  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of an electric vehicle equipped with an in-vehicle device to which the present invention is applied.

  The electric vehicle 1 is a vehicle in which a motor is driven by electric power stored in a secondary battery. For this purpose, a high voltage battery 12 used as a driving power source and driving power for electrical components and a low voltage battery 13 for assisting power supply to the electrical components are mounted inside the electric vehicle 1.

  In addition, the electric vehicle 1 is equipped with an in-vehicle device (an in-vehicle device 31 in FIG. 3) for countermeasures against submersion or inundation, for example, when it is submerged or submerged due to an unexpected accident or the like. This in-vehicle device performs predetermined measures such as forcibly opening a power window so that a passenger can easily escape outside the vehicle when submerged or flooded.

  In the electric vehicle 1, there are two cases that require countermeasures against submersion: the case where the electric vehicle 1 is submerged and the case where the electric vehicle 1 is submerged. Here, submergence means that the electric vehicle 1 on the ground sinks in the sea or lake due to an unexpected accident or the like. Moreover, the flooding means that the electric vehicle 1 is immersed in water due to a flood or the like, and water enters the inside thereof. Since the vehicle-mounted device to which the present invention is applied can be used for countermeasures against both submersion and flooding, the countermeasures for both flooding and flooding will be described below.

The vehicle device, to the sensor 11 ₁ for submersion / immersion detection for detecting submergence or flooding has 11 _4, the sensors are attached to predetermined positions of the vehicle body of the electric vehicle 1. For example, the submersion / flooding detection sensors 11 ₁ to 11 ₃ are attached at positions closer to the road surface at the lower part of the vehicle body, and detect whether the vehicle body of the electric vehicle 1 is submerged or flooded. Further, submersion / immersion detecting sensor 11 _4, such as the lower electrode terminals of the high voltage battery 12, mounted in a position where it can detect the state immediately before the electrode terminal is wetted detects submersion or immersion of the high-voltage battery 12.

That is, the submerged / immersion to detection sensor 11 ₁ 11 _3, the body part of submergence or flooding of the electric vehicle 1 is detected by submersion / immersion detection sensor 11 _4, is submerged or flooded high-voltage battery 12 detected Is done.

  Moreover, as shown in FIG. 1, since the low voltage battery 13 is installed on the upper part of the high voltage battery 12, even after the high voltage battery 12 is submerged or submerged, it does not submerge for a certain period of time. Electric power can be supplied.

In the present embodiment, submersion / immersion detection sensor 11 ₁ to 11 _4, it is assumed to attach to the position shown in FIG. 1, is submerged or flooded part of the body of the electric vehicle 1 and the high voltage battery 12 If it can be detected, it can be attached to another position. The number of submersion / immersion detection sensors 11 is not limited to four. For example, by attaching a larger number of sensors, it is possible to increase the accuracy of detection of submersion or submersion.

  Next, the internal configuration of the electric vehicle 1 of FIG. 1 will be described with reference to FIG.

  The electric vehicle 1 includes an in-vehicle charger 21, a BMU (Battery Management Unit) 22, a DC / DC converter 23, a capacitor 24, and an ECU (Electronic Control Unit) 25 in addition to the high voltage battery 12 and the low voltage battery 13 shown in FIG. The inverter 26 and the motor 27 are included.

  The high-voltage battery 12 is charged with electric power by charging using a household power source by the in-vehicle charger 21 or by quick charging by a quick charging device (not shown) provided in an external electric vehicle charging facility. . Further, in the vicinity of the high voltage battery 12, a BMU 22 connected to the in-vehicle charger 21 or the quick charging device by CAN is provided. The BMU 22 adjusts the temperature of the high voltage battery 12.

  The electric power charged in the high-voltage battery 12 is supplied to an ECU 25 or the like that controls electronic devices such as electrical components in the electric vehicle 1 via the DC / DC converter 23, and these electrical components and the like are driven. That is, in this case, the electric power from the high voltage battery 12 is the driving electric power for the electrical components. Moreover, the electric power stored in the low voltage battery 13 is supplied to the ECU 25 and the like to assist the electric power supply of the electrical components.

  The capacitor 24 is a 12V capacitor, for example, and stores the electric power from the high voltage battery 12 via the DC / DC converter 23. The electric power stored in the capacitor 24 is supplied to the ECU 25 and the like.

  The electric power from the high voltage battery 12 is supplied to the inverter 26 that drives the motor 27. When the motor 27 is driven by the inverter 26, the tire is driven by the motor 27 and the electric vehicle 1 travels. That is, in this case, the electric power from the high voltage battery 12 becomes a travel drive source.

