  As described above, the OBD function of the ECU is based on the premise that a failure code is read by a diagnostic tool at a sales dealer or the like. Although the ECU has an indicator lamp that flashes at the timing corresponding to the fault code, in order to identify the fault code from the flashing state, it is necessary to refer to the manual that shows the correspondence between the two. This is a task that is practically impossible for users of complex vehicles. For this reason, even if the user feels uncomfortable with his / her vehicle, the user cannot grasp the details of the abnormality, and inevitably knows whether the driver should take action or the abnormality is serious. .

  Therefore, even if it is a minor abnormality that allows the vehicle to continue running, it can be stopped or, conversely, even if it is a serious abnormality that should be stopped immediately, the vehicle can continue to run and be damaged. There was a problem of expanding. Therefore, there has been a demand for a technique that allows a user to grasp the details of an abnormality that has occurred in a vehicle.

It is a flowchart which shows the code analysis / transmission routine which the code analysis / transmission part of a crime prevention management center performs. It is a flowchart which shows the code analysis / transmission routine which the code analysis / transmission part of a crime prevention management center performs.

Hereinafter, an embodiment in which the present invention is embodied in a failure notification system for a two-wheel motorcycle will be described.
FIG. 1 is an overall configuration diagram showing a motorcycle failure notification system of the present embodiment.
The failure notification system of the motorcycle 1 (which may be referred to as a vehicle in the following description) of the present embodiment also has a function of preventing theft of the vehicle 1 in addition to a notification function of abnormal contents. Therefore, an ECU 3 (vehicle control means) mounted on the vehicle 1 is connected with a security module 4 (security control means, code reading / transmission means). These devices 3 and 4 and an external security management center 17 (management) In cooperation with the center), an abnormality notification function and a vehicle anti-theft function are provided.

  Since the ECU 3 is related to the traveling function of the motorcycle 1 like the control of the engine which is a power source for traveling, the ECU 3 is provided as standard equipment. On the other hand, the security module 4 is an optional device because it is a device for preventing theft, and only the user who wants the anti-theft function selects the security module 4 as an option when purchasing the motorcycle 1. In addition, a user who does not need the anti-theft function purchases the motorcycle 1 without the security module 4. However, if the user wants the anti-theft function in the process of use, the user can purchase the security module 4 alone and add it to his / her motorcycle 1. Can be equipped.

  For this reason, the ECU 3 performs the function of the original motorcycle 1 (in a normal mode described later) in the specification without the security module 4, and cooperates with the security module 4 in addition to the function of the motorcycle 1 in the specification with the security module 4. The anti-theft function (by a security mode described later) is provided.

  In addition, as a measure for preventing unauthorized replacement of the ECU 3 and the security module 4 for the purpose of theft of the vehicle 1, a unique ID is assigned to the ECU 3 and the security module 4 in advance. Then, when the ECU 3 and the security module 4 are electrically connected, the respective IDs are associated with each other. After each engine start, the respective IDs are collated, and then the ECU 3 starts the engine on condition that the IDs match. It is supposed to run. When the security module 4 is selected as an option at the time of purchase, the initial electrical connection is the time when the ECU 3 and the security module 4 are connected and powered on in the vehicle 1 assembly process. When the security module 4 is additionally installed in the process, it is a time when the user connects the security module 4 to the ECU 3 and turns on the power.

Hereinafter, specific configurations of the ECU 3 and the security module 4 will be described with reference to FIG.
The ECU 3 includes an ID authentication unit 6, a mode switching unit 7, and a startability determination unit 8. The ID authenticating unit 6 is given a unique ID on the ECU 3 side as described above and has a function of collating its own ID with the ID on the security module 4 side. The mode switching unit 7 selectively selects one of a normal mode that executes only the traveling function of the motorcycle 1 and a security mode that executes the anti-theft function in cooperation with the security module 4 in addition to the traveling function. Run. The startability determination unit 8 has a function of determining permission or prohibition of engine start based on the ID collation result when starting the engine in the crime prevention mode, and is mounted on the vehicle 1 only when the permission determination is made. The engine starting device 9 is operated to start the engine.

