[0004]

Therefore, if the driver forgets to perform the leaving operation, the leaving operation is not performed, and although the operation of the vehicle is actually started, the operation of recording the vehicle operation information is not performed. There was a problem that the operation record of the vehicle could not be obtained because it was not performed.

Therefore, in view of the above-mentioned conventional problems, the present invention automatically detects the vehicle traveling for a predetermined distance even if the driver does not perform the leaving operation, even if the driver does not perform the leaving operation. It is an object of the present invention to provide a digital vehicle operation recording device which performs a warehousing process and starts a data recording and collection operation.

[0006]

In order to achieve the above-mentioned object, a digital vehicle operation recording device made according to the present invention comprises:
As shown in the basic configuration diagram of FIG. 1, a warehousing and unloading operation unit 2 for performing manual operations for warehousing and warehousing is provided, and warehousing processing and warehousing processing are performed in accordance with warehousing operation and warehousing operation, respectively. After the processing, the operation data of the vehicle including the traveling speed of the vehicle which changes from moment to moment is started to be written and recorded in the storage means 12b by the writing means 11b together with the occurrence time thereof, and the recording and collecting operation is started after the warehousing processing. In the digital vehicle operation recording device to be ended, the traveling detection means 11c for detecting that the vehicle has traveled a predetermined distance in a state where the leaving operation is not performed, and the warehousing processing is automatically performed according to the detection by the traveling detection means. It is characterized in that it is provided with an automatic unloading means 11d for performing.

Are connected. The CPU 11 has an interface (I / F) 13 and a communication interface (I / F) 1.
4 is connected, and a speed signal from a traveling sensor (not shown) and an ignition (IG) (not shown) are connected via the I / F 13.
N) An IGN signal indicating the state of the switch is input. Further, the CPU 11 is the input / output terminal 1 of the communication I / F 14.
Communication is performed with an operating device (not shown) connected via 4a. Further, the display unit 1a is connected to the CPU 11 via the display driver 15, and the normal clock time is displayed on the display unit 1a, but after leaving the garage, the personal code and the mileage are displayed.

FIG. 4 shows the input / output terminal 14 of the vehicle-mounted device 1 of FIG.
An example of the operating device 2 connected to a is shown, in which the same parts as those of the conventional device described above with reference to FIG. 6 are designated by the same reference numerals. The operating device 2 has a microcomputer (CPU) 21 that operates according to a predetermined control program using a battery (not shown) as a power source. The CPU 21 is a ROM 21 that stores a control program
a is built in.

A RAM 22 is connected to the CPU 21, and the RAM 22 stores a work area for storing various data for signal processing, various data collected by itself, and various data input from the vehicle-mounted apparatus 1. And a data area to be written and recorded. The CPU 21 is also connected to a keyboard 2b having various function keys and ten keys and a communication interface (I / F) 24. The CPU 21 also communicates with an in-vehicle device (not shown) connected via the input / output terminal 24a of the communication I / F 24. Further, the display device 2a is connected to the CPU 21 via the display driver 25, and the display device 2a
Displays the key input 0-9.

In the vehicle-mounted device 1 having the above-described structure, the CPU 11 constituting the vehicle-mounted device 1 is initialized when the power is turned on, and in addition to various setting areas such as a clock area and a vehicle code area formed in the work area 12a in the RAM 12, Various flag areas such as the time setting flag are reset, and a signal from a setting device (not shown) connected instead of the operating device 1 connected to the input / output terminal 14a of the communication I / F 14 is waited for. The clock time and vehicle code set by the setting device connected to the input / output terminal 14a are stored in the corresponding areas. Further, when the operation device 2 is connected, a signal for instructing the leaving and entering the warehouse is transmitted to the vehicle-mounted device 1 by communication according to the leaving operation and the entering operation by the specific key. The in-vehicle device 1 performs a warehousing process and a warehousing process according to the warehousing instruction and the warehousing instruction.

When a leaving operation is performed in the operating device 1, a predetermined data collection is started after the leaving operation is performed, and when a leaving operation is performed, a leaving operation is performed in response to the departure operation. To end the data collection,
During the data collection operation from the start to the end of data collection,
The occurrence time data is also recorded. In the above shipping process,
Other addresses such as time and mileage are recorded,
In the warehousing process, in addition to recording time, mileage, etc., various flags are cleared and collection operation is stopped.

In the data collection operation, the CPU 11 inputs, for example, a speed signal generated according to the traveling of the vehicle, processes the speed signal, measures the vehicle speed at every 0.5 seconds, and obtains the value by this measurement. The speed data is compressed and written in the RAM 12. Further, the maximum and minimum values of the speed, the traveled distance, and the like are measured every one minute, and the one-minute time-series data obtained by these measurements are written in the RAM 12.

