[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] In one embodiment, Figure 1 As shown, a method for switching the mode of an in-vehicle interface is provided. This embodiment takes the method applied to a controller as an example. The controller is a component in a vehicle, specifically a body controller. It is understandable that the vehicle can be a vehicle, a robot device with a driving function, etc. The vehicle can be a truck, an off-road vehicle, a dump truck, a tractor, a special-purpose vehicle, a bus, a car, a semi-trailer, etc. The body controller and the in-vehicle interface are connected and communicated via the in-vehicle CAN bus. In this embodiment, the method includes the following steps:

[0062] Step 102, obtaining vehicle status information corresponding to the target vehicle, where the vehicle status information includes at least one of environmental information, position information, and vehicle light status information.

[0063] Optionally, multiple vehicle-mounted devices or systems such as sensors, lighting systems, and GPS systems (Global Positioning System, GPS for short) installed on the target vehicle can detect multiple status data of the target vehicle in real time to obtain vehicle status information. For example, an optical rain sensor detects the rainfall outside the vehicle in real time as environmental information; GPS detects the current road information in real time, including but not limited to the road name and road location; and the lighting system detects whether the headlights are turned on in real time.

[0064] It should be noted that: First, the different brightness of light caused by different surrounding environments of the vehicle will cause the driver to experience visual fatigue and other discomfort such as glare and reflection. Second, the driver will perform different interface operations in different usage scenarios, and the driver's operation requirements are different in different environments and road conditions. Third, changes in the surrounding weather cause changes in the atmosphere inside the car, affecting the driver's mood. The traditional human-machine interaction (HMI) strategy can no longer meet the needs of drivers. Considering the convenience of the driver's screen touch operation and visual experience, a vehicle interface mode switching method is adopted. The vehicle interface (UI) will make different intelligent linkages with the changes in the scene, environment, weather, etc. as the vehicle travels, and automatically change the vehicle interface display (UI) style to improve the driver's driving safety, simplicity of operation, visual comfort and intelligence.

[0065] Step 104: Generate at least one digital signal according to the vehicle status information.

[0066] Optionally, multiple on-board devices or on-board systems on the target vehicle each generate a digital signal based on their respective data detection results, and the controller collects the digital signals generated by all on-board devices or on-board systems.

[0067] Step 106: determining a target digital signal from the digital signals according to the signal priorities of the digital signals.

[0068] Optionally, the controller is pre-configured with signal priority levels of various digital signals. After collecting digital signals fed back from all vehicle-mounted devices or vehicle-mounted systems, the controller identifies the digital signal with the highest signal priority as the target digital signal.

[0069] Step 108 , generating a target mode instruction corresponding to the target digital signal according to the target digital signal, wherein the target mode instruction is used to control the vehicle-mounted interface of the target vehicle to perform corresponding mode switching.

[0070] Among them, the in-vehicle interface refers to the display screen of the in-vehicle human-computer interaction equipment, such as instruments, in-vehicle information service terminals (i.e. in-vehicle navigation or in-vehicle central control screen), in-vehicle radar image display screen, etc.

[0071] Optionally, the controller or the vehicle-mounted human-computer interaction device is pre-configured with vehicle-mounted interface display modes corresponding to various digital signals. After determining the target digital signal, the controller may further determine the vehicle-mounted interface display mode that matches the target digital signal, generate a corresponding target mode instruction and send it to the vehicle-mounted human-computer interaction device. Alternatively, the controller may directly transmit the target digital signal to the vehicle-mounted human-computer interaction device, and after determining the target digital signal, the vehicle-mounted human-computer interaction device may further determine the vehicle-mounted interface display mode that matches the target digital signal, and generate a corresponding target mode instruction to control its own display screen to switch the display mode. The target digital signal may be sent to the vehicle-mounted human-computer interaction device at the same time to control all vehicle-mounted display screens to switch to the corresponding display mode, or it may be sent to at least one designated vehicle-mounted human-computer interaction device to control only at least one vehicle-mounted display screen to switch to the corresponding display mode.

[0072] In the above-mentioned vehicle interface mode switching method, the vehicle status information corresponding to the target vehicle is obtained, and the vehicle status information includes at least one of environmental information, position information and vehicle light status information; at least one digital signal is generated according to the vehicle status information; a target digital signal is determined from each digital signal according to the signal priority of each digital signal; and a target mode instruction corresponding to the target digital signal is generated according to the target digital signal, and the target mode instruction is used to control the vehicle interface of the target vehicle to perform corresponding mode switching. By identifying the vehicle equipment status information, the road conditions of the vehicle and the external environment, a display mode that can adapt to the current situation is selected based on multiple factors inside and outside the vehicle, and the vehicle interface is automatically switched to this display mode, which greatly improves the interaction mode and flexibility of human-computer interaction.

