Description

[Technical Field]

[0001] The present invention relates to an event recording device, an in-vehicle device, a traffic management device, an event recording program, and a traffic management program. [Background technology]

[0002] There is a demand for improvements in working conditions, including working hours, for truck drivers. Truck transport companies manage the labor of their drivers based on work records such as daily reports. This labor management utilizes the operation records stored in on-board devices installed in trucks (see, for example, Patent Document 1).

[0003] In light of the recent social problem of excessive driver workloads, new standards regarding working conditions have been established. For example, the newly applied "Standards for the Improvement of Working Hours, etc. of Automobile Drivers" (Improvement Standards Notification) newly stipulates on-duty time, rest time, continuous driving time, etc. within a specified period. On the other hand, this Improvement Standards Notification also stipulates that, under certain conditions, the time spent responding to unforeseen events can be excluded from the application of the regulations regarding on-duty time, driving time, and continuous driving time. In other words, if a driver encounters an unforeseen event such as an accident, breakdown, or disaster, causing a certain delay, the time spent responding to the event can be excluded from the actual driving time.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0016] 1, a traffic management system 100 according to an embodiment is a system operated by a service provider whose clients are businesses that manage the operation of vehicles 1, such as trucks and taxis. The traffic management system 100 includes an on-board device 10 mounted on the vehicle 1, a server 20 that can communicate with the on-board device 10, and an office PC (personal computer) 40 that is a communication terminal that can communicate with the on-board device 10 and the server 20.

[0017] The vehicle-mounted device 10 is mounted on a vehicle 1, such as a truck, and records operational information such as the vehicle 1's entry and exit times, mileage, driving time, driving speed, speed limit, engine RPM limit, sudden start, sudden acceleration, and sudden deceleration. One day's worth of operational information is used, for example, to create a daily report. The vehicle-mounted device 10 can be wirelessly connected to a network N, such as the Internet, via a base station B, for example, via wireless communication. The vehicle-mounted device 10 can operate not only via a communication system that provides vehicle 1 operational information to an office PC 40 via wireless communication, but also via a card system that provides vehicle 1 operational information to the office PC 40 via a recording medium such as a memory card. The vehicle-mounted device 10 is sometimes referred to as a "digital tachometer" or "digital tachograph." Furthermore, as described below, the vehicle-mounted device 10 functions as an event recording device that records abnormalities (tire abnormality events) that occur in the tires of the vehicle 1 by linking with tire sensors mounted on the vehicle 1.

[0018] The server 20 is a computer device that can communicate with the vehicle-mounted device 10 and the office PC 40 via the network N and exchanges operation information of the vehicle 1 with the vehicle-mounted device 10 and the office PC 40. The server 20 is installed, for example, by a service provider.

[0019] The office PC 40 is a communication terminal used by an administrator of a business operator such as a transportation company that operates the vehicle 1, and is capable of communicating with at least one of the vehicle-mounted device 10 and the server 20, or both in this embodiment, via the network N. The communication terminal is not limited to a fixed type, but may also be a portable device such as a tablet, smartphone, or mobile phone. As will be described later, the office PC 40 functions as a traffic management device that outputs daily reports. The office PC 40 may also function as an event recording device instead of the vehicle-mounted device 10.

[0020] 2 is a block diagram showing an example of the configuration of the vehicle-mounted device 10 according to the embodiment. The vehicle-mounted device 10 includes a control unit 11, a communication unit 12, a determination unit 13, a measurement unit 14, a position acquisition unit 15, and a recording unit 16.

[0021] The control unit 11 is a processing unit (computer) that mainly controls the vehicle-mounted device 10. The control unit 11 reads a program stored in an internal memory (not shown) or a recording medium such as a memory card that can be inserted into or removed from the vehicle-mounted device 10, and causes each unit of the vehicle-mounted device 10 to execute predetermined processing. This program may be an event recording program for executing the procedure for recording tire abnormality events, which will be described with reference to FIGS. 4 and 5.

[0022] The communication unit 12 functions as a transmitting unit that transmits operation information of the vehicle 1 to the server 20, the office PC 40, etc. via the network N, and also functions as a receiving unit that receives information from the server 20, the office PC 40, etc.

