Technical Field
[0001] This invention relates to the field of automotive technology, and in particular to an automotive rearview mirror system and automotive products. Background Technology
[0002] Rearview mirrors installed in cars provide drivers with a view of what's behind the vehicle, expanding their field of vision and allowing them to observe more of the surroundings, thus enabling them to make correct driving decisions. Currently, rearview mirrors based on optical reflectors are widely used, offering advantages such as low cost and clear visibility. However, due to the limited area of a rearview mirror and its fixed installation position, the driver's view of what's behind the car is also limited, not covering the entire area behind the vehicle, thus creating blind spots. While driving in a straight line, blind spots have a relatively small impact on traffic safety. However, during lane changes or other maneuvers, the inability to see vehicles located in the blind spot can lead to failure to maintain appropriate speed and distance, potentially resulting in traffic accidents.
[0003] To address the issue of blind spots, some automobiles employ Blind Spot Detection (BSD) systems, which automatically monitor rear blind spots and issue warnings to the driver when a potential collision risk is detected. However, BSD systems are susceptible to performance degradation due to factors such as rain and fog, and they also require specialized components like millimeter-wave radar, resulting in high usage and maintenance costs. Summary of the Invention

When it is determined that the real-time positioning information is located in the merging zone of the first road, the control module controls the deflection drive module to drive the rearview mirror module based on the roadside distance information. The first road is the road where the car is currently traveling, the first road merges into the second road, and the merging zone is the area in the first road before merging into the second road.

Wherein, the first side is the left side and the second side is the right side, or the first side is the right side and the second side is the left side.
[0007] Further, controlling the deflection drive module to drive the rearview mirror module based on the curb distance information includes: Obtain the orientation information of the second road relative to the first road; When the orientation information is the first side, obtain the second road edge distance information; Based on the second edge distance information, the deflection drive module is controlled to drive the first rearview mirror unit to deflect.
[0008] Further, the step of controlling the deflection drive module to drive the first rearview mirror unit to deflect based on the second path distance information includes: Obtain the deflection angle of the target; Obtain the time series of the second path distance information; Based on the time series, determine the time change rate of the second path distance information; The deflection rate is determined in a positive correlation based on the stated rate of change over time; the deflection rate represents the angle of deflection per unit time. The deflection drive module is controlled to drive the first rearview mirror unit to deflect in the first lateral direction at the deflection rate until the deflection angle reaches the target deflection angle.
[0009] Furthermore, obtaining the deflection target angle includes: The intersection angle between the first road and the second road is obtained by querying the electronic map. The deflection target angle is determined based on the intersection angle.
[0010] Furthermore, the step of controlling the deflection drive module to drive the rearview mirror module based on the curb distance information further includes: Based on the second edge distance information, the deflection drive module is controlled to drive the second rearview mirror unit to deflect.
[0011] Further, the step of controlling the deflection drive module to drive the second rearview mirror unit to deflect based on the second path distance information includes: Set the first, second, and third distance intervals to increase sequentially; When the second path distance information is within the first distance range, the deflection drive module is controlled to drive the second rearview mirror unit to perform synchronous deflection in the same direction as the first rearview mirror unit.

[0015] The beneficial effects of this invention are as follows: The rearview mirror system in the embodiment can control the first rearview mirror unit located on the same side as the second lane into which the car is about to merge, to deflect towards the direction of the second lane. This causes the driver's field of vision behind the car observed through the first rearview mirror unit to shift towards the direction of the second lane. As a result, the driver can obtain the rear view of the car in the direction of the second lane even when the car is still in the first lane and has not yet merged into the second lane. This allows the driver to see the traffic conditions in the second lane into which the car is about to merge, reducing the area of the blind spot in the second lane into which the car is about to merge. This is beneficial for the driver to observe while driving, make correct driving decisions, and ensure traffic safety. Attached Figure Description

Detailed Implementation
[0017] This embodiment provides a car rearview mirror system. (Refer to...) Figure 1 The automotive rearview mirror system includes a control module, a positioning module, a rearview mirror module composed of a first rearview mirror unit and a second rearview mirror unit, a deflection drive module composed of a first deflection drive unit and a second deflection drive unit, and a distance detection module composed of a first distance detection unit and a second distance detection unit.
