Description

  The present invention relates to a vehicle door control device that controls opening of a vehicle door, and more particularly, to a vehicle door control device that supports escape of a passenger or the like out of the vehicle when the vehicle is submerged.

Conventionally, when a vehicle such as an automobile falls into water due to an unexpected accident or the like, a door lock releasing device disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-269028 is provided in order to support the escape of a driver or the like outside the vehicle. is there. This door lock releasing device is provided with a submergence sensor for detecting submergence of a vehicle, and releases the door lock by an actuator when submergence is detected.
JP 2003-269028 A

  In the conventional door lock releasing device, the door lock is automatically released so that the occupant can open the door by opening the door, but the occupant eventually opens the door. That is what must be done. On the other hand, an automatic door opening and closing device that automatically opens and closes a door is also known. Therefore, by using an automatic door opening / closing device together with the conventional door lock releasing device, the vehicle door that has fallen into water can be automatically opened.

  However, even when the conventional door lock releasing device and the automatic door opening / closing device are used, the pressure on the outside is often very large in water with respect to the inside of the vehicle. In this state, even if an automatic door opening and closing device is used, a great amount of force is required to open the door, and there is a problem that the door cannot be reliably opened.

  Then, the subject of this invention is providing the vehicle door control apparatus which can open the door of a vehicle reliably, when a vehicle is submerged.

  In order to solve the above-described problem, a vehicle door control device according to the present invention is a vehicle door control device provided in a vehicle including a door, and the submergence detection unit that detects submergence of the vehicle, When it is determined that the vehicle is in a fully submerged state by the submerged state determining means for determining whether the vehicle is in a completely submerged state where the vehicle is submerged to the room And door driving means for operating the door in the opening direction.

  In the vehicle door control device, it is determined whether or not the vehicle is completely submerged until the vehicle is submerged after the submergence detecting means is detected. If it is determined that the vehicle is completely submerged, the door is opened. Is done. In the incomplete submerged state where a large amount of air remains inside the vehicle, the outside is in a state where the pressure is very large relative to the inside of the vehicle. If an attempt is made to open the door by the door driving means in this state, a large amount of electric power is required, and further, the door driving force may be inferior to the water pressure, and the door cannot be opened.

  In this regard, in the vehicle door control device according to the present invention, the door is opened after the vehicle is completely submerged. When the vehicle is completely submerged, a large amount of water has entered the inside of the vehicle, and the pressure difference between the inside and the outside of the vehicle is very small. For this reason, since the door can be opened with a relatively small force, the door of the vehicle can be reliably opened.

  Here, the completely submerged state in the present invention refers to a state in which the interior of the vehicle is filled with water, or a state in which air still remains in part but water has entered most of the passenger compartment.

  Preferably, the submergence state determination unit determines that the vehicle is in a completely submerged state when a predetermined time has elapsed after the submergence detection unit detects submergence of the vehicle.

  When time elapses from the start of submergence, water enters the vehicle interior, and eventually the vehicle is completely submerged. Further, the present inventors have found that the time until a vehicle that has fallen into water reaches a completely submerged state is determined to some extent depending on the type of vehicle. For this reason, a complete submerged state can be determined only by measuring a predetermined time after the vehicle starts submerging. Therefore, in order to detect complete submersion, for example, it is not necessary to provide sensors at a plurality of locations in the vehicle, so that the apparatus as a whole can be simplified.

  Further, window opening amount detection means for detecting the opening amount of the window provided in the door is provided, and a predetermined time is set based on the window opening amount detected by the window opening amount detection means. be able to.

  Thus, by setting the predetermined time for determining that the state is completely submerged based on the opening amount of the window, it is possible to set the time required for complete submergence more accurately.

  Further, the predetermined time can be set shorter as the opening amount of the window detected by the window opening amount detection unit when the submergence detecting unit detects the submergence of the vehicle.

