[0023] Figure 3 It is a structural schematic diagram of the electronic device provided by the present invention. DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to facilitate understanding of the vehicle safety monitoring method, device and vehicle provided by the present invention, the application background is first introduced. For the driver, the car is generally a temporary resting place. When the driver is resting in the car, personal and property safety becomes the most important issue. One of the possible hazardous scenarios is that when the driver stops to rest, there are illegal intruders outside the car who want to carry out illegal intrusion activities. However, it is difficult for the driver to detect abnormal activities outside the car in time when resting. Even if he notices it, he cannot effectively detect the situation outside the car, which makes it difficult to ensure his own personal and property safety.

[0026] At present, although some vehicles are equipped with radar systems or electronic rearview mirrors to display the outside environment, the main function of the radar system or electronic rearview mirror is to display blind spots to assist driving. When the vehicle is powered off, it enters sleep mode and cannot monitor the situation outside the vehicle when the driver is resting.

[0027] Therefore, how to enable the driver to promptly and effectively detect abnormal conditions outside the vehicle when resting and ensure the safety of his or her life and property is an important issue that needs to be solved urgently.

[0028] In view of the above problems, the present invention provides a vehicle safety monitoring method, device and vehicle, which can enable the driver to detect abnormal conditions outside the vehicle in a timely and effective manner to ensure the safety of his or her life and property.

[0029] Combine the following Figure 1-Figure 3 The vehicle safety monitoring method, device and vehicle of the present invention are described.

[0030] Figure 1 is a flow chart of a vehicle safety monitoring method provided by an embodiment of the present invention. The method can be applied to a vehicle controller, such as an ECU (Electronic Control Unit, a vehicle computer), etc. Figure 1 As shown, the method comprises the following steps: Step 10: Get the vehicle's power-on status.

[0031] Step 11: When the power-on state is determined to be power-off, enter the linkage alarm mode.

[0032] Step 12: In linkage alarm mode, obtain the driver's location information.

[0033] Step 13: When it is determined that the driver has stayed in the vehicle for more than a set time, the environment information outside the vehicle is obtained.

[0034] Step 14: When it is determined that there is an abnormality in the environmental information outside the vehicle, an alarm is triggered and the display screen 202 of the electronic rearview mirror 200 is activated to display the image outside the vehicle.

[0035] The power-on status of a vehicle refers to the startup or activation status of the vehicle's electrical system. Generally speaking, when the vehicle is powered on, it often means that the vehicle is about to start, that is, the driver is about to enter the driving state, and when the vehicle is powered off, it often means that the vehicle is turned off or in a turned-off state, that is, the driver is about to enter the parking and resting state. Therefore, by judging the power-on status of the vehicle, it is possible to roughly judge whether the driver is about to stop and rest.

[0036] Specifically, the vehicle's power-on status can be determined by the KL15 signal. In the automotive electrical system, KL15 usually refers to a specific power signal, which represents the vehicle's main power status. In some vehicles, the KL15 signal can be controlled by the position of the car key. When the car key is turned from the "off" position to the "power-on" position, the KL15 signal will be activated to power the vehicle's electronic system. In addition, the KL15 signal can also be activated by a button, that is, by pressing the start / stop button to activate the KL15 signal, the vehicle enters the power-on state. Therefore, by detecting the KL15 signal, it can be determined whether the vehicle is in the power-on state.

[0037] When it is determined that the vehicle's power-on status is off, the linkage alarm mode is entered. In the linkage alarm mode, the driver's location information is first obtained to determine whether the driver is resting in the car. If the driver stays in the car for more than the set time, it means that the driver is resting in the car. If the driver stays in the car for less than the set time, it means that the driver is not resting in the car.

[0038] Specifically, the location information of the driver can be determined by the location information of the car key, and the location of the car key is specifically determined by the following steps: Get the distance between the car key and the vehicle.

[0039] When it is determined that the distance between the car key and the vehicle is within a set threshold, it is determined that the car key is located inside the vehicle. When it is determined that the distance between the car key and the vehicle exceeds the set threshold, it is determined that the car key is located outside the vehicle.

[0040] For the driver, the car key is usually carried with him, so the position of the car key can usually represent the driver's position, and then determine whether the driver is in the car and how long the driver stays in the car.

