Description
Technical Field
The invention relates to the technical field of vehicle safety, in particular to an in-vehicle safety technology of a vehicle powered by a combustion engine, and particularly provides a camera-based anti-suffocation method for people in the vehicle and a computer readable medium.
Background
Generally, even if a vehicle completely closes a window or a sunroof, an in-vehicle space is not completely closed. A small amount of air exchange can exist between the environment in the vehicle and the outside, and people who have a rest in the vehicle generally do not have the risk of suffocation. However, in the case of a combustion engine vehicle, heating or cooling of an on-board air conditioner is powered based on the operation of the combustion engine. Many people can not find a suitable place to rest due to hot or cold outdoor weather, and choose to start the cold air or hot air of the vehicle-mounted air conditioner to rest in the vehicle under the condition of parking, at the moment, weak air exchange in the vehicle is not enough to fully exchange air in the vehicle with outside air, and the engine can be in an idle running state for a long time by starting the heating or refrigerating function of the vehicle-mounted air conditioner during parking, so that a large amount of carbon monoxide and carbon dioxide can be generated. When the concentration of carbon monoxide and carbon dioxide in the vehicle is too high, people who rest in the vehicle can die due to suffocation.
The existing anti-suffocation technology for the passengers in the vehicle is mainly based on a set of safety systems which are additionally provided, such as a heat sensor, an air sensor, a personnel state sensor, a temperature sensor, an oxygen sensor, a carbon dioxide sensor and the like, and are independently arranged. The main problems of the method are as follows:
1. the vehicle state cannot be recognized effectively, and thus accurate functional service cannot be provided. The additional vehicle state sensor and the like are not based on the existing devices or mature vehicle-mounted equipment of the vehicle, so that the acquired and acquired data are possibly not accurate enough, the state of the vehicle can not be effectively identified, the vehicle state is misjudged, and the anti-suffocation strategy is invalid or the accurate function service effect can not be achieved.
2. Existing on-board systems are not reused, resulting in excessive costs. Independently setting up the anti-asphyxia device and implementing the anti-asphyxia strategy would place more additional devices in the vehicle, obviously the vehicle owner would incur additional expenses and costs for this.

Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, is intended to be illustrative, and not restrictive, and any other similar items may be considered within the scope of the present invention.
Referring to fig. 1, the present invention illustratively provides a camera-based in-vehicle anti-asphyxia system, comprising: the camera is arranged in the vehicle and is positioned at the joint of the A column and the roof of the vehicle, or the joint of the B column and the roof of the vehicle, or the joint of the A column and the B column of the vehicle and the roof of the vehicle; the vehicle body stabilizing system or the wheel sensor is used for monitoring whether the vehicle is parked or whether the vehicle speed is zero or not and sending a monitoring result signal to the vehicle body controller; the advanced driving auxiliary system or the fatigue early warning system is used for monitoring whether personnel in the vehicle are in a rest state or not and sending a monitoring result signal to the vehicle body controller; the vehicle body controller is used for controlling a vehicle body operation mode, preferably controlling the opening or closing of a vehicle window through a vehicle-mounted bus; when the vehicle is parked or the vehicle speed is zero, a vehicle body stabilizing system or a wheel sensor sends a signal to the vehicle body controller in real time through the vehicle-mounted bus so that the vehicle body controller knows that the vehicle is in a parking state or the vehicle speed is zero, when the situation that personnel in the vehicle is in a rest state is monitored, a high-grade driving auxiliary system or a fatigue early warning system sends a signal to the vehicle body controller in real time through the vehicle-mounted bus so that the vehicle body controller knows that the personnel is in a closed eye or lying down state and starts to calculate the duration time of the personnel in the closed eye or lying down state, and when the duration time of the vehicle body controller receiving the condition that the personnel is in the closed eye or lying down state from the high-grade driving auxiliary system or the fatigue early warning system exceeds a threshold value time, and at this time the vehicle body controller receives a signal that the engine is in a running state and a signal that the vehicle is in a parking state (or the vehicle speed is zero) from the engine controller and the vehicle body stabilization system (or the wheel sensor) at the same time, the vehicle body controller controls the vehicle to change from one operation mode to another operation mode. Preferably, the vehicle body controller controls the window to change from the first state to the second state. Preferably, the vehicle body controller controls the window to change from the closed state to the open state. Preferably, the vehicle body controller controls the window to change from the incompletely opened state to the preset opened state.
In addition, fig. 2 shows an example of the mountable position of the in-vehicle camera. The camera is arranged in the vehicle and is positioned at the joint of the A column and the roof of the vehicle, or the joint of the B column and the roof, or the joint of the A column and the B column of the vehicle and the roof.
