The visual information of the vehicle to the external environment may include visual information of the vehicle to a target obstacle, visual information of the vehicle to a lane marker, and the like.

The target obstacle may be various obstacles that can approach the rear view mirror of the vehicle. For example, when a vehicle meets, the target obstacle is an opponent vehicle that meets the vehicle; the target obstacle is a toll booth when the vehicle passes through an artificial toll lane of a toll booth.

An information acquisition module may be provided on the vehicle to acquire external environmental information of the vehicle. For example, a camera, radar and navigation module may be provided. The visual information of the vehicle to the external environment can be acquired through the camera; distance information between the vehicle and a target obstacle can be acquired through a radar and a camera, wherein the radar can be a common radar or a laser radar; the position information of the vehicle can be obtained by the navigation module.

In the present embodiment, the external environment information includes visual information of the vehicle on the external environment and distance information of the vehicle from the target obstacle. As shown in fig. 2, step 120 may include the steps of:

and step 122, if the fact that the vehicle is close to the target obstacle is judged according to the visual information and the distance information, controlling the rearview mirror of the vehicle to be folded.

After the visual information is obtained by the camera, the target obstacle can be identified by a machine learning model or a deep learning model, and then the distance information between the vehicle and the target obstacle is determined by the radar.

When the vehicle is judged to be close to the target obstacle according to the visual information and the distance information, the fact that the rearview mirror of the vehicle is easy to touch the target obstacle or the vehicle needs to be far away from the target obstacle is explained, and the rearview mirror of the vehicle needs to be folded in order to avoid the rearview mirror of the vehicle from touching the target obstacle or enabling the vehicle to approach the target obstacle.

Fig. 3 is a flowchart illustrating steps prior to step 122 according to one embodiment shown in the embodiment of fig. 2. In the present embodiment, the external environmental information further includes position information of the vehicle. As shown in fig. 3, before step 122, the method further includes:

and step 121, judging whether the vehicle is in a preset running area or not according to the position information of the vehicle.

Step 122 is performed in the event that it is determined that the vehicle is within the predetermined travel area.

In the step, whether the vehicle is in the preset driving area or not is judged according to the position information of the vehicle, so that the vehicle can obtain the environment condition of the area where the vehicle is located in advance, and therefore preparation is made for sending an instruction of folding the rearview mirror, and the time for controlling the rearview mirror to fold by the vehicle is more accurate.

In some embodiments of the present application, the controlling the folding of the rearview mirror of the vehicle if it is determined that the vehicle is close to the target obstacle according to the visual information and the distance information includes:

if the distance between the vehicle and the target obstacle is judged to be below a first preset distance according to the visual information and the distance information, the current speed of the vehicle is obtained;

judging whether the current speed of the vehicle is below a first preset speed or not;

if yes, judging that the vehicle is close to the target obstacle, and controlling the folding of the rearview mirror of the vehicle.

The first predetermined distance may be 5m and the first predetermined vehicle speed may be 20 km/h.

When the distance between the vehicle and the target obstacle is close enough and the current speed of the vehicle is low enough, the vehicle is approaching the target obstacle, and the folding of the rearview mirror of the vehicle is controlled at the moment, so that the vehicle can further approach the target obstacle, and the passing performance of the vehicle is improved.

And 123, if the vehicle is judged to be far away from the target obstacle according to the visual information and the distance information, controlling the rearview mirror of the vehicle to be unfolded.

When it is determined that the vehicle is far from the target obstacle, the rearview mirror of the vehicle is unfolded so that the rearview mirror of the vehicle can be normally used.

Step 122 and step 123 do not have a specific sequence, and in practical cases, the two steps may be executed alternately.

In some embodiments of the present application, the predetermined driving area is a construction site area, the target obstacle is a counterpart vehicle that meets the vehicle, and if it is determined that the vehicle is far from the target obstacle according to the visual information and the distance information, the controlling of the mirror of the vehicle to be deployed includes:

acquiring the current speed of the vehicle;

and if the current speed of the vehicle exceeds a second preset speed and the driver's cab of the vehicle is judged to be staggered with the tail of the opposite vehicle according to the visual information and the distance information, controlling the rearview mirror of the vehicle to be unfolded.

