[0071] 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.

[0072] 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.

[0073] 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.

[0074] Regarding existing electronic exterior rearview mirrors (Camera Monitor System, CMS), firstly, as... Figures 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.

[0075] Secondly, since the electronic outside rearview mirror only has a single side view angle, there are many blind spots that cannot be identified. In order to solve this problem, as shown in Figure 4 , the rearview mirror is usually equipped with no less than 8 visible light cameras to simultaneously collect environmental information in the front, rear, left and right directions of the vehicle.

[0076] Therefore, the electronic outside rearview mirror in the related art needs to be equipped with a separate controller and camera, which leads to a complex and redundant system architecture of the electronic outside rearview mirror, low utilization rate of vehicle devices, difficulty in maximizing the integration of the electronic outside rearview mirror system and the vehicle sensor, and low utilization of vehicle resources, making the vehicle structure more complex and the cost higher.

[0077] Next, the application scenarios or system architecture of the embodiments of the present application will be described. Referring to Figure 5 , the vehicle includes an intelligent driving system 10 and an electronic outside rearview system 20. The intelligent driving system 10 includes a sensor 11, a data transmission unit 12 and an intelligent driving controller 13, and the electronic outside rearview system 20 is different from the electronic outside rearview mirror in the related art, and only has an electronic outside rearview mirror controller 21 and an electronic outside rearview mirror 22. The sensor 11 is used to collect environmental information, and the data transmission unit 12 is used to transmit the environmental information from the sensor 11 to the intelligent driving controller 13 and the electronic outside rearview mirror controller 21. The intelligent driving controller 13 can control the data transmission unit 12 to directly transmit the environmental information collected by the sensor 11 or transmit the environmental information processed by the intelligent driving controller 13 to the electronic outside rearview mirror controller 21, in addition to performing the corresponding intelligent driving control strategy according to the environmental information collected by the sensor 11. Thus, the electronic outside rearview mirror controller 21 processes the information, so that the electronic outside rearview mirror 22 displays accordingly.

[0078] As a possible implementation, as shown in Figure 6 , the sensor 11 can include but is not limited to a side-view camera 111 and an around-view camera 112. The side-view camera 111 can include but is not limited to a side-front-view camera and a side-rear-view camera, so as to collect corresponding side-front-view camera information and side-rear-view camera information as environmental information.

[0079] In addition, as a possible implementation, as shown in Figure 6As shown, the camera includes a corresponding serializer in addition to the corresponding sensor 11 to serially process the information, and the data transmission unit 12 includes a corresponding deserializer and serializer (as shown by deserializer 121, deserializer 123 and serializer 122) to deserially process the information collected by the sensor 11, and the serializer 122 serially processes the information sent by the deserializer 121 or the information sent by the intelligent driving controller 13, and sends the information to the deserializer 23 of the electronic outside rearview system 20 for deserial processing, and finally the electronic outside rearview mirror 22 displays the deserialized information under the control of the electronic outside rearview mirror controller 21.

[0080] The transmission path can be, but is not limited to, divided into two paths:

[0081] Transmission path 1: After the environmental information collected by the side-view camera 111 of the sensor 11 is serially processed, it is transmitted to the deserializer 121 of the data transmission unit 12 through the signal transmission line, the deserializer 121 of the data transmission unit 12 sends the deserialized data to the serializer 122 of the data transmission unit 12, and after receiving the transmission instruction of the intelligent driving controller 13, the serializer 122 sends the information to the electronic outside rearview mirror 22, i.e. using the bypass link, so that the information does not pass through the intelligent driving controller 13, thereby improving the display efficiency and timeliness.

[0082] Transmission path 2: After the environmental information collected by the surround-view camera 112 of the sensor 11 is serially processed, it is transmitted to the deserializer 123 of the data transmission unit 12 through the signal transmission line, the deserializer 123 of the data transmission unit 12 sends the deserialized data to the intelligent driving controller 13, the intelligent driving controller 13 sends the result obtained by processing the information to the serializer 122, and the serializer 122 sends the information to the electronic outside rearview mirror 22, i.e. using the SOC link, without the bypass link interface, without the need to additionally increase the serializer, thereby reducing the display cost.

