[0055] Exemplary Implementation Environment

[0056] Please refer to Figure 1 , Figure 1 It is a schematic diagram of an implementation environment involved in the present invention.

[0057] like Figure 1 As shown, the implementation environment of the embodiment of the present invention involves a server 10 and a vehicle 20. The rearview mirror of the vehicle 20 may include a left rearview mirror, an inner rearview mirror and a right rearview mirror, wherein the inner rearview mirror is also called an interior rearview mirror or a central rearview mirror, and is a device for allowing the driver to observe the situation behind the vehicle 20. The inner rearview mirror is usually installed on the top of the vehicle 20, below the windshield, and is located at the center of the rear of the vehicle. The inner rearview mirror can adjust the angle up and down, left and right, so that the driver can clearly see the field of view behind the vehicle. A motor is installed inside the rearview mirror, which can drive the mirror surface of the rearview mirror to move in the front and back, left and right directions. The vehicle 20 can also be equipped with a vehicle 20 vehicle control unit (VCU) for obtaining driving information of the vehicle 20, such as: driving scene, direction angle of the steering wheel, etc., and sending the driving information to the server 10, so that the server 10 generates a first parameter or a second parameter according to the driving information and the driver's eye distance information, generates an adjustment instruction, and sends it to the VCU, and the VCU controls the motor of the rearview mirror to adjust the field of view of the rearview mirror.

[0058] The server 10 may be an independent physical server 10, or a server 10 cluster or distributed system composed of multiple physical servers 10, or a cloud server 10 that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The server 10 may also become a node of the blockchain.

[0059] The server 10 may be one or more servers. When there are multiple servers 10, there are at least two servers 10 for providing different services, and / or there are at least two servers 10 for providing the same service, such as providing the same service in a load balancing manner, which is not limited in the embodiment of the present invention.

[0060] Exemplary Methods

[0061] Figure 2 This is a flow chart of the goose rearview mirror adjustment method provided by an embodiment of the present invention. Figure 2 In an exemplary embodiment, a rearview mirror adjustment method is provided, and the method may include the following steps:

[0062] S210: Acquire the driving scene of the vehicle and the driver's eye distance.

[0063] The vehicle's driving scenes can include flat road scenes, merging scenes, and ramp scenes. Among them, the flat road scene is the scene most used by drivers. When the driver enters the cockpit of the vehicle, he can adjust the rearview mirror. The merging scene can be a lane change when the vehicle is driving on a highway. The ramp scene can be a scene when the vehicle is going uphill or downhill.

[0064] The driver's eye distance may be the distance between the driver's eyes and the image acquisition device. The image acquisition device may be a camera, through which the distance between the driver's eyes and the camera may be acquired.

[0065] Figure 3 A schematic diagram of the layout of the image acquisition device provided for the implementation of the present invention. Figure 3 As shown, the camera may be a DMS camera. A driver monitoring system (DMS) camera is a camera installed inside a vehicle, mainly used to monitor the driver's behavior and status to ensure driving safety. The distance from the driver's eyes to the camera may be obtained through the DMS camera. It should be noted that the driver's eyes in the embodiment of the present invention may be the driver's pupils.

[0066] S230: Determine a first parameter for adjusting a rearview mirror based on the driver's eye distance.

[0067] S250: Determine a second parameter for adjusting a rearview mirror based on the driving scenario.

[0068] S270: Adjust the rearview mirror based on the first parameter or the second parameter.

[0069] The first parameter may include parameters for adjusting the left rearview mirror, adjusting the parameters for adjusting the interior rearview mirror, and adjusting the parameters for adjusting the right rearview mirror. In different driving scenarios, the rearview mirrors are adjusted differently. For example, in a merging scenario, only the left rearview mirror may be adjusted. In a ramp scenario, the left rearview mirror, the right rearview mirror, and the interior rearview mirror may be adjusted at the same time.

