The engine ECU determines, for example, a fuel injection amount by the engine, based on data acquired by various sensors provided in the vehicle.

  More specifically, the engine ECU adjusts the fuel injection amount. However, in order to accurately adjust the air-fuel ratio of the fuel, it is necessary to detect the intake air amount sucked by the engine. Therefore, an intake air amount detection sensor for detecting the intake air amount is arranged in the middle of the intake device, and the fuel injection amount is adjusted based on the air amount acquired by the intake air amount detection sensor.

Therefore, the cooling temperature of the cooling water is detected in advance by a water temperature sensor provided in a cooling device that cools the engine. The fuel concentration is adjusted in accordance with the cooling temperature obtained in (1).

  That is, as described above, the engine ECU has a function of adjusting the fuel injection amount, the fuel concentration, and the like, and the fuel injection amount and the fuel concentration once controlled are stored in the storage unit ( For example, control data in which an optimal control result is obtained is stored as reference control data (learned value). Thereafter, based on the reference control data, the fuel injection amount, the fuel concentration, and the like are controlled. As a result, the engine is efficiently controlled.

  Here, as described above, in order to utilize the vehicle state (for example, fuel injection amount control data) acquired by the host vehicle, an abnormal situation (failure situation) related to various sensors or internal combustion engines arranged in the vehicle is displayed. A vehicle diagnostic device is installed that displays a warning (diagnostic code display) by lighting / flashing an indicator that an abnormality has occurred by making a diagnosis.

  A vehicle diagnostic apparatus mounted on such a vehicle monitors the output of a sensor provided in the vehicle, and if the output value (level) of the sensor exceeds a preset threshold, a failure corresponding to the failure content A function of displaying a code (diag code) on an indicator is provided, and a driver can know a vehicle failure state or the like by self-diagnosis displayed on the indicator (see Patent Document 1).

By determining whether or not there is a change based on the acquired reference control data (learned value), whether there is any abnormal state inside the vehicle at the present time, or whether there is a tendency of abnormal state or failure (abnormality to the vehicle) A function of determining whether or not a state has occurred or a possibility of occurrence of an abnormal state).

  Specifically, the vehicle is compared to the vehicle 100 and the other vehicles 101 to 103 that are determined to have an abnormal state of the vehicle or a possibility (trend) of failure based on the fluctuation or change rate of the reference control data. Warnings that indicate an abnormal state or an abnormal state or the possibility of a failure (for example, “Vehicle is currently in an abnormal state”, “An abnormal state has occurred. Etc.) etc.) is provided through communication.

  Further, the vehicle management center 200 detects the occurrence of an abnormal state or the tendency of occurrence of an abnormal state in a vehicle type that is determined to have an abnormal state even when the possibility of the abnormal state is not determined for each individual vehicle itself. In such a case, a function for notifying a vehicle corresponding to a vehicle type in which an abnormal state may occur is provided.

  Specifically, in the case of vehicles of the same vehicle type, because the configuration and performance of the engine and equipment are the same, the durability of these equipment is almost the same, so the abnormal state and failure occurrence status is also almost the same. It may be the same time. From this, the vehicle management center 200 targets other vehicles having the same vehicle type as that of the vehicle type that has been determined to have the possibility of occurrence of an abnormal state or failure, with respect to this other vehicle. In addition, a request notification of reference control data is transmitted, an abnormal state or failure occurrence is predicted in advance, and an alarm indicating that an abnormal state or failure occurrence is suggested to a vehicle corresponding to the vehicle type in advance. ing. In this case, an upper limit value of the number of occurrences of abnormal conditions in the same vehicle type is set, and when this upper limit value is reached, it is used as a reference for predicting the occurrence of an abnormal condition in the same vehicle type.

  As shown in FIG. 3, the vehicle management center 200 includes a vehicle control data acquisition unit 210, standard control data setting tables 210a and 210b, a vehicle control data storage unit 220, a vehicle control data storage table 221, and a vehicle state determination. Unit 230, vehicle state determination table 231, vehicle type management table 232, vehicle state analysis unit 240, and abnormal state notification unit 250.

