[0061] The technical solutions in the present application will be described clearly and exhaustively below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist together, and B exists alone, in addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0062] Hereinafter, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features.

[0063] Traditional rearview mirrors reflect the road surface and surrounding scenery through a mirror, and can only see limited and single direction information, which produces a blind area and easily causes traffic accidents. In order to improve this situation, the design of rearview mirrors gradually uses cameras to replace mirrors to capture the situation around the vehicle, and displays on the display screen in the cab, as shown in Figure 1 The driver can directly see the camera image and perceive the environment in real time.

[0064] For the existing electronic outside rearview mirror (Camera Monitor System, CMS), first, as shown in Figures 2-3 Two cameras are linked through a coaxial line in an electronic outside rearview mirror controller, and one electronic outside rearview mirror controller drives the display screens of the left and right electronic outside rearview mirrors to display images, Figure 2 Two cameras are linked through a coaxial line in two electronic outside rearview mirror controllers, and two electronic outside rearview mirror controllers drive the display screens of the left and right electronic outside rearview mirrors to display images. Figure 3 Secondly, since the electronic outside rearview mirror only has a single side view angle, there are many blind areas that cannot be identified, in order to solve this problem, as shown in

[0065] The rearview mirror is usually equipped with no less than 8 visible light cameras, which simultaneously collect environmental information in the front, rear, left and right directions of the vehicle. Figure 4 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 and poor multiplexing of vehicle devices, difficulty in realizing maximum 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.

[0066] Next, the application scenarios or system architecture of the embodiments of the present application will be described. Referring to

[0067] Figure 5 ​The vehicle comprises an intelligent driving system 10 and an electronic outside rearview system 20, the intelligent driving system 10 comprises a sensor 11, a data transmission unit 12 and an intelligent driving controller 13, and the electronic outside rearview system 20 is distinguished from the electronic outside rearview mirror in the prior art, only having an electronic outside rearview mirror controller 21 and an electronic outside rearview mirror 22, wherein the sensor 11 is used to collect environmental information, 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 outside rearview mirror controller 21, the intelligent driving controller 13 can 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 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, so that the electronic outside rearview mirror controller 21 processes the information, and the electronic outside rearview mirror 22 performs corresponding display.

[0068] As a possible implementation mode, as shown in Figure 6 The sensor 11 can include but is not limited to a side-view camera 111 and an all-around-view camera 112, and the side-view camera 111 can include but is not limited to a side front-view camera and a side rear-view camera, thereby collecting corresponding side front-view camera information and side rear-view camera information as environmental information.

[0069] In addition, as a possible implementation mode, as shown in Figure 6 In addition to the corresponding sensor 11, the camera also comprises a corresponding serializer for serial processing of information, and the data transmission unit 12 comprises a corresponding deserializer and serializer (as shown in the deserializer 121, the deserializer 123 and the serializer 122), for deserializing the information collected by the sensor 11, and 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 outside rearview system 20 for deserialization, and finally the electronic outside rearview mirror controller 21 controls the electronic outside rearview mirror 22 to display the deserialized information.

[0070] The transmission path can be but not limited to two paths:

[0071] Transmission path 1: After the environmental information is collected by the side-view camera 111 of the sensor 11 and 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 control signal of the intelligent driving controller 13, the serializer 122 sends it to the electronic outside rearview mirror 22, that is, uses the bypass link, so as not to pass through the intelligent driving controller 13, thereby improving the 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, the method includes the following steps:

[0076] In step S701, when it is detected that the vehicle is in a high-speed driving condition, the vehicle's driving phase at high speed is detected.

[0077] It is understandable that a vehicle's high-speed driving condition can include the driving conditions when entering a highway, the driving conditions when exiting a highway, and the driving conditions when traveling on a highway. Furthermore, the determination of a vehicle's driving phase on a highway can be made, but is not limited to, through environmental information.

[0078] In step S702, the transmission path of the environment information corresponding to the driving stage is controlled according to the driving stage, so that the environment information is transmitted to the electronic outside rearview mirror according to the transmission path for display; wherein the environment information is collected by a sensor.

