[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-286213 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, there have been many cases of vehicles being submerged in water due to torrential rains, typhoons, and the like. Electrical components installed in vehicles, such as the engine room and battery, can suffer serious malfunctions due to flooding. Even if the water recedes after flooding, the electrical components may have malfunctioned at the time of flooding, or the moisture remaining inside may cause malfunctions at a later date. In such cases, it is difficult to check from the outside whether the electrical components have been submerged in water. For this reason, if someone handles the electrical components carelessly without knowing that they have been submerged in water, it may result in serious malfunction of the vehicle.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a water flooding detection system, a water flooding detection method, and a water flooding detection program that can prevent careless handling when water has occurred or is at risk of flooding inside a vehicle. [Means for solving the problem]

[0006] In order to solve the above problems, the water flooding detection system of the present invention is, for example, a water flooding detection system that detects water flooding in equipment mounted on a vehicle, and includes a detection unit that detects water flooding, the detection unit having a first water flooding detection unit provided near the lower end of the equipment and a second water flooding detection unit provided near the upper end of the equipment, an output unit that performs processing regarding water flooding based on the detection result by the detection unit, a determination unit that makes a determination regarding water flooding of the equipment based on the detection result by the detection unit, and an output control unit that outputs an instruction to control the operation of the output unit to the output unit, wherein the determination unit determines that there is a sign of water flooding of the equipment when it is detected that water has reached the first water flooding detection unit, and determines that the equipment is flooded when it is detected that water has reached the second water flooding detection unit, and the output control unit outputs different instructions depending on whether the determination unit determines that there is a sign of water flooding of the equipment and whether the equipment is flooded.

[0007] A water flooding detection method according to another aspect of the present invention is, for example, a water flooding detection method for detecting water flooding in equipment mounted on a vehicle, and includes a determination step of making a determination regarding water flooding of the equipment based on the detection result from a detection unit having a first water flooding detection unit provided near the lower end of the equipment and a second water flooding detection unit provided near the upper end of the equipment, and an output step of outputting an instruction to control the operation of an output unit that performs processing regarding water flooding based on the detection result by the detection unit, wherein the output step is characterized in that different instructions are output when it is determined that there are signs of water flooding in the equipment and when it is determined that the equipment is flooded.

[0008] A water flooding detection program according to another aspect of the present invention is, for example, a water flooding detection program for detecting water flooding in equipment mounted on a vehicle, which causes a computer to function as: a detection unit that detects at least water flooding, the detection unit having a first water flooding detection unit provided near the lower end of the equipment and a second water flooding detection unit provided near the upper end of the equipment; a judgment unit that makes a judgment regarding water flooding in the equipment based on the detection result by the detection unit; and an output control unit that outputs instructions to the output unit to control the operation of the output unit, and the output control unit outputs different instructions depending on whether the judgment unit determines that there is a sign of water flooding in the equipment or not and whether it determines that the equipment is flooded. The computer program can be provided by downloading via a network such as the Internet, or can be provided by recording it on various computer-readable recording media such as a CD-ROM.

[0009] In any of the above aspects of the present invention, the detection unit is provided at the bottom end or below the device, and determines whether there is a sign of flooding of the device or whether the device has been flooded, and outputs different instructions to the output unit depending on the determination result. This allows the user of the vehicle to understand the flooding situation in detail. Therefore, careless handling can be prevented in advance when flooding has occurred or there is a risk of flooding inside the vehicle.

[0010] The output control unit may output a flood pre-warning that warns of the signs of flooding when the determination unit determines that there is a sign of flooding, and may output a flood occurrence warning that warns of flooding when the determination unit determines that flooding has occurred, and the output unit may output warnings in different modes depending on whether the output control unit has output the flood pre-warning or the flood occurrence warning, thereby enabling a user to more clearly grasp the situation of the vehicle.

[0011] The output unit may have an air suspension, and when the determination unit determines that there is a sign of flooding, the output control unit may output a control command to the air suspension to increase the vehicle height of the vehicle, thereby preventing flooding of equipment.