[0023] The determination unit 13 determines whether the condition of the tires mounted on the vehicle 1 is normal or abnormal based on the air pressure of the tires. The determination unit 13 receives tire air pressure data from tire sensors mounted on the vehicle 1 periodically, for example, every few seconds to every few tens of seconds, and determines the condition of the tires. The tire sensor is, for example, a tire pressure monitoring system (TPMS), which can monitor the tire temperature in addition to monitoring the tire air pressure. The determination unit 13 can determine the condition of the tires based on the tire air pressure obtained at a predetermined interval.

[0024] Based on the time-series data of tire pressure, the measurement unit 14 measures the response time, which is the time from when the determination unit 13 determines that the tire is abnormal to when it determines that the tire is normal. The response time is the time it takes the driver to respond to a tire abnormality, specifically a puncture. Because a tire puncture is included in the category of unforeseen events in the Improvement Standards Notification, the response time here is a time that can be excluded from the application of regulations such as driving time and continuous driving time. Note that the determination unit 13 and the measurement unit 14 may be software realized by a program stored in an internal memory or recording medium (not shown) of the control unit 11.

[0025] The position acquisition unit 15 acquires position information (including latitude and longitude) of the vehicle 1 from the GPS satellites S. The acquired position information is linked to time information and recorded as part of the operation information.

[0026] The recording unit 16 records the collected operation information in an internal memory or a recording medium. When the determination unit 13 determines that the condition of the tires of the vehicle 1 is abnormal, the recording unit 16 records the operation information including the response time and tire abnormality event measured by the measurement unit 14. The recording unit 16 also records the time-series data of tire pressure received from the tire sensors and the determination results by the determination unit 13.

[0027] 3 is a block diagram showing an example of the configuration of the office PC 40 according to the embodiment. The office PC 40 includes a control unit 41, a communication unit 42, an operation information acquisition unit 43, a calculation unit 44, and a daily report output unit 45.

[0028] The control unit 41 is a processing unit (computer) that mainly controls the office PC 40. The control unit 41 reads a program stored in an internal memory (not shown) and causes each unit of the office PC 40 to execute a predetermined process. This program may be a traffic management program for executing the traffic management procedure described in FIG. 6.

[0029] The communication unit 42 functions as a receiving unit that receives operation information of the vehicle 1 from the in-vehicle device 10 or the server 20 via the network N, and also functions as a transmitting unit that transmits information to the server 20, the office PC 40, etc. The office PC 40 is provided with a card interface (I / F), and the control unit 41 may read data from a recording medium removed from the in-vehicle device 10 via the card I / F, as will be described later.

[0030] The operation information acquisition unit 43 acquires operation information including tire abnormality events from the vehicle-mounted device 10. The operation information acquisition unit 43 may acquire the operation information directly from the vehicle-mounted device 10 or may acquire it via the server 20.

[0031] When the operation information acquisition unit 43 acquires the cumulative operation time of the vehicle 1 as operation information, the calculation unit 44 calculates the time obtained by subtracting the response time from the cumulative operation time as the on-duty time. On-duty time is working time, rest time, and other time that the vehicle is on-duty due to the employer.

[0032] The daily report output unit 45 outputs a daily report including a message indicating that a tire abnormality event has been responded to, the location of the response, and the time of the response, based on the operation information. The daily report may be in the form of digital data or a paper medium. The daily report output unit 45 may include a display device that displays digital data, or may include a printer that can print paper media.

[0033] 4 and 5 are flowcharts showing the procedure for recording a tire abnormality event executed by the vehicle-mounted device 10, which is an example of an event recording device. When the control unit 11 of the vehicle-mounted device 10 detects that the vehicle 1 has left the garage (step S1), the determination unit 13 of the vehicle-mounted device 10 starts receiving data including tire pressure output from the tire sensor (step S2). The determination unit 13 periodically receives data including tire pressure from the tire sensor. The received time-series data of tire pressure is stored by the recording unit 16. Next, the determination unit 13 determines whether or not an air pressure equal to or lower than a specified value has been detected from the received data (step S3). The specified value is, for example, the air pressure that the tire must meet in order for the vehicle 1 to run normally, and is a value for determining the state of the tire. The specified value is stored, for example, in an internal memory or a recording medium, and can be set or changed according to the normal air pressure for each tire or vehicle model.

