Description

Technical Field

[0001] This application relates to the field of intelligent driving, and more specifically, to display methods, devices, vehicles, and storage media for electronic exterior rearview mirrors in the field of intelligent driving. Background Technology

[0002] Electronic exterior rearview mirrors can achieve functions such as identifying blind spots, navigation, and displaying vehicle status. The electronic exterior rearview mirror controller is connected to the dedicated on-board sensors via an axis, thereby controlling the electronic exterior rearview mirror display to show the image corresponding to the sensor data collected by the on-board sensors.

[0003] In related technologies, the methods employed are as follows: 1. Connecting two cameras to the same controller via coaxial cables, with one controller driving the left and right displays for image display. 2. Connecting two cameras to two separate controllers via coaxial cables, with each controller driving the left and right displays to show the corresponding camera's image.

[0004] However, in related technologies, regardless of the method, it is necessary to configure a separate controller and camera for the electronic exterior rearview mirror. The system architecture of the electronic exterior rearview mirror is complex and redundant, resulting in low utilization of vehicle components. It is difficult to maximize the integration of the electronic exterior rearview mirror system with the vehicle's sensors, which reduces the utilization of vehicle resources and makes the vehicle structure more complex and costly, which urgently needs to be solved. Summary of the Invention

[0005] This application provides a display method, device, vehicle, and storage medium for an electronic exterior rearview mirror. The method can send environmental information corresponding to the vehicle's relative position to the electronic exterior rearview mirror via a corresponding transmission path when the vehicle is in a congested road section, or directly send it to the electronic exterior rearview mirror when the vehicle is not in a congested road section, thereby providing data support for the display of the electronic exterior rearview mirror, realizing intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying vehicle architecture.

[0006] In a first aspect, a display method for an electronic exterior rearview mirror is provided, applied to an intelligent driving controller of a vehicle, the vehicle comprising: sensors included in an intelligent driving system, the sensors being connected to a data transmission unit, the data transmission unit being connected to the intelligent driving controller; the data transmission unit also being connected to an electronic exterior rearview mirror controller; the electronic exterior rearview mirror controller being connected to at least one electronic exterior rearview mirror; the method comprising:

[0007] Identify congested road sections in the vehicle's current driving route that meet preset congestion conditions, and determine whether the vehicle is in the congested road section based on the vehicle's location;

[0008] If the vehicle is in the congested section, the relative position of the vehicle and the congested section is monitored, and the transmission path of the environmental information corresponding to the relative position is controlled according to the relative position, so that the environmental information is transmitted to the electronic rearview mirror for display according to the transmission path; wherein, the environmental information is collected by the sensor;

[0009] If the vehicle is not in the congested area, the data transmission unit is controlled to directly transmit the environmental information collected by the left and right rearview cameras to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror; the left and right rearview cameras are one of the sensors included in the intelligent driving system.

[0010] The above technical solution enables the determination of whether a vehicle is in a congested area based on its location, providing support for subsequent data transmission processing and display according to different road conditions, and realizing intelligent interaction between the electronic rearview mirror and the environment. When the vehicle is in a congested area, the environmental information corresponding to the vehicle's position relative to the road segment is sent to the electronic rearview mirror via the appropriate transmission path; or when the vehicle is not in a congested area, the information is sent directly to the electronic rearview mirror, thereby providing data support for the electronic rearview mirror display, further realizing intelligent interaction between the electronic rearview mirror and the environment, improving the reusability and practicality of vehicle components, reducing vehicle costs, and simplifying vehicle architecture.

[0011] In conjunction with the first aspect, in some possible implementations, controlling the transmission path of environmental information corresponding to the relative position based on the relative position includes:

[0012] Based on the relative position, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror;

[0013] Alternatively, based on the relative position, after receiving the environmental information through the data transmission unit, the environmental information is processed, and the processing result is sent to the data transmission unit so that the processing result can be sent to the electronic rearview mirror through the data transmission unit.

