Example 1

Referring to FIG. 1 , a flowchart of steps of a method for detecting and controlling life leftovers in a vehicle according to an embodiment of the present invention is shown. As shown in FIG. 1 , the control method is applied to a vehicle, and may specifically include the following steps:

S101. When it is detected that the vehicle is turned off and there is no user in the main driving seat, perform biometric detection on the interior space of the vehicle to obtain biometric information in the vehicle;

In this step, the working state of the engine of the vehicle is read from the CAN line of the vehicle, and the engine of the vehicle in this step needs to be in an off state; the method for judging that there is no user at the main driver's seat may be to set a gravity sensor on the main driver's seat , or by collecting the image information of the main driver and judging whether there are human features in the image, in a feasible implementation manner, the opening and closing of the door of the main cockpit can also be obtained through the door module of the vehicle. After the vehicle is turned off, when the door of the main cockpit opens and closes, the user in the main cockpit can be considered to have gotten off the vehicle.

When the engine is in the idle state, even if the user at the main driver gets off the car, the user should only park for a short time and should return to the vehicle as soon as possible, so this method is not applied when the vehicle is in the idle state.

After it is detected that the vehicle is turned off and there is no user at the main driver, biometric detection is performed on the interior space of the vehicle to obtain biometric information in the vehicle, that is, to determine whether there is a living being in the interior space of the vehicle; in this embodiment Among them, the biometric information can include biometric temperature information, biometric sound information, biometric breathing information, and biometric motion information. When detecting biometrics, the corresponding biometric information can be obtained through various types of sensors installed on the vehicle.

S102, analyzing the biometric information to obtain a target organism corresponding to the biometric information;

In this step, the biometric information is obtained and analyzed, and the biometric information can be compared with the preset judgment conditions. If the biometric information meets the judgment conditions, it can be determined that there is life in the vehicle, and the living objects in the vehicle can be determined. The identity judgment has been carried out, and the corresponding target creature has been determined.

S103, when the target creature is a child feature and/or a pet feature, control the vehicle to output an alarm according to the current locked state of the vehicle to remind the user that there are children and/or pets left in the vehicle;

In this step, when the target creature is a child feature and/or a pet feature, according to the current lock state of the vehicle, the lock state of the vehicle can be read from the CAN line of the vehicle, and according to the different lock states of the current vehicle, control The vehicle outputs an alarm warning to remind the user that there are children and/or pets left in the vehicle;

If there are other adults in the target creature in addition to the characteristics of children and/or pets, it is considered that someone can take care of the children and pets, and the user does not need to be alerted.

S104, wherein when the current locked state of the vehicle is an unlocked state, control the vehicle to give a sound warning, and not respond to a user's vehicle locking command within a specified time.

In this step, when the target creature is a child feature and/or a pet feature, if the current locked state of the vehicle is an unlocked state, that is, the user on the main driver has just got off the car and the vehicle has not been locked yet. , at this time, if the user sends a lock command to the vehicle, the sound device set on the vehicle can issue a sound warning, so as to remind the user that there are children and/or pets left in the vehicle; and do not respond to the user's lock command within the specified time. To lock the vehicle, after the calibration time, the vehicle can be locked in response to the user's lock command; the calibration time is set before the vehicle leaves the factory, for example, the calibration time can be 1min.

For example, when the user gets out of the car and has not locked the car, it is detected that there are only children and pets in the vehicle. At this time, the user sends a lock command, and the vehicle starts to sound an alarm to remind the user that there are children and/or pets left in the vehicle. If the user only briefly If you get out of the car to go shopping, he can continue to lock the vehicle after 1 minute, so as to ensure the safety of children and pets.

If the detected target creature has more than child characteristics and/or pet characteristics, or no child characteristics and/or pet characteristics, the user can immediately lock the vehicle.

In a feasible implementation, in step S103, when the target creature is a child feature and/or a pet feature, according to the current locked state of the vehicle, the vehicle is controlled to output an alarm warning to remind the user that there are leftovers in the vehicle. Children and/or pets, also include the following steps:

S105. When the current locked state of the vehicle is the locked state, control the vehicle to send remote prompt information to the user's terminal device.

In this step, if the current locked state of the vehicle is the locked state, that is to say, after the user of the main driver gets off the vehicle and has already locked the vehicle, but there are still children and/or pets left in the vehicle, In order to remind the user not to forget that there are children and/or pets in the vehicle, the vehicle can be controlled to send remote prompt information to the user's terminal device.

After the vehicle is locked, the CO2 concentration inspection sensor can detect the change in the concentration of CO2 inside the vehicle.

The change in CO2 concentration can reflect whether there are living organisms in the vehicle that need to absorb oxygen. In the case of a sealed vehicle, if the concentration of CO2 in the vehicle increases, it is considered that there are living organisms in the vehicle. The concentration of CO2 generally does not change greatly.

2, in step S102, the biological feature information is analyzed to obtain the target creature corresponding to the biological feature information, including the following sub-steps:

S1021. Analyze the biometric information to determine whether there is a living creature in the vehicle;

In this step, when the vehicle is in an unlocked state and the biological temperature information is greater than 30-45 degrees, it is considered that there is a biological creature in the vehicle;

When the vehicle is in a locked state, when the biological temperature information is greater than 30-45 degrees, or when the carbon dioxide concentration information in the vehicle is greater than the carbon dioxide calibration concentration value, or when the biological sound information is greater than the sound intensity calibration value, as long as one of the three conditions is satisfied One, it can be determined that there are creatures in the vehicle.

S1022. If there is a living being, acquire an image inside the vehicle;

In this step, when it is detected that there is a living creature inside the vehicle, an image inside the vehicle is obtained, and an image inside the vehicle can be obtained by setting a camera inside the vehicle.

S1023, extracting human facial features and/or pet facial features from the image inside the vehicle;

In this step, the acquired image inside the vehicle is processed, and human facial features and/or pet facial features are extracted from the image. After the pet facial features are acquired, it can be considered that there is a pet inside the vehicle.

S1024, according to the extracted facial features of the person, perform age recognition of the person;

In this step, the age of the person is identified on the extracted facial features of the person.

S1025, when the age of the character is less than the age calibration value, determine that the biological feature is a child feature.

In this step, if it is recognized that the age of the character is less than the calibration age, it can be considered as a child characteristic, wherein the setting of the calibration age can be changed according to different needs.

Specifically, in step S101, biometric detection is performed on the interior space of the vehicle, including:

When the vehicle is in a locked state, biometric detection is performed on the interior space of the vehicle within a calibrated time.

That is, after the vehicle is locked, biometric detection is performed on the interior space of the vehicle within the calibration time; in one embodiment, if it is detected that children and/or pets are left in the vehicle within the calibration time, the Send remote prompt information to the user's terminal device within a calibrated time interval, such as once every five minutes, until the child and/or pet are removed from the vehicle; When the time arrives, the detection of vital signs is stopped, thereby saving energy.
