Description

Technical Field

[0001] The utility model relates to the field of vehicle monitoring and alarm, in particular to an anti-false-alarm live object detection and alarm system and a vehicle after locking the vehicle. Background Technique

[0002] After the vehicle is locked, since the interior is in a closed state, the temperature inside the vehicle will continue to rise, even far higher than the temperature outside the vehicle. Especially in summer, if a pet or a child is left in the vehicle, it will affect the safety of the child or the pet, and even cause death.

[0003] With the development of vehicle technology, the detection and reminder technology for living things such as children or pets left in the vehicle has gradually been applied to the vehicle interior. For example, a system for warning of a living thing left in the vehicle with the patent application number 201810011465.5, which includes a detection unit, a control unit and an execution unit. The detection unit includes a vehicle flameout detection unit and a life detection unit. The life detection unit analyzes whether there is a crying sound of a living thing in the vehicle by collecting the sound information inside the vehicle, using audio recognition and analyzing the sound information other than the sound intensity. And / or the vehicle flameout detection unit determines whether the vehicle has flamed out by any one or a combination of multiple methods such as detecting whether there is electricity at the charging port, or measuring whether the acceleration of the vehicle by an acceleration sensor is lower than a set value, or through GPS positioning.

[0004] The above patent can detect the crying sound of children in the vehicle through an audio signal after the vehicle has flamed out, and accordingly perform forgetting detection and alarm.

[0005] In the existing technology, such as the identification system for children left in the vehicle in the above patent, the detection and alarm are carried out after the vehicle is turned off and locked. However, an important user requirement is ignored, that is, the user does not forget the children or pets in the back row, but just needs to leave for a few minutes or even one or two minutes. At this time, it is necessary to lock the vehicle to ensure the safety of the children and the property in the vehicle. These few minutes of leaving will not actually pose a safety risk to the children or pets in the vehicle, but the above-mentioned solutions in the existing technology will still keep alarming in this case. At this time, the alarm can be considered as a false alarm that does not meet the actual needs of the user, resulting in insufficient user experience of detecting and alarming living things left in the vehicle and unable to meet the actual needs of the user. Content of the Utility Model

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following briefly describes the content expressed in each drawing of the present invention specification and the marks in the drawings:

[0016] Figure 1 It is a schematic diagram of a conventional living being recognition and alarm system in the prior art;

[0017] Figure 2 It is a schematic diagram of the living being recognition and alarm system of the present utility model. Specific embodiments

[0018] Next, with reference to the accompanying drawings, through the description of the optimal embodiments, the specific embodiments of the present invention will be further described in detail.

[0019] As Figure 1 shown, it is a schematic diagram of living being detection and alarm in the prior art; after the vehicle is locked, the status data inside the vehicle is collected by the camera or microphone MIC inside the vehicle and sent to the control host. The control host generally uses the in-vehicle multimedia host for multiplexing. By identifying and analyzing the video data and voice data, it is determined whether there are living beings such as children or pets inside the locked vehicle. If so, an alarm is sent to the user through the in-vehicle 4G network. The component for the user to receive the alarm is the owner's mobile phone APP. In this way, an alarm can be sent in time after locking the vehicle to avoid safety accidents. However, although this method can effectively avoid omitting children or pets inside the vehicle and improve safety. However, some real situations are not considered. For example, the driver only needs to leave for three to five minutes temporarily, and locking the pet inside the vehicle is to ensure the safety of the pet and the property inside the vehicle. Even in winter or in some places where the weather temperature is not high, locking the car door is actually safer and the living beings such as pets inside the vehicle will not be suffocated or have safety hazards. Therefore, according to this alarm method of the prior art, the user's need for such a short-term departure will be ignored, and it cannot be met and the continuous alarm affects the user experience.

[0020] As Figure 2 shown, it is an anti-false alarm living being detection and alarm system after locking the vehicle provided by this solution, including a living being detection and alarm module, a control host, an engine-off detection module, a display screen, a voice reminder module, a confirmation button, and a timer; the living being detection and alarm module is connected to the control host; the engine-off detection module is connected to the input end of the control host; the output end of the control host is connected to the display screen and the voice reminder module, and is used to control the display screen and the voice reminder module to send a reminder signal after the engine is turned off; the confirmation button is connected to the input end of the control host and is used to collect the signal of the user triggering the confirmation button; the timer is connected to the control host, and the control host controls the timer to perform a delay drive to make the living being detection and alarm module work according to the trigger signal of the confirmation button. The engine-off detection module is used to detect the engine-off state of the vehicle. After the vehicle is turned off, the control host detects the living beings in the back row based on the living being detection and alarm module and sends a reminder of living beings in the back row to the user through the display screen and the voice reminder module; at the same time, it detects the trigger signal of the confirmation button and controls the alarm to send an alarm signal based on the delay after the confirmation button is triggered.

[0021] The working principle is introduced as follows:

[0022] The living being detection and alarm module includes a living being detection unit and an alarm unit. The living being detection unit includes any one of an in-vehicle camera, an infrared detector, and / or a sound detector, which is used to detect living beings in the vehicle, and its output end is connected to the control host; the alarm unit includes a vehicle-end alarm module and a remote alarm module. The vehicle-end alarm module includes an in-vehicle horn, which emits an alarm by driving the horn; the remote alarm module is Figure 2 as shown, which is the user's mobile phone app, and sends an alarm reminder to the vehicle owner's mobile phone app through the 4G network.

