Description

The present invention relates to an on-board unit that records an operating state of a vehicle.

When managing operation data of a truck vehicle or the like, normally, the on-board unit attached to the vehicle is in the warehousing state, and after loading the vehicle, the driver operates the on-board unit to switch the empty vehicle to the actual vehicle. As a result, the on-board unit records the loading state as the actual vehicle state. Since the actual vehicle state is stored in the internal memory of the on-board unit, the state is maintained. In the case of operation in which the loading state is the actual vehicle state, the crew member performs an operation of switching the empty vehicle to the actual vehicle after loading, so that the empty vehicle state is not erroneously recorded.

On the other hand, there are users (businesses, etc.) who operate the delivery status as the actual vehicle status. In this case, for example, the crew performs an operation to switch to the actual vehicle state at the time of leaving the garage. The fact that the loading state has been switched to the actual vehicle state is stored in the internal memory of the on-board unit. In the case of the operation in which the delivery state is set to the actual vehicle state in this way, the user wants to always keep the on-board unit in the actual vehicle state after the delivery.

As a prior art, there is known an operation recording device that starts a data recording / collecting operation when it detects that a vehicle has traveled a predetermined distance without a driver performing a warehousing operation (see Patent Document 1). Therefore, it is assumed that the on-board unit can be set so as to automatically switch from the empty vehicle state to the actual vehicle state when a predetermined condition is satisfied by using such prior art.

Japanese Unexamined Patent Publication No. 6-331393

However, even if the actual vehicle state is stored in the internal memory of the in-vehicle device, when the in-vehicle device program or the setting file is loaded into the in-vehicle device, the internal memory of the in-vehicle device is initialized and becomes an empty vehicle state. In addition, since the setting to set the warehousing state to the actual vehicle state is also canceled, the on-board unit remains vacant unless the switching operation is performed by the crew at the next warehousing. Therefore, if the crew does not notice that the load has been loaded and forgets to perform the switching operation, the empty vehicle status is recorded as the operation data instead of the actual vehicle status. As a result, there is a problem that the operation data of the actual vehicle state is not correctly reflected in the daily driving report, which may reduce the convenience.

In addition, Patent Document 1 discloses an operation recording device that automatically starts a specific operation without the driver's operation, but regarding the setting of the loading state (actual vehicle state, empty vehicle state) of the vehicle. Is not shown.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an in-vehicle device capable of allowing a user to select an operation related to switching of a set operation state and improving convenience. It is in.

The digital tachograph 10 includes a CPU 11, a volatile memory 26, a non-volatile memory 25, a card I / F18, a voice I / F19, an RTC (clock IC) 17, a SW input unit 22, and a display unit 27.

The CPU 11 comprehensively controls each part of the digital tachograph 10. The non-volatile memory 25 stores an on-board unit program or the like executed by the CPU 11. Further, the non-volatile memory 25 stores the on-board unit program, the setting file 50 (see FIG. 2), and the like after the version upgrade, which are transmitted from the office PC 30. In addition, the non-volatile memory 25 stores an operating state (status) including a loading state of the vehicle. The loaded state represents either a state in which the vehicle is loaded or a state in which the vehicle is not loaded. The status of the vehicle is the actual vehicle state or the empty vehicle state. The vehicle status stored in the non-volatile memory 25 can be switched to an empty vehicle state or an actual vehicle state by the empty vehicle / actual vehicle switching button 22z described later.

Further, the status of the vehicle at the time of warehousing is stored in the memory area 25z of the non-volatile memory 25. This memory area 25z is an area in which data is not erased (initialized) even when the on-board unit program or the setting file 50 is loaded. Further, the non-volatile memory 25 stores the automatic actual vehicle flag f1 at the time of delivery and the initialization flag f2 at the time of delivery. The automatic actual vehicle flag f1 at the time of warehousing is a flag for automatically setting the status of the vehicle to the actual vehicle state when the warehousing operation is performed. When it is 0 (off), the automatic actual vehicle is not set at the time of delivery. The warehousing initialization flag f2 is a flag for setting the vehicle status to initialization (empty vehicle state) when the warehousing automatic actual vehicle setting is not performed, and the value 1 (on) sets the warehousing initialization setting. This is done, and when the value is 0 (off), the initialization setting at the time of delivery is not performed. The non-volatile memory 25 retains data even when the ignition key is turned off and battery power is no longer supplied.

