[0001] The present disclosure relates to the field of vehicle control, and in particular to a rearview mirror control method and a vehicle. Background Art

[0002] With the rapid development of vehicle technology, vehicles have become an important means of transportation in people's daily lives. When users drive a vehicle, they need to observe the vehicles coming from behind in some scenarios such as turning and changing lanes to avoid traffic accidents.

[0003] Currently, users usually use rearview mirrors to observe the vehicles behind them, but due to the limited field of view of the rearview mirror, there are blind spots, which pose a safety hazard. Summary of the invention

[0004] In view of this, the purpose of the present disclosure is to propose a rearview mirror control method and a vehicle to solve the problem that users currently usually use rearview mirrors to observe vehicles behind, but due to the limited field of view of the rearview mirror, there are blind spots in the field of view, which poses a safety hazard.

[0005] Based on the above purpose, a first aspect of the present disclosure provides a rearview mirror control method, the method comprising:

[0006] Obtaining the vehicle speed of the vehicle, or the following distance between the target rear vehicle and the vehicle, wherein the target rear vehicle is the rear vehicle closest to the vehicle;

[0007] Determine that the vehicle speed or the following distance meets a preset rearview mirror adjustment condition, and adjust the rearview mirror of the vehicle.

[0008] Based on the same inventive concept, the second aspect of the present disclosure provides a rearview mirror control device, comprising:

[0010] The rearview mirror adjustment module is configured to determine whether the vehicle's driving speed or the following distance meets a preset rearview mirror adjustment condition and adjust the rearview mirror of the vehicle.

[0011] Based on the same inventive concept, the third aspect of the present disclosure proposes an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the rearview mirror control method as described above when executing the computer program.

[0019] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0021] With the rapid development of vehicle technology, vehicles have become an important means of transportation in people's daily lives. When users drive a vehicle, they need to observe the vehicles coming from behind in some scenarios such as turning and changing lanes to avoid traffic accidents.

[0022] Currently, users usually use rearview mirrors to observe the vehicles behind them, but due to the limited field of view of the rearview mirror, there are blind spots, which pose a safety hazard.

[0023] Based on the above description, this embodiment proposes a rearview mirror control method, such as Figure 1 As shown, the method includes:

[0024] Step 101, obtaining the vehicle speed of the vehicle, or the following distance between the target rear vehicle and the vehicle, wherein the target rear vehicle is the rear vehicle closest to the vehicle.

[0025] In specific implementation, the vehicle speed of the vehicle is obtained, and the vehicle speed can be obtained by the vehicle sensor. Alternatively, the following distance between the target rear vehicle and the vehicle can also be obtained. There may be multiple vehicles behind the vehicle. For safety reasons, the rear vehicle closest to the vehicle should be considered first. Therefore, in this embodiment, the target vehicle is the rear vehicle closest to the vehicle.

[0026] In this embodiment, the identification of the target rear vehicle and the determination of the following distance can be achieved by relying on the driving perception system of the vehicle. Specifically, a camera, a laser radar, infrared rays, etc. can be used.

[0027] Step 102, determining whether the vehicle speed or the following distance satisfies a preset rearview mirror adjustment condition, and adjusting the rearview mirror of the vehicle.

[0028] In specific implementation, it is determined whether the vehicle speed meets the preset rearview mirror adjustment conditions. If the rearview mirror adjustment conditions are met, it means that the rearview mirror should be adjusted to avoid safety accidents.

[0029] Alternatively, it is determined whether the following vehicle distance satisfies a preset rearview mirror adjustment condition. If the rearview mirror adjustment condition is satisfied, it indicates that the rearview mirror should be adjusted to avoid a safety accident.

[0030] In this embodiment, the rearview mirror adjustment condition corresponding to the vehicle speed is a condition related to the vehicle speed, and the rearview mirror adjustment condition corresponding to the following vehicle distance is a condition related to the distance, and the two are not the same.

