Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a method and device for adjusting the field of view of a vehicle, an electronic device and a readable storage medium. BACKGROUND

[0002] The field of view of a vehicle is mostly dependent on physical rearview mirrors, but the field of view of a vehicle rearview mirror is fixed, and is usually used to provide the driver with a fixed angle of rear and side view. However, for large vehicles such as commercial trucks and semi-trailers, the angle between the trailer and the main vehicle often changes when the driver turns or changes lanes, which can lead to insufficient coverage of the field of view of the physical rearview mirror, especially in complex road conditions and adverse weather conditions. This blind spot problem can cause serious road safety accidents.

[0003] With the development of intelligent driving technology, electronic rearview mirrors (Camera Monitoring System, CMS for short) as a new type of indirect field of view device have begun to be applied on vehicles. Electronic rearview mirrors use cameras to capture the environment around the vehicle in real time and transmit it to the display in the cab, providing a clearer and wider angle of view of the environment, especially at night and in adverse weather conditions, which far exceeds the performance of traditional physical rearview mirrors. However, the existing electronic rearview mirror field of view control method mainly relies on a pre-set field of view, which often cannot adapt to the complex changes in the field of view requirements when the vehicle is dynamically turning or changing lanes.

[0004] In view of the technical problem that the fixed field of view of the vehicle rearview mirror cannot meet the driving requirements of the vehicle, no effective solution has been proposed so far. SUMMARY

[0026] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort should belong to the scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", and the like in the description and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, functional component or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, functional component or device.

[0028] According to the embodiments of the present application, an embodiment of a field of view adjustment method of a vehicle is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0029] Figure 1 is a flowchart of a field of view adjustment method of a vehicle according to the embodiments of the present application, as Figure 1 shown, the method can include the following steps:

[0030] Step S101, in response to an activation signal of a field of view following function of a rearview mirror in a vehicle, performing an activation operation on the field of view following function.

[0031] In the technical solution provided by the above step S101 of the present application, the field of view following function is used to adjust the field of view display range of the rearview mirror in the display of the vehicle, and the rearview mirror can be an electronic rearview mirror, which can be composed of a camera assembly, a display assembly and a control unit, wherein the camera assembly is used to obtain information on the left and right sides of the vehicle and the front lower part of the vehicle, convert the external image of the vehicle into a video signal, and display the processed video signal on the display. The above vehicle can be a towing trailer.

[0032] In this embodiment, the activation signal of the field of view following function of the rearview mirror can be activated by the driver of the vehicle through a field of view following physical switch in the vehicle or a field of view following control in the display interface of the central control screen of the vehicle. The physical switch is usually a physical button or knob, and the physical switch is usually arranged at a position convenient for the driver to operate, for example, the door area, which is only exemplary and does not limit the arrangement position of the physical switch. The field of view following control in the display interface is a software level interactive element, which can be controlled by touch operation to facilitate the driver to control accurately within the range of visual reach.

[0033] For example, when the field of view following function is in the off state, if it is detected that the driver presses the field of view following physical switch or detects that the driver performs touch operation on the field of view following control in the display interface, the operation signal will be transmitted to the camera monitoring system (CMS) controller of the field of view following function of the rearview mirror of the vehicle through the communication network (such as CAN bus) in the vehicle. After the CMS controller receives the operation signal, it can be considered that the activation signal of the field of view following function of the rearview mirror is responded, and in this case, the activation operation of the field of view following function can be performed.

[0034] Optionally, the activation operation of the field of view following function can be initiated by the CMS controller to change the system instruction and state to change the field of view following function from the off state to the working state.

[0035] In this step, in response to the activation signal of the field of view following function, the field of view following function of the rearview mirror of the vehicle can be activated, so as to dynamically adjust the field of view range of the rearview mirror of the vehicle when the vehicle performs turning and other operations, and make up for the field of view blind area of the traditional rearview mirror under complex driving conditions, so as to provide the driver with a more complete road observation angle, and thus improve the driving safety of the vehicle.

[0036] In step S102, in response to the field of view following function being successfully activated, the steering information of the vehicle is acquired.

[0037] In the technical solution provided in the above step S102 of the present application, after the field of view following function is successfully activated, the steering information of the vehicle can be acquired, and the steering information is used to represent the steering state of the vehicle, such as the vehicle is currently turning left or the vehicle is currently turning right.

