an obstacle even if the travelling course of a golf cart 40 becomes flat from uphill or becomes flat from downhill. <P>SOLUTION: The inclination angle (θ) of the travelling course of the golf cart 40 is measured by an inclination sensor 18. When the travelling course is determined as uphill, the angle of an obstacle detecting sensor 36 is controlled to turn downward relative to the travelling direction. When the travelling course is determined as downhill, the angle of the obstacle detecting sensor 36 is controlled to turn upward relative to the travelling direction. The angle of the obstacle detecting sensor 36 is further controlled corresponding to the inclination angle (θ) of the travelling course and controlled to turn at the angle smaller than the inclination angle (θ). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
