DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with 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 of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work falls within the scope of protection of the present application.

[0025] First, the application scenarios to which this application is applicable are introduced. This application can be applied in the field of vehicle display control technology.

[0026] In order to ensure that the vehicle can travel in different scenarios, the driving mode of a general vehicle can be divided into road mode and crossing mode; during the vehicle control process, the power domain control signal is used to drive the road mode; the chassis domain control signal is used to control the crossing mode; through different control modes, the vehicle can better adapt to different driving scenarios, thereby improving the driving experience of the vehicle driver.

[0027] If the power domain control signal and / or chassis domain control signal is lost after the vehicle is powered on, the display of the crossing mode, highway mode and the constant display card may be confused, resulting in errors in the displayed information on the vehicle display screen, which in turn causes the driver to be unable to accurately understand the vehicle information, resulting in vehicle control errors, affecting the driver's driving accuracy and driving experience.

[0028] Based on this, an embodiment of the present application provides a method for displaying a vehicle driving mode to improve the driver's driving accuracy and driving experience.

[0029] See also Figure 1 , Figure 1 This is a flow chart of a method for displaying a vehicle driving mode provided in an embodiment of the present application. Figure 1 As shown in , the method for displaying the vehicle driving mode provided in an embodiment of the present application includes: S101. During the vehicle power-on process, when the vehicle is not in the crossing mode, based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal, determine the first display information of the vehicle display screen.

[0030] S102. When the vehicle is in the crossing mode, the second display information of the vehicle display screen is determined based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal.

[0031] The method for displaying the vehicle driving mode provided in the embodiment of the present application can determine different display information in different situations during the vehicle power-on process based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal, as well as the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal. It can control the vehicle display screen to accurately display vehicle parameter information, provide an accurate reference for the driver's operation, and thereby improve the driver's driving accuracy and driving experience.

[0032] The following describes the exemplary steps of the embodiment of the present application: S101. During the vehicle power-on process, when the vehicle is not in the crossing mode, based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal, determine the first display information of the vehicle display screen.

[0033] In a possible implementation, in order to ensure that the vehicle can travel in different scenarios, the driving mode of a general vehicle can be divided into a highway mode and a crossing mode.

[0034] Specifically, the highway mode is suitable for driving scenarios on paved roads, cities / highways; the crossing mode is suitable for driving scenarios on unpaved roads (for example, deserts, mud, rocks, etc.).

[0035] Generally, the power domain control signal is used to drive the highway mode; the chassis domain control signal is used to control the crossing mode; specifically, the functional module of the highway mode is front-wheel drive / rear-wheel drive priority and linear throttle response; the functional module of the crossing mode is forced four-wheel drive + differential lock and aggressive throttle curve; through different control modes, the vehicle can better adapt to different driving scenarios, thereby improving the driving experience of the vehicle driver.

[0036] In one possible implementation, in order for the driver to always have abreast of various parameter information of the vehicle during driving, a variety of driving information can be displayed on the vehicle display screen. In general driving scenarios, the vehicle display screen displays a permanent display card, which includes a highway mode card, and the vehicle status information is displayed in the permanent display card.

[0037] For example, see Figure 2 , Figure 2 This is a schematic diagram of the display content of the vehicle constant display card provided in the embodiment of the present application, such as Figure 2 As shown, the constant display card 210 is displayed below the vehicle display screen, and the display content includes energy consumption information 211, multimedia information 212, navigation information 213, tire pressure information 214, driving mode information 215 (highway mode), speed and water temperature information 216, etc., providing the driver with a variety of vehicle information parameters to ensure that the driver has a grasp of the vehicle operating parameters and accurately completes the control of the vehicle, which helps to improve the driver's driving experience.

[0038] In another possible implementation, if the current vehicle is in the crossing mode, it is necessary to display the crossing mode card 310 on the vehicle display screen, and display the vehicle information in the crossing mode on the crossing mode card.

[0039] For example, see Figure 3 , Figure 3 This is a schematic diagram of the display content of the vehicle crossing mode card provided in the embodiment of the present application, such as Figure 3 As shown, after determining that the current vehicle is switched to the crossing mode, if the highway mode card in the usual display card is not currently displayed, the preset position of the vehicle display screen (such as Figure 3 The Ride-Thru mode card is displayed on the left side of the vehicle display.