[0038] In this embodiment, after the field of view following function is activated through the field of view following physical switch (such as knob, button, etc.) in the vehicle or the field of view following control in the display interface of the vehicle, the steering information of the vehicle can be acquired through the vehicle sensor.

[0039] Optionally, the sign of the successful activation of the field-of-view follow-up function of the rearview mirror is that a field-of-view follow-up icon is displayed in the vehicle display of the vehicle, which is not only a confirmation feedback to the operation of the driver on the field-of-view follow-up physical switch or the field-of-view follow-up control, but also indicates that the field-of-view follow-up function of the vehicle is ready to respond to the steering information.

[0040] Optionally, the steering information of the vehicle can be obtained through the steering system of the vehicle, wherein the steering system comprises a plurality of sensors, such as a steering wheel angle sensor, a vehicle body gyroscope, an accelerometer, etc., wherein the steering wheel sensor can capture the angle and speed of the steering wheel rotation of the vehicle; the vehicle body gyroscope can obtain the rotational angular velocity of the vehicle around each axis and the heading angle of the vehicle, for judging the turning degree of the vehicle. In addition, the steering lamp switch state and the vehicle speed signal can also provide steering assistance information for the system.

[0041] Optionally, the CMS controller can collect these sensor data in real time through the in-vehicle communication network (such as CAN bus), and analyze the steering features therein, such as steering direction, amplitude and speed, which together constitute a complete representation of the steering state.

[0042] Optionally, the acquisition of the steering information of the vehicle is dynamic and real-time, which ensures that the CMS controller can respond to the steering intention of the driver in time and provide the most timely field-of-view adjustment.

[0043] In this step, when the field-of-view follow-up function of the rearview mirror of the vehicle is in a successful activation state, the steering information of the vehicle is obtained, which is the core basis of the field-of-view follow-up function, for guiding the CMS controller to calculate and determine whether the field-of-view display range of the vehicle display needs to be adjusted and how to adjust the field-of-view display range of the display, and then to provide a complete field-of-view range when the vehicle turns or changes lanes, thereby greatly improving the driving safety and driving experience.

[0044] In step S103, the steering wheel angle signal of the vehicle is determined based on the steering information.

[0045] In the technical solution provided in the above step S103 of the present application, the steering wheel angle signal is used to represent the angle of the steering wheel rotation of the vehicle.

[0046] In this embodiment, after obtaining the steering information of the vehicle, the steering wheel angle signal can be extracted from the steering information of the vehicle, thereby providing a quantitative basis for field-of-view adjustment.

[0047] Optionally, as can be learned from the foregoing description, the steering information of the vehicle is mainly derived from the steering system of the vehicle, which can continuously monitor the steering state of the vehicle and transmit relevant information to the CMS controller through the vehicle-mounted network (e.g., CAN bus). The steering information not only represents the steering direction of the vehicle, but also reflects the degree of steering, i.e., the steering angle of the steering wheel. This information is the basis for dynamically adjusting the display field of the electronic rearview mirror.

[0048] Optionally, after obtaining the steering information of the vehicle, the CMS controller can analyze the received steering information and extract the steering wheel angle signal therefrom. This signal directly reflects the specific angle of the steering wheel when the driver performs the steering operation. For example, the CMS controller processes the steering information through an embedded algorithm to ensure that the steering wheel angle signal can timely and accurately reflect the change in the steering state of the vehicle.

[0049] In this step, determining the steering wheel angle signal of the vehicle according to the steering information of the vehicle is a key prerequisite for implementing the field follow-up function. The steering wheel angle signal is directly used to guide the dynamic adjustment of the field display range of the display vehicle rearview mirror to ensure that the field requirement of the vehicle when turning or changing lanes is met.

[0050] In step S104, in response to the steering wheel angle signal indicating that the steering angle of the steering wheel is greater than a preset angle threshold, the field display range of the display is adjusted from the original field range to the target field range.

[0051] In the technical solution provided in the foregoing step S104 of the present application, the above-mentioned steering wheel angle signal is used to reflect the degree of the steering operation being performed by the driver of the vehicle. This signal is crucial for judging whether the field of the electronic rearview mirror needs to be dynamically adjusted. The above-mentioned original field range is used to represent the field area of the rearview mirror in the straight driving mode of the vehicle, and the target field range is used to represent the field area of the rearview mirror in the turning mode of the vehicle, which changes with the change in the steering angle of the steering wheel.