[0034] If the tire pressure is not detected to be equal to or lower than the specified value (No in step S3), the determination unit 13 continues to receive data from the tire sensor. If the tire pressure is detected to be equal to or lower than the specified value (Yes in step S3), the determination unit 13 determines whether the vehicle 1 has stopped (step S4). The determination unit 13 can determine whether the vehicle 1 has stopped based on information about the speed of the vehicle 1 obtained from, for example, a speedometer of the vehicle 1. The time-series data may include information about the speed of the vehicle 1. The criterion for determining whether the vehicle has stopped is, for example, whether the speed is 0 km / h.

[0035] If it is determined that the vehicle 1 is not stopped (No in step S4), the determination unit 13 continues to receive data from the tire sensors. If the determination unit 13 determines that the vehicle 1 has stopped (Yes in step S4), the measurement unit 14 starts measuring time to measure the driver's response time (step S5).

[0036] The determination unit 13 determines whether the vehicle 1 continues to be stopped (step S6). If it is determined that the vehicle 1 is not stopped (No in step S6), the determination unit 13 continues to receive data from the tire sensors. If it is determined that the vehicle 1 is stopped (Yes in step S6), the determination unit 13 determines whether the measurement time started by the measurement unit 14 in step S5 has exceeded a predetermined time (step S7). The predetermined time is, for example, 10 minutes, which is a time estimated to be required for the driver to respond to a tire abnormality event, and the setting can be changed by the user.

[0037] If it is determined that the measured time has not passed the predetermined time (No in step S7), the determination unit 13 determines whether the vehicle 1 is still stopped (step S6). If the determination unit 13 determines that the measured time has passed the predetermined time (Yes in step S7), the recording unit 16 temporarily records the tire abnormality event and the position information of the vehicle 1 acquired by the position acquisition unit 15 in the internal memory (step S8). Steps S3 to S8 are a tire puncture (tire abnormality) determination process.

[0038] Furthermore, the determination unit 13 determines whether or not an air pressure equal to or greater than the above-mentioned specified value has been detected from the data received from the tire sensors (step S9). If it is determined that an air pressure equal to or greater than the specified value has been detected (Yes in step S9), the determination unit 13 determines whether or not the vehicle 1 has started to travel (step S10). The criterion for whether or not the vehicle 1 has started to travel is, for example, whether or not the speed is equal to or greater than 2 km / h.

[0039] When the determination unit 13 determines that the vehicle 1 has started traveling (Yes in step S10), the measurement unit 14 ends the time measurement that started in step S5, and the recording unit 16 temporarily records the operation information including the corresponding time in the internal memory (step S11). Steps S9 to S11 are processing for determining whether the tire change is complete.

[0040] If the vehicle-mounted device 10 is operated in a manner of communicating with an external device such as the office PC 40 via the network N (step S12), the communication unit 12 transmits data including the recorded operation information to the office PC 40 (step S13). The communication unit 12 may transmit the data to the server 20, and the server 20 may transmit the data to the office PC 40.

[0041] On the other hand, if the operation mode of the vehicle-mounted device 10 is not the communication mode but the card mode, the recording unit 16 records data including the operation information on a recording medium such as a memory card (step S15).

[0042] When the data transmission is completed (Yes in step S14) or when the recording to the memory card is completed (Yes in step S16), the control unit 11 discards the data temporarily recorded in the internal memory (step S17).

[0043] 6 is a flowchart showing the procedure of operation management executed by the office PC 40, which is an example of an operation management device. When the entry of the vehicle 1 is detected (step S21), if the operation mode of the in-vehicle device 10 employs a communication method (Yes in step S22), the communication unit 42 of the office PC 40 receives data including operation information from the in-vehicle device 10, and the control unit 41 starts the daily report recording process (step S24). If the operation mode of the in-vehicle device 10 does not employ a communication method (No in step S22), the control unit 41 reads the data including operation information from the recording medium removed from the in-vehicle device 10 by the driver (step S23), and starts the daily report recording process (step S24).

