Description

  The present invention relates to a start control device and a tuner device that perform remote start of a vehicle, and more particularly to a start control device and a tuner device that can extend a remote startable distance by retrofitting a tuner device.

  Conventionally, the door of a vehicle is locked / unlocked and the engine is started by a physical rotation of the key, but the key has a short-range wireless communication function for easy locking / unlocking of the door. It is now common to be able to lock and unlock electrically.

  Such a key having a wireless communication function is called a remote key or a wireless key. Recently, an attempt has been made to extend the remote control of the vehicle by the wireless communication until the engine is started.

  In the technology for starting the engine remotely, a start control device is incorporated in the vehicle, and the engine is started when the start control device receives a start request from the outside by wireless communication (for example, Patent Documents 1 to 3). 6).

Japanese Patent Laid-Open No. 11-198761 Japanese Patent Laid-Open No. 11-230013 JP-A-8-247909 Japanese Patent Laid-Open No. 10-21868 JP 2005-180249 A JP 2005-29119 A

  As a method for the start control device to receive a start request from outside by wireless communication, there are a method using a remote key and a method using a dedicated remote controller.

  The remote key is originally intended for door lock control (locking / unlocking) and alarming around the vehicle (panic alarm), so when starting the engine with such a remote key, for example, a door lock request is transmitted. A command operation such as pressing the button to perform three times in succession is regarded as an engine start request.

  In this way, the method using the remote key can reduce the cost of the remote starting device because the controller itself and the tuner for receiving a signal from the controller are not necessary in comparison with the method using the dedicated controller. There are benefits.

  However, the remote key is only supposed to be used at a close distance (for example, about 5 m), and there is a problem that the remote startable distance is short and the convenience is low.

  Therefore, in the initial state, it has been required to adopt a method using a remote key to reduce the cost and to allow the user to change the configuration so that the dedicated controller can be used as necessary.

  The present invention has been made to solve the above-described problems in the prior art and to solve the problems, and provides a start control device and a tuner device capable of improving functions as necessary while suppressing initial investment. For the purpose.

  In order to solve the above-described problems and achieve the object, a start control device according to the present invention is wirelessly transmitted from a remote controller and a reception unit that receives an engine start request based on a first signal wirelessly transmitted from a remote key. A tuner connection means that can connect an external tuner that receives a second signal indicating an engine start request, a case where an engine start request based on a first signal transmitted wirelessly from a remote key is received, and a wireless transmission from a remote controller When the engine start request indicated by the second signal is input via the tuner connecting means, the engine is started.

  The tuner device according to the present invention is externally connected to a start control device mounted on a vehicle, and when receiving a signal wirelessly transmitted from a remote controller, inputs the engine start request to the start control device. The engine is started.

  According to the present invention, the start control device can connect an external tuner capable of receiving a signal from the remote controller to the tuner connecting means, and when receiving an engine start request based on the first signal from the remote key, The engine is started regardless of whether the engine start request indicated by the second signal from the controller is input. For this reason, remote start using a remote key is possible, and remote start using a remote controller can be performed by connecting an external tuner if necessary. At this time, since one start control means can be shared by the remote start using the remote key and the remote start using the remote controller, a start control device capable of improving functions as necessary while suppressing initial investment is obtained. be able to.

  Further, according to the present invention, the tuner device can be externally connected to the start control device mounted on the vehicle, and receives a signal indicating an engine start request from the remote controller and inputs it to the start control device. The vehicle engine is started. Therefore, a tuner device that can improve the function of the start control device can be provided at a relatively low cost.

  Hereinafter, an in-vehicle system that is a preferred embodiment of a start control device and a bidirectional tuner according to the present invention will be described in detail with reference to the accompanying drawings.

  First of all, the in-vehicle system configuration includes a mechanical type configuration in which a key is inserted into a key cylinder at the time of manual engine start and the engine is started by turning, and a so-called push operation in which the engine is started by button operation regardless of the key. There is an electronic configuration called a start method. In this embodiment, first, the case where the present invention is applied to a mechanical structure will be described with reference to FIGS. 1 to 5, and then the present invention is applied to an electronic structure with reference to FIG. Will be described.

  FIG. 1 is a schematic configuration diagram showing a schematic configuration when the present invention is applied to an in-vehicle system 10 having a mechanical configuration. As shown in the figure, the in-vehicle system 10 is connected to a bus network 11 with a body ECU (Electrical Control Unit) 12 and an engine control ECU (so-called EFi) 15.

  A remote key tuner 13, a door lock motor 14 and a remote start ECU 20 are further connected to the body ECU 12, and an immobilizer 16 is connected to the engine ECU 15 and the remote start ECU 20.

