is input to a. The CPU 3a has a vehicle state input I / F1.
Based on the signal from 1, it is grasped that the driving operation has started and the driving operation has ended.

Therefore, the CPU 3a of the microcomputer 3 receives the ignition signal from the vehicle state input I / F 11 and the SAM.
The buzzer 5 is activated and sounds a buzzer sound (alarm) at the time of getting on (starting driving) and getting off (ending of driving) based on the loading detection signal of the ETC card 2 from the ETC card 4.
A caution is warned against unloading the C card 2 when the passenger boarded the vehicle and forgetting to remove the card 2 when getting off the vehicle.

(Riding) When the ETC card 2 is not loaded, an alarm is sounded. For example, the buzzer 5 sounds ten times every second. However, by pressing the buzzer stop key 6b, the CPU 3a of the microcomputer 3 controls the buzzer 5 to stop the buzzer sound (alarm). Thereby, when the driver feels the buzzer sound to be unpleasant while the buzzer 5 is sounding, the driver is released from the discomfort by pressing the buzzer stop key 6b.

When the ETC card 2 is inserted into the SAM 4 while the buzzer 5 is sounding and the card ID of the ETC card 2 is determined to be OK, the CP of the microcomputer 3 is
The U3a controls the buzzer 5 to immediately stop sounding based on the loading detection signal of the ETC card 2 from the SAM 4.

a controls the buzzer 5 to stop (step S
8).

Next, the CPU 3a sets the vehicle state input I /
Based on the ignition signal from F11, it is determined whether or not the ignition key 27 has been cut from the ACC position to the ON position (step S9). If the answer is no, the process returns to step S2. If the answer is yes, the process ends. Move on to other processing.

(When getting off) If the ETC card 2 is still loaded, an alarm is sounded. For example, the buzzer 5 is activated three times a second to distinguish it from the
Ring 3 times at 2 second intervals. If the ETC card 2 is removed during the sounding of the buzzer 5, the CPU 3a of the microcomputer 3 immediately stops the sounding of the buzzer 5 based on a detection signal from the SAM 4 indicating that the ETC card 2 has not been loaded. Control.

On the other hand, if the ETC card 2 has already been removed from the SAM 4 when getting off,
The PU 3a does not sound the buzzer 5 at all based on the detection signal from the SAM 4 indicating that the ETC card 2 has not been loaded.

Next, the operation at the time of getting off will be described with reference to the flowchart shown in FIG. First, when the driver gets off the vehicle 20 by turning the ignition key 27 from the ON position to the OFF position through the ACC position, the vehicle state input I / F 11 sends the CP of the microcomputer 3.

1).

Next, the CPU 3a monitors the loading detection signal from the SAM 4 and determines whether or not the ETC card 2 is inserted (step S12). If the answer is no (that is, if the ETC card 2 has already been removed), the CPU 3a ends this processing and moves to another processing.

On the other hand, if the answer to step S2 is YES (that is, if the ETC card 2 is still inserted), the CPU 3a controls the activation of the buzzer 5 and emits a buzzer sound (alarm) to one. 3 times per second, 3
Sounds continuously at intervals of 2 seconds (step S1).
3). Next, the CPU 3a determines whether or not the ETC card 2 is inserted (Step S14).

If the answer to step S14 is yes,
U3a determines whether the number of times of buzzer sound has reached three times at intervals of 2 seconds (step S15). If the answer is no, the process returns to step S13 to continue the buzzer sound.

On the other hand, if the answer to step S14 is no (that is, if the ETC card 2 is removed during ringing) or if the answer to step S15 is yes (that is, if the number of times the buzzer sounds is two seconds apart) If it has reached three times), the CPU 3a controls the buzzer 5 to stop (step S16). Thereafter, the CPU 3a ends the process.

In this manner, the driver can be notified that the ETC card has been forgotten to be inserted or removed when getting on or off the vehicle. Further, the sound can be stopped by operating the buzzer stop key 6b during the sound. Furthermore, the warning of forgetting to insert at the start of driving and the warning of forgetting to remove at the end of driving are issued in an identifiable manner, so that the driver is easy to understand.