When the driver forgets to perform the leaving operation and starts the operation on the day and starts traveling, it is determined whether the vehicle has traveled a predetermined distance based on the speed signal input via the I / F 13. If it is determined that the vehicle has traveled for a predetermined distance, the leaving process is performed and the data collection operation is started even if the leaving operation is not performed. When the leaving operation is performed, the identification number of the driver is displayed on the display device 1a that has been displaying the clock until then. This identification number is assigned from the operating device 2 to the in-vehicle device 1 in accordance with the leaving operation of the operating device 2.
It is transmitted together with a signal for instructing the delivery to the warehouse.
Therefore, the driver's identification number cannot be displayed on the display device 1a when the data is collected and the data collection is started without the leaving operation. In such a case, an identification number that is not actually present is displayed. The data is displayed on the display 1a to indicate that the data collection is automatically started without the leaving operation. Of course, the presence or absence of data collection may be instructed by a separately provided indicator.

In the case where the data collection operation is started by carrying out the warehousing according to the traveling of the vehicle for a predetermined distance without the warehousing operation as described above, it is possible to move the data by moving one of the vehicles a little. May start collecting. The data collected in this way is not necessary for daily operation management, but this data may also be downloaded later and be subject to processing.

Therefore, when the data collection is automatically started by traveling, it is not the start of the normal data collection by the leaving operation by the operating device 2, so when the recorded traveling distance has not reached the predetermined distance. The in-vehicle apparatus 1 does not output this data as useless data even if there is a data request. It should be noted that it is also possible to treat unnecessary data as only simple data that is used daily and output detailed data as a series of data.

The details of the operation of the vehicle-mounted apparatus 1 outlined above will be described with reference to the flowchart of FIG. 5 showing the processing performed by the CPU 11 in accordance with a predetermined control program. The CPU 11 starts its operation when its power is turned on, and performs an initializing process in the first step S1. After that, the process proceeds to step S2, and it is determined whether or not the IGN switch is turned on based on the IGN switch state signal input via the I / F 13. When the determination in step S2 is YES, the process proceeds to step S3, where the work area 12 of the RAM 12 is
Clock processing is performed on a clock that keeps time of year / month / day / hour / minute / second, which is configured in the clock area in a, and cumulative distance processing is performed to accumulate a traveling distance as the vehicle travels.

Then, the process proceeds to step S4, where the RAM is
It is determined whether or not the out-of-delivery flag formed in the flag area in the 12 work areas 12a is set to 1. When the determination in step S4 is NO, the process proceeds to step S5a to determine whether or not there is a leaving request by operating the operating device 2. When the determination in step S5a is NO, the process proceeds to step S5b and the vehicle travels a predetermined distance. If it is also NO, the process proceeds to step S10 described later. Step S5a or step S5
When the determination in b is YES, the process proceeds to step S6, the shipping flag is set to 1 and the shipping process is performed, and then the process proceeds to step S10 described later.

If the determination in step S4 is YES and the shipping flag is set to 1, step S7
Then, the process for collecting and recording data is performed here. In this data collection and recording process, speed compression, distance, histogram, idling, and time series data are recorded in the data area 12b of the RAM 12. After that, the process proceeds to step S8, and it is determined whether there is a warehousing request from the operation device 2. When the determination in step S8 is YES and there is a warehousing request, the process proceeds to step S9 to reset the warehousing flag to 0 and carry out the warehousing process. After that, the process proceeds to step S10 described below. When the determination in step S8 is NO, step S9 is skipped and the process proceeds to step S10.

In step S10, the display 1
Normally, a is displayed with a clock, a personal code is displayed and a distance is displayed after leaving the warehouse, and a display processing is performed to display a personal code that is not actually present when the leaving processing is performed without the leaving operation. After this display processing, the process proceeds to step S11 to perform switch input processing. In this processing, status input processing such as IGN switch and various switches (not shown) is performed. Then, the process proceeds to step S12, where communication processing with the controller device 2 is performed. In this communication process, the delivery request signal, the entry request signal, the data request signal, and the like from the operation device 2 are received, and the data and the like are transmitted to the operation device 2.

If the determination is NO, then the process proceeds to step S14a. It is determined whether there is a request for inputting detailed data from the device 2. Step S
If the determination in 14a is also NO, the process returns to step S2.
On the other hand, when the determination in step S13a is YES, the process proceeds to step S13b, and it is determined whether or not the traveling distance from the delivery is a predetermined value or more. When the determination in step S13b is NO, the process returns to step S2. When the determination in step S14a is YES, the process proceeds to step S14b to determine whether or not the traveling distance from the delivery is equal to or more than a predetermined value, and the determination in step S14b is NO.
If, then the process returns to step S2. Furthermore, step S
If the determination in 13b is YES, RA is for data transmission.
The simple data is set in the communication buffer formed in the work area in M12, and the determination in step S14b is Y.
In the case of ES, detailed data is set in the communication buffer, and the process returns to step S2.

