  2. Description of the Related Art Conventionally, in order to prevent theft of a vehicle, an antitheft device (so-called immobilizer) that prohibits / permits engine control for an engine control device based on communication with a vehicle key (ignition key) is known. .

  And as this kind of anti-theft device, when the ignition switch of the vehicle is turned on, it obtains the code stored in the transponder by wirelessly communicating with the transponder built in the vehicle key, It is known that the obtained personal identification code and the reference code are collated and the engine control device is allowed to control the engine when they match. The reference code is stored in the anti-theft device.

  On the other hand, in order to warm up the vehicle engine or operate the air conditioner with the vehicle key not inserted into the key cylinder, according to a remote operation command from the remote controller (remote controller), There is known a remote starter that drives a starter motor to start an engine.

  By the way, when the remote starter and the antitheft device are mounted on one vehicle, the engine is started after allowing the antitheft device to control the engine in response to a remote operation command from the remote controller. It has been proposed to configure a remote starter and to configure an anti-theft device so that the engine control unit is allowed to control the engine even when the remote starter receives a remote operation command.

  As a vehicle equipped with this type of remote starter and anti-theft device, a remote control password code for allowing the antitheft device to control the engine is stored in the remote starter and It is known that a remote operation reference code for collation with the operation code is stored in the anti-theft device, and that the remote starter device and the anti-theft device can communicate with each other. Yes.

In such a vehicle, when the remote starter receives a remote control command from the remote controller, the remote control password is transmitted to the antitheft device, and the antitheft device is used for remote control from the remote starter. The personal identification code and the remote operation reference code are collated, and when the two codes match, the remote starter is allowed to start the engine (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-198761

  However, in such a vehicle, when the engine is started by the remote starter, data communication is performed between the remote starter and the antitheft device in order to allow the antitheft device to control the engine and start the engine. There is a problem that the configuration of the device (and thus the vehicle) becomes complicated because it is necessary to check the code in the anti-theft device.

  The present invention has been made to solve these problems. When the anti-theft device and the remote starter are mounted on one vehicle, the configuration of each device is maintained while maintaining the security of the vehicle. The purpose is to simplify.

  The vehicle antitheft device according to claim 1, which has been made to solve the above problem, is provided in a vehicle provided with a remote start means for starting an engine when receiving a remote start command transmitted wirelessly from outside. This is to prevent the vehicle from being stolen.

  In the vehicle antitheft device according to claim 1, when the engine is started by the remote starting means, the user determining means subsequently acquires identification information relating to an operator who operates the vehicle, and acquires the information. Based on the identified information, it is determined whether or not the operator is a regular user registered in advance. When the user determination means determines that the operator is a regular user, the travel prohibition means permits the vehicle to travel, and conversely, the user determination means allows the operator to If it is determined that the vehicle is not a person, the travel prohibiting means prohibits the travel of the vehicle.

  In the antitheft device for a vehicle according to claim 1 as described above, when the vehicle is manually operated when the engine is started by the remote starting means, the vehicle is run when the operator is a regular user. to approve.

  Therefore, according to the vehicle antitheft device of the first aspect, the remote operation reference code is stored in advance, or the remote operation code and the remote operation reference are stored when the engine is started by the remote starting means. The engine can be started by the remote starting means while maintaining the security of the vehicle without executing the process for checking the code.

Therefore, the configuration of the device (and thus the vehicle) can be simplified while maintaining the security of the vehicle.
Further, in order to prohibit the traveling of the vehicle by the travel prohibiting means when the user determining means determines that the operator is not an authorized user, the engine is stopped as described in claim 2. Alternatively, as described in claim 3, the engine speed may be limited to a predetermined value or less.

In this way, traveling of the vehicle can be reliably prohibited.
By the way, when the engine is started by the remote starting means, it is conceivable that the vehicle is manually operated by a suspicious person (that is, an operator who is not a regular user).

  Therefore, in the vehicle antitheft device according to any one of claims 1 to 3, the travel prohibiting means is determined by the user determining means that the operator is not a regular user, as described in claim 4. When the vehicle is prohibited from traveling, it is preferable that the remote start means start the engine until the engine is started by a manual operation of a regular user.

