Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of vehicle control, and particularly relates to a rearview mirror control method and a vehicle. BACKGROUND

[0002] With the rapid development of the field of vehicle technology, vehicles have become an important means of transportation in people's daily life. When a user drives a vehicle, in some scenarios such as turning and changing lanes, the user needs to observe the rear vehicle to avoid traffic accidents.

[0003] Currently, users usually use a rearview mirror to observe the rear vehicle, but due to the limited field of view of the rearview mirror, there is a blind area in the field of view, which forms a safety hazard. SUMMARY

[0004] Therefore, the present disclosure aims to provide a rearview mirror control method and a vehicle to solve the problem that the current user usually uses a rearview mirror to observe the rear vehicle, but due to the limited field of view of the rearview mirror, there is a blind area in the field of view, which forms a safety hazard.

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

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

[0007] determining that the vehicle driving speed or the following distance satisfies a preset rearview mirror adjustment condition, and adjusting a rearview mirror of the host vehicle.

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

[0009] a data acquisition module configured to obtain a vehicle driving speed of the host vehicle, or a following distance between a target rear vehicle and the host vehicle, wherein the target rear vehicle is the closest rear vehicle to the host vehicle;

[0010] a rearview mirror adjustment module configured to determine that the vehicle driving speed or the following distance satisfies a preset rearview mirror adjustment condition, and adjust a rearview mirror of the host vehicle.

[0011] Based on the same inventive concept, a third aspect of the present disclosure provides 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.

[0012] Based on the same inventive concept, a fourth aspect of the present disclosure provides a non-transitory computer-readable storage medium storing computer instructions for causing a computer to execute the rearview mirror control method as described above.

[0013] Based on the same inventive concept, a fifth aspect of the present disclosure provides a vehicle comprising the rearview mirror control device of the second aspect or the electronic device of the third aspect or the storage medium of the fourth aspect.

[0014] As can be seen from the above, the present disclosure provides a rearview mirror control method and a vehicle. The vehicle driving speed of the host vehicle or the following distance between the target rear vehicle and the host vehicle is obtained. Since there can be multiple vehicles behind the host vehicle, the host vehicle mainly considers the vehicle farthest away from itself when driving. Therefore, the target rear vehicle is selected as the vehicle farthest away from the host vehicle. It is determined whether the vehicle driving speed or the following distance meets the preset rearview mirror adjustment condition. At this time, the rearview mirror should be adjusted to eliminate a certain blind spot and avoid the problem of fixed safety hazards in the field of view of the rearview mirror, thereby improving the safety of driving.

[0019] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, the following will further describe the present disclosure in combination with specific embodiments and with reference to the drawings.

[0021] With the rapid development of the vehicle technology field, vehicles have become an important means of transportation in people's daily life. When a user drives a vehicle, in some scenarios such as turning and changing lanes, the user needs to observe the oncoming vehicle to avoid traffic accidents.

[0022] Currently, users usually use rearview mirrors to observe the rear vehicle, but due to the limited field of view of the rearview mirror, there is a blind spot in the field of view, which forms a safety hazard.

[0023] Based on the above description, the embodiments of the present disclosure provide a rearview mirror control method, as shown in Figure 1 The method comprises the following steps:

[0024] In step 101, the vehicle speed of the host vehicle or the following distance between the target rear vehicle and the host vehicle is obtained, wherein the target rear vehicle is the rear vehicle closest to the host vehicle.

[0025] In implementation, the vehicle speed of the host vehicle can be obtained by a vehicle sensor. Alternatively, the following distance between the target rear vehicle and the host vehicle can also be obtained. There can be multiple vehicles behind the host vehicle, and for safety considerations, the rear vehicle closest to the host vehicle should be considered first. Therefore, in the embodiments of the present disclosure, the target vehicle is the rear vehicle closest to the host vehicle.

[0026] In the embodiments of the present disclosure, the identification of the target rear vehicle and the determination of the following distance can be realized by the driving perception system of the host vehicle. Specifically, a camera, a laser radar, an infrared ray, or the like can be used.