When the determination in step S2 is NO, that is, when the IGN switch is off, step S2
The process proceeds to 0 to form the sleep state, and the subsequent step S21.
The clock processing is performed in. Then, the process proceeds to step S22, where it is determined whether or not the shipping flag formed in the flag area in the work area 12a of the RAM 12 is set to 1. When the determination in step S22 is NO, the process proceeds to step S23, and it is determined whether or not there is a leaving request by operating the operating device 2, and this step S23 is performed.
If the determination is YES and there is a delivery request, step S2
After proceeding to step 4 to set the delivery flag to 1 and performing the delivery processing, the process proceeds to step S28 described later. When the determination in step S23 is NO, step S24 is skipped and the process proceeds to step S28.

If the determination in step S22 is YES and the shipping flag is set to 1, step S22
In step 25, the velocity compression data is recorded in the data area 12b of the RAM 12 here. After that, the process proceeds to step S26, where it is determined whether there is a warehousing request from the warehousing / unloading switch 16. When the determination in step S26 is YES and there is a warehousing request, the process proceeds to step S27 to reset the warehousing flag to 0 and carry out warehousing processing. After that, the process proceeds to step S28 described below. Further, the determination in step S26 is N
If O, skip step S27 and skip step S28.
Proceed to.

In step S28, communication processing with the operating device 2 is performed. In this communication process, the delivery request signal, the entry request signal, the data request signal, and the like from the operation device 2 are received, and the data and the like are transmitted to the operation device 2.

Following the communication process of step S28, the process proceeds to step S29a, where it is determined whether or not there is a simple data input request from the operating device 2. If the determination is NO, then the process proceeds to step S30a. It is determined whether there is a request for inputting detailed data from the device 2. Step S
If the determination in 30a is also NO, the process returns to step S2.
On the other hand, when the determination in step S29a is YES, the process proceeds to step S29b, and it is determined whether or not the traveling distance from the delivery is equal to or more than a predetermined value. When the determination in step S29b is NO, the process returns to step S2. If the determination in step S30a is YES, the process proceeds to step S30b to determine whether or not the traveling distance from the leaving is equal to or more than a predetermined value, and the determination in step S30b is NO.
If, then the process returns to step S2. Furthermore, step S
If the determination in step 29b is YES, the flow advances to step S31 to set simple data in the communication buffer formed in the work area of the RAM 12 for transmission, and then in step S31.
When the determination in 30b is YES, the process proceeds to step S32, the detailed data is set in the communication buffer, and then the process returns to step S2.

As is clear from the explanation of the flow chart of FIG. 5, the CPU 11 of the vehicle-mounted device 1 carries out the warehousing process and the warehousing process in accordance with the warehousing operation and the warehousing operation, respectively, and after the warehousing process, the running of the vehicle changes momentarily. A writing means 11b for writing and recording the operation data of the vehicle including the speed in the data area 12b of the RAM together with the generation time thereof, a travel detecting means 11c for detecting that the vehicle has traveled for a predetermined distance in a state where the leaving operation is not performed, a predetermined distance. It functions as an automatic shipping means 11d for automatically carrying out the shipping processing in response to the detection that the vehicle is not running.

Further, the CPU 11 has a data area 12b.
In accordance with a request signal for requesting operation data collected and recorded in the vehicle, a travel distance detecting means 11e for detecting the travel distance of the vehicle after the warehousing processing by this data, the operation data only when the detected distance is a predetermined value or more. Also functions as an output unit 11f that outputs

As described above, when the vehicle travels for a predetermined distance without the leaving operation being performed, the leaving process is automatically performed. Therefore, even if the driver forgets the leaving operation, the operation record of the vehicle is not lost. It is possible to collect the data necessary for operation management even if you forget to leave the warehouse. In addition, regarding the data collected without the leaving operation, when the mileage from the leaving is less than a predetermined value, it is judged that the data does not depend on the operation of the vehicle and is not output even if a data request is made. It also prevents the data from being analyzed.

In the illustrated embodiment, the operation device 2 connected to the in-vehicle device 1 is applied as the in / out operation device, but in addition to this, the in / out switch provided in the in-vehicle device 1 is also applied. Alternatively, the present invention can also be applied to a device in which a reader / writer for an IC memory card is provided in the vehicle-mounted device 2 and insertion / removal of the IC memory card into / from this reader / writer is used as a warehousing operation and a warehousing operation.

[0033]

As described above, according to the present invention, when it is detected that the vehicle has traveled a predetermined distance in the state where the leaving operation is not performed, the leaving process is automatically performed, so that the driver can perform the leaving operation. It is possible to start the data recording and collection operation without forgetting to do so, and to prevent the operation data from not being collected due to forgetting the leaving operation.

When the operation data is requested, the operation data is output only when the traveling distance of the vehicle after the warehousing process is a predetermined value or more, and is not output at other times. By doing so, data collected other than the actual vehicle operation will not be output as operation data, and useless reading and analysis of operation data can be prevented in advance.
