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 width-restricted driving conditions to the electronic exterior rearview mirror via a corresponding transmission path when the passable space is less than or equal to a preset space, or directly send it to the electronic exterior rearview mirror when the passable space is greater than the preset space. This provides data support for the display of the electronic exterior rearview mirror, realizes intelligent interaction between the electronic exterior rearview mirror and the environment, reduces vehicle costs, and simplifies 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 identified as being in a width-restricted driving condition, the system determines whether the passable space of the width-restricted device on the road is greater than a preset space.

[0008] If the passable space is less than or equal to the preset space, the vehicle's position is monitored, and a first transmission path for environmental information corresponding to the position is controlled according to the position, so that the environmental information is transmitted to the electronic exterior rearview mirror for display according to the first transmission path; wherein, the environmental information is collected by the sensor;

[0009] If the passable space is greater than the preset space, the vehicle speed is obtained, and a second transmission path for environmental information corresponding to the vehicle speed is controlled according to the vehicle speed, so that the environmental information is transmitted to the electronic rearview mirror for display according to the second transmission path.

[0010] The above technical solutions enable the system to determine whether the passable space of the width-limiting devices on the road is greater than a certain limit, thereby providing data support for the electronic rearview mirror display and improving the vehicle's intelligence. When the passable space is less than or equal to a certain limit, environmental information is transmitted to the electronic rearview mirror via a first transmission path for display, ensuring efficient utilization of vehicle resources. When the passable space is greater than a certain limit, environmental information is transmitted to the electronic rearview mirror via a second transmission path for display, providing data support for the electronic rearview mirror display. This achieves intelligent interaction between the electronic rearview mirror and the environment, reduces vehicle costs, and simplifies the vehicle architecture.

[0011] In conjunction with the first aspect, in some possible implementations, the second transmission path for controlling the environmental information corresponding to the vehicle speed includes:

[0012] When the vehicle speed is greater than or equal to a preset speed, the data transmission unit controls the transmission of environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror controller via the data transmission unit and the electronic rearview mirror controller, so as to display it on the electronic rearview mirror; the left and right rearview cameras are one of the sensors included in the intelligent driving system;

[0013] When the vehicle speed is less than the preset vehicle speed, the first transmission path of the environmental information corresponding to the location is controlled according to the location, so that the environmental information is transmitted to the electronic rearview mirror for display in sequence through the data transmission unit and the electronic rearview mirror controller or through the intelligent driving controller, the data transmission unit and the electronic rearview mirror controller in sequence.

[0014] The above technical solution enables the transmission of environmental information to the electronic rearview mirror for display according to different vehicle speeds and transmission paths, thereby improving display efficiency, providing data support for the electronic rearview mirror display, and realizing intelligent interaction between the electronic rearview mirror and the environment.

[0015] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the step of controlling the first transmission path of the environmental information corresponding to the location based on the location includes:

[0016] 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;

[0017] Alternatively, based on the location, 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.

[0018] The above technical solution enables the processing results to be sent to the electronic rearview mirror via the data transmission unit based on the location, thereby achieving intelligent interaction between the electronic rearview mirror and the environment, ensuring the comprehensiveness of environmental data extraction, improving the intelligence and practicality of the vehicle, and enhancing the user experience.

[0019] 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:

[0020] When the vehicle is passing through a width-restricted device, the system receives environmental information collected by the left and right surround-view cameras corresponding to the location via the data transmission unit, processes the environmental information, and then sends the processing result sequentially to the electronic exterior rearview mirror via the intelligent driving controller, the data transmission unit, and the electronic exterior rearview mirror controller. The left and right surround-view cameras are one of the sensors included in the intelligent driving system.

[0021] The above technical solution enables the vehicle to receive environmental information from the left and right surround-view cameras at the location where it is passing through a width-restriction device. This information is then processed to provide data support for the electronic rearview mirror display, thereby improving the vehicle's intelligence and practicality.

[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 location 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 vehicle completes its passage through the width restriction device at the specified location, 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 corresponding to the specified location to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller.

