Description

Technical area

[0001] The present invention relates to an on-board warning system mounted in a motor vehicle. State of the art

[0002] Conventionally, a warning system is mounted in a motor vehicle to monitor target objects such as doors, seat belts, and windows for monitoring aspects such as unfastened seat belts, partially closed doors, and open windows. Then, when the thus monitored devices satisfy predetermined conditions, whereby it is determined that an occupant or occupants of the motor vehicle need to be warned of impending or potential hazards caused by unfastened seat belts, partially closed doors, and open windows, the warning system issues appropriate warnings to the occupants. The warnings issued by the warning system are provided by the illumination of warning lights provided on an instrument cluster installed in an instrument panel or a display located in an upper portion of a windshield.

[0003] Furthermore, in a cabin of a passenger aircraft, as a means of transport other than a motor vehicle, seat belt buckle warning lights on passenger seats are provided and are illuminated to provide warnings to seated passengers when the aircraft takes off or lands.

[0004] As a relevant prior art in this field, a seat belt warning system is known in which, when it is determined that although seat sensors detect that passengers are sitting in seats and the fastening of the seat belts has not yet been detected, so that the passenger in a respective seat has not yet fastened the seat belt, an ECU issues warnings to the passengers by a light signal (see Patent Literature 1). Patent literature

[0005] [Patent Document 1]: JP 2014-151727 A

[0006] Further prior art is known from the documents DE 10 2006 042 299 A1, US 5 555 458 A, US 8 005 595 B2, DE 10 2004 041 402 A1, US 8 220 579 B2, DE 102 03 139 A1 and DE 10 2009 034 919 A1. Overview of the invention Problem to be solved by the invention

[0007] However, in the conventional warning system, the warning lights that issue corresponding warnings related to the monitoring targets are arranged near a driver's seat, and therefore, it is difficult for the occupants not sitting in the driver's seat to recognize that the warnings are being issued. This prompts the driver to take action to avoid the situation for which the warnings are issued by announcing the issuance of the warnings to the occupants. That is, the driver asks the occupants to fasten their seat belts, close the partially closed doors, or close the open windows. Furthermore, there has been a problem in that even though a light is issued to the occupant for warning, if the occupant is not looking at the source of the emitted light, the occupant is unaware of the warning.

[0008] If a warning is issued within the cabin of a passenger aircraft, the pilot will activate the seat belt warning lights regardless of whether the seat belts are fastened. Consequently, the warning lights will be activated even for passengers who have already fastened their seat belts. Furthermore, even if the passengers have fastened their seat belts, the warning lights will remain illuminated until the pilot deactivates them.

[0009] Therefore, in the conventional warning system, it has been difficult for occupants seated in seats away from the driver's seat to be directly warned about the monitoring targets. There has been a problem in that it is highly likely that the occupants partially seated in the rear seats were unaware of the issued warnings. The invention was conceived to solve the problem inherent in the conventional technology, and its object is to provide an in-vehicle warning system in which an occupant who is to perform an operation to cancel the warning can be directly warned, even if the occupant is seated in any provided seat, when a danger occurs that requires issuance of a warning about at least one of the monitoring targets. [Means of solving the problem] (1) In order to achieve the above-described object, the on-board warning system of the present invention is characterized by the features of claim 1. (2) The on-board warning system referred to in (1), which further comprises: Occupant detection modules for detecting that the occupants are sitting in the seats, wherein the control module turns on the warning lights when it is detected that the occupants are sitting in the seats and it is determined that the conditions of the monitoring targets in the seats have reached the warning level. (3) The on-board warning system according to (1) or (2), wherein the control module switches off the warning lamps after a certain period of time when the conditions corresponding to the warning level are cancelled. (4) The on-board warning system according to (1) or (2), wherein the control module turns off the warning lights when a predetermined signal is detected depending on a starting operation for starting the vehicle by the driver when the conditions corresponding to the warning level are canceled. (5) The on-board warning system according to any one of (1) to (4), further comprising: a display arranged near a driver's seat for displaying a position of the seat corresponding to the warning lamp being illuminated and for displaying details of the warnings issued by the warning lamp in an associated manner. (6) The on-board warning system according to one of (1) to (5), the warning lights corresponding to the rear seats are arranged in a ceiling of the vehicle. (7) The on-board warning system according to one of (1) to (6), wherein the warning level condition includes a condition of an unfastened seat belt and / or a door and / or a window that is not fully closed.