[0052] In this embodiment, if the steering wheel angle signal indicates that the steering angle of the steering wheel is greater than the preset angle threshold, it can be considered that the driver of the vehicle is performing an effective turning operation, thereby triggering the adjustment of the field display range and adjusting the field range of the display from the original field range in the straight driving mode to the target field range in the turning mode. The above-mentioned preset angle threshold is a predefined value used to distinguish between slight steering (not enough to trigger field adjustment) and large amplitude steering (requiring field adjustment). The design of the preset angle threshold takes into account the normal operating state and driving habits of the vehicle, ensuring that the field adjustment is performed when it is really needed, and avoiding excessive intervention or invalid switching.

[0053] Optionally, the original field of view range is used to represent the default field of view area of the rearview mirror of the vehicle, which generally covers the visible area behind and on the side of the vehicle acquired by the rearview mirror of the vehicle. The target field of view range is used to represent the temporary field of view area of the rearview mirror in the turning mode of the vehicle, which can ensure that the vehicle has a wider field of view range when performing the turning operation, so as to ensure that the road conditions on the side and at the rear of the trailer of the vehicle are still clearly visible in the turning mode.

[0054] For example, when the vehicle performs the turning operation, the CMS controller calculates the size and direction of the field of view range to be adjusted according to the steering wheel turning angle signal through an internal algorithm. As the steering wheel turning angle increases, the field of view area displayed by the target field of view range is in a dynamic change process, so as to ensure that the driver can continuously observe the key field of view on the side and at the rear of the vehicle and reduce the visual blind area during the turning process.

[0055] Optionally, the adjustment of the field of view display range is a dynamic process. The CMS controller can continuously monitor the change of the steering wheel turning angle signal. Once the turning operation is completed and the steering wheel turning angle falls below the preset threshold, the field of view of the display will automatically return to the original field of view range, ensuring the normal field of view requirement in the straight driving state.

[0056] In this step, by monitoring and interpreting the steering wheel turning angle signal in real time, it can be intelligently judged when the field of view display range of the rearview mirror of the vehicle needs to be adjusted, so as to realize the smooth transition from the original field of view range to the target field of view range. This process ensures that the driver can obtain the necessary additional field of view when the vehicle turns or changes lanes, so as to avoid the blind area and improve the driving safety. At the same time, by setting the preset angle threshold, unnecessary adjustment of the viewing angle is avoided, and the stability of the driver's line of sight is maintained, which is of great significance to improve the driving safety and comfort of commercial trucks and large vehicles such as trailer tractors under complex road conditions and adverse weather conditions.

[0057] The above steps S101 to S104 of the present application, the rearview mirror of the vehicle has a field of view following function. After the field of view following function is activated, the field of view range of the rearview mirror of the vehicle can change according to the change of the turning angle of the steering wheel, so as to reduce the field of view blind area during the turning process, meet the driving requirement of the vehicle, and further improve the driving safety and comfort of the vehicle. The driver can have the best field of view range under various driving conditions, so as to solve the technical problem that the fixed field of view of the rearview mirror of the vehicle cannot meet the driving requirement of the vehicle.

[0058] The above method of the embodiment will be further introduced as follows.

[0059] As an optional embodiment, the step S102 of acquiring the steering information of the vehicle comprises: detecting a turn signal of the vehicle and a steering wheel rotation signal of the vehicle; and in response to the steering direction corresponding to the turn signal being the same as the steering direction corresponding to the steering wheel rotation signal, generating the steering information of the vehicle based on the turn signal and the steering wheel rotation signal.

[0060] In this embodiment, when acquiring the steering information of the vehicle, the turn signal of the vehicle and the steering wheel rotation signal of the vehicle can be detected. The turn signal of the vehicle is a direct reflection of the turning or lane changing intention of the vehicle. The turn signal switch of the vehicle is directly related to the turning intention, and the driver indicates the turning direction of the vehicle to be performed by actuating the turn signal switch. The steering wheel rotation signal reflects the actual turning operation of the driver. When the driver rotates the steering wheel, the angle sensor installed on the steering wheel shaft monitors this action and converts the specific rotation angle information into an electrical signal, which is transmitted to the CMS controller through the communication network (such as CAN bus) of the vehicle.