[0027] In step 102, it is determined whether the vehicle speed or the following distance meets a preset rearview mirror adjustment condition, and the rearview mirror of the host vehicle is adjusted.

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

[0029] Alternatively, it is determined whether the following distance meets the preset rearview mirror adjustment condition. If the rearview mirror adjustment condition is met, it is indicated that the rearview mirror should be adjusted to avoid safety accidents.

[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 distance is a condition related to the distance, which are not the same.

[0031] In this embodiment, the rearview mirror of the vehicle is adjusted, which can mean that the driver-side rearview mirror and the copilot-side rearview mirror are adjusted at the same time, or the rearview mirror to be adjusted can be determined according to the position of the target rear vehicle relative to the vehicle.

[0032] Specifically, if the target rear vehicle is located at the left rear of the vehicle, the rearview mirror to be adjusted is determined to be the driver-side rearview mirror. If the target rear vehicle is located at the right rear of the vehicle, the rearview mirror to be adjusted is determined to be the copilot-side rearview mirror.

[0033] Through the above scheme, the vehicle speed of the vehicle or the following distance between the target rear vehicle and the vehicle is obtained. Since there can be multiple vehicles behind the vehicle, the vehicle mainly considers the vehicle farthest away from itself when driving. Therefore, the target rear vehicle is selected as the vehicle farthest away from the vehicle. It is determined whether the vehicle speed or the following distance meets the preset rearview mirror adjustment condition. At this time, the rearview mirror should be adjusted to eliminate a certain blind area and avoid the problem that the visual range of the rearview mirror is fixed and has a safety hazard, thereby improving the safety of driving.

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

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

[0036] Step 1022, determining a target rearview mirror out-flap angle according to the following distance, and controlling the rearview mirror of the vehicle to be adjusted from a current angle to the target rearview mirror out-flap angle.

[0037] In the 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 indicates that the distance between the target rear vehicle and the vehicle is close, and therefore the driver is more likely to pay attention to the position of the target rear vehicle through the rearview mirror, and thus the rearview mirror should be adjusted at this time, that is, the preset rearview mirror adjustment condition is met, and the preset rearview mirror adjustment condition is that the following distance is less than the preset distance threshold.

[0038] The database stores a corresponding relationship between the following distance and the rearview mirror out-flap angle. When the following distance between the target rear vehicle and the vehicle is determined, the database is searched according to the following distance to determine the target rearview mirror out-flap angle corresponding to the following distance, and the rearview mirror of the vehicle is controlled to be adjusted from the current angle to the target rearview mirror out-flap angle, so that the target rear vehicle is always in the center of the field of view of the rearview mirror when advancing, so as to facilitate the user to observe the target rear vehicle through the rearview mirror.

[0039] It can be understood that the current angle may be less than, greater than, or equal to the target rearview mirror out-flap angle. If the current angle is less than the target rearview mirror out-flap angle, the rearview mirror of the vehicle is controlled to be adjusted from the current angle to the target rearview mirror out-flap angle, which is equivalent to controlling the rearview mirror of the vehicle to be out-flapped to the target rearview mirror out-flap angle. If the current angle is greater than the target rearview mirror out-flap angle, the rearview mirror of the vehicle is controlled to be adjusted from the current angle to the target rearview mirror out-flap angle, which is equivalent to controlling the rearview mirror of the vehicle to be in-flapped to the target rearview mirror out-flap angle.

[0040] In this embodiment, in-flapping and out-flapping mean that the height of the rearview mirror remains unchanged and only flaps left and right. Specifically, if the driver side rearview mirror is adjusted, out-flapping means that the rearview mirror flaps to the left side. If the co-driver side rearview mirror is adjusted, out-flapping means that the rearview mirror flaps to the right side.

[0041] Through the above scheme, the target rearview mirror out-flap angle is adjusted according to the following distance, and because the following distance changes in real time, the corresponding target rearview mirror out-flap angle also changes, realizing dynamic adjustment of the rearview mirror and making the rearview mirror out-flap angle more accurate.

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

[0043] Step 10221, comparing the initial rearview mirror out-flap angle determined according to the following distance with a preset angle threshold.