[0014] The above technical solutions enable the transmission of control signals to the data transmission unit based on relative position, thereby displaying environmental information in real time on the electronic rearview mirror and helping users obtain the corresponding external environment when the vehicle is in a congested road section. Alternatively, in this embodiment, the environmental information can be received by the data transmission unit based on relative position, processed, and the information corresponding to the relative position can be extracted to obtain the processing result, thereby improving the intelligence of the vehicle. This eliminates the need for separate sensors on the electronic rearview mirror, increases the device reuse rate, and reduces the requirements for the electronic rearview mirror controller, thus reducing the implementation difficulty.

[0015] In conjunction with the first aspect and the above implementation methods, in some possible implementations, the step of sending a control signal to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror includes:

[0016] When the relative position is the approach position where the road segment is in front of the vehicle and the distance between the vehicle and the road segment is less than a first preset threshold, it is determined whether there is a moving target object behind the side of the vehicle.

[0017] If the target object is present, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller.

[0018] The above technical solution enables the transmission of control signals to the data transmission unit when a target object is present. This control unit then transmits the environmental information collected by the vehicle's left and right rearview cameras sequentially to the electronic rearview mirror via the data transmission unit and the electronic rearview mirror controller. This eliminates the need for processing by the intelligent driving controller, providing data support for the electronic rearview mirror display and further enabling intelligent interaction between the electronic rearview mirror and the environment.

[0019] In conjunction with the first aspect and the above implementation methods, in some possible implementation methods, the step of sending a control signal to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror further includes:

[0020] If the target object does not exist, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right front-view cameras of the vehicle to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller; the left and right front-view cameras are one of the sensors included in the intelligent driving system.

[0021] The above technical solution enables the transmission of control signals to the data transmission unit when the target object is not present. This control unit then transmits the environmental information collected by the left and right front-view cameras of the vehicle to the electronic rearview mirror via the data transmission unit and the electronic rearview mirror controller. This achieves intelligent interaction between the electronic rearview mirror and the environment, reduces vehicle costs, and simplifies the vehicle architecture.

[0022] In conjunction with the first aspect and the above implementation methods, in some possible implementations, the step of sending a control signal to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror includes:

[0023] When the relative position is located in the congested road section, after receiving the environmental information collected by the vehicle's left and right surround view cameras through the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic rearview mirror sequentially through the intelligent driving controller, the data transmission unit, and the electronic rearview mirror through the data transmission unit; the left and right surround view cameras are one of the sensors included in the intelligent driving system.

[0024] With the above technical solution, when the vehicle is located in a congested road section, it can receive environmental information collected by the left and right surround view cameras through the data transmission unit, process the environmental information, and send the processing results to the electronic rearview mirrors in sequence through the intelligent driving controller, the data transmission unit, and the electronic rearview mirrors to control at least one electronic rearview mirror to display the surround view camera data, thereby displaying the relevant image or information of the target object.

[0025] In conjunction with the first aspect and the above implementation methods, in some possible implementations, the step of sending a control signal to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror includes:

[0026] When the relative position is such that the congested road segment is behind the vehicle and the distance between the vehicle and the congested road segment is greater than a second preset threshold and the vehicle is about to move away from the congested road segment, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller; the left and right rearview cameras are one of the sensors included in the intelligent driving system.

[0027] Through the above technical solution, when the congested road section is located behind the vehicle and the distance between the vehicle and the congested road section is greater than the second preset threshold and the vehicle is about to move away from the congested road section, a control signal is sent to the data transmission unit. This control unit then sends the environmental information collected by the vehicle's left and right rearview cameras to the electronic rearview mirror through the data transmission unit and the electronic rearview mirror controller, thereby further realizing the intelligent interaction between the electronic rearview mirror and the environment.

[0029] Obtain the navigation information of the vehicle;

[0030] The relative position is determined based on the navigation information and the location.