  The immobilizer amplifier 17 connected to the immobilizer 16 is disposed in the vicinity of the key cylinder 18 into which the vehicle key 5 is inserted.

  The engine control ECU 15 is a control device that electronically controls the operation of the engine. Specifically, the engine control ECU 15 starts the operation corresponding to the connection of the ignition line (IG), and detects that the starter motor (not shown) starts rotating in response to the connection of the starter line (ST). The engine is started and operated by performing fuel injection and ignition control. Further, when the ignition line (IG) is opened, the fuel injection is finished and the engine is stopped.

  Here, the engine control ECU 15 acquires information on the state of the engine, for example, the engine speed, and uses it for engine control. Further, the engine control ECU 15 is connected to the bus network 11, communicates with the body ECU 12 and the like via the bus network 11, receives output information of each ECU, and transmits input information of the engine control ECU 15.

  Further, the engine control ECU 15 is connected to the immobilizer 16. The immobilizer 16 is a device that prevents the vehicle from being stolen by providing authentication information (code) to the vehicle key (here, key 5), and reads the code when the insertion of the key into the key cylinder 18 is detected. To authenticate. When the authentication is unsuccessful, the engine start is prohibited, and only when the authentication is successful, the start prohibition is canceled to prevent the vehicle from being stolen by an unauthorized engine start.

  Specifically, in order to cancel the prohibition of starting the engine by the immobilizer 16, first, the key cylinder 18 detects the insertion of the key 5 and notifies the immobilizer 16 (procedure 1). The immobilizer 16 that has received the notification makes a key code transmission request to the immobilizer amplifier 17 (procedure 2). Then, the immobilizer amplifier 17 performs wireless communication with the key 5, reads the key code stored in the transponder built in the key 5, and transmits it to the immobilizer 16 (procedure 3). The immobilizer 16 determines whether the key code received from the immobilizer amplifier 17 matches the key code stored in advance, and gives a start permission to the engine control ECU 15 as a successful authentication if they match, thereby prohibiting the engine from starting. Release (procedure 4).

  Therefore, when the user inserts the regular key 5 into the key cylinder 18, the immobilizer 16 automatically cancels the prohibition of starting the engine, and the user operates the ignition line, the starter line, or the in-vehicle device by rotating the key 5. By operating an accessory line (ACC) that manages power supply to the engine and driving the starter motor, the engine control ECU 15 performs fuel control and ignition control to start the engine. On the other hand, when an incorrect key is inserted into the key cylinder 18, the key code in the immobilizer 16 cannot be matched, so the engine control ECU 15 is in a start-inhibited state, and the starter motor is driven by the key turning operation. However, the engine control ECU 15 does not operate and the engine does not start.

  The body ECU 12 is a control device that controls the state of the vehicle body, and in particular, locks and unlocks the vehicle door by controlling the operation of the door lock motor 14. The body ECU 12 is connected to the remote key tuner 13 and the bus network 11, and outputs the input information to the bus network 11 and communicates with the engine control ECU 15 via the bus network 11.

  The remote key tuner 13 communicates with the remote key 1 via an antenna. The remote key 1 is a remote operation terminal possessed by the user, and transmits a door locking request and unlocking request, and an alarm output request for the vicinity of the vehicle to the in-vehicle system 10. On the other hand, the key 3 is used when the user directly starts the engine. In general, the key 5 has the function of the remote key 1 to be integrated.

  Further, a remote start ECU 20 is connected to the body ECU 12. When the body ECU 12 receives various vehicle control requests (door lock request, door unlock request, alarm (panic alarm) request, etc.) from the remote key tuner 13, the body ECU 12 performs control based on the received control request (door lock, (Unlock, panic alarm) is executed, and the received control request is transmitted to the remote start ECU 20 as it is.

  The remote start ECU 20 performs a process of starting the engine in a state where the key 5 is not inserted into the key cylinder 18, that is, the user is outside the vehicle. At this time, in order to cancel the prohibition of starting the engine by the immobilizer 16, the remote start ECU 20 stores information for authentication having the same function as the key code held by the key 5 as an immobilizer code.

  The remote start ECU 20 includes a command identification unit 21, a tuner connection unit 22, and a main control unit 23 therein. The main control unit 23 further includes a door lock control unit 24, a notification processing unit 25, and a start control. Part 26.