[0070] The angle of the rearview mirror in the embodiment of the present invention can be driven by a motor. Each rearview mirror is adjusted by two motors, wherein the first motor is used to drive the mirror surface to move in the longitudinal front-to-back direction, and the second motor is used to drive the mirror surface to move in the lateral left-to-right direction.

The rearview mirror adjustment method provided by the embodiment of the present invention can achieve the driver's field of view angle without manual adjustment of the inside and outside rearview mirrors, and the driver's field of view of the inside and outside rearview mirrors is always in the best position without blind spots, thereby improving driving safety.

[0072] In one embodiment, determining a first parameter of a rearview mirror based on the driver's eye distance includes:

[0073] Determining, according to the driver's eye distance, a first distance between the driver and the left rearview mirror, a second distance between the driver and the interior rearview mirror, and a third distance between the driver and the right rearview mirror;

[0074] Determining a first parameter of a left rearview mirror according to the first distance;

[0075] determining a first parameter of the interior rearview mirror according to the second distance;

[0076] A first parameter of the right rearview mirror is determined according to the third distance.

[0077] Figure 4 Schematic diagram of the layout of rearview mirrors provided in an embodiment of the present invention. Figure 4 As shown, when the driver enters the cockpit of the vehicle, determining the first distance between the driver and the left rearview mirror according to the driver's eye distance may include:

[0078] Get the current angle of the left rearview mirror;

[0079] The first distance is determined according to the angle between the driver's eye distance and the left rearview mirror.

[0080] In practical applications, determining the first parameter of the left rearview mirror according to the first distance may include an up-and-down adjustment angle and a left-and-right adjustment angle of the left rearview mirror.

[0081] Determining a second distance between the driver and the interior rearview mirror according to the driver's eye distance may include:

[0082] Get the current angle of the interior rearview mirror;

[0083] The second distance is determined according to the angle between the driver's eye distance and the interior rearview mirror.

[0084] In practical applications, determining the first parameter of the interior rearview mirror according to the second distance may include an up-and-down adjustment angle and a left-and-right adjustment angle of the interior rearview mirror.

[0085] Determining the third distance between the driver and the right rearview mirror according to the driver's eye distance may include:

[0086] Get the current angle of the right rearview mirror;

[0087] The third distance is determined according to the angle between the driver's eyes and the right interior rearview mirror.

[0088] In practical applications, determining the first parameter of the right rearview mirror according to the third distance may include an up-and-down adjustment angle and a left-and-right adjustment angle of the right rearview mirror.

[0089] In one embodiment, determining a first parameter of a left rearview mirror according to a first distance; determining a first parameter of an interior rearview mirror according to a second distance; and determining a first parameter of a right rearview mirror according to a third distance include:

[0090] According to the first distance, determining a first adjustment angle corresponding to the first distance in a first data packet; the first data packet is a mapping relationship between the first distance and the adjustment angle of the left rearview mirror;

[0091] Determine, according to the second distance, a second adjustment angle corresponding to the second distance in a second data packet; the second data packet is a mapping relationship between the second distance and the adjustment angle of the rearview mirror;

[0092] According to the third distance, a third adjustment angle corresponding to the third distance in the third data packet is determined; the third data packet is a mapping relationship between the third distance and the adjustment angle of the right rearview mirror.

[0093] The first data packet, the second data packet and the third data packet may be calibrated in advance. The calibration process may include:

[0094] The height of the dummy ranges from 145 to 190 cm, which can cover 95% of the population. The distance of the dummy's eyeballs ranges from 55 to 75 mm, which can cover 95% of the population. The distance from the dummy's eyes to the left rearview mirror is variable X, i.e. the first distance. The distance from the dummy's eyes to the interior rearview mirror is variable Y, i.e. the second distance. The distance from the dummy's eyes to the right rearview mirror is variable Z, i.e. the third distance. The distance from the dummy's eyes to the DMS camera is variable M, i.e. the driver's eye distance. The specific positions of variables X, Y, and Z are determined by the size of the vehicle and the layout of the seats and interior and exterior rearview mirrors. Value; the specific position value of variable M is determined by the change of the dummy's height and eyeball distance; after the variable M determines the unique value, the specific values ​​of variables X, variable Y, and variable Z are also determined; then the driver's field of view of the inside and outside rearview mirrors is adjusted to the optimal position, and the VCU controls the rearview mirror motor control variable N; for example: the variable M of the unique position corresponding to dummies of different heights and dummies with different eyeballs is adjusted to the optimal position through simulation calibration, thus completing the calibration of the controller's inside and outside rearview mirror motor angle control variable N data packet.