[0010] The on-board warning system configured as described in (1) above can, when it detects that the state of at least one of the monitoring targets has reached the warning level at which a warning is to be issued, issue a warning directly to the occupant sitting in the seat near the warning monitoring target. This makes the occupant sitting in the seat in question aware that the warning is being issued, making it possible to force the occupant to take an action to cancel the warning immediately, without being instructed to do so by the driver.

[0011] According to the on-board warning system constructed as described in (2), since the seat sensors individually provided in the seats detect that the occupants are sitting in the seats, the warning can be issued more accurately by linking the detection of the occupants with the occurrence of the warnings. Consequently, no unnecessary warning is issued, resulting in electrical energy savings.

[0012] According to the on-board warning system constructed as described in (3), the warning lights can be prevented from remaining on unnecessarily.

[0013] According to the on-board warning system constructed as described in (4), the warning lights can be prevented from remaining on unnecessarily.

[0014] According to the on-board warning system constructed as described in (5), since the same warning as the warning issued for the seat other than the driver's seat is also issued from the display arranged near the driver's seat, the driver can easily determine whether he or she is allowed to drive the vehicle.

[0015] According to the on-board warning system constructed as described in (6), since the warning lights are provided in the ceiling, it is possible to use general ceiling-mounted lights as warning lights, thereby improving the flexibility of use.

[0016] According to the on-board warning system constructed as described in (7), if the monitoring target is an unfastened seat belt, it is possible to prompt the occupant to fasten the seat belt. Furthermore, if the monitoring target is a door that is not completely closed, it is possible to prompt the occupant to close the door completely. Furthermore, if the monitoring target is an open window, it is possible to prompt the occupant to close the window.

[0017] According to the on-board warning system of the invention, occupants can identify the monitoring targets from the colors of the warning lights when they illuminate. Consequently, occupants can initiate the appropriate remediation process to immediately cancel the warnings. Advantages of the invention

[0018] According to the invention, a warning can be issued directly to the occupant seated in the seat closest to the warning-generating monitoring target when the state of at least one of the monitoring targets has reached the warning level at which a warning is to be issued. This causes the occupant seated in the seat in question to be informed of the warning, making it possible to force the occupant to take the necessary action to immediately cancel the warning.

[0019] This briefly describes the invention. The invention will be explained in greater detail by specifying the mode of carrying out the invention (hereinafter referred to simply as an "embodiment"), which is described below with reference to the accompanying drawings. [Brief description of the drawings] Fig. 1 is a view showing a hardware structure of an on-board warning system 5 according to an embodiment of the invention.

Fig. 7 is a flowchart showing a procedure for illuminating a warning lamp in step S4 in the modified example. Mode for carrying out the invention

[0020] An on-board warning system according to an embodiment of the invention will be described below with reference to the drawings. The on-board warning system of this embodiment is mounted in a vehicle to monitor monitoring targets mounted in each seat in a passenger compartment for monitoring targets. When it is determined that the condition of the monitoring target in one of the seats has reached a warning level, the on-board warning system directly issues a warning to an occupant seated in the seat in question.

[0021] Fig. 1 is a view showing a hardware structure of an on-board warning system 5 of this embodiment. The on-board warning system 5 is essentially composed of a connector 10 installed with a control function, which is connected to an ECU (Electronic Control Unit) 30 that integrally controls devices mounted in a vehicle in communication with the unit.

[0022] A speed sensor 31 and an engine speed sensor 32, as well as an on-board camera 33, a speaker 34, and a control switch (SW) 35 are connected to the ECU 30. The speed sensor 31 detects a speed of the vehicle. The engine speed sensor 32 detects an engine speed. The on-board camera 33 is mounted in a ceiling to capture an image of the interior of a passenger compartment from above. The speakers 34 output a warning sound. The control switch 35 transmits commands input by a driver or the like to the ECU 30.