[0024] Through the above technical solution, when the vehicle completes the passage through the width restriction device, the control data transmission unit can sequentially send the environmental information collected by the left and right rearview cameras corresponding to the location 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 and saving vehicle resources.

[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 location 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 vehicle has not passed the width restriction device at the location, determine whether there is a moving target object behind the side of the vehicle;

[0027] 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 corresponding to the position to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller.

[0028] The above technical solution enables the determination of whether there is a moving target behind the vehicle when the vehicle has not passed the width restriction device, providing support for sending data to the electronic rearview mirror. When a target is present, the control data transmission unit can sequentially send the environmental information collected by the left and right rearview cameras corresponding to the location to the electronic rearview mirror through the data transmission unit and the electronic rearview mirror controller, thereby improving display efficiency.

[0029] 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 rearview mirror further includes:

[0030] 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 corresponding to the position to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller; the right front-view camera is one of the sensors included in the intelligent driving system.

[0031] Through the above technical solution, when no target object is present, the control data transmission unit can sequentially send the environmental information collected by the left and right front-view cameras corresponding to the position 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 and saving vehicle resources. In this embodiment, the right front-view camera is one of the sensors included in the intelligent driving system, which can meet the requirements for the transmission, processing and display of side-view camera data.

[0032] Secondly, a display device for an electronic exterior rearview mirror is provided, applied to an intelligent driving controller of a vehicle, the vehicle including: 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 device includes:

[0035] In conjunction with the second aspect, in some possible implementations, the control module includes:

[0036] The first control unit is used to control the data transmission unit to transmit the environmental information collected by the left and right rearview cameras of the vehicle directly to the electronic rearview mirror controller through the data transmission unit and the electronic rearview mirror controller when the vehicle speed is greater than or equal to a preset vehicle speed, so as to display it on the electronic rearview mirror; the left and right rearview cameras are one of the sensors included in the intelligent driving system;

[0037] The transmission unit is configured to, when the vehicle speed is less than the preset vehicle speed, control the first transmission path of the environmental information corresponding to the location according to the location, so that the environmental information is transmitted sequentially through the data transmission unit and the electronic exterior rearview mirror controller or sequentially through the intelligent driving controller, the data transmission unit and the electronic exterior rearview mirror controller to the electronic exterior rearview mirror for display.

[0038] In combination with the second aspect and the above implementation methods, in some possible implementations, the control module includes:

[0039] The second control unit is configured to send a control signal to the data transmission unit based on the location, so as to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror;

[0040] Alternatively, the transmitting unit is configured to receive the environmental information through the data transmission unit based on the location, process the environmental information, and send the processing result to the data transmission unit so that the processing result can be sent to the electronic rearview mirror through the data transmission unit.

[0041] In combination with the second aspect and the above implementation methods, in some possible implementations, the sending unit includes:

[0042] The transmitting subunit is configured to, when the vehicle is passing through a width-restricting device, receive environmental information collected by the left and right surround-view cameras corresponding to the location via the data transmission unit, process the environmental information, and transmit the processing result sequentially to the electronic exterior rearview mirror via the intelligent driving controller, the data transmission unit, and the electronic exterior rearview mirror controller; the left and right surround-view cameras are one of the sensors included in the intelligent driving system.

[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 6As 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. 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.

[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 a width-restricted driving condition, it is determined whether the passable space of the width-restricted device is greater than the preset space based on the width-restricted device on the road.

[0078] It is understood that the width-restricted driving conditions in the embodiments of this application may be, but are not limited to, the state when the vehicle is in a width-restricted scenario during driving; the width-restricting devices in the embodiments of this application may be, but are not limited to, limit posts, limit stakes, and railings; the passable space in the embodiments of this application can be understood as the space that the vehicle can pass through, such as the passable width between the limit stakes.

[0079] In actual implementation, the embodiments of this application can identify scenarios where the vehicle is in a width-restricted driving condition, such as when a width-restricted device is detected in front of the vehicle. At this time, it can determine whether the passable space of the width-restricted device is greater than a certain space based on the width-restricted device such as the limit post, limit post and railing, thereby providing data support for the electronic rearview mirror display and improving the intelligence of the vehicle.