  When the amount of window opening when the vehicle is submerged is large, the amount of water inflow increases. Therefore, if the predetermined time until determining that the vehicle is completely submerged is set short, the complete submergence state can be determined more accurately.

  Further, the vehicle door control device is further provided with a window driving unit that is provided with a window that can be opened and closed on the door, and that operates in a direction to open the window when the submergence detection unit detects submergence of the vehicle. Can do.

  If it carries out like this, since it will operate | move so that a window may be opened with the detection of submergence, the water pressure concerning a window part will be reduced when opening a door after reaching a complete submergence state, and opening of each door will become easy.

  Moreover, it can be set as the aspect by which the submergence detection means is provided in the vehicle interior.

  If the submergence detecting means is provided outside the vehicle, it may be erroneously detected as submerged in response to, for example, rain water or water in a puddle. In this respect, in the vehicle door control device according to the present embodiment, the submergence detection means is provided in the vehicle interior. For this reason, if water does not enter the vehicle, it is not determined that the vehicle has been submerged, so that it is possible to prevent misidentification of submergence during rainy weather and to detect the submerged state with higher accuracy.

  Further, the submergence detection means is provided at least in the front part of the interior of the vehicle, the indoor ceiling part, and the indoor floor part. When both the submergence detecting unit on the ceiling and the submergence detecting unit on the indoor floor detect submersion, the vehicle can be determined to be in a completely submerged state.

  Generally, since the center of gravity of a vehicle is located on the front side where the engine is mounted, the vehicle is submerged first from the front side when submerged. Further, the posture of the vehicle when submerged is not necessarily on the floor side (side on which the tire is located), and may be on the ceiling side. For this reason, if the submergence detection means at the front part of the room detects submersion and the submersion is detected when both the indoor ceiling part, the indoor floor part and the submergence detection means detect complete submersion, the submersion posture of the vehicle is different. Even if it is completely submerged, it can be determined correctly.

  The vehicle door control device according to the present invention can reliably open the door when the vehicle is submerged.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is used for the same element and the overlapping description may be abbreviate | omitted.

  FIG. 1 is a block diagram illustrating a configuration of a vehicle door control device 1 according to the first embodiment.

  As shown in FIG. 1, the vehicle door control device 1 includes a door ECU (Electronic Control Unit) 11, a door control ECU 12, and a body ECU 13. Each ECU 11, 12, 13 is configured mainly by a computer including a CPU, a ROM, and a RAM. The ROM stores various control routines including a braking control routine. These ECUs are connected to each other by a bus line 10 so that bidirectional communication is possible.

  The door ECU 11 is connected with a submergence sensor 14 which is a submergence detection means. The submergence sensor 14 is attached to the lower part on the indoor side of the door (not shown) of the vehicle. The submergence sensor 14 outputs a submergence detection signal to the door ECU 11 when detecting that the vehicle is submerged. The door ECU 11 outputs a submergence detection signal output from the submergence sensor 14 to the door control ECU 12.

  The door control ECU 12 is connected to a timer 15 and an actuator 16 that is a door driving means. Further, the door control ECU 12 has a function as a submerged state determination means for determining whether or not the vehicle is in a completely submerged state by a built-in CPU. When the submersion detection signal is output from the door ECU 11 to the door control ECU 12, the door control ECU 12 outputs an unlock instruction signal for instructing the body ECU 13 to unlock the door, and starts timing with respect to the timer 15. Output a signal. Further, the door control ECU 12 determines that the vehicle is in a completely submerged state when the timer 15 finishes counting the predetermined time. When it is determined that the state is completely submerged in this way, a lighting instruction signal for instructing lighting of the illumination 17 to be described later is output to the body ECU 13.

  Further, the door control ECU 12 outputs a drive signal to the actuator 16 after outputting these signals. The actuator 16 is connected to a vehicle door (not shown). When a drive signal is output to the actuator 16, the actuator 16 operates to open the door.

