Description

The present invention relates to a remote start control device, and more particularly, to a remote start control device for mounting on a vehicle having an immobilizer function.

Recently, vehicles equipped with an anti-theft function called an immobilizer have been increasing. In order to realize the immobilizer function (for the engine), as shown in FIG. 5, an ignition key 1 storing a specific code and having a chip 3 having a transmitting function in a grip portion 2 and a key cylinder 4 And a transponder 5 attached to the key cylinder 4, an immobilizer unit 6 that stores a vehicle-specific code and has a function of preventing theft, and an engine control unit 7 that performs control such as starting the engine. I have.

When the ignition key 1 is inserted into the key cylinder 4 by the driver (or the ignition key 1 is turned to the ACC output position or the IG output position of the ignition switch), the key insertion detection signal is set to the high state, The immobilizer unit 6 receiving the signal transmits a start signal to the transponder 5 via the signal line L1.

When the transponder 5 receives the activation signal, the transponder 5 performs wireless communication with the chip 3 of the ignition key 1 inserted in the key cylinder 4, thereby acquiring the specific code stored in the chip 3, and acquiring the specific code. The specific code is transmitted along with the clock signal to the signal line L
2 to the immobilizer unit 6.

The immobilizer unit 6 determines whether the specific code sent from the transponder 5 matches a vehicle-specific code stored in advance, and if it determines that these codes match, the ignition key 1 is turned on. The driver inserted into the key cylinder 4 is regarded as a legitimate driver, and a permission signal for permitting the engine to start is given to the engine control unit 7.

When the engine control unit 7 receives a starter signal output from the key cylinder 4 after receiving the permission signal, the engine control unit 7 performs engine control such as fuel and ignition timing. When the starter signal is received without receiving the signal, the engine control is not performed.

As described above, unless the code stored in the chip 3 of the ignition key 1 is a code unique to the vehicle, the engine cannot be started. Therefore, if the ignition key or the ignition switch is incorrectly connected directly, the engine cannot be started, and vehicle theft can be prevented.

On the other hand, a remote start control device for starting an engine such as an engine by remote control has been put into practical use. As shown in FIG. 6, when the remote start control device 18 receives a signal for instructing engine start from the portable transmitter 19 carried by the driver, the remote start control device 18 controls the proper ignition key 1
An ACC signal, an IG signal, and a pseudo signal corresponding to the starter signal that are output when 1 is turned to the starter output position are supplied to the signal line L3 of the ignition switch, and these pseudo signals are transmitted to the engine control unit 17. It is supposed to.
Thus, the engine can be started only by transmitting a signal for instructing start of the engine from the portable transmitter 19 without inserting the ignition key 11 into the key cylinder 14 and rotating the key.

However, when the above-mentioned remote start control device 18 is additionally provided in a vehicle having the above-mentioned immobilizer function, the vehicle-specific code stored in the immobilizer unit 6 must be matched,
That is, since it is necessary to insert the regular ignition key 1 into the key cylinder 4, even if the pseudo signals (the pseudo signals of the ACC signal, the IG signal, and the starter signal) are given to the engine control unit 7, the engine is started. There is a problem that you can not do.

In order to solve such a problem, a vehicle-specific code is stored in a remote start control device, and when an engine start instruction is received by remote control, the vehicle-specific code is transmitted from the remote start control device to the immobilizer unit. To transmit the permission signal from the immobilizer unit to the engine control unit (see Patent Document 1 below).
).

However, in the conventional remote start control device, regardless of whether the permission signal is provided or not provided from the immobilizer unit to the engine control unit (that is, the permission signal is transmitted from the remote start control device to the immobilizer unit). (Regardless of whether the obtained code matches the code unique to the legitimate vehicle) and the pseudo signal (the pseudo signal of the ACC signal, the IG signal, and the starter signal) to the engine control unit 7 to start the engine. And had

Therefore, even though the permission signal is not given to the engine control unit 7 (that is, the start of the engine is not permitted), the process of starting the engine is wastefully performed. This may damage the starter motor of the engine, and also lowers the battery voltage, which may make it difficult to start the engine thereafter.