  When the vehicle 1 is not equipped with the security module 4 (a state where the security module 4 is not electrically connected to the ECU 3), the mode switching unit 7 of the ECU 3 is switched to the normal mode side, and the start possibility determination unit 8 It is switched to the permission side, and this switching state is maintained. For this reason, the ECU 3 executes only the traveling function of the motorcycle 1 based on the normal mode, and operates the engine starter 9 unconditionally without performing ID collation with the security module 4 side when the engine is started. Thereby, although the motorcycle 1 does not have an anti-theft function, it can run by starting the engine as usual.

On the other hand, the security module 4 includes an ID authentication unit 10, a theft sensor 11 (vehicle behavior detection means) and a theft determination unit 13 (security control means) provided with a vibration sensor 12 (vehicle behavior detection means), a GPS reception unit 14 (vehicle). Behavior detecting means) and 3G and 4G communication section 15 (communication means). The ID authentication unit 10 is given a unique ID on the security module 4 side in advance, and has a function of collating its own ID with the ID on the ECU 3 side. The theft determination unit 13 determines the presence or absence of the vehicle 1 in cooperation with the crime prevention management center 17 and executes a theft deterrence process for avoiding the removal of the vehicle 1 when the theft occurs.
The GPS receiver 14 receives position information data from a GPS satellite by a GPS antenna (not shown), calculates and acquires the position (latitude, longitude, altitude, etc.) of the own vehicle based on the position information data, and the theft determination unit 13. And output to the 3G and 4G communication unit 15.

  The 3G, 4G communication unit 15 has a function of exchanging information with the crime prevention management center 17 through a mobile phone line (communication line) such as 3G, 4G. Although details will be described later, the vehicle position information acquired by the GPS receiving unit 14, the detection information of the inclination sensor 11 and the vibration sensor 12 and the like are transmitted to the crime prevention management center 17, and the vehicle theft from the crime prevention management center 17 The 3G and 4G communication unit 15 executes reception processing such as a determination result of whether or not there is any time.

The crime prevention management center 17 is a base station installed in a predetermined area to prevent theft of a large number of vehicles 1 registered in advance, and determines whether there is a vehicle theft through a mobile phone line, notifies the user of the vehicle theft, etc. I do.
The ID registration unit 18 of the security management center 17 registers the IDs of the ECUs 3 and the security modules 4 of the vehicles 1 and the IDs of the users of the vehicles 1 (in the figure, the ID of a single vehicle is registered). Show). The security management center 17 is provided with a theft determination unit 19 (security control means) for determining whether the vehicle is stolen. The theft determination unit 19 is provided in the security module 4 of each vehicle 1. The same function as the theft determination unit 13 is performed, and the theft deterrence process is executed in preference to the theft determination unit 13 on the crime prevention module 4 side as will be described later.

Since the IDs of the ECU 3, the security module 4, and the user are registered in the ID registration unit 18 of the security management center 17 as described above, the registration procedure is described first.
When the ECU 3 side and the security module 4 are electrically connected by additional equipment in the assembly process of the vehicle 1 or in the process of use by the user, the ID authentication units 6 and 10 on the ECU 3 side and the security module 4 side mutually assign IDs. Exchange and register the other party's ID with their own ID. After completing the ID registration, the user is encouraged to register the ID in the crime prevention management center 17, and the user uses the mobile phone in response to the vehicle information (for example, the chassis number) and the self-identification. Is sent to the crime prevention management center 17. The ID registration unit 18 of the crime prevention management center 17 registers the user ID together with the vehicle information and the mail address. The ID of the user at this time may be determined unilaterally by the crime prevention management center 17, or the user may set a favorite ID.

