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 obtain the information required by the electronic exterior rearview mirror from the environmental data collected by the vehicle's existing sensors based on the surrounding scene when the vehicle is parked or starting, 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 saving vehicle resources.

[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 parking or starting scenario, it is determined whether the vehicle is in a parking area.

[0008] If the vehicle is in the parking area, the surrounding space information of the vehicle is detected to obtain a detection result. Based on the detection result, the transmission path of the environmental information corresponding to the detection result is controlled so that the environmental information is transmitted to the electronic rearview mirror for display according to the transmission path; wherein, the environmental information is collected by the sensor.

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

[0010] Through the above technical solution, when the vehicle is identified as being parked or starting, two methods for visual perception and display using electronic exterior rearview mirrors are formed based on whether the vehicle is in a parking area. This covers possible environmental scenarios when the vehicle is parked or starting. When the vehicle is in a parking area, the surrounding spatial information is detected as the display content of the electronic exterior rearview mirror, enabling the driver to cope with the complex environment of the parking area and reducing the impact of blind spots on the driver. When the vehicle is not in a parking area, the driving environment is relatively simpler than in a parking area. Environmental information from the left and right side rearview cameras can be obtained as the display content of the electronic exterior rearview mirror. Moreover, the environmental information collected by the left and right side rearview cameras can be directly transmitted to the electronic exterior rearview mirror controller, resulting in higher data transmission efficiency and significantly reducing display latency to cope with rapidly changing conditions around the vehicle. Thus, based on the surrounding scene when the vehicle is parked or starting, the corresponding information required by the electronic exterior rearview mirror is obtained from the environmental data collected by the vehicle's existing sensors, providing data support for the electronic exterior rearview mirror display, realizing intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying the vehicle architecture.

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

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

[0013] Alternatively, based on the detection result, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror. After receiving the environmental information, the data transmission unit processes the environmental information and sends the processing result to the data transmission unit, so that the data transmission unit can send the processing result to the electronic rearview mirror.

[0014] Through the above technical solution, when the vehicle is in a parking area, environmental information can be sent to the electronic rearview mirror in two ways: one is to forward the environmental information directly through the data transmission unit, and the other is to forward the environmental information after processing by the data transmission unit. Thus, different data transmission methods can be used for different actual environments of the vehicle and different sensors, which improves data transmission efficiency, reduces vehicle costs, simplifies vehicle architecture, and has a wider range of applications.

[0015] In combination 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 surrounding spatial information 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 detection result indicates that the vehicle's rear has reached a preset physical blockade condition, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the vehicle's left and right front-view cameras to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller; the left and right front-view cameras are one of the sensors included in the intelligent driving system.

[0017] Through the above technical solution, when the vehicle is in a parking area, the appropriate sensors, namely the left and right front-view cameras, can be selected to collect environmental information based on the physical obstruction behind the vehicle. This eliminates the need to collect invalid environmental information behind the vehicle, making the display content of the electronic rearview mirror more in line with the driver's driving needs. It improves the reliability of the function while making effective use of vehicle resources, realizes intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0018] In combination 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 surrounding spatial information to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror includes:

[0019] When the detection result indicates that the rear of the vehicle has reached the first preset movement space condition, the control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right rearview cameras of the vehicle to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller; the left and right rearview cameras are one of the sensors included in the intelligent driving system.