Means for solving the problem and its effects

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a remote start control device capable of protecting a starter motor and the like by eliminating a process of starting an engine such as a useless engine. .

In order to achieve the above object, a remote start control device (1) according to the present invention outputs a start signal based on a predetermined operation, captures a code output based on the start signal, and reads the captured code. It is determined whether or not the codes are unique to the vehicle. If these codes match, the engine or other engine is permitted to start.On the other hand, if it is determined that these codes do not match, the start signal is again applied. A remote control device mounted on a vehicle equipped with a start control device for outputting a start signal, and for remotely controlling the start of the engine, storing means for storing a code, and starting the engine by remote control When receiving the instruction signal, a pseudo signal corresponding to the predetermined operation is supplied to the start control device, so that the start control device outputs the start signal. Supply control means for receiving the start signal transmitted from the start control device based on the pseudo signal, and supplying the code stored in the storage means to the start control device. Means and start permission determining means for determining whether or not the start of the engine is permitted by the start control device after supplying the code stored in the storage means to the start control device. It is characterized by:

The code output based on the predetermined operation (for example, a specific code is stored, and an ignition key that incorporates a chip having a transmission function in a grip portion is inserted into a key cylinder, etc.) is, for example, If the ignition key is authentic, it matches the vehicle-specific code.

According to the remote start control device (1), when a start instruction signal for the engine (for example, an engine or the like) is received by remote control, a pseudo signal (for example, a key insertion detection signal corresponding to the key insertion detection signal) corresponding to the predetermined operation is received. Signal) is supplied to the start control device, and further, when a start signal transmitted from the start control device based on the pseudo signal is received, a code (for example, a vehicle-specific code) stored in the storage means is received. ) Is supplied to the start control device. Examples of the engine include a power generation device such as an engine of an internal combustion engine automobile and a motor of an electric automobile.

Therefore, even when an instruction to start the engine is given by remote control, the vehicle-specific code can be supplied to the start control device in the same manner as when a regular ignition key is inserted into a key cylinder, The start control device can give permission to start the engine. As a result, the engine or the like can be started by remote operation without inserting a proper ignition key into the key cylinder and rotating the key.

Further, according to the remote start control device (1), after the code stored in the storage means is supplied to the start control device, it is determined whether or not the start of the engine is permitted by the start control device. Is determined. Therefore, it is possible to determine whether or not to perform the process of starting the engine based on the result of this determination, so that when the starting of the engine is not permitted,
It is possible to prevent the processing from being performed.

Further, the remote start control device (2) according to the present invention starts the engine when the remote start control device (1) determines that the start of the engine is permitted by the start permission determining means. It is characterized by having a starting means for performing the processing.

According to the remote start control device (2), when the start of the engine is permitted, a process of starting the engine (for example, a starter signal output when an ignition key is turned to a starter output position) Is transmitted to the engine control unit. Therefore, it is possible to prevent the process of starting the engine from being uselessly performed even though the start of the engine is not permitted. As a result, protection of the starter motor can be achieved, and a decrease in battery voltage can be prevented.

Further, the remote start control device (3) according to the present invention includes the remote start control device (1) or (2).
)), After the second supply control means supplies the code stored in the storage means to the start control device, the start control device outputs the start signal. If not, it is determined that the start of the engine is permitted by the start control device.

The start control device outputs a start signal based on the predetermined operation, captures a code output based on the start signal, and determines whether the captured code is a vehicle-specific code, When it is determined that these codes match, the engine or other engine is permitted to start, and when it is determined that these codes do not match, the start signal is output again. That is, the start control device does not output the start signal when permitting start of an engine such as an engine.

In other words, when the start signal is output from the start control device after the code output based on the start signal is captured by the start control device, the start of the engine is not permitted. Conversely, if the start control device does not output the start signal, the start of the engine is permitted.