[0031] In this embodiment, adjusting the rearview mirror of the vehicle may mean adjusting the driver's side rearview mirror and the passenger side rearview mirror at the same time, or determining the corresponding rearview mirror to be adjusted based on the position of the target rear vehicle relative to the vehicle.

[0032] Specifically, with the traveling direction as the front, if the target rear vehicle is located behind the left side of the vehicle, the rearview mirror to be adjusted is determined to be the driver's side rearview mirror. If the target rear vehicle is located behind the right side of the vehicle, the rearview mirror to be adjusted is determined to be the passenger side rearview mirror.

[0033] Through the above scheme, by obtaining the vehicle speed of the vehicle, or the following distance between the target rear vehicle and the vehicle, since there may be multiple vehicles behind the vehicle, the vehicle mainly considers the rear vehicle closest to itself when driving, so the target rear vehicle is selected as the rear vehicle closest to the vehicle. It is judged whether the vehicle speed or the following distance meets the preset rearview mirror adjustment conditions. At this time, the rearview mirror should be adjusted to eliminate certain blind spots, avoid the problem of safety hazards caused by the fixed field of view of the rearview mirror, and improve driving safety.

[0034] In some embodiments, step 102 specifically includes:

[0035] Step 1021, in response to the following vehicle distance being less than a preset distance threshold, determining that a preset rearview mirror adjustment condition is satisfied;

[0036] Step 1022, determining a target rearview mirror outward angle according to the following vehicle distance, and controlling the rearview mirror of the vehicle to adjust from the current angle to the target rearview mirror outward angle.

[0037] In specific implementation, the following distance between the target rear vehicle and the vehicle is obtained, and the following distance is compared with a preset distance threshold. If the following distance is less than the preset distance threshold, it means that the distance between the target rear vehicle and the vehicle is close, so the driver may want to pay more attention to the position of the target rear vehicle through the rearview mirror, and then adjust the rearview mirror at this time, that is, meet the preset rearview mirror adjustment condition, and the preset rearview mirror adjustment condition is that the following distance is less than the preset distance threshold.

[0038] The database stores the correspondence between the following distance and the rearview mirror folding angle. After the following distance between the target rear vehicle and the vehicle in question is determined, the database is searched based on the following distance to determine the target rearview mirror folding angle corresponding to the following distance. The rearview mirror of the vehicle in question is controlled to adjust from the current angle to the target rearview mirror folding angle so that the target rear vehicle is always in the center of the rearview mirror's field of view when moving forward, so that the user can observe the target rear vehicle through the rearview mirror.

[0039] It is understandable that the current angle may be less than the target rearview mirror eversion angle, may be greater than the target rearview mirror eversion angle, or may be equal to the target rearview mirror eversion angle. If the current angle is less than the target rearview mirror eversion angle, the rearview mirror of the vehicle is controlled to be adjusted from the current angle to the target rearview mirror eversion angle, which is equivalent to controlling the rearview mirror of the vehicle to flip outward to the target rearview mirror eversion angle. If the current angle is greater than the target rearview mirror eversion angle, the rearview mirror of the vehicle is controlled to be adjusted from the current angle to the target rearview mirror eversion angle, which is equivalent to controlling the rearview mirror of the vehicle to flip inward to the target rearview mirror eversion angle.

[0040] In this embodiment, flipping inwards and flipping outwards mean that the height of the rearview mirror remains unchanged and it is only flipped left or right. Specifically, if the driver's side rearview mirror is adjusted, flipping outwards means that the rearview mirror is flipped to the left. If the passenger side rearview mirror is adjusted, flipping outwards means that the rearview mirror is flipped to the right.

[0041] Through the above scheme, by adjusting the target rearview mirror tumbling angle according to the following vehicle distance, since the following vehicle distance changes in real time, the corresponding target rearview mirror tumbling angle also changes, thereby realizing dynamic adjustment of the rearview mirror and making the rearview mirror tumbling angle more accurate.

