  Next, the form for implementing this invention is demonstrated using an Example.

  FIG. 1 is a block diagram showing an outline of a configuration of a warning notification device 10 as an embodiment of the present invention. As shown in the figure, a warning notification device 10 according to an embodiment includes a microcomputer 20 that inputs signals from various sensors of a vehicle and sets warnings for passengers, and a display that displays icons and warning messages associated with warning contents. 30 and a sounding buzzer 40 for sounding a warning sound to the occupant.

  The microcomputer 20 is configured as a control unit that performs control for notifying an occupant of a warning centering on the CPU 22, and in addition to the CPU 22, a memory 24 that stores a processing program and temporarily stores data, A timer 26 for executing time measurement processing according to a time measurement command, an input / output port (not shown), and the like are provided. Signals from various sensors provided in the vehicle are input to the microcomputer 20 via the input port, and a signal for notifying a warning is transmitted to the display 30 and the sounding buzzer 40 via the output port. Here, as signals from various sensors provided in the vehicle, for example, a vehicle speed signal from a vehicle speed sensor for detecting the vehicle speed, a signal indicating whether or not the parking brake is locked, and a seat belt are worn. A signal indicating whether or not the airbag device is normal, a signal indicating whether or not the headlight is turned on, and whether the ignition (IGN) switch is on or off , A signal indicating the open / closed state of the door, a signal indicating the remaining amount of gasoline in the gasoline tank, an engine abnormality signal from a diagnosis device (not shown) for determining engine abnormality, and the like. As a signal from such a sensor, it is sufficient that a signal necessary for notifying an occupant is input, and only a part of these signals are input, or in addition to these signals, Other signals may be input.

  The display 30 is configured as a liquid crystal display using a thin film transistor, for example, and is disposed in the vehicle so that at least the driver can see the display 30. The display 30 displays icons and warning messages reminiscent of various warning targets in response to signals from the microcomputer 20. Similarly, the sounding buzzer 40 sounds a warning sound to the passengers in the vehicle according to the signal from the microcomputer 20.

  Next, warning notification by the warning notification device 10 of the embodiment configured as described above will be described. FIG. 2 is a flowchart illustrating an example of a warning notification routine that is executed by the CPU 22 of the microcomputer 20 according to the embodiment in accordance with a program recorded in the memory 24. This routine is repeatedly executed when the vehicle system is activated.

  When the warning notification routine is executed, the CPU 22 of the microcomputer 20 first selects a warning determination target as a target for determining whether or not to notify the warning (step S100), and warns the selected warning determination target. Is determined (step S110), and when a warning subject to warning determination is not required (step S120; NO), the warning notification routine is terminated without warning notification using the display 30 or the buzzer 40. Here, examples of the warning determination target include a parking brake, a seat belt, an air bag device, a headlight, a gasoline remaining amount in the gasoline tank, an engine abnormality, and the like, which are sequentially selected in a predetermined order. Can be things. Further, as the determination of the necessity of warning, for example, when a seat belt is selected as a warning determination target, a signal indicating whether the seat belt is worn or a vehicle speed signal is input and the seat belt is not worn. When the vehicle speed reaches a predetermined vehicle speed (for example, several km / h) or more, it is determined that it is necessary to notify the occupant of a warning. When a headlight is selected as a warning determination target, the headlight is turned on. A signal indicating whether the IGN switch is on or off, a signal indicating the door open / closed state, and the door is opened with the engine stopped and the door open. If it is determined that it is necessary to notify the occupant of a warning when is lit, and an engine abnormality is selected as the warning determination target, Time abnormality signal of the engine from the Shisu device predetermined (e.g., several seconds) can be made to determine that it is necessary to inform a warning to the occupant when entered over. Various methods may be used for the determination of the warning determination target and the necessity of the warning, and the determination of the warning determination target and the necessity of the warning itself does not form the core of the present invention, and thus more detailed. Description is omitted.

  When it is determined in step S110 that a warning subject to warning determination is necessary (step S120; YES), it is determined whether or not the warning subject to warning determination is performed for the first time (step S130). (Step S130; YES), the timer 24 starts measuring the warning duration time t (Step S140). That is, when it is determined that the warning subject to warning judgment is not necessary in this routine last time and this warning judgment target warning is judged to be necessary this time, the timer 24 starts the timing process, and the duration of the warning state The warning continuation time t is measured. If this warning determination target warning state is not resolved next time (step S120; YES, step S130; NO), the timer 24 continues to count the warning continuation time t, and the process of step S150 is continued. Proceed to