  Next, with reference to FIG. 3, the structural example of the vehicle-mounted apparatus mounted on the electric vehicle 1 for submersion or flooding countermeasures will be described.

Vehicle device 31, in addition to the to the sensor 11 ₁ for submersion / immersion detection described above 11 _4, and a capacitor 24, the sensor control unit 41, submersion / immersion countermeasure 42, and structured to include a battery control unit 43. In FIG. 3, the high voltage battery 12 and the low voltage battery 13 controlled by the battery control unit 43 are also illustrated for easy understanding.

The sensor control unit 41, submersion / immersion detection sensor 11 ₁ to control the 11 _4. The sensor control unit 41, the detection results obtained by submersion / immersion to detection sensor 11 ₁ 11 _4, and supplies the submersion / immersion countermeasure 42.

The submersion / flooding countermeasure unit 42 controls the battery control unit 43 to acquire the state of the high voltage battery 12 or the state of the low voltage battery 13. Submersion / immersion countermeasure unit 42 to the sensor 11 ₁ for submersion / immersion detection supplied from the sensor control unit 41 11 ₄ by the detection result, and the state or the low-voltage battery 13 of the high voltage battery 12 supplied from the battery controller 43 Based on the state, a predetermined countermeasure is taken against the passenger of the electric vehicle 1 or a person around it.

  The battery control unit 43 controls the high voltage battery 12, the low voltage battery 13, and the capacitor 24 according to the control of the submergence / flooding countermeasure unit 42.

  The in-vehicle device 31 is configured as described above.

  Next, the operation of the in-vehicle device 31 will be described.

  By the way, as mentioned above, the vehicle-mounted device 31 to which the present invention is applied can be used for both submergence and flooding countermeasures, but as a case where the electric vehicle 1 is submerged or submerged, it is running and parked. You could think so. Therefore, in the present embodiment, an example in which the traveling electric vehicle 1 is submerged will be described as the first case, and an example in which the electric vehicle 1 being parked will be submerged as the second case. explain.

  First, with reference to the flowchart of FIG. 4, the submergence detection countermeasure process in the traveling electric vehicle 1, which is the first case described above, will be described.

For example, when a predetermined operation is performed by a driver who has boarded the electric vehicle 1, the vehicle-mounted device 31 is powered on in step S11. Then, the sensor controller 41 determines, in step S12, submerged / to detecting water sensor 11 ₁ and checked for proper operation 11 _4, whether the operation of the sensors is normal.

  If it is determined in step S12 that the operation of each sensor is normal, the process proceeds to step S13. And the vehicle-mounted apparatus 31 starts a submergence detection process, and the electric vehicle 1 operate | moves in a submergence detection mode. Details of the operation of the in-vehicle device 31 in the submergence detection mode will be described later with reference to the flowchart of FIG.

  On the other hand, when it is determined in step S12 that the operation of each sensor is abnormal, in step S14, the sensor control unit 41 notifies the driver that the submergence sensor is unusable by a predetermined means. The process proceeds to step S15. In this case, since the in-vehicle device 31 does not execute the submergence detection process, the electric vehicle 1 operates in the normal operation mode in which the countermeasure for submergence detection is not performed.

  As described above, the electric vehicle 1 operates in either the submergence detection mode or the normal operation mode based on the result of operation confirmation of each sensor.

  Next, the details of the operation of the in-vehicle device 31 in the submergence detection mode corresponding to the process of step S13 of FIG. 4 will be described with reference to the flowchart of FIG.

In step S <b> 21, the sensor control unit 41 determines whether or not a part of the vehicle body of the electric vehicle 1 has been submerged based on the detection result supplied from the submersion / flooding detection sensors 11 ₁ to 11 _3. .

  If it is determined in step S21 that a part of the vehicle body is not submerged, it is determined in step S22 whether or not the system of the electric vehicle 1 is powered off. If it is determined in step S22 that the power has been turned off, the traveling of the electric vehicle 1 has been completed. Therefore, the processing returns to the processing of step S13 in FIG. 4, and the submergence detection countermeasure processing during traveling in FIG.

  On the other hand, if it is determined in step S22 that the power is not turned off, the process returns to step S21, and the processes of steps S21 and S22 are repeated until it is determined that a part of the vehicle body is submerged. That is, while the electric vehicle 1 is traveling on the ground, these determination processes are continuously executed.