The second preset vehicle speed can also be 20km/h, and the second preset vehicle speed is the same as the first preset vehicle speed; the second predetermined vehicle speed may also be different from the first predetermined vehicle speed.

The distance and the direction relation between the vehicle and the opposite vehicle can be obtained according to the visual information and the distance information, and whether the cab of the vehicle is staggered with the tail of the opposite vehicle can be further judged.

When the current vehicle speed of the vehicle exceeds a second preset vehicle speed and the cab of the vehicle is staggered with the tail of the opposite vehicle, the meeting is finished, and at the moment, the rearview mirror of the vehicle is unfolded to enable the user to normally use the rearview mirror of the vehicle.

In some embodiments of the present application, the predetermined driving area is a toll booth area, the target obstacle is a handrail in the toll booth, and if it is determined that the vehicle is far from the target obstacle according to the visual information and the distance information, the controlling of the unfolding of the rearview mirror of the vehicle includes:

acquiring the current speed of the vehicle;

and if the current speed of the vehicle exceeds a fourth preset speed and the vehicle is judged to have passed the railing according to the visual information and the distance information, controlling the rearview mirror of the vehicle to be unfolded.

The fourth predetermined vehicle speed may be 10 km/h. The fourth predetermined vehicle speed may be the same as the second predetermined vehicle speed and/or the first predetermined vehicle speed, or may be different from both the second predetermined vehicle speed and the first predetermined vehicle speed.

The railing in the toll station is the upper railing of the railing machine for controlling the vehicle to pass in the toll station. For example, when the position of the railing is changed from being located at the front side of the vehicle to being located at the rear side of the vehicle according to the visual information, and the distance between the position of the railing and the railing is changed from small to large, the fact that the vehicle passes through the railing is indicated.

When the vehicle does not pass through the railing, the fact that the vehicle needs to be close to the artificial window of the toll station is indicated, and the rearview mirror of the vehicle is controlled to be folded at the moment, so that a driver can get close to the artificial window in the vehicle; in order to enable a user to use the rearview mirror during normal vehicle driving, the folded rearview mirror of the vehicle needs to be unfolded after the vehicle passes through the railing, which indicates that the payment is finished.

In some embodiments of the present application, corresponding to the above-mentioned embodiments, before obtaining the current vehicle speed of the vehicle if it is determined that the distance between the vehicle and the target obstacle is below a first predetermined distance according to the visual information and the distance information, the method further includes:

and judging whether the vehicle enters an artificial toll lane, wherein if the distance between the vehicle and a target obstacle is judged to be less than or equal to a first preset distance according to the visual information and the distance information, the current speed of the vehicle is acquired under the condition that the vehicle is judged to enter the artificial toll lane.

The position information of the vehicle can be acquired, and whether the vehicle enters the artificial toll lane or not can be judged according to the position information of the vehicle.

Whether the vehicle enters the artificial toll lane or not is judged in advance, and then the vehicle is judged when entering the artificial toll lane, purposeful preparation can be carried out aiming at the scene that the vehicle enters and exits the toll station, so that the time for controlling the rearview mirror to fold and unfold by the vehicle is more accurate.

In some embodiments of the present application, the obtaining of the visual information and the distance information is performed in a case where it is determined that the vehicle enters an artificial toll lane or that the vehicle is within a predetermined travel area.

In the embodiment, the visual information and the distance information are acquired when the vehicle enters the manual toll lane or the vehicle is in the preset driving area, so that the data volume for acquiring the visual information and the distance information is reduced, and the resource cost is saved.

In some embodiments of the present application, the predetermined driving area is a toll booth area, the target obstacle is a toll booth, and if it is determined that the vehicle is close to the target obstacle according to the visual information and the distance information, the controlling the folding of the rearview mirror of the vehicle includes:

judging whether the vehicle passes through an ETC lane or not according to the visual information and/or the position information of the vehicle;

if not, acquiring the current speed of the vehicle;

if the current speed of the vehicle is below a third preset speed and the distance between the vehicle and the toll station sentry box is judged to be below a second preset distance according to the visual information and the distance information, judging that the vehicle is close to a target obstacle, and controlling the folding of a rearview mirror of the vehicle;

if the vehicle is judged to be far away from the target obstacle according to the visual information and the distance information, the rearview mirror of the vehicle is controlled to be unfolded, and the method comprises the following steps:

and if the distance between the vehicle and the toll station sentry box exceeds a third preset distance according to the distance information, controlling the rearview mirror of the vehicle to be unfolded.