[0023] The connecting device 10 installed with a control function has a plurality of connecting units 61, 63 connected to various devices, and includes a microcomputer (not shown) configured to control the devices connected to the connecting units 61, 63. A plurality of devices provided in each of the seats 12, 13, 14, 15, and 16 are similarly connected to the connecting device 10 installed with a control function. The seat 12 is a driver's seat. The seat 13 is a passenger's seat. The seat 14 is a rear seat behind the driver's seat. The seat 15 is a rear seat behind the passenger's seat. The seat 16 is a center rear seat.

[0024] As one of the plurality of devices, a warning light 21 is connected to the control-function-installed connector 10 via an LED connection unit 61. Furthermore, a seat belt buckle switch 22, a door open detection SW 23, a window open and closed detection SW 24, and a seat sensor 25 are connected to the control-function-installed connector 10 via respective SW connection units 63.

[0025] Warning lights 21 for the rear seats are LED light sources that are mounted in a ceiling 7A (see Fig. 5) are provided to face the front areas of the corresponding rear seats and are oriented so as to be within the field of vision of passengers seated in the rear seats. Warning lamps 21 for the driver's seat and the front passenger seat are provided on an instrument panel. These warning lamps 21 illuminate a seat belt fastening symbol, such as that shown in Fig. 5, for example when they issue a warning for an unfastened seat belt.

[0026] The buckle switch 22 is installed in a buckle of a seat belt device. The buckle switch 22 is turned on when a tongue plate of the seat belt is locked in the buckle, and is turned off when the tongue plate is pulled out of the buckle, thus detecting that the seat belt is unbuckled (hereinafter referred to as an unbuckled seat belt).

[0027] The door open detection SW 23 detects whether a door is not fully closed. The door open detection SW 23 is turned on when the door is not fully closed and is turned off when the door is fully closed. The window open and closed detection SW 24 detects whether a window is open or closed. The window open and closed detection SW 24 is turned on when the window has been left open (hereinafter referred to as an open window) and is turned off when the window is fully closed. In the case where a three-person bench is used as the rear seat, a door open detection SW and a window open and closed detection SW are not provided for a middle seat. Furthermore, the seat belt buckle switch 22, the door open detection switch SW 23, and the window open and closed detection SW 24 are assigned to multiple state detection modules.

[0028] The connecting device 10 installed with a control function is configured to determine whether or not the state of at least one of the detection targets has reached a warning level at which a warning is to be issued, based on signals supplied to it from these switches. That is, the connecting device 10 installed with a control function corresponds to a warning determination module.

[0029] The seat sensor 25 (an occupant detection module) is embedded in each of the seats 12 to 16. The seat sensor 25 detects a weight exerted by the occupant on the seat and outputs a signal indicating whether or not the detected weight exceeds a threshold to the link unit 10 installed with a control function. The threshold is a value to be used when determining whether or not the occupant is seated in the seat. That is, the link unit 10 installed with a control function determines that the occupant is seated in the seat when the detected weight exceeds the threshold.

[0030] The display 42 and the built-in meter 41 are connected to the control-function-installed connection unit 10 via the ECU 30. The display 42 is mounted above an interior rearview mirror (see Fig. 5) and displays warning symbols for unfastened seat belts in such a way that they correspond to the seating positions (see Fig. 5). For example, if the occupant sitting in the seat 13 has not fastened his or her seat belt, as in Fig. 5, the warning image is displayed in an upper left side position on the display 42, and if the occupant sitting in the seat 14 does not fasten his or her seat belt, the warning image is displayed in a lower right side position on the display 42. The instrument cluster 41 is arranged below the instrument panel and displays images representing open and closed doors of the vehicle as one of various pieces of information (see Fig. 5).

[0031] An illumination lamp 45 is connected to the connection device 10 installed with a control function via the LED connection units 61. The illumination lamp 45 functions as a decorative light.

[0032] Fig. 2 is a view showing connections of wire harnesses 51, 53, 54 connected to the connector 10 installed with a control function. The LED connector units 61, on which the warning lamps 21 and the illumination lamp 45, which are illumination devices, are mounted, are connected to the connector 10 installed with a control function via the wire harnesses 51. The SW connector units 63, on which the seat belt buckle SW 22, the door open detection SW 23, the window open and closed detection SW 24, and the seat sensor 25, which are SW and sensor devices, are mounted, are connected to the connector 10 installed with a control function via the wire harnesses 53. Further, the display 42 and the panel meter 41 are directly connected to the connector 10 installed with a control function via the wire harnesses 54.