[0012] The determination unit does not need to determine that there is water flooding when the second water flooding detection unit detects that water has reached the first water flooding detection unit, thereby making it possible to prevent false detections and ensure detection accuracy.

[0013] The detection unit has a third water inundation detection unit provided near an end of a second device different from the first device among the devices, and a fourth water inundation detection unit provided near an upper end of the second device, and the determination unit does not need to determine that there is a sign of water inundation or that water has actually inundated if the water inundation detection unit that is provided at the bottom among the first water inundation detection unit, the second water inundation detection unit, the third water inundation detection unit, and the fourth water inundation detection unit does not detect that water has reached the water inundation detection unit. This can increase the accuracy of detection.

[0014] The control unit may have a storage unit that stores the detection result obtained from the detection unit or the determination result by the determination unit, and a reception unit that receives input from a user, and the output control unit may output the result stored in the storage unit to the output unit when the reception unit receives the input. This makes it possible to grasp the flooding situation in detail at a desired timing. Effect of the Invention

[0015] According to the present invention, it is possible to prevent careless handling in cases where water has entered the interior of a vehicle or there is a risk of water entering the interior of the vehicle. [Brief description of the drawings]

[0017] Hereinafter, an embodiment of a water-immersion detection system according to the present invention will be described in detail with reference to the drawings. The water-immersion detection system is a device that detects water ingress into components such as an engine room or a battery mounted on a vehicle and takes measures against the water ingress. The water-immersion detection system also detects signs of water ingress in a situation in which the components are gradually becoming submerged in water and takes measures.

[0018] <First embodiment> FIG. 1 is a schematic side view showing an example of a water flood detection system 1 according to a first embodiment mounted on a vehicle 100. The vehicle 100 may be, for example, a truck, a passenger car, or other traveling machinery. The vehicle 100 has an engine 110 and a battery 120. In FIG. 1, the engine 110 is provided below the driver's seat and above the front wheels, and the battery 120 is mounted near between the front and rear wheels. Note that the engine 110 and the battery 120 are examples of equipment that may be flooded, and the equipment is not limited to the engine 110 and the battery 120.

[0019] 1 is merely an example, and is not limited to this. For example, the battery 120 may be disposed at a higher position than the engine 110.

[0020] A water ingress detection unit 11 is provided at the lower end of the engine 110, and a water ingress detection unit 12 is provided at the upper end of the engine 110. A water ingress detection unit 13 is provided at the lower end of the battery 120, and a water ingress detection unit 14 is provided at the upper end of the battery 120.

[0021] 1, water flood detection units 11, 12 are provided at the lower and upper ends, respectively, of engine 110, and water flood detection units 13, 14 are provided at the lower and upper ends, respectively, of battery 120, but the arrangement of water flood detection units 11-14 is not limited to this. Water flood detection units 11-14 only need to be provided near the upper and lower ends of the equipment (engine 110 and battery 120), and may also be provided above and below the equipment, slightly separated from the equipment (for example, a few centimeters).

[0022] 2 is a schematic diagram showing an example of the water flood detection units 11-14 provided in the water flood detection system 1. The water flood detection units 11-14 are sensors that detect water flooding, i.e., whether the liquid level has reached a predetermined height. Since the water flood detection units 11-14 have the same configuration, the following description will be given taking the water flood detection unit 11 as an example.

[0023] The water submersion detection unit 11 mainly has a water detection sensor 111 and a cover 112. The water detection sensor 111 is a sensor that detects contact with water. The water detection sensor 111 has two electrodes, and detects contact with liquid such as water when the two electrodes come into contact with the liquid and a current flows through the liquid. However, the form of the water detection sensor 111 is not limited to this.

[0024] The cover 112 is, for example, a long and narrow box-like body, and the water detection sensor 111 is housed in its inner upper end. The cover 112 may have any shape that includes a tubular housing portion that is covered at least at its upper end. For example, the side surface of the cover 112 may be cylindrical or polygonal tubular. A water intake port 113 is formed in the lower end of the cover 112.