  The vehicle control data acquisition unit 210 has a function of acquiring reference control data related to engine control transmitted from the vehicle 100 and the other vehicles 101 to 103. As described above, in the case of this example, the intake air amount and the fuel injection amount related to the engine are acquired as the numerical values of the reference control data.

  The vehicle control data storage unit 220 has a function of storing a plurality of reference control data (learned values) by the vehicle 100 and the other vehicles 101 to 103 acquired by the vehicle control data acquisition unit 210. Further, as shown in FIG. 6, the vehicle control data storage table 221 stores the control data of the vehicle 100 and the other vehicles 101 to 103 with the vehicle management number (XXX123, XXX429,...) And the vehicle type. This is a table stored in association with (vehicle type A, vehicle type B...).

(Configuration of standard control data setting table 210a)
Next, details of the configuration contents of the standard control data setting table 210a will be described with reference to FIG. As shown in FIG. 4, in the standard control data setting table 210a, control data that is optimal for engine control by each electronic control computer (in this example, the engine ECU 190) is set as standard control data (reference learning values). . That is, when control is performed by engine ECU 190, engine 195 can be started and run well if control is performed using the standard control data (reference learning value) set in standard control data setting table 210a. .

  More specifically, the numerical data “20 to 70 (cc / min)” of the fuel injection amount when the engine ECU 190 (FIG. 1) controls each air intake amount “100, 150, 200”. And a table in which standard control data (reference learning value) corrected so that the control result is optimized is stored.

  For example, in this standard control data setting table 210a, it is assumed that “fuel injection amount 25 (cc / min)” is the optimum fuel injection amount among the fuel injection amounts 20, 25, and 35 when the intake air amount is 100. In this case, the “fuel injection amount 25 (cc / min)” is set as the standard control data (reference learning value). In the case of the intake air amount 150, the standard fuel injection amount is “fuel injection amount 48 (cc / min)”. min) ”indicates that the standard fuel injection amount is set as“ fuel injection amount 65 (cc / min) ”in the case of the intake air amount 200.

(Configuration of standard control data setting table 210b)
Next, with reference to FIG. 5, the details of the configuration and functions of the standard control data setting table 210b corresponding to the engine state (engine speed) of the vehicle 100 will be described. The standard control data setting table 210b shown in FIG. 5 stores standard control data (reference learning value) when the engine state (engine speed / running state) in the vehicle 100 is controlled by the engine ECU 190. It is a table.

  In other words, in this example, the control data and the optimum controlled according to the engine state (engine speed / running speed) of five (during idling, starting, running at low speed, running at medium speed, and running at high speed). This is a table in which standard control data (reference learning value) set as the fuel injection amount is stored / set. As shown in the figure, for example, a fuel injection amount 24 (cc / min) is set as optimum standard control data (reference learning value) during low-speed traveling.

  That is, when the engine ECU 190 performs control according to each engine state (for example, at idle, at start-up, at low speed, at medium speed, at high speed), it is set in this standard control data setting table 210a. By performing control based on the standard control data (reference learning value), it is possible to satisfactorily perform engine control corresponding to each engine state. Specifically, it is possible to perform engine control without causing problems such as engine stall and knocking.

  As shown in the figure, according to this standard control data setting table 210b, the standard fuel injection amount is 8 (cc / min) when the vehicle 100 is idling, and the fuel injection amount is 15 (cc / min) at the start. The standard fuel injection amount is 24 (cc / min) during low-speed driving, the standard fuel injection amount is 31 (cc / min) during low-speed driving, and the standard fuel injection amount during high-speed driving. Each indicates that the amount is 41 (cc / min).

  Returning to FIG. 3, the vehicle state determination unit 230 determines that the vehicle is in an abnormal state at the present time based on the reference control data (learned value) by the vehicle 100 and the other vehicles 101 to 103 acquired from the vehicle control data acquisition unit 210. It has a function of determining whether or not there is a possibility of failure, and is stored in the reference control data (learned value) acquired for each vehicle and in the vehicle state determination table 231 (FIG. 7) in advance. It has a function of comparing the reference control data as a standard and determining whether the control contents of the two match.

