[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Application Overview

[0024] The existing technology for detecting whether there is someone in the car has unstable detection results. For example, when detecting whether there is someone in the car through the in-car camera, the following situation may occur: at the beginning, when someone is detected through face recognition, the vehicle automatically increases the screen brightness; afterwards, the face of the person in the car may be blocked by an obstruction (such as a seat), causing the detection result to become no one, and the vehicle automatically lowers the screen brightness, which affects the use of the screen by the people in the car. It can be seen that the instability of the detection results of whether there is someone in the car will affect the control of the vehicle functions.

[0025] In order to solve the above problems, an embodiment of the present application provides a vehicle control technology. Based on the stability principle that the presence or absence of anyone in the vehicle should not change suddenly when all doors are closed, the target function of the vehicle is always controlled based on the initial detection result before any door is detected to be opened. This can overcome the problem of target function control being affected by the instability of the presence or absence detection result.

[0026] Exemplary Methods

[0027] The embodiment of the present application provides a vehicle control method, which is applied to a vehicle, and specifically can be a control device in the vehicle, such as an onboard terminal, a vehicle machine module, a vehicle controller, a domain controller, etc. The method can be executed when the vehicle network is in an awake state.

[0028] The method is described in detail below through some embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0029] like Figure 1 As shown, the method may include steps 101 to 103, as described below:

[0030] Step 101: When it is detected that all vehicle doors are in a closed state, detect whether there is anyone in the vehicle and obtain an initial detection result.

[0031] In the embodiment of the present application, when the control device detects that all vehicle doors are in a closed state, it can control the corresponding detection device to detect whether there is anyone in the vehicle and obtain an initial detection result.

[0032] The initial detection result is a relatively reliable detection result, which is used to indicate whether there is someone in the car or no one in the car. That is, when someone is detected in the car, an initial detection result indicating that there is someone in the car is generated; when no one is detected, an initial detection result indicating that there is no one in the car is generated.

[0033] Specifically, the control device may start detecting whether there is anyone in the vehicle when detecting that a vehicle door is in an open state and all vehicle doors are in a closed state.

[0034] The switch state of the door can be detected by a door sensor arranged on the door, and the door sensor sends the sensed information to the control device, which analyzes the information to obtain the detection result of the switch state of the door.

[0035] Optionally, the door sensor may be a magnetic sensor, which determines the open / closed state of the door by detecting the change in the magnetic field near the door. When the door is closed, the magnetic element approaches the magnetic sensor, changing the output signal of the magnetic sensor, and the control device may determine whether the door is closed based on the output signal of the magnetic sensor.

[0036] Optionally, the door sensor may also be a capacitive sensor, which determines the door state by detecting the capacitance change between the door and the vehicle body. When the door is closed, the capacitance change is measured by the capacitive sensor, and the control device may determine whether the door is closed based on the capacitance value measured by the capacitive sensor.

[0037] Optionally, the door sensor can also be a photoelectric sensor, which detects the door state by using the light between the transmitter and the receiver. When the door is closed, the light emitted by the transmitter is blocked by the door, causing the light intensity received by the receiver to change, and the control device can determine whether the door is closed according to the light intensity received by the receiver.

[0038] In addition, the door sensor can also be a Hall sensor, which determines the open and closed state of the door by detecting the change of the magnet at the door position. It is understandable that the type of door sensor is not limited to this, and any sensor that can detect the open and closed state of the door can be used, and the embodiment of the present application does not specifically limit this. In addition, the specific position of the door sensor on the door can be set according to actual needs, and the embodiment of the present application does not specifically limit this.

[0039] Optionally, in the embodiment of the present application, whether there is someone in the car can be detected based on the seat occupancy sensor. The main principle is to sense the pressure change on the seat by installing a pressure sensitive chip inside the seat. These chips are evenly distributed on the force-bearing surface of the seat. When someone sits on the seat, the weight of the human body will cause the seat to generate corresponding pressure. The pressure sensitive chip can detect the pressure change and transmit this information to the control device. The control device determines whether there is someone on the seat based on such information, and thus determines whether there is someone in the car.

[0040] In addition, the in-car camera can also be used to detect whether there is someone in the car. The main principle can be to capture the in-car environment image through the in-car camera, separate the foreground (such as the person in the car) and the background (such as the in-car environment) from the image through image segmentation technology, and identify and classify the target in the foreground image through the target detection algorithm to determine whether it has human characteristics, and then determine whether there is someone in the car. Optionally, the detection of whether there is anyone in the car can be achieved through the intelligent visual monitoring system (In-cabin monitoring System, IMS) of the vehicle cockpit. The intelligent visual monitoring system may include: a driver monitoring system (Driver Monitoring System, DMS) and an occupancy monitoring system (Occupancy Monitoring System, OMS). The driver monitoring system can monitor the driver's fatigue state, dangerous driving behavior, etc., while the passenger monitoring system can monitor the passenger's age, state, mood, etc. To achieve the above-mentioned function, the driver monitoring system includes a camera for collecting the driver's image, and the passenger monitoring system includes a camera for collecting the passenger's image. Therefore, the detection of whether there is anyone in the car can be achieved through the intelligent visual monitoring system (In-cabin monitoring System, IMS).