[0025] When the vehicle 100 is submerged, water enters the cover 112 through the water inlet 113, contacts the water detection sensor 111, and the submersion detection unit 11 detects the submersion. On the other hand, when water gets on the vehicle 100 during normal operation due to rain, splashes, or other factors other than submersion, the cover 112 blocks the water and prevents it from reaching the water detection sensor 111. This makes it possible to prevent erroneous detection of cases other than submersion as submersion.

[0026] When water enters cover 112 from water inlet 113, an air hole (not shown) is formed near the upper end of cover 112 to allow air inside cover 112 to escape to the outside of cover 112. Such a configuration of cover 112 is common technical knowledge and may be appropriately configured depending on the specific embodiment of cover 112.

[0027] The form of the water ingress detection units 11 to 14 is not limited to this. For example, a device that detects the ingress of water by water pressure may be used as the water ingress detection unit.

[0028] Fig. 3 is a functional block diagram showing an example of the functional configuration of the water inundation detection system 1. As shown in Fig. 3, for example, the water inundation detection system 1 mainly includes a detection unit 10, a control unit 20, and an output unit 30. The detection unit 10, the control unit 20, and the output unit 30 are configured to be able to communicate with each other via wired or wireless communication.

[0029] The detection unit 10 mainly has a plurality of water submersion detection units 11-14. The water submersion detection unit 11 provided at the lower end of the engine 110 detects that the water surface has reached the vicinity of the lower end of the engine 110. The water submersion detection unit 12 provided at the upper end of the engine 110 detects that the water surface has reached the vicinity of the upper end of the engine 110. Similarly, the water submersion detection unit 13 provided at the lower end of the battery 120 detects that the water surface has reached the vicinity of the lower end of the battery 120. The water submersion detection unit 14 provided at the upper end of the battery 120 detects that the water surface has reached the vicinity of the upper end of the battery 120. The detection result in the detection unit 10 is output to the control unit 20.

[0030] The control unit 20 can be realized by using an information processing device such as a dedicated or general-purpose server computer. Specifically, the control unit 20 includes an arithmetic unit such as a CPU (Central Processing Unit) for executing information processing, and a storage device such as a RAM (Random Access Memory) or a ROM (Read Only Memory). The arithmetic unit operates according to a program stored in the storage device. The program can be provided by downloading via a network, or by recording it on various computer-readable recording media.

[0031] The control unit 20 mainly has functional units such as a determination unit 21 and an output control unit 22 as software resources.

[0032] The determination unit 21 is a functional unit that acquires the detection result by the detection unit 10 and makes a determination as to whether the devices (engine 110, battery 120) are flooded based on the detection result. For example, the determination unit 21 acquires information on the positional relationship between the devices (engine 110, battery 120) and the flood detection units 11-14 and makes a determination as to whether the devices are flooded based on the information and the detection result by the detection unit 10.

[0033] In this embodiment, when the determination unit 21 detects that water has reached the flood detection units 11, 13, it determines that there is a sign of flooding of the engine 110 or the battery 120. Furthermore, when the determination unit 21 detects that water has reached the flood detection units 12, 14, it determines that the engine 110 or the battery 120 has been flooded.

[0034] In addition, the judgment unit 21 may store information regarding the type of equipment (engine 110, battery 120) targeted by the flood detection units 11-14 and the positional relationship between the equipment and the flood detection units 11-14 in a memory unit not shown, or may obtain the information from the detection unit 10 together with the detection results.

[0035] The output control unit 22 is a functional unit that outputs to the output unit 30 instructions to control the operation of the output unit 30 based on the determination result by the determination unit 21. The output control unit 22 outputs different instructions depending on whether the determination unit 21 determines that there is a sign of flooding in the equipment or whether the equipment is flooded. In this embodiment, when the determination unit 21 determines that there is a sign of flooding, the output control unit 22 outputs a flood occurrence alarm that warns of the sign of flooding. Furthermore, when the determination unit 21 determines that flooding has occurred, the output control unit 22 outputs a flood occurrence alarm that warns of flooding.