  In this way, even if the suspicious person transmits the remote start command and starts the engine because the remote start command is stolen to the suspicious person, the travel prohibition means prohibits the engine start by the remote start means. In some cases, the engine can be started only by an authorized user, so that security can be improved.

  Further, the vehicle antitheft device according to claim 5 is the vehicle antitheft device according to any one of claims 1 to 4, wherein when the engine is started by the remote start means, the vehicle is manually operated thereafter. Driving determination means for determining whether or not the vehicle has been operated is provided. When the driving determination means determines that the vehicle has been manually operated, the user determination means acquires identification information from the operator, and the acquired identification information. Based on the above, it may be configured to determine whether or not the operator is an authorized user registered in advance.

According to this, the user determination means can determine whether or not the operator is an authorized user when the vehicle is manually operated.
In addition, when the driving determination means determines that the vehicle has been manually operated, the brake state detection means for detecting the parking brake operation state of the vehicle is provided as described in claim 6, The shift position detecting means for detecting the shift position in the transmission of the vehicle may be provided as described in claim 7, wherein the determination may be made when the operation state of the parking brake detected by the state detecting means changes. The determination may be made when the shift position detected by the shift position detecting means changes. According to another aspect of the present invention, there is provided seating detection means for detecting that a person is sitting on the vehicle seat, and when the seating detection means detects that a person is seated on the vehicle seat, It may be determined that the vehicle has been manually operated. As described in claim 9, accelerator detection means for detecting that the accelerator pedal of the vehicle has been operated is provided, and the accelerator pedal of the vehicle is operated by the accelerator detection means. It may be determined that the vehicle has been manually operated when it has been detected.

In any of the vehicle antitheft devices according to the sixth to ninth aspects, it can be accurately determined that the vehicle has been manually operated.
Still further, the vehicle antitheft device of the present invention is provided with all the detection means according to claims 6 to 9, and the driving determination means is operated manually by the vehicle according to the detection result of any of the detection means. When it is determined that the vehicle has been operated, the vehicle may be determined to be manually operated.

In this way, it can be determined more accurately that the vehicle has been manually operated.
By the way, in the user determination means, personal information such as a legitimate user's fingerprint and retina is stored in advance, and whether the legitimate user is obtained by obtaining the fingerprint from an operator who manually operates the vehicle. It may be determined whether or not.

However, in this case, it is necessary to newly provide means for acquiring personal information such as fingerprints and retinas, and the configuration of the apparatus becomes complicated.
Therefore, the vehicle antitheft device according to any one of claims 5 to 9 receives a transmission signal transmitted from a vehicle key for operating the vehicle, and receives the received signal as described in claim 10. And a key determination means for determining whether or not the vehicle key is a regular key, and when the driving determination means determines that the vehicle has been manually operated, the determination result by the key determination means When the vehicle key is a regular key, the operator may determine that the operator is a regular user.

According to this, since the vehicle key used in what is called a keyless entry system should just be used as it is, the said apparatus is easily realizable.
Further, in the vehicle antitheft device according to claim 10, the driving determination means starts the engine in a state where the key determination means has not received the transmission signal from the vehicle key as described in claim 11. In this case, it is preferable that it is determined that the engine has been started by the remote starting means, and then it is determined whether or not the vehicle has been manually operated.

  In this way, for example, even when the user mounts the remote starter as a retrofit on a vehicle equipped with the vehicle antitheft device of the present invention, the user can remotely The engine can be started by the starting means.

  Further, in the vehicle antitheft device according to claim 11, when the driving determination means determines that the engine is started by the remote start means as described in claim 12, the key determination means transmits the vehicle key. It may be configured to determine that the vehicle has been manually operated when the signal is received.

According to this, the travel prohibiting means can start the operation earlier, and the user can smoothly start driving (running) the vehicle.
Next, a vehicle remote starter according to a thirteenth aspect is used as a remote starter in a vehicle equipped with the vehicle antitheft device according to any one of the first to twelfth aspects.

  In the remote starter for a vehicle according to claim 13, when a remote operation command is transmitted from a portable device possessed by the user of the vehicle, the receiving means provided in the vehicle receives the remote operation command. And the remote control means provided in the vehicle starts the engine.

  According to the remote starter for a vehicle according to the thirteenth aspect as described above, the engine can be started simply by transmitting a remote control command without storing the remote control code.