[0020] Through the above technical solution, when the vehicle is in a parking area, appropriate sensors, namely left and right rearview cameras, can be selected to collect environmental information when there is a certain amount of space behind the vehicle. This allows the driver to drive the vehicle into or out of the parking space based on the rear environment, making the display content of the electronic rearview mirror more in line with the driver's driving needs. This improves the reliability of the function while making effective use of vehicle resources, realizes intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0021] In combination 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 surrounding spatial information 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 detection result indicates that the vehicle is on the side and both sides meet the second preset movement space condition, 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 side rearview cameras of the vehicle to the electronic side rearview mirror in sequence through the data transmission unit and the electronic side rearview mirror controller; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0023] Through the above technical solution, when the vehicle is in a parking area, appropriate sensors, namely left and right side rearview cameras, can be selected to collect environmental information when there is movement space on both sides of the vehicle. This allows the driver to drive the vehicle into or out of the parking space based on the left, right, and rear environment, making the display content of the electronic rearview mirror more in line with the driver's driving needs. This improves the reliability of the function while making effective use of vehicle resources, realizes intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0024] In conjunction with the first aspect and the above implementation methods, in some possible implementation methods, the step of sending a control signal to the data transmission unit based on the detection result to control the data transmission unit to send the environmental information sent by the sensor to the electronic exterior rearview mirror, and after receiving the environmental information through the data transmission unit, processing the environmental information and sending the processing result to the data transmission unit, so that the data transmission unit can send the processing result to the electronic exterior rearview mirror, includes:

[0025] When the detection result indicates that the vehicle's side or any side meets the third preset movement space condition, 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 moving side corresponding to the side of the vehicle that meets the third preset movement space condition to the electronic exterior rearview mirror via the data transmission unit and the electronic exterior rearview mirror controller; the side rearview camera is one of the sensors included in the intelligent driving system; and after receiving the environmental information collected by the surround view camera on the non-moving side of the vehicle opposite to the moving side through the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic exterior rearview mirror via the data transmission unit via 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.

[0026] Through the above technical solution, when the vehicle is in a parking area, appropriate sensors can be selected based on the situation where there is movement space on one side of the vehicle. Specifically, a side-view camera is used on the moving side, and a surround-view camera is used on the non-moving side to collect environmental information. This allows the driver to drive the vehicle into or out of the parking space based on the available space on the moving side and the blind spots on the non-moving side. This makes the display content of the electronic rearview mirror more in line with the driver's driving needs. Furthermore, different data transmission methods are adopted based on the selected sensors, which improves the reliability of the function while making effective use of vehicle resources. This enables intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0027] In combination with the first aspect and the above implementation methods, in some possible implementation methods, before determining whether the vehicle is in the parking area, the method further includes:

[0028] Detect whether the vehicle meets the preset parking and starting conditions;

[0029] When the vehicle is detected to meet the preset parking and starting conditions, it is determined that the vehicle is in the parking or starting scenario.

[0030] The above technical solution ensures that the vehicle is locked by the brakes after entering the parking mode, reducing unnecessary slippage during driving. It also ensures a smooth start and operation of the vehicle after entering the starting scenario. Furthermore, the vehicle is only controlled to perform environmental detection when the preset parking and starting conditions are met, avoiding ineffective waste of resources and preventing invalid functions from consuming other functional resources, thereby affecting the driver's driving experience.

[0031] 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:

[0032] The judgment module is used to determine whether the vehicle is in a parking area when the vehicle is detected to be in a parking or starting scenario.

[0033] The control module is used to detect the surrounding space information of the vehicle when it is in the parking area, obtain the detection result, and control the transmission path of the environmental information corresponding to the detection result so that the environmental information is transmitted to the electronic exterior rearview mirror for display according to the transmission path; wherein the environmental information is collected by the sensor; when it is not in the parking area, the control module controls the data transmission unit to directly transmit the environmental information collected by the left and right rearview cameras of the vehicle to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror; the left and right rearview cameras are one of the sensors included in the intelligent driving system.

[0038] The third control unit is used to send the control signal to the data transmission unit when the detection result indicates that a preset physical blockage condition has been reached behind the vehicle, so as to control the data transmission unit to send the environmental information collected by the left and right front-view cameras of the vehicle to the electronic rearview mirror in sequence through the data transmission unit and the electronic rearview mirror controller; the left and right front-view cameras are one of the sensors included in the intelligent driving system.

[0060] Figure 11 This is a structural schematic diagram of a vehicle provided according to an embodiment of this application. Detailed Implementation

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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 simultaneously collect environmental information in four directions: front, rear, left, and right of the vehicle.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] The transmission path can be, but is not limited to, two types of paths:

[0071] 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 does not go through intelligent driving controller 13, thus improving display efficiency and timeliness.

