Description

[Technical Field]

[0001] The present disclosure relates to a vehicle that can ensure the safety of infants, children, and the like who are left inside the vehicle. [Background technology]

[0002] When drivers get out of their cars or buses, they often leave infants or children behind in the vehicle, causing the infants and children to become dangerously ill and, in the worst cases, even lose their lives.

[0003] To prevent such accidents, a technology has been proposed that, when an abandoned vehicle is detected, notifies the driver and rescue organizations that can respond to the abandoned vehicle, as described in Patent Document 1, for example.

[0004] Furthermore, as described in Patent Document 2, for example, a technology has been proposed in which, when an abandonment is detected, in addition to notifying the driver, etc., the air conditioner, etc. is turned on to improve the in-car environment and ensure the safety of infants and children who have been left behind. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-004242 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-147105 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the method of notifying the driver, there is a risk that the driver may not notice the notification. Also, with the method of notifying the rescue organization, there is a risk that the rescue organization will have to make frequent rescue dispatches. Since rescue organizations are almost always public organizations, frequent dispatches for rescue may be a significant social burden.

[0007] Furthermore, when operating an air conditioner or the like, the operating time of the air conditioner is dependent on the remaining amount of battery or gasoline, and it is not necessarily possible to maintain a comfortable in-vehicle environment for a long period of time.

[0008] As such, existing measures to prevent abandonment do not fully take into account the capabilities of the vehicle and those around it, and there is thought to be room for improvement.

[0009] The present disclosure provides a vehicle that can rescue infants, children, etc. left behind inside the vehicle more accurately and safely than conventional vehicles. [Means for solving the problem]

[0010] One aspect of the vehicle of the present disclosure is an abandoned person detection unit that detects whether or not a person has been abandoned in the vehicle; a life extension control unit that, when the abandonment detection unit detects abandonment, activates a plurality of life extension related units of the vehicle in stages according to the elapsed time of abandonment; Equipped with. [Effects of the Invention]

[0011] According to the present disclosure, infants, children, etc. left behind in a vehicle can be rescued more accurately and safely than conventional methods. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 1 is a block diagram showing a configuration of a vehicle according to an embodiment of the present invention; [Figure 2] 1 is a flowchart showing a flow of life extension control in a vehicle according to an embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0014] 1 is a block diagram showing the configuration of a vehicle 100 according to an embodiment of the present disclosure. The vehicle 100 is a passenger car, a bus, or the like.

[0015] The vehicle 100 has a vehicle state determination unit 101, an interior detection unit 102, a driver detection unit 103, an interior comfort determination unit 104, a life extension control unit 110, a notification unit 105, an air conditioner operation unit 106, a window opening operation unit 107, a door lock / door opening operation unit 108, and an emergency service notification unit 109.

[0016] The vehicle state determination unit 101 receives vehicle speed information, timer information, door information, and side parking (side P) information, and determines whether the vehicle 100 is in a parked state based on this information. For example, the vehicle state determination unit 101 determines that the vehicle 100 is in a parked state when 10 minutes or more have passed since the vehicle speed reached 0 km / h, all doors are closed, and the side parking is activated.

[0017] The vehicle interior detection unit 102 receives all seat information from the camera 102a and the sensor 102b, and determines whether or not there is a person in the vehicle based on this information.

[0018] The driver detection unit 103 determines whether or not there is a person in the driver's seat based on information from the camera 103a.

[0019] The vehicle interior comfort determination unit 104 receives input of vehicle interior temperature information, vehicle interior humidity information, vehicle interior sunlight information, and vehicle interior sound information, and determines vehicle interior comfort based on these.

[0020] As an example, the vehicle interior comfort determination unit 104 determines the vehicle interior comfort based on the following. <1> Temperature must be below 22°C and humidity must be below 55% (to determine coldness) <2> Temperature must be above 28°C and humidity must be above 60% (to judge heat) <3> Illuminance must exceed 10,000lx (direct sunlight), <4> The existence of a 4000Hz sound (a baby's cry),

[0021] The in-vehicle comfort determination unit 104 determines, for example, <1> ~ <4> If any of the above is detected, it is determined that the interior of the vehicle is not comfortable.