According to the remote start control device (3), when the start signal is not output from the start control device after the code stored in the storage means is supplied to the start control device (for example, (If the start signal is not output from the start control device within 2 seconds after the code is supplied to the start control device), it is determined that the start of the engine is permitted by the start control device. Thus, it is possible to accurately determine whether or not the start of the engine is permitted by the start control device without making the device complicated.

An embodiment of a remote start control device according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram schematically showing a main part of an engine starting system employing a remote start control device according to the embodiment (1). Here, the same components as those of the engine start system shown in FIG. 5 are denoted by the same reference numerals.

The engine start system includes an ignition key 1 that stores a vehicle-specific code and has a chip 3 having a transmitting function in a grip portion 2, a key cylinder 4, a transponder 5 attached to the key cylinder 4, It includes an immobilizer unit 6 that stores a vehicle-specific code and has a function of preventing theft, an engine control unit 7 that performs control such as engine start, a remote start control device 31, and a portable transmitter 37. It is composed of

The remote start control device 31 includes a microcomputer 32, an antenna 33 for receiving a signal transmitted from the portable transmitter 37, a receiving unit 34, and an EE in which a remote ID code is stored.
It comprises a PROM 35 and an EEPROM 36 for storing the vehicle-specific code. Further, the remote start control device 31 can take in an alternator drive signal used for determining whether or not the engine has started, and can control opening and closing of a switch 5a connected to the transponder 5. ing.

The portable transmitter 37 includes a microcomputer (not shown), an antenna 38 for transmitting a predetermined signal to the remote start control device 31, an EEPROM (not shown) storing a remote ID code, It is configured to include a button switch 39a for instructing start of the engine from a remote place and a button switch 39b for instructing stop of the engine.

When the button switch 39a is pressed, the microcomputer of the portable transmitter 37 transmits a signal including the remote ID code and the instruction code for starting the engine from the antenna 38 to the outside. When the button 39b is pressed, a signal including the remote ID code and the engine stop instruction code is transmitted from the antenna 38 to the outside.

When the ignition key 1 is inserted into the key cylinder 4 by the driver (or the ignition key 1 is turned to the ACC output position or the IG output position of the ignition switch), the key insertion detection signal is set to the high state, The immobilizer unit 6 having received the signal transmits a pulse-like activation signal to the transponder 5 via the signal line L1, and requests a code unique to the vehicle.

When the transponder 5 receives the activation signal, the transponder 5 performs wireless communication with the chip 3 of the ignition key 1 inserted in the key cylinder 4 to acquire a code stored in the chip 3, and clocks the acquired code to a clock. The signal is output to the immobilizer unit 6 via the signal line L2 together with the signal.

The immobilizer unit 6 determines whether or not the code sent from the transponder 5 matches a vehicle-specific code stored in advance, and the codes match (that is, the regular ignition key 1 If it is determined that the engine has been inserted into the key cylinder 4), a permission signal for permitting the engine to start is given to the engine control unit 7.

On the other hand, if the code transmitted from the transponder 5 does not match the code unique to the vehicle, the activation signal is transmitted to the transponder 5 again after a short time. This operation is repeated until both codes match (however,
There is an upper limit.)

When the engine control unit 7 receives a starter signal output from the key cylinder 4 after receiving the permission signal, the engine control unit 7 performs engine control such as fuel and ignition timing. When the starter signal is received without receiving the signal, the engine control is not performed.

As described above, unless the code stored in the chip 3 of the ignition key 1 is the same as the vehicle-specific code stored in the immobilizer unit 6, the engine cannot be started. Therefore, if the ignition key or the ignition switch is incorrectly connected directly, the engine cannot be started, and vehicle theft can be prevented. The remote start controller 31 is connected to the signal lines L1 to L3, and can transmit and receive various signals using the signal lines L1 to L3.

Next, the processing operation [1] -1 (main routine) performed by the microcomputer 32 in the remote start control device 31 according to the embodiment (1) will be described based on the flowchart shown in FIG. First, a flag, a counter, and the like are cleared by performing initialization (step S1), and then, it is determined whether a signal has been received via the antenna 33 and the receiving unit 34 (step S2). If it is determined that the signal has been received, it is determined whether or not the ID code included in the received signal matches the remote ID code stored in the EEPROM 35 (step S3).