[0061] Optionally, after detecting the turn signal of the vehicle and the steering wheel rotation signal, the CMS controller can perform a matching and verification process of the turn signal and the steering wheel rotation signal. For example, it can be determined whether the steering direction indicated by the detected turn signal is consistent with the steering direction reflected by the steering wheel rotation signal. If the two are consistent, the CMS controller will generate a comprehensive steering information based on the two signals, which contains the specific direction (such as left turn or right turn) and the steering amplitude (i.e. the angle of the steering wheel rotation) of the vehicle turning.

[0062] Optionally, by comparing the turn signal and the steering wheel rotation signal, the accuracy of the vehicle steering information can be ensured. This avoids the influence of potential false operations (such as accidental touch of the turn signal switch or accidental movement of the steering wheel) on the visual field following function, thereby improving the safety of the entire control method.

[0063] Optionally, the combination of the turn signal and the steering wheel rotation signal enables the CMS controller to respond more quickly to the steering operation of the vehicle, ensuring the coordination between the visual field adjustment and the vehicle dynamics. This is particularly important in the scenario of making sharp turns or quickly changing lanes at high speed. Immediate and accurate visual field adjustment helps the driver quickly grasp the traffic situation around the vehicle, reducing the possibility of accidents.

[0064] In the above steps, the steering information of the vehicle is acquired through the turn signal of the vehicle and the steering wheel rotation signal of the vehicle. Not only the operation intention of the driver is concerned, but also the actual vehicle dynamics (steering wheel rotation signal) is considered, so that the real steering state of the vehicle can be more accurately reflected, the accuracy of the vehicle steering information is improved, and a solid foundation is laid for the intelligent control of subsequent visual field adjustment.

[0065] As an optional embodiment, the step S103 of determining the steering wheel angle signal of the vehicle based on the steering information comprises: analyzing the steering information to obtain an analysis result, wherein the analysis result is used to represent the steering direction and the steering amplitude of the vehicle; and determining the steering wheel angle signal of the vehicle based on the analysis result.

[0066] In this embodiment, as introduced above, the steering information is used to represent the steering state of the vehicle and can be obtained through the steering system of the vehicle. When determining the steering wheel angle of the vehicle based on the steering information, the steering information can be analyzed first to obtain an analysis result.

[0067] For example, the steering information can be first converted into a data format that can be understood by a preset analysis algorithm, and then the converted steering information is decoded and analyzed by the preset analysis algorithm to obtain the analysis result. The analysis result contains the steering direction (e.g., turning left or right), the steering amplitude (e.g., the angle of the steering wheel), and possibly the steering speed information of the vehicle.

[0068] Optionally, after obtaining the analysis result, the steering wheel angle of the vehicle can be calculated according to the steering direction and the steering amplitude in the analysis result, wherein the steering wheel angle is used to represent a specific numerical value of the actual steering angle of the steering wheel during the steering of the vehicle, and is a triggering condition for the adjustment of the field of view of the rearview mirror of the vehicle. For example, when the steering wheel angle of the vehicle is greater than a preset angle threshold, the adjustment of the field of view of the rearview mirror will be triggered.

[0069] As an optional embodiment, the field of view adjustment method of the vehicle further comprises: in response to the field of view follow-up function being in a successfully activated state, controlling the display of the vehicle to output opening information of the field of view follow-up function, wherein the opening information is used to remind the driver of the vehicle that the field of view follow-up function has been successfully activated.

[0070] In this embodiment, when the driver manually activates the field of view follow-up function through the field of view follow-up entity switch or the field of view follow-up control, the CMS controller will receive the activation signal. In order to confirm that this operation has been recognized and executed, the CMS controller can control the display of the vehicle to output the opening information of the field of view follow-up function to remind the driver that the field of view follow-up function of the rearview mirror of the vehicle has been successfully activated.

[0071] For example, the CMS controller can establish a connection with the vehicle display through the communication network inside the vehicle, such as the CAN bus. Once the field of view follow-up function is activated, the CMS controller can send a display instruction to the display, and the display can display information related to the field of view follow-up after receiving the display instruction. For example, the display can present an open icon, a text message or other forms of prompt information on the screen to inform the driver that the field of view follow-up function has been successfully activated and is adjusting the display field of view according to the steering state of the vehicle.

[0072] Optionally, after the field of view follow-up function is activated, controlling the vehicle display to output the opening information of the field of view follow-up function is an important visual feedback for the driver. On the one hand, it confirms that the driver's operation has taken effect, increasing the intuitiveness and trust of human-computer interaction; on the other hand, as a continuous visual prompt, it reminds the driver that during the subsequent driving process, the system will automatically adjust the field of view to meet the needs of turning or changing lanes.