[0072] 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.

[0073] 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.

[0074] Figure 7 This is a schematic flowchart illustrating a display method for an electronic exterior rearview mirror provided in an embodiment of this application.

[0075] For example, such as Figure 7 As shown, this method is applied to the intelligent driving system of a vehicle and includes the following steps:

[0076] In step S701, when the vehicle is identified as being in a parking or starting scenario, it is determined whether the vehicle is in a parking area.

[0077] It is understandable that when a vehicle is in a parking or starting scenario, its state can be parking, parking out of a parking space, waiting for a traffic light, or starting on a green light. For different states, parking or starting scenarios can occur in corresponding locations, such as parking lots, traffic light intersections, or the side of a road where temporary parking is required. Therefore, this application embodiment can determine whether the vehicle is in a parking area when it is identified as being in a parking or starting scenario. This can be done by using sensor devices to sense whether the surrounding environment is a parking area or by obtaining the current location through positioning information to determine whether the vehicle is in a parking area. Based on the different locations of the vehicle, the corresponding display content of the electronic rearview mirror can be generated.

[0078] For example, it can be combined Figure 8 and Figure 9 As shown, high-precision positioning and map recognition information are used to determine the vehicle's location and obtain information about the surrounding environment. For example... Figure 8As shown, the vehicle's current location information can be obtained through the intelligent driving high-precision positioning function. Specifically, the vehicle's location information is obtained using GNSS (Global Navigation Satellite System) and other related technologies. This information is received by the vehicle's TBOX and the positioning algorithm determines the vehicle's location, resulting in the final positioning result. The intelligent driving high-precision map function provides the vehicle map information required by the intelligent driving system, helping to understand the surrounding environment and assisting users in end-to-end intelligent driving control, allowing for advance access to road information ahead. Road environment information can be obtained through intelligent driving sensor functions. These 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. The vehicle's power controller can transmit the vehicle's ignition status and gear information in real time, thereby obtaining the vehicle's current location and navigation information, and providing support for determining whether the vehicle is in an open road or parking lot scenario based on its current location.

[0079] The method for identifying whether a vehicle is in a parked or starting state will be described below.

[0080] Optionally, in some embodiments, before determining whether the vehicle is in a parking area, the method further includes: detecting whether the vehicle meets preset parking and starting conditions; and when the vehicle meets the preset parking and starting conditions, determining that the vehicle is in a parking or starting scenario.

[0081] Here, we will explain the methods for identifying whether a vehicle is in a parked or starting situation.

[0082] In actual operation, it is checked whether the vehicle meets the preset parking start conditions. The preset parking start conditions may include the vehicle speed being 0 and the gear being shifted to parking or the EPB (Electrical Park Brake) being engaged, as well as the gear being shifted from parking to non-parking or the EPB being released.

[0083] Furthermore, in this embodiment of the application, after detecting that the vehicle meets the preset parking and starting conditions, it can determine whether the vehicle is in a parking or starting scenario.

[0084] The above technical solution ensures that the vehicle is locked by braking after entering the parking condition, reducing unnecessary slippage during driving. It also ensures a smooth start and operation of the vehicle after entering the starting scenario. Furthermore, the electronic exterior rearview mirrors are controlled to display only when the vehicle meets the preset parking and starting conditions, avoiding ineffective waste of resources and preventing invalid functions from occupying other functional resources, thereby affecting the driver's driving experience.

[0085] In step S702, if the vehicle is in a parking area, the surrounding space information is detected to obtain the detection result. Based on the detection result, the transmission path of the environmental information corresponding to the detection result is controlled so that the environmental information is transmitted to the electronic rearview mirror for display. The environmental information is collected by sensors.

