s40: detecting whether the current driving condition triggers the visual angle adjustment;
s50: when the current running condition triggers the visual angle adjustment, the display visual angle of the display content of the lane-level environment is adjusted according to the current running condition.
The control method of the embodiment of the present invention may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the in-vehicle terminal 100 is provided to the vehicle 1000. The in-vehicle terminal 100 includes one or more processors 102 and memory 104. The memory 104 stores a computer program that, when executed by the processor 102, implements steps S10, S20, S30, S40, and S50 of the control method described above.
The control method and the vehicle-mounted terminal 100 according to the embodiments of the present invention can adjust the display viewing angle of the lane-level environment display content according to the current driving situation, so that the display modes of the lane-level environment display content can be more diversified. In addition, through the flexible change of the display mode, the displayed lane-level environment display content is more targeted, the information acquisition efficiency of a user can be greatly improved, the user is helped to know the road surface and the surrounding situation in advance or in more detail, and the traffic efficiency and the driving safety are improved.
In particular, the map may be a high-precision map provided by a vendor. The map may include lane-level data, place names, house buildings, natural landscapes, and the like. The lane-level data may include lane data, tunnel data, bridge data, guardrail data, and the like. The map may be stored in the cloud server or in the memory 104 of the local in-vehicle terminal 100, which is not limited herein. In some embodiments, the map is stored in a cloud server, and the vehicle 1000 may connect to the cloud server through a wireless communication manner (such as WIFI, a mobile communication network, etc.), so that the vehicle 1000 obtains lane-level data of the map from the cloud server. In some embodiments, the map is stored in the memory 104 of the local in-vehicle terminal 100, and the vehicle 1000 in turn retrieves lane-level data of the map from the memory 104 of the local in-vehicle terminal 100. It will be appreciated that the lane-level data of the map is static and the environmental data is dynamic.
The vehicle 1000 may include an environmental awareness sensor (not shown). The environmental perception sensor may include a high definition camera, millimeter wave radar, ultrasonic radar, lidar, attitude sensor, positioning sensor, and the like. The context-aware sensor may be disposed around the vehicle 1000. The environmental awareness sensors are capable of acquiring dynamically changing environmental data around the vehicle 1000 in real time. The environmental data of the vehicle 1000 may include nearby pedestrians, location information of nearby pedestrians, nearby vehicles 1000, location information of nearby vehicles 1000, and the like. By processing the electrical signals generated by the environmental awareness sensors, environmental data of the vehicle 1000 may be acquired. In some embodiments, the vehicle 1000 may include a display screen 200, the display screen 200 being capable of displaying lane-level environmental display content at different display perspectives; in some embodiments, the vehicle includes an imaging device (e.g., a projector) capable of displaying the display contents of the lane-level environment at different display viewing angles, and the embodiments and advantageous effects of the control method for the display viewing angle of the display contents of the lane-level environment will be described by taking the vehicle 1000 including the display screen 200 as an example.
Further, the lane-level environmental display content may be generated by fusing the lane-level data and the environmental data. The current driving situation capable of triggering the viewing angle adjustment may include that the distance between the vehicle 1000 and the preset position is smaller than the preset distance, hazard warning is performed, and the vehicle is jammed. After detecting whether the current driving situation triggers the viewing angle adjustment, determining the display viewing angle of the lane-level environment display content according to the current driving situation of the vehicle 1000, and further adjusting the display viewing angle of the lane-level environment display content according to the corresponding display viewing angle. It can be understood that the display modes of the lane-level environment display contents corresponding to different current driving conditions are different. The corresponding relationship between the current running condition and the display mode may be customized by the user and stored in the memory 104 of the cloud server or the local vehicle-mounted terminal 100, or the corresponding relationship between the current running condition and the display mode may be preset by a manufacturer and stored in the memory 104 of the cloud server or the local vehicle-mounted terminal 100, which is not limited herein. In some embodiments, the display view angle may include a view angle size and a view angle, where the view angle may include a left view, a right view, a front view, a rear view, a bird's eye view, or any other angle, and when the angles are the same, the larger the display view angle, the more the display content of the lane-level environment is displayed, the smaller the display view angle, the less the display content of the lane-level environment is displayed, so that the display view angle of the display content of the lane-level environment is adjusted according to the current driving situation, which may be understood as that the display content of the lane-level environment with different view angle sizes and view angle is displayed according to different current driving situations. In addition, in some embodiments, each current driving situation corresponds to a display mode with a fixed viewing angle and a fixed viewing angle; in some embodiments, each current driving situation corresponds to a display mode in which the viewing angle and the viewing angle are dynamically changed.