[0041] More specifically, the location information detection of the car key can rely on RFID (radio frequency identification). By embedding an RFID tag in the car key, when the car key is inside the car, the RFID reader inside the car will receive the signal from the tag, thereby confirming that the key is inside the car. When the car key is a certain distance away from the vehicle, the RFID reader cannot receive the signal from the tag, and it is determined that the car key is outside the car. In addition, the location information detection of the car key can also rely on wireless communication. By enabling the wireless module built into the car key to establish communication with the vehicle antenna, the approximate distance between the car key and the vehicle is estimated through the signal strength indication (Received Signal Strength Indication, RSSI) or signal delay analysis, and then it is inferred whether the car key is inside the car.

[0042] It is understandable that the position detection of the car key includes but is not limited to the methods listed above, and other methods may also be applicable.

[0043] By detecting the position of the car key, it is determined whether the driver is in the car and how long the driver stays in the car. When the driver's stay time in the car exceeds the set value, for example, when the driver stays in the car for more than five minutes, ten minutes or other predetermined time periods, it indicates that the driver is resting in the car. At this time, the environmental information outside the car is obtained. If the environmental information outside the car is abnormal, an alarm is triggered to prompt the driver that there is abnormal activity outside the car, and at the same time, the display screen 202 of the electronic rearview mirror 200 is activated to display the picture outside the car, so that the driver can detect the situation outside the car in a timely and effective manner, judge whether the abnormal activities outside the car will affect his own personal and property safety, and take corresponding countermeasures.

[0044] Environmental information outside the vehicle can be collected by various types of sensors equipped on the vehicle, such as radar probes 300 arranged around the vehicle and vibration sensors 301 on the vehicle.

[0045] Among them, the radar probe 300 can monitor whether there are objects approaching around the vehicle. Specifically, the radar probe 300 includes a transmitter and a receiver. The transmitter emits high-frequency electromagnetic waves, which will propagate to the surrounding environment. When the electromagnetic waves encounter an object, they will be reflected back to the radar sensor. The receiver receives these reflected waves and converts them into electrical signals. After filtering, amplification and demodulation, information is extracted. The time delay of the reflected wave can be converted into the distance of the object, and the frequency change of the reflected wave can be converted into the speed of the object. By comparing the echo signals at different time points, the existence, position and movement of the target are detected, and the movement trajectory of multiple objects is tracked using a multi-target tracking algorithm. By monitoring the distance between the target and the vehicle, the trajectory and speed of the target moving toward the vehicle, etc., it is determined whether the target has abnormal activity.

[0046] The vibration sensor 301 can collect vibration information of the vehicle body. When the vehicle body vibrates, the frequency, intensity and duration of the vibration are recorded. If the intensity or duration of the vibration exceeds a set threshold, it is determined to be abnormal vibration. Specifically, the vibration sensor 301 can be installed on the fuel tank of the vehicle.

[0047] The radar system and the vibration sensor 301 cooperate to monitor the environment outside the vehicle. When there is an abnormality in the external environment information, an alarm prompt is triggered. The alarm prompt can be presented in the form of sound, such as a buzzer, so that the driver can promptly detect abnormal activities outside the vehicle. When necessary, the alarm prompt can also be presented in the form of sound and light to improve the alarm effect.

[0048] At the same time as the alarm prompts, the display screen 202 of the electronic rearview mirror 200 is activated to display the image outside the vehicle. The electronic rearview mirror 200 usually includes a camera installed on the outside of the vehicle and a display screen 202 installed inside the vehicle, which is used to replace the traditional optical rearview mirror. When the alarm prompts, although the driver can be aware of abnormal activities outside the vehicle, he still needs to accurately detect the situation outside the vehicle to determine whether there is a false alarm, so as to take corresponding response strategies according to the accurate situation.

[0049] In one embodiment of the present invention, the above method may further include the following steps: In response to the shutdown command, the alarm prompt and the display screen 202 of the electronic rearview mirror 200 are turned off. If the driver finds a false alarm through the display screen 202, or determines that the abnormal activity outside the car does not pose a threat, the alarm prompt and the display screen 202 of the electronic rearview mirror 200 can be actively turned off to avoid interrupting the rest.

[0050] Specifically, the shutdown command can be triggered by a function switch 400 set in the vehicle, and the shutdown command is transmitted to the controller in a wired manner. The shutdown command can also be triggered by a mobile phone, a remote controller, etc., and the shutdown command is transmitted to the controller in a wireless manner. When the driver finds a false alarm or determines that there is no threat outside the vehicle, the shutdown command can be triggered by the function switch 400, a mobile phone, or a remote controller, etc., to turn off the alarm prompt and the display screen 202 of the electronic rearview mirror 200.

