[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 location of a target object to the electronic exterior rearview mirror via a corresponding transmission path when the vehicle changes lanes, or send it directly to the electronic exterior rearview mirror when there is no target object, 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] When the vehicle is detected to be changing lanes, it is determined whether there is a moving target on the side of the vehicle in the direction of lane change;
[0008] If the target object is present, the position of the target object is monitored, and the transmission path of the environmental information corresponding to the position is controlled according to the 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 target object does not exist, the data transmission unit is controlled to directly transmit the environmental information collected by the side rearview camera on the side of the lane change direction to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror; the side rearview camera is one of the sensors included in the intelligent driving system.
[0010] The above technical solutions can determine whether there is a moving target on the side of the vehicle in the direction of lane change, thereby improving the vehicle's intelligence and enhancing the user experience. When a target is present, environmental information can be transmitted to the electronic rearview mirror for display according to the transmission path, helping users achieve intelligent visual perception of the vehicle's surroundings when changing lanes. When no target is present, environmental information can be directly transmitted to the electronic rearview mirror controller, thereby providing data support for the electronic rearview mirror display and realizing intelligent interaction between the electronic rearview mirror and the environment.
[0011] In conjunction with the first aspect, in some possible implementations, controlling the transmission path of environmental information corresponding to the location based on the location includes:

[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 location 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 moving target is located at the side-front position of the vehicle, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side-front view camera on the lane change direction corresponding to the position to the electronic exterior rearview mirror in sequence through the data transmission unit and the electronic exterior rearview mirror controller; the side-front view camera is one of the sensors included in the intelligent driving system.
[0017] Through the above technical solution, the control data transmission unit can sequentially send the environmental information collected by the side-view camera on the side corresponding to the lane change direction to the electronic exterior rearview mirror through the data transmission unit and the electronic exterior rearview mirror controller. Then, the information required by the electronic exterior rearview mirror can be extracted from the environmental information collected by the vehicle's existing sensors, thereby providing data support for the display of the electronic exterior rearview mirror and realizing intelligent interaction between the electronic exterior rearview mirror and the environment.

[0019] When the moving target is located to the side and rear of the vehicle, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side rearview camera on the side of the lane change direction corresponding to the position to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller.
[0020] Through the above technical solution, the data transmission unit can control the environmental information collected by the side rearview camera on the side corresponding to the lane change direction to be sent to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller. This allows for the extraction of the information required by the electronic rearview mirror from the environmental information collected by the vehicle's existing sensors, thereby providing data support for the electronic rearview mirror display, realizing intelligent interaction between the electronic rearview mirror and the environment, and reducing vehicle costs.
[0021] 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 location to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror includes:
[0022] When the moving target is located at the front and rear sides of the vehicle, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side rearview camera on the side of the lane change direction corresponding to the location to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller.
[0023] Through the above technical solution, when the moving target is located at the front and rear sides of the vehicle, the control data transmission unit can sequentially send the environmental information collected by the side rearview camera on the side corresponding to the lane change direction 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, reducing vehicle costs and saving vehicle resources.
[0024] In combination with the first aspect and the above implementation methods, in some possible implementation methods, after receiving the environmental information based on the location through the data transmission unit, processing the environmental information, and sending the processing result to the data transmission unit, so as to send the processing result to the electronic exterior rearview mirror through the data transmission unit, the following steps are included:
[0025] Based on the location, determine whether there is a risk of collision between the vehicle and the target object;
[0026] If there is a collision risk, the system receives environmental information collected by the surround-view camera in the lane change direction corresponding to the location through the data transmission unit, processes the environmental information, and sends the processing result to the electronic exterior rearview mirror sequentially through the intelligent driving controller, the data transmission unit, and the electronic exterior rearview mirror controller; the surround-view camera is one of the sensors included in the intelligent driving system.
[0027] The above technical solution can ensure that when there is a risk of collision between the vehicle and the target object, the surround-view camera data can be extracted from the environmental information to control at least one electronic exterior rearview mirror to display the surround-view camera data, thereby facilitating the display of relevant images or information of the target object.