[0086] In some embodiments, when the vehicle is in a parking or starting scenario and is in a parking area such as a parking lot, there may be many obstacles around the vehicle. In this case, the embodiments of this application can use sensors to detect the spatial information around the vehicle to obtain the distribution of obstacles around the vehicle. Then, according to the distribution of obstacles around the vehicle, the corresponding environmental information transmission path is selected. The level of intelligence is high, which can realize the effective utilization of the vehicle's resources. The environmental information is displayed through the electronic exterior rearview mirror, which can more intuitively show the available space when the vehicle performs parking or starting actions, avoid collisions, and eliminate the need to add an additional rearview camera. This further simplifies the architecture of the electronic exterior rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0087] Optionally, in some embodiments, controlling the transmission path of environmental information corresponding to the detection result based on the detection result includes: sending a control signal to the data transmission unit based on the detection result to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror; or, sending a control signal to the data transmission unit based on the detection result to control the data transmission unit to send the environmental information sent by the sensor to the electronic rearview mirror, and after receiving the environmental information through the data transmission unit, 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] In other words, the embodiments of this application can determine the data source based on the detection results, i.e. the distribution of obstacles around the vehicle, and thus determine the signal transmission method, i.e., the signal transmission link.

[0089] Signal transmission links can be divided into two types:

[0090] The environmental information collected by the sensor is sent to the data transmission unit, which then sends the environmental information directly to the electronic rearview mirror, i.e., using the bypass link of transmission path 1.

[0091] The environmental information collected by the sensor is sent to the data transmission unit. After receiving the environmental information, the data transmission unit sends the processing result of the environmental information to the electronic rearview mirror controller. After receiving the environmental information, the electronic rearview mirror controller processes the environmental information and sends 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, that is, using the SOC link of transmission path 2.

[0092] Furthermore, the selection of transmission links in this application embodiment based on different detection results will be described in detail below.

[0093] Therefore, when the vehicle is in a parking area, the embodiments of this application can send environmental information to the electronic rearview mirror through at least one path. One path is to directly forward the environmental information through the data transmission unit, and the other path is to forward the environmental information after processing by the data transmission unit. Thus, different data transmission methods can be used for different actual environments of the vehicle and different sensors, thereby improving data transmission efficiency, reducing vehicle costs, simplifying vehicle architecture, and having a wider range of applications.

[0094] Optionally, in some embodiments, based on the surrounding spatial information, 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 detection result indicates that a preset physical blockage condition has been reached behind 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 left and right front-view cameras of the vehicle to the electronic exterior rearview mirror in sequence through the data transmission unit and the electronic exterior rearview mirror controller; the left and right front-view cameras are one of the sensors included in the intelligent driving system.

[0095] Here, the signal transmission link selected in this application embodiment is described when the detection result indicates that the rear of the vehicle has reached a certain physical blockade condition.

[0096] When there is a physical blockage behind the vehicle, i.e., there is a static obstacle behind the vehicle and the vehicle is in a parking area rather than on a public road, the vehicle does not need to reverse. At this time, the environment behind the vehicle has little impact on the driver's control of the vehicle to perform parking or starting actions. In this case, the embodiments of this application can reuse the left and right front-view cameras in the intelligent driving system and use the electronic exterior rearview mirrors to display the left, right and front environmental information of the vehicle, thereby assisting the driver in controlling the vehicle to perform parking or starting actions.

[0097] Therefore, the embodiments of this application can use the left and right side rearview cameras of the vehicle to obtain the surrounding environment information of the vehicle, and transmit the environmental information collected by the left and right side rearview cameras directly to the electronic exterior rearview mirror controller through the data transmission unit, so that the electronic exterior rearview mirror can display the environmental information collected by the left and right side frontview cameras, thereby increasing the safety of the driver when parking or starting, and providing the driver with a field of vision on the left, right and front sides of the vehicle, assisting the driver in controlling the vehicle to perform parking or starting actions.