It should be noted that, in some embodiments, a high-precision map provided by a provider may also be displayed, when the display view angle of the display content of the lane-level environment is adjusted, if the current navigation path changes, the displayed screen is switched from displaying the display content of the lane-level environment to displaying the high-precision map provided by the provider, and after the set duration is reached, the high-precision map provided by the display provider is automatically switched to displaying the display content of the lane-level environment.
It should be noted that, in some embodiments, when the current running situation of the vehicle 1000 includes a plurality of kinds, the display priority of the plurality of current running situations may be defined according to the need. Thus, the preferential display of the special current running condition is ensured. In one example, the current running situation of the vehicle 1000 includes performing danger early warning and vehicle congestion, and the priority of performing the danger early warning in the predefined display priority sequence is greater than the priority of vehicle congestion, so that when the current running situation is determined to be performing the danger early warning and vehicle congestion at the same time, according to the display priority sequence, the display view angle of the display content of the lane-level environment is adjusted in a display mode corresponding to the danger early warning preferentially so as to ensure running safety.
Referring to fig. 4, in some embodiments, step S40 includes:
s42: determining to trigger the viewing angle adjustment when the distance between the vehicle 1000 and the preset position is less than the preset distance;
step S50 includes:
s52: and adjusting the display visual angle of the display content of the lane-level environment in a first preset display mode.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to determine to trigger the viewing angle adjustment when the distance between the vehicle 1000 and the preset position is less than the preset distance, and is configured to adjust the display viewing angle of the lane-level environment display content in the first preset display manner.
In this way, the display view angle of the lane-level environment display content is adjusted in the first preset display mode, so as to meet the requirement of the user on the lane-level environment display content when the distance between the vehicle 1000 and the preset position is smaller than the preset distance.
Specifically, the preset locations may include ramps, intersections, attractions, landmarks, etc. The preset distance may include 10 meters, 50 meters, 100 meters, etc. Further, the first preset display mode may include a first preset viewing angle size and a first preset viewing angle, so that when the current driving situation is that the distance between the vehicle 1000 and the preset position is smaller than the preset distance, the display viewing angle of the lane-level environment display content is adjusted according to the first preset viewing angle size and the first preset viewing angle. In some embodiments, the preset position and the preset distance can be set by the user, so that the use requirements of different users are met.
Referring to fig. 5, in one example, when the distance between the vehicle 1000 and the ramp is less than 50 meters, the angle of view adjustment may be determined to be triggered, and then the lane-level environment display content is displayed in a series of angle of view sizes and angle of view changes, specifically, when the distance between the vehicle 1000 and the preset position is less than the preset distance, the lane-level environment display content of the left view angle, the lane-level environment display content of the left rear view angle, the lane-level environment display content of the right rear view angle and the lane-level environment display content of the right front view angle of the vehicle 1000 are sequentially displayed, and when the lane-level environment display content of the right front view angle is displayed, the display angle of view is the largest, so that the user focuses on the road condition of the ramp.
Referring to fig. 6, in some embodiments, step S52 includes:
s522: and displaying the lane-level environment display content at a first scene view angle, wherein the first scene view angle is larger than a preset scene view angle.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to display the lane-level environmental display content at a first scene angle of view, where the first scene angle of view is greater than the preset scene angle of view.
In this way, when the current driving situation is that the distance between the vehicle 1000 and the preset position is smaller than the preset distance, the display viewing angle of the displayed lane-level environment display content is increased, so that the preset position is displayed more, and the user can know the preset position.