[0083] In summary, since the data transmission unit 12 of the intelligent driving system 10 has a serializer 122, and the serializer 122 has only one bypass interface, the bypass link has only one, without changing the architecture, ensuring the timeliness of the data, the embodiment of the application can choose to transmit the related environmental information of the side view of more application scenarios through the bypass link, especially considering that the electronic outside rearview mirror mainly replaces the physical outside rearview mirror, the field of view mainly aims at the rear distance of the vehicle, and the field of view of the side view is most similar. At the same time, the bypass link is fast and can meet the timeliness requirement. If the related environmental information of the surround view is also transmitted through the bypass link, an additional serializer needs to be added, resulting in increased cost. Therefore, the related environmental information of the surround view can be transmitted through the SOC link to reduce cost and simplify the architecture. However, the specific implementation mode can be various, such as transmitting the related environmental information of the surround view through the SOC link and transmitting the related environmental information of the side view through the bypass link. The specific mode can be set by a person skilled in the art according to the actual situation, and is not limited here.

[0084] Figure 7 is a schematic flowchart of a display method of an electronic outside rearview mirror provided by the embodiment of the application.

[0085] For example, as shown in Figure 7 the method is applied to an intelligent driving controller of a vehicle, and includes the following steps:

[0086] In step S701, when it is identified that the vehicle is in a driving meeting condition, the meeting space between the vehicle and an oncoming vehicle is detected according to the oncoming vehicle, or the actual speed of the vehicle is obtained.

[0087] It can be understood that vehicle meeting is a common traffic scene on the road, and vehicle meeting can be formed when two vehicles meet. The embodiment of the application can obtain the surrounding environment of the vehicle through sensors such as infrared sensors, surround view cameras, side view cameras and the like in the intelligent driving system, obtain the current position of the vehicle through positioning information, obtain the current speed of the vehicle through the intelligent driving system, and the like, so as to comprehensively identify the current condition of the vehicle through the surrounding environment of the vehicle, the current position of the vehicle and the current speed of the vehicle and the like, and further determine whether the vehicle is in a driving meeting condition.

[0088] During driving, the meeting condition is an important test for the driver. When the vehicles meet, the driver needs to pay special attention to the following aspects:

[0089] Pay attention to the speed: when the vehicles meet, in order to maintain driving safety, the driver needs to control the speed within a suitable range according to the road conditions and the line of sight distance. If the speed is too fast, it may lead to loss of control and danger.

[0090] Keep a safe distance: when meeting, it is necessary to keep a safe distance with the oncoming vehicle, so as to have enough time to react in case of emergency.

[0091] Determine the intersection of vehicles: when meeting, the driver needs to determine the intersection of vehicles at the place where the oncoming vehicle arrives, keep the vehicle driving line stable, and avoid dangerous interweaving.

[0092] Therefore, the embodiments of the present application can ensure the safety of driving when the vehicle is in the driving meeting condition, and the driver needs to pay close attention to the road conditions and the state of the oncoming vehicle, reasonably control the vehicle speed, keep a safe distance, and determine the intersection of vehicles.

[0093] Therefore, the embodiments of the present application can identify the meeting condition, detect the meeting space between the vehicle and the oncoming vehicle according to the oncoming vehicle, or obtain the actual vehicle speed, so as to determine the data source and display content of the electronic outside rearview mirror, thereby assisting the driver to reasonably control the vehicle speed and keep a safe distance.

[0094] For example, the embodiments of the present application can use at least one surround view camera and side view camera in the intelligent driving system to collect surround view camera data and side view camera data, process the video picture by using computer vision technology based on the collected surround view or side view environmental data, identify the meeting space by using deep learning algorithm, and calculate the meeting speed of the vehicle at this time.

