<p>PROBLEM TO BE SOLVED: To improve the reliability of a travelling body automatic locking device. SOLUTION: When a door on a driver's seat side is put in an open condition (S3: YES), a discrimination signal demand signal is sent (S6). Whether a discrimination signal sent from a portable machine is received or not (S7) and whether discrimination information corresponding to the received discrimination signal agrees with discrimination information of a vehicle itself or not (S8) are judged in a receiver. When the discrimination information agree each other, a flag is set (S9). When the flag is set, a door is locked even if the discrimination information agree each other at the time of closing. That is, the door is locked even if the discrimination information do not agree each other at the time of closing due to driver's throwing away the door to improve the reliability of a travelling body automatic locking device.</p> |
