Description

  The present invention relates to an alarm device mounted on a vehicle.

  Conventionally, on-board devices such as digital tachographs and drive recorders have previously registered hazardous locations as hazard map data using GPS (Global Positioning System) location information, and when a vehicle approaches that location, an alarm is issued. There was something to encourage.

  As this type of prior art, only data existing on an operation route is extracted from danger point data necessary for a warning to a driver, stored in a memory card, and the memory card is mounted on a drive recorder. Thus, a technique for significantly reducing the data amount is known (see Patent Document 1).

  Further, an on-vehicle device (radar detector) in which a sudden braking occurrence point warning function is added to a GPS warning function is known (see Patent Document 2). The vehicle-mounted device stores a point at which a sudden change in speed is stored as a sudden braking occurrence point, and issues an alarm when the vehicle approaches the point next time.

(First embodiment)

  FIG. 1 is a block diagram showing a configuration of a digital tachograph 10 according to the embodiment. The digital tachograph 10 includes a CPU 11, a memory 26, a recording unit 17, a card I / F 18, an audio I / F 19, an RTC (clock IC) 21, a SW input unit 22, a display controller 23, and an LED display unit 27.

  The CPU 11 controls the entire digital tachograph 10. The memory 26 stores an operation program executed by the CPU 11 and the like. The memory 26 stores an operation schedule acquired from a memory card 55 or an office PC (not shown) by communication. The operation schedule includes the location information (latitude and longitude) of the area where the vehicle normally travels and the travel route, the operation time, and the like. In the memory 26, a hazard map table 43 (position registration unit, alert data registration unit) to be described later is registered.

  The recording unit 17 records operation data including the driving state of the vehicle and GPS position information in a time-series manner. A memory card 55 carried by a crew is detachably attached to the card I / F 18. A microphone 29 and a built-in speaker 20 are connected to the audio I / F 19. The RTC 21 measures the current time and also functions as a timer. Operation input (ON / OFF) signals of various buttons including the exit button are input to the SW input unit 22. The display controller 23 controls display on a display 28 connected to the outside. The LED display unit 27 displays the status of communication and operation.

  Further, the digital tachograph 10 includes a speed I / F 12A, an engine rotation I / F 12B, an external input I / F 13, a sensor input I / F 14, a GPS receiving unit 15, a CAN_I / F 16, a communication unit 24, and a power supply unit 25.

  A speed pulse representing the speed of the vehicle is input to the speed I / F 12A from the vehicle speed sensor. When the CPU 11 detects a speed from a speed pulse input via the speed I / F 12A, the CPU 11 and the speed I / F 12A correspond to an operation state detection unit. A rotation pulse representing the engine speed is input from the engine speed sensor to the engine speed I / F 12B. Various external devices are connected to the external input I / F 13. Here, as an external device, a vehicle-mounted camera 71 or the like is connected to the external input I / F 13, and various types of information including a captured image are input.

  The sensor input I / F 14 includes a temperature sensor for detecting an engine temperature (cooling water temperature), a fuel sensor for detecting a fuel amount, and a brake for detecting on / off of a brake and outputting a brake signal when the brake is on. A switch (SW) detects the on / off of the turn signal, and when the turn signal is on, a turn signal SW or the like that outputs a turn signal is connected, and various information is input.

  The GPS receiving unit 15 (position detecting unit) is connected to the GPS antenna 15a and acquires a current position (GPS position information). The GPS position information (latitude, longitude) acquired by the GPS receiving unit 15 is recorded in the recording unit 17 in chronological order. Various devices in the vehicle connected to a CAN (Controller Area Network) standard network are connected to the CAN_I / F 16 to enable communication of various data such as speed, engine, and fuel amount. The communication unit 24 performs wide-area communication via a wide-area communication network such as a wireless communication line (for example, 3G line / LTE) and a packet communication network such as the Internet.

  The power supply unit 25 is connected to a battery via an ignition switch (SW), and supplies power to each unit of the digital tachograph 10 when power is supplied from the battery when the ignition SW is turned on.

  FIG. 2 is a diagram showing registered contents of the hazard map table 43. This hazard map table 43 is stored in the memory 26. Further, the hazard map table 43 registers, for each point (GPS position information) to be driven with caution, voice data (phrase) of an alarm corresponding to a condition that an external signal and a speed that are operating parameters match. I have.

  Specifically, at the temporary stop point (point a), voice data of a normal warning, for example, voice data of “approaching a traffic accident frequent spot”, which is generated when the brake signal is on, is registered. Also, voice data of a high-risk alarm (alarm A), which is generated when the brake signal is off, for example, voice data (phrase) of "Please decelerate. Pause in the future."