[0028] In combination with the first aspect and the above implementation methods, in some possible implementations, the method further includes:

[0030] Through the above technical solution, when it is detected that the vehicle is not in the process of changing lanes, the control data transmission unit can directly transmit the environmental information collected by the side rearview camera on the side of the lane change direction to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror.

[0061] Figure 12 This is a structural schematic diagram of a vehicle provided according to an embodiment of this application. Detailed Implementation
[0062] 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.
[0063] 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.
[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] The application scenarios or system architecture of the embodiments of this application will be described next. See also Figure 5 The 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.
[0069] 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.
[0070] 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.
[0071] The transmission path can be, but is not limited to, two types of paths:
[0072] 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.
[0073] 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.
[0074] 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. Without changing the architecture, the output utilizes the interface of one serializer of the intelligent data transmission unit 12 to ensure data timeliness. Therefore, this embodiment of the application will choose to transmit relevant environmental information of side views in many application scenarios through a bypass link without changing the architecture, especially considering that electronic exterior rearview mirrors mainly replace physical exterior rearview mirrors, thus improving the field of view. Primarily targeting long distances behind vehicles, the side-view field of view is the most similar, and the bypass link is fast, meeting timeliness requirements. However, if the surrounding environment information is also transmitted through the bypass link, an additional serializer is needed, increasing costs. Therefore, it is possible to use the SOC link to transmit the surrounding environment information, reducing costs and simplifying the architecture. However, there are various implementation methods. For example, the surrounding environment information can be transmitted through the SOC link, while the side-view environment 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 imposed here.
[0075] Figure 7 This is a schematic flowchart illustrating a display method for an electronic exterior rearview mirror provided in an embodiment of this application.
[0076] For example, such as Figure 7 As shown, the method includes the following steps:
[0077] In step S701, when it is detected that the vehicle is in the process of changing lanes, it is determined whether there is a moving target on the side of the vehicle in the direction of lane change.
[0078] It is understandable that, since the steering lever and steering wheel are important components of the vehicle's steering system, enabling lane changing and steering operations, the lane changing process in this embodiment may include, but is not limited to, the following: from the start of the lane change, if the rotation value of the steering lever is greater than a certain rotation value obtained from the actual curvature of the current lane, or the actual steering wheel angle is greater than a certain angle obtained from the actual curvature of the current lane, until the end of the lane change, the rotation value of the steering lever is equal to a certain rotation value obtained from the actual curvature of the current lane, or the actual steering wheel angle is equal to a certain angle obtained from the actual curvature of the current lane. Furthermore, the side of the vehicle's lane-changing direction in this embodiment can be understood as the side of the vehicle's lane-changing direction. For example, if the left turn signal is illuminated, then the left side of the driving direction is the side of the lane-changing direction; similarly, if the steering wheel is turned to the left, then the left side of the driving direction is the side of the lane-changing direction. Additionally, determining whether there is a moving target on the side of the lane-changing direction can be, but is not limited to, using environmental information.
[0079] For example, in this embodiment of the application, when the rotation value of the turn signal lever is greater than a certain rotation value obtained from the actual curvature of the current lane, it can be recognized that the vehicle is in the process of changing lanes. At this time, it can be determined whether there is a moving target on the side of the lane change direction. For example, if the vehicle is currently traveling in the middle lane of the road and wants to change to the left lane, the user can first observe the rearview mirror to determine that there is a certain distance between the vehicle behind and the current vehicle, and then pull down the turn signal lever to turn on the left turn signal. Then the left side of the driving direction is the side of the lane change direction. Similarly, if the steering wheel is turned to the left, the left side of the driving direction is the side of the lane change direction. At the same time or before changing lanes to the left lane while maintaining a stable speed, based on the environmental information collected by the sensor, the intelligent driving controller realizes the vehicle's intelligent driving lane change strategy or the driver's lane change operation. That is, during the lane change process, it is determined whether there is a moving target on the side of the lane change direction.