[0098] Based on the aforementioned transmission link, this application embodiment can select appropriate sensors, namely left and right front-view cameras, as the data source for collecting environmental information when there is physical obstruction behind the vehicle. This eliminates the need to collect invalid environmental information behind the vehicle, making the display content of the electronic rearview mirror more in line with the driver's driving needs. It improves the reliability of the function while making effective use of vehicle resources, realizes intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0099] It should be noted that the preset physical blocking conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0100] Optionally, in some embodiments, based on the surrounding spatial information, 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 detection result indicates that the rear of the vehicle has reached a first preset moving space condition, 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 side rearview cameras of the vehicle to the electronic exterior rearview mirror sequentially through the data transmission unit and the electronic exterior rearview mirror controller; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0101] Here, the signal transmission link selected in this application embodiment is described when the detection result indicates that a certain amount of movement space has been reached behind the vehicle.

[0102] When there is space to move behind the vehicle, if the driver intends to control the vehicle to perform parking or starting actions, the driver's vision is focused on the front of the vehicle and it is difficult to obtain the actual environmental information behind the vehicle. Therefore, it is necessary to obtain the rear view of the vehicle. At this time, the embodiments of this application can reuse the left and right rear-view cameras in the intelligent driving system as sensors to obtain the environmental information on the left and right sides and the rear of the vehicle to supplement the driver's vision.

[0103] In this embodiment, the environmental information collected by the left and right rearview cameras can be sequentially sent to the electronic rearview mirror through the data transmission unit and the electronic rearview mirror controller, so that the electronic rearview mirror can display the environmental information collected by the left and right rearview cameras, thereby increasing the safety of the driver when parking or starting, and providing the driver with a field of vision to the left, right and rear of the vehicle, assisting the driver in controlling the vehicle to park or start. The first preset moving space condition is that there is moving space behind the vehicle. The specific value of the moving space can be set by those skilled in the art according to factors such as vehicle size.

[0104] Based on the aforementioned transmission link, this application embodiment can select appropriate sensors, namely left and right side rearview cameras, to collect environmental information when there is a certain amount of movement space behind the vehicle. This allows the driver to drive the vehicle into or out of the parking space based on the rear environment, making the display content of the electronic rearview mirror more in line with the driver's driving needs. This improves the reliability of the function while making effective use of vehicle resources, realizes intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0105] Optionally, in some embodiments, based on the surrounding spatial information, 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 detection result indicates that the vehicle is to the side and both sides meet the second preset moving space condition, 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 side rearview cameras of the vehicle to the electronic exterior rearview mirror sequentially through the data transmission unit and the electronic exterior rearview mirror controller; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0106] Here, the signal transmission link selected in this application embodiment is described when the detection result is that the vehicle is to the side and both sides have reached a certain movement space condition.

[0107] When there is room for movement on both sides of the vehicle, if the driver intends to control the vehicle to perform parking or starting actions, the driver's focus is on the front of the vehicle. Therefore, it is necessary to obtain the field of vision on both sides of the vehicle. In this case, the embodiments of this application can reuse the left and right rearview cameras in the intelligent driving system as sensors to obtain environmental information on the left, right and rear sides of the vehicle to supplement the driver's field of vision.

[0108] In this embodiment, the environmental information collected by the left and right rearview cameras can be sequentially sent to the electronic rearview mirror through the data transmission unit and the electronic rearview mirror controller, so that the electronic rearview mirror can display the environmental information collected by the left and right rearview cameras, thereby increasing the safety of the driver when parking or starting, and providing the driver with a field of vision to the left, right and rear of the vehicle, assisting the driver in controlling the vehicle to park or start. The second preset moving space condition is that there is moving space behind the vehicle. The specific value of the moving space can be set by those skilled in the art according to factors such as vehicle size.

[0109] Based on the aforementioned transmission link, this application embodiment can select appropriate sensors, namely left and right side rearview cameras, to collect environmental information when there is movement space on both sides of the vehicle. This allows the driver to drive the vehicle into or out of the parking space based on the left, right, and rear environment, making the display content of the electronic exterior rearview mirror more in line with the driver's driving needs. This improves the reliability of the function while making effective use of vehicle resources, realizes intelligent interaction between the electronic exterior rearview mirror and the environment, further simplifies the architecture of the electronic exterior rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0110] Optionally, in some embodiments, based on the detection results, 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. After receiving the environmental information, the data transmission unit processes the environmental information and sends the processing result to the data transmission unit, so that the data transmission unit can send the processing result to the electronic exterior rearview mirror. This includes: when the detection result indicates that the vehicle is to the side and either side meets a third preset moving space condition, 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 moving side corresponding to the side of the vehicle that meets the third preset moving space condition to the electronic exterior rearview mirror sequentially through the data transmission unit and the electronic exterior rearview mirror controller; the side rearview camera is one of the sensors included in the intelligent driving system; and after receiving the environmental information collected by the surround view camera on the non-moving side of the vehicle opposite to the moving side 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.