[0096] In step S702, the first transmission path of the environmental information corresponding to the meeting space is controlled according to the meeting space, or the second transmission path of the environmental information corresponding to the actual vehicle speed is controlled according to the actual vehicle speed, so that the environmental information is transmitted to the electronic outside rearview mirror according to the first transmission path or the second transmission path for display; wherein the environmental information is collected by a sensor.

[0097] In actual implementation, the embodiment of the application can determine the data source of the environmental information and the transmission path of the environmental information according to the meeting space and the actual vehicle speed, so as to select different sensors for different situations, and then transmit the environmental information to the electronic outside rearview mirror through the transmission path corresponding to the sensor, so as to provide the driver with an auxiliary field of view that meets the driving needs of the driver, improve the information transmission efficiency, simplify the architecture of the electronic outside rearview mirror, reduce the cost of the vehicle, and simplify the architecture of the vehicle, wherein the meeting space can be, but is not limited to, the space between the vehicle and the oncoming vehicle when the two vehicles are driving in opposite directions, and the actual vehicle speed can be, but is not limited to, the driving speed of the vehicle when the vehicle and the oncoming vehicle are driving in opposite directions.

[0098] It should be noted that the first transmission path and the second transmission path will be described in detail below.

[0099] Optionally, in some embodiments, the first transmission path of the environmental information corresponding to the meeting space is controlled according to the meeting space, comprising: if the meeting space is greater than the preset space, a first 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 outside rearview mirror; if the meeting space is less than or equal to the preset space, it is judged whether there is a collision object that can collide with the vehicle on the non-meeting side of the vehicle; if there is no collision object that can collide with the vehicle, a first 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 outside rearview mirror, or the environmental information is processed after being received by the data transmission unit, and the processing result is sent to the data transmission unit to send the processing result to the electronic outside rearview mirror through the data transmission unit; if there is a collision object that can collide with the vehicle, the environmental information is processed after being received by the data transmission unit, and the processing result is sent to the data transmission unit to send the processing result to the electronic outside rearview mirror through the data transmission unit.

[0100] Here, the first transmission path is described in detail.

[0101] The embodiment of the application can consider that the vehicle and the meeting vehicle are always in a safe distance when the meeting space is greater than the preset space, so it is not necessary to obtain too detailed space environmental information, the left and right side rearview cameras in the intelligent driving system can be reused as sensors to obtain the environmental information of the left side, the right side and the rear of the vehicle, and the content is displayed through the electronic outside rearview mirror, so as to complete the field of view of the driver. At this time, the transmission link can be that the environmental information is collected by the left and right side rearview cameras of the vehicle, and the environmental information is transmitted to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn by the data transmission unit.

[0102] The embodiment of the present application can determine whether there is a collision object that may collide with the vehicle on the non-passing side of the vehicle in the case that the passing space is less than or equal to the preset space, so as to use the corresponding sensor and signal transmission link based on the environmental state of the non-passing side. The collision object that may collide with the vehicle can be a moving target obstacle or a stationary target obstacle, and the moving target obstacle can include but is not limited to a car, a pedestrian, a bicycle, a motorcycle, a tricycle, and the like, and the stationary target obstacle can include but is not limited to a railing, a water horse, a cone barrel, a wall, and the like. The preset space can be set by a person skilled in the art, and is not specifically limited here.

[0103] When there is no collision object that may collide with the vehicle on the non-passing side, the signal transmission link can be divided into two types:

[0104] The environmental information collected by the sensor is sent to the data transmission unit, and the data transmission unit directly sends the environmental information to the electronic outside rearview mirror, that is, the bypass link of the transmission path 1 is used.

[0105] The environmental information collected by the sensor is sent to the data transmission unit, and the data transmission unit sends the processing result of the environmental information to the electronic outside rearview mirror controller after receiving the environmental information, and processes the environmental information after the electronic outside rearview mirror controller receives the environmental information, and sends the processing result to the data transmission unit, so as to send the processing result to the electronic outside rearview mirror through the data transmission unit, that is, the SOC link of the transmission path 2 is used.

