Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle operation information collecting apparatus for collecting vehicle operation information including information indicating a speed of a vehicle that changes every moment in the form of digital data, and storing the collected information in a storage medium.

[0002]

2. Description of the Related Art For example, in a business vehicle such as a truck, a taxi, a delivery vehicle, etc., operation information such as a running speed and a running distance of a vehicle that changes every moment, and in a case of a frozen vehicle, operating information such as a temperature in a refrigerator is collected. It is equipped with a vehicle operation information collection device that records, especially in recent years, instead of the analog tachograph that records on the chart paper printed with the old special scale, the collected data is converted into digital data, A vehicle operation information collection device generally called a digital tachograph, which stores this in a storage medium such as an IC memory card, has been widely used.

In this digital type vehicle operation information collecting device, unlike the analog type, the contents of the operation information to be recorded are not determined by the scale printed on the chart paper, and the amount of recordable information is overwhelming. Taking advantage of the fact that there are many vehicles, for example, in the vehicle operation information collection device mounted on the taxi, passengers getting on and off, in the vehicle operation information collection device mounted on trucks and delivery vehicles, such as loading and unloading vehicles An event that occurred during the operation and the time of occurrence are collected instead of or in addition to the current operation information, and stored in a storage medium.

[0004] The operation information and the information on the event during the operation stored in the storage medium during the operation of the vehicle are read out from the storage medium by the analysis device of the management center after the vehicle returns to the management center. It is analyzed and used for creating operation management data.

[0005] By the way, especially in the case of delivery vehicles, there are situations in which delivery cannot be carried out as planned in advance due to road closures and traffic congestion due to accidents and snowfall, or vehicle breakdowns. May occur unexpectedly in the middle of such a case, and in such a case, in some cases, a situation may arise in which another vehicle must be arranged and delivery is taken over.

Conventionally, in such a case, a crew of a vehicle in which an unexpected situation has suddenly occurred reports a report to the management center by telephone and asks for an instruction.

[0007]

However, according to the above-described conventional method, there is no problem if a telephone is nearby, but if not, an unexpected situation suddenly occurs in the vehicle. There is a possibility that time may elapse before the management center grasps the unscheduled situation that has occurred, so that it may be inconvenient to take a post-good measure such as dispatching a substitute vehicle.

That is, for example, when a refrigerated car or a refrigerated car gets stuck due to a breakdown, if there is no telephone nearby and the notification is delayed, and as a result, it is delayed for the management center to grasp this, the replacement of the vehicle will be performed. There is a possibility that inconvenience may occur such that the dispatch is delayed and the value of the cargo is impaired.

[0009] Incidentally, as a device for promptly reporting an unexpected situation that has occurred in a vehicle to another place, for example, a current position emergency notification device disclosed in Japanese Patent Application Laid-Open No. Hei 5-20578 and a device disclosed in Japanese Patent Application Laid-Open No. Hei 9-163028 have been known. There is known an emergency automatic notification device and the like in the publication.

[0010] However, all of these methods automatically transmit predetermined data to a police or other party over a radio telephone line or the like when the occurrence of an accidental impact is detected by a sensor. If the management center is notified of an event that cannot be automatically detected by a sensor or the like based on a predetermined detection criterion, such as traffic stoppage, traffic congestion, or vehicle failure, the application is applied as it is. It is impossible.

In addition, in the case where unexpected situations as described above suddenly occur, the fact that the situation on the vehicle side at that time cannot be grasped to some extent means that necessary measures cannot be taken appropriately. However, by simply applying the conventional technology of automatically reporting the current position of the vehicle at the time of the accident described above, what kind of circumstances have occurred, and what kind of situation the vehicle or cargo is currently in,
In taking measures, it is not possible to notify the management center of information necessary to determine the contents.

The present invention has been made in view of the above circumstances,
It is an object of the present invention to provide a method for automatically detecting a vehicle based on a predetermined detection criterion, such as when a road is closed or congested, or when a vehicle breaks down. The present invention is to provide a vehicle operation information collection device that can promptly notify the management center.

Type designation means C for designating
And the type of road designated by the road type designation unit C is included in the emergency notification vehicle operation information generated by the emergency information generation unit 51B.