The volatile memory 26 temporarily records operation data and the like. A memory card 65 owned by the crew is freely inserted and removed from the card I / F18. The CPU 11 writes data such as operation data and vehicle status to the memory card 65 connected to the card I / F18. A built-in speaker 20 is connected to the voice I / F19. The built-in speaker 20 emits a sound such as an alarm.

The RTC17 (timekeeping unit) measures the current time. The SW input unit 22 has a switch unit (SWU) arranged in the housing of the digital tachograph 10 and receives a pressing operation by a crew member. The SW input unit 22 includes, for example, a warehousing button 22x, a warehousing button 22y, an empty car / actual car switching button 22z, and the like, and inputs ON / OFF of these buttons. The display unit 27 is composed of an LCD (liquid crystal display) and displays an alarm, a vehicle status (actual vehicle / empty vehicle status), and the like, in addition to a communication and operation status.

A vehicle speed sensor 51 that detects the speed of the vehicle is connected to the speed I / F 12A, and a speed pulse from the vehicle speed sensor 51 is input. The vehicle speed sensor 51 may be provided as an option on the digital tachograph 10, or may be provided as a device separate from the digital tachograph 10. A rotation pulse from an engine rotation speed sensor (not shown) is input to the engine rotation I / F12B. An external device (not shown) is connected to the external input I / F13.

An acceleration sensor (G sensor) 28 that detects acceleration (G value) (sensing an impact) is connected to the sensor input I / F 14, and a signal from the G sensor 28 is input. Signals such as a temperature sensor (not shown) for detecting the engine temperature (cooling water temperature) and a fuel amount sensor (not shown) for detecting the amount of fuel are input to the analog input I / F29. The CPU 11 detects various operating states based on the information input via these I / Fs.

The GPS receiving unit 15 is connected to the GPS antenna 15a, receives a signal transmitted from a GPS satellite, and acquires current position information (GPS information). A handy numeric keypad (H / T) 23 that can be input (pressed) by the crew is connected to the operation input I / F16. Various buttons such as a delivery button are arranged on the handy numeric keypad 23.

When the communication unit 24 performs wide area communication and is connected to the radio base station 8 via the mobile line network (mobile communication network), the communication unit 24 and the office PC 30 are connected to the office PC 30 via a network 70 such as the Internet connected to the radio base station 8. Communicate. The power supply unit 21 supplies electric power to each unit of the digital tachograph 10 by turning on the ignition switch or the like.

On the other hand, the office PC 30 is a PC that operates on a general-purpose operating system. The office PC 30 functions as an operation management device (external device), and has a CPU 31, a communication unit 32, a display unit 33, a storage unit 34, a card I / F35, an operation unit 36, an output unit 37, a voice I / F38, and an external I. Has / F48.

The CPU 31 comprehensively controls each part of the office PC 30. The communication unit 32 can communicate with the digital tachograph 10 via the network 70.

The display unit 33 displays an operation management screen, a daily operation report (see FIG. 7) screen, and the like. The storage unit 34 stores an operation management program or the like that manages the operation status based on the data measured by the digital tachograph 10.

A memory card 65 is freely inserted and removed from the card I / F35. The card I / F35 inputs the operation data measured by the digital tachograph 10 and stored in the memory card 65. The operation unit 36 has a keyboard, a mouse, and the like, and receives an operation of an operation manager (hereinafter referred to as an administrator) of an office PC. The output unit 37 outputs various data. A microphone 41 and a speaker 42 are connected to the voice I / F 38. The administrator can also make a voice call using the microphone 41 and the speaker 42. An external storage device (not shown) or the like can be connected to the external I / F 48.

FIG. 2 is a table showing the registered contents of the setting file 50. The setting file 50 includes various setting items related to the digital tachograph 10. Specifically, in the setting file 50, for example, the vehicle number (No.), the crew identification information (ID), the presence / absence of the automatic actual vehicle setting at the time of delivery (ON / OFF), and the presence / absence of the factory initialization setting (ON / OFF). OFF) and the like are included.

