<p><P>PROBLEM TO BE SOLVED: To provide a vehicle including a collision preventing sensor capable of detecting an anterior vehicle or object without performing erroneous detection. <P>SOLUTION: A golf cart 10 includes a rear-end collision preventing sensor; and an obstacle sensor 33a, etc. The rear-end collision preventing sensor includes: a transmitter 31 for originating radio wave (a) to a posterior part; and a reception sensor 32 for receiving the radio wave (a) originated from the transmitter 31 of the golf cart 10a when a distance from the anterior golf cart 10a becomes equal to or less than a fixed distance. The obstacle sensor 33a, etc., originates ultrasonic wave (b) forward over a distance longer than the origination distance of the radio wave (a), and receives the ultrasonic wave (b) returned after collision against the object, to detect the anterior object. When the reception sensor 32 receives the radio wave (a), the golf cart 10 is stopped. When the reception sensor 32 does not receive the radio wave (a) and also the obstacle sensor 33a, etc., detects the object, the golf cart 10 is travelled at low speed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