[0044] When the operation information acquisition unit 43 acquires operation information from the communication unit 42 and the acquired operation information does not include a tire abnormality event (No in step S25), the daily report output unit 45 outputs a normal daily report that does not include information related to the tire abnormality event (step S28). On the other hand, when the operation information includes a tire abnormality event (Yes in step S25), the control unit 41 searches for the corresponding location where the puncture was repaired from the location information included in the operation information (step S26).

[0045] The calculation unit 44 refers to the driver's response time and the cumulative driving time of the vehicle 1 included in the driving information and calculates the daily on-duty time (step S27). The calculation unit 44 calculates the on-duty time as the time obtained by subtracting the driver's response time from the cumulative driving time for a predetermined period (one day). The daily report output unit 45 outputs a daily report including information that a tire abnormality event was responded to, the response location, and the response time (step S28).

[0046] As described above, the vehicle-mounted device 10 of this embodiment can record, as a tire abnormality event, the response time, which is the time from the occurrence of the abnormality until the vehicle 1 is restored to normal when a tire abnormality such as a tire puncture occurs, as a tire abnormality event (step S8). For example, the response time, which is the time required from the time a tire puncture occurs until repair is completed, can be automatically recorded. Therefore, the information recorded as a tire abnormality event by the vehicle-mounted device 10 can be output as a daily report by the office PC 40 or the like (step S28). Therefore, a daily report in which the response time to a tire puncture, which is one of the unpredictable events, is excluded from the driver's on-duty time can be output without the administrator having to manually calculate or enter the information. This reduces the administrator's workload and prevents human error due to manual input, making management easier.

[0047] In particular, the determination unit 13 of the vehicle-mounted device 10 can determine that the tire condition is abnormal if the tire pressure is equal to or lower than a specified value and the vehicle 1 is stopped (steps S3 to S6). Therefore, even if the output of the tire sensor contains erroneous data due to noise or the like, the determination will not be made that there is an abnormality unless the vehicle 1 is stopped, so that erroneous detection of tire abnormalities can be prevented and unnecessary event recording can be prevented.

[0048] The determination unit 13 may determine whether the tire condition is normal or abnormal based on the tire temperature in addition to the tire pressure. The tire sensor can sequentially acquire and transmit the tire temperature as well as the tire pressure to the in-vehicle device 10, so the determination unit 13 can use these time-series data transmitted from the tire sensor. The determination unit 13 may predict a tire abnormality based on the correlation between the tire temperature and the tire pressure, taking advantage of the fact that the tire pressure changes depending on the tire temperature. In this way, the determination unit 13 determines the tire condition based on the tire temperature in addition to the tire pressure, and therefore, for example, by determining that a tire temperature that is lower than the atmospheric temperature is abnormal, it can detect an abnormality before a tire puncture occurs.

[0049] The vehicle-mounted device 10 is equipped with a location acquisition unit 15 that acquires location information of the vehicle 1, and the recording unit 16 can also record the location information when a tire condition is determined to be abnormal, along with the driver's response time, as a tire abnormality event. This records location information in addition to the driver's response time, making tire abnormality event information more comprehensive. The vehicle-mounted device 10 is installed in the vehicle 1 and can easily acquire tire abnormality events.

[0050] Furthermore, according to the office PC 40 of this embodiment, the daily report output by the daily report output unit 45 includes tire abnormality events (steps S25 to S28), making it easier to comply with standards excluding response times for unexpected events.

[0051] The office PC 40 includes a calculation unit 44 that calculates the commitment time. When the operation information acquisition unit 43 acquires the cumulative operation time of the vehicle 1 as operation information, the calculation unit 44 can calculate the time obtained by subtracting the response time from the cumulative operation time as the commitment time. The daily report output unit 45 can output a daily report that includes the commitment time. As a result, the daily report includes the commitment time excluding the response time, making it easier to comply with standards that exclude response time for unforeseen events.