  The body ECU 13 is connected to the illumination 17. When a lighting instruction signal is output from the door control ECU 12 to the body ECU 13, the body ECU 13 turns on the illumination 17. The body ECU 13 is provided with an unlock drive circuit (not shown), and when the unlock instruction signal is output from the door control ECU 12 to the body ECU 13, the body ECU 13 unlocks the door. To work. Here, the illumination 17 includes a vehicle headlight and an interior lamp.

  Operation | movement of the vehicle door control apparatus 1 which concerns on this embodiment which has the above structure is demonstrated. FIG. 2 is a flowchart showing an operation procedure of the vehicle door control device according to the present embodiment.

  As shown in FIG. 2, when the control is started, first, the submergence sensor 14 detects the submergence to determine whether or not the vehicle is submerged (S1). When the vehicle starts to be submerged and water enters the vehicle interior, the volume of water accumulated in the vehicle interior increases and eventually reaches the height position of the submersion sensor 14. The submergence sensor 14 detects submergence when the water accumulated in the passenger compartment reaches the height at which the submergence sensor 14 is provided, and outputs a submergence signal to the door control ECU 12.

  When the submersion detection signal is output, the door control ECU 12 outputs to the body ECU 13 an unlock instruction signal for instructing unlocking of the door. When the unlock instruction signal is output from the door control ECU 12 to the body ECU 13, the body ECU 13 drives the unlock drive circuit to unlock the door (S2). By this unlocking operation, the door is unlocked when the door is locked, and the unlocked state is maintained as it is when the door is unlocked.

  When the process of unlocking the door is completed, the door control ECU 12 starts the timer 15 and starts time measurement by the timer 15 (S3). In the timer 15, it is determined whether or not a predetermined time period DT1 has elapsed (S4). In step S4, if it is determined that the time count T is less than DT1, the process is repeated until the predetermined time DT1 elapses. If it is determined that the time measured by DT1 has elapsed, the door control ECU 12 determines that the vehicle is in a completely submerged state.

  The time from when the vehicle falls into the water until it becomes completely submerged is determined to some extent depending on the type of vehicle due to the difference in the volume of the passenger compartment. Accordingly, the predetermined time DT1 is appropriately set depending on the vehicle type. By setting the predetermined time DT1 in this way, it is possible to accurately determine the complete submerged state.

  When the predetermined time DT1 has elapsed from the submerged state, the door control ECU 12 outputs a lighting instruction signal that instructs the body ECU 13 to turn on the illumination 17. When a lighting signal is output from the door control ECU 12 to the body ECU 13, the body ECU 13 turns on the illumination 17 (S5).

  After the illumination 17 is turned on, the door control ECU 12 controls the actuator 16 to operate in the direction to open the door (S6). When the door is opened, the vehicle is completely submerged, and a large amount of water is accumulated in the passenger compartment, and the pressure difference between the inside and the outside of the vehicle is reduced or eliminated. Therefore, when the door is opened by the actuator 16, a large force is not required and the door can be easily opened. It should be noted that by operating in the direction to open the door, in addition to a mode of completely opening the door, a mode of assisting the opening of the door can be adopted. Thus, the process ends.

  As described above, the vehicle door control device according to the present embodiment determines whether or not the vehicle is fully submerged until the vehicle is submerged after the submergence sensor detects the vehicle submergence. When judged, the door is opened. For this reason, since the door is opened after reaching a completely submerged state where the pressure difference between the water pressure and the pressure in the passenger compartment becomes small, the door can be reliably opened with a small force.

  In addition, since the submergence sensor is installed in the passenger compartment, it is possible to prevent misidentification of submergence due to water splashing during rainy weather or when running in a muddy environment. Furthermore, in this embodiment, since the determination of the complete submergence state is made based on whether or not a predetermined time has elapsed since the detection of the submergence of the vehicle, it is not necessary to provide a plurality of submergence sensors, and the apparatus can be simplified. In addition, the operation of opening the door is not started until a predetermined time until the submergence has passed. For this reason, for example, when the door is opened using the power of the battery, the power of the battery can be prevented from being wasted.