[0051] In another embodiment of the present invention, the above method may further include the following steps: In response to the shutdown command, the linkage alarm mode is exited, and at least some functional modules of the vehicle are controlled to enter a dormant state. When the driver determines that the surrounding environment is safe enough, in order to avoid affecting rest, the linkage alarm mode can be exited by the shutdown command, and at least some functional modules of the vehicle can be controlled to enter a dormant state. Specifically, when the vehicle is in the dormant mode, its electronic rearview mirror 200, radar and other sensors are in a dormant state, so as to reduce the energy consumption of the vehicle.

[0052] It is understandable that the shutdown command can be triggered after the vehicle is powered off. At this time, although the vehicle is in a powered-off state, it will not enter the linkage alarm mode. The shutdown command can also be triggered at any stage of the above steps to exit the linkage alarm mode at any time.

[0053] In one embodiment of the present invention, the above method may further include the following steps: In response to the start command, and when it is determined that the vehicle is powered off, the linkage alarm mode is entered to facilitate the driver to take safety protection when resting. Specifically, the start command can be triggered by a function switch 400 set in the vehicle, and the start command is transmitted to the controller in a wired manner, or the start command can be triggered by a mobile phone, a remote controller or other device, and the start command is transmitted to the controller in a wireless manner.

[0054] By adopting the above-mentioned technical solution, if the driver finds a false alarm through the display screen 202, or determines that the abnormal activity outside the vehicle does not pose a threat, the driver can trigger a shutdown command through the function switch 400 or a mobile phone, remote control, etc. to exit the linkage alarm mode. At this time, the alarm prompt and the display screen 202 of the electronic rearview mirror 200 are turned off, and at least some functional modules of the vehicle enter a dormant state. If the driver determines that the surrounding environment is safe enough, the linkage alarm mode can be kept exited in order to avoid affecting rest. If the linkage alarm mode needs to be restarted, the start command is triggered through the function switch 400 or a mobile phone, remote control, etc., and the linkage alarm mode is restarted when it is determined that the vehicle is powered off to facilitate the driver to perform safety protection while resting.

[0055] In one embodiment of the present invention, the above method may further include the following steps: When it is determined that the alarm prompt duration exceeds the preset duration, the alarm prompt and the display screen 202 of the electronic rearview mirror 200 are turned off.

[0056] Sometimes the driver discovers a false alarm through the display screen 202, or determines that the abnormal activities outside the vehicle do not pose a threat, but it is inconvenient for the driver to get up to trigger the shutdown command. The alarm prompt duration exceeds the preset duration, for example, after one or two minutes, the alarm prompt and the display screen 202 of the electronic rearview mirror 200 are automatically turned off, which is conducive to improving the flexibility of control.

[0057] In one embodiment of the present invention, the above method may further include the following steps: When the vehicle is powered on, the linkage alarm mode is exited. When the vehicle is powered on, it indicates that the driver is driving or about to drive, and the linkage alarm mode is exited. In the driving state, although the electronic rearview mirror 200, radar and other sensors of the vehicle are still in working state, the linkage alarm is no longer performed.

[0058] In one embodiment of the present invention, the above method may further include the following steps: When it is determined that the driver has not stayed in the vehicle for more than a set time, the linkage alarm mode is exited and at least part of the functional modules of the vehicle are controlled to enter a dormant state.

[0059] Specifically, when the driver stays in the car for less than the set time, it means that the driver is not resting in the car. At this time, the linkage alarm mode is exited and the vehicle's electronic rearview mirror 200, radar and other sensors enter a dormant state to reduce the vehicle's energy consumption.

[0060] It is to be understood that, without mutual contradiction, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification.

[0061] By using the vehicle safety monitoring method, device and vehicle provided by the embodiments of the present invention, the driver enters the linkage alarm mode when resting.

When the environmental information outside the vehicle is abnormal, an alarm prompt is triggered, so that the driver can promptly notice the abnormal activities outside the vehicle, and at the same time activate the display screen of the electronic rearview mirror to display the outside picture. The driver can promptly and effectively detect the situation outside the vehicle and judge whether the abnormal activities outside the vehicle pose a threat, so that the driver can take corresponding countermeasures in time to achieve the purpose of protecting property safety and personal safety.