[0042] In some embodiments, step 1022 specifically includes:

[0043] Step 10221, determining an initial rearview mirror folding angle according to the following vehicle distance, and comparing the initial rearview mirror folding angle with a preset angle threshold;

[0044] Step 10222, in response to the initial rearview mirror eversion angle being greater than or equal to a preset angle threshold, using the preset angle threshold as a target rearview mirror eversion angle; or,

[0045] Step 10223, in response to the initial rearview mirror eversion angle being less than a preset angle threshold, the initial rearview mirror eversion angle is used as a target rearview mirror eversion angle.

[0046] In a specific implementation, the initial rearview mirror folding angle is determined by searching a database according to the following vehicle distance, wherein the database stores a corresponding relationship between the following vehicle distance and the initial rearview mirror folding angle.

[0047] The initial rearview mirror flip angle is compared with a preset angle threshold, wherein the preset angle threshold represents the maximum flip angle allowed for the vehicle rearview mirror while ensuring safe driving. Since the field of view of the vehicle rearview mirror includes not only the vehicle behind the vehicle but also the vehicle itself, the corresponding flip angle of the rearview mirror also has a maximum value.

[0048] If the initial rearview mirror eversion angle is greater than or equal to the preset angle threshold, that is, the rearview mirror eversion angle determined according to the following vehicle distance is greater than the set maximum eversion angle, the preset angle threshold is used as the target rearview mirror eversion angle.

[0049] If the initial rearview mirror eversion angle is less than the preset angle threshold, the initial rearview mirror eversion angle may be used as the target rearview mirror eversion angle.

[0050] Through the above scheme, by setting the maximum outward turning angle of the rearview mirror, it is avoided that the vehicle itself does not exist in the rearview mirror, causing safety hazards and leading to the occurrence of safety accidents.

[0051] In some embodiments, after step 1022, the method further includes:

[0052] Step 10A, determining whether the target rear vehicle has entered the field of vision of the driver of the vehicle;

[0053] Step 10B, in response to determining that the target rear vehicle has entered the field of vision of the driver of the vehicle, determining whether there is a new target rear vehicle, and adjusting the rearview mirror of the vehicle according to the determination result, wherein the new target rear vehicle is a rear vehicle whose following distance with the vehicle is less than a preset distance threshold.

[0054] In specific implementation, when the rearview mirror of the vehicle is controlled to be adjusted from the current angle to the target rearview mirror outward angle, the target rear vehicle is continuously monitored to determine whether the target rear vehicle enters the human eye field of the driver of the vehicle, that is, whether the driver of the vehicle can observe the target rear vehicle through human eyes without the help of a rearview mirror.

[0055] If it is determined that the target rear vehicle enters the field of vision of the driver of this vehicle, the driver of this vehicle can directly observe the target rear vehicle with his eyes without the assistance of the rearview mirror. Therefore, the rearview mirror no longer needs to monitor the position of the target rear vehicle.

[0056] Determine whether there is a new rear vehicle whose following distance to the vehicle is less than a preset distance threshold. If so, take the rear vehicle as a new target rear vehicle, continue to monitor the position of the new target rear vehicle, and further adjust the rearview mirror.

[0057] Through the above scheme, when the target rear vehicle has entered the field of vision of the driver of the vehicle, the driver does not need to continue to use the rearview mirror to observe the target rear vehicle, that is, there is no need to adjust the rearview mirror at this time, thus avoiding useless adjustment operations.

[0058] In some embodiments, step 10A specifically includes:

[0059] Step 10A1, detecting the total length of the target rear vehicle, and determining the rearview mirror field of view corresponding to the target rearview mirror folding angle;

[0060] Step 10A2, detecting a first vehicle length of a target rear vehicle within the field of view of the rearview mirror, and determining a length ratio according to the first vehicle length and the total vehicle length;

[0061] Step 10A3, in response to the length ratio being less than a preset ratio threshold, determining that the target rear vehicle enters into the human eye field of the driver of the vehicle.

