FIG. 3 is a diagram showing the registration information of the table 12a representing the failure diagnosis code output from the in-vehicle computer diagnosis device 32 and the failure content. FIG. 4 is a flowchart showing an operation processing procedure by the taximeter 1 in the embodiment of the present invention. FIGS. 5A and 5B are diagrams showing a meter screen 15a for notifying that a failure has occurred.

  A taximeter according to an embodiment of the present invention will be described with reference to the drawings. The taximeter of this embodiment is used for a taxi vehicle equipped with an in-vehicle computer diagnostic device.

  FIG. 1 is a block diagram illustrating a configuration of a taximeter 1 according to an embodiment of the present invention. The taximeter 1 includes a CPU 11, a ROM 12, a RAM 13, a card reader / writer (R / W) interface 14, a display 15, interfaces (I / F) 16, 17, 18, an RTC 19, and an operation unit 21.

  The CPU 11 (control unit) controls the entire taximeter 1. The ROM 12 stores an operation program executed by the CPU 11. The RAM 13 is used as a working memory, and records a failure diagnosis code, time, travel data, and the like which will be described later.

  The card reader R / W interface (I / F) 14 (connector) is detachably mounted with a memory card 31 (recording medium) that is carried by a crew member and that reads and writes data. The memory card 31 can be inserted into and removed from an office-side rear processing device (data processing device) that analyzes sales data and the like.

  The display 15 is composed of an LCD, and displays a taxi fare (travel fee), details of a failure that has occurred in the vehicle, etc. on the meter screen 15a (see FIG. 2).

  The interface (I / F) 16 (communication unit) communicates with the in-vehicle computer diagnosis device 32 (in-vehicle device), and inputs a failure diagnosis code output from the failure diagnosis connector of the in-vehicle computer diagnosis device 32. In this embodiment, an OBD (On-Board-Diagnostics) II system is used as an in-vehicle computer diagnostic device. The in-vehicle computer diagnostic device 32 is configured by an ECU (Electronic Control Unit) that executes a diagnostic program registered in advance, and various types of signals generated in the vehicle based on signals from various sensors installed in each part of the vehicle. The presence or absence of a failure is diagnosed, and the diagnosis result is output as a failure diagnosis code. Details of the failure diagnosis code will be described later.

  A GPS receiver 34 that acquires the current position of the taxi vehicle is connected to the I / F 17. An ETC on-vehicle device 35 is connected to the I / F 18. A speed signal indicating the speed of the vehicle detected by the vehicle speed sensor 36 is input to an input port inside the CPU 11. Further, a tariff state that is changed by pressing various buttons provided on the operation unit 21 is input.

  The RTC (clock IC) 19 measures the current time. The time counted by the RTC 19 is recorded in the RAM 13 together with the travel data representing the driving state of the vehicle.

  FIG. 2 is a view showing the appearance of the taximeter 1. A meter screen 15 a of the display 15 is arranged on the front face of the taxi meter 1. Various buttons such as an empty vehicle button 21a and a rent button 21b are arranged as an operation unit 21 around the meter screen 15a. Also, below the meter screen 15a, an insertion port 14a of the card R / W interface 14 into which the memory card 31 is detachably mounted is installed.

  FIG. 3 is a diagram showing the registration information of the table 12a representing the failure diagnosis code and the failure content output from the in-vehicle computer diagnosis device 32. This table 12 a is stored in the ROM 12. The failure diagnosis code indicates which part of the vehicle has a failure, and is composed of five-digit alphanumeric characters. For example, when the failure diagnosis code is “P01XX”, the failure content is “measurement of fuel and air”. When the failure diagnosis code is “P02XX”, the failure content is “adjustment of fuel and air”.

  The operation of the taximeter 1 having the above configuration will be described. FIG. 4 is a flowchart showing an operation processing procedure by the taximeter 1 in the embodiment of the present invention. This operation program is stored in the ROM 12 and is executed by the CPU 11.

  The CPU 11 first confirms that the memory card 31 has been inserted into the insertion port 14a of the taximeter 1 at the time of delivery (step S1). When the insertion of the memory card 31 is confirmed, the CPU 11 determines the presence or absence of a failure diagnosis code from the in-vehicle computer diagnosis device 32 before leaving (step S2).