[0080] For example, in this embodiment of the application, when the actual steering wheel angle is greater than a certain angle obtained from the actual curvature of the current lane, it can be recognized that the vehicle is in the process of changing lanes. At this time, it can be determined whether there is a moving target on the side of the lane change direction. For example, if the current vehicle is traveling in the middle lane of the road and wants to change to the right lane, the user can first observe the rearview mirror, and then determine that there is a certain distance between the vehicle behind and the current vehicle, and then move the steering stalk upward to turn on the right turn signal. Then the right side of the driving direction is the side of the lane change direction. Similarly, if the steering wheel is turned to the right, then the right side of the driving direction is the side of the lane change direction. At the same time or before changing lanes to the right lane while maintaining a stable speed, based on the environmental information collected by the sensor, the intelligent driving controller realizes the vehicle's intelligent driving lane change strategy or the driver's lane change operation. That is, during the lane change process, it can be determined whether there is a moving target on the side of the lane change direction, which improves the intelligence of the vehicle and enhances the user experience.
[0081] In step S702, if a target object exists, the position of the target object is monitored, and the transmission path of the environmental information corresponding to the position is controlled according to the 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 sensors.
[0082] It is understood that, in the embodiments of this application, when a target object is present, the transmission path of environmental information corresponding to the target object's position can be controlled, and the information can be displayed in real time on the electronic rearview mirror display screen. This helps the user obtain the corresponding external environment image when the vehicle changes lanes, realizing intelligent interaction between the electronic rearview mirror and the environment. In the embodiments of this application, the environmental information is collected by sensors, such as by collecting the environmental information corresponding to the target object through a surround-view camera or a side-view camera. That is, the surround-view camera or the side-view camera is one of the sensors, but it is not limited to surround-view cameras and side-view cameras.
[0083] 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 the moving target object collected by the visual sensor during the vehicle's lane change process, which can help the user achieve intelligent visual perception of the vehicle's surroundings when the vehicle changes lanes.
[0084] Optionally, in some embodiments, controlling the transmission path of environmental information corresponding to the location based on the location includes: sending a control signal to the data transmission unit based on the location 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 location, 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.
[0085] It is understood that, based on the position of each target object, 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 image when the vehicle changes lanes; or, based on the position of each target object, the embodiments of this application can receive environmental information through the data transmission unit, process the environmental information, extract information corresponding to the 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 image when the vehicle changes lanes, improving the intelligence of the vehicle, eliminating the need for separate sensors on the electronic rearview mirror, improving the device reuse rate, and reducing the requirements for the electronic rearview mirror controller, thus reducing the implementation difficulty.
[0086] 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 sensors such as cameras during the vehicle's lane change process, which can help users achieve intelligent visual perception of the vehicle's surroundings when the vehicle changes lanes.
[0087] Optionally, in some embodiments, based on the location, 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. This includes: when the location is such that the moving target is located at the side front position of the vehicle, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side front view camera on the lane change direction corresponding to the location to the electronic exterior rearview mirror in sequence through the data transmission unit and the electronic exterior rearview mirror controller; the side front view camera is one of the sensors included in the intelligent driving system.
[0088] It is understood that the moving target in the embodiments of this application may include vehicles, pedestrians, bicycles, motorcycles or tricycles moving to the side and rear of the vehicle. The information of the moving target 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, etc., all of which are accessories for intelligent driving.
[0089] In actual implementation, as shown in Table 1, when the moving target is located at the front side of the vehicle, such as within 50m, this embodiment can use transmission path 1, i.e., bypass link. Specifically, the intelligent driving controller sends a control signal (connected by a control link) to the data transmission unit, so as to control the data transmission unit to send the environmental information collected by the side front view camera on the lane change direction corresponding to the position to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller. No processing by the intelligent driving controller is required. The side front view camera is one of the sensors included in the intelligent driving system, which provides data support for the display of the electronic rearview mirror and realizes intelligent interaction between the electronic rearview mirror and the environment.

[0092]
[0093] Specifically, when the intelligent driving controller detects that the vehicle is changing lanes, it compares the steering lever or steering wheel angle information with the road curvature. If the steering lever / steering wheel angle is greater than a certain value of the current lane curvature, and a moving object is detected on the side of the lane change direction, and the moving object is located within 50m of the vehicle's front side, the controller uses the front-view camera on the lane change direction as the data source. It then uses the bypass link of transmission path 1 and sequentially sends the data to the electronic rearview mirror through the data transmission unit and the electronic rearview mirror controller. 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.