It can be understood that, during the running of the vehicle 1000, when the vehicle 1000 approaches a ramp or an intersection, that is, when the distance between the vehicle 1000 and the ramp or the intersection is smaller than a preset distance, a user needs to pay more attention to the vehicle condition, road condition, etc. of the ramp or the intersection, so that during the running of the vehicle 1000, when the current running condition is determined that the distance between the vehicle 1000 and the preset position is smaller than the preset distance, the triggering view angle adjustment is determined, the lane-level environment display content is displayed with a larger view angle, so that the ramp or the intersection can be displayed in advance, the user can know the front vehicle condition, road condition, etc. in advance, thereby improving the driving experience and ensuring the driving safety. In addition, in the driving process of the vehicle 1000, when the vehicle 1000 approaches a sight spot or a landmark, that is, when the distance between the vehicle 1000 and the sight spot or the landmark is smaller than a preset distance, the triggering of the visual angle adjustment is determined, and the lane-level environment display content is displayed at a larger visual angle, so that the sight spot or the landmark can be displayed in advance, and the user can primarily know the sight spot or the landmark, thereby improving the interestingness.
Referring to fig. 7, in some embodiments, step S40 includes:
s44: when the danger early warning is carried out, determining to trigger the visual angle adjustment;
step S50 includes:
s54: and adjusting the display visual angle of the display content of the lane-level environment in a second preset display mode.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to determine to trigger an adjustment of the viewing angle when performing danger warning, and to adjust the display viewing angle of the display content of the lane-level environment in a second preset display manner.
Therefore, the display view angle of the display content of the lane-level environment is adjusted in a second preset display mode, so that the requirement of a user on the display content of the lane-level environment when dangerous early warning is carried out is met.
Specifically, in certain embodiments, the hazard pre-warning may include forward collision pre-warning (forward collision warning, FCW), automatic emergency braking (automatic emergency braking, AEB), rear collision pre-warning (rear collision warning, RCW), blind zone monitoring (blind changing warning, BSD), door opening pre-warning (door open warning, DOW), lane departure pre-warning (lane departure warning, LDW), and the like. The second preset display mode may include a second preset viewing angle size and a second preset viewing angle.
Further, in the driving process of the vehicle 1000, when any one of the pre-warnings FCW, AEB, RCW, BSD, DOW, LDW is triggered, the triggering of the viewing angle adjustment can be determined, and then the display viewing angle of the lane-level environment display content can be adjusted according to the second preset viewing angle and the second preset viewing angle.
Referring to fig. 8, in some embodiments, step S54 includes:
s542: and displaying the lane-level environment display content at a second scene view angle, wherein the second scene view angle is smaller than the preset scene view angle.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to display the lane-level environmental display content at a second scene angle, which is smaller than the preset scene angle.
In this way, when the current driving situation is danger early warning, the scene view angle of the displayed lane-level environment display content is reduced, so that the driving road surface near the vehicle 1000 and the surrounding situation thereof are displayed more, and the user can know the danger early warning more intuitively.
It can be understood that, in the driving process, when any one of the pre-warnings FCW, AEB, RCW, BSD, DOW, LDW is triggered, the user needs to know more environmental data of the vehicles 1000 such as the nearby pedestrians, the nearby pedestrian position information, the nearby vehicle 1000 position information, and the like, so when the current driving situation is danger pre-warning, the trigger visual angle adjustment is determined, the lane-level environmental display content is displayed at a smaller visual angle, and thus the environmental data of the vehicles 1000 such as the nearby pedestrians, the nearby pedestrian position information, the nearby vehicle 1000 position information, and the like can be displayed more clearly, so that the user can know the external environment conveniently, and the driving safety is improved.
Referring to fig. 9, in some embodiments, step S40 includes:
s46: when the vehicle is congested, determining to trigger the visual angle adjustment;
step S50 includes:
s56: and adjusting the display visual angle of the display content of the lane-level environment in a third preset display mode.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to determine to trigger the viewing angle adjustment when the vehicle is congested, and is configured to adjust the display viewing angle of the lane-level environment display content in a third preset display manner.
Therefore, the display view angle of the display content of the lane-level environment is adjusted in a third preset display mode, so that the requirement of a user on the display content of the lane-level environment when the vehicle is jammed is met.
Specifically, in some embodiments, vehicle congestion may be determined when the number of nearby other vehicles 1000 exceeds a preset number and/or the speed of the own vehicle 1000 is below a preset speed. In some embodiments, whether vehicle congestion occurs may be determined based on visual identification, cloud data, vehicle-to-outside information exchange (vehicle to everything, V2X), and the like. The third preset display mode may include a third preset viewing angle size and a third preset viewing angle, so that when the viewing angle adjustment is triggered, the lane-level environment display content is displayed with the third preset viewing angle size and the third preset viewing angle.