  Further, since the door lock is automatically released when the submergence sensor detects the submergence of the vehicle, it is possible to easily escape from the vehicle. Furthermore. Since the lights are turned on before the door is opened, it is possible to secure visibility in the water not only at night but also in the daytime and support escape.

  Next, a second embodiment of the present invention will be described. FIG. 3 is a block diagram showing the configuration of the vehicle door control device 2 according to the second embodiment of the present invention. In addition, about the structure similar to 1st Embodiment, description is abbreviate | omitted suitably.

  The vehicle door control device 2 includes a door ECU 21, a door control ECU 22, a window control ECU 23 that is a window opening amount detection unit, a body ECU 24, and an alarm ECU 25. These ECUs 21 to 24 are connected to each other by a bus line 20 so that bidirectional communication is possible.

  A submersion sensor 26 is connected to the door ECU 21. The submergence sensor 26 detects the submergence of the vehicle in the same manner as the submergence sensor 14 in the first embodiment, and outputs a submergence detection signal to the door ECU 21 when it detects that the vehicle is submerged. The door ECU 21 outputs the submergence detection signal output from the submergence sensor 26 to the door control ECU 22 and the alarm ECU 25, respectively.

  The door control ECU 22 is connected to a timer 27 and an actuator 28 that is a door driving means. When the submersion detection signal is output from the door ECU 21 to the door control ECU 22, the door control ECU 22 outputs a signal instructing the window control ECU 23 to detect the opening amount of the window. The window control ECU 23 detects the opening amount of the window based on the instruction signal from the door control ECU 22 and outputs the detected window opening amount signal to the door control ECU 22. The door control ECU 22 sets a predetermined time based on the output window opening amount signal and outputs a time measurement start signal to the timer 27.

  Further, the door control ECU 22 determines that the vehicle is completely submerged when the timer 27 finishes counting the predetermined time, and outputs a drive signal to the actuator 28. The actuator 28 to which the drive signal is output is connected to the door of the vehicle and operates to open the door.

  Further, the window control ECU 23 is connected to a window position detection sensor 29 and an actuator 30 as window driving means. The window position detection sensor 29 is attached inside the door, for example, and detects the window opening amount by detecting the position of the lower end of the window. The window position detection sensor 29 outputs the detected window opening amount to the door control ECU 22 via the window control ECU 23. The actuator 30 is connected to the window, and is operated in a direction to open the window when a drive signal is output from the window control ECU 23.

  The alarm ECU 25 is connected to notification means (not shown) such as a speaker. When a submergence detection signal is output from the door ECU 21 to the alarm ECU 25, the alarm ECU 25 outputs an alarm sound via a speaker or the like. Further, instead of the alarm sound, an announcement or the like for prompting escape may be output.

  Operation | movement of the vehicle door control apparatus which concerns on this embodiment which has the above structure is demonstrated. FIG. 4 is a flowchart showing an operation procedure of the vehicle door control device according to the present embodiment.

  As shown in FIG. 4, when the control is started, the submergence sensor 26 first detects submergence to determine whether the vehicle is submerged (S10). When the vehicle starts to be submerged and water enters the vehicle interior, the volume of water accumulated in the vehicle interior increases, and eventually reaches the height position of the submersion sensor 26. The submergence sensor 26 detects submergence when the water accumulated in the passenger compartment reaches the height at which the submergence sensor 26 is provided, and outputs a submergence signal to the door control ECU 22. The door control ECU 22 that has output the submergence detection signal outputs an instruction signal that instructs the window control ECU 23 to detect the opening amount of the window.