[0033] Fig. 3 is a view showing the arrangement of the wire harnesses 51 for the LED connection units 61. The wire harnesses 51 for the LED connection units 61, on which the warning lamps 21 are mounted, are laid so as to extend at a small distance in front of the rear seats of the vehicle 8 on a rear side of the ceiling 7A (see Fig. 5).

[0034] The operation of the on-board warning system 5, which is constructed in the manner described above, will now be described. Fig. 4 is a flowchart showing a procedure for executing warning operations. First, the link device 10 installed with a control function obtains the states of the monitored targets for each seat (S1). To this end, the states of the seat belt, door, and window, which are the devices to be monitored, are obtained from the buckle switch 22, the door open detection SW 23, and the window open and closed detection SW 24, respectively. The number and type of monitoring targets can be arbitrarily set. For example, only the seat belt and door are monitored if necessary, excluding the window.

[0035] The connecting device 10 installed with a control function detects the state of the seat sensor 25 embedded in each of the seats to detect whether the occupant is seated in the seat (S2). Next, the connecting device 10 installed with a control function detects whether the state of the monitoring target has reached a warning level at which a warning is to be issued, and whether the occupant is seated in the seat located close to the monitoring target (S3).

[0036] When the link device 10 installed with a control function determines that the state of the monitoring target has reached the warning level and that the occupant is sitting in the seat near the monitoring target, the link device 10 installed with a control function turns on the warning lamp 21 corresponding to the seat in question (S4). That is, the link device 10 installed with a control function corresponds to a control module. By viewing the warning lamp 21 thus turned on, the occupant sitting in the seat in question is given an opportunity to know that the warning has been issued for the seat in which the occupant is sitting. Thereafter, the occupant performs a warning canceling operation to cancel the issued warning. For example, if the unfastened seat belt warning is used, the occupant fastens his or her seat belt.If the warning is triggered for a door that is not completely closed, the occupant opens and closes the door again. If the warning is triggered for an open window, the occupant closes the window completely. Once the occupant has completed these actions, the warning condition is canceled.

[0037] In the process at step S4, if the warning lamp for the seat other than the driver's seat is turned on, the link device 10 installed with the control function also turns on the warning lamp 21 for the driver's seat together with the warning lamp for the seat in question. This makes it possible for the driver to be aware that the warning has been issued, thereby enabling the driver to determine whether he or she can start the vehicle. When this happens, the link device 10 installed with the control function further displays a warning image corresponding to the issued warning on the display 42 or the instrument cluster. Thereafter, the link device 10 installed with the control function returns to step S1 to perform the same process.

[0038] On the other hand, if the control-function-installed connector 10 determines that the condition triggering the warning is resolved, or that no occupant is sitting in the seat in question, the control-function-installed connector 10 turns off the warning lamp (S5). Thereafter, the control-function-installed connector 10 returns to step S1 to perform the same operation. The control-function-installed connector 10 may terminate the warning operations after the operation in step S5 is completed.

[0039] According to the structure of this embodiment, it is first detected whether the occupant is sitting in the seat, and when it is detected that the occupant is sitting in the seat, the warning is issued. However, the warning may be issued without detecting whether the occupant has sat in the seat. If this happens, the process in step S2 is omitted, and in step S3, the connecting device 10 installed with a control function determines whether the state of the monitoring target has reached the warning level. This can simplify the structure of the on-board warning system, whereby the on-board warning system can be installed in the vehicle at a relatively low cost.Furthermore, in this case, since the connection unit 10 installed with a control function determines that the state of the monitoring target has reached the warning level even though no occupant is sitting in the seat, the connection device 10 installed with a control function is configured to stop issuing the warning for the seat in question when a predetermined period of time, for example, 60 seconds, has elapsed since the vehicle is started.

[0040] The connection device 10 installed with a control function can be configured to turn off the warning light when a predetermined condition occurs after the warning light illuminates, regardless of whether the connection unit 10 installed with a control function detects a passenger in the seat. As an example of the predetermined condition, it is possible to use the aforementioned length of the predetermined period of time. Furthermore, according to another example, it is possible to use the detection of a predetermined signal depending on an operation performed by the driver to start the vehicle.As an example of the predetermined signal depending on the starting operation, it is possible to cause a signal indicating that a service brake or a parking brake is released, a signal indicating that the select range of an automatic transmission (AT) mounted in the vehicle is shifted to the D range, a signal indicating that a position of an accelerator pedal becomes larger than 0, a signal indicating that a throttle position becomes larger than at the time of idling, and a signal indicating that a vehicle speed becomes larger than 0.