If it is determined that the ID code included in the received signal matches the remote ID code (that is, the signal transmitted from the portable transmitter 37 carried by the authorized driver has been received), then, It is determined whether the signal includes an instruction code for starting the engine (step S4). If it is determined that the signal includes the instruction code for starting the engine, the process proceeds to step S5 to start the engine. Then, the process proceeds to step S8 to perform a program process described later, then proceeds to step S9 to perform other processes, and returns to step S2.

On the other hand, if it is determined that the signal does not include an engine start instruction code, then it is determined whether the signal includes an engine stop instruction code (step S6). If it is determined that the stop instruction code is included, the key insertion signal, ACC
The engine is stopped by turning off both the signal and the IG signal to stop the engine (step S7). If it is determined that the signal does not include any of the instruction codes for starting and stopping the engine, the process proceeds to step S8.

In step S2, it is determined that no signal has been received. In step S3, although a signal has been received, a signal transmitted from the portable transmitter 37 carried by the legitimate driver has been received. If it is determined that it is not the case, it is not necessary to perform processing such as engine start or engine stop, and the process proceeds directly to step S8.

Next, the processing operation [1] -1a (the engine start processing in step S5 in FIG. 2) performed by the microcomputer 32 in the remote start control device 31 according to the embodiment (1) will be described based on the flowchart shown in FIG. I do. Note that the processing operation [1] -1a is an operation performed when the portable transmitter 37 is operated and an instruction to start the engine is issued from a remote place.

First, the remote starting flag f ₁ to 1 (step S11), and then, the key insertion detecting signal ignition key 1 regular is output when it is rotated to the IG signal output position, ACC
The signal and the pseudo signal corresponding to the IG signal are supplied to the signal line L3 of the ignition switch, the pseudo signal is transmitted to the immobilizer unit 6, the immobilizer unit 6 is operated (step S12), and the switch 5a is closed. And cut off the power of transponder 5,
The operation of the transponder 5 is prohibited (step S13).

Next, it is determined whether or not the activation signal output from the activated immobilizer unit 6 has been received (
Step S14) If it is determined that the activation signal has not been received, the process returns to step S14 and waits for the transmission of the activation signal. On the other hand, if it is determined that the activation signal has been received, the counter c is set to 0 (step S15), and the code stored in the EEPROM 36 is transmitted to the immobilizer unit 6 via the signal line L2 (step S16). Thereafter, it is determined whether or not the activation signal has been received again from the immobilizer unit 6 within a predetermined period (for example, 2 seconds) (steps S17 and S18). The activation signal is originally transmitted to the transponder 5, but since the operation of the transponder 5 is prohibited, no particular problem occurs.

Upon receiving the code transmitted via the signal line L2, the immobilizer unit 6 determines whether the received code (that is, the code stored in the EEPROM 36) matches the vehicle-specific code registered in advance. If these codes match, a permission signal for permitting engine start is transmitted to the engine control unit 7 and the re-transmission of the start signal is not performed thereafter. I have. On the other hand, if it is determined that the received code does not match the code unique to the vehicle, retransmission of the activation signal is repeated.

Therefore, the fact that the activation signal is not received again within two seconds after the transmission of the code stored in the EEPROM 36 means that the code stored in the EEPROM 36 matches the code unique to the vehicle, and the immobilizer unit 6 This indicates that the permission signal has been transmitted to the control unit 7.

Conversely, re-receiving the activation signal within two seconds after the transmission of the code stored in the EEPROM 36 means that a code matching the vehicle-specific code is not registered in the EEPROM 36, or This indicates that the immobilizer unit 6 has determined that they do not match due to noise or the like (even if a code that matches the vehicle-specific code is registered).

