[0002] The visual range of a car's rearview mirror is fixed; only the area covered by the lens is visible. Blind spots have little impact when the car is driving straight. However, blind spots have a significant impact when the car is changing lanes or turning. To improve driving safety when changing lanes or turning, the existing technology adjusts the angle of the rearview mirror to cover the blind spot whenever the vehicle changes lanes or turns, even if there are no vehicles in the blind spot that need to be avoided. When the vehicle is reversing, the rearview mirror automatically flips down to avoid a collision, regardless of whether there are obstacles in the blind spot. As a result, the rearview mirror in existing cars needs to be adjusted and flipped many times, and adjustments made when there are no vehicles or obstacles in the blind spot are meaningless. However, each adjustment affects the durability of the rearview mirror motor, reducing its service life. Summary of the Invention

[0041] The specific implementation of this application is further described below with reference to the accompanying drawings.

[0042] It is easy to understand that according to the technical solution of this application, a variety of structural methods and implementation methods can be replaced with each other by those skilled in the art without changing the essential spirit of this application. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of this application and should not be regarded as the entire application or as a limitation or restriction of the technical solution of the application.

[0043] This embodiment provides a method for controlling a rearview mirror of an automobile, which is applied to a rearview mirror control subsystem of an automobile or a controller such as a vehicle controller that has a control function and can establish a communication connection with a rearview mirror motor. Figure 1 As shown, the method includes:

[0044] S100: When a driving status signal of a vehicle changing lanes, turning, or reversing is detected, blind spot area information is obtained.

[0045] These monitoring functions are achieved through various sensors installed throughout the vehicle. Examples include cameras distributed around the vehicle, millimeter-wave radars installed near the front and rear bumpers and side mirrors, steering angle sensors on the steering column, wheel speed sensors on the wheels, and lateral acceleration sensors near the vehicle's center of mass. For example, when monitoring turns, the steering angle sensor accurately detects the steering wheel's rotation angle. Different rotation angles correspond to different turning radii. By measuring this angle, the vehicle's control system can determine the vehicle's turning intention and magnitude.

[0046] Blind spot information can be obtained through the car's Blind Spot Detection (BSD) system. BSD can monitor the area behind the vehicle in real time, usually 2-5 meters behind the vehicle and 1-2 meters to the side to see if there are any vehicles entering the blind spot.

[0047] S200: Analyze the blind spot area information to determine whether there is a target object in the blind spot, where the target object includes a motor vehicle, a non-motor vehicle, a pedestrian, and / or an obstacle.

[0048] When the BSD senses a vehicle in the blind spot, its built-in algorithm can automatically determine whether there is a target object such as a vehicle or pedestrian in the blind spot, and can also determine its location. When the BSD senses a vehicle in the blind spot, it will issue a prompt. The prompt logic is shown in Table 1:

[0049] Table 1 BSD induction prompt logic

[0050]

[0051] That is, when the scenario in the above table occurs, it is determined according to the prompt logic whether to issue a prompt message indicating that there is a target object in the blind spot.

[0052] S300: If the target object does not exist in the blind spot, the motor controlling the rearview mirror of the vehicle maintains the current state, that is, the motor does not need to move.

[0053] The solution in the above embodiment acquires blind spot information when detecting a vehicle's lane change, turn, or reverse driving status signal. By analyzing this blind spot information, it is possible to determine whether a target object is within the blind spot. The target object can be a motor vehicle, non-motor vehicle, pedestrian, or other obstacle. If no target object exists within the blind spot, the motor controlling the vehicle's rearview mirror maintains its current state. In other words, when there is no target object within the blind spot, there is no need to adjust the angle of the rearview mirror, and the rearview mirror motor does not need to operate. This prevents pointless reversal of the rearview mirror, reduces unnecessary motor wear, and improves the motor's durability and service life.

[0054] Preferably, if Figure 2 As shown, the method further includes S400: if the target object is within the blind spot, controlling the motor of the vehicle rearview mirror to adjust the rearview mirror angle so that the coverage area of ​​the rearview mirror includes the blind spot. This step is to actively fill the blank field of view in the blind spot, eliminate collision accidents caused by the blind spot, improve driving safety, and enhance user experience. Specifically, the conditions for starting the vehicle rearview mirror flip are shown in Table 2:

[0055] Table 2 Conditions for starting the flip of the rearview mirror

[0056]

[0057] In the table above, a Level 1 alert condition refers to a BSD alert signal, while a Level 2 alert condition refers to a lateral steering command initiated in addition to a BSD alert signal. According to the table above, the rearview mirror will only flip outward if the Level 2 alert condition is met.