Referring to fig. 10, in some embodiments, step S56 includes:
s562: and displaying the lane-level environment display content at a third scene view angle, wherein the third scene view angle is larger than the preset scene view angle.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to display the lane-level environmental display content at a third scene angle, which is greater than the preset scene angle.
Therefore, when the current driving condition is vehicle congestion, the scene view angle of the displayed lane-level environment display content is increased, so that the vehicle congestion condition is displayed more, and a user can know the vehicle congestion condition more intuitively.
It can be understood that in the driving process, when the vehicle is congested, the user usually pays more attention to the congestion condition of the front road section, so when the current driving condition is that the vehicle is congested, the trigger visual angle adjustment is determined, the lane-level environment display content is displayed at a larger visual angle, thus the congestion condition of the front road section can be intuitively displayed, the user can conveniently know the environment outside the vehicle, and the driving is assisted.
Referring to fig. 11, in some embodiments, the control method further includes:
s60: when the current driving condition does not trigger the viewing angle adjustment, the running state of the vehicle 1000 is acquired and the display viewing angle of the lane-level environment display content is controlled according to the running state.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to obtain an operation state of the vehicle 1000 and control a display viewing angle of the lane-level environment display content according to the operation state when the current driving situation does not trigger the viewing angle adjustment.
In this way, when the current driving situation is that the viewing angle adjustment is not triggered, the lane-level environment display content is displayed in a display mode corresponding to the running state according to the running state of the vehicle 1000, so that the display modes of the lane-level environment display content are more diversified.
Specifically, the running state of the vehicle 1000 may include at least one of a driving mode of the vehicle 1000, a steering state, and a running speed of the vehicle 1000. The driving modes of the vehicle 1000 may include an automatic navigation assistance (Navigation Guided Pilot, NGP) driving mode and a non-NGP driving mode. The steering states may include a no steering state, a left steering state, and a right steering state. The running speed of the vehicle 1000 may be in a first speed range or a second speed range, the minimum speed of the first speed range being greater than the maximum speed of the second speed range.
Further, in some embodiments, when the running state of the vehicle 1000 includes any one of a driving mode, a steering state, and a running speed of the vehicle 1000, one driving mode corresponds to one display mode, one steering state corresponds to one display mode, and each speed range in which the running speed of the vehicle 1000 is located corresponds to one display mode, so that when the current running condition does not trigger the viewing angle adjustment, any one of the driving mode, the steering state, and the running speed of the vehicle 1000 is acquired, and the display viewing angle of the lane-level environment display content is controlled in the display mode corresponding to the any one of the driving mode, the steering state, or the running speed of the vehicle 1000. In one example, when the current driving mode is an NGP driving mode, displaying the lane-level environment display content at a fourth scene view angle; when the current driving mode is a non-NGP driving mode, displaying the lane-level environment display content with a preset scene view angle, wherein the fourth scene view angle is smaller than the preset scene view angle, so that the lane-level environment display content is displayed with different display view angles according to the driving mode, and the requirement of a user on the lane-level environment display content in different driving modes is met. In one example, the display view is focused on the current lane of travel of the vehicle 1000 when the current steering state is a no-steering state; when the current steering state is a left steering state, the display view angle focuses on a lane on the left of the current traveling lane of the vehicle 1000; when the current steering state is the right steering state, the display view angle focuses on the right lane of the current driving lane of the vehicle 1000, so that the lane-level environment display content is displayed at the display view angle corresponding to the no-steering state, the left steering state or the right steering state, so as to meet the requirement of the user on the lane-level environment display content in the no-steering state, the left steering state and the right steering state. In one example, when the current travel speed is in the first speed range, displaying lane-level environmental display content at a fifth scene view angle; and when the current running speed is in the second speed range, displaying the lane-level environment display content at a sixth scene view angle, wherein the fifth scene view angle is larger than the sixth scene view angle, so that the lane-level environment display content is displayed at different display view angles according to the running speed, and the requirement of a user on the lane-level environment display content at different running speeds is met. It can be appreciated that at different driving speeds, the display content of the lane-level environment that the user needs to know is different, for example, at a higher driving speed, the user needs to know the display content of the lane-level environment at a far place more so as to select a proper driving route; at lower driving speeds, the user is more required to learn about the close lane-level environmental display content to maintain a proper safe distance.