[0079] It can be understood that the embodiments of the present application can control the transmission path of the environment information corresponding to the driving stage according to the driving stage, and display the environment information in real time on the electronic outside rearview mirror display screen, helping the user to obtain the corresponding vehicle external environment picture when the vehicle is driving at high speed, and realizing intelligent interaction between the electronic outside rearview mirror and the environment. The environment information in the embodiments of the present application is collected by a sensor, such as the environment information of the target object collected by the surround view camera or the side view camera, that is, the surround view camera or the side view camera is one of the sensors, but is not limited to the surround view camera and the side view camera.

[0080] In actual execution process, at least one electronic outside rearview mirror of the vehicle has at least one electronic outside rearview mirror display screen, the electronic outside rearview mirror display screen can realize the picture display function of the electronic outside rearview mirror, and the picture content is the driving stage information collected by the visual sensor in the high-speed driving condition of the vehicle, which can help the user to realize intelligent visual perception around the vehicle when the vehicle is driving at high speed.

[0081] Optionally, in some embodiments, the transmission path of the environment information corresponding to the driving stage is controlled according to the driving stage, including: based on the driving stage, sending a control signal to the data transmission unit to control the data transmission unit to send the environment information sent by the sensor to the electronic outside rearview mirror;

[0082] It can be understood that the embodiments of the present application can send a control signal to the data transmission unit based on the position of each target object, so as to display the environment information in real time on the electronic outside rearview mirror, help the user to obtain the corresponding vehicle external environment picture when the vehicle is driving at high speed, further help the user to obtain the corresponding vehicle external environment picture when the vehicle is driving at high speed, and improve the intelligence of the vehicle.

[0083] In actual execution process, at least one electronic outside rearview mirror of the vehicle has at least one electronic outside rearview mirror display screen, the electronic outside rearview mirror display screen can realize the picture display function of the electronic outside rearview mirror, and the picture content is the driving stage information collected by the visual sensor in the high-speed driving condition of the vehicle, which can help the user to realize intelligent visual perception around the vehicle when the vehicle is driving at high speed.

[0084] Optionally, in some embodiments, based on the driving stage, the control signal is sent to the data transmission unit to control the data transmission unit to send the sensor transmitted environmental information to the electronic outside rearview mirror, comprising: when the driving stage is the ramp merging into the main road stage, 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 corresponding to the driving stage to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0085] It can be understood that in the embodiments of the present application, the main road ramp-out scene can be, but is not limited to, the scene of the vehicle driving on the main road of the highway and driving from the main road to the ramp, and when the vehicle is in the rightmost lane of the highway relative to the driver, the right side front view data and the left side rear view data of the side view camera data are extracted from the environmental data, and the sensors include but are not limited to vehicle cameras, millimeter waves, ultrasonic waves or laser radars, etc., which are all intelligent driving accessories.

[0086] In actual execution process, as shown in Table 1, when the driving stage is the ramp merging into the main road stage, the transmission path 1, i.e. the bypass link, can be used in the embodiments of the present application, specifically: the intelligent driving controller sends a control signal (to control the link connection) to the data transmission unit to control the data transmission unit to send the environmental information collected by the side front view camera on one side of the driving direction of the highway corresponding to the position to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn, without the need for the intelligent driving controller to process, wherein the side front view camera is one of the sensors included in the intelligent driving system, providing data support for the electronic outside rearview mirror display, realizing intelligent interaction between the electronic outside rearview mirror and the environment.

[0087] Table 1

[0088]

[0089] Specifically, when the intelligent driving controller detects that the vehicle is in the driving condition of the highway, such as when the driving stage is the ramp merging into the main road stage, the left and right side rearview cameras are used as data sources, the bypass link of the transmission path 1 is used, and the data is sent to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn, for example, as shown in Figure 6 After the environmental information is collected by the sensor and processed in series, it is transmitted to the deserializer of the data transmission unit through the signal transmission line, the deserializer of the data transmission unit sends the deserialized data to the serializer of the data transmission unit, and after receiving the transmission instruction of the intelligent driving controller, the serializer sends the data to the electronic outside rearview mirror, that is, the bypass link is used for transmission, so that the data does not pass through the intelligent driving controller, improving the timeliness of the information and improving the display efficiency.