[0041] Fig. 5 is a view illustrating how a warning is displayed in the warning lamps 21 provided in the ceiling 7A of the passenger compartment 7, the display 42 arranged on the windshield 8A side, and the instrument cluster 41. The three-person bench seat is used as the rear seat, and thus, three rear seat warning lamps 21 are provided in the ceiling 7A so as to be aligned in a width direction of the vehicle 8, respectively. In addition to the warning lamps 21, the seat belt unfastened warning image and the door open warning image are displayed, respectively, on the display 42 and the instrument cluster 41. The driver can thus immediately know that the warning is being issued by looking at the display 42 and the instrument cluster 41.

[0042] In this way, in the on-vehicle warning system 2, when one of the plurality of monitoring targets being monitored with respect to the monitoring target reaching the warning level, the warning lamp 21 provided in the ceiling 7A or the warning lamp 21 provided in the instrument panel facing the seat located near the target device is turned on when the warning level occurs. The occupant in the seat in question becomes aware that the warning is being issued to the seat in which the occupant is sitting because the warning lamp 21 located near him or her is turned on. Then, the occupant performs a warning cancellation operation to cancel the warning. For example, if the occupant has not yet fastened the seat belt, the occupant fastens the seat belt.If the door near the occupant is not fully closed, the occupant opens the door again and then closes the door completely. If the window near the occupant is open, the occupant closes the window completely. When the condition triggering the warning is resolved, warning light 21 will automatically turn off.

[0043] Therefore, according to the on-board warning system, when the status of at least one of the multiple monitoring targets reaches the warning level, the warning can be issued directly to the occupant sitting in the seat near the monitoring target at the warning level. This allows the occupants sitting in the seats to be aware of the warning being issued, forcing the occupants to immediately perform the warning cancellation process.

[0044] Furthermore, the seat sensors installed in the seats detect whether the occupants are seated or not, and thus, the warning can be issued precisely by linking the occupant detection and the warning. Consequently, no unnecessary warning is issued, thus saving electrical energy.

[0045] Furthermore, the same warning as the warning issued for the seat other than the driver's seat is issued by the driver's seat warning light, allowing the driver to be aware of all issued warnings and efficiently determine whether or not to operate the vehicle. The warning lights are also provided in the ceiling, and therefore, general ceiling-mounted lights can be used as warning lights, increasing application flexibility.

[0046] If the monitoring target is an unfastened seat belt, the seat belt can be forced to close. Furthermore, if the monitoring target is a door that is not completely closed, the door can be requested to close completely. If the monitoring target is an open window, the window can be requested to close completely. Modified example

[0047] In the above-described embodiment, the seat belt buckle sign displayed when the unbuckled seat belt is detected is described. However, in a modified example, a configuration is described in which the warning level of the monitoring target can be recognized by the color of the warning light. In the embodiment, the LED light sources are monochrome. However, in the modified example, the LED light sources are each composed of three LED devices that emit red (R), green (G), and blue (B) as light beams to emit a light beam of any color.

[0048] Fig. 6 is a view showing the registered contents of an illumination table 60 in which colors of warning lamps when illuminated are registered according to the modified example. In this illumination table 60, when a monitoring target is an unfastened seat belt (denoted by NG in the figure), the color of the warning lamp is orange when illuminated. When a monitoring target is a door that is not completely closed, the color of the warning lamp is red when illuminated. Further, when the monitoring target is an open window, the color of the warning lamp is yellow when illuminated.

[0049] In the event that two or more monitoring targets are detected, for example when two monitoring targets are monitored as an unfastened seat belt and a door that is not fully closed, and this is detected, the color of the warning light, when it illuminates, changes periodically between orange and red. Furthermore, in the case that two monitoring targets are monitored as being detected, as an unfastened seat belt and an open window, the color of the warning light, when it illuminates, changes periodically between orange and yellow. Furthermore, when two monitoring targets are monitored as being detected as being not fully closed door and an open window, the color of the warning light, when it illuminates, changes periodically between red and yellow.

