FIG. 3 is a flow diagram illustrating another hazard protection method that may be performed by the hazard protection system described above, and in particular, by a control system therein, according to an exemplary embodiment. As shown in fig. 3, the method includes:
s301, acquiring passenger information in the vehicle.
In particular embodiments, the control system may include or be in signal communication with an ECU in the vehicle that sends a key-off signal to the control system when the ECU detects and determines that the vehicle is turned off. In some embodiments, the control system may also acquire the vehicle's key-off signal directly from sensor elements throughout the vehicle. The misfire signal may include at least one of vehicle speed and engine speed. For example, when the ECU detects that the vehicle speed of the vehicle is zero and the rotational speed of the transmitter is also zero, it can be considered that the vehicle has stalled.
When the control system confirms that the vehicle is turned off, the control system may acquire occupant information of the interior of the vehicle from the in-vehicle sensing system in response to acquiring the key-off signal. In some embodiments, after the control system confirms that the vehicle is turned off, the control system may send a start signal to the in-vehicle sensing system to start the in-vehicle sensing system, control an image acquisition device (hereinafter, referred to as a first image acquisition device) in the in-vehicle sensing system to acquire image information of the interior of the vehicle, and control a radar device (hereinafter, referred to as a first radar device) in the in-vehicle sensing system to emit electromagnetic waves and detect an echo signal. Subsequently, the first image capturing device may transmit the detected image information of the vehicle interior to the control system, and the first radar device may also transmit the echo signal detected by the first radar device to the control system.
In some embodiments, the in-vehicle sensing system may be in operation at all times and sense occupant information within the vehicle at fixed intervals. After the control system receives the key-off signal, the in-vehicle sensing system may send the current latest occupant information to the control system.
When the control system receives the image information of the interior of the vehicle, the control system can identify the object type existing in the image information according to the image information and confirm whether the object type belongs to a target type, wherein the target type at least comprises any one of children and pets. An object belonging to the target type is determined as an occupant inside the vehicle. For example, the control system may extract feature information and a contour of the object from the image information, and determine the object type through big data contrast based on the feature information and the contour. Further, the control system may also determine the number of occupants and the occupant position based on the image information.
The first radar device provided by the embodiment of the application can be a millimeter wave radar which can send electromagnetic waves to the interior of a vehicle and realize identification of a living body and the state of the living body based on echo Doppler frequency analysis. Micro-motion of the life body target can generate micro-Doppler frequency modulation on a radar echo signal, and micro-motion parameters are estimated by extracting micro-Doppler characteristics contained in the radar echo, so that the micro-motion state of the life body target can be inverted. Therefore, the control system can realize breathing detection, position detection and the like of the living body in the vehicle based on the echo signal transmitted by the first radar device.
In the embodiment of the present application, the occupant information may include the number of occupants, and may further include at least one of position information and status information. By combining the image information provided by the first image acquisition device and the echo signal provided by the first radar device, the accuracy and precision of the passenger information acquired by the control system are improved.
In an embodiment of the present application, the image information and the echo signals are analyzed by the control system to determine occupant information within the vehicle interior. In other embodiments, the image information and the echo signal may be analyzed by the in-vehicle sensing system, and then the analyzed occupant information in the vehicle may be directly transmitted to the control system.
S302, obtaining driver information in the vehicle.
In a specific embodiment, the first image capturing device and the first radar device may be preset to detect only a set region inside the vehicle, which may be, for example, the rear row of the vehicle, so that the number of occupants in the rear row may be directly determined based on the image information and the echo signal.
When the number of passengers is not zero, the control system can further start the image acquisition device and the radar device at the driving position to acquire the passenger information in the vehicle. The energy consumption of the sensing system in the vehicle can be saved by opening the image acquisition device and the radar device in the vehicle in different areas.
In other embodiments, the first image capture device and the first radar device may be configured to detect the entire vehicle interior, such that the control system or the in-vehicle sensing system may obtain both occupant information and driver information. Further, the control system or the in-vehicle sensing system may determine whether or not a living body is present at the driver's position based on the detected position information of the object to determine whether or not the driver is in the vehicle interior, and determine whether or not a living body (i.e., an occupant) is present in the rear row (predetermined area) of the vehicle and the number of living bodies, thereby determining the number of living bodies in the predetermined area as the number of occupants.
That is, the acquiring of the occupant information in the vehicle interior in the above step may include: acquiring image information of the interior of the vehicle detected by an image acquisition device; acquiring an echo signal detected by a radar device; determining the number of living bodies in the set area based on the image information and the echo signal; the number of occupants is determined according to the number of living bodies.
Therefore, the sequence of step 301 and step 302 is not limited in this embodiment of the application. For example, step 301 and step 302 may be performed simultaneously, and after acquiring the occupant information and the driver information, it is determined whether the occupant information is zero.