[0073] By controlling the vehicle display to output the opening information of the field of view follow-up function when the field of view follow-up function is successfully activated, not only the automatic adjustment of the field of view follow-up function is realized, but also the user's sense of participation and control of the system are increased, ensuring that the driver can get timely feedback of the system state when needed, enhancing the driver's trust and dependence on the field of view adjustment, thereby improving the safety and comfort of the overall driving.

[0074] As an optional embodiment, the field of view adjustment method of the vehicle further includes: in response to a closing signal of the field of view follow-up function of the rearview mirror, closing the field of view follow-up function and controlling the field of view display range of the display to adjust from the target field of view range to the original field of view range.

[0075] In this embodiment, when the field of view follow-up function of the vehicle is successfully activated and in the working state, if a closing signal of the field of view follow-up function of the rearview mirror is received, the field of view follow-up function of the vehicle can be closed and the field of view display range of the vehicle display can be controlled to adjust from the target field of view range to the original field of view range, wherein the closing signal can be triggered by the driver's closing operation on the field of view follow-up physical switch or the field of view follow-up control.

[0076] For example, when the vehicle is performing straight driving, parking or other operations, or the driver judges that the current road conditions do not require additional field of view support, the field of view follow-up function of the vehicle can be manually closed.

[0077] Optionally, after receiving the closing signal of the field of view follow-up function, the CMS controller can perform the closing operation of the field of view follow-up function and stop responding to the steering wheel angle signal to avoid unnecessary field of view adjustment in the straight driving mode.

[0078] Optionally, after the field of view following function of the vehicle rearview mirror is closed, the closing icon of the field of view following function can also be displayed on the display to remind the driver that the field of view following function of the vehicle has been closed.

[0079] Optionally, when the field of view following function is closed, the CMS controller will control the display to smoothly transition the field of view display range from the target field of view range back to the original field of view range. This means that if the display was previously switched to a wider field of view angle because the vehicle was turning or changing lanes, after the function is closed, the field of view will return to the standard display range in straight-line mode. The transition process should be designed to be fast and smooth enough to avoid sudden visual impact on the driver, while also taking into account different driving speeds and scenarios to ensure smooth field of view switching in all cases.

[0080] Optionally, by allowing the driver to manually close the field of view following function and immediately return to the original field of view range, the driver's control ability over the vehicle's visual assistance system is enhanced, the subjective feelings and individual needs of the driver are considered, and the overall driving experience is improved.

[0081] Optionally, during the field of view adjustment of the rearview mirror, not only is intelligent field of view adjustment provided, but also the driver's manual intervention ability is retained, ensuring that the field of view following function of the rearview mirror can provide the most appropriate assistance in any driving situation, while minimizing potential interference or adverse effects.

[0082] As an optional implementation, after the display's field of view display range is adjusted from the original field of view range to the target field of view range, the vehicle's field of view adjustment method further includes: detecting the driving state of the vehicle, wherein the driving state is used to represent the driving mode executed by the vehicle; in response to the driving state indicating that the driving mode executed by the vehicle is a straight-line mode, controlling the display's field of view display range to adjust from the target field of view range to the original field of view range.

[0083] In this embodiment, after the field of view following function of the vehicle is successfully activated and the display's field of view display range is adjusted from the original field of view range to the target field of view range, the driving state of the vehicle can be monitored in real time, and the driving mode executed by the vehicle can be determined according to the driving state of the vehicle, wherein the driving mode can be at least a straight-line mode or a turning mode. If the driving mode currently executed by the vehicle is a straight-line mode, the display's field of view display range can be controlled to adjust from the target field of view range to the original field of view range to ensure that the field of view display range matches the driving state of the vehicle.

[0084] Optionally, the driving state information of the vehicle can be collected by a plurality of vehicle-mounted sensors and controllers, including but not limited to a vehicle speed sensor, a steering angle sensor, a gear position sensor, a vehicle body stability control system, etc. These sensors and systems can monitor the dynamic information of the vehicle in real time, and transmit the data to the CMS controller through a vehicle-mounted communication network (such as a CAN bus). Through comprehensive analysis of these information, the CMS controller can determine the current driving mode of the vehicle, i.e., whether it is in a straight driving mode.