[0031] The above technical solution can obtain the vehicle's navigation information and determine the relative position based on the navigation information and location, thereby ensuring the acquisition of the vehicle's specific location information, providing support for judging whether the vehicle is driving in a congested environment, improving the vehicle's intelligence, enhancing the user experience, and reducing the efficiency of vehicle resource utilization.

[0064] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0065] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0066] Traditional rearview mirrors reflect the road surface and surrounding scenery, providing only limited, one-way information and creating blind spots that can easily lead to traffic accidents. To improve this, rearview mirror designs are increasingly using cameras instead of mirrors to capture the vehicle's surroundings and display the information on a screen inside the driver's cabin, such as... Figure 1 As shown, the driver can directly see the images captured by the camera and perceive the environment in real time.

[0067] Regarding existing electronic exterior rearview mirrors (Camera Monitor System, CMS), firstly, as... Figure 2-3 As shown, Figure 2 The two cameras in the center are connected via a coaxial cable to an electronic exterior rearview mirror controller. This controller drives the displays of the left and right electronic exterior rearview mirrors to show the images. Figure 3 The two cameras are connected to the two electronic rearview mirror controllers via coaxial cables. The two electronic rearview mirror controllers drive the left and right electronic rearview mirror displays to display images.

[0068] Secondly, because electronic side mirrors only have a single-sided view, many blind spots cannot be identified. To solve this problem, such as... Figure 4 As shown, rearview mirrors are usually equipped with no fewer than eight visible light cameras to collect environmental information simultaneously in the four directions of the vehicle: front, rear, left, and right.

[0069] Therefore, electronic exterior rearview mirrors in related technologies all require a separate controller and camera, resulting in a complex and redundant system architecture, low utilization of vehicle components, difficulty in maximizing the integration of the electronic exterior rearview mirror system with vehicle sensors, reduced utilization of vehicle resources, and more complex and costly vehicle structures.

[0070] The application scenarios or system architecture of the embodiments of this application will be described next. See also Figure 5The vehicle includes an intelligent driving system 10 and an electronic exterior rearview system 20. The intelligent driving system 10 includes a sensor 11, a data transmission unit 12, and an intelligent driving controller 13. The electronic exterior rearview system 20, unlike electronic exterior rearview mirrors in related technologies, only has an electronic exterior rearview mirror controller 21 and an electronic exterior rearview mirror 22. The sensor 11 is used to collect environmental information, and the data transmission unit 12 is used to send the environmental information from the sensor 11 to the intelligent driving controller 13 and the electronic exterior rearview mirror controller 21. In addition to executing the corresponding intelligent driving control strategy based on the environmental information collected by the sensor 11, the intelligent driving controller 13 can also control the data transmission unit 12 to directly send the environmental information collected by the sensor 11, or send the environmental information processed by the intelligent driving controller 13 to the electronic exterior rearview mirror controller 21. Thus, the electronic exterior rearview mirror controller 21 processes the information so that the electronic exterior rearview mirror 22 can display the corresponding information.

[0071] As one possible way to achieve this, such as Figure 6 As shown, sensor 11 may include, but is not limited to, a side-view camera 111 and a surround-view camera 112. The side-view camera 111 may include, but is not limited to, a front-view side camera and a rear-view side camera, thereby collecting corresponding front-view side camera information, rear-view side camera information, etc., as environmental information.

[0072] In addition, as one possible way to achieve this, such as Figure 6 As shown, in addition to the corresponding sensor 11, the camera also includes a corresponding serializer to serialize the information. The data transmission unit 12 includes a corresponding deserializer and serializer (as shown in deserializer 121, deserializer 123 and serializer 122 in the figure) to deserialize the information collected by the sensor 11. The serializer 122 serializes the information sent by the deserializer 121 or the information sent by the intelligent driving controller 13 and sends it to the deserializer 23 of the electronic exterior rearview system 20 for deserialization. Finally, the electronic exterior rearview mirror controller 21 controls the electronic exterior rearview mirror 22 to display the deserialized information.