[0036] The control unit 20 may be configured by a single information processing device, or may be configured by a plurality of information processing devices distributed on a communication network. The control unit 20 may be provided at a location different from the vehicle 100 in which the detection unit 10 and the output unit 30 are mounted, or may be mounted on the vehicle together with the detection unit 10 and the output unit 30. The control unit 20 and the output unit 30 may be realized by a single hardware configuration. The control unit 20 may include other configurations that are generally included in a server device, in addition to the main hardware configurations such as a CPU (Central Processing Unit), a communication device, and a storage device.

[0037] The output unit 30 mainly has an alarm light 31, a speaker 32, and a communication module 33. The output unit 30 is a functional unit that performs various operations in response to flooding based on control commands from the control unit 20.

[0038] The output unit 30 is capable of issuing multiple types of warnings based on control commands from the output control unit 22. For example, the output unit 30 outputs a warning in a different manner depending on the determination result of the determination unit 21, depending on whether it is determined that there is a sign of flooding (flood pre-warning) or that flooding has occurred (flood occurrence warning).

[0039] The warning light 31 is an indicator such as a lamp provided on the vehicle 100, and is visible from inside or outside the vehicle 100. The warning light 31 issues a warning in a number of different modes based on the determination result of the determination unit 21. For example, the warning light 31 may issue a warning by lighting or blinking in a different color for a flood pre-warning and a flood occurrence warning (for example, yellow for a flood pre-warning and red for a flood occurrence warning). In addition, for example, the warning light 31 may issue a warning in a different mode (light intensity or blinking pattern) for a flood pre-warning and a flood occurrence warning. In addition, the warning light 31 may have a display and be configured to display different characters for a flood pre-warning and a flood occurrence warning.

[0040] The speaker 32 is provided in the vehicle 100 and can emit a sound toward the inside or outside of the vehicle 100. The speaker 32 issues an alarm in a number of different manners based on the determination result of the determination unit 21. For example, the speaker 32 may issue an alarm by changing the notification sound, voice, message content, etc., between a pre-flooding alarm and a flood occurrence alarm.

[0041] The communication module 33 is a functional unit that communicates with, for example, an external device and transmits an alarm. The communication module 33 may be provided in the vehicle 100, or may be provided in the control unit 20. The communication module 33 may transmit an email to a terminal of a user of the vehicle 100, for example, or may notify a message to a terminal of an administrator by using an appropriate technology such as short-range communication.

[0042] The communication module 33 issues an alert in a number of different ways based on the determination result of the determination unit 21. For example, the communication module 33 may send emails or appropriate messages with different content for a pre-flooding alert and a flooding alert, or may send the alerts to different destinations. This configuration allows the user to more clearly understand the status of the vehicle 100.

[0043] Here, the flow of a process in which the water intrusion detection system 1 issues an alarm will be described with reference to FIG. Fig. 4 is a flowchart showing an example of the flow of warning processing by the water inundation detection system 1. The processing in Fig. 4 is performed continuously and repeatedly, for example, while the electronic devices of the vehicle 100 are in operation.

[0044] (Step SP11) The control unit 20 (here, the determination unit 21) acquires the right result from the detection unit 10 and determines whether or not flooding has been detected by the flooding detection units 11, 13 provided at the bottom ends of the devices (engine 110, battery 120). If flooding has been detected by the flooding detection units 11, 13 (Yes in step SP11), the control unit 20 advances the process to step SP13. If flooding has not been detected by the flooding detection units 11, 13 (No in step SP11), the control unit 20 ends the process.

[0045] (Step SP13) The control unit 20 (here, the output control unit 22) outputs an instruction to output a flood pre-warning to the output unit 30 based on the determination result by the determination unit 21, and the output unit 30 acquires this instruction. Then, the output unit 30 issues a flood pre-warning that warns of signs of flooding by at least one of the warning light 31, the speaker 32, and the communication module 33. The control unit 20 proceeds to step SP15.

[0046] (Step SP15) The control unit 20 (here, the determination unit 21) acquires the detection result from the detection unit 10 and determines whether or not flooding has been detected by the flooding detection units 12, 14 provided at the upper ends of the devices (engine 110, battery 120). If flooding has been detected by the flooding detection units 12, 14 (Yes in step SP15), the control unit 20 advances the process to step SP17. If flooding has not been detected by the flooding detection units 12, 14 (No in step SP15), the control unit 20 ends the process.