Vehicle No. Is the automobile registration number stipulated by law. In addition, vehicle No. In addition to the automobile registration number, a number assigned by the business establishment for each vehicle may be used. The crew ID is information that identifies the crew. The automatic actual vehicle setting at the time of warehousing is a function that automatically sets the status of the vehicle to the actual vehicle state at the time of warehousing. The warehousing initialization setting is a function of initializing the status of the vehicle stored in the memory area 25z at the time of warehousing and warehousing (here, it is set to the empty vehicle state).

The operation of the operation management system 5 having the above configuration is shown. First, the operation of the digital tachograph 10 will be shown. FIG. 3 is a flowchart showing a status (operating state) management procedure by the digital tachograph 10. First, the CPU 11 of the digital tachograph 10 waits until the warehousing operation is performed (S1).

Here, the warehousing operation is determined by the crew pressing the warehousing button 22x of the SW input unit 22 or the warehousing button of the handy numeric keypad 23. The communication unit 24 of the digital tachograph 10 may determine that the warehousing operation is performed by communicating with a wireless communication device such as an access point installed at a gate that passes at the time of warehousing. In addition, when it is determined that the loading operation is completed on the truck vehicle, for example, the crew member instructs the handy terminal that manages the luggage, which is connected to the digital tachograph so as to be communicable, to complete the loading. Therefore, it may be determined that the digital tachograph is a shipping operation. Further, a sensor for detecting that the luggage door of the truck vehicle is locked is connected to the digital tachograph, and when the digital tachograph detects that the sensor is turned on, it may be determined that the delivery operation is performed.

When the warehousing operation is performed, the CPU 11 determines whether or not the warehousing automatic actual vehicle flag f1 is set to the value 1, that is, whether or not the warehousing automatic actual vehicle setting is ON (ON) (S2). .. When the automatic actual vehicle setting at the time of delivery is on, the CPU 11 sets the vehicle status to the actual vehicle state and stores it in the non-volatile memory 25 (S3). At this time, the CPU 11 holds the status at the time of warehousing, which is stored in the memory area 25z of the non-volatile memory 25, as it is. Here, the status at the time of warehousing is not used and is rewritten when the goods are received again.

The CPU 11 transmits a status command indicating the actual vehicle state to the office PC 30 at the time of leaving the warehouse via the network 70 such as the mobile communication network and the Internet communication network by the communication unit 24 (S4). After this, the CPU 11 ends this operation.

On the other hand, when the automatic actual vehicle setting at the time of delivery is OFF in step S2, the CPU 11 determines whether or not the initialization flag f2 at the time of delivery is set to the value 1, that is, the initialization setting at the time of delivery is ON. Whether or not it is determined (S5). When the delivery time initialization setting is on, the CPU 11 sets the vehicle status to the empty state and stores it in the non-volatile memory 25 (S6). At this time, the CPU 11 erases the status at the time of warehousing stored in the memory area 25z of the non-volatile memory 25.

The CPU 11 transmits a status command indicating an empty vehicle state to the office PC 30 via the network 70 by the communication unit 24 (S7). After this, the CPU 11 ends this operation.

On the other hand, when the warehousing initialization setting is off in step S5, the CPU 11 sets the vehicle status to the status at the time of the previous warehousing and stores it in the non-volatile memory 25 (S8). The status (actual vehicle state or empty vehicle state) at the time of the previous warehousing is stored in the memory area 25z of the non-volatile memory 25. Further, the memory area 25z of the non-volatile memory 25 in which the status at the time of warehousing is stored is an area in which the data is not erased even if the on-board unit program or the setting file is loaded, as described above. Further, the non-volatile memory 25 is a memory that retains data even when the ignition key is turned off and battery power is no longer supplied. Therefore, the status at the time of the previous warehousing is surely held in the memory area 25z of the non-volatile memory 25.

The CPU 11 transmits a status command indicating the operating state (actual vehicle state or empty vehicle state) of the vehicle at the time of the previous warehousing to the office PC 30 via the network 70 by the communication unit 24 (S9). After this, the CPU 11 ends this operation.