[0095] In actual applications, when adjusting the field of view of the rearview mirror, it can be determined in the following manner. Figure 5 A schematic diagram of the rearview mirror field of view provided by an embodiment of the present invention is shown in FIG. A reference auxiliary line is calibrated on the ground with a length of 50 m. When the vehicle is calibrated, the reference auxiliary line is required to be 100 m away from the rear of the vehicle.

[0096] like Figure 5 As shown, the process of determining the field of view of the endoscope may include:

[0097] A calibration frame is set on the rearview mirror at 1 / 2 of the lower edge, and the height of the calibration frame can be set according to actual needs. For example, the height of the calibration frame can be 10mm. By adjusting the angle of the rearview mirror, the calibration reference auxiliary line behind the vehicle is adjusted to the calibration frame. At the same time, the four corners of the rear windshield of the calibrated vehicle are required to be in the center of the rearview mirror. At this time, the VCU will record the position status signal of the rearview mirror motor. That is, a mapping relationship is established between the distance from the dummy eye to the rearview mirror as variable Y and the rearview mirror motor angle control variable N. Repeat the above calibration operation, and finally record the rearview mirror motor control variables corresponding to each specification of dummy eyes after the optimal field of view calibration into the controller, and the calibration of the second data packet is completed.

[0098] The process of determining the field of view of the left rearview mirror may include:

[0099] A calibration frame is set at 1 / 3 of the distance from the lower edge of the left rearview mirror. The height of the calibration frame can be set according to actual needs. For example, the height of the calibration frame can be 10mm. Another calibration reference auxiliary line is set at 1 / 4 of the distance from the inner edge of the mirror. It should be noted that the inner edge refers to the edge of the left rearview mirror close to the vehicle.

[0100] By adjusting the angle of the left rearview mirror, the calibration reference auxiliary line behind the vehicle is adjusted to the calibration frame, and the outer edge of the left side of the vehicle body is required to fit with another calibration reference auxiliary line; at this time, the VCU will record the position status signal of the interior rearview mirror motor. That is, the mapping relationship between the distance from the dummy eye to the left rearview mirror as variable X and the left rearview mirror motor angle control variable N is established. Repeat the above calibration operation, and finally record the left rearview mirror motor control variables corresponding to the best field of view calibration of each specification of dummy eyes into the controller, and the calibration of the first data packet is completed.

[0101] The field of view determination process of the right rearview mirror may include:

[0102] A calibration frame is set at 1 / 3 of the distance from the lower edge of the right rearview mirror. The height of the calibration frame can be set according to actual needs. For example, the height of the calibration frame can be 10mm. Another calibration reference auxiliary line is set at 1 / 4 of the distance from the inner edge of the mirror. It should be noted that the inner edge refers to the edge of the right rearview mirror close to the vehicle.

[0103] By adjusting the mirror position, the position of the red dotted line directly behind the vehicle is adjusted to the calibration frame, and the outer edge of the right side of the vehicle body is required to fit with another calibration reference auxiliary line; at this time, the VCU will record the position status signal of the interior rearview mirror motor. That is, the mapping relationship between the distance from the dummy eye to the left rearview mirror as variable X and the left rearview mirror motor angle control variable N is established. Repeat the above calibration operation, and finally record the corresponding right rearview mirror motor control variables after the best field of view calibration of each specification of dummy eyes into the controller, and the calibration of the third data packet is completed.