[0073] In one embodiment, obtaining vehicle status information corresponding to the target vehicle includes: obtaining environmental information of the target vehicle through an optical rain sensor; obtaining location information of the target vehicle through a global positioning system; and obtaining headlight status information of the target vehicle through a vehicle lighting system.

[0074] In some embodiments, Figure 2 As shown in the figure, an intelligent linkage is achieved between the vehicle and the vehicle interface. The body controller (BCM) collects analog signals from the optical rain sensor, GPS and lighting system, including optical rain sensor signals, GPS location signals and small light on / off signals. The body controller converts the collected analog signals into digital signals and transmits them to the gateway CAN bus. The CAN bus summarizes the multiple digital signals received and transmits them to the instrument or vehicle information service terminal. The instrument or vehicle information service terminal calls the corresponding interface mode according to the multiple digital signals received to adapt to the current vehicle usage environment.

[0075] In this embodiment, the environment information of the target vehicle is obtained through the optical rain sensor; the location information of the target vehicle is obtained through the global positioning system; and the headlight status information of the target vehicle is obtained through the vehicle lighting system. It is possible to detect a variety of vehicle status information such as vehicle equipment status, environmental conditions and road conditions, and jointly determine the display mode of the vehicle interface.

[0076] In one embodiment, at least one digital signal is generated based on vehicle status information, including: obtaining environmental parameters based on environmental information, the environmental parameters being used to characterize rainfall; generating a first digital signal when the environmental parameters are less than an environmental threshold; or generating a second digital signal when the environmental parameters are not less than the environmental threshold; obtaining road markings based on location information; generating a first digital signal when the road marking is a first marking; or generating a third digital signal when the road marking is a second marking; the first marking is used to characterize normal road conditions, and the second marking is used to characterize abnormal road conditions; generating a first digital signal when the headlight status information is that the headlights are off; or generating a fourth digital signal when the headlight status information is that the headlights are on.

[0077] Among them, the road mark is a road condition label added to the road in advance through the GPS system. If the road condition of a road is good, a first mark can be added to it. If the road condition of a road is poor, a second mark can be added to it. The second mark can also include multiple sub-markers, each seed mark represents a type of poor road condition. For example, the second mark includes three sub-markers, corresponding to bumpy roads, roads with damaged pavement, and sharp turns.

[0078] Optionally, environmental information can be represented by rainfall, and vehicle light status information can be determined by the on / off status of the small lights. The small lights refer to the vehicle's clearance lights, also called width lights. The environmental threshold is pre-set as M1 in the controller, and the second mark includes a bumpy path F1, a bad path F2, a sharp turn path F3, etc.

[0079] The optical rain sensor signal currently collected by the controller is Mx;

[0080] ①When Mx<M1, the analog quantity is converted into a digital signal and output as N1;

[0081] ②When Mx≥M1, the analog quantity is converted into a digital signal output as N2.

[0082] The GPS position signal currently collected by the controller is Fx;

[0083] ①When Fx≠F1 and Fx≠F2 and Fx≠F3..., the analog quantity is converted into a digital signal and output as N1;

[0084] ②When Fx=F1 or Fx=F2 or Fx=F3......, the analog quantity is converted into digital signal output as N3.

[0085] The controller currently collects the small light signal Qx, the small light off signal Q1, and the small light on signal Q2;

[0086] ①When Qx=Q1, the digital signal output is N1;

[0087] ②When Qx=Q2, the digital signal output is N4.

[0088] N1 represents a first digital signal, N2 represents a second digital signal, N3 represents a third digital signal, and N4 represents a fourth digital signal.

[0089] In this embodiment, environmental parameters are obtained based on environmental information, and the environmental parameters are used to characterize rainfall; when the environmental parameters are less than the environmental threshold, a first digital signal is generated; or, when the environmental parameters are not less than the environmental threshold, a second digital signal is generated; road markings are obtained based on location information; when the road markings belong to the first markings, a first digital signal is generated; or, when the road markings belong to the second markings, a third digital signal is generated; the first marking is used to characterize normal road conditions, and the second marking is used to characterize abnormal road conditions; when the vehicle light status information is that the vehicle light is off, a first digital signal is generated; or, when the vehicle light status information is that the vehicle light is on, a fourth digital signal is generated. Multiple digital signals can be generated respectively according to a variety of vehicle status information such as vehicle equipment status, environmental conditions, and road conditions, and each digital signal can be subsequently integrated to determine the display mode of the vehicle interface.

[0090] In one embodiment, the signal priorities of the digital signals are, from high to low, the fourth digital signal, the third digital signal, the second digital signal, and the first digital signal. According to the signal priorities of the digital signals, a target digital signal is determined from the digital signals, including: selecting a digital signal with the highest corresponding signal priority as the target digital signal.