[0018] In this embodiment, a component with data acquisition, processing, output, and control functions can be used as the control module. A satellite positioning unit based on GPS or BeiDou can be used as the positioning module. The positioning module can perform real-time vehicle positioning, obtaining real-time positioning information including longitude and latitude. The positioning module can also load offline or online electronic maps, query the corresponding location on the electronic map based on the real-time positioning information, thereby determining the vehicle's position on the electronic map, as well as information such as roads and buildings near the vehicle's location.
[0019] In this embodiment, the first side is the left side when viewed from the rear to the front of the car, and the second side is the right side, as an example. Since cars are symmetrical, the technical approach when the first side is the right side and the second side is the left side is easy to understand.
[0020] Specifically, both the first and second rearview mirror units are optical reflectors. Taking the first rearview mirror unit as an example, as... Figure 2 As shown, it is installed on the first side of the car body, i.e., the left side. Specifically, a hinge or other structure can be used to mount the first rearview mirror unit to the car body, making the angle between the first rearview mirror unit and the straight line in the front-rear direction of the car body adjustable. (Refer to...) Figure 2 When the first rearview mirror unit is in its initial position, it forms an angle of magnitude θ0 with the straight line connecting the front and rear of the vehicle. Through the reflection of the first rearview mirror unit, light from behind the car is reflected into the driver's eyes, providing the driver with a view to the left rear of the car. Based on the same principle, the second rearview mirror unit provides the driver with a view to the right rear of the car.
[0021] In this embodiment, the first deflection drive unit and the second deflection drive unit each include components such as motors, as shown in the reference. Figure 1 The first deflection drive unit is used to drive the first rearview mirror unit to deflect or reset in the horizontal direction, and the second deflection drive unit is used to drive the second rearview mirror unit to deflect or reset in the horizontal direction. Taking the first deflection drive unit and the first rearview mirror unit as an example, refer to... Figure 2 The first deflection drive unit can drive the second rearview mirror unit to deflect relative to the vehicle body to the first side, i.e., the left side. For example, during one deflection process, the first deflection drive unit drives the first rearview mirror unit to deflect relative to its initial position to the first side, i.e., the left side, by an angle of Δθ, so that after deflection, the first rearview mirror unit forms an angle of θ0 + Δθ with the straight line of the vehicle body in the longitudinal direction. The first deflection drive unit can also drive the first rearview mirror unit to deflect relative to the vehicle body to the second side, i.e., the right side, so that the first rearview mirror unit returns to its original position, i.e., the angle between the first rearview mirror unit and the vehicle body decreases.
[0022] In this embodiment, both the first deflection drive unit and the second deflection drive unit are controlled by the control module. Specifically, the control module can control the starting, stopping, deflection direction, deflection rate, and other operating parameters of the first and second deflection drive units.
[0023] In this embodiment, the first distance detection unit and the second distance detection unit each include components such as ultrasonic radar. (Refer to...) Figure 3 Taking the second distance detection unit as an example, the second distance detection unit is installed on the second side of the vehicle body, i.e., the right side. The second distance detection unit emits ultrasonic waves outward in a direction perpendicular to the straight line connecting the front and rear distances of the vehicle body. When the ultrasonic waves encounter a curb obstacle (such as a guardrail or tree) on the second side, they are reflected back to the second distance detection unit. The second distance detection unit calculates the distance between itself and the curb obstacle on the second side, i.e., the right side, by calculating the sound wave's flight time, i.e., the second curb distance information d. right Based on the same principle, the first distance detection unit can detect the distance between the vehicle body and the curb obstacle on the first side, i.e., the first curb distance information d. left .