[0111] Here, the signal transmission link selected in this application embodiment is described when the detection result is the side of the vehicle and either side reaches a certain movement space condition.

[0112] When there is only one side of the vehicle with movement space, if the driver intends to control the vehicle to perform parking or starting actions, the driver's line of sight is often focused on the moving side with movement space and in front of the moving side. Therefore, the moving side corresponding to either side that meets the third preset movement space condition needs to obtain the side and rear view of the vehicle, while the non-moving side without movement space needs to obtain the surround view to supplement the driver's field of vision. At this time, the embodiments of this application can reuse the left or right rearview camera and the surround view camera in the intelligent driving system as sensors to obtain environmental information of the driver's blind spot.

[0113] For example, when a vehicle is in a parking lot and is parked, if the distance between one side of the vehicle and the vehicle in the adjacent parking space is small, and the adjacent parking space on the other side is not occupied, then if the distance between one side of the vehicle and the vehicle in the adjacent parking space causes the movement space on one side of the vehicle to not meet the third preset movement space condition, then one side of the vehicle is the non-moving side; since the adjacent parking space on the other side is not occupied, and no other obstacles are detected near the other side, it can be concluded that the other side of the vehicle meets the third preset movement space condition, and this other side is the moving side.

[0114] This application embodiment can sequentially transmit environmental information collected by the left or right rearview cameras to the electronic rearview mirror via a data transmission unit and an electronic rearview mirror controller, enabling the electronic rearview mirror to display the environmental information collected by the left and right rearview cameras. This application embodiment can also process the environmental information collected by the surround-view cameras and transmit the processing results sequentially to the electronic rearview mirror via the intelligent driving controller, the data transmission unit, and the electronic rearview mirror controller, thereby increasing the safety of the driver when parking or starting the vehicle. This provides the driver with a field of vision to the left, right, and rear of the vehicle, assisting the driver in controlling the vehicle to park or start the vehicle. The third preset moving space condition is that there is moving space behind the vehicle. The specific value of the moving space can be set by those skilled in the art according to factors such as vehicle size.

[0115] Based on the aforementioned transmission link, this application embodiment can select appropriate sensors for situations where there is movement space on the side of the vehicle and only one side. Specifically, a side rearview camera is selected on the moving side, and a surround view camera is selected on the non-moving side to collect environmental information. This allows the driver to drive the vehicle into or out of the parking space based on the available space on the moving side and the blind spots on the non-moving side. This makes the display content of the electronic rearview mirror more in line with the driver's driving needs. Furthermore, different data transmission methods are adopted based on the selected sensors, which improves the reliability of the function while making effective use of vehicle resources. This enables intelligent interaction between the electronic rearview mirror and the environment, further simplifies the architecture of the electronic rearview mirror, reduces vehicle costs, and saves vehicle resources.

[0116] In summary, the embodiments of this application can select the corresponding transmission link based on different detection results. The sensor strategies and controller control selected based on different parking and starting scenarios are shown in Table 1. Table 1 is a strategy selection table for different detection results.

[0117] Table 1

[0118]

[0119] In actual execution, as shown in Table 1, this application embodiment can collect environmental information using the left rear-view camera when the surrounding scene is a moving space behind the vehicle that meets the first preset condition. At this time, the serializer can be controlled to output data from the left and right rear-view cameras via the bypass link.

[0120] In this embodiment of the application, when there is a moving space on both sides of the vehicle that meets the second preset condition, the environmental information can be collected by the left rear-view camera. At this time, the serializer can be controlled to output the data of the left and right rear-view cameras by bypassing the link.