[0085] Optionally, the straight driving mode is used to indicate that the vehicle maintains a straight driving state during driving without turning or lane changing. For the CMS controller, the main basis for determining that the vehicle is in a straight driving mode includes stable vehicle speed, steering wheel angle close to zero degrees, steering light not turned on, and the vehicle in a forward driving gear, etc. When the CMS controller detects the above driving state characteristics, it can be considered that the vehicle has entered a straight driving mode.

[0086] Optionally, after detecting that the vehicle is in a straight driving mode, the CMS controller will perform a recovery adjustment of the field of view display range. This adjustment process is usually accompanied by the vehicle returning to a straight driving state from a turning or lane changing state, ensuring that the field of view display range matches the driving state of the vehicle, avoiding unnecessary expansion or deviation of the field of view, and reducing the interference to the driver. Among them, the recovery of the field of view display range can be gradual, to smoothly transition to the original field of view range, avoiding sudden changes that cause visual discomfort to the driver.

[0087] In this step, by detecting the driving state of the vehicle and adjusting the field of view display range of the vehicle rearview mirror according to the driving mode, a comprehensive response to the driving state of the vehicle is achieved, ensuring the intelligence and dynamic adaptability of the field of view adjustment, and providing the driver with a safer and more intelligent driving assistance experience.

[0088] As an optional implementation, the activation signal of the field of view follow-up function is triggered by a field of view follow-up switch in the vehicle, or the activation signal of the field of view follow-up function is triggered by a field of view follow-up control in the display interface of the display of the vehicle.

[0089] In this embodiment, the driver is allowed to manually turn on the field of view follow-up function according to the actual driving needs, so as to obtain a wider field of view display when turning and lane changing.

[0090] Optionally, the field of view follow-up function of the vehicle can be turned on through a field of view follow-up switch in the vehicle, or through a field of view follow-up control in the display interface, wherein the field of view follow-up switch can also be referred to as a field of view follow-up physical switch, which is usually designed to be easily operated in the cab, such as on the control panel of the door area, to ensure that the driver can quickly and intuitively activate the field of view follow-up function in any driving state. This switch can be in the form of a knob, a button or a touch panel, and the design takes into account the driver's hand feeling and operation convenience.

[0091] Optionally, when the driver operates the field of view follow-up switch, the switch sends a signal to the vehicle controller (Data Communication Module, referred to as DCM) through the electrical circuit inside the vehicle, and the DCM transmits this signal to the CMS controller through the vehicle network (such as CAN bus). After the CMS controller receives the signal, it responds immediately, activates the field of view follow-up function, and displays the field of view follow-up on icon on the display to provide visual feedback and confirm the activation status of the function.

[0092] Optionally, the field of view follow-up function control can be an icon, a button or a slider on the interface of the vehicle display. The driver can operate this control through the touch screen or other input devices (such as a remote control) to turn on or off the field of view follow-up function.

[0093] Optionally, when the driver triggers the field of view follow-up function through the display interface, this operation signal is first received and processed by the vehicle terminal. The vehicle terminal transmits this activation signal to the CMS controller through the vehicle communication network. After the CMS controller receives the signal, it also activates the field of view follow-up function and displays the corresponding on icon on the display to ensure that the driver can immediately understand the status of the function.

[0094] Optionally, the priority of the field of view follow-up switch is higher than that of the field of view follow-up control, that is, if the driver manually operates the field of view follow-up switch, regardless of the state of the control in the display interface, the signal of the field of view follow-up switch will be processed first, and the field of view follow-up function will be activated or turned off immediately to ensure that the driver's intention can be quickly and accurately executed in an emergency or when the network communication is unstable.

[0095] Through the above two ways, the driver can choose the most suitable operation mode to activate the field of view follow-up function according to personal needs and driving scenarios, so as to obtain more comprehensive visual assistance when turning or changing lanes, and significantly improve driving safety and comfort. This semi-automatic control logic design takes into account user control and system intelligence.

[0096] As an optional implementation, the field of vision follow-up function of the vehicle is allowed to be activated when the vehicle is in the trailer state, and the field of vision follow-up function of the vehicle is not allowed to be activated when the vehicle is in the cargo state.