[0080] It should be noted that the preset space can be set by those skilled in the art according to the actual situation, such as according to the width of the vehicle, and no specific restrictions are made here.

[0081] In step S702, if the passable space is less than or equal to the preset space, the vehicle's position is monitored, and the first 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 exterior rearview mirror for display according to the first transmission path; wherein, the environmental information is collected by sensors.

[0082] It is understood that the space size judgment standard in this application embodiment is, for example, a comparison between the width limit and the vehicle width plus 80cm. When the width limit is less than the vehicle width plus 80cm, it indicates that the space is small. The environmental information in this application embodiment is collected by sensors, such as by collecting environmental information corresponding to the location through surround view cameras or side view cameras. That is, surround view cameras or side view cameras are one of the sensors, but not limited to surround view cameras and side view cameras.

[0083] In actual implementation, as shown in Table 1, the embodiments of this application can monitor the vehicle's position when the space is less than or equal to a certain space, i.e., when the space is small. Based on the position, the first transmission path of the environmental information corresponding to the position is controlled. The embodiments of this application can adopt transmission path 1, i.e., using a bypass link. Specifically, the intelligent driving controller sends a control signal (connected by a control link) to the data transmission unit so that the environmental information is transmitted to the electronic rearview mirror for display according to the first transmission path, ensuring that the vehicle resources are effectively utilized while reducing vehicle costs and saving vehicle resources.

[0084] Table 1

[0085]

[0086] It should be noted that the preset space can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0087] Optionally, in some embodiments, controlling the first 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.

[0088] It is understandable that in this embodiment, a large space with low vehicle speed indicates that the user needs to pay attention to the surrounding environment. Therefore, when the space is small, the display can be based on location. Thus, this embodiment can send a control signal to the data transmission unit based on location, thereby controlling the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror, helping the user obtain the corresponding external environment image when the vehicle is in a width-restricted situation. Alternatively, this embodiment can receive environmental information through the data transmission unit based on location, process the environmental information, extract the information corresponding to the location, 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 the user obtain the corresponding external environment image when the vehicle is in a width-restricted situation, improving the vehicle's intelligence, eliminating the need for a separate sensor for the electronic rearview mirror, increasing the device reuse rate, and reducing the requirements for the electronic rearview mirror controller, thus reducing the implementation difficulty.

[0089] 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 driving process, which can help users achieve intelligent visual perception of the vehicle's surroundings while the vehicle is in motion.

[0090] Optionally, in some embodiments, as shown in Table 1, based on location, after receiving 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 exterior rearview mirror through the data transmission unit. This includes: when the vehicle is passing through a width-restricting device, receiving environmental information collected by the left and right surround-view cameras corresponding to the location through the data transmission unit, processing the environmental information, and sending the processing result sequentially to the electronic exterior rearview mirror through the intelligent driving controller, the data transmission unit, and the electronic exterior rearview mirror controller through the data transmission unit; the left and right surround-view cameras are one of the sensors included in the intelligent driving system.

[0091] For example, as shown in Table 1, in this embodiment, when the vehicle is passing through a width-restricting device, the environmental information collected by the left and right surround-view cameras corresponding to the location can be received by the data transmission unit. The environmental information is then processed and transmitted via the SOC link through transmission path 2. The processing results are then sequentially sent to the electronic rearview mirror through the intelligent driving controller, the data transmission unit, and the electronic rearview mirror controller. This extracts the information needed by the electronic rearview mirror from the environmental data collected by the vehicle's existing sensors, providing data support for the electronic rearview mirror display. This enables intelligent interaction between the electronic rearview mirror and the environment, ensuring the comprehensiveness of environmental data extraction, improving the vehicle's intelligence and practicality, and enhancing the user experience. In this embodiment, the left and right surround-view cameras are one of the sensors included in the intelligent driving system, which can meet the requirements for the transmission, processing, and display of surround-view camera data.

[0092] It should be noted that since the bypass link requires an interface, it increases costs. Therefore, when collecting environmental information through the surround-view camera, in order to reduce costs, an additional serializer is not added. Instead, the serializer can be controlled to output the driving direction surround-view 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 also goes through the bypass link. Therefore, those skilled in the art can set it up according to the actual situation, and no specific restrictions are made here.