In some embodiments, when the running state of the vehicle 1000 includes any two of the driving mode, the steering state, and the running speed of the vehicle 1000, the combination state of one driving mode-steering state corresponds to one display mode, the combination state of one driving mode-running speed corresponds to one display mode, and the combination state of one steering state-running speed corresponds to one display mode, so that when the current running condition does not trigger the viewing angle adjustment, any two of the driving mode, the steering state, and the running speed of the vehicle 1000 are acquired, and the lane-level environment display contents are displayed in the display viewing angles corresponding to the any two driving modes, the steering state, or the running speed of the vehicle 1000.
In some embodiments, when the running state of the vehicle 1000 includes all of the driving mode, the steering state, and the running speed of the vehicle 1000, one driving mode-steering state-running speed combined state corresponds to one display mode, so that when the current running condition does not trigger the viewing angle adjustment, the driving mode, the steering state, and the running speed of the vehicle 1000 are acquired, and the lane-level environment display contents are displayed at the display viewing angles corresponding to the driving mode, the steering state, and the running speed of the vehicle 1000. For example, during running of the vehicle 1000, when it is determined that the current driving mode is the automatic navigation assist driving mode and the current steering state is the no-steering state and the current running speed is in the first speed range, the lane-level environment display content is displayed at the seventh scene view angle and the display view angle is focused on the current running lane of the vehicle 1000; further, as the vehicle 1000 travels, when it is determined that the current driving mode is the automatic navigation assist driving mode and the current steering state is the no-steering state and the current traveling speed is in the second speed range, switching from the seventh scene view angle to an eighth scene view angle, which is smaller than the seventh scene view angle, to display the contents of the lane-level environment display and the display view angle is focused on the current traveling lane of the vehicle 1000; further, as the vehicle 1000 travels, when it is determined that the current driving mode is the non-automatic navigation-assisted driving mode and the current steering state is the no-steering state and the current traveling speed is in the second speed range, switching from the eighth scene view angle to the ninth scene view angle to display the contents of the lane-level environment display and the display view angle is focused on the current traveling lane of the vehicle 1000, the ninth scene view angle being larger than the eighth scene view angle; further, as the vehicle 1000 travels, when it is determined that the current driving mode is the non-automatic navigation-assisted driving mode and the current steering state is the no-steering state and the current traveling speed is in the first speed range, switching from the ninth scene view angle to a tenth scene view angle displaying the contents of the lane-level environment display and the display view angle focusing on the current traveling lane of the vehicle 1000, the tenth scene view angle being larger than the ninth scene view angle; further, as the vehicle 1000 travels, when it is determined that the current driving mode is the automatic navigation assist driving mode and the current steering state is the no-steering state and the current traveling speed is in the first speed range, switching from the tenth scene view angle to the seventh scene view angle displaying the lane-level environment display content and the display view angle focusing on the current traveling lane of the vehicle 1000, the seventh scene view angle being smaller than the tenth scene view angle.
It should be noted that, in some embodiments, when the current driving situation is that the distance between the vehicle 1000 and the preset position is smaller than the preset distance, the danger warning is performed, or the vehicle is jammed, the display mode may be further determined according to the running state of the vehicle 1000, and the display view angle of the display content of the lane-level environment may be adjusted according to the newly determined display mode. Therefore, the display modes of the display contents of the lane-level environment are more diversified. Specifically, a combination state in which the distance between the vehicle 1000 and the preset position is smaller than the preset distance-the running state corresponds to a display mode, a combination state in which hazard warning-the running state is performed corresponds to a display mode, and a combination state in which the vehicle is jammed-the running state corresponds to a display mode. In one example, the running states include an NGP driving mode and a non-NGP driving mode, and when it is confirmed that the distance between the vehicle 1000 and the preset position is smaller than the preset distance and the running state is the NGP driving mode in the current running condition, the display view angle of the display content of the lane-level environment is adjusted according to the eleventh scene view angle; further, as the vehicle 1000 travels, when it is confirmed that the current traveling condition is that the distance between the vehicle 1000 and the preset position is smaller than the preset distance and the running state is the non-NGP driving mode, the display view angle of the lane-level environment display content is adjusted with the twelfth scene view angle, the eleventh scene view angle is larger than the twelfth scene view angle, and the twelfth scene view angle is larger than the preset scene view angle. In another example, the operating state includes the travel speed being in a first speed range and the travel speed being in a second speed range, a minimum speed of the first speed range being greater than a maximum speed of the second speed range. When the current running condition is confirmed to be dangerous early warning and the current running speed is in the first speed range in the running process of the vehicle 1000, the display view angle of the display content of the lane-level environment is adjusted according to the thirteenth scene view angle; further, as the vehicle 1000 travels, when it is confirmed that the current traveling condition is to perform hazard warning and the current traveling speed is in the second speed range, the display view angle of the lane-level environment display content is adjusted with a thirteenth scene view angle, which is greater than the fourteenth scene view angle, which is greater than the preset scene view angle.