  The command identifying unit 21 performs processing for identifying whether or not the control request received from the body ECU 12 forms a command. In this command, for example, when a door lock request is made three times in succession (the first time, the second time is short, and the third time is long), the series of requests is regarded as an engine start request. By recognizing a combination of vehicle control requests as a command, other control (in this case, engine start) is performed using the remote key 1 that originally has only the function of requesting locking and unlocking of doors and alarms around the vehicle. Can be done. It should be noted that the commands shown here are merely examples, can be changed as appropriate, and commands that require control other than engine start can also be formed.

On the other hand, the tuner connection unit 22 is a connection means for external connection with the bidirectional tuner 3. The tuner connection unit 22 includes a connector to which a transmission cable can be connected and a transmission circuit that transmits a signal. The bidirectional tuner 3 and the remote start ECU 20 are capable of bidirectional communication by being physically connected by a transmission cable such as a wire harness. Such a transmission cable is coupled to the connector of the tuner connection portion 22. A signal from the bidirectional tuner 3 is input to the tuner connection unit 22 via this connector, and is further transmitted to the main control unit 23 by the transmission circuit of the tuner connection unit 22. The transmission circuit only needs to have a function of correctly transmitting signals between the connector and the main control unit 23. Therefore, the tuner connection portion 22 can be configured with a relatively simple configuration. That is, the tuner connection unit 22 can be realized at a relatively low cost, and even if the remote start ECU 20 includes the tuner connection unit 22, the cost of the remote start ECU 20 does not increase significantly.
The bidirectional tuner 3 communicates with the bidirectional remote controller 2 having a longer communication distance than the remote key 1. The bidirectional tuner 3 inputs the received content to the tuner connection unit 22 when a control request such as engine start is received from the bidirectional remote controller 2 by this wireless communication. The control request input to the tuner connection unit 22 in this way is further input to the main control unit 23 by the tuner connection unit 22. The bidirectional tuner 3 also receives a transmission request from the remote start ECU 20 via the tuner connection unit 22 and transmits information such as the vehicle state to the bidirectional remote controller 2 by wireless communication.

  Unlike the remote key 1, the bidirectional remote controller 2 is a remote operation terminal that is supposed to perform remote control of the engine. Therefore, a dedicated operation button for transmitting an engine start request can be provided. A control signal dedicated to the start request can be transmitted.

  Therefore, the remote start ECU 20 is started regardless of whether the vehicle control request transmitted from the remote key 1 forms an engine start command or when the engine start request is received from the bidirectional remote controller 2. The engine start control by the control unit 26 is executed. That is, the start control unit 26 is shared by remote start using a remote key and remote start using the bidirectional remote controller 2. Both the signal related to the request from the remote key 1 and the signal related to the request from the bidirectional remote controller 2 are input to the start control unit 26. In order to ensure the input of these two signals, the communication protocol for the signal related to the request from the remote key 1 and the communication protocol for the signal related to the request from the bidirectional remote controller 2 are different communication protocols. Is desirable.

  Here, a procedure when the engine is started by the start control unit 26 will be described. First, it is recognized that the engine start is requested from the remote key 1 or the bidirectional remote controller 2 (procedure 1). Next, in response to the start request, a release request is made to the immobilizer 16 (procedure 2). The immobilizer 16 authenticates the remote start ECU 20 in response to the release request. If the authentication is successful, the immobilizer 16 grants start permission to the engine control ECU 15 and notifies the remote start ECU 20 that start prohibition has been released (procedure 3). . Thereafter, the remote start ECU 20 performs engine start control by operating the accessory line, the ignition line, and the starter line and outputting pseudo signals, respectively (procedure 4).

  By the way, the bidirectional remote controller 2 can transmit not only the engine start control request but also any vehicle control request (door lock request, door unlock request, alarm (panic alarm) request, etc.). For example, when the bidirectional remote controller 2 transmits a door locking request or unlocking request, the door lock control unit 24 in the main control unit 23 receives this control request and locks or unlocks the door to the body ECU 12. Request. Similarly, when the bidirectional remote controller 2 transmits an alarm request, the main control unit 23 receives this control request and requests the body ECU 12 to perform a panic alarm.

  The body ECU 12 executes control (for example, operation control of the door lock motor 14) in the same manner as when the vehicle control request is received from the remote key tuner 13 even when the vehicle control request is received from the remote start ECU 20. Although the vehicle control request received from the remote key tuner 13 is notified from the body ECU 12 to the remote start ECU 20, it is desirable that the vehicle control request received from the remote start ECU 20 is not notified to the remote start ECU 20.

  Further, the remote start ECU 20 can notify the bidirectional remote controller 2 of information. For notification of this information, the notification processing unit 25 in the main control unit 23 transmits a signal indicating information to be notified to the bidirectional tuner 3 via the tuner connection unit 22 and the transmission cable. Is performed by transmitting the signal to the bidirectional remote controller 2 by wireless communication. As the contents to be notified, it is possible to notify the control result by the start control unit 26 and the door lock control unit 24, arbitrary information about the vehicle such as the vehicle state and the diagnosis information.