[0073] The transmission path can be, but is not limited to, two types of paths:

[0074] Transmission Path 1: Environmental information is collected and serially processed by the side-view camera 111 of sensor 11, and then transmitted to the deserializer 121 of data transmission unit 12 via the signal transmission line. The deserializer 121 of data transmission unit 12 deserializes the data and sends it to the serializer 122 of data transmission unit 12. After receiving the control signal of the transmission instruction from intelligent driving controller 13, the serializer 122 sends it to the electronic exterior rearview mirror 22. That is, by using a bypass link, the data is bypassed by intelligent driving controller 13, thus improving display efficiency and timeliness.

[0075] Transmission path 2: Environmental information is collected and serially processed by the surround-view camera 112 of sensor 11, and then transmitted to the deserializer 123 of data transmission unit 12 via signal transmission line. The deserializer 123 of data transmission unit 12 deserializes the data and sends it to intelligent driving controller 13. Intelligent driving controller 13 sends the result obtained from information processing to serializer 122, which then sends it to electronic exterior rearview mirror 22. That is, by using SOC link, there is no need for bypass link interface, no need to add additional serializer, and the display cost is reduced.

[0076] In summary, given that the data transmission unit 12 of the intelligent driving system 10 has a serializer 122 and the serializer 122 has only one bypass interface, there is only one bypass link. To ensure data timeliness without changing the architecture, this embodiment can choose to transmit side-view related environmental information in many application scenarios through the bypass link. In particular, considering that electronic exterior rearview mirrors mainly replace physical exterior rearview mirrors, the field of view is mainly for long distances behind the vehicle, and the side-view field of view is the most similar. At the same time, the bypass link is fast and can meet the timeliness requirements. If the surround-view related environmental information is also transmitted through the bypass link, an additional serializer is required, which increases the cost. Therefore, it is possible to use the SOC link to transmit the surround-view related environmental information to reduce costs and simplify the architecture. However, there are many possible implementation methods. For example, the surround-view related environmental information can be transmitted through the SOC link, while the side-view related environmental information can be transmitted through the bypass link. The specific method can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[0077] Figure 7 This is a schematic flowchart illustrating a display method for an electronic exterior rearview mirror provided in an embodiment of this application.

[0078] For example, such as Figure 7 As shown, the method includes the following steps:

[0079] In step S701, congested road sections that meet preset congestion conditions are identified in the vehicle's current driving route, and the vehicle's location is used to determine whether the vehicle is in a congested road section.

[0080] It is understood that the embodiments of this application can use the vehicle controller to provide traffic information from the navigation function to determine the congestion situation of the current road segment where the vehicle is located; the vehicle's location in the embodiments of this application can be obtained through GNSS (Global Navigation Satellite System).

[0081] In actual implementation, the embodiments of this application can identify congested road sections in the current driving road that meet certain congestion conditions. For example, it can use GNSS to determine whether the vehicle is in a congested road section based on the vehicle's location, thereby providing support for subsequent data transmission processing and display based on different road conditions, realizing intelligent interaction between the electronic rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture.

[0082] It should be noted that the preset congestion conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0083] In step S702, if the vehicle is in a congested section, the relative position of the vehicle and the congested section is monitored, and the transmission path of the environmental information corresponding to the relative position is controlled according to the relative position so that the environmental information is transmitted to the electronic rearview mirror for display; wherein, the environmental information is collected by sensors.

[0084] It is understood that the embodiments of this application can monitor the relative position of the vehicle and the congested road section when the vehicle is in a congested area. Based on the relative position, the transmission path of the environmental information corresponding to the relative position is controlled and displayed in real time on the electronic rearview mirror display screen. This helps the user obtain the external environment image corresponding to the vehicle when it is in a congested road section, realizing intelligent interaction between the electronic rearview mirror and the environment. The environmental information in the embodiments of this application is collected by sensors, such as by collecting environmental information corresponding to the target object through surround view cameras or side view cameras. That is, surround view cameras or side view cameras are one of the sensors, but are not limited to surround view cameras and side view cameras.