[0058] refer to Figure 3 and Figure 4 As shown, no matter the car is driving on the road or reversing in parking or other scenarios, if it can be determined that there is a target object in the blind spot, the rearview mirror will flip to the target position to help the driver understand the situation in the blind spot and avoid the risk of collision.

[0059] In a specific implementation, if a car is driving on a road and needs to change lanes or turn left or right, the flipping of the rearview mirror can be adjusted according to different situations. Specifically, step S400 includes:

[0060] S401: If the target object is within the blind area, adjust the duty cycle of the pulse width modulation signal of the motor to 100%.

[0061] In this solution, the duty cycle of the motor's pulse-width modulation signal affects the mirror's flipping speed. Typically, a car's rearview mirror adjusts at a speed of 3° / s, but the driver's eye moves much faster than this. To match this speed, this solution increases the duty cycle of the pulse-width modulation signal to 100%, achieving a mirror flipping speed of approximately 22° / s, equivalent to the speed of a conventional folded rearview mirror. This high-speed mirror flipping speed meets the human eye's rotational speed requirement.

[0062] S402: Acquire a target position of the rearview mirror, and use the pulse width modulation signal to control the motor to drive the rearview mirror to the target position.

[0063] The target position can be adjusted according to the real-time road conditions of the car. In this scheme, the target position is calculated separately using the driving conditions of highways and non-highways, which enables the rearview mirror control method to be applicable to various road conditions and has high flexibility and adaptability.

[0064] Specifically, if the driving status signal indicates that the vehicle is changing lanes or turning, then:

[0065] S4021: Obtain the vehicle's driving conditions and determine lane widths based on the conditions. If the conditions indicate the vehicle is traveling on a highway, the lane widths are determined according to highway pavement design rules. If the conditions indicate the vehicle is traveling on a non-highway, the non-motorized vehicle lane width within the lane widths is determined according to the maximum non-motorized vehicle lane width.

[0066] The lane widths of expressways and non-expressways vary depending on factors such as road grade, design speed, and traffic volume. Expressway pavement primarily consists of driving lanes, a median (central divider and left curb), hard shoulders, and dirt shoulders. Taking a four-lane, two-way road as an example, the median is generally 3 meters wide, each lane is 3.75 meters wide, the hard shoulders on both sides are 3 meters wide, and the dirt shoulders are 0.75 meters wide. Expressway lanes are generally 3.75 meters wide to meet the requirements of normal vehicle driving and safe spacing, ensuring vehicle stability and safety at high speeds. On sections with lower design speeds (e.g., 60-80 km / h), individual lanes may be 3.5 meters wide. Emergency lanes are generally 3 meters wide and are used for temporary parking in emergencies or for vehicles with breakdowns awaiting rescue. Urban road motor vehicle lanes: For urban roads with a design speed of 60 km / h or more, the lane width is generally 3.75 meters; for roads with a design speed of 40-60 km / h, the lane width is 3.5 meters; and for roads with a design speed of less than 40 km / h, the lane width is 3.25 meters. Urban road non-motor vehicle lanes: The width is generally between 1 and 2.5 meters. The minimum width of a single non-motor vehicle lane is no less than 1 meter. If there are two or more non-motor vehicle lanes, the width of each lane is generally 1.5 meters.

[0067] S4022: Obtain the driver's eye point position and ground line position.

[0068] The eyepoint represents the position of the driver's eyes. In automotive design, the eyepoint's location is typically determined based on ergonomics and statistical data to ensure the driver has a good field of vision. Ground line position refers to the various lines on the ground within the driver's field of view during driving, such as lane markings and stop lines. These lines play an important role in helping the driver determine the vehicle's position, distance, and direction. While driving, the driver can determine whether the vehicle is staying within its lane and whether it needs to adjust its direction by observing the relative position of ground lines and the vehicle body.

[0069] S4023: Determine the target position of the rearview mirror based on the lane width, the driver's eye point position, the ground line position and rearview mirror design rules.