[0041] In addition, as the penetration rate of voice recognition technology in the vehicle field gradually increases, voice recognition technology can also be used to detect whether there is someone in the car. Specifically, the sound can be collected through the microphone in the car, and based on the sound intensity, frequency and other sound characteristics, it can be judged whether there is someone in the car.

[0042] Of course, if the car is equipped with a millimeter-wave radar, it can also detect whether there is someone in the car through the millimeter-wave radar. The main principle is: the millimeter-wave signal will be reflected when it encounters a human body or other obstacles in the car. By analyzing the frequency, amplitude, phase and other parameters of the reflected signal, the human body's breathing, heartbeat and other vital signs signals can be identified, thereby determining whether there is someone in the car.

[0043] The embodiment of the present application may use at least one detection means according to actual needs to realize the detection of whether there is anyone in the vehicle in the embodiment of the present application, and the specific detection means used is not limited to the above-mentioned detection means.

[0044] Preferably, since a seat occupancy sensor is generally provided on a vehicle seat, and the detection means has a high accuracy rate in detecting the presence of a person, and will not make a reverse misjudgment, that is, will not mistakenly detect a person as being present when no person is present, therefore, the embodiment of the present application can preferably detect whether there is someone in the vehicle based on the seat occupancy sensor.

[0045] Step 102: Based on the initial detection result, control the target function of the vehicle.

[0046] The target function mentioned here refers to a function in which the control strategies are different when there is someone in the car and when there is no one in the car, that is, the control strategy of the target function when there is someone in the car is different from the control strategy when there is no one in the car.

[0047] In the embodiment of the present application, it is possible to pre-set which functions the target functions specifically include, and how these functions are specifically controlled when there is someone in the car and when there is no one in the car.

[0048] For example, the target function may include a screen brightness control function. When the initial detection result indicates that there is someone in the car, the corresponding control strategy is to increase the screen brightness to ensure that the people in the car can clearly see the screen information; when the initial detection result indicates that there is no one in the car, the corresponding control strategy is to lower the screen brightness or turn off the screen to save energy and extend the service life of the screen.

[0049] In addition to the screen brightness control function, the target function can also include the vehicle system volume adjustment function. When the initial detection result indicates that there is someone in the car, the volume of the vehicle system can be automatically adjusted to provide a better hearing experience for the occupants; when the initial detection result indicates that there is no one in the car, the volume of the vehicle system can be increased to enhance the alarm sound and improve the safety warning effect.

[0050] The target function may also include the activation and disabling of audio devices (such as speakers, microphones, etc.) inside and outside the vehicle. When the initial detection result indicates that there is someone in the vehicle, the vehicle can automatically activate the audio device inside the vehicle to facilitate voice interaction or navigation instructions for the person inside the vehicle, and disable the audio device outside the vehicle so that the person outside the vehicle cannot control the vehicle through voice commands; when there is no one in the vehicle, the vehicle can automatically disable the audio device inside the vehicle to prevent the noise inside the vehicle from interfering with the surrounding environment, and activate the audio device outside the vehicle so that the owner can control the vehicle from outside the vehicle.

[0051] In addition to the above functions, the target function may also include: seat position adjustment function, air conditioning temperature adjustment function, window height adjustment function, etc. Such functions can be differentially controlled depending on whether there is someone in the car or no one in the car.

[0052] Of course, in the embodiment of the present application, it is also possible to dynamically determine which target functions to control. For example, different entertainment functions can be enabled for people of different ages and genders in the car. For example, for young people, the music playback function can be enabled; for middle-aged people, the radio function can be enabled, etc.

[0053] In addition, in the embodiment of the present application, the control parameters corresponding to the target function can be pre-set. For example, for the screen brightness adjustment function, the brightness when there is someone in the car can be set to 60% of the maximum brightness, and the brightness when there is no one in the car can be set to 0 or 10% of the maximum brightness. It is understandable that the control parameters corresponding to the target function can also be dynamically adjustable. For example, when there is someone in the car, the screen brightness can be dynamically adjusted according to the brightness of the interior environment to provide a better screen usage experience. For another example, when the detection method of whether there is someone in the car includes voice recognition, image recognition and other methods, in addition to detecting whether there is someone in the car, it is also possible to specifically determine the identity information of the person in the car when someone is detected in the car, and different identity information can correspond to different control parameters. Continuing with the screen brightness adjustment function as an example, for example, for driver A, based on his historical use habits of the screen, it is determined that driver A likes a higher screen brightness, then the screen brightness can be set to 65%; for driver B, based on his historical use habits of the screen, it is determined that driver B likes a lower screen brightness, then the screen brightness can be set to 45%.