  Further, at the pause point (point a), voice data of a normal warning that is sounded when the speed (vehicle speed) is 0 (km / h), for example, "Let's proceed after checking the left and right enough." Is registered. Also, voice data of a high-risk warning (alarm B), for example, voice data of "Dangerous. Please pause.", Which is generated when the speed is not 0 (km / h), is registered. In this way, even if the vehicle decelerates, the sound data of the alarm that is sounded depending on whether the vehicle speed actually becomes 0 (km / h) is made different.

  Further, at the T-shaped intersection point (point c), voice data of a normal warning, for example, voice data of "approaching a traffic accident occurrence point", which is generated when there is a turn signal, is registered. In addition, voice data of a high-risk alarm (alarm C) which is sounded when there is no blinker signal, for example, voice data of "It is dangerous. Please give a blinker."

  At the intersection point (point d), when the vehicle speed is lower than the set speed (for example, 20 km / h), normal voice data, for example, voice data of "Let's proceed carefully with oncoming traffic." Is done. When the vehicle speed is equal to or higher than the set speed, voice data of a high-risk warning (alarm D), for example, voice data of “It is dangerous. Please reduce the speed.” Is registered.

  The alarm operation of the digital tachograph 10 having the above configuration is shown. FIG. 3 is a flowchart showing the alarm operation procedure. This operation program is stored in the memory 26 in the digital tachograph 10, and is executed by the CPU 11.

  The CPU 11 determines whether or not the GPS position information (latitude, longitude) obtained by the GPS receiving unit (GPS module) 15 is being measured (S1). If the positioning is not being performed, the CPU 11 repeats the process of step S1.

  On the other hand, when positioning is being performed, the CPU 11 determines whether or not the obtained GPS position information (latitude, longitude) is a position (registered position) registered in the hazard map table 43 (S2). If it is not the registered position, the CPU 11 returns to the processing of step S1.

  On the other hand, when the GPS position information (latitude and longitude) is the registered position, the CPU 11 determines whether the GPS position information is approaching the pause point (S3). When it is determined that the vehicle is approaching, the CPU 11 determines whether or not the brake SW is operated and a brake signal is input (detected) via the sensor input I / F 14 (S4). When the brake signal is detected, the CPU 11 reads out the voice data of “The vehicle is approaching a frequent traffic accident point” corresponding to the normal warning registered in the hazard map table 43, and reads the voice data from the speaker 20. (S5).

  When the brake signal is not detected, the CPU 11 generates an alarm A (S6). That is, the CPU 11 reads out the voice data of “Please decelerate. Pause in the future.” Corresponding to the alarm A, which is registered in the memory 26 and the hazard map table 43, and read the voice data from the speaker 20. To output the sound.

  After generating the alarm A, or after generating the normal alarm in step S5, the CPU 11 activates the RTC 21 and starts timer measurement (S7). The CPU 11 determines whether the speed 0 (km / h) is detected from the speed pulse input via the speed I / F 12A (S8). When the speed 0 (km / h) is detected, the CPU 11 proceeds to the process of step S15, reads out the voice data of “Let's proceed after checking left and right enough” corresponding to the normal alarm from the memory 26, and 20 outputs the sound based on the sound data. Thereafter, the CPU 11 returns to the processing of step S1.

  On the other hand, if the speed 0 (km / h) is not detected in step S8, the CPU 11 determines whether the timer time measured by the RTC 21 has passed a predetermined time T seconds (S9). T seconds is set to an approximate value at which the vehicle is normally expected to stop after a brake operation. If the predetermined time T seconds has not elapsed, the CPU 11 returns to the process of step S8.

  On the other hand, when the predetermined time T seconds has elapsed, the CPU 11 generates an alarm B (S10). That is, the CPU 11 reads out the voice data of “Danger. Pause.” Corresponding to the alarm B registered in the hazard map table 43 registered in the memory 26, and reads out the voice data from the speaker 20. Make sound output. Thereafter, the CPU 11 returns to the processing of step S1.

  On the other hand, if the GPS position information is not approaching the pause point in step S3, the CPU 11 determines whether the GPS position information is approaching the intersection point (S11). If the vehicle is approaching the intersection point, the CPU 11 determines whether there is a blinker signal obtained from the blinker SW via the sensor input I / F 14 (S12).

  If there is a turn signal, the CPU 11 determines whether the current speed obtained from the speed pulse input via the speed I / F 12A is equal to or higher than a set speed (for example, 20 km / h) (S13). If the speed is equal to or higher than the set speed, the CPU 11 generates an alarm D (S14). That is, the CPU 11 reads out the voice data of “Dangerous. Please reduce the speed.” Corresponding to the alarm D registered in the hazard map table 43 registered in the memory 26 and read out the voice data from the speaker 20. Make sound output. Thereafter, the CPU 11 returns to the processing of step S1.