  Specifically, when the reference control data transmitted from the vehicle 100 is numerical data that substantially matches the standard control data, it can be determined that there is no problem with the vehicle 100 and the standard control data (reference If the control data is not the same as the (learned value), but the control data is approximate, there is no problem at the present time, but it can be determined that a failure or abnormal condition may occur later, which is significantly different from the standard control data. In the case of numerical data, it can be determined that an abnormality has occurred in the vehicle 100 at the present time. In addition, instead of simply comparing the numerical values of both control data, fluctuations and change rates can be calculated, and the tendency of the abnormality occurrence state of the vehicle 100 can be determined according to the calculated change rates.

  Further, when it is determined that the vehicle has an abnormality, the vehicle state determination unit 230 determines whether the occurrence of the abnormal state is an abnormal phenomenon of the vehicle alone or an abnormal phenomenon that occurs in common with the vehicle type of the vehicle. It has a function to judge. And the determination result of the vehicle state determined by this vehicle state determination part 230 is stored in the vehicle type management table 232 (FIG. 8).

  The vehicle type management table 232 is a table that stores a vehicle management number, a vehicle type, and a vehicle state determination result of each vehicle in association with each vehicle. That is, the vehicle type management table 232 (FIG. 8) is automatically created based on the vehicle state determination table 231. The vehicle type management table 232 is a table in which vehicle determination results are stored in association with vehicle types in the plurality of vehicles 100 and the other vehicles 101 to 103.

  As will be described later, the vehicle type management table 232 comprehensively determines the vehicle state for each vehicle type, so that the abnormal state with respect to the vehicle in advance is targeted for the vehicle type of the vehicle for which the abnormal state is determined and the corresponding vehicle. Or an alarm indicating that there is a tendency to generate an abnormal state.

  The vehicle state analysis unit 240 causes the occurrence of the abnormal state (possibility of the abnormal state) as a phenomenon of the vehicle 100 alone with respect to the abnormal state determined by the vehicle state determination unit 230 or the possibility of occurrence of the abnormal state. It is equipped with a function to analyze whether it is an abnormal phenomenon that occurs in the same entire vehicle model. In the analysis by the vehicle state analysis unit 240, for example, when the number of abnormal state determinations is set to a predetermined numerical value (reference value) and the set reference value is exceeded, the vehicle type is not determined as an independent vehicle determination but the vehicle type is targeted. Car type abnormal state determination processing is performed.

  Based on the analysis result analyzed by the vehicle state analysis unit 240, the abnormal state notification unit 250 may generate an abnormal state or generate an abnormal state with respect to a single vehicle or a vehicle having a plurality of vehicle types. It is equipped with a function for notifying an alarm indicating that there is a possibility.

  The communication I / F unit 260 has a function of performing communication between the communication I / F unit 166 included in the vehicle 100 and the other vehicles 101 to 103 and the communication I / F unit 301 included in the dealer 300. I have.

(Vehicle condition analysis procedure)
Next, the processing operation of the vehicle state analysis procedure will be described in detail with reference to FIG. In the flowchart shown in FIG. 9, an engine ECU 190 (FIG. 1) that generally controls the engine 195 will be described as an example of an electronic control computer (ECU) provided in the vehicle.

  That is, as shown in the flowchart of FIG. 9, it is first determined whether there is any control by the engine ECU 190 (FIG. 1) provided in the vehicle 100 (step S100), and the control by the engine ECU 190 is activated. If determined (Yes at step S100), arbitrary reference control data (learned value) by the engine ECU 190 is acquired (step S150), and then the reference control data (learned value) acquired at step S150 is stored (step S150). Step S200). Note that the reference control data (learned value) acquired in step S150 is stored in the engine control data storage unit 164 (FIG. 1).

  Here, the processing from step S100 to step S200 will be described in detail. If the control by the engine ECU 190 is control related to the fuel injection amount, the intake air amount detection sensor 183 (FIG. 1) in the processing of step S150. The fuel injection amount controlled by the engine ECU 190 (corrected so that the control result is optimized) based on the intake air amount acquired in step (in this example, the intake air amount is 100). Reference control data (learned value) ") is acquired. As described above, the detection data related to the engine acquired by the intake air amount detection sensor 183 is acquired by the engine state acquisition unit 163 (FIG. 1).