[0024] Other principles can also be used to implement the first and second distance detection units. For example, taking the second distance detection unit as an example, a camera with visual detection capabilities can be used as the second distance detection unit. The camera captures an image of the second side of the vehicle, i.e., the right side, thereby obtaining an image including roadside obstacles (such as guardrails, trees, etc.) on the second side. The second distance detection unit performs visual detection on the image to extract the depth information of the roadside obstacles in the image, thereby obtaining the second roadside distance information d. right .
[0025] In this embodiment, based on Figure 1 The structure shown allows the control module to execute the control method for the automotive rearview mirror system. (Refer to...) Figure 4 The control method for a car rearview mirror system includes the following steps: S1. Perform real-time queries on electronic maps based on real-time location information; S2. Detect whether the real-time location information is located in the merging area of the first road; S3. When it is determined that the real-time location information is located in the merging area of the first road, check whether a trigger command has been received; S4. Once the trigger command is confirmed, the deflection drive module is controlled to drive the rearview mirror module based on the curb distance information.
[0026] In step S1, the control module calls the positioning module to perform a real-time query on the electronic map based on the real-time positioning information, thereby determining the vehicle's own location and the traffic environment near the location.
[0027] In this embodiment, refer to Figure 5 The real-time location information indicates that the car is currently on the first road. Furthermore, based on a query of the electronic map, it is determined that the first road will be merged into the second road. In this embodiment, the control module can determine a distance threshold (e.g., 100m or 300m) and define the area within the first road that is within the distance threshold before the intersection of the first and second roads as the merging zone.
[0028] In step S2, the control module checks the electronic map based on the latest detected real-time location information to determine if the location is within the merging zone of the first road. When this occurs... Figure 5 If the real-time location information indicates that the car is located in the merging zone of the first road, then step S3 is executed.
[0029] In this embodiment, step S3 is an optional step, meaning that step S4 can be executed directly without executing step S3. When step S3 is executed, the control module can detect the trigger command sent by the trigger module. If the trigger command is detected, the control module executes step S4; if the trigger command is not detected, the control module does not execute step S4.
[0030] For example, in this embodiment, the turn signal module can be used as the trigger module. When the driver performs a user operation on the turn signal module, such as turning on the left turn signal, the turn signal module generates a trigger command and sends the trigger command to the control module, thereby triggering the control module to execute step S4.
[0031] In this embodiment, when the control module executes step S4, which is to control the deflection drive module to drive the rearview mirror module based on the curb distance information, the following steps can be performed: S401. Obtain the orientation information of the second road relative to the first road; S402. When the orientation information is the first side, obtain the distance information of the second road edge; S403. Based on the second road edge distance information, control the deflection drive module to drive the first rearview mirror unit to deflect.
[0032] In step S401, the control module can query the location information of the second road relative to the first road by calling an electronic map. The location information indicates whether the second road is located on the first side or the second side relative to the first road. In this embodiment, refer to... Figure 5 Let's take the example of the second road being located on the first side (i.e., on the left) relative to the first road, using directional information.
[0033] In step S402, the control module calls the distance detection unit on the opposite side to the side indicated by the orientation information to perform detection. For example, in this embodiment, the orientation information is the first side, i.e., the left side, so the control module calls the second distance detection unit located on the second side of the vehicle body, i.e., the right side, to obtain the second roadside distance information d. right .
[0034] In this embodiment, when the control module executes step S403, which is to control the deflection drive module to drive the first rearview mirror unit to deflect based on the second edge distance information, the control module can specifically perform the following steps: S40301. Obtain the deflection angle of the target; S40302. Obtain the time series of the second path distance information; S40303. Determine the time change rate of the second path distance information based on the time series; S40304. Determine the deflection rate based on the rate of change over time in a positive correlation; S40305. Control the deflection drive module to drive the first rearview mirror unit to deflect in the first lateral direction at a deflection rate until the deflection angle reaches the target deflection angle.