[0091] Optionally, the controller pre-sets the signal priority of the digital signal, and each time after acquiring multiple digital signals, the target digital signal is determined according to the signal priority. For example, when the three digital signals acquired are the first digital signal, the first digital signal and the third digital signal, the target digital signal is the third digital signal.

[0092] In this embodiment, a digital signal with the highest corresponding signal priority is selected as the target digital signal. Each digital signal can be integrated to determine the display mode of the vehicle interface, and ensure that the display mode is suitable for the current vehicle state, road conditions and environmental conditions.

[0093] In one embodiment, a target mode instruction corresponding to the target digital signal is generated according to the target digital signal, including: when the target digital signal is a first digital signal, a normal mode instruction is generated; when the target digital signal is a second digital signal, a cloudy mode instruction is generated; when the target digital signal is a third digital signal, an extreme path mode instruction is generated; when the target digital signal is a fourth digital signal, a dark sky mode instruction is generated.

[0094] Optionally, the instrument and the in-vehicle information service terminal can freely set a variety of interface mode styles corresponding to different digital signals before leaving the factory, so as to achieve more interface switching effects and realize the intelligent linkage effect of the in-vehicle interface (UI) based on more scenarios. N1 is used to represent the first digital signal, N2 is used to represent the second digital signal, N3 is used to represent the third digital signal, and N4 is used to represent the fourth digital signal.

[0095] The instrument generates a mode command based on the received digital signal to switch the interface mode of the vehicle interface (UI). Figure 3 As shown, the vehicle-mounted interface (UI) of the instrument is set with 4 interface style modes, and different style modes corresponding to different instructions are switched.

[0096] ①N1 corresponds to interface mode 1: normal mode;

[0097] ②N2 corresponds to interface mode 2: cloudy mode;

[0098] ③N3 corresponds to interface mode 3: extreme path mode;

[0099] ④N4 corresponds to interface mode 4: dark mode.

[0100] The in-vehicle information service terminal generates a mode instruction according to the received digital signal to switch the interface mode of the in-vehicle information service terminal interface (UI). Figure 4 As shown, the vehicle-mounted interface (UI) of the vehicle-mounted information service terminal is set with 4 interface style modes, and different style modes corresponding to different instructions are switched.

[0101] ①N1 corresponds to interface mode 1: normal mode;

[0102] ②N2 corresponds to interface mode 2: cloudy mode;

[0103] ③N3 corresponds to interface mode 3: extreme path mode;

[0104] ④N4 corresponds to interface mode 4: dark mode.

[0105] In this embodiment, by generating a normal mode instruction when the target digital signal is the first digital signal; generating a cloudy mode instruction when the target digital signal is the second digital signal; generating an extreme path mode instruction when the target digital signal is the third digital signal; and generating a dark sky mode instruction when the target digital signal is the fourth digital signal, a display mode that can adapt to the current situation can be selected by comprehensively considering multiple factors inside and outside the vehicle, and the vehicle interface can be automatically switched to the display mode.

[0106] In one embodiment, after generating a target mode instruction corresponding to the target digital signal according to the target digital signal, it also includes: obtaining the power-on status of the on-board human-computer interaction device of the target vehicle; when the on-board human-computer interaction device is turned on, sending the target mode instruction to the on-board human-computer interaction device; the target mode instruction is used to control the interaction interface of the on-board human-computer interaction device to switch to the interface mode corresponding to the target mode instruction; and returning to execute the step of obtaining the vehicle status information corresponding to the target vehicle.

[0107] Among them, vehicle-mounted human-computer interaction equipment specifically refers to vehicle-mounted electronic equipment with display function, including but not limited to instruments, vehicle-mounted information service terminals, blind spot imaging systems, etc.

[0108] Optionally, if the vehicle-mounted human-computer interaction device is not turned on, it means that the vehicle-mounted interface is not working, and there is no need to switch the interface mode. After a preset time interval, the controller reacquires the vehicle status information, determines a new target digital signal and a target mode command, and detects the power-on status of the vehicle-mounted human-computer interaction device again.

[0109] In this embodiment, by obtaining the power-on status of the vehicle-mounted human-machine interaction device of the target vehicle; when the vehicle-mounted human-machine interaction device is powered on, sending a target mode instruction to the vehicle-mounted human-machine interaction device; the target mode instruction is used to control the interactive interface of the vehicle-mounted human-machine interaction device to switch to the interface mode corresponding to the target mode instruction; and returning to execute the step of obtaining the vehicle status information corresponding to the target vehicle. The interface mode can be automatically switched when the vehicle-mounted human-machine interaction device is powered on, thereby reducing resource consumption.

