  The present invention relates to an in-vehicle operation management device, an operation management system, and a road segment map data providing method for managing the operation of a vehicle.

  In recent years, an operation management vehicle-mounted device (for example, a drive recorder) that is mounted on a vehicle and records an operation history of the vehicle is often used. By using such an operation management vehicle-mounted device, data such as whether the driver of the vehicle is driving safely or violating the speed is recorded. By analyzing the travel history data, it is possible to evaluate the safe driving for each driver.

  In such an operation management vehicle-mounted device, evaluation may differ between when traveling on a general road and when traveling on a highway. For example, when the vehicle travels at a speed of 80 km / h, it is a speed violation on a general road, but not a speed violation on a highway. Therefore, it is necessary to add to the evaluation information whether the road of the vehicle is a general road or a highway. Conventionally, for example, as described in Japanese Patent Application Laid-Open No. 2008-90348 (Patent Document 1), There has been proposed a method for automatically distinguishing a general road from a highway using data of an ETC in-vehicle device. In other words, if it is detected that the ETC vehicle has entered the highway, it is determined that the subsequent road is a highway, and if it is detected that the ETC vehicle has got off the highway, In addition, it is disclosed that the subsequent road is determined to be a general road.

FIG.

  As shown in FIG. 1, this operation management system includes an in-vehicle operation management device 31 mounted on a vehicle and a server 42 installed in a base station or the like, which are connected via a network 41. Yes. The server 42 includes a control unit 51 that performs overall control, a communication unit 52 that transmits and receives data to and from the in-vehicle operation management device 31 via the network 41, and a road that is provided to the in-vehicle operation management device 31. And a storage unit 53 for storing the section map data. Although FIG. 1 shows an example in which one in-vehicle operation management device 31 is connected to the network 41, a large number of in-vehicle operation management devices 31 are actually connected.

  On the other hand, as shown in FIG. 2, the in-vehicle operation management device 31 includes a control unit 11, a communication unit 17, a GPS module 18, a speaker 19, a display 20, and a nonvolatile memory 16. Further, the in-vehicle operation management device 31 is supplied with electric power from a power source 21 mounted on the vehicle, and also includes vehicle speed data output from the speed sensor 22, rotational speed data output from the engine rotation sensor 23, and various types. Detection data output from the sensor is supplied.

  The communication unit 17 transmits and receives data to and from the server 42 via the network 41 illustrated in FIG. In addition, communication with other communication devices is performed. The GPS module 18 acquires vehicle position information. The nonvolatile memory 16 stores road segment map data in which ordinary roads and expressways are segmented, and records vehicle travel history data.

  The control unit 11 includes a travel path determination unit 12, a mode switching unit 13, an audio output unit 14, and a storage control unit 15. An operation switch 24 is connected to the control unit 11.

  The travel path determination unit 12 determines the travel path of the vehicle based on the road segment map data and the vehicle position information acquired from the GPS module 18. That is, it is determined whether the vehicle is traveling on a general road or a highway.

  When the mode switching unit 13 determines that the vehicle has passed a switching point (a point where the general road and the highway are switched) registered on the road classification map data, the mode switching unit 13 selects the general road driving mode and the highway driving mode. Execute the switching process.

  The storage control unit 15 executes a process of updating the road segment map data stored in the nonvolatile memory 16 as necessary. Further, based on the vehicle travel mode, the vehicle speed, and the engine speed, the vehicle travel history is created, and the created travel history is recorded in the nonvolatile memory 16.

  The voice output unit 14 generates voice data that prompts the user to perform a switching operation when driving a point where it is ambiguous whether or not the vehicle is a switching point, and outputs the voice data to the speaker 19. That is, the audio output unit 14 has a function as a manual operation presentation unit that presents information that prompts the user to perform a switching operation by a manual operation.

  The operation switch 24 is a switch that accepts an input by a manual operation by a user that a general road has entered an expressway or that the expressway has exited a general road.

  In the operation management system according to the present embodiment, when a vehicle occupant enters the highway from a general road or exits from the highway to a general road, an operation input by the operation switch 24 is received. Then, when the operation switch 24 is operated, the position information is transmitted to the server 42 via the network 41, assuming that the position of the vehicle at this time is a switching point. And the server 42 registers a switching point on the road division map data memorize | stored in the memory | storage part 53 based on this positional information.

  By executing such an operation for a large number of in-vehicle operation management devices 31, a large number of switching points are registered on the road segment map data stored in the storage unit 53. Then, by transmitting this road segment map data to the in-vehicle operation management device 31 via the communication unit 52 and the network 41, a large number of switching points are registered in the nonvolatile memory 16 of the in-vehicle operation management device 31. The road division map data thus recorded is stored.