  Hereinafter, in the example of this flowchart, in order to specifically describe this processing procedure, the engine ECU at this time is controlled by 190 (FIG. 1) according to the intake air amount 100 acquired in step S150. A description will be given assuming that the fuel injection amount is 35 (cc / min).

  In this flowchart, only control of the fuel injection amount related to the engine 195 (FIG. 1) is described as an example of this processing procedure. However, in this case, not only the fuel injection amount but also the fuel injection pressure and the fuel injection amount are described. The reference control data (learned value) may be subdivided into data by acquiring the time and the like.

  Next, the traveling environment state of the traveling vehicle is acquired (step S250). The travel environment acquisition process in step S250 is performed by acquiring the road surface condition in the vicinity of the host vehicle by the VISP processing unit 175 based on the weather information acquired by the VISP receiver 171 by the navigation device 170 (FIG. 2). Environmental data (wet conditions on the road surface when it rains) can be acquired.

  Hereinafter, the vehicle 100 transmits to the vehicle management center 200 the reference control data (learned value) related to the engine control acquired in step S150 and the travel environment data related to the travel environment of the vehicle acquired in step S250. (Step S300). At this time, the reference control data (learned value) transmitted from the vehicle to the vehicle management center 200 and the vehicle environment data, as well as the vehicle management numbers (XXX123, XXX363123,...) For specifying the vehicle are also used. Sent to.

  Here, as described above, the engine state acquisition unit 163 that acquires the engine state includes a plurality of engine states including idling, engine start, low speed driving, medium speed driving, and high speed driving. Since it has a function to acquire by dividing into patterns, the reference control data (learned value) is not set as single data (fuel injection amount), but in multiple engine states (idle, engine start, low speed) A plurality of reference control data (learned values) corresponding to traveling, medium-speed traveling, and high-speed traveling) is acquired, and the acquired reference control data (learned value) is transmitted to the vehicle management center 200. Good.

  On the other hand, when the vehicle management center 200 receives the transmission data reference control data (learned value, travel environment data, vehicle management number) transmitted from the vehicle 100 (Yes at step S310), first, the vehicle management number (XX of the vehicle). X123, xxx363 ...) (step S311), and then reference control data related to engine control and vehicle running environment data that is the surrounding environment of the vehicle (such as a wet state of the road surface) are obtained (step S312). ), The process proceeds to a vehicle state determination process for determining the vehicle state based on the received reference control data and vehicle travel environment data (step S313).

  As described above, this vehicle state determination process is performed by referring to the vehicle state determination table 231 (FIG. 7) provided in the vehicle management center 200 and the standard control data (reference learning value) registered as the optimal standard control data. ) And reference control data (learned value) transmitted from the vehicle 100 side.

  Specifically, it is determined whether the reference control data (learned value) transmitted from the vehicle matches the standard control data (step S314), and the reference control data (learned value) is determined by the determination in step S314. And the standard control data (reference learning value) do not match (reference control data ≠ standard control data) (No in step S314), the abnormal condition notification signal indicating the occurrence of an abnormal condition with respect to the vehicle 100 Is notified (step S315). This abnormal state notification signal indicates an alarm for notifying the occurrence of an abnormal state or the occurrence tendency of the abnormal state in the vehicle 100.

  Specifically, referring to the vehicle state determination table 231 in FIG. 7, as shown in the vehicle state determination table 231, the fuel injection amount (standard control data) when the intake air amount is 100 is 25 ( As described above, the reference control data (learned value) transmitted from the vehicle is 35 (cc / min). Therefore, the reference control data (learned value) is a numerical value of 35 cc / min. Since min deviates from the standard control data (25 cc / min) and the two control data are different (35 cc / min ≠ 25 cc / min), in this example, the vehicle state is determined to be an abnormal state. The vehicle (vehicle management number: XXX123) that has transmitted the analysis state of the vehicle this time is a notification target of the abnormal state notification.

