(Shown in FIG. 1). The immobilizer code amplifier 18 is connected to an immobilizer electronic control unit (hereinafter, referred to as immobilizer ECU) 10 and receives the immobilizer code transmitted from the transmitter 11 via the antenna coil 17. The immobilizer code amplifier 18 inputs the received immobilizer code to the immobilizer ECU 10 as a digital signal.

The immobilizer ECU 10 stores an immobilizer code in advance. The immobilizer ECU 10 compares the input immobilizer code with a preset immobilizer code. The immobilizer ECU 10 operates the fuel injection device 13 based on the determination result. Also, Immobil EC
U10 operates the magnetic flux generation circuit 21 based on the detection result by the ignition switch 15. The magnetic flux generating circuit 21 is connected to the antenna coil 17, generates a magnetic flux in the antenna coil 17, and changes the generated magnetic flux.

The immobilizer ECU 10 constitutes a detecting means and a backup request outputting means. The antenna coil 17, the immobilizer code amplifier 18, the immobilizer E
The CU 10 and the magnetic flux generation circuit 21 constitute a second immobilizer system.

The keyless code amplifier 19 is connected to a door lock electronic control unit (hereinafter, referred to as a door lock ECU) 16 and receives a keyless code via an antenna 20. In addition, the keyless amplifier 19 converts the received keyless code into a digital signal as the door lock ECU 1.
Enter 6

The door lock ECU 16 stores a keyless code in advance. Door lock ECU1
Reference numeral 6 compares the input keyless code with a preset keyless code. The door lock ECU 16 operates the actuator 14 based on the determination result.

The door lock ECU 16 and the immobilizer E
The CU10 is connected by a signal line,
10, a backup request signal can be input. Further, when there is an input of the backup request signal and other conditions described later, the fuel injection device 13 is operated. The door lock ECU 16
Constitutes control means.

The antenna 20, the keyless cord amplifier 19, and the door lock ECU 16 constitute a second keyless system. As shown in FIGS. 1 and 2, the transmitter 11 includes a transponder 22 and a keyless transmitter 23 as a keyless transmitter.

The transponder 22 includes a power receiving coil 24, a power storage unit 25 including a capacitor and the like, and a power storage circuit 26.
And a transponder IC 27. The power receiving coil 24 faces the antenna coil 17 in a state where the ignition key 1 is inserted into the key cylinder 4, and generates an electromotive force by a mutual electromagnetic induction between the antenna coil 17 and the antenna coil 17. Power storage circuit 26 stores the electromotive force generated in power receiving coil 24 in power storage unit 25. The transponder IC 27 stores an immobilizer code in advance. And
When power of a predetermined voltage or more is stored in the power storage unit 25, the transponder IC 27 transmits an immobilizer code via the power receiving coil 24 using the power (indicated by a dotted line).

The transponder 22, the antenna coil 17, the immobilizer code amplifier 18, the immobilizer ECU 1
0 and the magnetic flux generating circuit 21 constitute a first immobilizer system.

The keyless transmission unit 23 includes a signal generation circuit 28, an output circuit 29, an antenna 30 also serving as a key plate, a switch 31, a power receiving coil 32, a power storage unit 33, and a power storage circuit 34. Similarly to the power receiving coil 24 of the transponder 22, the power receiving coil 32 faces the antenna coil 17 with the ignition key 1 inserted in the key cylinder 4, and the power receiving coil 32
7 generate an electromotive force by mutual electromagnetic induction.
The power storage circuit 34 stores the electromotive force generated in the power receiving coil 32 in the power storage unit 33. Then, when the switch 31 is pushed, the signal generation circuit 28 generates a keyless code using the electric power stored in the power storage unit 33. The output circuit 29 amplifies the generated keyless code and transmits it via the antenna 30.

The keyless transmitter 23, the antenna 20, the keyless cord amplifier 19, the door lock ECU
16 constitutes a first keyless system. Next, the operation of the present embodiment will be described.

FIG. 4 shows a flowchart executed by the door lock ECU 16. The operation of the keyless system will be described with reference to this flowchart. For example, the door lock mechanism 3 of the vehicle is in a locked state, and the driver attempts to get into the vehicle. Here, when the switch 31 of the transmitter 11 is pushed, a keyless code is transmitted. The keyless code transmitted from the transmitter 11 is received by the receiver 12. Upon receiving this, the door lock ECU 16 proceeds to step 100 (hereinafter, referred to as step 100).
In step S), the determination flag F is set to "0".
Reset to. Next, the door lock ECU 1 of the receiver 12
6 compares the received keyless code with a previously stored keyless code (S110). Then, when the keyless code is matched, the door lock ECU 16
The actuator 14 is operated to unlock the door lock mechanism 3 in the locked state (S120). Thus, without using the key (generally, the door lock mechanism 3
The ignition key 1 is used for unlocking / locking the door) and the door lock mechanism 3 can be unlocked.

Thereafter, in S130, the determination flag F
Is set to "1", and in S140, it is determined whether or not a backup request signal has been input within a predetermined time after the keyless codes match. If there is no backup request signal, the determination in S140 is “NO”. This processing routine ends.

Normally, when a regular user gets on board,
The processes of S100 to S130 are executed, and the flowchart ends. The processing of S140 to S170 will be described later.