For example, it is recognized by the visual information that the lane through which the vehicle passes does not have the ETC sign, and it can be determined that the lane through which the vehicle passes is not the ETC lane. For another example, whether the lane passed by the vehicle is an ETC lane is accurately determined by the GPS module in combination with the electronic map.

The third predetermined vehicle speed may be 20km/h, and the third predetermined vehicle speed may be the same as the first predetermined vehicle speed and/or the second predetermined vehicle speed, or may be different from the first predetermined vehicle speed and the second predetermined vehicle speed. The second predetermined distance and the third predetermined distance may both be 0.5m, and the second predetermined distance and the third predetermined distance may be the same or different.

After the vehicle is judged to pass through the manual toll lane, the current speed of the vehicle is judged to be below a third preset speed and the distance between the vehicle and the toll station sentry box is judged to be below a second preset distance, the vehicle is close to the toll station sentry box, and in order to enable a driver to approach an artificial window of the toll station sentry box in the vehicle, a rearview mirror of the vehicle needs to be folded; when the distance between the vehicle and the toll booth exceeds a third predetermined distance, which indicates that the vehicle is far away from the toll booth, it is necessary to control the unfolding of the rear view mirror of the vehicle in order to enable the user to use the rear view mirror normally.

Fig. 4 is a flowchart of a vehicle mirror control method in another exemplary embodiment of the present application. Referring to fig. 4, a method for controlling a rearview mirror of a vehicle during a vehicle meeting is shown, which specifically includes the following steps: entering a meeting program, judging whether the vehicle is in a construction site area, if so, judging whether the distance between the vehicle and a front vehicle is below 5m, otherwise, not folding a rearview mirror; if the distance between the front vehicle and the front vehicle is less than 5m, judging whether the current vehicle speed is less than 20km/h, and if not, not folding the rearview mirror; if the current vehicle speed is below 20km/h, folding the rearview mirror, otherwise, not folding the rearview mirror; after the rearview mirror is folded, whether the current speed is more than 20km/h and the cab is staggered with the tail of the opposite vehicle is judged, if so, the rearview mirror is unfolded, otherwise, the rearview mirror is not unfolded.

Therefore, through the process, the rearview mirror is folded when the vehicle meets other vehicles, and the rearview mirror is unfolded when the vehicle meets the other vehicles, so that the passing performance of the vehicle is improved, and the convenience of meeting the vehicle is improved.

Fig. 5 is a flowchart of a vehicle mirror control method in another exemplary embodiment of the present application. Referring to fig. 5, a method for controlling a rearview mirror of a vehicle when the vehicle passes through a toll station is shown, which specifically includes the following steps: after the vehicle enters the toll station, judging whether the vehicle passes through an ETC lane, if so, judging whether a railing is automatically lifted, otherwise, judging whether the current vehicle speed is below 20 km/h; if the railing is automatically lifted, the vehicle enters a normal ETC lane, the rearview mirror is not folded at the moment, if the railing is not automatically lifted, the vehicle enters an artificial toll collection lane with the ETC lane function, and at the moment, whether the current vehicle speed is below 20km/h is judged; if the current speed is below 20km/h, judging whether the transverse distance between the vehicle and the toll booth is below 0.5m, otherwise, not folding the rearview mirror; if the transverse distance between the vehicle and the toll station sentry box is below 0.5m, the vehicle is close to the toll station sentry box, the rearview mirror is folded, otherwise, the rearview mirror is not folded; after the rearview mirror is folded, whether the transverse distance between the vehicle and the toll station sentry box exceeds 0.5m or not is judged, if yes, the vehicle is far away from the toll station sentry box, the rearview mirror is unfolded at the moment, and otherwise, the rearview mirror is not unfolded.

Therefore, through the process, the vehicle can be folded when passing through the manual toll lane and being close to the toll station sentry box, so that the driver can be close to the manual window of the sentry box in the vehicle, and the rearview mirror can be unfolded when being far away from the toll station sentry box, so that the rearview mirror can be normally used, and the convenience of the vehicle when passing through the toll station is improved.