  Subsequently, a warning opportunity is set based on a warning determination target that needs a warning and the warning duration t (step S150), and whether or not a warning is to be notified is determined based on the set warning opportunity ( If the warning is not notified (step S160) (step S160; NO), this routine is finished as it is. In the embodiment, when a warning subject to warning determination is necessary, the warning is periodically notified over a predetermined warning notification time in order to notify the passenger without feeling troublesome. In the warning notification device 10 according to the embodiment, the longer the warning duration t, which is the duration of the warning state, is, the greater the number of opportunities for warnings to be urged to effectively eliminate the warning from the occupant. Set warning opportunities. As the setting of the warning opportunity, a notification time setting map in which the relationship between the warning notification time, the warning determination target, and the warning continuation time t is determined in advance is stored in the memory 24, and the warning determination target, the warning continuation time t, Is set by deriving and setting a corresponding warning notification time from a stored map, or a notification cycle setting map in which a relationship between a notification cycle for warning notification, a warning determination target, and a warning duration time t is determined in advance. Can be stored in the memory 24, and when a warning determination target and a warning duration t are given, a corresponding notification cycle can be derived and set from the stored map. FIG. 3 shows an example of the notification time setting map, and FIG. 4 shows an example of the notification period setting map. By setting the warning opportunity based on the warning duration time t in this way, it is possible to prevent the passenger from feeling troubled by the warning notification, and compared to the case where the warning is notified at a uniform warning opportunity. This effectively urges the passenger to cancel the warning state.

  When notifying a warning (step S160; YES), it is determined whether or not a warning is required for a predetermined warning determination target in addition to the warning determination target currently selected in step S100 (step S170). When no warning is required for a predetermined warning determination target (step S170; NO), the warning display content is set based on the warning duration t (step S180). In this case, the warning display content is set by previously storing the relationship between the warning determination target, the warning duration t and the warning display content in the memory 24 as a table, and the warning determination target and the warning duration t are given. From the stored table, the corresponding warning display content is derived and set. Specific examples are shown below. FIG. 5 shows an example of the warning display content when the warning duration t is relatively short for the headlight, and FIG. 6 shows an example of the warning display content when the warning duration t is relatively long for the headlight. When it is determined that the headlight remains on with the engine stopped and the door opened, and a warning is required for the occupant, first, as shown in FIG. 32 and an explanatory note 34 explaining the warning state are set as warning display contents. Then, when the warning duration t becomes longer without turning off the headlight (for example, when a predetermined time (tens of seconds, etc.) is exceeded), as shown in FIG. In addition to 34, a message 36 for notifying that the battery may run out due to the headlight not being turned off is set as the warning display content.

  FIG. 7 to FIG. 9 show examples of warning display contents for seat belts. When it is determined that the occupant needs to be warned because the vehicle speed reaches a predetermined vehicle speed or more without wearing the seat belt, first, as shown in FIG. The sentence 34 is set as the warning display content, and when the warning continuation time t becomes longer without wearing the seat belt, subsequently, as shown in FIG. If the warning 36 is set to the warning display content and the warning duration t is increased without wearing the seat belt, the seat belt A message 36 that informs passengers of the damage that may be caused by not being worn (in the example of FIG. 9, the damage at the time of the accident increases) It is set to display the contents.

  Furthermore, FIG. 10 and FIG. 11 show examples of warning display contents when engine oil pressure is insufficient as an engine abnormality. When a signal is input for a predetermined time (for example, several seconds) when the oil pressure of engine oil is insufficient from a diagnosis device (not shown), first, an icon reminiscent of a warning state as shown in FIG. 32 and an explanatory note 34 explaining the warning state, and a message 36 for notifying the damage that may be caused to the vehicle due to insufficient oil pressure of the engine oil (in the example of FIG. 10, this may cause engine damage such as burn-in). )) Is set as the warning display content, and if the warning continuation time t becomes long without the lack of engine oil pressure being resolved, a message that more greatly informs the possible damage to the vehicle than when the warning continuation time t is short 36 (the possibility that the engine may be damaged and cannot be run) is set as the warning display content. Thus, by setting the warning display content according to the warning duration time t, it is possible to effectively promote the cancellation of the warning state as compared with the case where the warning display content is uniformly set.

  When the warning display content is set in this way, subsequently, a warning sound is set based on the warning duration time t (step S200), the warning display content is transmitted to the display 30 and the warning sound is transmitted to the blowing buzzer 40. (Step S210), the warning notification routine is terminated. The display 30 that has received the warning display content displays the warning display content, and the sounding buzzer 40 that has received the warning sound emits a warning sound. Here, as the setting of the warning sound, for example, the volume is increased, the sound is increased, or the warning sound is increased so that the occupant feels the warning sound more prominently as the warning duration t is longer. It is possible to shorten the cycle of sounding. Thus, by setting the warning sound based on the warning duration t and notifying the occupant, it is possible to effectively cancel the warning state as compared with the case where the warning sound is uniformly set and notified to the occupant. Can be urged.