[0035] In step S40301, as follows Figure 5 As shown, the control module can query the intersection angle Δθ' of the first road and the second road in the electronic map, and use it as the deflection target angle.
[0036] In step S40302, the control module can be at t0, t1, t2...t n-1 t n The second distance detection unit is invoked at multiple sampling times, and the second path distance information detected at sampling time t0 is d. right_0 The distance information of the second path edge detected at sampling time t1 is d. right_1 The distance information of the second path edge detected at sampling time t2 is d. right_2 ...at sampling time t n-1 The detected second path distance information is d right_n-1 At sampling time t n The detected second path distance information is d right_n Thus, the time series d of the second path distance information is obtained. right_0 d right_1 d right_2 ...d right_n-1 d right_n .
[0037] In step S40303, the control module can, for any sampling time, calculate the difference between the second path distance information detected at this sampling time and the second path distance information detected at the previous sampling time, divide it by the duration between two adjacent sampling times, and thus obtain the time change rate corresponding to this sampling time. For example, sampling time t n The corresponding rate of change over time r n =(d right_n -d right_n-1 ) / (t n -t n-1 ) In step S40304, the control module can set a positive coefficient k1, according to the formula... v n =k1|r n | The sampling time t was calculated. n The corresponding deflection rate v n Deflection rate v n This represents the angle of deflection per unit time (e.g., per second). In this embodiment, the deflection rate v n The rate of change of time r at the same time n Positive correlation means that if a car approaches or moves away from the curb on the opposite side of the second road more quickly after entering the merging zone of the first road, then a faster yaw speed will be set, and a slower yaw speed will be set if the car approaches or moves away from the curb on the opposite side of the second road more slowly.
[0038] In step S40305, the control module uses the deflection target angle Δθ' set in step S40301 as the target and controls the first deflection drive unit to drive the first rearview mirror unit at the current deflection rate v. n Deflect to the first side, i.e., to the left, if at t n After the deflection is completed, the deflection angle of the first rearview mirror unit reaches the target deflection angle Δθ' (i.e., the angle between the first rearview mirror unit and the vehicle body reaches θ0 + Δθ'), then the control module controls the first deflection drive unit to stop driving; if at t n If, after a certain moment of deflection, the deflection angle of the first rearview mirror unit does not reach the target deflection angle Δθ' (i.e., the angle between the first rearview mirror unit and the vehicle body does not reach θ0 + Δθ'), then the control module will acquire a new deflection rate v at the next moment. n+1 Continue to control the first deflection drive unit to drive the first rearview mirror unit at a deflection rate v n+1 The mirror is deflected to the first side, i.e., to the left, until the deflection angle of the first rearview mirror unit reaches the target deflection angle Δθ' (i.e., the angle between the first rearview mirror unit and the vehicle body reaches θ0+Δθ').
[0039] In this embodiment, by executing steps S401-S403, the first rearview mirror unit located on the same side as the second lane into which the car is about to merge can be controlled to deflect towards the direction of the second lane. This causes the driver's view of the rear of the car observed through the first rearview mirror unit to shift towards the direction of the second lane. As a result, the driver can obtain the rear view of the car in the direction of the second lane even when the car is still in the first lane and has not yet merged into the second lane, allowing the driver to see the traffic conditions in the second lane into which the car is about to merge. Compared with the technology where the first rearview mirror unit cannot deflect, resulting in the second lane into which the car is about to merge being completely a blind spot, by executing steps S401-S403, the area of the blind spot in the second lane into which the car is about to merge is reduced, which is beneficial for the driver to observe while driving, make correct driving decisions, and ensure traffic safety.