Referring to fig. 3, there is provided an in-vehicle based anti-asphyxia method 300 according to a preferred embodiment of the present invention, the method 300 including the following steps.
In step 302, the first signal, the second signal, and the third signal are transmitted to the vehicle body controller in real time according to the processing result of the in-vehicle recognition device. Specifically, after a processing result is obtained from an in-vehicle recognition device, a signal (first signal) that the vehicle is in a parking state (or the vehicle speed is zero) is transmitted to the vehicle body controller in real time; sending a signal (a second signal) that the vehicle-mounted air conditioner is in an opening state to the vehicle body controller in real time; and continuously sending a signal (third signal) that the person in the automobile is in a rest state (an eye-closing state or a lying state) to the automobile body controller in real time.
In step 304, the body controller continuously receives the first signal, the second signal, and the third signal, and calculates an accumulated time of continuously receiving the third signal, and changes the vehicle from the first body operation mode to the second body operation mode by the body controller when the accumulated time reaches or exceeds a threshold time. Specifically, when a signal (first signal) that the vehicle is in a parking state (or the vehicle speed is zero state), a signal (second signal) that the vehicle-mounted air conditioner is in an on state, and a signal (third signal) that the vehicle-mounted person is in a rest state (eye-closed state or lying state) are continuously received, an accumulated time during which the signal (third signal) that the vehicle-mounted person is in the rest state or lying state is continuously received is calculated, and when the accumulated time reaches or exceeds a threshold time, a change is made from the first body operation mode (window or sunroof close mode) to the second body operation mode (window or sunroof open mode).
Preferably, the threshold time may be a preset time length, and the preset time length is 10-20 minutes.
Preferably, the window or skylight opening mode comprises a mode that four windows simultaneously adjust a window opening gap to be 10cm and/or open a skylight and tilt tail.
Referring to fig. 4, there is also provided a camera-based in-vehicle anti-asphyxia method 400 according to a preferred embodiment of the present invention, wherein the camera is mounted in the vehicle at a location where an a-pillar meets the roof of the vehicle, or a B-pillar meets the roof of the vehicle, or both the a-pillar and the B-pillar meet the roof of the vehicle, the method 400 comprising the following steps.
In step 402, whether the person in the vehicle is in a rest state or a lying state is judged according to the identification image of the camera, and when the judgment result is yes, a signal that the person in the vehicle is in the rest state or the lying state is continuously sent to the vehicle body controller in real time.
In step 404, after receiving the signal for determining that the person in the vehicle is in the rest state or the lying state, the vehicle body controller determines whether the window is in the completely closed state according to the detection result of the window position sensor.
In step 406, when the vehicle body controller determines that the window is in a completely closed state, the vehicle body controller determines whether the vehicle is in a parking state or a vehicle speed is zero according to a vehicle speed sensor.
In step 408, when the vehicle body controller determines that the vehicle is in the parking state or the vehicle speed is zero, whether the vehicle-mounted air conditioner of the vehicle is in the on state is determined according to the state signal of the vehicle-mounted air conditioner.
In step 410, when the vehicle body controller determines that the vehicle-mounted air conditioner of the vehicle is in an open state, the accumulated time of continuously receiving a signal that the person in the vehicle is in a rest state or a lying state is calculated, and when the accumulated time reaches or exceeds a threshold time, the vehicle window is controlled to be opened to a preset state.
Preferably, the cameras are 4 cameras respectively installed at the junction of the a-pillar and the B-pillar of the vehicle and the roof of the vehicle.
Preferably, the threshold time may be a preset time length, and the preset time length is 10-20 minutes.
Preferably, the preset state of the vehicle window comprises that the four vehicle windows simultaneously adjust the vehicle window opening gap to be 10cm, and open the skylight tail-bending mode, or simultaneously open the vehicle window gap to be 10cm and open the skylight tail-bending mode.
It should be understood that the above method is only a preferred embodiment, and the order of the steps may be interchanged or recombined to obtain a new embodiment, or the steps may be performed independently and out of order.
Further, "judging whether the window is in the completely closed state" may be replaced with "judging whether the window is in an unnormal open state", and the unnormal open state may be a state between the completely closed state and a preset open state. It should be understood that the "non-standard opening state" means that the window is not completely closed, but the opening gap is too small, so that the amount of gas exchange between the inside and the outside of the vehicle is too small to prevent the choking of the inside of the vehicle. Such an "unnormal open state" may be, for example, a window opening by a gap of 0.1 mm. In addition, the "window" may be a "sunroof" or a "door" as long as the window or the door is detected by a vehicle body controller or a sensor and can cause gas exchange between the inside of the vehicle and the outside.