  When it is determined that a warning is required for a plurality of warning determination targets in a predetermined combination and a warning is required for a predetermined warning determination target in addition to the currently selected warning determination target (step S170; YES), The warning display content is set so that a problem that may occur due to a plurality of warning states is notified (step S190), and a warning sound is set in the same manner as when the warning state is single (step S200). Is transmitted to the display 30 and the warning sound is transmitted to the sounding buzzer 40 (step S210), and the warning notification routine is terminated. After the end, the warning notification routine is resumed by the microcomputer 20 again. In this case, the warning display content is set by previously storing a plurality of warning determination targets in the warning state and the relationship between the warning duration t and the warning display content in the memory 24 in advance as a table. When the warning duration t is given, the corresponding warning display content is derived from the stored table and set. As an example when a plurality of warning states occur, FIGS. 12 and 13 show examples of warning display contents when both the seat belt and the airbag apparatus need to be warned. When the air bag device needs to be stopped and inspected, and when the vehicle speed reaches a predetermined vehicle speed without wearing the seat belt, as shown in FIG. 12, the respective warning states of the seat belt and the air bag device In addition to the icon 32 reminiscent of the warning and the explanatory note 34 for explaining the respective warning states, a message 36 of a malfunction that may occur because both the seat belt and the airbag device are in the warning state (in the example of FIG. When an accident occurs, the head may be smashed) is set as a warning display content, and when this state continues and the warning duration t becomes longer, a message is displayed as shown in FIG. 36 is changed (in the example of FIG. 13, the driver is likely to be thrown out of the vehicle when a traffic accident occurs), and the warning display content is set. As described above, when a plurality of warning states are overlapped, it is possible to effectively prompt the occupant to cancel the warning state by notifying the occupant of a problem that may occur due to the plurality of warning states. In addition, the warning display content is set based on the warning continuation time t in the same way as when the warning status is single, so that the warning state can be resolved to the occupant compared to the case where the warning display content is set uniformly. It can be promoted effectively.

  In the warning notification device 10 according to the embodiment described above, one or more warning messages (descriptions 34 and messages 36 explaining the contents of the warning state) are selected and the warning display contents are set according to the duration of the warning state. Therefore, the warning display content can be changed according to the duration of the warning state, and the warning state can be more effectively urged to be resolved compared to the case where the warning display content is uniformly set. Can be suppressed. In addition, when a plurality of warning states are overlapped, a message 36 indicating a problem that may occur due to a plurality of warning states is set as warning display contents and a warning is notified to the occupant. It is possible to suppress the warning state from continuing.

  In the warning notification device 10 of the embodiment, the warning display content is set according to the warning duration time t, and when a plurality of warning states are overlapped, a malfunction that may be caused by a plurality of warning states is set as the warning display content. However, only one of them may be adopted. That is, when a plurality of warning states are overlapped, warning messages are set for each warning state according to the warning duration t, and the set warning messages are displayed on the display 30 simultaneously or sequentially. It is good. Further, as long as a problem that may occur due to overlapping of a plurality of warning states is set in the warning display content, the warning display content may be set regardless of the warning duration time t.

  In the warning notification device 10 according to the embodiment, the message 36 is set as the warning display content in addition to the warning description 34, but one of the description 34 and the message 36 is set according to the warning duration t. The warning display content may be set. In the embodiment, the message 36 is changed from the content indicating that the warning state violates the law to the content indicating vehicle damage or passenger damage that may occur due to the warning state in accordance with the warning duration t. However, it may be changed from contents indicating vehicle damage or occupant damage caused by the warning condition to contents indicating that the warning condition violates laws and regulations, and the warning duration t becomes longer. Both may be set as warning display contents. In addition, the warning duration may be a message explaining the warning status, a message indicating that the warning status violates the law, a message indicating vehicle damage or passenger damage that may occur due to the warning status, etc. It is also possible to change and set in order according to t. Even in these cases, it is possible to effectively prompt the occupant to cancel the warning state.

  In the warning notification device 10 of the embodiment, the warning opportunity is set based on the warning duration t, but the predetermined time (for example, every several tens of seconds) regardless of the warning duration t. For example, the warning display content may be displayed on the display 30 for several seconds. Further, at least a part of the warning display content may be continuously displayed on the display 30.

  In the warning notification device 10 of the embodiment, the warning sound is set based on the warning duration t, but the predetermined time (for example, every several tens of seconds) regardless of the warning duration t. For example, a warning sound may be sounded from the sounding buzzer 40 for several seconds. In addition, the warning notification device 10 may notify the passenger of a warning without using a warning sound.

  In the warning notification device 10 of the embodiment, the warning notification device 10 has been described as including the display 30 and the buzzer 40. However, the warning display content is transmitted to the display mounted on the vehicle to notify the occupant of the warning. The warning sound may be transmitted to an acoustic system or the like mounted on the vehicle to notify the occupant of the warning. In the embodiment, the warning notification device 10 is applied to a vehicle. However, the warning notification device may be applied to a vehicle other than the vehicle such as a ship or an airplane. The program may be recorded in a predetermined storage medium and installed in the warning notification device 10 (computer), or may be supplied to the warning notification device 10 (computer) via a network such as the Internet. .

  The embodiments of the present invention have been described above using the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention. Needless to say.

  The present invention can be used in the manufacturing industry of warning devices for vehicles.