  On the other hand, if the current speed is lower than the set speed in step S13, the CPU 11 proceeds to the process in step S15, and reads out the voice data of "Let's proceed with caution to oncoming vehicles." Then, the sound based on the sound data is output from the speaker 20. Thereafter, the CPU 11 returns to the processing of step S1.

  If there is no blinker signal in step S12, the CPU 11 proceeds to the process in step S15, reads out voice data of "approaching a traffic accident frequently occurring point" corresponding to the normal warning from the memory 26, and reads out the voice data from the speaker 20. Outputs audio based on audio data. Thereafter, the CPU 11 returns to the processing of step S1.

  On the other hand, when the GPS position information is not approaching the intersection point in step S11, the CPU 11 determines whether the GPS position information is approaching the T-shaped intersection point (S16). If the vehicle is not approaching the T-shaped intersection point, the CPU 11 returns to the process of step S1.

  On the other hand, when approaching the T-shaped intersection point, the CPU 11 determines whether there is a turn signal or not (S17). If there is no blinker signal, the CPU 11 generates an alarm C (S18). That is, the CPU 11 reads out the sound data of “It is dangerous. Please turn on the blinker.” Corresponding to the alarm C registered in the memory 26 and the hazard map table 43, and read out the sound data from the speaker 20. Make sound output. Thereafter, the CPU 11 returns to the processing of step S1.

  On the other hand, if there is a blinker signal in step S17, the CPU 11 proceeds to the process in step S15, reads out the voice data of “The vehicle is approaching a traffic accident frequent spot” corresponding to the normal alarm from the memory 26, and reads out the voice data from the speaker 20. The sound based on the sound data is output. Thereafter, the CPU 11 returns to the processing of step S1.

  FIGS. 4A and 4B are diagrams showing a warning at a temporary stop point (point a). When the vehicle 8 approaches the pause point (point a), that is, when the vehicle 8 enters an outer circle (outer circle) 53 which is a region centered on point a, the driver, as shown in FIG. Is stepping on the brake, the digital tachograph 10 determines that there is a brake signal. In this case, the digital tachograph 10 emits a sound of “You are approaching a traffic accident frequent spot” from the speaker 20 as a normal alarm.

  On the other hand, as shown in FIG. 4 (B), when the vehicle 8 enters the outer circle 53 set at the temporary stop point (point a) and there is no brake signal, the digital tachograph 10 As a high-level alarm, the following sound is generated: "Please slow down. Pause in the future."

  FIGS. 4C and 4D are diagrams showing further warnings at the suspension point (point a). If the speed 0 (km / h) is detected within a predetermined time T seconds after the vehicle 8 enters the outer circle 53 and then enters the circle (inner circle) 51 set further inside, the digital tachograph 10 As shown in FIG. 4 (C), the speaker 20 generates a normal warning sound, "Let's proceed after checking left and right enough."

  On the other hand, as shown in FIG. 4 (D), when the speed 0 (km / h) is not detected within a predetermined time T seconds after the vehicle 8 enters the inner circle 51, the digital tachograph 10 As a high-level alarm, the sound "Dangerous. Please pause."

  FIGS. 5A and 5B show a warning at a T-shaped intersection point (point c). When the vehicle 8 approaches the T-shaped intersection point (point c), that is, when the vehicle 8 enters a circle 56 centered at point c, as shown in FIG. Causes the speaker 20 to generate a normal warning sound of "You are approaching a point where traffic accidents frequently occur."

  On the other hand, as shown in FIG. 5 (B), when the vehicle 8 enters the circle 56 and there is no blinker signal, the digital tachograph 10 outputs a high-risk warning from the speaker 20 as "Dangerous. Please sound. "

  FIGS. 5C and 5D are diagrams showing a warning at an intersection point (point d). When the vehicle 8 approaches the intersection point (point d), that is, when the vehicle 8 enters a circle 58 centered at point d, as shown in FIG. 5C, there is a turn signal and the vehicle speed is lower than the set speed. In such a case, the digital tachograph 10 generates a sound of “Let's proceed with caution to oncoming vehicles.” As a normal warning from the speaker 20.

  On the other hand, as shown in FIG. 5 (D), when the vehicle 8 enters the circle 58 and the turn signal is present, but the vehicle speed is higher than the set speed, the digital tachograph 10 outputs a high-risk alarm from the speaker 20. , "Dangerous, slow down."

  As described above, the digital tachograph 10 registers the position information as the place to be driven with caution in the hazard map table 43 in the memory 26. The digital tachograph 10 detects a driving state due to a driver's driving operation when the vehicle 8 approaches a place to be driven with caution, and when it is determined that the degree of danger is high, an alarm indicating a high degree of danger from the speaker 20. Emits. At this time, when the driver knows that the warning issued from the speaker 20 is a warning with a high degree of danger unlike normal driving, the driver notices an error in his driving operation. As a result, it is expected that the driver will observe safe driving.