[0085] In actual implementation, at least one electronic exterior rearview mirror of the vehicle has at least one electronic exterior rearview mirror display screen. The electronic exterior rearview mirror display screen can realize the screen display function of the electronic exterior rearview mirror. The screen content is the information of moving targets collected by the visual sensor when the vehicle is in a congested road section. It can help users achieve intelligent visual perception of the vehicle's surroundings when the vehicle is in a congested road section.

[0086] Optionally, in some embodiments, controlling the transmission path of environmental information corresponding to the relative position according to the relative position includes: sending a control signal to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror; or, receiving the environmental information through the data transmission unit based on the relative position, processing the environmental information, and sending the processing result to the data transmission unit to send the processing result to the electronic rearview mirror through the data transmission unit.

[0087] It is understood that, based on the relative position, the embodiments of this application can send control signals to the data transmission unit to display environmental information in real time on the electronic rearview mirror, helping users obtain the corresponding external environment when the vehicle is in a congested road section; or, based on the relative position, the embodiments of this application can receive environmental information through the data transmission unit, process the environmental information, extract information corresponding to the relative position, obtain the processing result, and send the processing result to the data transmission unit, so that the data transmission unit can send the processing result to the electronic rearview mirror for real-time display, further helping users obtain the corresponding external environment when the vehicle is in a congested road section, improving the vehicle's intelligence, eliminating the need for separate sensors on the electronic rearview mirror, improving device reuse rate, and reducing the requirements for the electronic rearview mirror controller, thus reducing the implementation difficulty.

[0088] In actual implementation, at least one electronic exterior rearview mirror of the vehicle has at least one electronic exterior rearview mirror display screen. The electronic exterior rearview mirror display screen can realize the screen display function of the electronic exterior rearview mirror. The screen content is the environmental information collected by the visual sensor such as the camera when the vehicle is in a congested road section. It can help users achieve intelligent visual perception of the vehicle's surroundings when the vehicle is in a congested road section.

[0089] Optionally, in some embodiments, based on the relative position, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror, including: when the relative position is an approach position where the road segment is in front of the vehicle and the distance between the vehicle and the road segment is less than a first preset threshold, determining whether there is a moving target object behind the vehicle; if there is a target object, then a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller.

[0090] It is understood that the moving target in the embodiments of this application may include, but is not limited to, vehicles, pedestrians, bicycles, motorcycles or tricycles moving to the side or rear of the vehicle. The information of moving targets behind the vehicle can be determined by rearward and lateral sensors. The sensors include, but are not limited to, vehicle cameras, millimeter wave, ultrasonic or lidar, all of which are accessories for intelligent driving.

[0091] In actual implementation, as shown in Table 1, the embodiments of this application can adopt transmission path 1, i.e., bypass link, which does not require processing by the intelligent driving controller and can provide data support for the electronic rearview mirror display, realizing intelligent interaction between the electronic rearview mirror and the environment.

[0092] Table 1

[0093]

[0094] Specifically, when the relative position is such that the road segment is in front of the vehicle and the distance between the vehicle and the road segment is less than a first preset threshold, indicating an approaching position, it is determined whether there is a moving target behind the vehicle. For example, computer vision technology is used to process video footage, and deep learning algorithms are used to identify the target object, identifying and determining the relative position of the vehicle and the congested road segment and / or the moving target behind the vehicle, thus realizing intelligent interaction between the electronic rearview mirror and the environment. When a target exists, this embodiment can use the bypass link of transmission path 1. The intelligent driving controller sends a control signal (connected by the control link) to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror sequentially through the data transmission unit and the electronic rearview mirror controller. This does not require processing by the intelligent driving controller, providing data support for the display of the electronic rearview mirror, further realizing intelligent interaction between the electronic rearview mirror and the environment. For example, Figure 6 As shown, environmental information is collected by sensors and processed serially. It is then transmitted to the deserializer of the data transmission unit via a signal transmission line. The deserializer of the data transmission unit deserializes the data and sends it to the serializer of the data transmission unit. After receiving the transmission instruction from the intelligent driving controller, the serializer sends it to the electronic rearview mirror. This is achieved by using a bypass link for transmission, thus bypassing the intelligent driving controller, improving the timeliness of information and enhancing display efficiency.