[0121] In this embodiment of the application, when the surrounding scene is a moving space that meets the third preset condition on the side of the vehicle, the side-view camera is used to collect the environmental information on the moving side and the surround-view camera is used to collect the environmental information on the non-moving side. At this time, when the side-view camera data of the moving side is obtained, the serializer is controlled to output the bypass link of the side-view camera data of the moving side. When the surround-view camera data of the non-moving side is obtained, the serializer is controlled to output the SOC link of the surround-view camera data of the non-moving side.

[0122] In step S703, if the vehicle is not in a parking area, the control data transmission unit directly transmits the environmental information collected by the left and right side rearview cameras to the electronic exterior rearview mirror controller for display on the electronic exterior rearview mirror; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0123] In other embodiments, when the vehicle is in a parking or starting scenario and is not in a parking area, it can be determined that the vehicle is currently on a public road. At this time, the vehicle may be waiting at a traffic light, temporarily parked in an emergency lane, or starting at a traffic light intersection. In this situation, the area where the vehicle is located has a wide field of vision and few obstacles in front. The driver can obtain the road conditions in front of the vehicle through the windshield. Therefore, the embodiments of this application can use the left and right rearview cameras of the vehicle to obtain the surrounding environment information of the vehicle, and transmit the environmental information collected by the left and right rearview cameras directly to the electronic exterior rearview mirror controller through the data transmission unit, thereby providing the driver with the left, right and rear views of the vehicle and assisting the driver in controlling the vehicle to perform parking or starting actions.

[0124] Among them, since the environmental information collected by the left and right rearview cameras can be directly transmitted to the electronic rearview mirror controller through the data transmission unit and displayed on the electronic rearview mirror, the environmental information transmission speed is faster and the display screen of the electronic rearview mirror has lower latency. This makes it more suitable for public roads with complex and ever-changing road conditions, thereby increasing the safety of drivers when parking or starting.

[0125] In summary, this application enables two methods for visual perception and display using electronic exterior rearview mirrors, based on whether the vehicle is in a parking area or not, when the vehicle is detected to be in a parking or starting scenario. This covers possible environmental scenarios when the vehicle is in a parking or starting situation. When the vehicle is in a parking area, the surrounding spatial information is detected as the display content of the electronic exterior rearview mirror, allowing the driver to cope with the complex environment of the parking area and reducing the impact of blind spots on the driver. When the vehicle is not in a parking area, the driving environment is relatively simpler than in a parking area. Environmental information from the left and right side rearview cameras can be obtained as the display content of the electronic exterior rearview mirror. Moreover, the environmental information collected by the left and right side rearview cameras can be directly transmitted to the electronic exterior rearview mirror controller, resulting in higher data transmission efficiency and significantly reducing display latency to cope with rapidly changing vehicle surroundings. Thus, based on the surrounding scene when the vehicle is parked or starting, the application obtains the information required by the electronic exterior rearview mirror from the environmental data collected by the vehicle's existing sensors, providing data support for the electronic exterior rearview mirror display, realizing intelligent interaction between the electronic exterior rearview mirror and the environment, reducing vehicle costs, and simplifying vehicle architecture.

[0144] In summary, this application enables two methods for visual perception and display using electronic exterior rearview mirrors, based on whether the vehicle is in a parking area or not, when the vehicle is detected to be in a parking or starting scenario. This covers possible environmental scenarios when the vehicle is in a parking or starting situation. When the vehicle is in a parking area, the surrounding spatial information is detected as the display content of the electronic exterior rearview mirror, allowing the driver to cope with the complex environment of the parking area and reducing the impact of blind spots on the driver. When the vehicle is not in a parking area, the driving environment is relatively simpler than in a parking area.

Moreover, the environmental information collected by the left and right side rearview cameras can be directly transmitted to the electronic exterior rearview mirror controller, resulting in higher data transmission efficiency and significantly reducing display latency to cope with rapidly changing vehicle surroundings.