Therefore, similarly to the effects of the first to twelfth aspects, the configuration of the device (and thus the vehicle) can be simplified while maintaining the security of the vehicle.
According to a thirteenth aspect of the present invention, there is provided the vehicle remote starter as described in the fourteenth aspect, wherein a first condition determination is made to determine whether or not the shift position of the vehicle transmission is at a position where the vehicle cannot travel. And the remote control means starts the engine when the receiving means receives the remote operation command and at least the first condition determining means determines that the shift position is at a position where the vehicle cannot travel. It is preferable that it is comprised so that it may make it.

  In other words, when the engine is started by the vehicle remote starter of the present invention, if the shift position is at a position where the vehicle can run, the vehicle may start. If the starting device is configured as in the fourteenth aspect, this problem can be solved in advance, and deterioration of the in-vehicle battery and the starter motor can be suppressed.

  According to a thirteenth or fourteenth aspect of the present invention, the vehicle remote starter includes a second condition determining means for determining whether or not the vehicle has a parking brake applied. The remote control means is configured to start the engine when it is determined that the parking brake is applied at least by the second condition determining means when the receiving means receives the remote operation command. It is preferable.

  That is, if the parking brake is released when the engine is started by the vehicle remote starter of the present invention, the vehicle may move due to vibration at the time of engine start. If the starting device is configured as in the fifteenth aspect, this problem can be solved and the deterioration of the in-vehicle battery and the starter motor can be suppressed.

  The remote starter for a vehicle according to any one of claims 13 to 15 includes third condition determining means for determining whether or not a person is sitting on a seat of the vehicle as described in claim 16. The remote control means is configured to start the engine when at least the third condition determining means determines that no person is sitting on the seat when the receiving means receives the remote operation command. It is preferable.

  In other words, since it is not preferable in terms of security that the engine is started by the vehicle remote starter of the present invention when a suspicious person has entered the vehicle, the vehicle remote starter of the present invention is defined in claim 16. With this configuration, security can be maintained.

Next, the vehicle remote starter according to claim 17 is the vehicle remote starter according to any of claims 13 to 16, comprising a transmission means for transmitting information to the portable device, The remote control means is characterized by detecting the state inside the vehicle after starting the engine and transmitting the detection result to the portable device via the transmission means.

FIG. 5 is a flowchart showing processing executed by the microcomputer 49 of the remote start ECU 40, and FIG. 6 is a flowchart showing remote control notification information transmission processing executed by the microcomputer 49 of the remote start ECU 40.

First, processing executed by the microcomputer 26 of the immobilizer ECU 20 will be described.
When the microcomputer 26 of the immobilizer ECU 20 executes the process shown in FIG.

If it is determined in S110 that the password has been received from the communication unit 10, it is determined that communication with the vehicle key 2 has been performed, and the process proceeds to S120.
In S120, the personal identification code and the reference code are collated, and the collation result is stored in the RAM.

In S130, it is determined whether or not a verification request from engine ECU 30 has been received.
If it is determined in S130 that the collation request has not been received, the process proceeds to S135 to determine whether an engine stop notification has been received. If it is determined in S135 that the engine stop notification has not been received, the process returns to S130. Conversely, if it is determined that the engine stop notification has been received, the process proceeds to S160.

On the other hand, if it is determined in S130 that the collation request has been received, the process proceeds to S140, and the collation result stored in the RAM is transmitted to the engine ECU 30.
Subsequently, in S150, the process waits until an engine stop notification is received from the engine ECU 30, and when the engine stop notification is received, in S160, the collation result stored in the RAM is reset, and the process returns to S110.

On the other hand, if it is determined in S110 that the password has not been received from the communication unit 10, it is determined that communication with the vehicle key 2 has not yet been performed, and the process proceeds to S170.
In S170, it is determined whether or not a collation request from engine ECU 30 has been received. If it is determined that a collation request has not been received, the process returns to S110, and conversely, if it is determined that a collation request has been received. Advances to S180.

In S180, a communication incomplete notification is transmitted to engine ECU 30, and the process proceeds to S160.
Next, processing executed by the microcomputer 38 of the engine ECU 30 will be described.

  When the microcomputer 38 of the engine ECU 30 is activated by turning on the IGSW 8, as shown in FIG. 3, it is first determined in S210 whether or not a remote start command has been received from the remote start ECU 40.