[0054] Step 103: Before any door is detected to be opened, if the detection result of whether there is someone in the vehicle changes relative to the initial detection result, the target function continues to be controlled based on the initial detection result.

[0055] The vehicle door is the regular way for people to enter and exit the vehicle. When the vehicle doors are in the closed state, the state of someone in the vehicle or no one in the vehicle should not change suddenly. In other words, when the vehicle doors are in the closed state, there is either always someone in the vehicle or no one in the vehicle. The embodiment of the present application is based on this stability principle. Before any vehicle door is detected to be opened, even if the detection result of whether there is someone in the vehicle changes relative to the initial detection result, it will be ignored or deemed invalid, and the target function of the vehicle will always be controlled based on the initial detection result.

[0056] For example, the initial detection result indicates that there is someone in the car, and the control device increases the screen brightness as if there is someone in the car. In subsequent detections, the detection result indicates that there is no one in the car, but the door has not been opened, so there should be someone in the car. This means that the jump in the detection result is unreliable and a false detection may have occurred. Therefore, the screen brightness is kept unchanged as if there is someone in the car, rather than lowered as if there is no one in the car.

[0057] This can overcome the problem of the instability of the detection results of whether there is someone in the car affecting the control of the target function, improve the accuracy of the vehicle's intelligent control, better meet the needs of the people in the car, and enhance the vehicle's user experience. In addition, the detection accuracy of the door opening and closing signals is high, which means that the state of the door can be detected more accurately, which helps to further improve the stability of the target function control. And this technical solution can be implemented using existing functions on the vehicle, such as the door opening and closing detection function, the vehicle occupancy detection function, etc., without the need to add hardware equipment, and the implementation cost is low.

[0058] In some optional embodiments, in step 101: after detecting whether there is someone in the vehicle when all vehicle doors are detected to be in a closed state, the vehicle control method may further include:

[0059] Within the first time threshold, if someone is detected in the car at any time, an initial detection result indicating that there is someone in the car is generated; if no one is detected in the car within the first time threshold, the initial detection result indicating that there is no one in the car is generated.

[0060] The first duration threshold mentioned here can be understood as the initial detection duration, which can be set according to actual needs. Specifically, it can be started from the moment when the control device detects that all doors are in a closed state. Assume that the first duration threshold is 2 minutes, and the control device determines the moment when all doors are in a closed state based on the signal sent by each door sensor, and starts timing. Within 2 minutes, as long as someone is detected in the car, an initial detection result indicating that there is someone in the car is generated; within 2 minutes, if no one is detected in the car, an initial detection result indicating that no one is in the car is generated.

[0061] In the embodiment of the present application, in order to obtain relatively accurate, stable and reliable initial detection results, the initial detection time period can be set, and the initial detection result can be obtained based on the detection results within the initial detection time period.

[0062] In some optional embodiments, in step 101: after detecting whether there is someone in the vehicle when all vehicle doors are detected to be in a closed state, the vehicle control method may further include steps A1 and A2, as described below:

[0063] Step A1: When it is detected that any door changes from a closed state to an open state, the detection of whether there is someone in the vehicle is stopped, and the target function is controlled based on the initial detection result.

[0064] In the embodiment of the present application, when the control device detects that all the vehicle doors are in a closed state and then any vehicle door is opened, because the vehicle door is opened, someone may enter the vehicle, and the vehicle may change from being empty to being occupied; or someone may come out of the vehicle, and the vehicle may change from being occupied to being empty. Therefore, at this time, the stable state of whether there is someone in the vehicle has been broken. In addition, the open state of the vehicle doors is generally short-lived, and the state of whether there is someone in the vehicle is also unstable. Therefore, before the vehicle doors are restored to being fully closed, the detection of whether there is someone in the vehicle can be suspended to save energy and detection resources, and the target function can continue to be controlled based on the initial detection results.

[0065] It is understandable that before the vehicle doors are restored to be fully closed, the detection of whether there is someone in the vehicle can continue, and the target function can be controlled based on the new detection results.

[0066] Step A2: When it is detected again that all the doors are in the closed state, re-detect whether there is anyone in the car, obtain a new initial detection result, and control the target function based on the new initial detection result.

[0067] When the control device detects that the car door is closed again after one of the car doors is opened, it can re-detect whether there is someone in the car, obtain a new round of initial detection results, and control the target function based on the new initial detection results. For example, if the initial detection result in step 101 indicates that there is someone in the car, the screen brightness is increased based on the initial detection result; if the initial detection result in step A2 indicates that there is no one in the car, the screen brightness is decreased based on the initial detection result.