Therefore, by registering the place to be driven carefully as position information, the driver can be alert to the driving operation without getting used to the warning no matter how many times the vehicle passes through the place to be careful. Can be encouraged. Further, since the operating state is determined by a plurality of operating parameters (speed, brake on / off, turn signal on / off), an appropriate alarm corresponding to the operating state can be generated.
(Modification)

  In the first embodiment, at the temporary stop point, the determination as to whether to issue a high-risk alarm is performed twice, and an alarm is issued using different voice data in each case. An alarm may be issued only by the judgment.

In addition, a common voice data may be used for a high-risk warning at the temporary stop point, or different voice data may be used for each registered point. That is, even at the same pause point, the sound data to be pronounced may be different at each point. In this case, the data amount of the audio data to be registered is expected to be enormous, but in order to reduce the data amount of the audio data to be registered, many registration points are classified into groups, and each group is used for an alarm. Voice data may be shared and registered. For example, when almost the same road condition is assumed, an alarm may be issued at these suspension points using the same audio data.
(Second embodiment)

  In the first embodiment, the voice data at the point registered as the place to be driven with caution is changed based on the driving state of the vehicle. However, in the second embodiment, the external information of the vehicle (the external information of the vehicle) is changed. In this case, the voice data at a point registered as a place to be driven with caution is changed in consideration of the above situation.

  The digital tachograph of the second embodiment has almost the same configuration as that of the first embodiment. Therefore, the same reference numerals are used for the same components as those of the first embodiment, and the description thereof will be omitted. I do.

  In the second embodiment, the digital tachograph 10 analyzes a captured image input from the in-vehicle camera 71 (external situation detection unit) such as a drive recorder, which is input via the external input I / F 13, and the analysis result Is added to the high-risk alarm.

  Further, the acquisition and analysis of the captured image are performed, for example, after the temporary stop point, the intersection point, and the T-shaped intersection point are determined in steps S3, S11, and S16 in FIG. 3 in the first embodiment, respectively. You may. That is, at this timing, the digital tachograph may capture an image of the outside of the vehicle with the on-board camera and analyze the captured image.

  FIG. 6 is a diagram illustrating an image captured by the vehicle-mounted camera 71 according to the second embodiment. By the image recognition processing, for example, the following road conditions are assumed. FIG. 6A shows an image in which the color of the traffic light at the intersection point is lit in yellow. In this case, for the driver, as an alarm having a high degree of danger, for example, voice data of "Please note that the traffic light turns red, so be careful." FIG. 6B shows an image in which there are large trees beside the road at the intersection and visibility is poor. In this case, as a warning with a high degree of danger to the driver, in addition to the above-described warning, for example, voice data of “Please be careful because the visibility is poor” is added.

  In addition, when there is a person waiting to cross on the side of the road at the T-junction point, in addition to the above-mentioned warning as a high-risk warning, for example, "Be careful because there are people trying to cross. Please. "May be added.

  These audio data may be registered in the hazard map table 43 stored in the memory 26, or may be registered in another storage area, as in the first embodiment.

  In this way, in consideration of the driving state of the vehicle as well as the external situation of the vehicle, voice data may be selected and a high-risk warning may be issued, and a warning more suitable for road conditions may be issued. The driver can be more appropriately alerted. That is, an appropriate warning reflecting the situation outside the vehicle can be issued.

  Although an image of the outside of the vehicle captured by an on-board camera such as a drive recorder is shown here for detecting a situation outside the vehicle, regardless of the captured image, a raindrop attached to a hood or the like of the vehicle is provided. A sensor may be used. In this case, when the rain sensor detects rain (the rain is falling), the digital tachograph is running in rainy weather. Can be.

  Note that the technical scope of the present invention is not limited to the above embodiment. The embodiments described above can be accompanied by various modifications and improvements without departing from the technical scope of the present invention.

  For example, in the above-described embodiment, the case where the alarm device is applied to an in-vehicle device mounted on a vehicle has been described. However, the alarm device may be applied to a portable device such as a smartphone or a tablet terminal carried by a driver or the like. Further, the vehicle-mounted device is not limited to a digital tachograph, and may be applied to a drive recorder, a car navigation device, a meter device, and the like.

  Further, in the above embodiment, when an alarm is generated, only a sound is output from the speaker. However, an image indicating the alarm may be displayed on a screen of a display device such as an LCD or a head-up display. The output and the display of the alarm image on the display may be performed together.

Further, in the above-described embodiment, the voice data is uniquely selected from the position information and the driving state, but a plurality of voice data that match the same position information and the same driving state condition are registered, When the above condition is met, voice data may be selected periodically or randomly from the plurality of voice data, and a high risk alarm may be issued. This can further reduce the driver's familiarity with the alarm.