  The window control ECU 23 to which the instruction signal is output controls the window position detection sensor 29 to detect the window opening amount (S11), and based on the detection result of the window opening amount, whether or not the window is opened is determined. A determination is made (S12). This determination result is output from the window control ECU 23 to the door control ECU 22. Here, when it is determined that the window is not opened, the door control ECU 22 sets a predetermined time DT1 set in advance as the time-measurement time as in the first embodiment, and measures the time by the timer 27. Start (S15). Thereafter, the timer 27 determines whether or not a predetermined time DT1 that is a predetermined time T has elapsed (S16). In step S16, if it is determined that the measured time is less than DT1, the process is repeated until the predetermined time DT1 elapses. If it is determined that the time count DT1 has elapsed, the door control ECU 22 determines that the vehicle is in a completely submerged state, and controls the actuator 28 to operate in the direction to open the door (S17).

  On the other hand, when the opening of the window is detected in step S12, the predetermined time DT2 shorter than the predetermined time DT1 is set as the time measurement time, and the time measurement by the timer 27 is started (S13). Thereafter, the timer 27 determines whether or not a predetermined time DT1 that is a predetermined time T has elapsed (S14).

  The length of the predetermined time DT2 is set to a predetermined length shorter than the predetermined time DT1 in the present embodiment, but may be set according to the opening amount of the window. In this case, the ROM built in the door control ECU 22 stores in advance a reference table indicating the relationship between the window opening amount and the time required for complete submersion, and should be measured from the window opening amount indicated by the detection information. A predetermined time is determined.

  When the opening amount of the window is large, the amount of water flowing into the vehicle interior increases, and the time until the vehicle is completely submerged is shortened. Therefore, DT2 is set shorter than DT1. Further, the larger the window opening amount, the shorter the DT2. In this reference table, as shown in FIG. 5 (a), the set value of the predetermined time DT2 may be linearly changed with respect to the opening amount of the window, as shown in FIG. 5 (b). , It may be changed step by step.

  When the predetermined time DT2 has elapsed, the door control ECU 22 determines that the vehicle is in a completely submerged state, and controls the actuator 28 to operate to open the door (S17). Thus, the process ends.

  As described above, in the vehicle door control device according to the present embodiment, in addition to the effects shown in the first embodiment, when the opening of the window is detected at the time of submergence detection, until it is determined that the vehicle is completely submerged. The predetermined time is set shorter than when the window opening is not detected.

  Therefore, the larger the window opening amount when the vehicle is submerged, the faster the inflow of water into the passenger compartment and the shorter the time to reach the complete submerged state, so that the complete submerged state can be determined more accurately. .

  Subsequently, a third embodiment of the present invention will be described. The vehicle door control device according to the third embodiment is configured similarly to the second embodiment.

  Next, the operation of this embodiment will be described. FIG. 6 is a flowchart showing an operation procedure of the vehicle door control device according to the present embodiment.

  As shown in FIG. 6, when the control is started, the submergence sensor 26 first detects submergence to determine whether or not the vehicle is submerged (S20). When the vehicle starts to be submerged and water enters the vehicle interior, the volume of water accumulated in the vehicle interior increases, and eventually reaches the height position of the submersion sensor 26. The submergence sensor 26 detects the submergence when the water accumulated in the passenger compartment reaches the height at which the submergence sensor 26 is provided, and outputs a submergence signal to the door control ECU 22 and the alarm ECU 25.

  The alarm ECU 25 that has output the submergence detection signal activates the alarm and outputs an alarm sound from the speaker, thereby notifying the passenger that the vehicle is submerged (S21). Further, the door control ECU 22 that has output the submergence detection signal outputs an instruction signal for driving the actuator 30 to open the window to the window control ECU 23. The window control ECU 23 to which the instruction signal is output drives the actuator 30 to operate in a direction to open the window (S22).

  When the opening operation of the window is started, the door control ECU 22 activates the timer 27 to start measuring time (S23). Thereafter, the timer 27 determines whether or not a predetermined time DT3 set in advance has elapsed (S24). The predetermined time DT3 may be set equal to the predetermined time DT1 determined in advance by the vehicle type, or may be set to a time shorter than DT1 in consideration of the inflow of water due to the opening operation of the window. .