Further, in steps S4, S7, and S9, the CPU 11 also records the above status command on the memory card 65 via the card I / F18. As a result, when communication with the office PC is not possible, the office PC 30 can read the status of the vehicle by reading the status command recorded in the memory card 65 into the office PC 30, which will be described later. It can be reflected in the daily driving report 100. Further, in steps S4, S7, and S9, the CPU 11 may display the vehicle status (empty vehicle state or actual vehicle state) on the display unit 27. As a result, the crew member can visually confirm the status of the vehicle stored in the digital tachograph 10.

Here, the digital tachograph sent the vehicle status to the office PC triggered by the warehousing operation, but after warehousing, the crew members used the memory card to warehousing regardless of the communication status. Data including the vehicle status (empty vehicle status or actual vehicle status) may be read into the office PC. This data may include operation data such as vehicle position and vehicle speed, as well as status during delivery. Further, the digital tachograph may transfer the above data to the office PC by wireless LAN communication via an access point installed near the gate at the time of warehousing without using a memory card.

The above processing was the processing at the time of warehousing, but when the vehicle is warehousing, when the crew presses the warehousing button 22y of the digital tachograph 10, the CPU 11 sets the status at the time of warehousing (actual vehicle state or empty vehicle state) to the non-volatile memory 25. It is stored in the memory area 25z of. As a result, the status at the time of the previous warehousing is held in the memory area 25z of the non-volatile memory 25. The warehousing operation is not limited to pressing the warehousing button 22y by the crew member, and the digital tachograph 10 may be performed by receiving a signal from an access point installed near the gate. Further, at this time, the access point may notify the office PC 30 that the vehicle has arrived.

Next, the loading process will be described. Here, the case where the digital tachograph 10 loads the updated setting file 50 is shown, but the present invention is similarly applicable not only to the setting file but also to the case of loading the on-board unit program. In the present embodiment, the loading of the setting file 50 is assumed to be performed during warehousing, but may be performed during warehousing.

FIG. 4 is a flowchart showing a loading process procedure. This process is executed, for example, when the digital tachograph 10 receives data (including a setting file and an in-vehicle device program) related to control of various digital tachographs from the office PC 30.

The CPU 11 of the digital tachograph 10 determines whether or not the setting file 50 is included in the received data, that is, whether or not the setting file 50 is received from the office PC 30 (S21). If the setting file 50 has not been received, the CPU 11 ends this operation.

When the setting file 50 is received, the CPU 11 determines whether or not the setting file 50 is for the own vehicle (own device) (S22). The association between the own vehicle and the setting file 50 is performed depending on whether or not the vehicle number registered in the setting file 50 and the vehicle number of the own vehicle match.

The digital tachograph 10 stores the own device ID, and the own device ID may be associated with the in-vehicle device ID registered in the setting file 50 depending on whether or not they match. Further, when the ON / OFF of the specific vehicle is registered in the setting file 50 and the own vehicle corresponds to the ON of the specific vehicle, the above-mentioned association between the vehicle and the setting file may be confirmed as the next step. .. By enabling ON / OFF of a specific vehicle, for example, it is useful when it is desired to make different settings for each business operator or department of a customer company, or for each vehicle.

If the setting file 50 is for the own vehicle in step S22, the CPU 11 acquires the setting file 50 and performs a status setting change process at the time of delivery (S23). The process of changing the status setting at the time of delivery will be described later. After this, the CPU 11 ends this operation.

On the other hand, if it is not the setting file 50 for the own vehicle in step S22, the CPU 11 discards the received setting file 50 (step S24). After this, the CPU 11 ends this operation.

Here, after receiving the setting file, the digital tachograph determines whether or not the setting file is for the own device, but it may be determined before receiving the setting file. As a result, if it is not intended for the own vehicle (device), unnecessary data communication can be omitted by not loading.