[0062] In specific implementation, the vehicle can determine the total length of the target rear vehicle through the driving perception system, specifically, it can use a camera, a laser radar, infrared, etc. The total length of the vehicle is the total length of the target rear vehicle from the front of the target rear vehicle to the rear of the target rear vehicle.

[0063] At the same time, the rearview mirror field of view corresponding to the target rearview mirror folding angle is determined, that is, the field of view that can be observed by the rearview mirror at the target rearview mirror folding angle. The first vehicle length of the target rear vehicle included in the rearview mirror field of view is detected, and the first vehicle length is ratioed to the total vehicle length to obtain a length ratio.

[0064] The length ratio is compared with a preset ratio threshold. If the length ratio is less than the preset ratio threshold, it means that the length of the target rear vehicle within the field of view of the rearview mirror is very short compared to the total length of the target rear vehicle, that is, most of the body of the target rear vehicle has been driven out of the field of view of the rearview mirror, and it can be considered that the target rear vehicle has entered the field of view of the driver of this vehicle.

[0065] Exemplarily, the preset ratio threshold is 30%, the total vehicle length of the target rear vehicle is detected to be 10m, and the first vehicle length of the target rear vehicle contained in the field of view of the rearview mirror is detected to be 2m, then the length ratio is determined to be 20%, which is less than the preset ratio threshold. At this time, it can be considered that most of the body of the target rear vehicle has been driven out of the field of view of the rearview mirror, and then it is determined that the target rear vehicle has entered the field of view of the driver of this vehicle.

[0066] Through the above scheme, by determining the ratio of the body length of the target rear vehicle within the field of view of the rearview mirror to the total body length of the original target rear vehicle, it is judged whether the target rear vehicle has driven out of the field of view of the rearview mirror, and the judgment is more accurate.

[0067] In some embodiments, step 10A specifically includes:

[0068] Step 10AA, determining a rearview mirror field of view corresponding to a target rearview mirror eversion angle, and detecting a second vehicle length of a target rear vehicle contained in the rearview mirror field of view;

[0069] Step 10AB, in response to the second vehicle length being less than a preset length threshold, determining that the target rear vehicle enters the human eye field of the driver of the present vehicle.

[0070] In specific implementation, the rearview mirror field of view corresponding to the target rearview mirror folding angle is determined, that is, the field of view that can be observed by the rearview mirror at the target rearview mirror folding angle. The second vehicle length of the target rear vehicle included in the rearview mirror field of view is detected.

[0071] The second vehicle length is compared with a preset length threshold, which is a length basis for judging whether the target rear vehicle has driven out of the field of view of the rearview mirror. If it is determined that the second vehicle length is less than the preset length threshold, it can be considered that most of the target rear vehicle has driven out of the field of view of the rearview mirror, and then the target rear vehicle is determined to have entered the field of view of the driver of the vehicle.

[0072] Exemplarily, the preset length threshold is 2m. If the second vehicle length of the target rear vehicle contained in the field of view of the rearview mirror is detected to be 1m, it can be considered that most of the body of the target rear vehicle has already driven out of the field of view of the rearview mirror, and then the target rear vehicle is determined to have entered the field of view of the driver of this vehicle.

[0073] Through the above scheme, by determining the body length of the target rear vehicle within the field of view of the rearview mirror, it is judged whether the target rear vehicle has driven out of the field of view of the rearview mirror. The parameters obtained and the amount of calculation are smaller, the judgment efficiency is improved, and the judgment is more accurate.

[0074] In some embodiments, step 10B specifically includes:

[0075] Step 10B1, in response to the judgment result that there is no new target rear vehicle, controlling the rearview mirror of the vehicle to adjust back to the current angle. Or,

[0076] Step 10B2, in response to the judgment result that there is a new target rear vehicle, determine the new following distance between the new target rear vehicle and the vehicle, determine the new target rearview mirror tumbling angle according to the new following distance, and control the rearview mirror of the vehicle to adjust from the target rearview mirror tumbling angle to the new target rearview mirror tumbling angle.