  Regarding the notification of the control result, when the engine start request is received from the bidirectional remote controller 2 and the start control is performed, the control result is notified to the bidirectional remote controller 2. However, when the engine start request command is received from the remote key 1 and the start control is performed, the remote key 1 does not have a function of receiving information. In this case, the notification of the control result may not be performed, but the bidirectional remote controller 2 may be configured to notify the result of the control performed in response to an instruction from the remote key 1.

  Next, the processing operation based on the control request from the remote key 1 will be described with reference to FIG. As shown in the figure, first, the remote key tuner 13 receives a signal transmitted by the remote key 1 (step S101), and the body ECU 12 controls the door lock motor 14 based on the received signal and also receives the received signal. To the remote start ECU 20 (step S102).

  The command identification unit 21 in the remote start ECU 20 determines whether or not the received signal forms a command (step S103), and if the command is not established (step S104, No), the process is ended as it is.

  On the other hand, if the command is established (step S104, Yes), start control is executed based on the established command (step S105), and the control result is notified to the bidirectional remote controller 2 (step S106). The process ends.

  Next, a processing operation based on a control request from the bidirectional remote controller 2 will be described with reference to FIG. As shown in the figure, first, the bidirectional remote tuner 3 receives a signal transmitted from the bidirectional remote controller 2 (step S201), and the bidirectional tuner 3 is a signal transmitted from a regular bidirectional remote controller. Is authenticated (step S202). This authentication is performed based on whether or not the authentication code included in the signal transmitted by the bidirectional remote controller 2 matches the authentication code stored in the bidirectional tuner 3 in advance.

  If this authentication fails (when it cannot be confirmed that the signal is transmitted from a legitimate controller) (step S203, No), the processing is terminated as it is.

  On the other hand, when the authentication is successful (when it is confirmed that the signal is transmitted from a legitimate controller) (step S203, Yes), the bidirectional tuner 3 remotely starts the received signal via the tuner connection unit 22. It passes to ECU20 (step S204).

  The remote start ECU 20 executes control based on the received command, specifically, door lock control and start control (step S205), notifies the bidirectional remote controller 2 of the control result (step S206), and performs processing. finish.

  The bidirectional tuner 3 and the bidirectional remote controller 2 can be retrofitted to the in-vehicle system 10, and the bidirectional tuner 3 is not always connected to the tuner connection unit 22.

  However, when the bidirectional tuner 3 is not connected, the remote key 1 can be used to remotely start the engine. When the bidirectional tuner 3 is connected, the bidirectional remote controller 2 can be used to remotely start the engine from a long distance.

  Thus, the engine start control can be performed regardless of whether or not the bidirectional tuner 3 is connected, and the processing operation of the remote start ECU 20 is the same regardless of whether or not the bidirectional tuner 3 is connected.

  Therefore, in the initial state, the cost can be reduced as a configuration in which the bidirectional tuner 3 is not connected, and the user can easily retrofit the bidirectional tuner 3 as necessary to improve the function.

  Here, the bidirectional remote controller 2 is authenticated by the bidirectional tuner 3, and the received signal is provided to the remote start ECU 20 only when it is authenticated as a legitimate controller. It is good also as giving to ECU20 side.

  When the two-way tuner 3 is connected, it is possible to extend the distance that can be remotely started, and to provide information to the user side is one of the functional improvements. Information to be provided to the user includes not only the control result of the remote control but also the status of the vehicle at that time, specifically the operating status of the engine, the open / closed status of the doors and windows, the room temperature, and whether there is any abnormality. is there. Furthermore, diagnostic information such as an abnormal engine stop history can also be notified.

  A specific example of the engine stop factor is shown in FIG. As shown in the figure, when the engine is started by remote control, the door is opened, the door is unlocked, the engine room hood is opened, the shift lever is other than P, the brake When the operation is performed, the check engine lamp is lit, the engine speed is higher, the vehicle speed is generated, the engine is not started, and the operation is terminated if the engine is operating.

  The engine stop history is stored in the remote start ECU 20 and can be transmitted in response to a request from the bidirectional remote controller 2.

  Further, here, the diagnosis information managed by the remote start ECU 20 has been described as an example, but diagnosis information other than the remote start managed by another ECU may be further acquired and transmitted to the bidirectional remote controller 2. good.