[0106] When there is a collision object that may collide with the vehicle on the non-passing side, the signal transmission link can be: the environmental information collected by the sensor is sent to the data transmission unit, and the data transmission unit sends the processing result of the environmental information to the electronic outside rearview mirror controller after receiving the environmental information, and processes the environmental information after the electronic outside rearview mirror controller receives the environmental information, and sends the processing result to the data transmission unit, so as to send the processing result to the electronic outside rearview mirror through the data transmission unit, that is, the SOC link of the transmission path 2 is used.

[0107] It should be noted that the selection of the transmission link of the embodiment of the present application will be described in detail below.

[0108] Therefore, in the case that the passing space is less than or equal to the preset space, based on whether there is a collision object that may collide with the vehicle on the non-passing side of the vehicle, the embodiment of the present application can select different data transmission links based on different sensors and environmental information, improve the data transmission efficiency, improve the practicality of the device of the vehicle, reduce the cost of the vehicle, simplify the architecture of the vehicle, and have a wider application range.

[0109] Optionally, in some embodiments, the first 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 outside rearview mirror, or 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 to send the processing result to the electronic outside rearview mirror through the data transmission unit, comprising: sending the first control signal to the data transmission unit to control the data transmission unit to send the environmental information collected by the side rearview camera on the non-passing side of the vehicle to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn; the side rearview camera is one of the sensors included in the intelligent driving system; after receiving the environmental information collected by the surround view camera on the passing side of the vehicle through the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic outside rearview mirror through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror in turn; the surround view camera is one of the sensors included in the intelligent driving system.

[0110] Here, when there is no collision object on the non-passing side that may collide with the vehicle, the signal transmission link selected by the embodiment of the application is described.

[0112] For the passing side, due to the complexity and variability of the environment, at this time, the embodiment of the application can reuse the surround view camera as a sensor, and display the surround view environment information of the passing side of the vehicle through the electronic outside rearview mirror to complete the driver's field of view, that is, collect the environmental information through the surround view camera on the passing side of the vehicle, process the environmental information collected by the surround view camera, and send the processing result to the electronic outside rearview mirror through the data transmission unit through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror controller in turn, thereby improving the driving safety of the vehicle.

[0113] In summary, in the case that the meeting space is less than or equal to the preset space, and there is no collision object that can collide with the vehicle on the non-meeting side, the embodiment of the application can reuse the side rearview camera on the non-meeting side to complete the driver's field of view, and reuse the surround view camera on the meeting side to cope with the flexible and variable environment on the meeting side.

[0114] Optionally, in some embodiments, after the environmental information is received by the data transmission unit, the environmental information is processed, and the processing result is sent to the data transmission unit to send the processing result to the electronic outside rearview mirror through the data transmission unit, including: after the environmental information collected by the left and right surround view cameras of the vehicle is received by the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic outside rearview mirror through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror in turn through the data transmission unit; the left and right surround view cameras are one of the sensors included in the intelligent driving system.

[0115] Here, when there is a collision object that can collide with the vehicle on the non-meeting side, the signal transmission link selected by the embodiment of the application is described.

[0116] When there is a collision object that can collide with the vehicle on the non-meeting side, the environment on both sides of the vehicle is relatively complex, especially when the collision object is a moving target obstacle, the variable and complex road environment can seriously affect the driving safety of the vehicle.

[0117] At this time, the embodiment of the application can collect the surround view environmental information on both sides of the vehicle by reusing the left and right surround view cameras of the intelligent driving system, and display it through the electronic outside rearview mirror, thereby completing the driver's all-around field of view, so that the driver can reasonably avoid obstacles while coping with the meeting vehicle according to the display content of the electronic outside rearview mirror.

