However, it is possible to set an appropriate time in each of these conditions.

  The smart card key system to which the vehicle remote control device according to this embodiment is applied is basically configured as described above. Next, the flowchart shown in FIG. A first embodiment of the battery rising prevention operation at the ACC position will be described with reference to FIG.

[First embodiment]
When the engine is operating, that is, when the knob 15 of the knob type ignition switch 56 is in the ON position, in step S1, when the switch from the ON position of the knob type ignition switch 56 to the ACC position due to the rotation of the knob 15 is detected. In S2, the time measurement of the second timer 92 for 1 hour, which is the second predetermined time, is started.

  Next, in step S3, it is detected whether or not the knob 15 is held at the ACC position. If the knob 15 is held at the ACC position, it is determined in step S4 whether or not the time measurement by the second timer 92 has ended. Is done.

  If the knob 15 is rotated from the ACC position to another position in step S3 while the process of step S3: YES → step S4: NO is repeated (step S3: NO), the process returns to step S1.

  On the other hand, during the repetition of the process of step S3: YES → step S4: NO, when the time measurement for one hour by the second timer 92 is completed (step S4: YES), “in-vehicle portable device exists” in steps S5 and S6. Confirmation process ”is performed.

  In this case, first, in step S5, the transmission request signal Sr is transmitted from the LF transmission antenna 44 in the vehicle.

  In step S6, if the portable device 18 is present in the passenger compartment, the transmission request signal Sr is received by the LF receiving circuit 106 through the reception antenna 108 of the portable device 18, and the CPU 100 of the portable device 18 wakes up. The ID code stored in its own ROM is read, and a response signal Sa including this ID code is transmitted through the RF transmission circuit 102 and the RF transmission antenna 104.

  When the response signal Sa including the ID code is received by the RF receiving circuit 42 through the in-vehicle RF receiving antenna 40, it is determined whether or not the received ID code matches the ID code stored in the ROM of the CPU 80. If so, it is determined that the authentication has been achieved, and the determination in step S6 is established. That is, the CPU 80 determines that the regular portable device 18 is in the passenger compartment. In this case, the CPU 80 returns to step S2, resets the second timer 92, and again counts the set time of the second timer 92. To start.

  On the other hand, if the response signal Sa including the ID code cannot be received in step S6, it is determined that the portable device 18 is taken out of the passenger compartment and the vehicle is left at the ACC position.

  When it is determined that the vehicle is left at the ACC position, the relay 60 is switched from the electricity supply position to the cutoff position in step S7.

  Therefore, after this switching time, the knob 15 of the knob type ignition switch 56 is in the ACC position. However, the CPU 80 forcibly switches the relay 60 from the power supply position to the shut-off position, thereby supplying the power from the battery 86 via the power supply line 88. The power supply to the accessory device 46 is stopped.

  As described above, according to the first embodiment described above, the accessory device 46 to which electricity is supplied from the battery 86 at the ACC position of the knob type ignition switch 56 is inserted between the battery 86 and the accessory device 46. A relay 60 as a power supply state switching means that can be switched between an electricity supply position and a cut-off position, a CPU 80 as a switch detection means for detecting switching from the ON position of the knob type ignition switch 56 to the ACC position, and a knob type ignition switch After the switch from the ON position of 56 to the ACC position is detected, the knob type ignition switch 56 has a second timer 92 that measures the time during which the knob-type ignition switch 56 is held at the ACC position.

  Then, the CPU 80 serving as the control means, after detecting the switch from the ON position of the knob type ignition switch 56 to the ACC position, has passed one hour which is a predetermined time held at the ACC position by the second timer 92. In step S5 when the signal is detected, the transmission request signal Sr is transmitted through the LF transmission circuit 54 and the LF transmission antenna 44, which are vehicle-side transmission means, into the vehicle interior, and the response signal Sa from the portable device 18 is transmitted by the vehicle-side reception means. When the signal is not received by a certain RF receiving antenna 40, the relay 60 is switched from the position for supplying electricity to the accessory device 46 to the blocking position.

  As described above, according to the first embodiment, in the smart card key system, the presence or absence of leaving the vehicle at the ACC position of the user of the portable device 18 is determined by communication with the portable device 18, and the vehicle is left at the ACC position. If it is determined that the supply of electricity to the accessory device 46 is forcibly and automatically interrupted, the battery 86 caused by leaving the vehicle while the accessory device 46 is operating at the ACC position is used. The rise can be prevented.

[Second Embodiment]
Next, a second embodiment of the battery running prevention operation at the ACC position will be described with reference to the flowchart shown in FIG.

  In the flowchart of FIG. 5, a specific getting-off detection process of steps S11 to S13 is added between step S1 and step S2 of the flowchart of FIG. 4. In the description of the flowchart of FIG. 5, description of the same contents as those of the flowchart of FIG. 4 is omitted.

  While the engine is operating, when it is detected in step S1 that the knob type ignition switch 56 is switched from the ON position to the ACC position due to the rotation of the knob 15, the door opening / closing detection switch 28 closes the door from the open state in step S11. It is detected whether there has been a transition to a state. Here, the reason why the transition from the open state to the closed state of the door is detected is to estimate whether or not the person carrying the portable device 18 gets off.