[0093] 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 where the vehicle has completed passing through the width restriction device, 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 corresponding to the location to the electronic exterior rearview mirror in sequence through the data transmission unit and the electronic exterior rearview mirror controller.

[0094] As one possible implementation method, as shown in Table 1, in this embodiment, when the vehicle completes its passage through the width-restricted device, it uses 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, which then controls the data transmission unit to sequentially transmit the environmental information collected by the left and right rearview cameras corresponding to the location to the electronic rearview mirror via the data transmission unit and the electronic rearview mirror controller. Figure 6As 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. This utilizes a bypass link, thus bypassing the intelligent driving controller, improving display efficiency, further realizing intelligent interaction between the electronic exterior rearview mirror and the environment, and saving vehicle resources.

[0095] It should be noted that, given that there is only one bypass link and the output is an interface of a serializer using the intelligent data transmission unit, the embodiments of this application will transmit the relevant environmental information of the side view through the bypass link, making it more timely, more in line with actual applications, and improving the reliability and practicality of the method. However, there are many specific implementation methods, which can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[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 rearview mirror. This includes: when the location is such that the vehicle has not passed the width restriction device, determining whether there is a moving target object behind the side of the vehicle; if there is a target object, then 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 rearview cameras corresponding to the location to the electronic rearview mirror sequentially through the data transmission unit and the electronic rearview mirror controller.

[0097] In actual implementation, as shown in Table 1, in this embodiment, when the vehicle is not at the width-restricted location, it determines whether there is a moving target behind the vehicle to provide support for subsequently sending data to the electronic rearview mirror. If a target exists, the bypass link of transmission path 1 is used, and 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 corresponding to the location to the electronic rearview mirror sequentially 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 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.

[0098] It should be noted that, given that there is only one bypass link and the output is an interface of a serializer using the intelligent data transmission unit, the embodiments of this application will transmit the relevant environmental information of the side view through the bypass link, making it more timely, more in line with actual applications, and improving the reliability and practicality of the method. However, there are many specific implementation methods, which can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[0099] To implement the above embodiments, such as Figure 8 As shown, road environment information and vehicle surrounding environment information can be obtained through intelligent driving sensor functions. These intelligent driving sensors include, but are 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. Target objects include, but are not limited to, moving and stationary objects. Moving targets include, but are not limited to, vehicles, pedestrians, bicycles, motorcycles, and tricycles, while stationary targets include, but are not limited to, bollards / posts, railings, water-filled barriers, cones, and walls. This application embodiment can achieve reasonable vehicle control by receiving information from high-precision maps, high-precision positioning, and sensors, thereby improving vehicle intelligence, reducing vehicle costs, and simplifying vehicle architecture.

[0100] Optionally, in some embodiments, as shown in Table 1, 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 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 corresponding to the location sequentially through the data transmission unit and the electronic exterior rearview mirror controller to the electronic exterior rearview mirror; the right front-view camera is one of the sensors included in the intelligent driving system.

[0101] Specifically, in this embodiment, when no target object is present, the bypass link of transmission path 1 can be used. The intelligent driving controller sends a control signal (connected via a control link) to the data transmission unit, which then controls the data transmission unit to sequentially transmit the environmental information collected by the left and right front-view cameras corresponding to the location to the electronic rearview mirror via the data transmission unit and the electronic rearview mirror controller. In this embodiment, the right front-view camera is one of the sensors included in the intelligent driving system, which can meet the requirements for the transmission, processing, and display of side-view camera data, such as... Figure 6As 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. This utilizes a bypass link, thus bypassing the intelligent driving controller, improving display efficiency, further realizing intelligent interaction between the electronic exterior rearview mirror and the environment, and saving vehicle resources.

[0102] It should be noted that, given that there is only one bypass link and the output is an interface of a serializer using the intelligent data transmission unit, the embodiments of this application will transmit the relevant environmental information of the side view through the bypass link, making it more timely, more in line with actual applications, and improving the reliability and practicality of the method. However, there are many specific implementation methods, which can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[0103] In step S703, if the passable space is greater than the preset space, the vehicle speed is obtained, and the second transmission path of the environmental information corresponding to the vehicle speed is controlled according to the vehicle speed, so that the environmental information is transmitted to the electronic rearview mirror for display according to the second transmission path.