  If it is determined in step S21 that a part of the vehicle body has been submerged, the process proceeds to step S23. Then, the in-vehicle device 31 starts the submergence countermeasure process, and the electric vehicle 1 operates in the submergence countermeasure mode. Details of the operation of the in-vehicle device 31 in the submergence countermeasure mode will be described later with reference to the flowchart of FIG.

As described above, the electric vehicle 1 is submerged until the submersion / inundation detection sensors 11 ₁ to 11 ₃ detect submersion of a part of the vehicle body, for example, by sinking into the sea due to an accident. It operates in the detection mode, and then transitions to the submergence countermeasure mode when a part of the body is submerged.

  Next, with reference to the flowchart of FIG. 6, the detail of operation | movement of the vehicle equipment 31 in the submergence countermeasure mode corresponding to the process of step S23 of FIG. 5 is demonstrated.

  In step S31, the submergence / flooding countermeasure unit 42 outputs a sound such as “sunk in the sea” to notify the driver and other passengers that the vehicle is in a dangerous state. Inform.

In step S32, submersion / immersion countermeasure unit 42 based on the detection result of submergence / detecting water sensor 11 ₄ disposed in the vicinity of the high voltage battery 12, determines whether the high-voltage battery 12 is submerged.

  If it is determined in step S32 that the high voltage battery 12 has been submerged, the submersion / flooding countermeasure unit 42 controls the battery control unit 43 to block the high voltage battery 12 in step S33.

  FIG. 7 is a diagram illustrating an example of a method for shutting off the high-voltage battery 12.

  In FIG. 7, two types of circuit symbols indicating the high voltage battery 12 are described. The upper circuit symbol indicates a case where the high voltage battery 12 is normal, and the lower circuit symbol indicates the high voltage battery 12. The case when it is shut off is shown.

  That is, the battery control unit 43 shuts off the high-voltage battery 12 by destroying the intermediate bus bar provided in the normal high-voltage battery 12 so that the high-voltage battery 12 is in the state of being shut off.

Returning to the flowchart of FIG. 6, if it is determined in step S32 that the high voltage battery 12 is not submerged, the water level exceeds the level of the submersion / immersion detection sensors 11 ₁ to 11 ₃ , but since up to the level of the detecting sensor 11 ₄ is not reached, skips the processing of steps S33, here, it is not to block the high-voltage battery 12.

  In step S <b> 34, the submersion / flooding countermeasure unit 42 controls the battery control unit 43 to acquire information indicating the state of the low voltage battery 13, so that the SOC (State Of Charging) state indicating the remaining capacity of the low voltage battery 13 is established. It is determined whether or not it is below a certain value.

  If it is determined in step S34 that the SOC state of the low voltage battery 13 is equal to or lower than a certain value, the low voltage battery 13 cannot be used. Therefore, in step S35, the submergence / flooding countermeasure unit 42 performs the above-described step S33. It is determined whether or not the high voltage battery 12 has been shut off by the processing.

  If it is determined in step S35 that the high voltage battery 12 has not been cut off, the high voltage battery 12 can still be used. Therefore, in step S36, the submergence / flooding countermeasure unit 42 is either the simple countermeasure 1 or the submergence countermeasure 1. Select one of the measures.

  When the simple measure 1 is selected as a measure in step S36, the simple measure 1 is executed by the submergence / flooding countermeasure unit 42 in steps S37 to S39.

  That is, the submergence / flooding countermeasure unit 42 controls the battery control unit 43 to charge the capacitor 24 with the electric power from the high voltage battery 12 via the DC / DC converter 23 in step S37. After the end, in step S38, the high voltage battery 12 is shut off. This blocking method is the same as the method shown in FIG.

  Then, the submergence / flooding countermeasure unit 42 performs the simple countermeasure 1 using the electric power charged in the capacitor 24 in step S39. As the simple measure 1, since the power charged in the capacitor 24 is limited, a simple measure that can be executed with low power consumption is taken. Specific examples include measures such as outputting a message prompting you to escape from the car, such as “Please break the window to escape.” Or display these messages on the display of the car navigation system. Is executed.

  On the other hand, if the submersion countermeasure 1 is selected as a countermeasure in step S36, the submersion countermeasure 1 is executed by the submersion / flooding countermeasure section 42 in steps S40 and S41.