[0077] In specific implementation, if it is determined that the target rear vehicle enters the field of vision of the driver of this vehicle, the driver of this vehicle can directly observe the target rear vehicle with his eyes without the assistance of the rearview mirror. Therefore, the rearview mirror no longer needs to monitor the position of the target rear vehicle.

[0078] Determine whether there is a new vehicle behind the vehicle whose following distance is less than a preset distance threshold. If not, it means that there is no vehicle behind the vehicle that requires the user to pay close attention through the rearview mirror. Therefore, the rearview mirror can be controlled to adjust back to the initial angle before adjustment, that is, the current angle described in step 1022.

[0079] If there is a new rear vehicle whose following distance to the vehicle is less than a preset distance threshold, the rear vehicle will be taken as a new target rear vehicle, and the position of the new target rear vehicle will continue to be monitored to determine a new following distance between the new target rear vehicle and the vehicle, and a new target rearview mirror tumbling angle will be determined based on the new following distance, and the rearview mirror of the vehicle will be controlled to adjust from the target rearview mirror tumbling angle to the new target rearview mirror tumbling angle.

[0080] It can be understood that because the new target rear vehicle is located relatively rearward compared to the target rear vehicle, the new target rearview mirror tumbling angle may be smaller than the target rearview mirror tumbling angle. At this time, the rearview mirror of the vehicle is controlled to be adjusted from the target rearview mirror tumbling angle to the new target rearview mirror tumbling angle, which is equivalent to controlling the rearview mirror of the vehicle to flip inward.

[0081] Through the above scheme, if it is determined that the target rear vehicle has entered the human eye field of the driver of the vehicle, it can be determined whether there is a new rear vehicle whose following distance from the vehicle is less than the preset distance threshold, and then the rearview mirror can be further controlled and adjusted to make the adjustment more accurate. At the same time, if there is no new target rear vehicle, there is no need to continue to turn the rearview mirror outward to a larger angle to obtain a farther field of view, and the rearview mirror can be controlled to return to the angle before adjustment.

[0082] In some embodiments, step 102 specifically includes:

[0083] Step 102A, obtaining the speed limit of the road where the vehicle is located;

[0084] Step 102B, in response to the vehicle being in a driving state, determining that a preset rearview mirror adjustment condition is satisfied;

[0085] Step 102C: compare the vehicle speed with the road speed limit to obtain a comparison result, and adjust the rearview mirror of the vehicle according to the comparison result.

[0086] In specific implementation, since the vehicle may not have a driving perception system or cannot determine the distance information between the rear vehicle and the vehicle, the corresponding rearview mirror adjustment method can be determined by the vehicle's driving speed. The road speed limit value of the road where the vehicle is located is obtained. The road speed limit value is the maximum speed of the vehicle when driving on the road. The road speed limit values ​​of different roads are different.

[0087] When it is determined that the vehicle is in a driving state, the rearview mirror can be adjusted at this time, that is, the rearview mirror adjustment condition is met. The vehicle speed is compared with the road speed limit, and the adjustment method of the rearview mirror is further determined according to the comparison result. The specific process is as follows:

[0088] Step a, in response to the vehicle speed being less than the road speed limit, determining the rearview mirror flip-up angle according to the vehicle speed, and controlling the rearview mirror of the vehicle to flip upward from the current angle to the rearview mirror flip-up angle; or,

[0089] Step b, in response to the vehicle speed being greater than or equal to the road speed limit, determining a rearview mirror downward folding angle according to the vehicle speed, and controlling the rearview mirror of the vehicle to flip downward from a current angle to the rearview mirror downward folding angle.

[0090] Specifically, if the vehicle's driving speed is less than the road speed limit, it means that the rear vehicle may catch up with the vehicle at a faster speed, that is, the speed difference between the rear vehicle and the vehicle may be large. Therefore, the driver of the vehicle needs to pay attention to the vehicles farther behind. Therefore, the rearview mirror flip-up angle is determined according to the vehicle's driving speed, and the rearview mirror of the vehicle is controlled to flip upward from the current angle to the rearview mirror flip-up angle.