[0068] In some optional embodiments, in step 101: after detecting whether there is someone in the vehicle when all vehicle doors are detected to be in a closed state, the vehicle control method may further include:

[0069] When the vehicle is in motion, or all doors are closed for a period greater than or equal to a second time threshold, detection of whether there is someone in the vehicle is stopped before any door is detected to be opened, and the target function is controlled based on the initial detection result.

[0070] When the vehicle is in motion (such as a speed greater than 0 or a certain value), people outside the vehicle generally will not open the door to enter the vehicle, and people inside the vehicle will not open the door to walk out of the vehicle. At this time, the status of people in the vehicle will be relatively stable, that is, there will either always be someone in the vehicle or there will be no one in the vehicle (such as in the case of unmanned automatic driving). Therefore, in this case, in order to save energy and detection resources, the detection of whether there is someone in the vehicle can be stopped before any door is detected to be opened, and the target function can be controlled based on the initial detection result.

[0071] The second time threshold is greater than the first time threshold, and is used to characterize a time period during which the vehicle presence / absence state is stable. When the duration of all doors being in the closed state is greater than or equal to the second time threshold, it indicates that the vehicle presence / absence state is basically stable. In order to save energy and detection resources, the vehicle presence / absence detection may be stopped before any door is detected to be opened, and the target function may be controlled based on the initial detection result.

[0072] In some optional embodiments, the "detecting whether there is someone in the car and obtaining an initial detection result" in step 101 may include steps B1 and B2, as described below:

[0073] Step B1: Detect whether there is someone in the car through various detection methods.

[0074] The embodiment of the present application can detect whether there is someone in the car through various detection means. For example, seat occupancy sensors, image recognition technology, millimeter wave radar technology, etc. can be used to detect whether there is someone in the car to improve the accuracy of the detection result.

[0075] Step B2: When the detection results corresponding to the multiple detection methods are inconsistent, the detection result of the detection method with a higher confidence level is used as the initial detection result.

[0076] In the embodiment of the present application, a confidence level can be set in advance for each detection means, and the confidence level is used to indicate the credibility of the detection means. Generally, the higher the accuracy of the detection result, the higher the confidence level of the corresponding detection means; conversely, the lower the accuracy of the detection result, the lower the confidence level of the corresponding detection means. The confidence levels of different detection means can be obtained based on experiments, and then the confidence levels of the detection means can be calibrated based on the experimental results.

[0077] In the embodiment of the present application, when the detection results corresponding to multiple detection methods are inconsistent, the detection result corresponding to the detection method with the highest confidence can be used as the initial detection result. Assume that the confidence of the millimeter wave radar is 98%, the confidence of the seat occupancy sensor is 95%, and the confidence of the image recognition technology is 90%. If the detection results of whether there is someone in the car obtained by each detection method are inconsistent, the detection result of the millimeter wave radar shall prevail, that is, the detection result of the millimeter wave radar shall be used as the initial detection result.

[0078] In some optional embodiments, the "detecting whether there is someone in the car and obtaining an initial detection result" in the previous step 101 may include steps C1 and C2, as described below:

[0079] Step C1: Detect whether there is someone in the car through various detection methods.

[0080] The embodiment of the present application can detect whether there is someone in the car through various detection means. For example, seat occupancy sensors, image recognition technology, etc. can be used to detect whether there is someone in the car to improve the accuracy of the detection result.

[0081] Step C2: When the detection results corresponding to the multiple detection methods are inconsistent, the detection result indicating that there is someone in the car is used as the initial detection result.

[0082] When the detection results corresponding to multiple detection methods are inconsistent, the goal can be to prioritize the use needs of the occupants in the car, so the detection result indicating that there is someone in the car can be used as the initial detection result to control the target function. For example, if the seat occupancy sensor detects that there is someone in the car, but the image recognition technology does not detect that there is someone in the car, the detection result of the seat occupancy sensor shall prevail, that is, the detection result of the seat occupancy sensor shall be used as the initial detection result.

[0083] In summary, the vehicle control method provided in the embodiment of the present application is based on the stability principle that when the doors are all closed, there should be no jump between the state of people in the vehicle and the state of no one in the vehicle. Before any door is detected to be opened, the target function of the vehicle is always controlled based on the initial detection result. This can overcome the problem of the instability of the detection result of whether there is anyone in the vehicle affecting the control of the target function and improve the vehicle use experience. In addition, the technical solution can be implemented by using existing functions on the vehicle, such as the door opening and closing detection function, the vehicle occupancy detection function, etc., without adding hardware equipment, and the implementation cost is low.