[0118] That is to say, when the sensor selected by the embodiment of the application is the left and right surround view cameras, the embodiment of the application can process the environmental information collected by the left and right surround view cameras, and send the processing result to the electronic outside rearview mirror through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror controller in turn through the data transmission unit, thereby improving the driving safety of the vehicle.

[0119] In the case that the meeting space is less than or equal to the preset space, and there is a collision object that can collide with the vehicle on the non-meeting side, the embodiment of the application can reuse the left and right surround view cameras as sensors, and select the corresponding transmission link based on the signal source, display the collected environmental information through the electronic outside rearview mirror, improve the data transmission efficiency, reduce the vehicle cost, simplify the vehicle architecture, and at the same time, have a wider application range, and provide the driver with a complete left and right surround view of the vehicle, so as to facilitate the driver to drive the vehicle to avoid the collision object.

[0120] Optionally, in some embodiments, the second transmission path of the environmental information corresponding to the actual vehicle speed is controlled according to the actual vehicle speed, comprising: in the case that the actual vehicle speed is greater than the preset vehicle speed, a second 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 outside rearview mirror; in the case that the actual vehicle speed is less than or equal to the preset vehicle speed, it is judged whether there is a collision object that can collide with the vehicle on the non-meeting side of the vehicle; if there is no collision object that can collide with the vehicle, a second 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 outside rearview mirror, or 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 to send the processing result to the electronic outside rearview mirror through the data transmission unit; if there is a collision object that can collide with the vehicle, 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 to send the processing result to the electronic outside rearview mirror through the data transmission unit.

[0121] Here, the second transmission path is described in detail.

[0122] The embodiment of the application can consider that the current driving road of the vehicle is not an environment complex urban traffic road when the actual vehicle speed is greater than the preset vehicle speed, at this time, the current driving road of the vehicle can be a city expressway, viaduct or highway, etc., and the probability of obstacles such as pedestrians, bicycles, motorcycles, tricycles, railings, water horses, cone barrels and walls is extremely low. When the driver drives the vehicle at high speed, the driver's attention is focused on the front, and it is difficult to divide the attention to observe the display content of the rearview mirror which is too detailed, therefore, it is not necessary to obtain too detailed spatial environmental information, the embodiment of the application can reuse the left and right side rearview cameras in the intelligent driving system as sensors to obtain the environmental information of the left side, the right side and the rear of the vehicle, and display the content through the electronic outside rearview mirror, thereby completing the driver's field of view. At this time, the transmission link can be that the environmental information is collected by using the left and right side rearview cameras of the vehicle, and the environmental information is transmitted through the data transmission unit and the electronic outside rearview mirror controller to the electronic outside rearview mirror in turn by using the data transmission unit.

[0123] The embodiment of the present application can determine whether there is a collision object that may collide with the vehicle on the non-meeting side of the vehicle when the actual vehicle speed is less than or equal to the preset vehicle speed, so as to use the corresponding sensor and signal transmission link based on the environmental state of the non-meeting side. The preset vehicle speed can be set by a person skilled in the art, for example, the preset vehicle speed can be 30 kph, which is not limited here.

[0124] When there is no collision object that may collide with the vehicle on the non-meeting side, the signal transmission link can be divided into two types:

[0125] The environmental information collected by the sensor is sent to the data transmission unit, and the data transmission unit directly sends the environmental information to the electronic outside rearview mirror, that is, the bypass link of the transmission path 1 is used.

[0126] The environmental information collected by the sensor is sent to the data transmission unit, and the data transmission unit sends the processing result of the environmental information to the electronic outside rearview mirror controller after receiving the environmental information, and processes the environmental information after the electronic outside rearview mirror controller receives the environmental information, and sends the processing result to the data transmission unit, so as to send the processing result to the electronic outside rearview mirror through the data transmission unit, that is, the SOC link of the transmission path 2 is used.