[0091] For example, the road speed limit is 100km / h, and the vehicle is traveling at 60km / h. At this time, the vehicle behind the vehicle may pass by the vehicle at a speed close to 100km / h. Therefore, the driver of the vehicle needs to pay attention to vehicles farther away. Therefore, the rearview mirror flip-up angle corresponding to the vehicle's driving speed is determined, and the rearview mirror is controlled to flip upward to the rearview mirror flip-up angle, so that the center of vision moves farther away, so that the driver of the vehicle can observe farther areas.

[0092] If the vehicle speed is greater than or equal to the road speed limit, the vehicle speed is relatively fast and the driver of the vehicle needs to pay more attention to other traffic participants in the close range around the vehicle. Therefore, the rearview mirror downward angle is determined according to the vehicle speed, and the rearview mirror of the vehicle is controlled to flip downward from the current angle to the rearview mirror downward angle, so that the driver of the vehicle can see the area in the close range of the vehicle through the rearview mirror.

[0093] Through the above solution, since the vehicle may not have a driving perception system or cannot determine the distance information between the rear vehicle and the vehicle, the corresponding rearview mirror adjustment method can be determined by the vehicle's driving speed. The rearview mirror is controlled to flip up and down according to the vehicle's driving speed, so that the user can see a more appropriate field of view at different vehicle speeds.

[0094] In some embodiments, before step 101, the method further includes:

[0095] Step 100, in response to receiving an automatic rearview mirror adjustment instruction, turning on a rearview mirror adjustment function.

[0096] In specific implementation, after receiving the command for automatic adjustment of the rearview mirror, the rearview mirror adjustment function is turned on to achieve automatic adjustment of the rearview mirror when the corresponding conditions are met, without the need for user intervention. That is, when receiving the command issued by the user, the rearview mirror adjustment function is turned on to achieve the judgment of the vehicle speed or the distance between the rear vehicle and the rear vehicle, that is, automatically judge whether the rearview mirror adjustment conditions are met and adjust the rearview mirror when the conditions are met.

[0097] Among them, the triggering and sending methods of automatically adjusting the rearview mirror command include at least one of the following: clicking a virtual button on the central control screen in the car, pressing a physical button in the car, calling for it to be turned on through a voice command, pressing a corresponding button on the steering wheel, and through trigger gestures pre-stored in the car computer, such as raising your hand, facing your palm towards the camera device in the car, etc.

[0098] In some embodiments, after the rearview mirror adjustment function is turned on in step 100, a first prompt message is sent, wherein the first prompt message is used to prompt that the rearview mirror adjustment function has been turned on. The prompting method of the first prompt message includes at least one of the following: voice broadcast, HUD display, instrument display, central control screen display, window display, and in-vehicle device linkage, etc. The HUD display is a head-up display. The first prompt message prompts the user that the rearview mirror adjustment function has been turned on, and the automatic adjustment of the rearview mirror can be realized later, avoiding the user from manually adjusting the rearview mirror, avoiding distracting the user's attention, and reducing safety hazards.

[0099] Similarly, when the rearview mirror is adjusted as mentioned above, a corresponding prompt message can be sent to remind the user that the rearview mirror is about to be adjusted, thereby improving the usability of the system. The prompt message may be provided in at least one of the following ways: voice broadcast, HUD display, instrument display, central control screen display, window display, and linkage with in-vehicle equipment.

[0100] Exemplarily, when the prompting method of the prompting information is voice broadcast, when it is detected that the vehicle speed or the distance between the rear vehicle and the rear vehicle meets the adjustment conditions, the voice broadcasts the prompting information of "the rearview mirror will be adjusted for you soon".

[0101] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as a computer or a server. The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.

[0102] It should be noted that the above describes some embodiments of the present disclosure. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