[0097] In this embodiment, the cargo state and the trailer state of the vehicle are based on two different configurations of the vehicle when performing a transportation task. The cargo state is used to indicate the case where the vehicle carries goods by itself without connecting any trailer. In this state, the size, weight distribution and overall handling of the vehicle are mainly affected by the structure of the vehicle itself and the loaded goods. The trailer state refers to the case where the vehicle connects one or more trailers (trucks) for goods transportation. The presence of the trailer significantly extends the length and width of the vehicle, changing the overall driving dynamics of the vehicle.

[0098] Optionally, when the vehicle is in the trailer state, the vehicle is connected to the trailer for operation, and its driving characteristics, field of vision range and perception ability to the surrounding environment have changed significantly. The presence of the trailer not only prolongs the total length of the vehicle, but also forms a different driving path from the main vehicle, especially when turning or changing lanes, the included angle between the trailer and the main vehicle can cause the traditional rearview mirror to fail to effectively cover the important visual information at the rear and side of the trailer. Therefore, in this case, the field of vision follow-up function of the vehicle is allowed to be manually activated by the driver, so that the field of vision area of the rearview mirror on the display can be adjusted in real time according to the dynamic changes of the vehicle (such as steering wheel angle, turn signal state, etc.), ensuring that the driver can continuously monitor the road condition information at the rear of the trailer and the side of the vehicle compartment, thereby significantly reducing the risk of collision or scratching and improving driving safety.

[0099] Optionally, when the vehicle is in the cargo state, that is, the vehicle transports goods independently without connecting the trailer, its visual needs and driving dynamics are relatively stable. In this case, the length, width and height of the vehicle change little, and the performance of the traditional rearview mirror or the CMS system in the default field of vision range is sufficient to meet the requirements of most driving environments. Therefore, in this case, the field of vision follow-up function of the vehicle is not allowed to be activated, so as to reduce unnecessary system load and avoid confusion or interference to the driver caused by excessive adjustment of the field of vision, and maintain the concentration and efficiency of driving. At the same time, this also provides flexibility for the driver to manually turn off the field of vision follow-up function, that is, even if the vehicle occasionally connects the trailer, the driver can also autonomously select whether to enable the field of vision follow-up function according to actual needs, to adapt to specific driving situations and preferences.

[0100] The technical solutions of the embodiments of the present application will be illustrated below in conjunction with preferred embodiments.

[0101] Figure 2 The schematic diagram of a field of vision follow-up function opening process of a vehicle according to an embodiment of the present application is shown in FIG. 1. Figure 2As shown, after the driver manually turns on the field of view follow-up physical switch, the field of view follow-up function of the rearview mirror can be activated, and then the vehicle controller can transmit an activation signal of the field of view follow-up function, a turn signal of the vehicle and a steering wheel angle signal of the vehicle to the CMS controller. After receiving the above signals, the CMS controller can start an internal algorithm to calculate the above signals, and then control the rearview mirror of the vehicle to timely switch between the default field of view and the temporary field of view according to the calculation result. The default field of view is the original field of view range described above, and the temporary field of view is the target field of view range described above. That is, when the vehicle performs a turning or lane changing operation, the CMS controller can control the field of view display range of the rearview mirror of the vehicle to switch from the default field of view to the temporary field of view, and when the vehicle performs a straight driving operation, the CMS controller can control the field of view display range of the rearview mirror of the vehicle to switch from the temporary field of view to the default field of view.

[0102] Figure 3 FIG. 6 is a flowchart of a field of view follow-up function closing process of a vehicle according to an embodiment of the present application. Figure 3 As shown, after the driver manually turns off the field of view follow-up physical switch, the field of view follow-up function of the rearview mirror can be turned off, and then the vehicle controller can transmit a closing signal of the field of view follow-up function, a turn signal of the vehicle and a steering wheel angle signal of the vehicle to the CMS controller, and the CMS controller can control the rearview mirror of the vehicle to keep the default field of view unchanged after receiving the above signals. That is, when the field of view follow-up function is in the closed state, no matter what operation the vehicle performs or what complex road conditions the vehicle encounters, the CMS controller will keep a stable fixed field of view to avoid unnecessary view angle switching. However, even if the field of view follow-up function is in the closed state, the CMS controller can still obtain the state signal of the vehicle in real time, so that the CMS controller can quickly respond and smoothly transition to the dynamic adjustment mode of the field of view follow-up function after the driver reactivates the field of view follow-up function. This semi-automatic control logic takes into account the direct operation requirements of the driver and makes use of the automation technology of the vehicle, and can meet the requirements of different driving styles and driving scenes.