Referring to fig. 12, in some embodiments, the control method further includes:
s70: when receiving an adjustment signal input by a user, displaying lane-level environment display content at a display view angle corresponding to the adjustment signal;
s80: and when the adjustment signal is not received within the preset time, adjusting the display visual angle of the display content of the lane-level environment according to the current running condition.
The control method of the above embodiment may be implemented by the in-vehicle terminal 100 of the embodiment of the present invention. Specifically, the processor 102 is configured to display the lane-level environment display content at a display viewing angle corresponding to the adjustment signal when receiving the adjustment signal input by the user, and is configured to adjust the display viewing angle of the lane-level environment display content according to the current driving situation when not receiving the adjustment signal within a preset duration.
Therefore, according to the adjustment signal, the lane-level environment display content is displayed at different display view angles, so that the requirement of a user on the lane-level environment display content under different conditions is met. Meanwhile, driving safety and controllable display content are ensured. It can be appreciated that during the driving of the vehicle 1000, the system safety-related prompt is generally based on the preset display view angle of the display screen 200, and if the display screen 200 displays the user-defined picture of the non-preset display view angle for a long time, the system safety-related prompt cannot be reminded, so that the driving safety cannot be guaranteed.
Specifically, the adjustment signal may include an enlarged view angle, a reduced view angle, an angle adjustment, and the like, and the angle adjustment may include a left view, a right view, a front view, a rear view, a bird's eye view, or any other angle, and further, when the adjustment signal of the enlarged view angle is received, the view angle of the displayed lane-level environment display content is increased; when receiving the adjustment signal of the reduced visual angle, reducing the visual angle of the displayed lane-level environment display content; and when receiving an adjusting signal for adjusting the angle, adjusting the angle of the displayed lane-level environment display content.
The adjustment signal may be input by a touch gesture, a voice input, or a space gesture. The touch gesture may include double-finger open, double-finger close, double-finger long press, double-finger drag, single-finger single click, single-finger double click, single-finger long press, single-finger drag, etc. The space gesture may include five-finger separation, five-finger convergence, palm rotation, and the like. For example, the user performs a single-finger double-click on the display screen 200 to input an adjustment signal for reducing the viewing angle; the user performs a single-finger long-press of an adjustment signal capable of inputting viewing angle amplification on the display screen 200; the user performs single-finger dragging on the display screen 200 to input an angle-adjustable adjustment signal; the user can input an adjusting signal for amplifying the visual angle by separating five fingers at a spacing in front of the camera; the user can input an adjusting signal for reducing the visual angle by gathering five fingers at intervals in front of the camera; the user rotates the palm at intervals in front of the camera to input an adjusting signal for adjusting the angle; the user speaks "display left view", "display right view", "display front view", "display rear view", "display bird's eye view" loudly, and can input an adjustment signal for adjusting the angle.
Further, the preset duration may be 4 seconds, 5 seconds, 6 seconds, etc. In one example, when the preset duration is 5 seconds, that is, when the adjustment signal is not received within 5 seconds, the display view angle of the display content of the lane-level environment is adjusted according to the current driving situation, so that driving safety can be better ensured, and the display content is controllable.
It should be noted that the above explanation of the control method and the embodiment and advantageous effects of the in-vehicle terminal 100 are also applicable to the vehicle 1000, and are not developed in detail here to avoid redundancy.