Next, FIG. 3 shows a flowchart executed by the immobilizer ECU 10. The operation of the immobilizer system will be described below. As described above, the occupant gets on the vehicle, inserts the ignition key 1 into the key cylinder 4, and attempts to start the engine 2 by an engine starter (not shown) by the turning operation. When the ignition switch is detected by the ignition switch 15 (S10), the immobilizer ECU 10 performs a self-diagnosis,
It is determined whether various circuits controlled by the immobilizer ECU 10 are normal (S20). This step S20 constitutes a detecting means. If normal, the process proceeds to S30, and if abnormal, in S60, a warning lamp provided on an instrument panel (not shown) indicating that the immobilizer system is abnormal is turned on, and a backup request signal is output to the door lock ECU 16, The process of this flowchart ends. Said S
Reference numeral 60 constitutes backup request means.

If it is determined to be normal, the immobilizer ECU
10 operates the magnetic flux generation circuit 21. Therefore, a magnetic flux is generated in the antenna coil 17 and the generated magnetic flux is changed.

Here, the power receiving coil 24 of the transponder 22 is opposed to the antenna coil 17 mounted on the key cylinder 4 by inserting the ignition key 1 into the key cylinder 4 described above. Therefore, an electromotive force is generated in the power receiving coil 24 by the mutual electromagnetic induction between the power receiving coil 24 and the antenna coil 17 described above. The electromotive force generated in the power receiving coil 24 is stored in the power storage unit 25 by the power storage circuit 26. When the stored voltage of the power storage unit 25 becomes a predetermined value or more, the transponder IC 27
The immobilizer code is transmitted for a predetermined time via the control unit 4.

The receiver 12 receives the immobilizer code transmitted from the transmitter 11. The control circuit 16 of the receiver 12 compares the received immobilizer code with a preset immobilizer code (S30).

Here, if the immobilized codes match,
The start of the engine 2 is allowed by the immobilizer ECU 10,
The engine 2 is started based on the turning operation of the ignition key 1 described above (S40). If the immobilization codes do not match, the operation of the fuel injection device 13 is cut off by the immobilization ECU 10, and the engine 2 cannot be started (S50), and this flowchart ends. As a result, theft can be prevented.

Naturally, the engine cannot be started even when the immobilizer code is not input (direct ignition, etc.). The immobilizer ECU 10 continues the operation of the magnetic flux generation circuit 21 even after the start of the engine 2 is permitted. Therefore, the power storage unit 33 includes the ignition key 1
After the power supply is removed from the key cylinder 4, sufficient electric power for operating the keyless transmission unit 23 is stored.

The locking operation when the driver gets out of the vehicle can be performed by pushing the switch 31 in the same manner as the unlocking operation. That is, the door lock ECU 16 knows whether the door lock mechanism 3 is unlocked or locked. When the keyless code is received, the unlocking operation is performed on the door lock mechanism 3 in the unlocked state, and the unlocking operation is performed on the door lock mechanism 3 in the locked state. The actuator 14 is operated to perform the operation.

Now, returning to the flowchart of FIG.
When a backup request signal is input from the immobilizer ECU 10 to the door lock ECU 16 as described above, S
In 140, if a backup request signal is input within a predetermined time (for example, 10 minutes) after the keyless codes match, the determination in S140 is “YES”. Then, in step 150, it is determined whether or not the determination flag F is set to “1”. The determination flag F is for determining whether or not the door has been unlocked using a keyless system to get on the vehicle. Therefore, when the discrimination flag F is set to "1", it means that the occupant is using the keyless system. If the determination flag F is reset to "0", it means that the occupant is riding without using the keyless system.

Therefore, if the determination flag F has been reset to "0", this determination is made "NO", and S17
Then, the operation of the fuel injection device 13 is cut by the door lock ECU 16 and the start of the engine 2 becomes impossible, and this flowchart ends. In other words, since the vehicle is boarded without using the keyless system, the engine is not started on the assumption that a person who is not a regular user of the vehicle is aboard. As a result, theft can be prevented.

If the determination flag F is set to "1", the determination is "YES", and the routine proceeds to S160, where the start of the engine 2 is permitted by the door lock ECU 16 and the above-described ignition key The engine 2 is started based on the rotation operation of the engine 1. Thereafter, the process exits from this processing routine.

The present embodiment having the above configuration has the following effects. (A) Even if the immobilizer system breaks down, the door lock system backs up, so that the engine can be started easily. Also, when the door lock system is backed up, backup is performed only when boarding using the door lock system, so if the door lock is destroyed and boarded, for example, start the engine. Can not. As a result, theft can be prevented even when the immobilizer system breaks down.

The power storage unit 33 stores power in the antenna coil 17 of the receiver 12. Therefore, a primary battery is not required as an operating power source for the keyless transmission unit 23, and troublesome battery replacement is not required even when the battery runs out.

(Second Embodiment) Next, a second embodiment will be described with reference to FIG. The description will be focused on the differences from the first embodiment.

FIG. 5 is a flowchart executed by the door lock ECU 16, in which S100 and S130 are omitted and S150A is processed instead of S150 in comparison with the flowchart of FIG. 4 of the first embodiment.

That is, in this embodiment, the flowchart of FIG. 3 is executed by the immobilizer ECU 10 as in the first embodiment. Then, in S20, Immobil EC
The U16 performs a self-diagnosis and determines whether or not various circuits controlled by the immobilizer ECU 16 are normal. Turn on the warning lamp. The passenger visually recognizes the warning lamp and pushes the switch 31 of the transmitter 11.

Then, the keyless code transmitted from the transmitter 11 is received by the receiver 12. This reception
If it is within a predetermined time (for example, two minutes) after the input of the backup request signal, the determination in S150A is “YES”, and the process proceeds to Step 160; otherwise, the process proceeds to S170. .

(D) In this embodiment, when the door lock is unlocked without using the door lock system and the immobilizer system breaks down, the transmitter 1
When the first switch 31 is turned on, the engine can be started.