According to the vehicle operation information collecting apparatus of the present invention, when the emergency notification operating means 19 is operated, the position information collecting means 51A generated by the emergency information generating means 51B receives the GPS signal. Emergency notification vehicle operation information including the information on the current position of the vehicle collected from the device 15 and at least a part of the vehicle operation information is wirelessly transmitted to the management center 7 by the emergency information communication means A.

Therefore, even when a situation such as a road closure, a traffic jam, a vehicle failure, or the like that cannot be automatically detected by a sensor or the like based on a predetermined detection criterion occurs, The occurrence of the situation is promptly notified to the management center 7 by transmitting the emergency notification vehicle operation information,
In addition, the management center 7 determines the necessary countermeasures based on at least a part of the vehicle operation information included in the emergency notification vehicle operation information. Based on the information on the current position of the vehicle collected from the aircraft 15, the management center 7 can identify a place where the determined measure is to be executed, and can quickly execute the necessary measure corresponding to the situation that has occurred. Becomes

Further, according to the vehicle operation information collecting apparatus of the present invention, the information of the item designated by the emergency notification information item designation means B in the vehicle operation information is transmitted by the emergency information generation means 51B. Since it is included in the generated emergency operation vehicle operation information, the emergency operation is performed according to the operation mode of the vehicle, such as whether the vehicle equipped with the operation information collection device is a taxi or a vehicle for home delivery. The information to be included in the notification vehicle operation information is set from the vehicle operation information, and the versatility can be improved.

Further, according to the vehicle operation information collecting apparatus of the present invention, for example, a general road is extended beside a motorway, and the vehicle runs on one of the roads. In the event that a notification needs to be sent to the management center 7 during the operation, the emergency notification vehicle operation information including the type of road designated by the road type designation means C is transmitted to obtain the position information. The road on which the vehicle is currently located can be specified in combination with the information on the current position of the vehicle collected by the collection means 51A from the GPS receiver 15.

Therefore, if the specified road is a motorway, the management center 7 will determine the nearest interchange from the nearest interchange to the current position. It can be executed efficiently.

If the detected value does not exceed the abnormality detection threshold value (N in step S15c), the external input data collection process is terminated, and the process returns to the main routine of FIG. 10, and if the detected value exceeds the threshold value (step S15c). Y), external input abnormality notification data is generated based on the detection values collected in step S15a, the current position of the vehicle 3 captured in step S11, and the state of the flag F1 in the high-speed flag area of the RAM 51b (step S15). S15d) After notifying the external input abnormality notification data to the management center 7 (step S15e), the external input data collection processing is terminated, and the process returns to the main routine of FIG.

The notification of the external input abnormality notification data to the management center 7 in step S15e is transmitted to the mobile phone 21 via a modem (not shown) and to the telephone 25 of the management center 7 stored in the system data area of the RAM 51b. The telephone number of the management center 7 is automatically transmitted to the telephone number of the management center 7 by automatically calling the external input abnormality notification data generated in step S15d and the current position of the vehicle 3 captured in step S11. This is performed by sending the call to a telephone line formed between them.

When the flag F1 in the high-speed flag area is “0” when the external input abnormality notification data is notified to the management center 7 in step S15e, the current position of the vehicle 3 in the external input abnormality notification data is set to the current position. Data indicating that the vehicle 3 is on a general road is added. If the flag F1 is “1”, data indicating that the vehicle 3 is on an expressway is added to the current position of the vehicle 3 in the external input abnormality notification data.

In step S17, which proceeds after the end of the external input data collection processing, as shown in FIG.
1b, depending on the state of the flag F3 in the actual vehicle flag area,
Based on the traveling pulse input from the traveling sensor 13, a traveling data collection process for calculating the actual vehicle and empty vehicle traveling distance (in km) and the actual vehicle and empty vehicle traveling time (in minutes) in the calculation area is executed.

The travel distance is calculated, for example, by integrating the distance calculated every second based on the travel pulse from the travel sensor 13 and rounding off less than 100 m. Is calculated on the basis of the traveling pulse from the traveling sensor 13 to determine whether the vehicle is running or stopped every second, accumulate in units of seconds, and round off 29 seconds.

The travel distance and travel time calculated while the flag F3 in the actual vehicle flag area is "0" are as follows.
The traveling distance and the traveling time calculated while the flag F3 in the actual vehicle flag area is “1” are accumulated as the empty vehicle traveling distance and the empty vehicle traveling time, and are accumulated as the actual vehicle traveling distance and the actual vehicle traveling time.