  If it is determined in step S24 that the predetermined time is less than DT3, the process in step S24 is repeated until the same time has elapsed. Eventually, when it is determined that the time count T has elapsed by DT3, the door control ECU 22 determines that the vehicle is completely submerged, and controls the actuator 28 to operate in the direction to open the door (S25). In this way, the process ends.

  In the vehicle door control device according to the present embodiment, when the vehicle is submerged, the window is opened. Therefore, the water pressure applied to the window portion of the door is reduced in the completely submerged state, so that the door can be opened more reliably. Further, since the danger is notified to the occupant by the alarm sound together with the detection of the submergence, the occupant can be informed of the necessity to escape.

  Next, a fourth embodiment of the present invention will be described. The vehicle door control device according to the fourth embodiment has the same configuration as that of the first embodiment, except that a plurality of submergence sensors are provided in the vehicle interior. About another point, it has the structure similar to the said 1st Embodiment.

  In the vehicle door control device according to the present embodiment, as shown in FIG. 7, a plurality of submergence sensors 40 to 43 are connected to the door ECU 11. Of these, the front submersion sensor 40 is provided in the vicinity of the center in the height direction of the front side surface of the vehicle interior, and the floor submersion sensor 41 is provided in the vicinity of the center in the front-rear direction of the floor portion of the vehicle interior.

  The roof submergence sensor 42 is provided near the center in the front-rear direction of the ceiling of the vehicle interior, and the rear submergence sensor 43 is provided near the center in the height direction of the rear side surface of the vehicle interior. These submergence sensors 40 to 43 are all submerged in the same manner as the submergence sensor 14 used in the first embodiment. To detect.

  Next, the operation of the vehicle door control device according to the present embodiment will be described. FIG. 8 is a flowchart showing an operation procedure of the vehicle door control device according to the present embodiment.

  As shown in FIG. 8, when the control is started, it is first determined whether or not the front submersion sensor 40 shown in FIG. 7 has detected submersion in the passenger compartment (S30). If the front submergence sensor 40 detects submergence, it is next determined whether the floor submergence sensor 41 has detected submergence (S31). As a result, when the floor submergence sensor 41 does not detect submergence, the process of step S31 is repeated until the floor submergence sensor 41 detects it.

  If submersion is detected by the floor submersion sensor 41 in step S31, it is then determined whether the roof submersion sensor 42 has detected submersion (S32). As a result, when the roof submergence sensor 42 has not detected submergence, the process returns to step S31 and the floor submergence sensor 41 detects submergence. On the other hand, when submersion by the roof submersion sensor 42 is detected, the door control ECU 12 determines that there has been complete submersion. Then, the actuator 16 is controlled to operate in a direction to open the door.

  As described above, in the vehicle door control device according to the present embodiment, after the front submergence sensor 41 detects submergence, when both the floor submergence sensor 41 and the roof submergence sensor 42 detect submergence, the vehicle is completely Determined to be submerged. Generally, since the center of gravity of a vehicle is located on the front side where the engine is mounted, the vehicle is submerged while being inclined forward from the front side when submerged. Therefore, when water enters the vehicle, the front submergence sensor 40 first detects submergence.

  Also, the vehicle posture when submerged is when the floor side (side where the tire is located) is down as shown in FIG. 7A and when the ceiling side is down as shown in FIG. 7B. The order in which the floor submersion sensor 41 and the roof submersion sensor 42 detect submersion differs depending on the posture. However, when all the three submersion sensors detect submergence, it is determined that the submergence state is complete, so that the complete submergence determination can be correctly performed even if the submersion posture of the vehicle is different.

  Some vehicles have a center of gravity located on the rear side, and may be submerged first from the rear side when submerged. In this case, after the rear submergence sensor 43 detects submergence, when both the floor submergence sensor 41 and the roof submergence sensor 42 detect submergence, it is the same if it is determined that the vehicle is in a completely submerged state. The effect of can be obtained.