[0044] Step 10222, in response to the initial rearview mirror out-flap angle being greater than or equal to the preset angle threshold, taking the preset angle threshold as the target rearview mirror out-flap angle; or,

[0045] Step 10223, in response to the initial rearview mirror out-flap angle being less than the preset angle threshold, taking the initial rearview mirror out-flap angle as the target rearview mirror out-flap angle.

[0046] In particular implementation, the initial rearview mirror out-flap angle is determined according to the following distance and a database in which a corresponding relationship between the following distance and the initial rearview mirror out-flap angle is stored.

[0047] The initial rearview mirror out-flap angle is compared with a preset angle threshold, wherein the preset angle threshold represents the maximum out-flap angle of the vehicle rearview mirror under the premise of ensuring safe driving. Since the field of view of the vehicle rearview mirror should include not only the rear vehicle of the host vehicle but also the host vehicle itself, the corresponding out-flap angle of the rearview mirror also has a maximum value.

[0048] If the initial rearview mirror out-flap angle is greater than or equal to the preset angle threshold, that is, the rearview mirror out-flap angle determined according to the following distance is greater than the maximum out-flap angle, the preset angle threshold is therefore taken as the target rearview mirror out-flap angle.

[0049] If the initial rearview mirror out-flap angle is less than the preset angle threshold, the initial rearview mirror out-flap angle can be taken as the target rearview mirror out-flap angle.

[0050] Through the above scheme, by setting the maximum out-flap angle of the rearview mirror, the range that can be seen through the rearview mirror is not blindly pursued, and the host vehicle itself does not exist in the rearview mirror, which avoids causing safety hazards and leads to safety accidents.

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

[0052] Step 10A, determining whether the target rear vehicle enters the human eye field of view of the driver of the host vehicle;

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

[0054] In particular implementation, when the rearview mirror of the host vehicle is controlled to be adjusted from the current angle to the target rearview mirror out-flap angle, the target rear vehicle is continuously monitored to determine whether the target rear vehicle enters the human eye field of view of the driver of the host vehicle, that is, whether the driver of the host vehicle can observe the target rear vehicle through the human eye without the help of the rearview mirror.

[0055] If it is determined that the target rear vehicle has entered the driver's field of view, the driver can directly observe the target rear vehicle through the human eye without the assistance of the rearview mirror, and thus the rearview mirror does not need to monitor the position of the target rear vehicle.

[0056] If a new rear vehicle is determined to exist, the new rear vehicle is taken as a new target rear vehicle, and the position of the new target rear vehicle is continuously monitored, and the rearview mirror is further adjusted.

[0057] According to the above scheme, when the target rear vehicle has entered the driver's field of view, the driver does not need to continuously observe the target rear vehicle through the rearview mirror, that is, the rearview mirror does not need to be adjusted at this time, and useless adjustment operations are avoided.

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

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

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

[0061] Step 10A3, in response to the length ratio being less than a preset ratio threshold, determining that the target rear vehicle has entered the driver's field of view.

[0062] In specific implementation, the driver's perception system can be used to determine the total length of the target rear vehicle, and specifically, a camera, a laser radar, an infrared ray, etc. can be used. 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 tail of the target rear vehicle.

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

[0064] The length ratio is compared with the preset ratio threshold, and if the length ratio is less than the preset ratio threshold, it indicates that the length of the target rear vehicle in the rearview mirror field of view is very short compared with the total length of the target rear vehicle, that is, most of the body of the target rear vehicle has exited the rearview mirror field of view, and thus it can be considered that the target rear vehicle has entered the driver's field of view.

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

[0066] Through the above scheme, by determining the proportion of the body length of the target rear vehicle in the field of view of the rearview mirror to the total body length of the target rear vehicle, it is determined whether the target rear vehicle has exited the field of view of the rearview mirror. The determination 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 out-flap angle, 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 has entered the field of view of the human eye of the driver of the vehicle.