FIG. 5 is a flowchart showing the procedure for changing the status setting at the time of delivery in step S23. The CPU 11 determines whether or not the automatic actual vehicle setting at the time of delivery, which is included in the setting file 50, is ON (ON) (S31). When the warehousing automatic actual vehicle setting is on, the CPU 11 sets the warehousing automatic actual vehicle flag f1 stored in the non-volatile memory 25 to a value 1 (S32). When the warehousing automatic actual vehicle flag f1 is a value 1, that is, when the warehousing automatic actual vehicle setting is on, the CPU 11 switches the status to the actual vehicle state when the warehousing operation is performed. Since the automatic actual vehicle flag f1 at the time of delivery is stored in the non-volatile memory 25, it is retained even when the battery power of the vehicle is turned off. After this, the CPU 11 ends this operation.

On the other hand, when the automatic actual vehicle setting at the time of delivery is OFF in step S31, the CPU 11 determines whether or not the initialization setting at the time of delivery included in the setting file 50 is ON (ON) (S33). .. When the delivery time initialization setting is on, the CPU 11 sets the delivery time initialization flag f2 stored in the non-volatile memory 25 to a value 1 (S34). When the warehousing initialization flag f2 has a value of 1, that is, when the warehousing initialization setting is on, the CPU 11 switches the status to the empty vehicle state when the warehousing operation is performed. Since the initialization flag f2 at the time of delivery is stored in the non-volatile memory 25, it is retained even when the battery power of the vehicle is turned off. After this, the CPU 11 ends this operation.

Next, the operation of the office PC 30 will be shown. FIG. 6 is a flowchart showing an operation management procedure by the office PC 30. This process is executed by the CPU 31 in the office PC 30. The CPU 31 determines whether or not data has been received from the digital tachograph 10 (S51). Here, the case where data is transmitted from the digital tachograph by wireless communication is shown, but as described above, the data recorded on the memory card may be read. Further, when the vehicle is warehousing, the access point installed near the gate may transfer the data to the office PC by wireless LAN communication, so that the CPU 31 may receive the data.

When the data received from the digital tachograph 10 includes the status command at the time of delivery, the CPU 31 acquires the status command at the time of delivery (S52). The CPU 31 stores the status command at the time of delivery in the storage unit 34 together with other operation data acquired from the digital tachograph 10 (S53). Further, in step S53, the CPU 31 displays the operation data, the warehousing / warehousing status, and the status at the time of warehousing (actual vehicle state or empty vehicle state) on the display unit 33 in real time. The operation data includes vehicle position information, mileage, mileage, vehicle speed, time information, and the like.

Then, the CPU 31 creates a daily operation report 100 based on the data stored in the storage unit 34 according to the operation by the administrator of the office PC 30 (S54). After this, the CPU 31 ends this operation. The process of step S54 is executed as a separate routine and may be omitted here.

FIG. 7 is a diagram showing a daily operation report 100. In the daily driving report 100, in addition to the operation data such as the operation date, the mileage, and the travel time, the vehicle No. , Crew ID, actual vehicle distance, actual vehicle rate, status from delivery to warehousing, etc. are recorded. Further, the daily driving report 100 describes ON / OFF of the automatic actual vehicle setting at the time of delivery, ON / OFF of the initialization setting at the time of delivery, and ON / OFF of the specific vehicle setting.

In the daily driving report 100, since the setting of the specific vehicle is ON, the digital tachograph 10 records the operation data. For example, when the crew notifies the digital tachograph 10 of the completion of loading at the handy terminal, this warehousing operation is performed by the operation No. 100 of the daily operation report 100. Recorded as shown in 1. The crew departs the truck, exits the gate of the distribution center, and starts the collection and delivery work. After that, when the truck vehicle returns to the distribution center, the truck vehicle is stopped, and the crew presses the warehousing button 22y of the digital tachograph 10, this warehousing work is performed by the operation No. 100 of the daily driving report 100. Recorded as shown in 2. In this case, the working time is recorded as 3 hours and 33 minutes, and the mileage is 30 km. The status during delivery is recorded as the actual vehicle. Here, since the automatic actual vehicle setting is ON at the time of delivery, the status is switched to the actual vehicle at the same time as the delivery. Further, by pressing the warehousing button 22y, the status is stored in the memory area 25z of the non-volatile memory 25.