  Next, a specific configuration example of the bidirectional tuner will be described with reference to FIG. In the configuration example shown in the figure, the bidirectional tuner 3 includes a control microcomputer 31, a communication interface 32, an EEP-ROM 33, a receiver 34a, a transmitter 34b, and a switch 35 therein.

  The control microcomputer 31 is a control unit that controls the bidirectional tuner 3 as a whole, and has an authentication function for authenticating the bidirectional remote controller 2 that is a signal transmission source. The communication interface 32 is an interface for transmitting / receiving data to / from the remote start ECU 20. The communication interface 32 is physically connected externally to the tuner connection unit 22 of the remote start ECU 20 via a transmission cable, so that the bidirectional tuner 3 can communicate with the remote start ECU 20 in both directions. Specifically, a signal indicating a vehicle control request such as an engine start control request is transmitted from the bidirectional tuner 3 to the remote start ECU 20 via a transmission cable. On the other hand, a signal indicating a control result based on the vehicle control request and other information related to the vehicle is transmitted from the remote start ECU 20 to the bidirectional tuner 3 via the transmission cable. Although the transmission cable can be used for two-way communication in this way, the transmission path may be composed of a single path or a plurality of paths. The EEP-ROM 33 is a storage area used for storing an authentication code and the like.

  The receiver 34a and the transmitter 34b are specifically configured by an IC 34. The receiver 34a performs a reception process from the bidirectional remote controller 2, and the transmitter 34b performs a transmission process to the bidirectional remote controller 2.

  The transmission process and the reception process are switched by the switch 35, and the switch 35 is switched by a control signal from the control microcomputer 31.

  Next, a schematic configuration when the present invention is applied to an electronic configuration will be described with reference to FIG. In the configuration shown in the figure, the in-vehicle system 10 a connects the body ECU 12, the engine control ECU 15, the verification ECU 41, and the power supply ECU 42 to the bus network 11.

  The body ECU 12 is connected to the door lock motor 14 and the remote start ECU 20, and the remote key tuner 13 is connected to the verification ECU 41.

  A plurality of antennas provided inside and outside the vehicle are connected to the remote key tuner 13 (only one is shown in FIG. 6 for convenience), and communicates with the remote key 1 and receives from the remote key 1. Outputs signal and information indicating which antenna is received.

  The verification ECU 41 is an ECU having an immobilizer function, and determines whether or not the remote key 1 is in the vehicle based on the output signal of the remote key tuner 13, that is, based on the antenna that has received the signal from the remote key 5. At the same time, engine start is prohibited / cancelled. Further, the verification ECU 41 electronically confirms whether or not the remote key 1 is valid by verifying the code held by the remote key 1.

  The power supply ECU 42 is a control device that controls the start control for the engine control ECU 15, and is connected to a push switch 43 that replaces the engine start operation by a key, and is connected to the engine control ECU 15 to connect to an accessory line (ACC) and an ignition line (IG ), The starter line (ST) is controlled.

  The procedure for starting the engine by operating the push switch 43 will be described. First, when the remote key tuner 13 communicates with the remote key 1 and the verification ECU 41 detects that the remote key 1 is in the vehicle, the remote key 1 is authenticated. Perform (Procedure 1). If the authentication is successful, the engine start prohibition is canceled by giving a start permission to the engine control ECU 15 (procedure 2). When the user operates the push switch 43, the power supply ECU 42 controls the accessory line (ACC), ignition line (IG), and starter line (ST) to start the engine (procedure 3).

  Also in this in-vehicle system 10a, the configuration of the remote start ECU 20 is the same as that in the case of being installed in the in-vehicle system 10 shown in FIG. 1, and performs the same operation. Therefore, in the initial state, the bidirectional tuner 3 is not connected, and the remote start using the remote key 1 is performed to reduce the cost, and the bidirectional tuner 3 can be easily retrofitted as necessary. Can be improved.

  As described above, in the in-vehicle system according to the present embodiment, the remote start ECU 20 is provided with the command identification unit 21 and the tuner connection unit 22 and receives an engine start request from the remote key 1 as a command based on a combination of vehicle control requests. Even when an engine control request is received from the bi-directional remote controller 2, it is possible to execute the start-up control in the same manner, and the bi-directional tuner 3 can be easily retrofitted to reduce initial investment. Accordingly, it is possible to provide a start control device and a tuner device capable of improving functions accordingly. In the above-described embodiment, the remote controller 2 and the tuner 3 are configured to be able to communicate in both directions. However, they may be configured to be able to communicate from the remote controller 2 to the tuner 3 in one direction.

  As described above, the start control device according to the present invention is useful for vehicle start control, and is suitable for cost reduction and function improvement in the remote start function mounting.