[0023] The flameout detection module is used to detect the driving state of the vehicle, and is used to detect the vehicle flameout or the high-voltage-off signal, which indicates that the vehicle has stopped and the driver has a need to leave; its output end is connected to the control host; after obtaining the vehicle flameout signal, the control host drives the living being detection unit to work, and the living being detection unit detects the living beings in the back row of the vehicle. If no living beings are detected, it ends, and the control host goes to sleep and prohibits sending an alarm. If living beings are detected, the control host drives the display screen and the voice reminder module to send a signal of living beings in the vehicle to remind the driver to pay attention and avoid omission. Here, the display screen can be implemented by an in-vehicle multimedia display screen, and the voice reminder module can also reuse the in-vehicle voice system, such as the voice in the multimedia system or the intelligent voice assistant, so as to send a voice reminder to the user, such as "Passengers in the back row are detected, please don't forget the passengers in the back row" and other similar voice reminders.

[0024] While driving the display screen to send a voice reminder, it is detected whether the confirmation button is activated. If the driver does not trigger the confirmation button, it means that the driver has indeed forgotten the passengers in the back row. At this time, after detecting that the vehicle door is locked, a reminder signal of forgetting living beings is continuously sent through the vehicle-end alarm module and the remote alarm module; if the driver knows that there are living beings in the back row and judges that he locks the car briefly and goes out, at this time the driver can trigger the confirmation button. After the confirmation button is triggered, the control host does not immediately alarm, but drives the timer to delay. After the delay reaches the set time, an alarm reminder is sent through the remote alarm module, that is, an alarm signal is sent to the vehicle owner's APP to remind the vehicle owner. The purpose of doing this is that when the driver has a need to go out briefly, the driver is allowed to delay the alarm through the confirmation button. However, when the delay time is reached and the vehicle door is not unlocked and the living being detection signal still exists, it is judged that the driver has forgotten, and at this time the remote alarm module repeatedly sends a reminder to the vehicle owner through the vehicle owner's APP; if the vehicle owner returns within the delay time, the control host can detect the state of the vehicle door unlocking, etc., and then this system automatically goes to sleep and waits for the next start. This can reduce the defect of repeated alarms when the driver goes out briefly, meet the needs of users, improve the user experience, and when the delay ends, continue to execute the alarm, improve the safety of living beings in the vehicle, and achieve the purpose of timely reminder.

[0025] In a preferred embodiment, the delay time in the delay device is generally several minutes or even more than ten minutes, which can be set according to the conditions of different locations. Therefore, a delay setting module is provided. The delay setting module is connected to the control host and is used to manually input the delay alarm time of the delay device. In this way, the user can set and adjust the delay time of the delay device for delay alarm according to actual needs. Of course, in order to improve safety, a maximum delay time threshold is preset in the control host to prohibit the delay time set by the user from exceeding the delay threshold, thus ensuring safety. The safety threshold time can be calibrated and set by the vehicle factory.

[0026] In another preferred solution of this embodiment, the control host is connected to the vehicle high-voltage module or the ignition module and is used to drive the vehicle to go high-voltage or start ignition after the delay ends; the output end of the control host is connected to the vehicle window or the air conditioner and is used to adjust and control the state of the vehicle window and / or the air conditioner. The output end of the control host is connected to the door lock unit and is used to lock the vehicle door after driving the vehicle to go high-voltage or start ignition. Since the starting methods of electric vehicles and fuel vehicles are different, the starting of an electric vehicle is to go high-voltage while the starting of a fuel vehicle is to ignite. Therefore, the control host is connected to the high-voltage module of the electric vehicle or the ignition module of the fuel vehicle. After the delay ends, if the door unlock is not detected, the driver signal is not detected, or the PEPS key approach signal is not detected, it can be judged that the driver has forgotten the living thing in the vehicle at this time. Therefore, automatic control of the vehicle is required at this time to improve the safety of the living thing in the vehicle. In this regard, the control host drives the vehicle to start and power on, and controls the air conditioner to start or opens the vehicle window, so that the potential safety hazard caused by risks such as sultriness to the living thing in the vehicle can be reduced; further, in order to avoid the safety impact caused by the door unlock after the vehicle starts, a control signal is actively output to vehicle-mounted controllers such as the BCM at this time to control the door to be locked, thus ensuring the locking safety of the vehicle. This control method can ensure the safety and reliability of the living thing in the vehicle. As long as the driver returns and unlocks the vehicle and powers on or ignites again through the key, the control host controls the living thing detection and alarm system to go to sleep at this time, completing the functions and purposes of this detection and alarm.

[0027] In this embodiment, a vehicle is also provided. The vehicle includes an anti-false-alarm live-thing detection and alarm system after locking the vehicle in the above embodiment. Since the vehicle includes all the features in the above embodiment, it has all its characteristics and technical advantages. This solution can meet the needs of users to briefly lock the vehicle and go out with a living thing in the vehicle and alarm again when the driver does not come back beyond the set time, improving the user experience of the live-thing detection system.

[0028] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