  When the user ID registration is completed, the crime prevention management center 17 specifies the vehicle 1 from the vehicle information and transmits an ID notification request to the vehicle 1. The ID notification request is received by the 3G and 4G communication unit 15 of the security module 4 on the vehicle 1 side and is input to the ID authentication units 6 and 10 of the ECU 3 and the security module 4. Each ID authentication unit 6, 10 returns its own ID to the crime prevention management center 17 via the 3G, 4G communication unit 15, and those IDs are registered in the state linked to the IDs of already registered users. Registered in the unit 18.

  Thereby, the theft determination unit 19 of the security management center 17 can recognize the correspondence between the IDs of the ECU 3 and the security module 4 mounted on the vehicle 1 and the ID of the user who owns the vehicle 1. When the corresponding vehicle 1 is stolen, e-mail notification to the user of the vehicle 1 becomes possible.

  When the ID registration at the security management center 17 is completed as described above, a security mode switching command is transmitted from the security management center 17 to the vehicle 1. The security mode switching command received via the 3G and 4G communication unit 15 is input to the theft determination unit 13 of the security module 4 and to the mode switching unit 7 of the ECU 3.

  Then, the theft determination unit 13 starts to operate based on the crime prevention mode switching command, the mode switching unit 7 is switched from the normal mode to the crime prevention mode, and the start possibility determination unit 8 is switched based on the ID collation result. . Therefore, the vehicle 1 has an anti-theft function based on the crime prevention mode. Specifically, the anti-theft processing is started by the anti-theft determination unit 13 and the start possibility determination unit 8 based on the ID collation result at the time of starting the engine. When it is considered that the ECU 3 or the security module 4 is illegally exchanged, the engine start is prohibited.

First, engine start prohibition processing based on ID verification will be described.
In the security mode, the ID authentication unit 6 on the ECU 3 side checks the ID input from the ID authentication unit 10 on the security module 4 side every time the engine is started, and if the IDs match, When the ID match information is output to the startability determination unit 8 and the ID does not match or when the ID is not input from the security module 4 side (hereinafter expressed as a case where the ID does not match including all of them) The ID mismatch information is output to the startability determination unit 8.

  Similarly, after the ID is linked, the ID authentication unit 10 on the crime prevention module 4 side also compares the ID input from the ID authentication unit 6 on the ECU 3 side with the registered ID on the other side every time the engine is started. If the IDs do not match, the ID mismatch information is output to the startability determination unit 8.

  Here, in order for both the ID authentication units 6 and 10 on the ECU 3 side and the security module 4 side to determine the ID match as described above, each is a legitimate device and is normally attached to the vehicle 1 and is mutually connected. It is necessary to be connected by electrical wiring (K-Line 25 described later). If either the ECU 3 or the security module 4 is illegally exchanged, the ID is entered from the other party, but it is not a regular ID, so the ID does not match, and any of the devices 3 and 4 are removed, the electrical wiring is disconnected, etc. In this case, since ID is not input from the other party, ID collation itself is impossible (hereinafter, all of these cases are expressed as illegal exchange etc.).

  The startability determination unit 8 of the ECU 3 is switched to the permitting side on condition that the ID match information is input from the ID authentication units 6 and 10 of both the ECU 3 and the security module 4. In other cases (when either one or both are ID mismatch information), the start permission determination unit 8 is switched to the prohibition side, and the engine start is thereby prohibited. In such a case, it can be considered that an unauthorized exchange or the like of either the ECU 3 or the security module 4 has occurred. Therefore, by prohibiting engine start, it is possible to prevent vehicle theft from being carried away by the motorcycle 1 being driven by an unauthorized person.

