Description

  The present invention relates to an operation management control device and a control method for operating an alarm system that prevents a vehicle speed violation.

As a warning system for preventing a vehicle speed violation, there is a method for giving a warning to a driver by generating an alarm or changing a display color when an alarm device fixedly attached to the vehicle exceeds, for example, 120 km / h. Are known. Alternatively, the publication (Japanese Patent Laid-Open No. 4-225500) discloses that the navigation device gives a warning to the driver when the speed exceeds the legal speed limit at the travel position and automatically limits the vehicle speed.
In addition, when the operation manager uses a tachometer (or digital tachometer) to instruct the driver to observe the speed on a business vehicle, the business vehicle examines the tachometer records after returning. I am doing so.

  As described above, in the conventional method, a warning is given after a speed violation occurs, or guidance is given as a precaution after the end of work, and the speed violation during driving cannot be prevented in advance.

  In addition, the occurrence of such an overspeed tends to occur in the same place depending on the form of the road, such as a downhill road or a road that has a long straight road, and it tends to occur for each driver. There is a tendency to depend on driving tendency.

Therefore, it is a problem to grasp a road point where a speed excess is likely to occur when the vehicle travels, and to perform a vehicle operation in advance so that the driver does not exceed the speed before passing the point.
In addition, road points where the vehicle should be operated in advance so as not to exceed the speed are determined depending on the driver who operates the vehicle because the road point where the speed is likely to exceed depends on the driving tendency of the driver. It is.

  In order to solve the above-described problems, the present invention is a control device that performs read / write control of information with respect to an external recording medium used for operation management. The driver identification number and the maximum speed to be observed are written, the maximum speed to be observed recorded on the recording medium is compared with the vehicle speed detected from the vehicle speed detection means, and detected by the vehicle speed detection means. When the vehicle speed exceeds the vehicle speed to be observed, the overspeed position detected by the vehicle position detecting means is recorded on the recording medium.

  Further, the invention of claim 2 is a step of reading the maximum speed to be observed from an external recording medium in which the driver identification number and the maximum speed to be observed are written by the operation manager, and reading from the external recording medium Comparing the maximum speed to be observed and the vehicle speed detected by the vehicle detection means, and if the vehicle speed exceeds the maximum speed to be observed, the overspeed position detected by the vehicle position detection means is Recording on a recording medium.

  As described above in detail, according to the vehicle speed warning device according to the present invention, when the traveling vehicle is detected before a position where the speed is likely to be exceeded, the driver is alerted to prevent overspeed. Since the warning warning is output, it is possible to prevent the traveling speed from being exceeded. Further, when it is determined that speed compliance is achieved based on the subsequent speed compliance performance of the driver, the output of the warning warning at the position where the speed is likely to be exceeded is canceled.

  A speed alarm device according to an embodiment of the present invention will be described.

  FIG. 1 is a diagram for explaining the configuration of a speed alarm device A according to an embodiment of the present invention.

  Reference numeral 1 denotes a position detection device that calculates and outputs the latitude and longitude of the current location, receives radio waves from a GPS satellite (not shown), calculates and outputs the latitude and longitude. Reference numeral 2 denotes a vehicle speed sensor that measures the speed of the vehicle, and includes, for example, a wheel rotation speed sensor that outputs a signal synchronized with the rotation of the wheel.

Reference numeral 3 denotes a map database of map information (road data, etc.), which is composed of a CD-ROM (or DVD-ROM) etc. on which map data is recorded and a reader thereof, and is a road necessary for specifying the road at the vehicle position Data of specifications (road type, longitude and latitude coordinates of road link) and the like are stored, and the data is read out as necessary. Reference numeral 4 denotes an operation unit for the user to operate the speed alarm device A, which includes a push button switch, a joystick, and the like.

Outputs guidance information. Reference numeral 6 denotes a display unit for displaying a map and the like, which includes a liquid crystal display panel and the like.

  Reference numeral 7 denotes an acoustic device that generates an alarm sound from the speaker 71 based on a signal from the control unit 10. In this embodiment, an alarm sound signal is applied to an amplifier circuit of an audio device such as a radio or a disk player. ing. Reference numeral 8 denotes an external memory that externally provides data necessary for the processing of the control unit 10 and is composed of an IC card or the like and is detachably attached via an IC card slot or the like. The external memory 8 records in advance destinations necessary for work, travel route guidance data, driver IDs (identification numbers), etc., before operation of the vehicle, and is used by the operation manager after the vehicle has completed the work. Traveling performance data and tachometer data (time, distance, speed) are recorded. Further, the external memory 8 stores the maximum speed to be observed by the vehicle as the speed warning device A (threshold value set for each road type such as a highway and a general road), and the history of the excess position exceeding the maximum speed to be observed. The degree (coordinates), the speed compliance degree at the excess position once exceeded, and the like are stored.