  In step S11, if the transition from the open state to the closed state of the door is not detected, the knob type ignition switch 56 is in the ACC position, so that the relay 60 is maintained in the state of being switched to the electricity supply position, and the accessory device 46 The power supply from the battery 86 through the power supply line 88 is continued.

  In step S11, if the door opening / closing detection switch 28 detects that the door has changed from the open state to the closed state, the driver who is the portable device 18 is likely to have got off the vehicle. The “in-vehicle portable device presence confirmation process”, which is the same process as steps S5 and S6, is performed in steps S12 and S13.

  Then, when the presence of the regular portable device 18 is not detected in step S13, it is determined that the passenger of the portable device 18 gets off, and the time measurement of the second timer 92 is started in step S2. Thereafter, the processing operations in steps S3 to S7 are the same as those in the first embodiment. However, when the determination in step S6 is established, the carrier of the portable device 18 that has once got off the vehicle has entered the vehicle interior again. And control is performed again from the door opening / closing detection process in step S11.

  According to the second embodiment, the getting-off detecting means (steps S11 to S13) for detecting the getting-off of the user of the portable device 18 is provided, and the second timer 92 is provided when the getting-off is detected by the getting-off detecting means. The predetermined time during which the knob 15 of the knob type ignition switch 56 is held at the ACC position is counted. For this reason, even if the user of the portable device 18 gets off at the ACC position and the vehicle is left at the ACC position for a long time while the accessory device 46 is operating, the battery 86 can be prevented from rising. In other words, in the smart card key system, it is possible to prevent the battery 86 from rising due to leaving the vehicle at the ACC position when the portable person 18 gets off the vehicle.

[Third embodiment]
Next, a third embodiment of the battery running prevention operation at the ACC position will be described with reference to the flowchart shown in FIG.

  In the flowchart of FIG. 6, “temporarily neglected detection processing at the ACC position” of steps S21 to S24 is added between step S1 and step S2 in the flowchart of FIG. In the description of the flowchart of FIG. 6, description of the same contents as those of the flowchart of FIG. 4 is omitted.

  During operation of the engine, when it is detected in step S1 that the knob type ignition switch 56 is switched from the ON position to the ACC position due to the rotation of the knob 15, the set time is 1 hour (second predetermined time) in step S21. The time measurement by the first timer 91 is started, which is shorter than the second timer 92 by 10 minutes (first set time).

  When it is detected in step S22 that the first timer 91 has finished measuring the set time, the “in-vehicle portable device presence confirmation process”, which is the same process as steps S5 and S6 described above, is performed in steps S23 and S24. When the presence of the portable device 18 in the vehicle interior is confirmed in step S24, it is determined that the accessory device 46 is in use, and in step S21, the time measurement of the set time by the first timer 91 is started again.

  On the other hand, when the presence of the regular portable device 18 is not detected in step S24, it is determined that the mobile phone 18 is left at the ACC position, and in step S2, the time measurement of the second timer 92 is started. Henceforth, the processing operation of step S3-S7 is the same as 1st Example.

  According to the third embodiment, after the switch of the knob type ignition switch 56 by the knob 15 from the ON position to the ACC position is detected, the knob type ignition switch 56 is held at the ACC position for a first predetermined time ( The first timer 91 that counts 10 minutes in this case, and the knob type ignition switch 56 that is longer than the first predetermined time after the first predetermined time is counted by the first timer 91 is held at the ACC position. And a second timer 92 that counts a second predetermined time (here, 1 hour), and the CPU 80 detects the passage of the first predetermined time by the first timer 91 and transmits a transmission request signal Sr into the vehicle interior. When the response signal Sa from the portable device 18 is received by the RF receiving antenna 40 and the RF receiving circuit 42, the first predetermined time by the first timer 91 is re-timed. In addition, when the response signal Sa from the portable device 18 is not received by the RF receiving antenna 40 and the RF receiving circuit 42, the second timer 92 starts counting and the second timer 92 causes the second predetermined time to elapse. If the response signal Sa from the portable device 18 is not received by the RF receiving antenna 40 and the RF receiving circuit 42 when the transmission request signal Sr is transmitted to the vehicle interior, the relay 60 is connected to the accessory device 46. Switch from the supply position to the shut-off position.

  That is, according to the third embodiment, when the knob type ignition switch 56 is switched from the ON position to the ACC position, the vehicle interior is detected when the first predetermined time (10 minutes) shorter than the second predetermined time (1 hour) elapses. When the transmission request signal Sr is transmitted and the response signal Sa is received, the user of the portable device 18 determines that the accessory device 46 is being used in the vehicle interior, so the portable device within the first predetermined time is used. For example, when the 18 passengers get off the vehicle, it is not determined that the vehicle is left at the ACC position.

  As shown in the modification of FIG. 7, the process of the third embodiment is performed after the start of time measurement by the second timer 92 in step S2 (the process of step S2 of FIG. 7 is the same as the process of step S2 of FIG. ), Step S4 (the process of step S4 in FIG. 7 is the same as the process of step S4 in FIG. 4), before the end of the time measurement of the second timer 92 in step S21 to S24 “ACC position”. If the response signal Sa is detected in step S24 after the time measurement by the first timer 91 is completed, the second timer 92 is counted again from the beginning in step S2. The same effect can be achieved by making such changes.

  Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted based on the contents described in this specification.