In steps S17 and S18, the activation signal is not re-received from the immobilizer unit 6 within two seconds (that is, the code stored in the EEPROM 36 matches the vehicle-specific code, and the immobilizer unit 6 sends the engine control unit 7 If the permission signal has been transmitted), the switch 5a is opened to release the power cut of the transponder 5 (step S19).

Next, a pseudo signal corresponding to a starter signal output when the ignition key 1 is turned to the starter output position is supplied to the signal line L3 of the ignition switch continuously for a predetermined period (for example, 2 seconds), The pseudo signal is transmitted to the engine control unit 7 (step S
20).

Then, after providing a standby time for a predetermined period (for example, 4 seconds) (step S21),
It is determined whether or not the engine has been started based on the alternator drive signal (step S
22), when it is judged that the engine is started, the remote starting flag f ₁ to 0 (step S23). On the other hand, if it is determined that the engine has not been started, the process returns to step S20,
The pseudo signal corresponding to the starter signal is transmitted again.

If it is determined in step S17 that the activation signal has been received again from the immobilizer unit 6, the same code as the vehicle-specific code has not reached the immobilizer unit 6, so that 1 is first added to the counter c ( (Step S24) Next, it is determined whether or not the counter c to which 1 is added is equal to or more than a predetermined value c '(for example, 10 times) (Step S25).

If it is determined that the counter c is less than the predetermined value c ', the process returns to step S16, and the EEPR
The code stored in the OM 36 is transmitted to the immobilizer unit 6 again. On the other hand, counter c
Is greater than or equal to the predetermined value c ′, that is, if the immobilizer unit 6 determines that the match is not determined despite the code stored in the EEPROM 36 being transmitted c ′ times,
It is considered that the code unique to the vehicle is not registered in the ROM 36 or the code has not normally reached the immobilizer unit 6 due to the influence of noise or the like, and the process directly proceeds to step S23 to set the remote start flag f ₁ . 0, and the processing operation [1] -1a ends.

Next, the processing operation [1] -2 (program processing of step S8 in FIG. 2) performed by the microcomputer 32 in the remote start control device 31 according to the embodiment (1) will be described based on the flowchart shown in FIG. . The processing operation [1] -2 is an operation for writing a vehicle-specific code registered in the chip 3 of the proper ignition key 1 into the EEPROM 36.

First, it is determined whether or not the activation signal supplied to the signal line L1 from the immobilizer unit 6 has been received (step S30). If it is determined that the activation signal has been received, the process proceeds to step S31.
On the other hand, if it is determined that the activation signal has not been received, the processing operation [1] -2 is terminated.

The start signal is supplied from the immobilizer unit 6 to the signal line L1 in the following two ways.
B) The driver inserts the ignition key 1 into the key cylinder 4 (or turns the ignition key 1 to the ACC output position or the IG output position of the ignition switch), and detects the key insertion from the key cylinder 4 to the signal line L3. When a signal is supplied.
B) When the driver presses the button switch 39a of the portable transmitter 37 and a pseudo signal such as a key insertion detection signal is supplied from the remote start control device 31 to the signal line L3. Incidentally, the flag f ₁ for remote starting is 1 in this case (see steps S11, S12 in FIG. 3).

In step S30, it is judged that it has received the start signal, then, for remote starting flag f ₁ determines whether it is 1 (step S31). A remote starting flag f ₁ is 1, that is, the key cylinder 4 when it is judged that the ignition key 1 is not inserted, ends the processing operation (1) -2.

On the other hand, for remote starting flag f ₁ is not 1, i.e., if it is determined that the ignition key 1 is inserted into the key cylinder 4, then supplied code from the transponder 5 to the signal line L2 (i.e., transponder 5 (A code obtained by performing wireless communication with the chip 3 of the ignition key 1) is determined (step S32).

If it is determined that the code has not been received, the process returns to step S32 to wait for the code to be transmitted. If determined that it has received the code, the timer t ₁ is set to 0 and started (step S33), then, based on the alternator drive signal, it determines whether the engine has been started (step S34 ).