[0095] Given that the data transmission unit of the intelligent driving system has a serializer and the serializer has only one bypass interface, there is only one bypass link. Considering that the electronic exterior rearview mirror mainly replaces the physical exterior rearview mirror, and its field of view is mainly for the long distance behind the vehicle, the side view is the most similar. Without changing the architecture, and to ensure the timeliness of the data, this application embodiment can choose to transmit the relevant environmental information of the side view in many application scenarios through the bypass link, thereby providing data support for the electronic exterior rearview mirror display, realizing the intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture.

[0096] It should be noted that the first preset threshold can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0097] Optionally, in some embodiments, as shown in Table 1, a control signal is sent to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror. This also includes: if no target object exists, sending a control signal to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right front-view cameras of the vehicle sequentially through the data transmission unit and the electronic exterior rearview mirror controller to the electronic exterior rearview mirror; the left and right front-view cameras are one of the sensors included in the intelligent driving system.

[0098] Specifically, as shown in Table 1, when the relative position is the road segment in front of the vehicle and the distance between the vehicle and the road segment is less than a first preset threshold, and there is no target object, the bypass link of transmission path 1 is used. The intelligent driving controller sends a control signal (connected by the control link) to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right front-view cameras of the vehicle to the electronic rearview mirrors in sequence through the data transmission unit and the electronic rearview mirror controller. The left and right front-view cameras are one of the sensors included in the intelligent driving system, providing data support for the display of the electronic rearview mirrors and realizing intelligent interaction between the electronic rearview mirrors and the environment, for example, such as Figure 6 As shown, environmental information is collected by sensors and processed serially. Then, it is transmitted to the deserializer of the data transmission unit via a signal transmission line. The deserializer of the data transmission unit deserializes the data and sends it to the serializer of the data transmission unit. After receiving the transmission instruction from the intelligent driving controller, the serializer sends it to the electronic exterior rearview mirror, i.e., the bypass link. This avoids the intelligent driving controller, improving display efficiency and ensuring that the information required by the electronic exterior rearview mirror is extracted from the environmental data collected by the vehicle's existing sensors. This provides data support for the electronic exterior rearview mirror display, realizes intelligent interaction between the electronic exterior rearview mirror and the environment, reduces vehicle costs, and simplifies the vehicle architecture.

[0099] Given that the data transmission unit of the intelligent driving system has a serializer and the serializer has only one bypass interface, there is only one bypass link. Considering that the electronic exterior rearview mirror mainly replaces the physical exterior rearview mirror, and its field of view is mainly for the long distance behind the vehicle, the side view is the most similar. Without changing the architecture, and to ensure the timeliness of the data, this application embodiment can choose to transmit the relevant environmental information of the side view in many application scenarios through the bypass link, thereby providing data support for the electronic exterior rearview mirror display, realizing the intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture.

[0100] It should be noted that the first preset threshold can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0101] Optionally, in some embodiments, as shown in Table 1, a control signal is sent to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror. This includes: when the relative position is in a congested road section, receiving the environmental information collected by the vehicle's left and right surround-view cameras through the data transmission unit, processing the environmental information, and sending the processing result sequentially to the electronic rearview mirror through the intelligent driving controller, the data transmission unit, and the electronic rearview mirror; the left and right surround-view cameras are one of the sensors included in the intelligent driving system.