  That is, an alarm indicating that an abnormal state has occurred (for example, “An abnormal state has occurred. Check / repair with a dealer) for the vehicle to be notified (vehicle management number: XXX123). Please go. ")

  Here, in this example, if the numerical values of both control data do not match, it is determined that an abnormal state has occurred, and the alarm is to be notified, but even if the numerical values of the control data do not match, both If the numerical value of the control data is an approximate value, the fluctuation or change rate of the control data is calculated, and the vehicle is not in an abnormal state at this time, but an abnormality may occur. A notification to that effect (abnormal state prediction notification) may be performed as a notification.

  On the other hand, when the vehicle receives the abnormal state notification signal transmitted from the vehicle management center 200 (Yes at step S350), the vehicle determines that the vehicle needs to be inspected / repaired by a repair shop or the like. A vehicle inspection / repair request request notification for requesting vehicle inspection / repair is transmitted (step S400). In the following, the vehicle will be inspected and repaired by the repair shop of the dealer 300 by communication from the dealer 300 or the like.

  Here, as shown in the flowchart of FIG. 9, in this example, after the vehicle state determination process is performed, a vehicle type abnormal state determination process for the vehicle type of the vehicle is then performed (step S316). This vehicle type abnormal state determination process is a determination process for the vehicle type of the vehicle that is determined to be abnormal by the vehicle state determination process in step S313. Specifically, the occurrence of the abnormal state is the vehicle. This is a process for determining whether it is a single abnormal phenomenon or an abnormal phenomenon that occurs in common with this vehicle type.

  In addition, even when the possibility of an abnormal state is not determined for each individual vehicle itself, if the occurrence of an abnormal state or the occurrence tendency of the abnormal state is detected in a vehicle type that is determined to have an abnormal state, the abnormal state is This is a process for notifying a warning corresponding to a vehicle type that may occur.

  That is, as shown in the flowchart of FIG. 9, the vehicle type (vehicle type A, vehicle type B,...) Of this vehicle is determined based on the vehicle management number (XXX123, XXX363123,...) Of the vehicle ( Step S317). And the determination result of the vehicle state by the other vehicle registered as the same vehicle type as the vehicle type determined by this step S317 is acquired (step S318).

  Specifically, the number of abnormal state determinations for the same vehicle type is acquired, and the vehicle state of the vehicle type is determined based on the determination result acquired in step S318. Is determined (step S319). If it is determined in step S319 that the number of abnormal state determinations is greater than or equal to the predetermined number (Yes in step S319), another vehicle having the same vehicle type as the vehicle type determined to have an abnormality. Is notified that an abnormal condition may occur (step S320).

  More specifically, when the vehicle type of the vehicle determined to be in an abnormal state is the vehicle type B, an alarm (abnormality or failure) is applied to other vehicles of the vehicle type B when the number of occurrences of the abnormal state due to the vehicle type B is large. Notification indicating that there is a possibility of the occurrence of occurrence).

  That is, with reference to the vehicle type management table 232 in FIG. 8, for example, when the upper limit value (predetermined number) of the number of abnormal state determinations is set to 4 or more, the number of times an abnormal state has occurred under this condition Therefore, the vehicle management center 200 notifies the vehicle management center 200 that there is a possibility that an abnormal state may occur for a plurality of vehicles of the vehicle type B (for example, “abnormal state”). Please check with your dealer. ”).

  As described above, according to the present invention, the reference control data (learned value) performed for the engine ECU 190, together with the travel environment data around the vehicle acquired by the navigation device 170, the vehicle management center 200 (FIG. 4), and the vehicle state determination unit 230 of the vehicle management center 200 determines the value of the reference control data (learned value) of the vehicle transmitted from the vehicle and the preset standard control data, and the determination Based on the change or change rate of the reference control data (learned value), the presence / absence of occurrence of an abnormal state for the vehicle or occurrence prediction of the abnormal state is determined, and an alarm is notified to the vehicle determined to be abnormal. Therefore, it is possible to accurately grasp the vehicle state (usage state) for each vehicle and determine the occurrence of an abnormal state.