Next, the theft deterrence process executed in the crime prevention mode will be described. In the present embodiment, since the determination process is performed in addition to the control on the vehicle 1 side as well as the determination process at the crime prevention management center 17, the details will be described below.
First, in a situation where communication is possible between the vehicle 1 side and the crime prevention management center 17, the theft deterrence processing is executed by the theft determination unit 19 on the crime prevention management center 17 in preference to the theft determination unit 13 on the crime prevention module 4 side. The

  Therefore, various kinds of information necessary for the theft deterrence process are transmitted periodically (for example, every 5 minutes) from the vehicle 1 side to the crime prevention management center 17 side. Specifically, in the security module 4 on the vehicle 1 side, detection information of the inclination sensor 11 and the vibration sensor 12 is input to the 3G and 4G communication unit 15, and the vehicle position information acquired by the GPS reception unit 14 is 3G. , 4G communication unit 15 and the information is transmitted to the security management center 17 side through the 3G, 4G communication unit 15 together with the IDs of the ECU 3 and the security module 4.

  The theft determination unit 19 of the crime prevention management center 17 specifies the vehicle 1 based on the received ID, and then executes a theft suppression process based on the sensor detection information and the vehicle position information. First, it is determined whether the vehicle 1 has been stolen. For example, when the motorcycle 1 parked with the engine stopped is loaded on a truck or the like and taken away, the inclination of the motorcycle 1 changes when loaded on the truck, and the traveling vibration reaches the motorcycle 1 during transportation by the truck. In addition, although the engine is stopped, the position of the host vehicle changes due to transportation on the truck. For this reason, when the change in the inclination angle is detected by the inclination sensor 11, the traveling vibration is detected by the vibration sensor 12, or the own vehicle position changes based on the own vehicle position information, the unauthorized motorcycle 1 is transported. Is considered. If there is no sign suggesting theft, the theft determination unit 19 waits until information from the next vehicle 1 is received.

  When there is any sign of theft, the theft determination unit 19 makes a provisional determination indicating the possibility of theft. At this time, the user ID corresponding to the ID received from the vehicle 1 side is read from the ID registration unit 18 by the theft determination unit 19 and a theft confirmation email is transmitted to the user's email address. The user who received the theft confirmation e-mail judges whether or not the behavior of the corresponding vehicle 1 is recognized (whether or not he / she did it), and if so, returns a response-free e-mail. To do. If it is not recognized, a response mail is sent back, and a report to the police is taken.

The theft determination unit 19 cancels the provisional determination that the theft has occurred when receiving a countermeasure-unnecessary mail, and waits for information reception from the next vehicle 1 side. At the time of receiving the countermeasure necessary mail, the temporary determination is switched to the main determination having the meaning of theft confirmation, and an abnormality notification command is transmitted to the vehicle 1 side. The abnormality notification command is input to the theft determination unit 13 via the 3G and 4G communication unit 15 of the security module 4, and the horn 20 a and the headlight 20 b of the motorcycle 1 are operated by the theft determination unit 13. As a result, abnormalities are reported to the surroundings, and the motivation of the fraudster is cut off, which leads to theft deterrence.
In parallel with such abnormality notification processing, for example, the vehicle speed of the stolen vehicle may be limited by a decrease in engine output, or restart may be prohibited while the engine is stopped.

  On the other hand, in a situation where communication between the vehicle 1 side and the crime prevention management center 17 is interrupted, the anti-theft processing is executed by the theft determination unit 13 of the crime prevention module 4 on the vehicle 1 side instead of the theft determination unit 19 on the crime prevention management center 17 side. Is done. Therefore, when it is determined that the theft has occurred based on inclination change, vibration detection, or own vehicle position information, the theft determination unit 13 appropriately notifies the surroundings using the horn 20a or the headlight 20b.

  Further, when the vehicle 1 is taken away in front of the user, an abnormality notification command is transmitted from the theft determination unit 19 to the vehicle 1 side based on the vehicle theft notification from the user side to the crime prevention management center 17. . Therefore, in this case as well, processing is executed on the vehicle 1 side in the same manner as described above, and vehicle theft is suppressed.