[0127] When there is an obstacle that may collide with the vehicle on the non-meeting side, the signal transmission link can be: the environmental information collected by the sensor is sent to the data transmission unit, and the data transmission unit sends the processing result of the environmental information to the electronic outside rearview mirror controller after receiving the environmental information, and processes the environmental information after the electronic outside rearview mirror controller receives the environmental information, and sends the processing result to the data transmission unit, so as to send the processing result to the electronic outside rearview mirror through the data transmission unit, that is, the SOC link of the transmission path 2 is used.

[0128] It should be noted that the selection of the transmission link of the embodiment of the present application will be described in detail below.

[0129] Through the above technical solution, different sensors can be selected to obtain environmental information based on the situation of the non-meeting side of the vehicle when the actual vehicle speed is less than or equal to the preset vehicle speed, and different data transmission links are selected based on different sensors and environmental information, which improves the data transmission efficiency, improves the practicality of the device of the vehicle, reduces the cost of the vehicle, simplifies the architecture of the vehicle, and has a wider application range.

[0130] Optionally, in some embodiments, the second 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 outside rearview mirror, or 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 to send the processing result to the electronic outside rearview mirror through the data transmission unit, comprising: sending the second control signal to the data transmission unit to control the data transmission unit to send the environmental information collected by the side rearview camera on the non-passing side of the vehicle to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn; the side rearview camera is one of the sensors included in the intelligent driving system; after receiving the environmental information collected by the surround view camera on the passing side of the vehicle through the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic outside rearview mirror through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror in turn; the surround view camera is one of the sensors included in the intelligent driving system.

[0131] Here, when there is no collision object on the non-passing side that may collide with the vehicle, the signal transmission link selected by the embodiment of the application is described.

[0132] When there is no obstacle on the non-passing side that may collide with the vehicle, only the side rear view needs to be provided on the non-passing side to complete the driver's blind area, at this time, the embodiment of the application can reuse the side rearview camera as a sensor, and display the side rear environment information on the non-passing side of the vehicle through the electronic outside rearview mirror, that is, collect the environmental information through the side rearview camera on the non-passing side of the vehicle, and transmit the environmental information through the data transmission unit to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn.

[0133] For the passing side, due to the complexity and variability of the environment, at this time, the embodiment of the application can reuse the surround view camera as a sensor, and display the surround view environment information on the passing side of the vehicle through the electronic outside rearview mirror to complete the driver's field of view, that is, collect the environmental information through the surround view camera on the passing side of the vehicle, process the environmental information collected by the surround view camera, and send the processing result to the electronic outside rearview mirror through the data transmission unit, the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror controller in turn, thereby improving the driving safety of the vehicle.

[0134] In the case that the actual vehicle speed is less than or equal to the preset vehicle speed and there is no collision object on the non-meeting side that can collide with the vehicle, the embodiment of the application can reuse the side rear camera on the non-meeting side to complete the driver's field of view, and reuse the surround view camera on the meeting side to cope with the flexible and changeable environment on the meeting side. According to different signal sources, the corresponding transmission link is selected, so that different data transmission methods are used according to different actual environments and different sensors, the data transmission efficiency is improved, the vehicle cost is reduced, the vehicle architecture is simplified, and the application range is wider.

[0135] Optionally, in some embodiments, after the environmental information is received by the data transmission unit, the environmental information is processed, and the processing result is sent to the data transmission unit to send the processing result to the electronic outside rearview mirror through the data transmission unit, including: after the environmental information collected by the left and right surround view cameras of the vehicle is received by the data transmission unit, the environmental information is processed, and the processing result is sent to the electronic outside rearview mirror through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror in sequence through the data transmission unit; the left and right surround view cameras are one of the sensors included in the intelligent driving system.

[0136] Here, the signal transmission link selected by the embodiment of the application when there is a collision object on the non-meeting side that can collide with the vehicle is described.

[0137] When there is a collision object on the non-meeting side that can collide with the vehicle, the environment on both sides of the vehicle is relatively complex, especially when the collision object is a moving target obstacle, the variable and complex road environment can seriously affect the driving safety of the vehicle.

