At 1, it is determined whether or not the re-lock timer for measuring the elapsed time after receiving the unlock signal is ON, that is, whether or not 1 is set to the timer flag Fa. The initial value of the timer flag Fa is set to 0 (zero), and after the re-lock timer for measuring the elapsed time after receiving the unlock signal is turned on, the timer flag Fa is set to 1 during the operation of the timer. Is set, and 0 (zero) when the timer is turned off
Is a flag returned to. If the result of the determination in step # 1 is NO, it is determined in step # 2 whether or not an unlock signal has been received. If the result is YES, the control signal is sent to the door lock motor drive unit 9. The output is output to drive each door lock motor M to the unlock side (step # 3), and at the same time, the timer is turned on and the timer flag Fa is set to 1 (step # 4). Next, in step # 5, it is determined whether or not the door switch S has been turned on, that is, whether or not the door has been actually opened. If this is YES, the timer is turned off in step # 10. (Timer flag Fa = 0).

On the other hand, if the result of the determination in step # 5 is NO
, That is, if the door has not been opened,
At step # 6, it is determined whether or not an unlock signal has been received. If YES, the relock timer is reset (step # 11), and after the measurement time t is returned to 0 (zero). Then, the measurement is started again. If the result of the determination in step # 6 is NO, it is determined in step # 7 whether or not a predetermined time Ta (for example, 30 seconds) has elapsed. If this is YES, The re-lock timer is turned off (step # 8), and at the same time, a control signal is output to the door lock motor driving section 9, and the door lock motor M is driven to the lock side.

Therefore, if the door is not opened even if the predetermined time Ta has elapsed after the last unlock operation of the door is performed, no unlock signal is received within this predetermined time. As long as the door is automatically relocked, as indicated by the dashed line in the graph of FIG. If a lock signal is received during execution of each step according to the above flow, the door lock motor M is driven to the lock side at that time, and the re-lock timer is turned off.

The timer flag Fb has an initial value set to 0 (zero), and after the transmission timer for measuring the elapsed time after the transmission of the unlock signal is turned on, 1 is set during the operation of the timer. This flag is set and returned to 0 (zero) when the timer is turned off. If the decision result in the above step # 21 is NO, it is determined in step # 22 whether or not the unlock switch is turned on. If this is YES, the transmitting unit 3 transmits an unlock signal. (Step # 2
At the same time as 3), the transmission timer is turned on, and the timer flag Fb is set to 1 (step # 24).

Next, in step # 25, it is determined whether or not a fixed time Tb (Tb <Ta), which is slightly shorter than a predetermined time Ta set in advance, has elapsed. Then, the transmission timer is turned off (timer flag Fb = 0), and the number N of times this transmission timer is turned off after being once turned on is increased by one (step # 27). Then, in step # 28, it is determined whether or not the count number N has reached a preset number. If this is NO, the unlock signal is automatically transmitted in step # 29. It has become.

Therefore, when the door is finally unlocked, an unlock signal is transmitted at a fixed time interval Tb slightly shorter than the predetermined time Ta when the door is re-locked by the automatic re-lock function. As long as the occupant carrying the transmitter 2 stays within the transmission / reception range, the unlock signal is received before the automatic re-lock function is activated, and as shown by the solid line in the graph of FIG.