  When the failure diagnosis code is found before leaving, the CPU 11 refers to the table 12a and displays the failure content corresponding to the failure diagnosis code on the meter screen 15a of the display 15 (step S3). Further, in step 3, the CPU 11 records the failure diagnosis code and the time counted by the RTC 19 in the memory card 31 and the RAM 13. At this time, the registration number (for example, vehicle body number) of the vehicle is also recorded at the same time.

  5A and 5B are diagrams showing a meter screen 15a for notifying that a failure has occurred. If a failure is found before leaving, for example, as shown in Fig. 5 (A), the meter screen 15a displays messages such as "There is a failure", "Ignition system or misfire", and "Cannot leave". The

  Then, the CPU 11 stops the taxi vehicle exit process (step S4) and ends this operation. Thus, when a failure is found before leaving, the CPU 11 determines that the leaving has failed.

  On the other hand, when a failure diagnosis code is not found before leaving in step S2, the CPU 11 normally performs the leaving process (step S5). In the delivery process, the recording of taxi vehicle travel data (business data) is started.

  CPU11 discriminate | determines the presence or absence of the failure diagnostic code from the vehicle-mounted computer diagnostic apparatus 32 after leaving (step S6). If there is no failure diagnosis code, the CPU 11 repeats the process of step S6.

  On the other hand, if there is a failure diagnosis code in step S6, the CPU 11 determines whether or not the taximeter 1 is in an actual vehicle state (step S7). When the vehicle is not in an actual vehicle state, that is, in an empty vehicle state, the CPU 11 displays the failure content corresponding to the failure diagnosis code on the meter screen 15a of the display unit 15 as in step S3. The time measured is recorded in the memory card 31 and the RAM 13 (step S11). Thereafter, the CPU 11 ends this operation.

  On the other hand, if the vehicle is in an actual state in step S7, the CPU 11 records the failure diagnosis code and the time counted by the RTC 19 in the memory card 31 and the RAM 13 (step S8). In the processes in steps S8 and S11, the vehicle registration number may be recorded at the same time. The CPU 11 waits until the empty button 21a is pressed (step S9).

  When the empty button 21a is pressed, the CPU 11 displays the failure content on the meter screen 15a of the display 15 (step S10). Thereafter, the CPU 11 ends this operation.

  In the display processing in steps S10 and S11, as shown in FIG. 5B, the meter screen 15a includes “no car”, “failure”, “adjustment of fuel and air”, “please enter”. Message is displayed.

  According to the taximeter 1 of the present embodiment, since the presence / absence of a failure is displayed on the meter screen 15a, the driver can be quickly notified of the presence / absence of a vehicle failure. Thereby, when a failure is found before leaving, it is possible to prevent the vehicle from traveling in a state where the vehicle has failed. Further, since the details of the failure are specifically displayed, the driver can roughly grasp the state of the failure.

  In addition, even when a failure is found after delivery, the driver can be notified of the failure as quickly as possible. If a failure is found in an empty state, the driver can be notified immediately of the failure, and even if a failure is found in the actual vehicle state, the passenger gets off and the empty button is pressed. Since the contents of the failure are displayed, it is possible to avoid the possibility of giving passengers more uneasiness than necessary.

  In particular, abnormalities in water temperature and oil temperature, fuel system, engine system, and speed pulse system are not known before leaving the warehouse. Can be prevented in advance.

  Thus, the risk of causing trouble for passengers can be reduced by grasping vehicle troubles in advance. In addition, since the failure diagnosis code for each vehicle is recorded on the memory card before and during delivery, this information can be used for maintenance and repair. Furthermore, since the failure occurrence time is also recorded, more accurate information can be obtained.

  The present invention is not limited to the configuration of the above-described embodiment, and any configuration that can achieve the function of the configuration of the present embodiment is applicable.

  For example, when it is determined that a failure has been found and the delivery has failed, the delivery process has been stopped in the present embodiment, but in addition, the rear processing device on the office side is notified via the communication module. You may do it. In addition, when a failure occurs during delivery, the office-side rear processing apparatus may be similarly notified. As a result, it is possible to give instructions to the driver from the office side, which leads to safety measures.

  Further, in the above embodiment, even if a failure occurs in the actual vehicle, the failure content is not immediately notified to the driver, but when it is determined that the failure content is serious, the failure content is displayed on the meter screen. You may do it. This leads to safety measures in an emergency.