  If it is determined in S210 that the remote start command has been received, it is determined that the current start is by the remote start ECU 40, the process proceeds to S220, and conversely, the remote start command has been received. If it is determined that there is not, it is determined that the current activation is due to the operation of the vehicle key 2, and the process proceeds to S320.

  In S220, it is determined whether the engine can be started. If it is determined that the engine can be started, the process proceeds to S230. On the other hand, if it is determined that the engine should not be started, the process proceeds to S235, a start disapproval notice indicating that the current engine start is not permitted is transmitted to the remote start ECU 40, and the process proceeds to S310.

  The process of S220 will be described in detail. In this process, first, based on the accelerator opening signal, the shift position signal, and the vehicle speed signal, whether or not the accelerator pedal is stepped on and the current shift position indicates that the vehicle cannot travel. Whether the vehicle speed is “0” (that is, the wheel is not rotating).

  If at least one of the three determination processes is a negative determination, it is determined that the engine should not be started (S220: NO), and the process proceeds to S235. On the other hand, if the determination is positive in all the determination processes, a parking brake signal is acquired from the remote start ECU 40, and it is determined whether the parking brake is applied based on the signal.

  If it is determined that the parking brake is not applied, it is determined that the engine should not be started (S220: NO), and the process proceeds to S235. On the other hand, if it is determined that the parking brake is applied, the door opening / closing signal, the seating signal, and the steering signal are acquired from the body ECU 50, and based on these signals, whether the door is not opened, the seat It is determined whether or not there is a person sitting on the wheel and whether or not the steering (steering wheel) is operated.

  If at least one of the three determination processes is a negative determination, it is determined that the engine should not be started (S220: NO), and the process proceeds to S235. On the other hand, if an affirmative determination is made in all determination processes, it is determined that the engine may be started (S220: YES), and the process proceeds to S230.

  That is, in S220, the accelerator pedal is not depressed, the current shift position is in a position where the vehicle cannot travel, the vehicle speed is “0”, and the parking brake is applied. If all the following conditions are met: the door is not opened, no one is seated in the seat, and the steering is not operated, it is determined that the engine can be started. .

Next, in S230, the starter motor 80 is driven.
In the present embodiment, when the starter motor 80 is driven, the microcomputer 38 executes an engine start time control process different from the process. In this engine start-up control process, a well-known engine control process is performed while limiting the engine speed to a speed at which the vehicle cannot travel (for example, 500 revolutions). Thereby, for example, even if a suspicious person who has entered the vehicle operates the accelerator pedal or the shift lever to perform the driving operation of the vehicle, the vehicle does not travel.

Subsequently, in S240, vehicle operation detection processing (see FIG. 4) is executed, and when it is detected that the vehicle is manually operated, the process proceeds to S250, and a verification request is transmitted to the immobilizer ECU 20.
Then, the verification result or the communication incomplete notification is transmitted from the immobilizer ECU 20 to the engine ECU 30.

In subsequent S260, it is determined whether or not the collation result acquired from the immobilizer ECU 20 indicates that the password code and the reference code match (that is, collation OK).
If it is determined in S260 that the verification is OK, the process proceeds to S265.

  In S265, the engine start-time control process is terminated, and a normal engine control process is started in which the limitation on the rotational speed is removed from the process. Thereby, the user who operates the vehicle can drive the vehicle.

  The engine control process is also a process different from the process shown in FIG. 3 as in the engine start time control process. Further, the microcomputer 38 sends an engine stop notification to the immobilizer ECU 20 (when the user performs a stop operation for stopping the engine in the engine control process (that is, when a user-side engine stop command is input). If the current start is by the remote start ECU 40, it is transmitted to the immobilizer ECU 20 and the remote start ECU 40), and the engine is stopped by stopping the drive of the fuel injection valve 82 and the igniter 84, and the engine control processing. Exit.

  Then, in S270, the collation result acquired from immobilizer ECU20 is transmitted to remote start ECU40, and it progresses to S280. In S270, if the current activation of the microcomputer 38 is not performed by the remote start ECU 40, the collation result acquired from the immobilizer ECU 20 is not transmitted to the remote start ECU 40.

In S280, the process waits until the IGSW 8 is turned off. When the IGSW 8 is turned off, the process is terminated (ie, the operation is stopped).