  Reference numeral 9 denotes a rewritable internal memory that is used to store data and retains the stored contents even when the control unit 10 is not in operation. The rewritable internal memory 9 includes a memory such as a RAM to which backup power is supplied. Necessary data is stored, for example, the ID (identification number) of the driver, the excess position exceeding the maximum speed to be observed, the speed compliance degree at the excess position after exceeding, and the like are stored. 10 is a vehicle speed monitor based on signals from the position detection device 1, vehicle speed sensor 2, map database 3, operation unit 6, external memory 8, etc., and map data relating to the vehicle position (current latitude and longitude (coordinate) data). , Over-speed position, position a predetermined distance before the over-speed position), output of warning signal to notify the position where over-speed occurred in the past, registration of over-speed over position, registration deletion processing, etc. The control unit is composed of a microcomputer.

  In the operation management of the business vehicle, the operation manager hands over the external memory 8 storing the relevant data to each driver before departure. The driver attaches the external memory 8 to the vehicle speed alarm device A via an IC card / slot, etc., and the latitude / longitude (coordinates) data of the excess position exceeding the maximum speed to be observed in the past or once exceeded The speed compliance frequency at the later excess position is input to the speed warning device A as data for each driver.

Further, the maximum speed to be observed is set by the operation manager through data stored in the external memory 8, for example, 120 km / h on a highway, 60 km / h on a general road, and the like.
In addition, the above-mentioned data (longitude and latitude (coordinates) data of the excess position that exceeded the maximum speed that should be observed in the past, the speed compliance frequency at the excess position once exceeded, the maximum speed to be observed, and the driver identification) It is also possible to store the number (ID) or the like in the internal memory 9 and operate the speed alarm device A. In this case, the driver identification number (ID) is input to the speed warning device A from the operation unit 4 or at least the external memory 8 in which the driver identification number (ID) is stored, and the driver identification process is performed. A warning for each driver is executed. As described above, the data stored in the external memory 8 (or the internal memory 9) is provided for each driver, and an alarm operation according to the individual driving characteristics is enabled.

Since the speed alarm device A is configured in this way, it becomes possible to store the longitude and latitude (coordinates) data of the excess position exceeding the maximum speed to be observed in the past, and the stored longitude and latitude (coordinates) position can be stored. When passing, it becomes possible to issue an alarm that speed compliance is required in advance from a predetermined distance.
Further, the speed warning device A can be operated based on the past driving history for each driver by processing data based on the driver identification number (ID). Also, instead of registering and warning the excess position for each driver, the data is shared and processed for each vehicle group managed in the operation management business etc., and the speed warning device A is based on the shared past driving history. Can also be operated.

  Next, a process performed by the control unit 10 relating to an alarm output at a place where an excessive speed is likely to occur will be described based on the maximum speed to be observed by the vehicle, with reference to FIG. FIG. 2 is a flowchart of a speed alarm process performed by the control unit 10.

  This process is repeatedly performed while the speed alarm device A is activated and the vehicle is running. In step S1, it is determined whether or not the vehicle is in a traveling state. If the vehicle is traveling, the process proceeds to step S2, and if the vehicle is not traveling, the process is terminated. In step S2, the position (longitudinal latitude / longitude coordinates) of the current location of the vehicle is acquired based on the signal from the position detection device 1, and the process proceeds to step S3. In step S3, the road type (highway or general road) of the current location of the vehicle is acquired based on the road guidance information, and the process proceeds to step S4.

In step S4, the front position (longitude and latitude coordinates) on the travel route at a predetermined distance ahead from the position of the current location of the vehicle (longitude and latitude coordinates) is acquired, and the process proceeds to step S5. The predetermined distance ahead is set to a distance sufficient to adjust the speed while the driver is conscious of preventing excessive speed. The predetermined distance in front is preferably a travel distance of 30 to 60 seconds, for example, and is set to 1 km for a highway and 500 m for a general road, for example. In step S5, it is determined whether or not the current position is an alarm position depending on whether or not the current position is between the forward position (longitude and latitude coordinates) and the excess position (longitude and latitude coordinates) that exceeded the maximum speed that the vehicle should comply with in the past. If the alarm position is determined, the process proceeds to step S6, and if not, the process proceeds to step S7. Note that the registered (stored) data stored in the external memory 8 (or the internal memory 9) is used as the data of the excess position (latitude and longitude coordinates) referred to.
In step S6, since the excess position where the vehicle has exceeded the maximum speed that must be observed in the past is within the predetermined distance, a warning warning is issued that “it is easy to overspeed” and “be careful of overspeed”, Control goes to step S7. The warning warning to the driver is performed using a voice warning output from the sound output circuit 7 (including the speaker 71) or a display on the display unit 6.