[0102] As one possible implementation method, as shown in Table 1, in this embodiment, when the relative position is located in a congested road segment, the SOC link of transmission path 2 is used. After receiving the environmental information collected by the vehicle's left and right surround-view cameras through the data transmission unit, the environmental information is processed, and the processing result is sent sequentially through the intelligent driving controller, the data transmission unit, and the electronic rearview mirror to control at least one electronic rearview mirror to display the surround-view camera data, thereby displaying the relevant image or information of the target object. The left and right surround-view cameras are one of the sensors included in the intelligent driving system, providing data support for the display of the electronic rearview mirror and realizing intelligent interaction between the electronic rearview mirror and the environment.

[0103] It should be noted that since the bypass link requires an interface, if the surrounding environmental information is also transmitted through the bypass link, an additional serializer is needed, which increases the cost. Therefore, when using the surrounding cameras to collect environmental information, in order to reduce costs, an additional serializer is not added. Instead, the serializer can be controlled to output the left and right surrounding camera information transmitted based on the SOC link. However, there are various ways to implement this. If cost is not a concern, a serializer can be added to increase timeliness so that the environmental information can also be transmitted through the bypass link. Therefore, those skilled in the art can configure it according to the actual situation, and no specific restrictions are made here.

[0104] Optionally, in some embodiments, as shown in Table 1, a control signal is sent to the data transmission unit based on the relative position to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror. This includes: when the relative position is a congested road segment located behind the vehicle and the distance between the vehicle and the congested road segment is greater than a second preset threshold and the vehicle is about to move away from the congested road segment, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror sequentially through the data transmission unit and the electronic rearview mirror controller; the left and right rearview cameras are one of the sensors included in the intelligent driving system.

[0105] In actual implementation, as shown in Table 1, this embodiment can, when the relative position is such that the congested road segment is behind the vehicle and the distance between the vehicle and the congested road segment is greater than the second preset threshold and the vehicle is about to move away, take the bypass link of transmission path 1. The intelligent driving controller sends a control signal (connected by the control link) to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirrors in sequence through the data transmission unit and the electronic rearview mirror controller. Figure 6 As shown, environmental information is collected by sensors and processed serially. It is then transmitted via a signal transmission line to the deserializer in the data transmission unit. The deserializer deserializes the data and sends it to the serializer in the data transmission unit. After receiving a transmission instruction from the intelligent driving controller, the serializer sends the data to the electronic exterior rearview mirror, i.e., a bypass link. This bypasses the intelligent driving controller, improving display efficiency and further enabling intelligent interaction between the electronic exterior rearview mirror and the environment, thus saving vehicle resources. The left and right rearview cameras are among the sensors included in the intelligent driving system, providing data support for the electronic exterior rearview mirror display and further enabling intelligent interaction between the electronic exterior rearview mirror and the environment.

[0106] Given that the data transmission unit of the intelligent driving system has a serializer and the serializer has only one bypass interface, there is only one bypass link. Considering that the electronic exterior rearview mirror mainly replaces the physical exterior rearview mirror, and its field of view is mainly for the long distance behind the vehicle, the side view is the most similar. Without changing the architecture, and to ensure the timeliness of the data, this application embodiment can choose to transmit the relevant environmental information of the side view in many application scenarios through the bypass link, thereby providing data support for the electronic exterior rearview mirror display, realizing the intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture.

[0107] It should be noted that the second preset threshold can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0108] Optionally, in some embodiments, monitoring the relative position of a vehicle and a congested road segment includes: acquiring navigation information of the vehicle; and determining the relative position based on the navigation information and the location.

[0109] It is understood that the embodiments of this application can obtain vehicle navigation information, such as through GNSS.

[0110] In actual implementation, the embodiments of this application can obtain vehicle navigation information through GNSS, thereby improving the accuracy of navigation information acquisition; the embodiments of this application can determine the relative position based on navigation information and location, thereby ensuring the acquisition of the vehicle's specific location information, providing support for determining whether the vehicle is driving in a congested environment, improving the vehicle's intelligence, enhancing the user experience, and reducing the efficiency of vehicle resource utilization.

