[0002] The field of view of a car's rearview mirror is fixed; only the area covered by the lens is visible. When driving straight, blind spots have little impact. However, when changing lanes or turning, blind spots have a significant impact. To improve driving safety when changing lanes or turning, current technology adjusts the rearview mirror angle to cover the blind spot whenever the vehicle changes lanes or turns, even if there are no vehicles to avoid in the blind spot. Furthermore, when reversing, to avoid collisions, the rearview mirror automatically tilts downwards regardless of whether there are obstacles in the blind spot. This results in a very high number of rearview mirror angle adjustments and tilts in current cars. Adjustments made when there are no vehicles or obstacles in the blind spot are meaningless, but each adjustment affects the durability of the rearview mirror motor, reducing its lifespan. Summary of the Invention

[0041] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0042] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0043] This embodiment provides a method for adjusting a car rearview mirror, applicable to a car's rearview mirror control subsystem or a vehicle controller, etc., that has control functions and can establish a communication connection with the rearview mirror motor. Figure 1 As shown, the method includes:

[0044] S100: When a vehicle's driving status signal is detected, such as changing lanes, turning, or reversing, information about the blind spot area is obtained.

[0045] The aforementioned monitoring functions can be achieved through various sensors installed on the vehicle. These include cameras distributed around the vehicle body, millimeter-wave radars installed near the front and rear bumpers and side mirrors, steering angle sensors mounted on the steering column, wheel speed sensors mounted on the wheels, and lateral acceleration sensors installed near the vehicle's center of gravity. Taking cornering as an example, when cornering, the steering angle sensor accurately senses 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 turning radius.

[0046] Blind spot information can be obtained through the vehicle's blind spot detection (BSD) system. BSD can monitor the area behind and to the sides of the vehicle in real time to see if any vehicles have entered the blind spot. This area is typically 2-5 meters behind the vehicle and 1-2 meters to the side.

[0047] S200: Analyze the blind spot area information to determine whether there is a target object in the blind spot, wherein the target object includes motor vehicles, non-motor vehicles, pedestrians and / or obstacles.

[0048] When BSD detects a vehicle in its blind spot, its built-in algorithm can automatically determine whether there are vehicles or pedestrians in the blind spot and pinpoint their locations. BSD will issue a notification when it detects a vehicle in its blind spot; the notification logic is shown in Table 1.

[0049] Table 1 BSD Sensory Prompt Logic

[0050]

[0051] That is, when the scenarios in the table above occur, the prompting logic determines whether to issue a prompt message indicating that there is a target object in the blind spot.

[0052] S300: If the target object is not present in the blind spot, the motor of the car rearview mirror is controlled to maintain its current state, that is, the motor does not need to move.

[0053] The solution in the above embodiments acquires blind spot information when monitoring the vehicle's driving status signals of lane changing, turning, or reversing. By analyzing the blind spot information, it can be determined whether there is a target object in the blind spot. The target object can be a motor vehicle, a non-motor vehicle, a pedestrian, or other obstacles. If there is no target object in the blind spot, the motor of the vehicle's rearview mirror is kept in its current state. That is, when there is no target object in the blind spot, there is no need to adjust the angle of the vehicle's rearview mirror, and the rearview mirror motor does not need to perform any action. This avoids meaningless reversal of the vehicle's rearview mirror, reduces unnecessary wear and tear on the motor, and improves the motor's durability and service life.

[0054] Preferably, such as Figure 2 As shown, the method further includes S400: if the target object is in the blind spot, the motor of the car rearview mirror is controlled to adjust the angle of the rearview mirror so that the coverage area of ​​the rearview mirror covers the blind spot. This step actively fills the blank field of vision in the blind spot, prevents collision accidents caused by blind spots, improves driving safety, and enhances user experience. Specifically, the conditions for initiating the car rearview mirror rotation are shown in Table 2:

[0055] Table 2 Conditions for Activating Car Rearview Mirror Flip-Up

[0056]

[0057] In the table above, a Level 1 warning condition means that the BSD (Battery Detection and Steering) has issued a warning signal, while a Level 2 warning condition means that a side steering command has been activated in addition to the BSD warning signal. According to the table, the side mirror will only fold outwards if the Level 2 warning condition is met.

[0058] refer to Figure 3 and Figure 4 As shown, whether a car is driving on the road or reversing in parking or other scenarios, if a target object can be identified in the blind spot, the rearview mirror can be flipped to the target position to help the driver understand the situation in the blind spot and avoid the risk of collision.

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

[0060] S401: If the target object is in the blind zone, 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 rearview mirror's tilting speed. Normally, a car's rearview mirror adjusts at a speed of 3° / s, but the driver's eye rotation speed is much higher. To match this speed, the duty cycle of the pulse width modulation signal is set to 100%, achieving a tilting speed of approximately 22° / s, equivalent to the tilting speed of a conventional rearview mirror during folding. This high-speed tilting of the rearview mirror meets the demands of the driver's eye rotation speed.

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

[0063] The target position can be adjusted according to the real-time road conditions of the vehicle. In this solution, the target position is calculated separately for highway and non-highway driving conditions, which makes the rearview mirror adjustment method applicable to various road conditions, with 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 road conditions for vehicle travel and determine the lane width based on the road conditions. If the road conditions indicate that the vehicle is traveling on a highway, the lane width is determined according to the highway pavement design rules; if the road conditions indicate that the vehicle is traveling on a non-highway, the width of the non-motorized vehicle lane in the lane width is determined according to the maximum non-motorized vehicle lane width.