[0104] In order to avoid the automatic recognition function of the rearview mirror field of view being repeatedly activated due to misidentification of the relative position of the driver's eyes (such as the driver's head rotation), the rearview mirror adjustment method provided by the embodiment of the present invention may further include, after obtaining the driving scene of the vehicle and the driver's eye distance, and before determining the first parameter for adjusting the rearview mirror based on the driver's eye distance:

[0105] Get the driver's head posture;

[0106] If the driver's head posture is in a preset position and the driver's head posture is maintained for more than a preset time, an adjustment instruction for adjusting the rearview mirror is sent.

[0107] The preset position of the driver's head posture can be the middle position of the steering wheel, and the head posture holding time can be 5 seconds. When the above conditions are met, after the driver's intention to adjust the rearview mirror is recognized, the rearview mirror is adjusted according to the first parameter.

[0108] By obtaining the position of the driver's head posture and the time the head posture is maintained, the incorrect adjustment of the rearview mirror caused by the driver's head rotation can be avoided, further improving driving safety.

[0109] In one embodiment, the driving scenario includes a merging scenario, and determining the second parameter for adjusting the rearview mirror based on the driving scenario includes:

[0110] If the driving scene is a merging scene,

[0111] Get the first angle of the left rearview mirror; the first angle is the current angle of the left rearview mirror;

[0112] According to the first angle of the left rearview mirror, a second parameter is determined so that the field of view of the left rearview mirror obtained after adjustment according to the second parameter is greater than the field of view of the first angle of the left rearview mirror.

[0113] In actual applications, the VCU can receive information from the steering wheel angle sensor and the vehicle navigation host, and after determining that the vehicle enters the lane-merging scene, it can adjust the angle of the left rearview mirror in advance according to the second parameter. For example: when the vehicle enters the 30 meters before the high-speed lane-merging entrance, the left rearview mirror on the vehicle will automatically adjust to the left rearview mirror of the vehicle, so that the field of view of the left rearview mirror after adjustment according to the second parameter is greater than the field of view of the first angle of the left rearview mirror, so that the driver can more safely identify the rear vehicle on the main lane of the high-speed lane behind the vehicle, and can make acceleration and deceleration judgments in advance, making vehicle driving safer and more reliable.

[0114] In order to further improve driving safety, the rearview mirror adjustment method provided in this embodiment may also include:

[0115] If the vehicle leaves the merging scene, adjust the left rearview mirror according to the first angle.

[0116] When the vehicle leaves the merging scene and enters the flat road scene, the vehicle adjusts the left rearview mirror according to the first angle. In actual application, the left rearview mirror can be adjusted according to the first angle 2 seconds after the vehicle enters the flat road scene.

[0117] In one embodiment, the driving scene includes a ramp scene, and based on the driving scene, determining the second parameter for adjusting the rearview mirror includes:

[0118] If the driving scene is a ramp scene,

[0119] Get the second angle of the rearview mirror; the second angle is the current angle of the rearview mirror;

[0120] According to the second angle of the rearview mirror, a second parameter is determined so that the field of view of the rearview mirror obtained after adjustment according to the second parameter is larger than the field of view of the current second angle of the rearview mirror.

[0121] In actual applications, the VCU can receive the slope angle of the slope sensor to determine whether the vehicle is in a slope scene. When the vehicle enters uphill and downhill road conditions, there is an upward or downward blind spot in the driver's rearview mirror field of view; at this time, the rearview mirror is adjusted according to the second parameter so that the field of view of the rearview mirror after adjustment according to the second parameter is larger than the field of view of the current rearview mirror second angle, so that the driver can easily observe the surrounding vehicles and improve driving safety.

[0122] In one embodiment, the method further comprises:

[0123] If the vehicle leaves the slope, adjust the rearview mirror according to the second angle.

[0124] When the vehicle leaves the ramp scene and enters the flat road scene, the vehicle adjusts the rearview mirror according to the second angle. In actual application, the rearview mirror can be adjusted according to the second angle 2 seconds after the vehicle enters the flat road scene.