[0022] The life extension control unit 110 controls the notification unit 105, air conditioner operation unit 106, window opening operation unit 107, door lock / door opening operation unit 108 and rescue agency notification unit 109 as life extension related units based on outputs from the vehicle state determination unit 101, the interior detection unit 102, the driver detection unit 103 and the interior comfort determination unit 104.

[0023] The life extension control unit 110 mainly includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU reads a program corresponding to the processing content from the ROM and loads it into the RAM, and in cooperation with the loaded program, performs centralized control of the operations of the notification unit 105, the air conditioner operation unit 106, the window opening operation unit 107, the door lock / door opening operation unit 108, and the rescue service notification unit 109. Note that all or part of the life extension control unit 110 may be formed by a hardwired circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). Control by the life extension control unit 110 will be described in detail later.

[0024] The notification unit 105 notifies people around the vehicle 100 and the driver of the vehicle 100 that an abandoned vehicle has occurred, based on a control signal from the life extension control unit 110. For example, when the notification unit 105 receives a notification request from the life extension control unit 110, it sounds a buzzer (which may also be called a security alarm) 105a for 30 seconds. The notification unit 105 also sends an email to the driver's smartphone 105b, for example, every 10 minutes, a total of three times. This allows people around the vehicle 100 and the driver to be notified that an abandoned vehicle has occurred.

[0025] The air conditioner operating unit 106 operates the air conditioner based on a control signal from the life extension control unit 110. At this time, the air conditioner operating unit 106 operates the air conditioner based on the following control signal. <1> ~ <4> The following operation is performed. <1> Input SOC (State Of Charge) information and determine whether the SOC is 90% or higher. <2> If the SOC is below 90%, the engine will be started if the vehicle is equipped with an internal combustion engine, and charging will begin if the vehicle is an electric vehicle (including BEVs (Battery Electric Vehicles), HEVs (Hybrid Electric Vehicles), PHEVs / PHVs (Plug-in Hybrid Electric Vehicles / Plug-in Hybrid Vehicles), and FCEVs / FCVs (Fuel Cell Electric Vehicles / Fuel Cell Vehicles)). <3> When a request for air conditioning operation is received from the life extension control unit 111, first the vent opening control is performed (because the effect of air conditioning is reduced if the vent is artificially closed), and then the air conditioning and air blowing are operated to reach the target temperature. <4> When a heating operation request is received from the life extension control unit 110, the vent opening control is first performed (because the heating effect is reduced if the vent is artificially closed), and then the heating and air blowing are operated to reach the target temperature.

[0026] The window opening operation unit 107 opens the windows of the vehicle 100 based on a control signal from the life extension control unit 110. For example, when the window opening operation unit 107 receives a window opening request from the life extension control unit 110, it opens the windows of all seats by 5 cm. In this way, by opening the windows to an extent that can mitigate the rise in temperature inside the vehicle without fully opening them, it is possible to suppress the rise in temperature inside the vehicle while suppressing a decrease in security against vehicle break-ins, etc.

[0027] The door lock / door open operation unit 108 unlocks the doors of the vehicle 100 or opens the doors based on a control signal from the life extension control unit 110. Specifically, when the door lock / door open operation unit 108 receives a door unlocking request from the life extension control unit 110, it unlocks the doors of all seats. In addition, in the case of a bus, when the door lock / door open operation unit 108 receives a door unlocking request from the life extension control unit 110, it opens the front and / or middle doors. This makes it easier for people who have been left behind to escape from the vehicle and for people nearby to rescue the people who have been left behind.

[0028] The rescue agency reporting unit 109 notifies a rescue agency such as a fire department that the vehicle has been abandoned and provides information about the location by reporting the location to the rescue agency via, for example, a telephone line or an internet line, based on a control signal from the life extension control unit 110. Here, the location information notified to the rescue agency by the rescue agency reporting unit 109 is, for example, map information (map information) of the vehicle 100 where the abandonment has occurred, latitude and longitude information (GPS information) of the vehicle 100, etc.