[0066] The lane widths of highways and non-highway roads vary depending on factors such as road grade, design speed, and traffic flow. Highway pavement mainly consists of driving lanes, a median strip (central divider and left curb), hard shoulders, and unpaved shoulders. Taking a two-way four-lane highway as an example, the median strip is generally 3 meters wide, each driving lane is 3.75 meters wide, the hard shoulders on both sides are each 3 meters wide, and the unpaved shoulders are each 0.75 meters wide. The driving lane width on highways is generally 3.75 meters to meet the needs of normal vehicle movement and safe following distances, ensuring the stability and safety of vehicles at high speeds. In sections with lower design speeds (such as 60-80 km / h), some driving lanes may be 3.5 meters wide. Emergency lanes are generally 3 meters wide, used for temporary parking of vehicles in emergencies or for vehicles that have broken down and are awaiting assistance. Urban road motor vehicle lanes: For urban roads with a design speed of 60 km / h or higher, the lane width is generally 3.75 meters; for a design speed of 40-60 km / h, the lane width is 3.5 meters; and for a design speed below 40 km / h, the lane width is 3.25 meters. Urban road non-motorized vehicle lanes: The width is generally between 1 and 2.5 meters. The minimum width of a single non-motorized vehicle lane is not less than 1 meter; when there are two or more non-motorized vehicle lanes, each lane is generally 1.5 meters wide.

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

[0068] The eyepoint is the point representing the driver's eye position. In automotive design, the eyepoint's location is typically determined based on ergonomics and statistical data to ensure the driver has good visibility. Ground line positions refer to the various lines on the ground within the driver's field of vision during driving, such as lane lines and stop lines. These lines play a crucial role in the driver's judgment of the vehicle's position, distance, and direction. During driving, the driver can observe the relative position of the ground lines to the vehicle body to determine whether the vehicle is within the lane and whether adjustments to the direction are necessary.

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

[0070] refer to Figure 5aAssuming the width of a non-highway lane is 3.5 meters, and under the worst-case scenario, the non-motorized vehicle lane is 2.5 meters wide. Under the worst-case scenario, the target electric vehicle is estimated to be 1.8 x 0.75 meters. The area in front of the B-pillar is visible through the window and is not within the blind spot. Based on the driver's eye point, ground line, and the legal position of the rearview mirror lens, according to GB15084, the field of vision at the design position is the green area shown in the diagram. By rotating the rearview mirror at different angles, combined with the eye point and ground line, the field of vision at different rearview mirror positions can be calculated according to GB15084. When the rearview mirror is rotated 12 degrees, the field of vision extends to the red dotted line area, covering all objects in the blind spot. Preferably, when driving on non-highways, the rearview mirror can be rotated 12 degrees to ensure maximum coverage of the blind spot.

[0071] refer to Figure 5b The scenario depicts a right lane change on a highway, where the lane width is 3.75 meters. Under the worst-case scenario, the target vehicle's dimensions are calculated to be 1.844 x 4.4 meters. The area in front of the B-pillar is visible through the window and is not within the blind spot. Based on the driver's eye point, ground line, and the legal position of the rearview mirror lens according to GB15084, the designed field of vision is defined as the green area. Using the driver's eye point, ground line, and the legal position of the rearview mirror lens, the designed field of vision is defined as the green area shown in the diagram, according to GB15084. By rotating the rearview mirror at different angles and combining the eye point and ground line, the field of vision for different rearview mirror positions can be calculated according to GB15084. When the lens is rotated 8 degrees, the field of vision extends to the yellow dotted line area, covering all objects in the blind spot. In practical applications, different rearview mirror rotation settings can be configured for different scenarios, aiming to cover the blind spot area.

[0072] The step of obtaining the target position of the rearview mirror further includes S4024: if the driving status signal indicates that the car is reversing, then the optimal position of the rearview mirror in the reversing state is retrieved as the target position of the rearview mirror. That is, when reversing, the rearview mirror flips to a specific position, and it is only necessary to store the position in advance, which can be retrieved directly when needed.

[0073] In the above solution, the method further includes acquiring the vehicle's speed after the rearview mirror reaches the target position; issuing a warning signal if the speed exceeds a set threshold; and sending the rearview mirror monitoring image to the vehicle's display control unit for display on the screen. In specific implementation, if changing lanes or turning, the vehicle speed cannot be too high; the set threshold is typically 40 km / h. If changing lanes or turning at excessive speed, this 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 this application is designed to have more complete functions and improve user experience, such as... Figure 6 As shown, it also interacts 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 calculation subsystem, electronic control subsystem, and cockpit control subsystem. In specific applications:

If ON is received, the rearview mirror screen display function is enabled; if OFF is received, the rearview mirror screen display function is disabled.

[0084] Rearview Mirror System: Receives rearview mirror function configuration status from the vehicle configuration subsystem as a condition for function enable.

When the soft switch is ON, the rearview function is activated; when the soft switch is OFF, the rearview function is deactivated. It also receives vehicle speed information from the vehicle deceleration control subsystem; receives rearview mirror BSD input information from the autonomous driving safety assistance subsystem as a condition for function activation. When ON is sent, the BSD function is enabled; when OFF is sent, the BSD function is disabled; receives steering hard switch status input information from the switch subsystem as a condition for function activation. When ON is sent, the steering hard switch is in a redial state; when OFF is sent, the steering hard switch is in a non-redial state; and receives vehicle gear position status input information from the electronic control subsystem as a condition for function activation. The rearview mirror function is only activated when the vehicle is in Drive (D) gear.

[0085] The rearview mirror system sends input information to the instrument and auxiliary calculation subsystem regarding the display and shutdown of the rearview mirror screen as a function activation condition. When ON is sent, the rearview mirror screen display function is turned on; when OFF is sent, the rearview mirror screen display function is turned off.
