  FIG. 1 is a side view of an automobile 1 equipped with a sliding door, and shows a case where the sliding door 11 is in an open state. An actuator (for example, a motor) 111 for controlling unlocking / locking of the slide door 11 and a slide door side connector 112 are installed in the slide door 11.

  The body 12 of the automobile 1 is provided with a switch 121 that operates to unlock / lock the door of the automobile including the slide door 11, a control unit 122, and a body side connector 123 that fits with the slide door side connector 112. ing. FIG. 2 is a block diagram of a lock control device for a sliding door for automobiles according to the present invention. The sliding door side connector 112 and the body side connector 123 have at least four contacts, and the sliding door 11 is closed. When contacted, each contact is in electrical contact.

  That is, the sliding door side connector 112 is provided with four contacts 112a, 112b, 112c and 112d, and the actuator 111 is connected between the contacts 112a and 112b. Further, the wiring 112c is short-circuited between 112c and 112d. The body-side connector 123 is provided with four contacts 123a, 123b, 123c, and 123d that contact the contacts of the slide door-side connector 112, respectively.

  The contacts 123a, 123b and 123c are connected to the control unit 122, and the contact 123d is directly connected to a so-called Vcc power source. On the body 12 side, a door opening / closing switch 121 having an unlocking switch 121U and a locking switch 121L and an actuator 124 for controlling unlocking / locking of doors other than the slide door 11 are installed.

  FIG. 3 is a flowchart of a first lock control routine executed by the control unit. In step 31, it is determined whether the lock switch 121L of the door opening / closing switch 121 is turned on. If an affirmative determination is made in step 31, that is, if the lock switch 121 </ b> L is on, a lock signal for locking the door including the slide door 11 is output to the actuators 111 and 124.

  In step 33, the flag L indicating the locked state is set to "1", and in step 34, the voltage Vd of the contact 123c is read. If the sliding door 11 is in the open state, the contact 112c and the contact 123c are not in contact with each other, and the voltage Vd of the contact 123c is at the “L” level. On the contrary, if the sliding door 11 is in the closed state, the contact 112c and the contact 123c come into contact with each other, so that the voltage Vd of the contact 123c becomes “H” level.

  Therefore, the contacts 123c and 123d of the body side connector 123, the contacts 112c and 112d of the slide door side connector 112, and the wiring 113 constitute a sliding door open / close state identification means. In step 35, it is determined whether or not the voltage Vd of the contact 123c is at "H" level.

  If a negative determination is made in step 35, that is, if the slide door 11 is in an open state, the process returns to step 34. Conversely, if an affirmative determination is made in step 35, that is, if the slide door 11 is in the closed state, the process proceeds to step 36 to determine whether the flag L is “1”. If an affirmative determination is made in step 36, that is, once the door locking signal is output, the routine proceeds to step 37, where the locking signal is output again.

  Then, the process proceeds to step 38, the flag L is reset, and the process returns to step 34. When a negative determination is made at step 31 or step 36, this routine is directly terminated. Note that step 32 may be omitted in this routine, and the locking signal may be output to all the doors including the sliding doors after the sliding doors are closed.

  However, according to the above embodiment, if the sliding door is closed after the locking switch is turned on, the sliding door is immediately locked, so that the risk of closing the key cannot be avoided. FIG. 4 is a flowchart of a second lock control routine executed by the control unit in order to solve the above problem, and step 41 is added to the first lock control routine.

  When a negative determination is made in step 35, that is, when the lock switch is turned on and the slide door 11 is in the open state, the process proceeds to step 41 to output an alarm (for example, sounding an alarm sound or lighting an indicator lamp). . Therefore, it is possible to warn the driver that the door is locked when the sliding door is closed.

  FIG. 5 is a flowchart of a third lock control routine executed by the control unit in order to solve the above problem, and step 51 is added to the first lock control routine. When an affirmative determination is made in step 36, that is, when the locking switch is turned on and the slide door 11 is closed, the routine proceeds to step 51 where it is determined whether a predetermined time td has elapsed.

  And after predetermined time td passes, it progresses to step 37 and outputs a locking signal again. Therefore, since the locking signal is output again after a predetermined time (for example, 30 seconds) has elapsed after the slide door is closed, it is possible to suppress the possibility of the key being closed. In the above embodiment, the control unit 122 is used to electronically control the lock. However, a similar function can be mechanically executed.