Further, the determination of the parking state is for a vehicle with an electronic handbrake or with a body stabilization system. For the vehicle still using the mechanical hand brake at present, it is only necessary to judge whether the vehicle speed is zero through a wheel sensor or other sensors of the vehicle itself. Although the vehicle speed is zero, the vehicle can not be uniquely determined to be in the parking state, for safety and robustness of the system and the method, when the existing vehicle-mounted equipment of the vehicle cannot obtain a parking state signal or cannot directly and automatically detect whether the vehicle is in the parking state, the technical scheme defined by the invention can be implemented on most of the existing vehicles by adopting the approximation that the vehicle speed is zero.
Further, "determining whether or not the vehicle-mounted air conditioner of the vehicle is in an on state" means determining whether or not the vehicle-mounted air conditioner uses the combustion engine of the vehicle itself to provide power to cool or warm the vehicle, based on the state signal of the vehicle-mounted air conditioner. Further, "determining whether the on-vehicle air conditioner of the vehicle is in the on state" may be replaced with "determining whether the on-vehicle air conditioner of the vehicle is in the failure state". That is, in consideration of the robustness of the system or the method, when the air conditioner is in a failure state, it is not possible to confirm whether the vehicle-mounted air conditioner is still operating, and there is a risk that exhaust gas generated when the combustion engine is idling may enter the vehicle, that is, suffocation of people in the vehicle may occur.
Further, it is possible to omit the determination as to whether or not the in-vehicle air conditioner is in the operating state. Although, the passengers in the vehicle generally do not have to keep the engine idling and turn on the air conditioner to cool or heat, but rest in the vehicle. This situation needs to be avoided, but is not the case of primary concern for the present invention, nor is it a common situation in life. In life, when people rest in the vehicle without turning on the air conditioner, the engine is turned off.
Further, whether the person in the vehicle is in a rest state or a lying state is judged, and generally, the judgment is based on the existing advanced driving assistance system or fatigue early warning system. The camera of the system is used for identifying the facial expressions and the limb actions of the people in the vehicle, and whether the people in the vehicle are in a rest state or not is identified through image processing. In addition, the 'at rest state' belongs to a preset state, and some definitions of the states of the personnel in the advanced driving assistance system or the fatigue early warning system can be borrowed, and some preset states can be added in a targeted manner. For example, if it is detected that the person in the vehicle is in a closed-eye state, or that the person in the vehicle is in a side-lying or supine state; the vehicle interior person is considered to be in a rest state.
Further, the accumulated time of the signal that the person is in the rest state or lying state may be calculated by the processor of the vehicle body controller based on the written software code program, and the threshold time may be a preset value or values. For example, the time for keeping the eyes closed for 10 minutes or more, or the time for keeping the eyes closed for 20 minutes or more, that is, the time for keeping the eyes closed for 20 minutes or more, is 10 minutes. Therefore, the preferable time may be 3 minutes to 30 minutes, and may be 10 to 20 minutes.
Further, the preset state in which the window is opened is opposite to the preset state in which the window is not fully opened. The preset state that the door window was opened promptly can be the degree of opening of compound car internal environment gas exchange, but can not lead to taking away the interior article of car outside the car at will because open too greatly, promptly the property is stolen, or open too greatly and can lead to the interior air conditioner refrigeration of car or heating effect to reduce and even become invalid. Preferably, the window opens with a gap of 10 cm. Preferably, the window has an opening gap of 1cm to 20 cm. Preferably, for a typical car, with four windows controllable to open and close, four windows are opened simultaneously for a 10cm gap. Preferably, for a vehicle having a sunroof, the sunroof is opened. Preferably, the skylight aperture is opened by 10 cm. Preferably, a "tail-tilt" mode or a rear-tilt mode of the sunroof is enabled or a first-gear sunroof is enabled or a sunroof rear gap is opened or a sunroof rear opening mode is enabled. Preferably, the skylight tail-up mode is opened and the window gap is opened by 10cm at the same time. In addition, the window opening gap in the present disclosure may refer to an opening gap of a lift window used in a current vehicle, and the opening window gap of 10cm refers to a gap of 10cm height which occurs when the window is lowered by 10cm from a completely closed state by lifting the window. Further, the preferred mode of window or sunroof opening is one of: the four windows simultaneously adjust the window opening gap to be 10cm, open the tail-tilting mode of the skylight (namely, open the first-gear skylight, open the skylight rear gap or open the skylight rear gap), or simultaneously open the window gap to be 10cm and open the skylight rear gap. In summary, window opening is a window opening manner that can be understood by those skilled in the art.