And S303, when the number of the passengers is not zero, determining whether the driver is in the vehicle or not based on the driver information.
In particular embodiments, the driver information may include driver location information. The control system or in-vehicle sensing system may determine whether the driver is inside the vehicle based on the driver position information.
When the number of occupants is not zero and the driver is inside the vehicle, step S304 is performed to send the first prompt information to the driver.
The driver may leave the vehicle interior without timely obtaining the first prompt information and forget the rear passenger in the vehicle interior, in which case the second prompt information may be sent to the driver. That is, when the number of occupants is not zero and the driver leaves the vehicle interior, step S305 is performed to transmit the second prompt information to the driver. The prompting intensity of the second prompting message can be larger than that of the first prompting message.
In some embodiments, when it is determined that the number of occupants is zero, the in-vehicle sensing system may be turned off and the steps of obtaining driver information or determining whether the driver is inside the vehicle are not performed.
And S304, sending first prompt information to the driver.
In a particular embodiment, the control system may activate the in-vehicle reminder device to send the first reminder message to the driver, since the driver has not left the vehicle interior. For example, the in-vehicle prompting device may be a HUD (Head Up Display), a car audio, or the like, and correspondingly, the first prompting information may be at least one of text information, image information, or sound information.
And S305, sending second prompt information to the driver.
When the driver leaves the vehicle, the control system can start the remote prompting device to send second prompting information to the driver. Illustratively, the remote prompting device can be a wireless communication device such as bluetooth or WIFI. The communication device such as the driver's mobile phone may be in signal connection with the wireless communication device in the vehicle so that the wireless communication device in the vehicle may send the second prompt message to the communication device of the user. The second prompt message may be at least one of a text message, an image message or a voice message.
In some embodiments of the present application, in order to avoid that the driver does not notice the second prompt message sent by the remote prompt device after leaving the vehicle, the passenger is in danger in the closed vehicle environment. The control system can also count the time length for the driver to leave the vehicle, or the time length or the time number for sending the second prompt message, or the temperature in the vehicle is detected through the temperature sensor, and when the time length, the time number or the temperature reach a set threshold value, the vehicle is controlled to execute the protection operation. For example, the safeguard operation may be at least one of opening a window of the vehicle or opening an outer cycle of the vehicle.
In the embodiment of the application, the dangerous condition that may exist in the vehicle after the driver leaves the vehicle can be protected through the in-vehicle sensing system, and in some embodiments, the dangerous condition that may exist outside the vehicle can also be protected through the out-of-vehicle sensing system.
As shown in fig. 4, the method may further include:
s401, obtaining driver information in the vehicle.
In a specific embodiment, this step may be implemented by an operation similar to step S302 described above. Also, in a scenario of safeguarding against a dangerous situation that may exist outside the vehicle, the control system may acquire the driver information in response to acquiring the key-off signal. In other words, in the embodiment of the present application, the control system may acquire the driver information and the occupant information at the same time in response to acquiring the key-off signal.
For example, after confirming that the vehicle is turned off, the control system may send a start signal to the in-vehicle sensing system to start the in-vehicle sensing system, control a first image acquisition device in the in-vehicle sensing system to acquire image information of the inside of the vehicle, and control a first radar device in the in-vehicle sensing system to emit electromagnetic waves and detect an echo signal. Subsequently, the first image capturing device may transmit the detected image information of the vehicle interior to the control system, and the first radar device may also transmit the echo signal detected by the first radar device to the control system.
The control system may detect the number and position of the living bodies inside the vehicle from the received image information and the echo signal, and may use the living body information at the position corresponding to the driver as the driver information.
S402, whether the driver is in the vehicle is determined based on the driver information.
In a specific embodiment, the driver information may include driver position information, which may be implemented by an operation similar to step S303 described above. The control system or the in-vehicle sensing system may determine whether the driver is inside the vehicle based on the driver position information. Illustratively, the control system receives the image information and the echo signal to detect the number and the position of the living bodies inside the vehicle, and determines whether a living body is present at the position of the driver based on the position information of the detected living bodies to determine whether the driver is inside the vehicle.
S403, acquiring environment information outside the vehicle;
in the embodiment, when the control system confirms that the vehicle is turned off and the driver does not leave the vehicle interior, it returns to step S401 described above to repeatedly detect the driver information in the vehicle interior.
After the control system confirms that the vehicle is shut down and the driver leaves the interior of the vehicle, the control system can send a starting signal to the external sensing system so as to start the external sensing system, control an image acquisition device (hereinafter referred to as a second image acquisition device) in the external sensing system to acquire image information outside the vehicle, and simultaneously control a radar device (hereinafter referred to as a second radar device) in the external sensing system to emit electromagnetic waves and detect echo signals. Subsequently, the second image capturing device may transmit the detected image information of the vehicle interior to the control system, and the second radar device may also transmit its detected echo signal to the control system.