[0090] In view of the fact that the data transmission unit of the intelligent driving system has a serializer, and the serializer has only one bypass interface, the bypass link has only one, and considering that the main replacement of the electronic outside rearview mirror is the physical outside rearview mirror, the field of view mainly targets the rear distance of the vehicle, and the side view is most similar, without changing the architecture, the timeliness of the data is ensured, and the embodiment of the application can select to transmit the related environmental information of the side view of the more application scenarios through the bypass link, thereby providing data support for the display of the electronic outside rearview mirror, realizing intelligent interaction between the electronic outside rearview mirror and the environment, reducing the cost of the vehicle, and simplifying the architecture of the vehicle.

[0091] In addition, in order to cooperate with the above embodiment, as shown in Figure 8 the information interaction schematic diagram of the intelligent driving system, the current position information of the vehicle can be obtained through intelligent driving high-precision positioning, high-precision map information can be obtained through intelligent driving high-precision map, environmental information can be obtained through sensors, and the corresponding information is transmitted to the intelligent driving controller to realize the detection of the high-speed driving condition. The environmental information around the vehicle can be detected in real time to avoid obstacles and other vehicle control behaviors. The environmental information can be obtained through sensors, and the corresponding information is transmitted to the intelligent driving controller to determine the high-speed driving direction side rearview data of the side view camera data, to control at least one electronic outside rearview mirror to display the left and right side rearview data, and to clearly and refine the source of the displayed environmental information. While effectively utilizing the resources of the whole vehicle, the cost of the vehicle is reduced, and the architecture of the vehicle is simplified.

[0092] Optionally, in some embodiments, as shown in Table 1, based on the driving stage, 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 outside rearview mirror, including: when the driving stage is the main road driving stage, 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 corresponding to the driving stage to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in sequence. The left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0093] Specifically, as shown in Table 1, when the position is the main road driving stage, the left and right side rearview cameras can be used as data sources, and the driving controller sends a control signal to the data transmission unit to control the data transmission unit to send the environmental information collected by the left and right side rearview cameras to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in sequence, for example, as shown in Figure 6As shown in the figure, after the environmental information is collected by the sensor and processed in series, it is transmitted to the deserializer of the data transmission unit through the signal transmission line. The deserializer of the data transmission unit sends the deserialized data to the serializer of the data transmission unit. After receiving the transmission instruction of the intelligent driving controller, the serializer sends the data to the electronic outside rearview mirror, i.e., the bypass link, so that the data does not pass through the intelligent driving controller, thereby improving the display efficiency.

[0094] It should be noted that, since there is only one bypass link, the output is the interface of the serializer of the intelligent data transmission unit. Therefore, in the embodiment of the present application, the related environmental information of the side view is transmitted through the bypass link, so that the timeliness is faster and more suitable for actual application, thereby improving the reliability and practicality of the method. However, the specific implementation mode can be various, and can be set by the person skilled in the art according to the actual situation, which is not limited specifically herein.

[0095] Optionally, in some embodiments, as shown in Table 1, based on the driving stage, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the sensor to the electronic outside rearview mirror, including: when the driving stage is the main road exit ramp stage, judging whether the vehicle is in the rightmost lane on the highway; if it is in the rightmost lane on the highway, a control signal is sent to the data transmission unit to control the data transmission unit to send the environmental information collected by the side front camera on the right side of the vehicle and the side rear view camera on the left side of the vehicle to the electronic outside rearview mirror in turn through the data transmission unit and the electronic outside rearview mirror controller; the side front camera and the side rear view camera are both sensors included in the intelligent driving system.

[0096] Specifically, as shown in Table 1, when the driving stage is the main road exit ramp stage, the present application can judge whether the vehicle is in the rightmost lane on the highway. If it is in the rightmost lane on the highway, the side front camera on the right side of the vehicle and the side rear view camera on the left side of the vehicle can be used as data sources. The driving controller sends a control signal to the data transmission unit to control the data transmission unit to send the environmental information collected by the side front camera on the right side of the vehicle and the side rear view camera on the left side of the vehicle to the electronic outside rearview mirror in turn through the data transmission unit and the electronic outside rearview mirror controller, for example, as shown in the figure. Figure 6 As shown in the figure, after the environmental information is collected by the sensor and processed in series, it is transmitted to the deserializer of the data transmission unit through the signal transmission line. The deserializer of the data transmission unit sends the deserialized data to the serializer of the data transmission unit. After receiving the transmission instruction of the intelligent driving controller, the serializer sends the data to the electronic outside rearview mirror, i.e., the bypass link, so that the data does not pass through the intelligent driving controller, thereby improving the display efficiency.