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

[0071] The second vehicle length is compared with the preset length threshold, and the preset length threshold is a length basis for determining whether the target rear vehicle has exited 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 body of the target rear vehicle has exited the field of view of the rearview mirror, and it is further determined that the target rear vehicle has entered the field of view of the human eye of the driver of the vehicle.

[0072] Exemplarily, the preset length threshold is 2m, and if the second vehicle length of the target rear vehicle contained in the field of view of the rearview mirror is 1m, it can be considered that most of the body of the target rear vehicle has exited the field of view of the rearview mirror, and it is further determined that the target rear vehicle has entered the field of view of the human eye of the driver of the vehicle.

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

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

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

[0076] Step 10B2, in response to the result of the judgment 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 out-flap angle according to the new following distance, and control the rearview mirror of the vehicle to adjust from the target rearview mirror out-flap angle to the new target rearview mirror out-flap angle.

[0077] In specific implementation, if it is determined that the target rear vehicle drives into the driver's eye field of view of the vehicle, at this time the driver of the vehicle can directly observe the target rear vehicle through the human eye without the aid of the rearview mirror, so at this time the rearview mirror does not need to monitor the position of the target rear vehicle again.

[0078] It is judged whether there is a new rear vehicle with a following distance less than a preset distance threshold from the vehicle, and if not, it indicates that at this time there is no rear vehicle that needs to be focused on by the user through the rearview mirror, so the rearview mirror can be controlled to adjust back to the initial angle before adjustment, that is, the current angle in step 1022.

[0079] If there is a new rear vehicle with a following distance less than a preset distance threshold from the vehicle, the rear vehicle is taken as a new target rear vehicle, the position of the new target rear vehicle is continuously monitored, the new following distance between the new target rear vehicle and the vehicle is determined, the new target rearview mirror out-flap angle is determined according to the new following distance, and the rearview mirror of the vehicle is controlled to adjust from the target rearview mirror out-flap angle to the new target rearview mirror out-flap angle.

[0080] It can be understood that because the new target rear vehicle is relatively rearward compared with the target rear vehicle, the new target rearview mirror out-flap angle can be less than the target rearview mirror out-flap angle, at this time controlling the rearview mirror of the vehicle to adjust from the target rearview mirror out-flap angle to the new target rearview mirror out-flap angle is equivalent to controlling the rearview mirror of the vehicle to turn inward.

[0081] Through the above scheme, if after it is determined that the target rear vehicle drives into the driver's eye field of view of the vehicle, it is judged whether there is a new rear vehicle with a following distance less than a preset distance threshold from the vehicle, and the rearview mirror is further controlled and adjusted, which is more accurate. At the same time, if there is no new target rear vehicle, at this time the rearview mirror does not need to be continuously out-flapped 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, acquiring a road speed limit value of a road where the vehicle is located;

[0084] In step 102B, in response to the vehicle being in a driving state, it is determined that a preset rearview mirror adjustment condition is met.

[0085] In step 102C, the vehicle driving speed is compared with the road speed limit value to obtain a comparison result, and the rearview mirror of the vehicle is adjusted according to the comparison result.

[0086] In a specific implementation, the vehicle can not have a driving perception system, or the distance information between the rear vehicle and the vehicle cannot be determined. In this case, the corresponding rearview mirror adjustment mode can be determined by the vehicle driving speed. The road speed limit value of the road where the vehicle is located is obtained, and the road speed limit value is the maximum speed of the vehicle 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, that is, the rearview mirror adjustment condition is met. The vehicle driving speed is compared with the road speed limit value, and the adjustment mode of the rearview mirror is further determined according to the comparison result. The specific process is as follows:

[0088] In step a, in response to the vehicle driving speed being less than the road speed limit value, the rearview mirror upward turning angle is determined according to the vehicle driving speed, and the rearview mirror of the vehicle is controlled to turn upward from the current angle to the rearview mirror upward turning angle; or,

[0089] In step b, in response to the vehicle driving speed being greater than or equal to the road speed limit value, the rearview mirror downward turning angle is determined according to the vehicle driving speed, and the rearview mirror of the vehicle is controlled to turn downward from the current angle to the rearview mirror downward turning angle.