  That is, in step S40, the submersion / flooding countermeasure unit 42 controls the battery control unit 43 to output the electric power from the high voltage battery 12 to the ECU 25 via the DC / DC converter 23. Thus, it is possible to perform the submersion countermeasure 1 for a certain time. Since the power from the high-voltage battery 12 is used as the submersion countermeasure 1, a countermeasure that consumes more power than the simple countermeasure 1 can be performed. Specifically, for example, the power window is forcibly opened, the user is prompted to escape from the interior by voice output or screen display, the submersion is notified to the surroundings of the electric vehicle 1, or the person existing around the surroundings. Measures such as notification of progress of submersion / flooding measures such as notification of requesting help or notification indicating that the high-voltage battery 12 has been shut off are executed.

  Thereafter, in step S41, the high voltage battery 12 is shut off by, for example, the shutoff method shown in FIG.

  If it is determined in step S35 that the high voltage battery 12 has been shut off, the simple countermeasure 2 is executed by the submergence / flooding countermeasure unit 42 in step S42.

  That is, in this case, since the high voltage battery 12 has already been shut off and the SOC state of the low voltage battery 13 is below a certain value, only limited power can be supplied. Therefore, in this simple measure 2, a measure that can be performed with more limited power consumption than the above simple measure 1 is executed. Specifically, for example, measures such as prompting escape from the vehicle are executed only by displaying such as turning on an indicator lamp for notifying submergence.

  Furthermore, when it is determined in the above step S34 that the SOC state of the low voltage battery 13 exceeds a certain value, the low voltage battery 13 can be used. Therefore, the submersion countermeasure 2 is executed in steps S43 and S44. Is done.

  That is, when the low voltage battery 13 can be used, it is considered that the high voltage battery 12 is disconnected or not blocked. Therefore, the submergence / flooding countermeasure unit 42 first selects the high voltage in step S43. When the battery 12 is not cut off, the high voltage battery 12 is cut off by the blocking method shown in FIG. 7, for example.

  Thereby, since the high voltage battery 12 can no longer be used, the submergence / flooding countermeasure unit 42 performs the submergence countermeasure 2 using the electric power from the low voltage battery 13 in step S44. As the submergence countermeasure 2, since the electric power from the low voltage battery 13 whose remaining capacity exceeds a predetermined value is used, it is possible to take a countermeasure that consumes more electric power than the above simple countermeasure 1. Specifically, for example, the power window is forcibly opened, the user is prompted to escape from the vehicle by sound output or screen display, or a message indicating that the high voltage battery 12 is shut off is notified. Such measures are taken.

  When the processing of each countermeasure in step S39, S41, S42, or S44 ends, the submergence countermeasure mode in FIG. 6 ends, and the processing returns to the processing in step S23 in FIG. 5, and then further, in step S13 in FIG. Returning to the process, the submergence detection countermeasure process in the traveling electric vehicle 1 in FIG. 4 ends.

  As described above, in the in-vehicle device 31, the simple measures 1 and 2 or the submersion measures 1 and 2 are performed according to the state of the high-voltage battery 12 and the state of the low-voltage battery 13. Even when submerged, the safety of the passenger is ensured by such measures.

  Next, with reference to the flowchart of FIG. 8, the flood detection detection process in the parked electric vehicle 1 as the second case will be described.

In this second case, since the electric vehicle 1 is parked, when the system of the electric vehicle 1 is turned off in step S11, the sensor is detected in steps S52 to S55 as in steps S12 to S15 in FIG. The controller 41 confirms the operation of the submersion / immersion detection sensors 11 ₁ to 11 ₄ . The electric vehicle 1 operates in the flood detection mode when the operation of each sensor is normal, and operates in the normal parking mode when the operation of each sensor is abnormal.

  Here, with reference to the flowchart of FIG. 9, the detail of operation | movement of the vehicle equipment 31 in the inundation detection mode corresponding to the process of step S53 of FIG. 8 is demonstrated.

In step S61 to S63, similarly to steps S21 through S23 in FIG. 5, submerging / flooding to detection sensor 11 ₁ based on the detection result supplied from the 11 _3, the vehicle body of the electric vehicle 1 of the flooding to some If it is determined that inundation of a part of the vehicle body has been detected in step S61, the electric vehicle 1 operates in the inundation countermeasure mode (processing in step S63).

  Here, with reference to the flowchart of FIG. 10, the detail of operation | movement of the vehicle-mounted apparatus 31 in the flooding countermeasure mode corresponding to the process of step S63 of FIG. 9 is demonstrated.

  In steps S71 to S75, as in steps S31 to S35 of FIG. 6, after the danger of flooding is notified to the surroundings, each process for determining the state of the high voltage battery 12 and the low voltage battery 13 is performed. When flooded, the high voltage battery 12 is shut off.