[0104] It is understood that the space size judgment standard in this application embodiment is: the comparison between the width limit and the vehicle width plus 80cm. When the width limit is greater than the vehicle width plus 80cm, it indicates that the space is larger.

[0105] It should be noted that if the space is large but the vehicle speed is below 15 kph (kilometers per hour), it is equivalent to the logic of a small space.

[0106] In this embodiment, the large space but low vehicle speed indicates that the user is not at ease and wants to pay attention to the surrounding environment. If the space is large but the vehicle speed is less than 15 kph (kilometers per hour), it is equivalent to the logic of a small space.

[0107] In actual implementation, as shown in Table 1, when the passable space is greater than a certain amount, the vehicle speed can be obtained. Based on the vehicle speed, a second transmission path for environmental information corresponding to the vehicle speed is controlled so that the environmental information is transmitted to the electronic rearview mirror for display. This provides data support for the display of the electronic rearview mirror, realizes intelligent interaction between the electronic rearview mirror and the environment, reduces vehicle costs, and simplifies the vehicle architecture.

[0108] It should be noted that the preset space can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0109] Optionally, in some embodiments, controlling the second transmission path of environmental information corresponding to the vehicle speed according to the vehicle speed includes: when the vehicle speed is greater than or equal to a preset vehicle speed, controlling the data transmission unit to transmit the environmental information collected by the left and right rearview cameras of the vehicle directly to the electronic rearview mirror controller through the data transmission unit and the electronic rearview mirror controller in sequence, so as to display it on the electronic rearview mirror; the left and right rearview cameras are one of the sensors included in the intelligent driving system; when the vehicle speed is less than the preset vehicle speed, controlling the first transmission path of environmental information corresponding to the position according to the position, so that the environmental information is transmitted to the electronic rearview mirror for display through the data transmission unit and the electronic rearview mirror controller in sequence or through the intelligent driving controller, the data transmission unit and the electronic rearview mirror controller in sequence.

[0110] In actual implementation, this embodiment of the application can, when the vehicle speed is greater than or equal to a certain speed, control the data transmission unit to transmit the environmental information collected by the left and right rearview cameras of the vehicle directly to the electronic rearview mirror controller via the data transmission unit and the electronic rearview mirror controller, so as to display it on the electronic rearview mirror. For example, Figure 6 As shown, environmental information is collected by sensors and processed serially, 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 a transmission instruction from the intelligent driving controller, the serializer sends the data to the electronic rearview mirror. This utilizes a bypass link, bypassing the intelligent driving controller, thus improving display efficiency and providing data support for the electronic rearview mirror display, enabling intelligent interaction between the electronic rearview mirror and the environment. In this embodiment, when the vehicle speed is below a certain speed, the first transmission path of the environmental information corresponding to the location is controlled according to the location, so that the environmental information is transmitted sequentially through the data transmission unit and the electronic rearview mirror controller, or sequentially through the intelligent driving controller, the data transmission unit, and the electronic rearview mirror controller, to the electronic rearview mirror for display. This further realizes intelligent interaction between the electronic rearview mirror and the environment, reduces vehicle costs, and simplifies the vehicle architecture.

[0111] It should be noted that, given that there is only one bypass link and the output is an interface of a serializer using the intelligent data transmission unit, the embodiments of this application will transmit the relevant environmental information of the side view through the bypass link, making it more timely, more in line with actual applications, and improving the reliability and practicality of the method. However, there are many specific implementation methods, which can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[0112] It should be noted that the preset vehicle speed can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0113] In summary, this application can transmit environmental information corresponding to the vehicle's width-restricted driving conditions to the electronic exterior rearview mirror via a corresponding transmission path when the passable space is less than or equal to a preset space, or directly to the electronic exterior rearview mirror when the passable space is greater than the preset space. This provides data support for the electronic exterior rearview mirror display, enabling intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture. Therefore, it solves the problems in related technologies where electronic exterior 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 exterior 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.