Next, the abnormality notification function provided in the failure notification system of the present embodiment will be described.
FIG. 2 is a conceptual diagram showing the relationship between reading and transmission of a fault code between the ECU 3 and the security module 4.
The microcomputer 21 in the figure functions as the ID authentication unit 10 and the theft determination unit 13 described with reference to FIG. 1, and also serves as a code reading / transmitting unit 22 (code reading / transmitting unit) that reads and transmits a fault code. Function. The microcomputer 21 is connected to the ECU 3 via a K-Line 25 as an interface, and a failure indicator warning lamp 26 provided on the instrument panel of the vehicle 1 is connected to the ECU 3. When an abnormality occurs in various functional components mounted on the vehicle 1, an OBD failure code is stored in the ECU 3.

When the ignition switch of the vehicle 1 is turned on, the code reading / transmission unit 22 executes the failure code reading / transmission routine shown in FIG. 3 at a predetermined control interval.
First, in step S1, a failure code is read from the ECU 3 via the K-Line, and in the subsequent step S2, it is determined whether there is a failure code (whether it has been read). If the determination is No (No), the warning lamp 26 is turned off in Step S3. If the determination is Yes (Yes), 3G and 4G communication is performed in Step S4 together with the failure code (information on the failure code) together with the IDs of the ECU 3 and the security module 4. The data is transmitted to the crime prevention management center 17 through the mobile phone line by the unit 15, and after the warning lamp 26 is turned on in the subsequent step S5, the routine is terminated.

On the other hand, the security management center 17 is provided with a code analysis / transmission unit 23 (code analysis / transmission means) as shown in FIG. The analysis / transmission unit 23 can also arbitrarily refer to the registration contents of the ID registration unit 18.
4 and 5 are flowcharts showing a code analysis / transmission routine executed by the code analysis / transmission unit 23. The code analysis / transmission unit 23 executes the routine at a predetermined control interval.

  First, in step S11, it is determined whether a failure code has been received from the vehicle 1 side. When the determination is No, the routine is temporarily terminated. If the determination of Yes is made in step S11, the failure code is analyzed in step S12, and the abnormality content corresponding to the failure code is specified. In the following step S13, it is determined whether or not the abnormal content is a momentary disconnection of the electric system. If No, the process proceeds to step S14, where the abnormal content is detected by a throttle position sensor (TPS) that detects the opening of the throttle valve of the engine. It is determined whether or not there is a failure.

  When the determination in step S14 is No, the process proceeds to step S15, where it is determined whether or not the abnormal content is a failure of the bypass air valve for adjusting the intake air amount. When the determination is No, the process proceeds to step S16 and the abnormal content is determined. It is determined whether or not the injector for fuel injection of the engine has failed. If No, the process proceeds to step S17, where it is determined whether or not the abnormality is a failure of the fuel pump that pumps fuel to the injector. If No, the routine is temporarily terminated.

  Further, when the determination in step S13 is Yes, in step S18, “there is frequent occurrence of instantaneous disconnection in the XX portion” is determined as the abnormality content, and in the subsequent step S19, as a countermeasure to be taken by the driver for this instantaneous disconnection, “ Create a message "Run with caution because there is a risk of affecting driving." In this case, since it is a minor abnormality that allows the vehicle 1 to continue traveling, “stage 1” is determined as the severity of the abnormality content in step S20. In the subsequent step S21, after identifying the user of the vehicle 1 based on the IDs of the ECU 3 and the security module 4 received together with the failure code, the user is notified of the abnormal content, a message indicating the action to be taken by the driver, and the content of the abnormal content. Send severity as reference information. The form of transmission to the user may be mail or synthesized speech.

  If the determination in step S14 is Yes, “TPS failure” is determined as the abnormality content in step S22, and in the subsequent step S19, a message “Vehicle speed limited” is taken as a countermeasure to be taken by the driver for this TPS failure. Create In this case, since the abnormality is not so severe that the vehicle 1 is stopped, “stage 2” is determined as the severity of the abnormality content in step S24, and transmission to the user is performed in subsequent step S21.

  If the determination in step S15 is Yes, “air valve failure” is confirmed as the abnormality content in step S25, and in the subsequent step S26, a message “engine difficult to start” is displayed as a countermeasure to be taken by the driver for the air valve failure. Create In this case as well, since the abnormality is not so great that the vehicle 1 is stopped, “stage 2” is determined as the severity of the abnormality in step S27, and transmission to the user is performed in subsequent step S21.