[0110] In one embodiment, a vehicle interface mode switching method, such as Figure 5 As shown, taking the interface mode applied to switch the in-vehicle information service terminal as an example, it includes:

[0111] BCM obtains the environmental information of the target vehicle through the optical rain sensor, the location information of the target vehicle through the global positioning system, and the headlight status information of the target vehicle through the vehicle lighting system.

[0112] The BCM obtains environmental parameters based on environmental information, and the environmental parameters are used to characterize rainfall; when the environmental parameters are less than the environmental threshold, a first digital signal is generated; or, when the environmental parameters are not less than the environmental threshold, a second digital signal is generated. The BCM obtains road markings based on location information; when the road markings belong to the first markings, a first digital signal is generated; or, when the road markings belong to the second markings, a third digital signal is generated; the first marking is used to characterize normal road conditions, and the second marking is used to characterize abnormal road conditions. The BCM generates a first digital signal when the vehicle light status information indicates that the vehicle light is off; or, when the vehicle light status information indicates that the vehicle light is on, a fourth digital signal is generated.

[0113] BCM selects a digital signal with the highest corresponding signal priority as the target digital signal. The signal priorities of the digital signals are the fourth digital signal, the third digital signal, the second digital signal and the first digital signal from high to low. BCM analyzes whether the target digital signal meets the switching conditions. If the switching conditions are not met, the interface mode of the vehicle information service terminal remains unchanged, and the environmental information, location information and vehicle light status information are re-acquired. For example, if the current target digital signal is the first digital signal, and the interface mode of the vehicle information service terminal is already in normal mode, the switching conditions are not met.

[0114] If the switching condition is met, the BCM generates a target mode command corresponding to the target digital signal according to the target digital signal and transmits it to the CAN bus. The target mode command is used to control the vehicle interface of the target vehicle to switch the corresponding mode. When the target digital signal is the first digital signal, a normal mode command is generated; when the target digital signal is the second digital signal, a cloudy mode command is generated; when the target digital signal is the third digital signal, an extreme path mode command is generated; when the target digital signal is the fourth digital signal, a dark sky mode command is generated.

[0115] When the vehicle information service terminal is powered on, the CAN bus transmits the target mode command to the vehicle information service terminal; the target mode command is used to control the interactive interface of the vehicle information service terminal to switch to the interface mode corresponding to the target mode command; and the step of obtaining environmental information, location information and vehicle light status information is returned. When the vehicle information service terminal is not powered on, the CAN bus does not transmit the target mode command to the vehicle information service terminal.

[0116] In one embodiment, a vehicle interface mode switching method, such as Figure 6 As shown, taking the interface mode applied to switching instruments as an example, it includes:

[0117] BCM obtains the environmental information of the target vehicle through the optical rain sensor, the location information of the target vehicle through the global positioning system, and the headlight status information of the target vehicle through the vehicle lighting system.

[0118] The BCM obtains environmental parameters based on environmental information, and the environmental parameters are used to characterize rainfall; when the environmental parameters are less than the environmental threshold, a first digital signal is generated; or, when the environmental parameters are not less than the environmental threshold, a second digital signal is generated. The BCM obtains road markings based on location information; when the road markings belong to the first markings, a first digital signal is generated; or, when the road markings belong to the second markings, a third digital signal is generated; the first marking is used to characterize normal road conditions, and the second marking is used to characterize abnormal road conditions. The BCM generates a first digital signal when the vehicle light status information indicates that the vehicle light is off; or, when the vehicle light status information indicates that the vehicle light is on, a fourth digital signal is generated.

[0119] BCM selects a digital signal with the highest corresponding signal priority as the target digital signal. The signal priorities of the digital signals are the fourth digital signal, the third digital signal, the second digital signal and the first digital signal from high to low. BCM analyzes whether the target digital signal meets the switching conditions. If the switching conditions are not met, the interface mode of the instrument remains unchanged, and the environmental information, location information and vehicle light status information are re-acquired. For example, if the current target digital signal is the first digital signal, and the interface mode of the instrument is already in normal mode, the switching conditions are not met.

[0120] If the switching condition is met, the BCM generates a target mode command corresponding to the target digital signal according to the target digital signal and transmits it to the CAN bus. The target mode command is used to control the vehicle interface of the target vehicle to switch the corresponding mode. When the target digital signal is the first digital signal, a normal mode command is generated; when the target digital signal is the second digital signal, a cloudy mode command is generated; when the target digital signal is the third digital signal, an extreme path mode command is generated; when the target digital signal is the fourth digital signal, a dark sky mode command is generated.

[0121] When the instrument is powered on, the CAN bus transmits the target mode command to the instrument; the target mode command is used to control the interactive interface of the instrument to switch to the interface mode corresponding to the target mode command; and returns to execute the steps of obtaining environmental information, location information and vehicle light status information. When the instrument is not powered on, the CAN bus does not transmit the target mode command to the instrument.

[0122] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