[0047] (Step SP15) The control unit 20 (here, the output control unit 22) outputs the result of the determination by the determination unit 21 to the output unit 30, and the output unit 30 acquires the result of the determination by the determination unit 21, i.e., that flooding has been detected by the water flood detection units 12, 14. The output unit 30 then issues a water flood occurrence alarm to warn of water flooding using at least one of the alarm light 31, speaker 32, and communication module 33. The water flood detection system 1 then ends the series of processes.

[0048] It should be noted that the order of steps can be changed as appropriate in the process flow shown in Fig. 4. For example, steps SP13 and SP15 may be performed simultaneously.

[0049] According to this embodiment, the user can clearly grasp the status of the vehicle. Therefore, when water has entered the interior of the vehicle or there is a risk of water entering the interior of the vehicle, it is possible to prevent serious breakdown of the vehicle 100 due to careless handling, such as starting the engine 110. Furthermore, when a water inundation advance warning is notified, the user can take evacuating action to prevent further water inundation. Furthermore, when a water inundation occurrence warning is notified, the user can stop driving. In this way, breakdown of the vehicle 100 and the safety of the driver can be ensured when water has entered the interior of the vehicle 100.

[0050] In this embodiment, when the judgment unit 21 detects that water has reached the flood detection units 11 and 13, it judges that there are signs of flooding of the engine 110 or the battery 120, and when the judgment unit 21 detects that water has reached the flood detection units 12 and 14, it judges that the engine 110 or the battery 120 has been flooded, but the method by which the judgment unit 21 judges whether or not there are signs of flooding is not limited to this.

[0051] For example, the determination unit 21 may make a determination regarding flooding based on the detection results of paired flooding detection units provided for the same equipment. For example, when the determination unit 21 detects that water has reached the flooding detection unit 12 provided at the upper end of the engine 110, but does not detect that water has reached the flooding detection unit 11 (provided at the lower end of the engine 110) that is paired with the flooding detection unit 12, the determination unit 21 may regard this as a false detection and not make a determination that flooding has occurred. This can increase the accuracy of detection.

[0052] Also, for example, the determination unit 21 may make a determination regarding flooding based on the detection results of all flooding detection units provided for a plurality of devices. For example, when the determination unit 21 does not detect that water has reached the lowest flooding detection unit (here, flooding detection unit 13) based on the heights of the flooding detection units 11-14 provided in the vehicle 100, the determination unit 21 may not determine that there is a sign of flooding or that flooding has occurred even if it detects that water has reached the other flooding detection units (here, flooding detection units 11, 12, 14). This can increase the accuracy of detection.

[0053] In the present embodiment, the output unit 30 issues an alarm when the determination unit 21 determines that flooding has occurred, but the timing of issuing the alarm from the output unit 30 is not limited to this. For example, the determination result by the determination unit 21 may be output to the output unit 30 in response to an input from a user such as a driver or manager of the vehicle. In this case, the control unit 20 has a storage unit and a reception unit that receives input, and the detection result acquired from the detection unit 10 or the determination result by the determination unit 21 is stored in the storage unit, and when the reception unit receives the input, the output control unit 22 outputs the result stored in the storage unit to the output unit 30. The operation input from the user may be, for example, a command to display the detection history, or an appropriate operation leading to the start of operation, such as an operation to turn on the vehicle 100. This allows the user to grasp the flooding situation in detail even at a desired timing other than when flooding has been determined.

[0054] Since starting to drive when there is a history of flooding may lead to an accident or breakdown of the vehicle 100, it is desirable that the detection result be transmitted from the control unit 20 to the output unit 30 by any of the actions leading up to the start of driving. With this configuration, even if the user does not check the notification at the time of flooding, careless handling after flooding can be more reliably prevented.

[0055] In addition, in this embodiment, there are two devices (engine 110 and battery 120), and each device has two water submersion detection units 11 to 14 in total, but the number of devices is not limited to two, and the number of water submersion detection units is not limited to four.