In step S7, the maximum speed that the vehicle should comply with is input from the external memory 8 (or internal memory 9) in correspondence with each road type (highway or general road) of the current location, and the process proceeds to step S8. . In step S8, the vehicle speed is input based on the signal from the vehicle speed sensor 2, and the process proceeds to step S9. In step S9, it is determined whether the speed of the vehicle does not exceed the maximum speed to be observed. If it exceeds, the process proceeds to step S10, and if not, the process proceeds to step S13. In step S10, it is determined whether or not an excess position (longitude / latitude coordinate) exceeding the maximum speed to be observed is registered (stored) in the current position (longitude / latitude coordinate). If already registered (stored), step S12 is performed. If not registered (stored), the process proceeds to step S11.
In step S11, the excess position (longitude and latitude coordinates) exceeding the maximum speed that the vehicle should comply with is registered (stored) in the external memory 8 (or internal memory 9), and the process proceeds to step S12. In this way, when the maximum speed that the vehicle should comply with is newly exceeded, a new excess position (latitude and longitude coordinates) is newly registered (stored). In step S12, after the counter (the position of excess speed (latitude and longitude coordinates) stored in association with the data of the excess position (longitude and latitude coordinates) exceeding the maximum speed to be observed is registered, the speed is set to the same point. This counts the number of times the vehicle has traveled in compliance and resets it (returns it to zero).

In step S9, it is determined whether or not the speed of the vehicle exceeds the maximum speed to be observed, and processing in the case where it does not exceed (that is, when the maximum speed is observed) will be described in step S13 and subsequent steps.
In step S13, it is determined whether or not an excess position (longitude and latitude coordinates) exceeding the maximum speed to be observed in the current location has been registered (stored) in the past, and if already registered (stored), the process proceeds to step S14 to register (store) If it is not memorized, the process is terminated.
In step S14, after the counter (the position of excess speed (latitude and longitude coordinates) stored in association with the data of the excess position (longitude and latitude coordinates) exceeding the maximum speed that the vehicle should comply with is registered, Count the number of times the vehicle has traveled in compliance with the speed) (+1), and proceed to step S15. In step S15, it is determined whether the counter (the number of times the vehicle has traveled in accordance with the speed at the same point after the position of overspeed (coordinates) is registered) is greater than a predetermined value α (for example, 3). If YES in step S16, the process ends.
In step S16, the excess position (longitude and latitude coordinates) exceeding the maximum speed that the vehicle should comply with is erased from the external memory 8 (or internal memory 9), registered (stored) and deleted, and this process ends. In this way, although it is a point where overspeed occurred in the past, speed compliance was continuously performed 4 times (α> 3 times) in this pass, and the driver's attention at the same point was recovered, When it is determined that the alarm at the same point is no longer necessary, the registration of excess position (memory) at the same point is deleted from the external memory 9 (or the internal memory 9), and the warning warning at the same point is canceled. Become.

  By the above processing, for each driver, the excess position (latitude and longitude coordinates) is registered (stored) in the external memory 8 (or the internal memory 9) when the maximum speed that the vehicle should comply with is exceeded. The next time you drive on the same road position, the vehicle will comply between the predetermined distance (for example, 1 km for highways and 500 m for ordinary roads) before the point where there was a violation of speed compliance in the past. A warning that a point where the maximum speed to be exceeded is likely to be exceeded is immediately present, that is, a warning warning that the vehicle speed should be maintained within the maximum speed to be observed is output. In addition, the warning warning output at the excess position (latitude and longitude coordinates) indicates that the driver's driving tendency has been improved when the driver repeatedly observes the speed (for example, four times of compliance) during the subsequent driving. Judgment is canceled.

  The above embodiment is applied to a scene of operation management of a business vehicle, and the operation manager gives business instruction information to a plurality of drivers, for example, using an IC card, and acquires tachometer information via the IC card. Although described assuming a case, this speed warning device A is not limited to an application limited to individual drivers, and a plurality of drivers can use the same vehicle by using an excess position of the observing speed common to individual vehicles. It is also applicable when using.