[0111] To complement the above embodiments, it can be combined with Figures 8 to 10 As shown, by utilizing high-precision map positioning and map recognition functions, the system determines the vehicle's location information and, in conjunction with vehicle navigation information, determines the relationship between the vehicle's position and congested road sections. Furthermore, it uses high-precision positioning and map information, or sensors such as cameras, to identify the positional relationship between pedestrian crossings and vehicles. For example... Figure 8 As shown, the vehicle's current location information can be obtained through the intelligent driving high-precision positioning function, specifically as follows: Figure 9 As shown, the vehicle's location information is obtained using GNSS and related technologies. This information is then received by the vehicle's TBOX and used in a positioning algorithm to determine the vehicle's location, resulting in the final positioning result. The intelligent driving high-precision map function provides the vehicle map information required by the intelligent driving system, specifically as follows: Figure 10 As shown in the diagram, the left side represents a smooth virtual lane at an intersection. The high-precision map elements include road elements, intersection elements, traffic signal elements, logical relationship elements, and other road object elements. It can receive information from high-precision maps, high-precision positioning, and sensors to achieve reasonable vehicle control, realizing the functions of the intelligent driving domain. This helps to acquire surrounding scene information, assisting users in end-to-end intelligent driving vehicle control and obtaining road information ahead of the path. Road environment information can be obtained through intelligent driving sensor functions, including but not limited to LiDAR, cameras, millimeter-wave radar, and ultrasonic sensors, which can detect the vehicle's surrounding environment in real time to perform obstacle avoidance and other vehicle control behaviors. The vehicle's ignition status and gear information can be transmitted in real time through the vehicle controller to obtain the vehicle's current location and navigation information, providing traffic condition information from the navigation map function to determine the current road congestion situation.

[0112] In step S703, if the vehicle is not in a congested area, the control data transmission unit directly transmits the environmental information collected by the left and right side rearview cameras to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0113] In actual implementation, as shown in Table 1, the above embodiments describe the situation when in a congested road section. Based on the completeness of this application, when not in a congested road section, the control data transmission unit can directly transmit the environmental information collected by the left and right rearview cameras of the vehicle to the electronic exterior rearview mirror controller. The control data transmission unit collects the environmental information of the left and right lane directions through the left and right rearview cameras and controls the serializer to output the bypass link data of the left and right rearview cameras, and then displays the left and right rearview data on the electronic exterior rearview mirror. This clarifies and refines the source of environmental information in the road section scenario, effectively utilizes vehicle resources, reduces vehicle costs, and saves vehicle resources. The left and right rearview cameras in this embodiment are one of the sensors included in the intelligent driving system, which can meet the requirements for the transmission, processing, and display of left and right rearview camera data.

[0114] It should be noted that, given that the data transmission unit of the intelligent driving system has a serializer and the serializer has only one bypass interface, there is only one bypass link. Considering that the electronic exterior rearview mirror mainly replaces the physical exterior rearview mirror, and its field of view is mainly for the long distance behind the vehicle, and the side view is the most similar, without changing the architecture, and to ensure the timeliness of the data, this application embodiment can choose to transmit the relevant environmental information of the side view in many application scenarios through the bypass link, thereby providing data support for the electronic exterior rearview mirror display, realizing the intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture.

[0115] In summary, this application can send environmental information corresponding to the vehicle's relative position to the electronic rearview mirror via a corresponding transmission path when the vehicle is in a congested area, or directly to the electronic rearview mirror when the vehicle is not in a congested area. This provides data support for the electronic rearview mirror display, enabling intelligent interaction between the electronic rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture. Therefore, it solves the problems in related technologies where electronic rearview mirror systems all require separate controllers and cameras, resulting in complex and redundant system architectures, low utilization of vehicle components, difficulty in maximizing the integration of the electronic rearview mirror system with vehicle sensors, reduced utilization of vehicle resources, and increased complexity and cost in the vehicle structure. This application achieves comprehensive and rational utilization of vehicle resources, improving the rationality and practicality of the vehicle structure.