[0097] It should be noted that, since there is only one bypass link, the output is the interface of a serializer of the intelligent data transmission unit, therefore, the embodiment of the present application will transmit the related environment information of the side view through the bypass link, so that the timeliness is faster, and it is more suitable for practical application, and the reliability and practicality of the method are improved, but the specific implementation mode is various, and can be set by the person skilled in the art according to the actual situation, and is not limited specifically here.

[0098] Optionally, in some embodiments, as shown in Table 1, based on the driving stage, the control signal is sent to the data transmission unit to control the data transmission unit to send the environment information sent by the sensor to the electronic outside rearview mirror, and further comprising: if not in the rightmost lane on the highway, the control signal is sent to the data transmission unit to control the data transmission unit to send the environment information collected by the left and right side rearview cameras of the vehicle to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn; the left and right side rearview cameras are one of the sensors included in the intelligent driving system.

[0099] Specifically, as shown in Table 1, when the driving stage is the main road off-ramp stage and the vehicle is not in the rightmost lane on the highway, the embodiment of the present application can use the left and right side rearview cameras as the data source, and the driving controller sends a control signal to the data transmission unit to control the data transmission unit to send the environment information collected by the left and right side rearview cameras to the electronic outside rearview mirror through the data transmission unit and the electronic outside rearview mirror controller in turn, for example, as shown in Figure 6 After the environment information is collected by the sensor and processed in series, it is transmitted to the deserializer of the data transmission unit through the signal transmission line, the deserializer of the data transmission unit sends the deserialized data to the serializer of the data transmission unit, and after receiving the transmission instruction of the intelligent driving controller, the serializer sends the data to the electronic outside rearview mirror, that is, the bypass link, so that the data does not pass through the intelligent driving controller, and the display efficiency is improved.

[0100] It should be noted that, since there is only one bypass link, the output is the interface of a serializer of the intelligent data transmission unit, therefore, the embodiment of the present application will transmit the related environment information of the side view through the bypass link, so that the timeliness is faster, and it is more suitable for practical application, and the reliability and practicality of the method are improved, but the specific implementation mode is various, and can be set by the person skilled in the art according to the actual situation, and is not limited specifically here.

[0101] Optionally, in some embodiments, determining whether the vehicle is in the rightmost lane on the highway comprises: obtaining the current position of the vehicle; and determining whether the vehicle is in the rightmost lane according to the current position and preset map information.

[0103] It should be noted that the preset map information can be set by those skilled in the art according to actual conditions, which is not specifically limited here.

[0104] Specifically, as shown in Figure 9 , the position information of the whole vehicle can be obtained by using related technologies such as GNSS (Global Navigation Satellite System), and the position of the vehicle can be determined by the positioning algorithm after being collected by the vehicle TBOX to obtain the final positioning result. The intelligent driving high-precision map function in the embodiments of the present application can provide the vehicle map information required by the intelligent driving system to assist the user in end-to-end intelligent driving control, and the road information in front of the path can be obtained in advance, as shown in Figure 10 , wherein the left side of the figure is a smooth intersection virtual lane, and the high-precision map elements include road elements, intersection elements, traffic signal elements, logical relationship elements and other road object elements; the intelligent driving controller in the embodiments of the present application can receive high-precision map, high-precision positioning, sensor and other information to perform reasonable control of the vehicle and realize the function of the intelligent driving domain.

[0105] For example, during driving, the actual position a of the vehicle can be confirmed based on the high-precision positioning function, the data element set of the position a in the high-precision map is obtained, and then the actual position of the vehicle can be matched according to the data element set of the high-precision map, wherein the road elements can provide lane width and road sign information, the intersection elements include roundabouts, fork intersections and traffic signal information, and the logical relationship elements can describe the topological relationship of the intersection and the road. Based on the obtained high-precision map data elements, information interaction is performed to finally determine the position of the vehicle.

[0106] In summary, this application can send environmental information corresponding to the location of a target object to the electronic rearview mirror via a corresponding transmission path when the vehicle is traveling at high speed, or directly to the electronic rearview mirror when no target object exists. This provides data support for the electronic rearview mirror display, enabling intelligent interaction between the electronic rearview mirror and the environment, improving vehicle usability, reducing vehicle costs, and simplifying vehicle architecture.