[0056] <Second embodiment> Next, a water submersion detection system 2 according to a second embodiment will be described. The water inundation detection system 2 has the same elements and structure as the water inundation detection system 1 according to the first embodiment. Therefore, in the following description, the same elements and structure as those in the water inundation detection system 1 according to the first embodiment are denoted by the same reference numerals and detailed description is omitted, and only the parts that differ from the first embodiment will be described.

[0057] The water flooding detection system 2 differs from the water flooding detection system 1 according to the first embodiment in that it works in conjunction with an air suspension provided on the vehicle 100, and raises the vehicle height via the air suspension when water flooding is detected.

[0058] 5 is a functional block diagram showing an example of the functional configuration of a water intrusion detection system 2 according to the second embodiment. The water intrusion detection system 2 mainly includes a detection unit 10, a control unit 20A, and an output unit 30A. The detection unit 10, the control unit 20A, and the output unit 30A are configured to be able to communicate with each other via wired or wireless communication.

[0059] The output unit 30A is a functional unit that performs various operations in response to flooding based on control commands from the control unit 20A, similar to the output unit 30. The output unit 30A mainly has a warning light 31, a speaker 32, a communication module 33, and an air suspension 34.

[0060] The air suspension 34 is provided on the vehicle 100 and adjusts the vehicle height of the vehicle 100 equipped with the water inundation detection system 2. A known air suspension installed on various vehicles may be used as the air suspension 34. For example, the air suspension 34 may have an actuator, and the vehicle height may be raised and lowered by raising and lowering an upper seat portion using the actuator.

[0061] The control unit 20A mainly has various functional units, such as a determination unit 21 and an output control unit 22A, as software resources. The output control unit 22A is different from the output control unit 22 in that it outputs instructions to the air suspension 34, but is otherwise similar to the output control unit 22.

[0062] Fig. 6 is a flowchart showing an example of the flow of processing by the water inundation detection system 2. The processing in Fig. 6 is performed continuously and repeatedly, for example, while the electronic devices of the vehicle 100 are in operation. Steps SP11 and SP13 are similar to those of the water intrusion detection system 1 described with reference to Fig. 4. After step SP13, the control unit advances the process to step SP14.

[0063] (Step SP14) Based on the result of the determination by the determination unit 21 (determination that there is a sign of flooding), the control unit 20A (here, the output control unit 22A) outputs a control command to the air suspension 34 to increase the vehicle height of the vehicle 100. The air suspension 34 receives this command and increases the vehicle height of the vehicle 100. The control unit 20 advances the process to step SP15.

[0064] Steps SP15 and SP17 are similar to those in the water intrusion detection system 1 described with reference to FIG.

[0065] According to this embodiment, by raising the vehicle height when a sign of flooding is detected, flooding of the equipment (engine 110, battery 120) can be prevented in advance.

[0066] In this embodiment, a flood advance warning is issued and the vehicle height of the vehicle 100 is raised. However, instead of issuing a flood advance warning, the vehicle height of the vehicle 100 may be raised.

[0067] In the present embodiment, the vehicle height of the vehicle 100 is raised via the air suspension 34 when flooding is detected by the flooding detection units 11 and 13, but the timing for raising the vehicle height of the vehicle 100 is not limited to this. For example, the output control unit 22A may output an instruction to the air suspension 34 to raise the vehicle height of the vehicle 100 when flooding is detected by the flooding detection units 11 and 13 and when flooding is detected by the flooding detection units 12 and 14. In this case, the output control unit 22A may output an instruction to the air suspension 34 to raise the vehicle height of the vehicle 100 by an arbitrary value that does not interfere with driving when flooding is detected by the flooding detection units 11 and 13, and may output an instruction to the air suspension 34 to raise the vehicle height of the vehicle 100 to the maximum extent when flooding is detected by the flooding detection units 12 and 13. This makes it possible to reduce the risk of flooding and to drive the vehicle 100 while preventing equipment from being submerged in water for a long period of time.