[0040] Specifically, by executing steps S40301-S40305, the distance between the car and the curb on the opposite side of the second lane to which the car is about to merge (i.e., the distance information of the second curb) can be detected. Based on the time change rate of this distance, the approach speed between the car and the second lane to which the car is about to merge can be determined. The faster the approach speed, the faster the first rearview mirror unit deflects, ultimately reaching the deflection target angle. This ensures that the deflection rate of the first rearview mirror unit matches the speed at which the car merges into the second lane, allowing the driver to obtain a timely rear view of the second lane, ensuring correct driving decisions and traffic safety. By setting the deflection target angle to the intersection angle of the first and second lanes, after the first rearview mirror unit deflects, the driver can obtain a rear view equivalent to that obtained when the car has entered the second lane (without the first rearview mirror unit deflecting) while the car is still in the first lane. This allows the driver to obtain a field of vision that is adapted to their habits, which is beneficial for the driver to observe while driving, make correct driving decisions, and ensure traffic safety.
[0041] In this embodiment, when the control module executes step S4, which is to control the deflection drive module to drive the rearview mirror module based on the curb distance information, it can also execute the following steps in addition to executing steps S401-S403: S404. Based on the second road edge distance information, control the deflection drive module to drive the second rearview mirror unit to deflect.
[0042] Specifically, steps S401-S403 are steps for controlling the deflection of the first rearview mirror unit located on the same side as the second lane, and step S404 is a step for controlling the deflection of the second rearview mirror unit located on the opposite side of the second lane. When the control module executes step S404, it can specifically perform the following steps: S40401. Set the first distance interval, the second distance interval, and the third distance interval to increase sequentially; S40402. When the second road distance information is within the first distance range, control the deflection drive module to drive the second rearview mirror unit to perform synchronous deflection in the same direction as the first rearview mirror unit; S40403. When the second road distance information is within the second distance range, control the deflection drive module not to drive the second rearview mirror unit to deflect; S40404. When the second road distance information is within the third distance range, control the deflection drive module to drive the second rearview mirror unit to perform synchronous deflection in the opposite direction to the first rearview mirror unit.
[0043] In step S40401, the control module can set distance thresholds such as d1 (e.g., 0), d2 (e.g., 2m), and d3 (e.g., 4m), and satisfy d1 < d2 < d3, thereby forming a first distance interval [d1, d2), a second distance interval [d2, d3), and a third distance interval [d3, ∞) that increase sequentially.
[0044] By executing step S40401 to set the first distance interval [d1, d2), the second distance interval [d2, d3), and the third distance interval [d3, ∞), it can be determined whether a distance value is small, medium, or large. For example, if a distance value is within the first distance interval [d1, d2), it is determined that the distance value is small; if a distance value is within the second distance interval [d2, d3), it is determined that the distance value is medium; and if a distance value is within the third distance interval [d3, ∞), it is determined that the distance value is large.
[0045] For the newly detected second road edge distance information d in step S40302 right_n (can be denoted as d) right The control module determines its size to determine the steps to be executed. Specifically, if the distance information d along the second path... right The second roadside distance information d is located within the first distance interval [d1, d2). right If the distance information d along the second path is relatively small, then the control module executes step S40402; if the distance information d along the second path is relatively small... right The second distance interval [d2, d3) contains the second roadside distance information d. right If the distance information d is medium, then the control module executes step S40403; if the distance information d of the second path is medium. right Within the third distance interval [d3, ∞), i.e., the second path distance information d right If the value is large, then the control module executes step S40404.
[0046] If the control module executes step S40402, in addition to executing steps S401-S403 to drive the first rearview mirror unit located on the same side as the second lane to deflect to the first side, the control module also drives the second rearview mirror unit located on the opposite side of the second lane to deflect synchronously in the same direction as the first rearview mirror unit. Specifically, refer to... Figure 6 The control module controls the second deflection drive unit to drive the second rearview mirror unit to also deflect to the first side, i.e., the left side, and the deflection of the second rearview mirror unit is synchronized with that of the first rearview mirror unit, for example... Figure 6 In the above, if the deflection angle of the first rearview mirror unit is Δθ at any given time, then the deflection angle of the second rearview mirror unit is also Δθ at the same time.