  When the determination in step S16 is Yes, in step S28, “injector failure” is confirmed as the abnormality content, and in the subsequent step S29, a message “engine cannot be started” is taken as a countermeasure to be taken by the driver for this injector failure. Create In this case, since the vehicle 1 cannot travel, “stage 3” is determined as the severity of the abnormality content in step S30, and transmission to the user is performed in subsequent step S21.

  Further, when the determination in step S17 is Yes, “fuel pump failure” is confirmed as the abnormality content in step S31, and in the subsequent step S32, “engine cannot be started” as a countermeasure to be taken by the driver for this fuel pump failure. Create a message for In this case as well, since the vehicle 1 cannot travel, “stage 3” is determined as the severity of the abnormality content in step S33, and transmission to the user is performed in subsequent step S21.

  The user who has received the above reference information grasps the abnormality content actually occurring in the vehicle 1, further grasps what action should be taken from the message for dealing with the abnormality content, and combines them. Also grasp the severity of the abnormal content. Therefore, for example, when an electrical disconnection occurs, the vehicle 1 is caused to travel with care for repair at a sales dealer. When the TPS fails, the vehicle 1 is caused to travel to a sales dealer while avoiding excessive acceleration in accordance with a message that the vehicle speed is limited.

  Also, when the bypass air valve fails, the engine is stopped during the travel to the sales dealer according to the message that the engine is difficult to start. Further, when the injector or fuel pump fails, according to a message indicating that the engine cannot be started, the vehicle dealer is requested to convey the vehicle 1 in advance of the continuation of excessive engine start.

  As described above, in the failure notification system for the motorcycle 1 according to the present embodiment, the failure code stored in the ECU 3 is read and transmitted to the crime prevention management center 17 when an abnormality occurs in various functional parts mounted on the vehicle 1. The abnormality content obtained by analyzing the code, the message of the countermeasure to be taken by the driver, and the severity of the abnormality content are transmitted from the crime prevention management center 17 to the user. Therefore, the user can grasp the content of the abnormality accurately and easily, and can execute an optimum countermeasure. Thus, for example, in the case of a minor abnormality that allows the vehicle 1 to continue to travel, the vehicle 1 can continue to travel with peace of mind. It is possible to prevent a situation in which the damage of the device is expanded.

  On the other hand, as described above, the failure notification system of the present embodiment also has a theft prevention function of the vehicle 1 in addition to the abnormality notification function. The crime prevention module 4 functions as both a code reading / transmission unit that reads and transmits a fault code from the ECU 3 and a crime prevention control unit that transmits sensor information and own vehicle position information, and each transmission. By using the 3G and 4G communication unit 15, the communication means is shared. Therefore, the structure of the security module 4 can be simplified and the manufacturing cost can be reduced.

This is the end of the description of the embodiment, but the aspect of the present invention is not limited to this embodiment. For example, in the above embodiment, the failure notification system of the two-wheeled motorcycle 1 is embodied, but the present invention is not limited to this. For example, when a general-purpose engine used for a three-wheeled motorcycle or a ship or a generator is mounted on a golf cart, a snowplow, or the like, the failure notification system for these engines may be embodied. Good.
In the above embodiment, the vehicle 1 has a theft prevention function in addition to the abnormality content notification function. However, a failure notification system having only the abnormality content notification function may be used.

Moreover, in the said embodiment, although ECU3 and the security module 4 were made into a different body, you may add the function of the security module 4 to ECU3. Specifically, the code reading / transmitting unit 22 and the 3G and 4G communication unit 15 may be built in the ECU 3 itself.
In the above-described embodiment, the occurrence of abnormality is dealt with as a functional component for operating the engine, such as an instantaneous disconnection of an electric system, a throttle position sensor, a bypass air valve, an injector, and a fuel pump.