[0029] Next, a description will be given of the operation of the vehicle 100 of this embodiment. Fig. 2 is a flowchart showing the flow of life extension control of the vehicle 100 of this embodiment.

[0030] When the life extension control process is started, first in step S11, the life extension control unit 110 determines whether or not an abandonment has occurred. Specifically, when the vehicle state determination unit 101 determines that the vehicle is parked, the vehicle interior detection unit 102 obtains a detection result that there is a person inside the vehicle, and the driver detection unit 103 obtains a detection result that there is no person in the driver's seat, the life extension control unit 110 determines that an abandonment has occurred and proceeds to step S12 (step S11; YES).

[0031] In step S12, life extension control of stage 1 is performed. In step S12, the life extension control unit 110 controls the notification unit 105 to notify the driver that the vehicle has been abandoned by sounding the buzzer 105a of the vehicle 100 or by sending an email to the driver's smartphone 105b. Note that the buzzer 105a may be sounded first, and if the abandonment situation is not resolved, the driver may then be notified by their smartphone.

[0032] In step S13, the life extension control unit 110 determines whether the abandonment has continued for a predetermined time, and if it determines that the abandonment has continued, the process proceeds to step S14 (step S13; YES), and if it determines that the abandonment has not continued, the process returns to step S11 (step S13; NO). Note that the predetermined time here may be, for example, a time set in advance by the user, or may be changed depending on the determination result by the vehicle interior comfort determination unit 104. For example, the higher the temperature inside the vehicle, the more light entering the vehicle, or the louder the baby's crying, the shorter the predetermined time should be.

[0033] In step S14, the life extension control of stage 2 is performed. In step S14, the life extension control unit 110 controls the air conditioning operation unit 106 to control cooling or heating so that the temperature inside the vehicle is comfortable. At this time, the air conditioning operation unit 106 starts the engine or charges the battery according to the remaining battery charge (SOC) in order to perform cooling or heating well.

[0034] In step S15, the life extension control unit 110 determines whether the device has been left for a predetermined time. If it determines that the device has been left, the process proceeds to step S16 (step S15; YES), and if it determines that the device has not been left, the process returns to step S11 (step S15; NO). Note that the predetermined time may be, for example, a time set in advance by the user, or may be changed depending on the remaining amount of energy required to operate the air conditioner. For example, the smaller the remaining amount of energy required to operate the air conditioner, the shorter the predetermined time should be.

[0035] In step S16, stage 3 life extension control is performed. In step S16, the life extension control unit 110 controls the window opening unit 107 and the door lock / door opening unit 108 to open the windows, unlock the doors, and / or open the doors. This allows outside air to be taken into the vehicle even when the air conditioner is stopped. As a result, the rise in the temperature inside the vehicle can be suppressed. This also makes it easier for the person left behind to escape from the vehicle on their own, or for people around the vehicle 100 to rescue the person left behind.

[0036] In step S17, life extension control of stage 4 is performed. In step S17, the life extension control unit 110 notifies a rescue organization (ambulance, fire department, or police) to request rescue via the rescue organization notification unit 109 or the like. In this way, by notifying the rescue organization after notifying the driver and improving the comfort inside the vehicle with the air conditioner, frequent dispatches of rescue organizations can be reduced.

[0037] The process of step S17 may be performed simultaneously with step S16, or may be performed before step S16 and after step S15. In this way, the time when rescue services arrive at vehicle 100 can be accelerated, and the period of reduced security caused by performing step S16 can be shortened.

[0038] Vehicle 100 of this embodiment has the following configuration.

[0039] (1) One aspect of the vehicle 100 disclosed herein has an abandonment detection unit (vehicle state determination unit 101, interior detection unit 102, driver detection unit 103) that detects whether a person has been abandoned inside the vehicle 100, and a life extension control unit 110 that, when the abandonment detection unit (vehicle state determination unit 101, interior detection unit 102, driver detection unit 103) detects abandonment, gradually activates multiple life extension related units of the vehicle 100 (notification unit 105, air conditioner operation unit 106, window opening operation unit 107, door lock / door opening operation unit 108 and / or rescue agency notification unit 109) according to the elapsed time of abandonment.