[0070] refer to Figure 5aAssuming that the lane width of a non-highway is 3.5 meters, and based on the worst road conditions, the non-motorized vehicle lane is calculated to be 2.5 meters. Based on the worst conditions, the target electric vehicle size is calculated to be 1.8×0.75 meters. The area in front of the B-pillar can be seen through the window and is not within the blind spot. Based on the driver's eye point, the ground line, and the legal position of the rearview mirror lens, the field of view of the design position can be made according to GB15084 as the green line area shown in the figure. By flipping the rearview mirror to different angles, combining the eye point and the ground line, the field of view of different rearview mirror positions can be calculated according to GB15084. When the rearview mirror is flipped 12 degrees, the field of view extends to the red dotted area, and the field of view can cover all objects in the blind spot. It is preferred that when driving on non-highways, the rearview mirror can be controlled to flip 12 degrees to ensure coverage of the maximum blind spot range.

[0071] refer to Figure 5b In the right lane change scenario on a highway, the lane width is 3.75 meters. Based on the worst-case scenario, the target vehicle dimensions are calculated as 1.844 × 4.4 meters. The area in front of the B-pillar can be seen through the window and is not within the blind spot. The field of view for the design position is determined by the eye point, ground line, and the legal lens position according to GB15084, as shown in the green area. Based on the driver's eye point, ground line, and the legal position of the rearview mirror lens according to GB15084, the field of view for the design position is determined as shown in the green area in the figure. By flipping the rearview mirror to different angles, combining the eye point and ground line, and according to GB15084, the field of view for different rearview mirror positions can be calculated. When the lens is deflected 8 degrees, the field of view extends to the yellow dashed area, covering all objects in the blind spot. In actual application, different rearview mirror flipping conditions can be set according to different scenarios, with the goal of ensuring that the blind spot coverage is achieved.

[0072] The step of obtaining the target position of the rearview mirror further includes, in step S4024, if the driving state signal indicates that the vehicle is reversing, retrieving a pre-stored optimal position of the rearview mirror in the reversing state as the target position of the rearview mirror. That is, when reversing, the rearview mirror flips to a specific position, and the position only needs to be pre-stored and can be directly retrieved when needed.

[0073] In the above solution, the method further includes obtaining the vehicle's speed after the rearview mirror reaches the target position; issuing a warning signal if the speed exceeds a set threshold; and transmitting the rearview mirror monitoring image to the vehicle's display control unit for display on the display. In a specific implementation, if the vehicle changes lanes or turns, the vehicle's speed cannot be too high. The set threshold is typically 40 km / h. If the vehicle changes lanes or turns at too high a speed, the application will issue an alarm to remind the driver to pay attention to driving safety and reduce the risk of collision.

[0074] The rearview mirror system in the above embodiments of the present application is designed to have more complete functions to enhance user experience, such as Figure 6 As shown, it also exchanges information with the vehicle configuration subsystem, power control subsystem, switch subsystem, voice control subsystem, autonomous driving safety assistance subsystem, vehicle deceleration control subsystem, instrument and auxiliary computing subsystem, instrument and auxiliary computing subsystem, electronic control subsystem, and cockpit control subsystem. In specific applications:

[0084] Rearview mirror system: Receives the rearview mirror function configuration status sent by the vehicle configuration subsystem as a judgment condition for function enablement. When the configuration status has this function, the rearview mirror function logic takes effect; when the configuration status does not have this function, the rearview mirror function logic does not take effect; receives the power status sent by the power control subsystem as a judgment condition for function enablement. When the power status is OFF, the rearview mirror function is unavailable; when the power status is Comfort, the rearview mirror function is available; when the power status is ON, the rearview mirror function is available; receives the rearview mirror voice switch input information sent by the voice control subsystem as a judgment condition for function startup. When the voice request status is ON, the rearview mirror function is started; when the voice request status is OFF, the rearview mirror function is turned off; receives the rearview mirror function status sent by the cockpit body function subsystem The rearview mirror soft switch input information is used as the function start-up judgment condition.

When ON is sent, the BSD function is turned on; when OFF is sent, the BSD function is turned off; the steering hard switch state input information sent by the switch subsystem is received as the function start-up judgment condition. When ON is sent, the steering hard switch is in the redial state; when OFF is sent, the steering hard switch is in the non-redial state; the vehicle gear state input information sent by the electronic control subsystem is received as the function start-up judgment condition. The rearview mirror function is only started when the D gear is received;

[0085] The rearview mirror system sends the rearview mirror large screen display and off request input information to the instrument and auxiliary computing subsystem as the function startup judgment condition. When ON is sent, the rearview mirror large screen display function is turned on; when OFF is sent, the rearview mirror large screen display function is turned off.