[0094] 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.
[0095] In addition, to complement the above embodiments, such as Figure 8 The diagram illustrates the information interaction of an intelligent driving system. It can obtain the vehicle's current location information through high-precision positioning, acquire high-precision map information through high-precision maps, and obtain environmental information through sensors. This information is then transmitted to the intelligent driving controller to determine the lane-changing process. The system can detect the vehicle's surrounding environment in real time to perform obstacle avoidance and other vehicle control actions. It can also obtain environmental information through sensors and transmit this information to the intelligent driving controller to determine the lane-changing direction side-view data from the side-view camera. This allows control of at least one electronic exterior rearview mirror to display the lane-changing direction side-view data, thereby clarifying and refining the source of the displayed environmental information. This effectively utilizes vehicle resources while reducing vehicle costs and simplifying the vehicle architecture.
[0096] Optionally, in some embodiments, as shown in Table 1, a control signal is sent to the data transmission unit based on the location to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror. This includes: when the location is such that the moving target is located at the side and rear of the vehicle, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side rearview camera on the side corresponding to the lane change direction to the electronic exterior rearview mirror in sequence through the data transmission unit and the electronic exterior rearview mirror controller.
[0097] Specifically, as shown in Table 1, in this embodiment of the application, when a moving target is detected on the side of the vehicle changing lanes, and the moving target is located at the rear side of the vehicle (e.g., within 50m of the rear side), the side rear-view camera in the lane-changing direction can be used as the data source. Using the bypass link of transmission path 1, the intelligent driving controller sends a control signal (connected via the control link) to the data transmission unit. This controls the data transmission unit to sequentially send the environmental information collected by the side rear-view camera on the lane-changing direction corresponding to the location to the electronic rear-view mirror via the data transmission unit and the electronic rear-view mirror controller. For example, ... 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.
[0098] 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.
[0099] Optionally, in some embodiments, as shown in Table 1, a control signal is sent to the data transmission unit based on the location to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror. This includes: when the location is such that the moving target is located at the front and rear sides of the vehicle, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side rearview camera on the side of the lane change direction corresponding to the location to the electronic exterior rearview mirror in sequence through the data transmission unit and the electronic exterior rearview mirror controller.
[0100] As one possible implementation method, as shown in Table 1, in this embodiment of the application, when a moving target is detected on the side of the vehicle changing lanes, and the moving target is located at the front and rear side of the vehicle (e.g., within 50m of the front and rear side), a side-rear view camera in the lane-changing direction can be used. Using the bypass link of transmission path 1, the intelligent driving controller sends a control signal (connected via the control link) to the data transmission unit. This controls the data transmission unit to sequentially send the environmental information collected by the side-rear view camera on the lane-changing direction corresponding to the location to the electronic rearview mirror via 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 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 bypasses the intelligent driving controller, improves display efficiency, and further realizes intelligent interaction between the electronic exterior rearview mirror and the environment, saving vehicle resources.
[0101] 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.
[0102] Optionally, in some embodiments, as shown in Table 1, after receiving environmental information through the data transmission unit based on location, 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 exterior rearview mirror through the data transmission unit. This includes: determining whether there is a collision risk between the vehicle and the target object based on the location; if there is a collision risk, then after receiving environmental information collected by the surround-view camera in the lane-changing direction corresponding to the location through the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic exterior rearview mirror sequentially through the intelligent driving controller, the data transmission unit, and the electronic exterior rearview mirror controller through the data transmission unit; the surround-view camera is one of the sensors included in the intelligent driving system.
[0103] It is understood that the collision risk in the embodiments of this application may be, but is not limited to, a moving target object being less than a certain distance, such as 10m, between its front or side and the side or front and rear distance of a lane-changing vehicle.