  In step S <b> 76, the submersion / flooding countermeasure unit 42 selects one of the simple countermeasure 3 and the flooding countermeasure 1.

  When the simple measure 3 is selected as a measure in step S76, the simple measure 3 is executed by the submergence / flooding countermeasure unit 42 in steps S77 to S79.

  That is, the submergence / flooding countermeasure unit 42 charges the capacitor 24 with the electric power from the high voltage battery 12 in steps S77 and S78, and then shuts off the high voltage battery 12, as in steps S37 and S38 of FIG.

  Then, the submersion / flooding countermeasure unit 42 performs the simple countermeasure 3 using the electric power charged in the capacitor 24 in step S79. As the simple measure 1, since the power charged in the capacitor 24 is limited, a simple measure that can be executed with low power consumption is taken. Specifically, for example, a measure for notifying that the electric vehicle 1 is in danger of being inundated by executing an audio output from a speaker or a display on a display unit of a car navigation system is executed.

  On the other hand, when the flood countermeasure 1 is selected as the countermeasure in step S76, the flood countermeasure 1 is executed by the submersion / flood countermeasure section 42 in steps S80 and S81.

  That is, in steps S80 and S81, as in steps S40 and S41 of FIG. 6, the submersion / flooding countermeasure unit 42 controls the battery control unit 43 to output power from the high voltage battery 12 to the ECU 25. The ECU 25 performs the flood countermeasure 1 for a predetermined time. Since the power from the high voltage battery 12 is used as the flood countermeasure 1, it is possible to take a countermeasure that consumes more power than the simple countermeasure 3 described above. Specifically, for example, the electric vehicle 1 is inundated and dangerous for persons around the parked electric vehicle 1 (for example, passengers or passersby in other vehicles in the parking lot). To that end, measures are taken to notify the user by voice output from the speaker, lighting of a lamp such as an LED (Light Emitting Diode) or a headlight, or a notification indicating whether or not the high voltage battery 12 has been shut off. Further, for example, a measure such as leaving a history indicating that the high-voltage battery 12 has been shut off intuitively may be executed by raising a flag.

  If it is determined in step S75 that the high voltage battery 12 has been shut off, the simple countermeasure 4 is executed by the submergence / flooding countermeasure unit 42 in step S82.

  That is, in this case, as in step S42 of FIG. 6, since the high voltage battery 12 has already been shut off and the SOC state of the low voltage battery 13 is below a certain value, only limited power can be supplied. Therefore, in this simple measure 4, a measure that can be performed with more limited power consumption than the above simple measure 3 is executed. Specifically, for example, a measure that can notify the surroundings of a danger by a simple mechanism such as raising a flag is executed.

  Further, when it is determined in step S74 that the SOC state of the low voltage battery 13 exceeds a certain value, the low voltage battery 13 can be used, and therefore, the flood countermeasure 2 is executed in steps S83 and S84. .

  That is, in this case, similarly to steps S43 and S44 of FIG. 6, when the high voltage battery 12 is not cut off, the high voltage battery 12 is cut off, and then the submersion countermeasure 2 using the electric power from the low voltage battery 13 is used. Is done. As the inundation countermeasure 2, since the electric power from the low voltage battery 13 whose remaining capacity exceeds a predetermined value is used, a countermeasure that consumes more electric power than the above simple countermeasure 3 can be performed. Specifically, such as forcibly opening the power window, prompting escape from the vehicle by voice output or screen display, or notifying that the high voltage battery 12 has been shut off is safe. Countermeasures are implemented.

  When the processing of each countermeasure in step S79, S81, S82, or S84 is completed, the inundation countermeasure mode in FIG. 10 is terminated, and the processing returns to step S63 in FIG. Returning to FIG. 8, the inundation detection countermeasure process in the parked electric vehicle 1 is completed.

  As described above, in the in-vehicle device 31, the simple measures 3 and 4 or the flooding measures 1 and 2 are performed according to the state of the high voltage battery 12 and the state of the low voltage battery 13. Even if it is flooded, the safety of the passenger is ensured by these measures.

  Although it is conceivable that the electric vehicle 1 is submerged during traveling or submerged during parking, these cases are the same as those described in the first case and the second case described above. Is omitted.

  As described above, according to the present invention, when an electric vehicle is submerged or submerged, it is possible to escape from the vehicle after ensuring the safety in consideration of the state of the battery. Moreover, the safety | security of the person who is the circumference | surroundings can be ensured also about the submergence or flooding which generate | occur | produced in the parked electric vehicle.