Similarly, when the delivery work is started again, when the crew member notifies the digital tachograph 10 of the completion of loading at the handy terminal, this delivery work is performed by the work No. 100 of the daily operation report 100. Recorded as shown in 3. The crew departs the truck, exits the gate of the distribution center, and starts the collection and delivery work. After that, when the truck vehicle returns to the distribution center, the truck vehicle is stopped, and the crew presses the warehousing button 22y of the digital tachograph 10, this warehousing work is performed by the operation No. 100 of the daily driving report 100. Recorded as shown in 4. This working time is recorded as 1 hour and 5 minutes, and the mileage is 10 km. The status during delivery is recorded as the actual vehicle. Further, the daily driving report 100 states that the actual vehicle rate is 80%, which represents the ratio of the actual vehicle distance (40 km) that has been loaded with a load that leads to income to the total mileage (50 km).

In this way, since it is stated in the daily driving report 100 that the status is automatically switched to the actual vehicle when the vehicle is released, it is recorded in the daily driving report while the vehicle is empty due to an operation error by the crew (forgetting to press the exit button, etc.). (Recording error) can be prevented. Therefore, the manager does not need to correct the daily driving report due to the input error of the crew. Conventionally, when there is an input error, it may take time for the operation manager to find the error or it may take time to correct it depending on the location, but such labor is eliminated. As a result, there is no need to create an erroneous daily report due to omission of correction of input errors and to total the actual vehicle rate. In addition, the daily driving report will make the employment status of the crew accurate, and the crew will be able to receive a proper evaluation.

<Advantages of Digital Tachograph 10>
As shown above, the digital tachograph 10 of the present embodiment is mounted on the vehicle and records the operating state including the loading state of the vehicle. The loading state is a state in which luggage is loaded on the vehicle. The CPU 11 of the digital tachograph 10 detects the warehousing and warehousing of the vehicle by pressing the warehousing button 22x, pressing the warehousing button 22y, completing the loading by the handy terminal, and the like (delivery / warehousing detecting means). The CPU 11 performs the processes of steps S3, S6, and S8 to switch the loading state between the actual vehicle state and the empty vehicle state (switching means). The CPU 11 sets whether or not to switch the loading state to the actual vehicle state when the warehousing is detected by setting the automatic actual vehicle flag f1 at the time of warehousing to the value 1 or resetting the value to 0 (first setting means). To do.

In this way, if it is set to switch to the actual vehicle state at the time of warehousing, it will automatically be in the actual vehicle state at the time of warehousing. The operating status can be switched to the actual vehicle status without manual operation. That is, in the case of the operation in which the warehousing state is the actual vehicle state, the operation state can be switched to the actual vehicle state without manually operating the warehousing state. Therefore, it is possible to prevent the vehicle from being recorded in an empty state due to an operation error by the crew.

Further, the CPU 11 of the digital tachograph 10 stores the setting of the loading state in the memory area 25z (storage means) of the non-volatile memory 25 when the warehousing is detected. The data stored in the memory area 25z is not erased even when the on-board unit program or the setting file 50 is loaded (data related to the control of the on-board unit is input). Whether or not the CPU 11 initializes the loading state stored in the memory area 25z to the empty vehicle state by setting the initialization flag f2 at the time of delivery to the value 1 or resetting the value to 0 (second setting means). To set. If the CPU 11 is not set to switch the loading state to the actual vehicle state when the delivery is detected, and is set not to initialize the loading state, the CPU 11 sets the loading state. The loading state stored in the memory area 25z is set.

As a result, it is possible to always set the empty vehicle state at the time of leaving the garage, and it is also possible to set the operating state (actual vehicle state or empty vehicle state) at the time of the previous warehousing stored in the memory area 25z. The same operation as before can be secured.

Further, the digital tachograph 10 includes a communication unit 24 (communication device) that wirelessly transmits the operation status to the office PC 30 (external device) installed outside the vehicle. At least when the loading state is switched, the communication unit 24 performs the processes of steps S4, S7, and S9, and transmits the loading state to the office PC 30.

As a result, the office PC can acquire the operating state (actual vehicle state or empty vehicle state) from the digital tachograph, and the operating state of the vehicle equipped with the digital tachograph 10 has been switched in the office PC 30. It is possible to grasp immediately and correctly create a daily driving report that reflects the actual vehicle condition and the empty vehicle condition.