In some embodiments, the off-board sensing system may be in operation at all times and sense environmental information external to the vehicle at fixed intervals. After the control system receives the flameout signal, the vehicle exterior sensing system can send the current latest environmental information to the control system.
The environmental information may include obstacle information. Specifically, the control system may determine obstacle information present in the environment outside the vehicle, which may include at least one of an obstacle type, an obstacle distance, a moving speed of the obstacle, and the like, based on the image information and the echo information. In addition, the environment information may further include traffic information, which may include at least one of lane line information, signal light information, speed limit information, and the like.
In some embodiments, the hazard protection system may further include a high-precision mapping and positioning system, through which the control system may obtain mapping and positioning information to more accurately obtain environmental information external to the vehicle.
In some embodiments, the vehicle exterior sensing system may employ a look-around camera, and a plurality of radar devices may be arranged outside the vehicle, and the plurality of radar devices may employ radars of different wavelengths, so as to ensure accuracy of the collected environmental information.
For example, a first image capturing device may be disposed at a front end of the vehicle interior, and a first radar device may be disposed at a middle top end of the vehicle interior. The front end of the outside of the vehicle can be respectively provided with a second image acquisition device and a second radar device, the rear end of the outside of the vehicle can be provided with a second image acquisition device, each side edge of the outside of the vehicle can be respectively provided with at least one second image acquisition device, and each side corner is provided with one second radar device. In other embodiments, a second image capture device may be disposed on the roof of the vehicle and a second radar device may be disposed on the rear exterior of the vehicle.
S404, determining the danger level of the current position of the vehicle based on the environment information.
In a specific embodiment, the control system may pre-store a corresponding relationship between the environmental event and the risk level, and the control system may determine the environmental event corresponding to the current position of the vehicle according to the environmental information, and determine the risk level of the current position of the vehicle according to the corresponding relationship between the environmental event and the risk level.
For example, the environmental information may further include vehicle body information, and the control system may acquire the vehicle body information outside the vehicle based on the second image pickup device, and determine whether there is a danger of a pedestrian scratching or illegal entry based on the vehicle body information, and may determine such danger as a low danger level. The risk of collision is determined based on the obstacle information and the risk of collision is determined as a higher risk level.
Further, the control may determine the danger level of the collision further based on the type of the obstacle and the moving speed of the obstacle. For example, when the obstacle is large in size, such as a type of an obstacle having a large size like a truck or a bus, and the moving speed of such an obstacle is fast, the control system may determine the risk level of the current position as a high level. When the obstacle is a pedestrian, the risk level of the current position may be determined as a lower level. A higher risk level may be determined when a geological disaster is determined to be present at the current location of the vehicle based on the high-precision mapping and positioning system.
That is, the control system may couple the type of the obstacle, the distance of the obstacle, the moving speed of the obstacle, the information around the vehicle body, the map, and the positioning information to determine the risk level of the current position of the vehicle, specifically, determine an environmental event corresponding to the current position of the vehicle by coupling the plurality of types of information, and determine the risk level of the current position of the vehicle according to the correspondence between the environmental event and the risk level, so that the accuracy of determining the risk level may be improved.
When the danger level reaches the set value, step S405 described below is executed to control the vehicle to move away from the current position for danger avoidance. In other embodiments, other hedge operations may be performed for lower hazard levels. For example, the vehicle body surrounding information of the vehicle is sent to the driver, and the vehicle body surrounding information can be presented in a video form, so that the driver can conveniently determine the cause of the danger according to the vehicle body surrounding information afterwards, and the monitoring function is achieved.
And S405, controlling the vehicle to drive away from the current position.
When the control system determines that automatic departure of the vehicle needs to be performed, a surrounding safe location, such as a surrounding parking lot or the like, may be selected based on the high-precision map and positioning system and a path plan provided. The control system may automatically drive away from the current location and move to a safe location based on the planned path. In some embodiments, the safe location is a parkable location marked in a map. The control system may detect the safe locations within the predetermined area based on the high-precision map and the positioning system and select the safe location with the highest priority according to the priority of the safe locations. In particular, the priority of the safety location may depend on at least one of a distance between the safety location and the current location, a driving difficulty of a planned path corresponding to the safety location, and a size of the safety location. The closer the distance between the safety position and the current position, the lower the driving difficulty, and the larger the scale, the higher the priority of the safety position.
And S406, updating the environment information outside the vehicle.
After the vehicle moves to the safe position, the external sensing system of the vehicle repeatedly detects the environmental information outside the vehicle so as to update the environmental information outside the vehicle.
And S407, sending the updated environment information to the driver.
The vehicle exterior sensing system sends the updated environment information to the control system, and the control system can send the updated environment information to the driver through the remote prompting device, so that the driver can conveniently determine the updated vehicle position.
Accordingly, embodiments of the present application provide a hazard protection system that includes a control system and an in-vehicle sensing system. Wherein,