  In addition, the latest road segment map data is stored in the nonvolatile memory 16 by periodically executing this writing operation. When the vehicle travels, the general road travel mode and the highway travel mode are automatically switched when the vehicle travels the switching point based on the road segment map data and the vehicle position data obtained from the GPS module 18. be able to.

  Therefore, the in-vehicle operation management device 31 can recognize whether the traveling road on which the vehicle is traveling is a general road or an expressway, so this information is referred to and the speed of the vehicle A vehicle operation history can be created based on the data, the engine speed data, and the like.

  In addition, when a highway exists on a general road, it may be impossible to accurately determine whether or not the vehicle passes the switching point. That is, when traveling on the lower side, it is traveling on a general road, and when traveling on the upper side, it is necessary to switch between the general road traveling mode and the highway traveling mode when passing the switching point. is there. In the present embodiment, the switching point under such a situation is set as a manual switching point, and when the vehicle passes through the manual switching point, the vehicle occupant is prompted to perform a manual switching operation.

  That is, a sound for prompting a switching operation is output from the speaker 19 at a point before the vehicle passes the manual switching point. Then, the passenger listens to this voice and operates the operation switch 24 to change the travel path when passing the switching point. Further, when the vehicle is traveling on a general road, the operation switch 24 is not operated. By doing so, even if it is ambiguous whether or not to pass through the switching point, it is possible to accurately switch the general road or the highway.

  Next, the processing procedure of the in-vehicle operation management device 31 according to the present embodiment will be described with reference to the flowchart shown in FIG.

  First, in step S11, the control unit 11 determines whether an automatic switching function between a general road and a highway is operating. If the automatic switching function is not activated (NO in step S11), the automatic switching function does not operate (step S12), and the process ends.

  On the other hand, when the automatic switching function is operating (YES in step S11), in step S13, the control unit 11 acquires vehicle position information from the GPS module 18.

  In step S <b> 14, the control unit 11 determines whether or not the vehicle has approached the manual switching point based on the vehicle position information and the road segment map data stored in the nonvolatile memory 16. When it is determined that the vehicle is approaching the manual switching point, the passenger is notified by voice from the speaker 19 that the vehicle is approaching the manual switching point (step S15).

  If it is not approaching the manual switching point, in step S16, the control unit 11 determines whether or not the vehicle has passed the switching point registered on the road segment map data. If not passed (NO in step S16), the process returns to step S13.

  On the other hand, if the vehicle has passed (YES in step S16), in step S17, the control unit 11 determines whether or not the vehicle travel mode is the general road travel mode. The mode is switched to the highway driving mode (step S18). When the vehicle travel mode is the highway travel mode, the mode is switched to the general road travel mode (step S19). Thereafter, this process is terminated.

  In this way, in the in-vehicle operation management device and the operation management system according to the present embodiment, when the switching point is manually input in the vehicle operation management device, the map data is based on the input operation data. Register the switching point above and create road division map data. And based on this road division map data, when a vehicle passes a switching point, a driving mode is switched. That is, when the current travel mode is the general road travel mode, the mode is switched to the highway travel mode, and when the current travel mode is the highway travel mode, the mode is switched to the general road travel mode. Therefore, it is possible to determine whether the vehicle is traveling on a general road or a highway without using ETC passage information as in the past, and it is possible to determine a highly accurate traveling path. .

  In addition, when it is not possible to determine whether or not to pass the switching point, it is set as a manual switching point, and when approaching this manual switching point, switching by manual operation is urged. Therefore, the vehicle occupant performs an operation according to whether or not it is a switching point. Therefore, it can be distinguished with high accuracy whether the traveling road is a general road or an expressway.

  Therefore, it is possible to create an operation history based on information such as the vehicle speed and the engine speed in consideration of the information on the travel route of the vehicle, and more realistic information according to the travel route on which the vehicle has traveled. Can be obtained.

  As described above, the in-vehicle operation management device, the operation management system, and the road segment map data providing method of the present invention have been described based on the illustrated embodiment, but the present invention is not limited to this, and the configuration of each unit is as follows. It can be replaced with any configuration having a similar function.

  For example, in the above-described embodiment, an example has been described in which when a manual switching point is approached, this is notified by voice. However, the present invention is not limited to this, and an image is displayed on the display 20 for notification. Anyway.

  The present invention can be used to create an operation history corresponding to a travel route of a vehicle.