[0104] For example, as shown in Table 1, this application embodiment can determine whether there is a risk of lane change collision between the vehicle and the target object based on the location. For instance, when the distance between the vehicle and the target object from the front or side or from the front or rear is less than 10m, it is determined that there is a risk of lane change collision between the vehicle and the target object, thereby providing support for the subsequent display of environmental data. When there is a risk of lane change collision, the SOC link of transmission path 2 is used. After receiving the environmental information collected by the surround-view camera in the lane change direction corresponding to the location through the data transmission unit, the environmental information is processed. The processing result is then sent to the electronic rearview mirror through the intelligent driving controller, the data transmission unit, and the electronic rearview mirror controller in sequence through the data transmission unit, so as 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.
[0105] 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 camera to collect environmental information, in order to reduce costs, the serializer is not added. Instead, the serializer can be controlled to output the surrounding camera information of the lane change direction 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.
[0106] In step S703, if there is no target object, the control data transmission unit directly transmits the environmental information collected by the side rearview camera on the lane change direction to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror; the side rearview camera is one of the sensors included in the intelligent driving system.
[0107] In actual implementation, as shown in Table 1, the above embodiments describe the situation where a target object exists. Based on the completeness of this application, when no target object exists during lane changing, the control data transmission unit can directly transmit the environmental information collected by the side rearview camera on the lane changing direction to the electronic exterior rearview mirror controller. For example, in this embodiment, when changing lanes from the middle lane to the left lane, if no target object exists during the lane changing process, the control data transmission unit collects the environmental information of the left lane direction through the side rearview camera and controls the serializer to output the bypass link data of the side rearview camera on the lane changing direction. Then, the side rearview data on the lane changing direction is displayed on the electronic exterior rearview mirror. This clarifies and refines the source of the displayed environmental information for lane changing scenarios, effectively utilizing vehicle resources while reducing vehicle costs and saving vehicle resources. The side rearview camera in this embodiment is one of the sensors included in the intelligent driving system, which can meet the requirements for the transmission, processing, and display of side rearview camera data.
[0108] 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.
[0109] Optionally, in some embodiments, the method further includes: when it is detected that the vehicle is not in the process of changing lanes, controlling the data transmission unit to directly transmit the environmental information collected by the side rearview camera on the side of the lane change direction to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror.
[0110] In some embodiments, when it is detected that the vehicle is not in the process of changing lanes, based on the bypass link of transmission path 1, the intelligent driving controller controls the data transmission unit to directly transmit the environmental information collected by the side rearview camera on the side of the lane change direction to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror. This further clarifies and refines the source of the displayed environmental information, improves the timeliness of the display while making effective use of vehicle resources, avoids additional vehicle costs, and saves vehicle resources.
[0111] The following is combined with Figure 9 and Figure 10 As shown, the intelligent driving system of the vehicle according to an embodiment of the present invention will be further described in detail with a specific example.
[0112] like Figure 9 As shown, the vehicle's location information can be obtained using GNSS (Global Navigation Satellite System) 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 in this embodiment provides the vehicle map information required by the intelligent driving system, assisting users in end-to-end intelligent driving control. It can obtain road information ahead of the path in advance, specifically as follows... Figure 10 As shown, the left side of the figure 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. The intelligent driving controller in this embodiment of the invention can receive information from high-precision maps, high-precision positioning, sensors, etc., to perform reasonable vehicle control and realize the functions of the intelligent driving domain.
[0113] In summary, this application can send environmental information corresponding to the location of a target object to the electronic rearview mirror via a corresponding transmission path when the vehicle changes lanes, or directly to the electronic rearview mirror when no target object exists. 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 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, difficulty in maximizing the integration of the electronic rearview mirror system with vehicle sensors, reduced utilization of vehicle resources, and increased complexity and cost. This application achieves comprehensive and rational utilization of vehicle resources, improving the rationality and practicality of the vehicle structure.

The data transmission unit includes a serializer with only one bypass interface, and the first transmission path directly transmits the environmental information through the bypass interface. Alternatively, the second transmission path involves receiving the environmental information through the data transmission unit based on the location, processing the environmental information, and sending the processing result back to the data transmission unit, which then sends the processing result to the electronic rearview mirror. The environmental information transmitted in the second transmission path is the environmental information acquired by the surround-view camera. The second transmission path transmits the environmental information after processing it through the intelligent driving controller.