[0052] Furthermore, the daily report output unit 45 may output a daily report including a map showing the corresponding location based on the location information. This allows the daily report to include a map showing the corresponding location, thereby making the information in the daily report more comprehensive. FIG. 7 is an example of a map shown in the daily report, and the position P of the vehicle 1 is shown on the map. For example, by displaying the following information in the daily report along with this map, the manager can easily understand the situation. "Response to unexpected events" Yes (1 item) Reason: To repair a flat tire "Response time" 03:59:11.0 "Detention time" 13:48:12.5-03:59:11.0=09:49:01.5 "Location" Address, latitude and longitude information

[0053] In the embodiment, the vehicle-mounted device 10 measures the response time and records the tire abnormality event, but the office PC 40 may function as an event recording device that measures the response time and records the tire abnormality event. In this case, the office PC 40 acquires operation information including time-series data such as tire pressure, speed of the vehicle 1, and location information from the vehicle-mounted device 10 via the network N, and then measures the response time and records the tire abnormality event.

[0054] Here, the features of the embodiments of the event recording device, the operation management device, the in-vehicle device, the event recording program, and the operation management program according to the present invention will be briefly summarized and listed below in [1] to

[0056] According to the event recording device configured as described in [1] above, when a tire abnormality occurs, such as a tire puncture, that renders the vehicle inoperable, the time from the occurrence of the abnormality until the vehicle returns to normal (response time) can be recorded as a tire abnormality event. For example, the response time, which is the time required from the time a tire puncture occurs until repair is completed, can be automatically recorded. Therefore, since the information recorded as a tire abnormality event can be output as a daily report, a daily report in which the response time to a tire puncture, which is one of the unpredictable events, is excluded from the driver's working time can be output without the manager having to manually calculate or enter the information. This reduces the workload of the manager and prevents human error due to manual input, making management easier.

[0058] According to the event recording device having the configuration [2] above, even if the output of the tire sensor contains erroneous data due to noise or the like, it will not be determined to be an abnormality unless the vehicle is stopped, thereby preventing erroneous detection of tire abnormalities and unnecessary event recording.

[0059] [3] The determination unit (13) determines whether the tire is in a normal state or an abnormal state based on the tire temperature in addition to the air pressure. The event recording device according to [1] above.

[0060] According to the event recording device having the configuration [3] above, the tire condition is determined based on the tire temperature as well as the tire pressure. For example, if the tire temperature is lower than the atmospheric temperature, it is determined to be abnormal, thereby making it possible to detect abnormalities before the tire goes punctured.

[0061] [4] A location acquisition unit (15) for acquiring location information of the vehicle is provided. the recording unit records, as the tire abnormality event, the position information at the time when the tire condition is determined to be abnormal, together with the response time. The event recording device according to [1] above.

[0064] According to the on-board device having the configuration [5] above, the on-board device mounted on the vehicle records tire abnormality events, so that tire abnormality events can be easily acquired.

[0065] [6] An operation information acquisition unit (43) that acquires operation information including the tire abnormality event from the on-board device described in [5] above; a daily report output unit (45) that outputs a daily report including at least a response time based on the operation information. Operation control device (office PC40).

[0066] According to the operation management device having the configuration described above in [6], since the daily report includes tire abnormality events, it becomes easy to comply with standards other than the response time for unforeseen events.

[0067] [7] A calculation unit (44) for calculating a restraint time, the operation information acquisition unit acquires, as the operation information, a cumulative operation time of the vehicle; the calculation unit calculates the time obtained by subtracting the response time from the cumulative operation time as the restraint time, the daily report output unit outputs the daily report including the on-duty time. The traffic management device described in [6] above.

[0068] According to the operation management device having the configuration described above in [7], the daily report includes the on-duty time excluding the response time, so that it becomes easy to comply with the standard excluding the response time for unforeseen events.

Operation control device.

[0070] According to the operation management device having the configuration described above in [8], the daily report includes a map showing the corresponding locations, so the information in the daily report becomes more comprehensive.

[0072] According to the event recording program configured as described above in [9], when a tire abnormality such as a flat tire occurs that renders the vehicle inoperable, the time from the occurrence of the abnormality until the vehicle returns to normal (response time) can be recorded as a tire abnormality event. For example, the response time, which is the time required from the time a tire goes flat until repair is completed, can be automatically recorded. Therefore, since the information recorded as a tire abnormality event can be output as a daily report, the administrator can output a daily report excluding the response time to a flat tire, which is one of the unpredictable events, from the driver's working time, without having to manually calculate or enter the information. This reduces the administrator's workload and prevents human error due to manual input, making management easier.