[0090] Specifically, if the vehicle driving speed is less than the road speed limit value, it indicates that the rear vehicle can catch up with the vehicle at a faster speed, that is, the speed difference between the rear vehicle and the vehicle can be large, and therefore the driver of the vehicle needs to pay attention to the vehicle far away in the rear. Therefore, the rearview mirror upward turning angle is determined according to the vehicle driving speed, and the rearview mirror of the vehicle is controlled to turn upward from the current angle to the rearview mirror upward turning angle.

[0091] For example, the road speed limit value is 100 km / h, and the driving speed of the vehicle is 60 km / h. At this time, the rear vehicle of the vehicle can pass the vehicle at a speed close to 100 km / h, and therefore the driver of the vehicle needs to pay attention to the vehicle far away. Therefore, the rearview mirror upward turning angle corresponding to the driving speed of the vehicle is determined, and the rearview mirror is controlled to turn upward to the rearview mirror upward turning angle, so that the center of the field of view moves to a farther place, so that the driver of the vehicle can observe a farther area.

[0092] If the vehicle speed is greater than or equal to the road speed limit value, the vehicle speed is relatively high, the driver of the vehicle needs to pay more attention to other traffic participants in the close range around the vehicle, and therefore the down angle of the rearview mirror is determined according to the vehicle speed, the rearview mirror of the vehicle is controlled to be flipped down from the current angle to the down angle of the rearview mirror, so that the driver of the vehicle can view the area in the close range of the vehicle through the rearview mirror.

[0093] Through the above scheme, if the vehicle does not have a driving perception system or cannot determine the distance information between the rear vehicle and the vehicle, the corresponding rearview mirror adjustment mode can be determined through the vehicle speed. The rearview mirror is controlled to be flipped up and down to enable the user to view a more appropriate field of view at different speeds.

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

[0095] Step 100, in response to receiving the automatic adjustment of the rearview mirror instruction, the rearview mirror adjustment function is started.

[0096] In specific implementation, after receiving the automatic adjustment of the rearview mirror instruction, the rearview mirror adjustment function is started to realize automatic adjustment of the rearview mirror without user intervention when the corresponding conditions are met. That is, when the user's instruction is received, the rearview mirror adjustment function is started, the judgment of the vehicle speed or the distance between the rear vehicle and the vehicle is realized, that is, the judgment of whether the rearview mirror adjustment condition is met and the adjustment of the rearview mirror when the condition is met is automatically performed.

[0097] The trigger sending mode of the automatic adjustment of the rearview mirror instruction includes at least one of the following: clicking a virtual button on the center control screen in the vehicle, pressing a physical button in the vehicle, calling to open through a voice instruction, pressing a corresponding key on the steering wheel, and triggering a gesture stored in advance in the vehicle machine, such as raising a hand, and facing a palm towards the in-vehicle camera.

[0098] In some embodiments, after step 100 starts the rearview mirror adjustment function, a first prompt information is sent, wherein the first prompt information is used to prompt that the rearview mirror adjustment function has been started. The prompt mode of the first prompt information includes at least one of the following: voice broadcast, HUD display, instrument display, center control screen display, vehicle window display, and in-vehicle equipment linkage. The HUD display is a head-up display. The first prompt information prompts the user that the rearview mirror adjustment function has been started, and subsequent automatic adjustment of the rearview mirror can be realized, avoiding manual adjustment of the rearview mirror by the user, avoiding distraction of the user, and reducing safety hazards.

[0099] Similarly, when the rearview mirror is adjusted as described above, corresponding prompt information can be sent to remind the user that the rearview mirror is about to be adjusted, thereby improving the ease of use of the system. The prompt manner of the prompt information includes at least one of the following: voice broadcast, HUD display, instrument display, central screen display, window display, and in-vehicle device linkage.

[0100] For example, when the vehicle speed or the following distance of the rear vehicle satisfies the adjustment condition, the prompt information "the rearview mirror is about to be adjusted for you" is broadcasted by voice.

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

[0102] It should be noted that some embodiments of the present disclosure have been described above. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims can be performed in a different order than the order described above and still achieve desirable results.