[0050] Furthermore, when three monitoring targets as unfastened seat belt, not fully closed door and open window are monitored as being detected, the color of the warning light, when illuminated, changes periodically between orange, red and yellow in a sequential manner.

[0051] In the case of two or more monitoring targets being monitored as detection targets, the color of the warning light is configured to change periodically. However, the warning light can be turned on in a different color (for example, pink) instead of turning on to change colors periodically.

[0052] Fig.7 is a flowchart illustrating a procedure for turning on a warning lamp in step S4 in the modified example. Operations in the other steps of the modified example are similar to the operations in steps S1 to S3, S5 of the previously described embodiment. That is, when the state of the monitoring target has reached the warning stage and the occupant is sitting in the seat near the monitoring target during the warning stage, the link device 10 installed with a control function determines which monitoring target results in the warning (S41). At this time, an unfastened seat belt, a partially closed door, and an open window are arbitrarily determined as the monitoring target.

[0053] Based on the monitoring target thus determined, the link device 10 installed with the control function retrieves the illumination table 60 to turn on the warning light according to the determined monitoring target (S42). For example, if the monitoring target is a door that is not completely closed, the warning light 21 is turned on in red. The link device 10 installed with the control function then returns to the initial step to perform the initial operation.

[0054] This allows occupants to identify the monitoring targets from the colors of the warning lights. Therefore, occupants can initiate a warning deferral operation to cancel the warning as soon as they recognize which monitoring target triggered the warning. Furthermore, if two or more monitoring targets trigger a warning, occupants can identify the warning monitoring targets individually.

[0055] The technical scope of the invention is not limited to the embodiment. The above-described embodiment can be modified and / or improved in various ways without departing from the technical scope of the invention. For example, although the seat sensors are used in the embodiment to detect whether or not the occupants are seated in the seats, an on-board camera provided in the ceiling or the like may be used instead of the sensors to capture an image of the interior of the passenger compartment to thereby detect the occupants sitting in the seats by analyzing the thus captured image.

[0056] Further, although in the embodiment the warning is given by illuminating the warning lamps, a warning sound may be output from a speaker together with the illumination of the warning lamps.

[0057] Although the warning lights are provided in the ceiling in the embodiment, the invention is not limited thereto. Therefore, the warning lights may be provided in any location other than the ceiling that is within the occupants' field of vision. For example, in the case of rear seats, the warning lights may be mounted on the headrests of the front seats. Furthermore, in the case of front seats, the warning lights may be provided on the instrument panel. Furthermore, the warning lights may be provided on the interior side areas of the passenger compartment.

[0058] Although an unfastened seat belt, a partially closed door, and an open window are specified as the monitoring targets in the embodiment, the invention is not limited to these. Smoking can also be used as a monitoring target, which is detected by a smoke sensor.

[0059] Furthermore, the characteristics of the embodiment of the on-board warning system according to the invention are given in a brief and summarized manner below under [1] to [7]. [1] The on-board warning system (5) mounted in the vehicle, the on-board warning system being provided with: the status detection modules (the belt buckle switch 22, the door open detection switch 23, the window open and closed detection SW 24), which are provided for respective seats and which detect the status of at least one of the monitoring targets, the warning determination module (the connecting device 10 installed with control function) for determining whether the conditions of the monitoring targets have triggered the warnings or not, the warning lights (21) provided individually for the seats, and the control module (the connecting device 10 installed with a control function) for switching on the warning lights (21) when the warning determination module determines that the conditions of the monitoring targets have triggered the warnings, wherein the control module (the connecting device 10 installed with a control function) turns on the warning lamp (21) provided for an occupant sitting in the seat corresponding to the state detection module (the seat belt buckle switch 22, the door open detection SW 23, the window open and closed detection SW 24) that detects that the state of the monitoring target has reached the warning level, and the control module switches off the warning light when the warning level condition is canceled. [2] The on-board warning system (5) from [1], which is equipped with: the occupant detection modules (the seat sensors 25) for detecting that the occupants are sitting in the seats, wherein the control module (the connecting device 10 installed with a control function) turns on the warning lights (21) when it is detected that the occupants are sitting in the seats and it is determined that the conditions of the monitoring targets in the seats have reached the warning level.