[0047] If the control module executes step S40403, based on the execution of steps S401-S403, the control module does not control the second deflection drive unit to drive the second rearview mirror unit, so that the second rearview mirror unit does not deflect, for example, so that the angle between the second rearview mirror unit and the vehicle body is maintained at θ0 corresponding to the initial position.
[0048] If the control module executes step S40404, in addition to executing steps S401-S403 to drive the first rearview mirror unit located on the same side as the second lane to deflect to the first side, the control module also drives the second rearview mirror unit located on the opposite side of the second lane to perform a synchronous deflection in the opposite direction to the first rearview mirror unit. Specifically, refer to... Figure 7 The control module controls the second deflection drive unit to drive the second rearview mirror unit to deflect to the opposite side, i.e., the right side, and the deflection of the second rearview mirror unit is synchronized with that of the first rearview mirror unit, for example... Figure 7 In the above, if the deflection angle of the first rearview mirror unit is Δθ at any given time, then the deflection angle of the second rearview mirror unit is also Δθ at the same time.
[0049] In this embodiment, the principle of executing steps S40401-S40404 is as follows: when the second path distance information d right The second roadside distance information d is located within the first distance interval [d1, d2). right A smaller distance indicates that the car is closer to the curb on the opposite side of the second lane during its merging into the second lane. This means that the potential for following vehicles on the opposite side of the second lane is relatively simple. By executing step S40402, driving the second rearview mirror unit to synchronously deflect in the same direction as the first rearview mirror unit can reduce the rearward field of view provided by the second rearview mirror unit on the opposite side of the second lane, thereby prompting the driver to focus on the rearward field of view provided by the first rearview mirror unit on the same side of the second lane. When the distance information d of the second curb is... right The second distance interval [d2, d3) contains the second roadside distance information d.right If the distance is moderate, it means that the distance to the curb on the opposite side of the second lane is moderate during the car's merging into the second lane. This indicates a moderate level of complexity regarding potential following vehicles on the opposite side of the second lane. By executing step S40403 to keep the second rearview mirror unit from deflecting, the rearward field of view provided by the second rearview mirror unit on the opposite side of the second lane can be maintained. This allows the driver to focus on both the rearward field of view provided by the first rearview mirror unit on the same side as the second lane and the rearward field of view provided by the second rearview mirror unit on the opposite side of the second lane. When the second curb distance information d... right Within the third distance interval [d3, ∞), i.e., the second path distance information d right A larger distance indicates that the car is far from the curb on the opposite side of the second lane when merging into the second lane. This means that the situation of vehicles behind the car on the opposite side of the second lane (such as overtaking) is complex. By executing step S40404, the second rearview mirror unit is driven to make a synchronous deflection in the opposite direction of the first rearview mirror unit. This expands the rear view provided by the second rearview mirror unit on the opposite side of the second lane. As a result, when merging into the first lane (i.e., the left), the driver can not only focus on the rear view provided by the first rearview mirror unit on the same side as the second lane, but also obtain a wider rear view provided by the second rearview mirror unit on the opposite side of the second lane, thus dealing with the complex traffic conditions on the other side. Therefore, by executing steps S40401-S40404, the first and second rearview mirror units located on both sides of the vehicle can adapt to the following vehicle conditions encountered when merging into the second lane. Based on the complexity of the following vehicle conditions, they automatically provide the driver with a suitable field of vision, allowing the driver to prioritize the field of vision on the more complex side. This ensures the driver's flexibility in vision during the merging process, which is beneficial for the driver to observe the vehicle, make correct driving decisions, and ensure traffic safety.
[0050] In this embodiment, after detecting that the real-time positioning information is located in the second lane, the control module can control the deflection drive module to drive the rearview mirror module to reset.