[0040] This makes it possible to realize a vehicle 100 that can rescue infants, children, and the like left behind inside the vehicle more accurately and safely than conventional vehicles.

[0041] (2) In one aspect of the vehicle 100 of the present disclosure, the life-extension related units (notification unit 105, air conditioner operation unit 106, window opening operation unit 107, door lock / door opening operation unit 108 and / or rescue agency notification unit 109) include the air conditioner operation unit 106 and window and / or door opening operation units (window opening operation unit 107 and / or door lock / door opening operation unit 108), and the life-extension control unit 110 opens the window and / or door using the opening operation unit (window opening operation unit 107 and / or door lock / door opening operation unit 108) after a predetermined time has elapsed since the air conditioner was turned on by the air conditioner operation unit 106.

[0042] This allows the air conditioner to keep the interior of the vehicle comfortable, and even if the air conditioner stops working, the windows and doors will remain open, so life-saving operation can be maintained.

[0043] (3) In one aspect of the vehicle 100 of the present disclosure, the life-saving related units (notification unit 105, air conditioner operation unit 106, window opening operation unit 107, door lock / door opening operation unit 108 and / or rescue agency notifying unit 109) include a first notification unit 105 that notifies the surroundings of the vehicle 100 and / or the driver of the vehicle 100 that the vehicle has been left behind, and a second notification unit (rescue agency notifying unit) that notifies a rescue agency that the vehicle has been left behind, and the second notification unit (rescue agency notifying unit) notifies the rescue agency that the vehicle has been left behind, and the second notification unit (rescue agency notifying unit) notifies the rescue agency after the notification by the first notification unit 105.

[0044] This reduces the need for frequent dispatches of rescue organizations.

[0045] (4) In one aspect of the vehicle 100 of the present disclosure, the life-extension related units (notification unit 105, air conditioner operation unit 106, window opening operation unit 107, door lock / door opening operation unit 108 and / or rescue agency notifying unit 109) include the air conditioner operation unit 106, window and / or door opening operation units (window opening operation unit 107 and / or door lock / door opening operation unit 108), a first notification unit 105 that notifies people around the vehicle 100 and / or the driver of the vehicle 100 that the vehicle has been left behind, and a second notification unit (rescue agency notifying unit) that notifies a rescue agency that the vehicle has been left behind, and the life-extension control unit 110 sequentially performs the following in this order: notification by the first notification unit 105, turning on the air conditioner by the air conditioner operation unit 106, opening operation of the opening operation unit (window opening operation unit 107 and / or door lock / door opening operation unit 108), and notification by the second notification unit (rescue agency notifying unit).

[0046] This makes it possible to perform life-extension control in an appropriate order while minimizing assistance from unrelated people and minimizing deterioration of security.

[0047] (5) One aspect of the vehicle 100 disclosed herein further includes an interior comfort determination unit 104 that determines the comfort level inside the vehicle 100, and when the interior comfort determination unit 104 determines that a life-extension operation is necessary, the life-extension control unit 110 causes the life-extension-related units (notification unit 105, air conditioner operation unit 106, window opening operation unit 107, door lock / door opening operation unit 108, and / or rescue agency notification unit 109) to perform a life-extension operation.

[0048] This allows the life-extending operation to be performed only when the comfort inside the vehicle deteriorates, thereby preventing unnecessary life-extending operation.

[0049] The above-described embodiments are merely examples of specific embodiments of the present invention, and the technical scope of the present invention should not be construed as being limited by these embodiments. In other words, the present invention can be embodied in various forms without departing from the gist or main characteristics thereof.

[0050] In the above embodiment, the case where the parking state is determined by the vehicle state determination unit 101 has been described, but the determination process by the vehicle state determination unit 101 may be omitted. In other words, it may be determined that the vehicle has been abandoned if there is no driver and there is a person in the vehicle. [Industrial Applicability]