[0138] At this time, the embodiment of the application can reuse the left and right surround view cameras of the intelligent driving system to collect the surround view environmental information on both sides of the vehicle and display it through the electronic outside rearview mirror, thereby completing the driver's all-around field of view, so that the driver can reasonably avoid obstacles while coping with the meeting vehicle according to the display content of the electronic outside rearview mirror.

[0139] That is, when the sensor selected by the embodiment of the application is the left and right surround view cameras, the embodiment of the application can process the environmental information collected by the left and right surround view cameras, and send the processing result to the electronic outside rearview mirror through the intelligent driving controller, the data transmission unit and the electronic outside rearview mirror controller in sequence through the data transmission unit, thereby improving the driving safety of the vehicle.

[0140] When the space for oncoming traffic is less than or equal to a preset space, and there is a collision object on the non-oncoming side that may collide with the vehicle, the embodiments of this application can reuse the left and right surround view cameras as sensors, and select the appropriate transmission link based on the signal source to display the collected environmental information through the electronic rearview mirror, thereby improving data transmission efficiency, reducing vehicle costs, simplifying vehicle architecture, and having a wider range of applications. At the same time, it provides the driver with a complete left and right surround view of the vehicle, making it easier for the driver to avoid collision objects.

[0141] In summary, the embodiments of this application can select the appropriate transmission link based on the passing space and the actual vehicle speed. The sensor strategy and controller control selected based on the passing space and the actual vehicle speed can be shown in Table 1, which is a strategy selection table.

[0142] Table 1

[0143]

[0144] In actual operation, as shown in Table 1, when the intelligent driving controller detects that the vehicle is in a meeting scenario (i.e., the distance between the vehicle and an oncoming vehicle in the adjacent lane is less than 1 meter), if the meeting space is large or the vehicle speed is greater than 30 kph, the controller uses the rear-view data from the left and right sides of the side-view cameras to control the serializer to output the bypass link rear-view data from the left and right sides of the side-view cameras. If the meeting space is small or the vehicle speed is less than or equal to 30 kph, the controller further determines whether there are any obstacles on the non-meeting side that could cause a collision. If there are no collision structures, the controller uses the surround-view data from the surround-view cameras on the meeting side to control one output of the serializer to the SOC link surround-view data, and uses the rear-view data from the left and right sides of the side-view cameras on the non-meeting side to control one output of the serializer to the bypass link rear-view data from the left and right sides of the side-view cameras. If there are collision structures, the controller uses the surround-view data from the left and right sides of the surround-view cameras to control the serializer to output the SOC link left and right surround-view data.

[0145] To complement the above embodiments, such as Figure 8 The diagram shows the information interaction of the intelligent driving system. The system obtains road environment information through intelligent driving sensors and transmits the corresponding information to the intelligent driving controller 8 to determine the oncoming traffic scenario. Then, based on the oncoming traffic space, oncoming traffic speed and / or whether there is a collision object on the non-oncoming side, the system acquires the corresponding camera data to control the electronic rearview mirror to display the corresponding image.

[0146] This allows the embodiments of this application to retrieve camera video information based on the judgment results of different oncoming vehicle scenarios, and control the electronic external camera display screen to display the video. This achieves comprehensive utilization of vehicle resources and makes vehicle driving more convenient and intelligent.

[0147] In summary, this application can obtain the required oncoming traffic environment information for the electronic rearview mirror from the environmental data collected by the vehicle's existing sensors based on the oncoming traffic space and speed, and determine the corresponding transmission path. This provides data support for the electronic rearview mirror display, improves data transmission efficiency, further simplifies the architecture of the electronic rearview mirror, enhances the practicality of vehicle components, reduces vehicle costs, simplifies vehicle architecture, and simultaneously supplements the driver's field of vision, assists the driver in driving, and improves vehicle driving safety.