The code supplied from the transponder 5 to the signal line L2 is received not only by the remote start control device 31 but also by the immobilizer unit 6, so that the code matches the vehicle-specific code (that is, the normal ignition key 1). Is inserted into the key cylinder 4)
, The permission signal is given to the engine control unit 7.

Therefore, when the proper ignition key 1 is turned to the starter output position,
The engine will start. In other words, if the start of the engine can be detected, it can be determined that the code is a code unique to the vehicle.

Therefore, if it is determined in step S34 that the engine has been started, it is determined that the code is a vehicle-specific code, and the code (vehicle-specific code) transmitted from the transponder 5 is stored in the EEPROM 36. (Step S35).

On the other hand, when it is judged that the engine has not been started, the period timer t ₁ is given T ₁ (e.g., 6 seconds) to determine whether or not elapsed (step S36), the period timer t ₁ is given T If it is determined that ₁ has not elapsed, the process returns to step S34, and it is determined again whether or not the engine has been started. On the other hand, when it is judged that the timer t ₁ has a predetermined period T ₁ has elapsed, without writing code into EEPROM 36, and ends the processing operation (1) -2.

The reason why the engine does not start during the predetermined period T ₁ is that the engine does not start even if the regular ignition key 1 is not inserted into the key cylinder 4 or even if the regular ignition key 1 is inserted into the key cylinder 4. by a period T ₁ of the passes, which if they are not rotated to the starter output position.

Further, here, the case where the received code is stored in the EEPROM 36 when the engine is started has been described. However, in another embodiment, the received code is stored in the EEPROM 36 every time the code is received regardless of the engine start. You may make it do. In that case, the processing operations of steps S33, S34, and S36 may be deleted.

According to the remote start control device according to the embodiment (1), the vehicle-specific code output based on the insertion of the ignition key 1 into the key cylinder 4 is stored in the EEPROM 36. When an engine start instruction is received by remote control, EEPRO
The code stored in M36 (that is, the code unique to the vehicle) is stored in the immobilizer unit 6.
To be supplied to

Therefore, even when the engine start instruction is given by remote control, the ignition key 1
The vehicle-specific code can be supplied to the immobilizer unit 6 in the same manner as in the case where is inserted into the key cylinder 4, and permission to start the engine can be given from the immobilizer unit 6. Thereby, even if the ignition key 1 is not inserted into the key cylinder 4 and turned,
An engine or the like can be started by remote control.

Further, according to the remote start control device according to the above-described embodiment (1), after the code stored in the EEPROM 36 is supplied to the immobilizer unit 6, it is determined whether or not the start signal has been output from the immobilizer unit 6 ( For example, after the code stored in the EEPROM 36 is supplied to the immobilizer section 6, it is determined whether or not the activation signal has been output from the immobilizer section 6 even if two seconds have elapsed.

When it is determined that the start signal has not been output from the immobilizer unit 6 (that is, the start of the engine has been permitted by the immobilizer unit 6), the output is performed when the ignition key 1 is turned to the starter output position. The pseudo signal corresponding to the starter signal is 2
The pseudo signal is transmitted to the signal line L3 of the ignition switch continuously for seconds, and transmitted to the engine control unit 7.

Therefore, only when the start of the engine is permitted, the process of transmitting the pseudo signal corresponding to the starter signal to the engine control unit 7 can be performed, so that the process is prevented from being wasted. be able to. As a result, the starter motor can be protected.

When the vehicle-specific code is output based on the insertion of the ignition key 1 into the key cylinder 4, the vehicle-specific code is automatically stored in the EEPROM 36. EEPR just by performing a normal start operation without any trouble
The OM 36 can store the vehicle-specific code.

Further, according to the remote start control device according to the first embodiment, when the code output based on the insertion of the ignition key 1 into the key cylinder 4 is stored in the EEPROM 36, whether or not the engine has been started is determined. Since it is checked whether an incorrect code is stored, it is possible to prevent the wrong code from being stored. Note that the present invention is not limited to the above embodiment,
For example, the start determination of the engine is applicable as long as the start can be determined, such as the engine speed.