[0040] In a possible embodiment, the display information in the vehicle is composed of signals sent by different control units of the vehicle. For example, see Figure 4 , Figure 4 This is a schematic diagram of the vehicle signal transmission module provided in the embodiment of the present application, as shown in FIG. Figure 4 As shown, the integrated control unit (IDCU) includes a microcontroller unit (MCU), a real-time operating system (QNX) and a terminal system (for example, Android); the integrated control unit is connected to the central control unit (CUU) through the CAN bus; the central control unit is connected to the motor drive control unit (MDCU) and the electronic stability control unit (ESC) through the CAN bus. Here, the MDCU sends a vehicle power domain control signal to control the display of highway mode information; the ESC sends a vehicle chassis domain control signal to control the display of crossing mode information.

[0041] In related technologies, if the power domain control signal and / or chassis domain control signal is lost after the vehicle is powered on, the display of the crossing mode, highway mode and the constant display card may be confused, resulting in errors in the displayed information on the vehicle display screen, which in turn causes the driver to be unable to accurately understand the vehicle information, thereby causing vehicle control errors.

[0042] In an embodiment of the present application, during the vehicle power-on process, different display information can be determined in different situations based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal, as well as the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal. The vehicle display screen can be controlled to accurately display vehicle parameter information, providing an accurate reference for the driver's operation, thereby improving the driver's driving accuracy and driving experience.

[0043] In one possible implementation, depending on whether the vehicle is currently in crossing mode, there will be different display processing methods for the information displayed on the vehicle display screen. The following will determine the specific display information of the vehicle display screen from two aspects: when the vehicle is not in crossing mode and when it is in crossing mode.

[0044] First, when the vehicle is not in the crossing mode, find the display on the vehicle display screen that displays the first display information; wherein, the first display information includes: the driving mode information is displayed as blank, the received first signal content information is displayed in the permanent display card, the crossing mode card is displayed according to the received second signal content information, and the permanent display card is displayed.

[0045] In a possible implementation, if it is determined that the current vehicle has not entered the crossing mode and if the chassis domain control signal is not lost, the display information of the vehicle display screen can be determined based on whether the power domain control signal is received.

[0046] Specifically, the step of "when the vehicle is not in the cross-country mode, determining the first display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: a1: When the vehicle is not in the crossing mode, if the chassis domain control signal is not lost, and if the time for which the power domain control signal is not received continuously is greater than a first time threshold, the driving mode information is displayed as blank on the vehicle display screen.

[0047] a2: If it is determined that the vehicle enters the through mode, a through mode card is displayed on the vehicle display screen according to the received second signal content information of the chassis domain control signal.

[0048] In a possible implementation, the chassis domain control signal sent by the ESC includes: ESC_DrivingModeDis = 0x0: Normal or 0x7: Invalid, which indicates that the current vehicle is not in the crossing mode but in the road mode; or the chassis domain control signal is an invalid value; the chassis domain control signal sent by the ESC also includes: ESC_DrivingModeDis = 0x1: Wade (wading mode), 0x2: Sand (sand mode), 0x3: Mud (mud mode), 0x4: Offroad (off-road mode), 0x5: Snow (snow mode), 0x6: Special sand (special sand mode), 0x8: Auto (fully automatic terrain adaptation mode). These signals indicate the specific form of the crossing mode, and the current vehicle mode information is determined through the chassis domain control signal.

[0049] In one possible implementation, if the vehicle is determined not to be in free-ride mode, the chassis domain control signal received from the ESC may be ESC_DrivingModeDis = 0x0: Normal or ESC_DrivingModeDis = 0x7: Invalid. In this case, the specific display content on the vehicle display screen needs to be determined based on the power domain control signal.

[0050] Specifically, if it is determined that the IDCU can receive the chassis domain control signal (IDCU can receive ESC_DrivingModeDis = 0x0:Normal; or ESC_DrivingModeDis = 0x7: Invalid), at this time, it is determined that there is no problem with vehicle communication. If the time for which the power domain control signal is not received continuously is greater than the first time threshold, it is determined that the power domain control signal is lost. At this time, the driving mode information is displayed as empty on the vehicle display screen.

[0051] Here, the first time threshold can be set according to the power domain control signal reception time and the vehicle's information reception response requirements during historical communication. For example, the first time threshold can be set to 500 milliseconds (5 frames).

[0052] Furthermore, because the IDCU can receive chassis domain control signals, if the received chassis domain signal becomes one of ESC_DrivingModeDis=0x1:Wade (wading mode) or 0x2:Sand (sand mode) or 0x3:Mud (mud mode) or 0x4:Offroad (off-road mode), 0x5:Snow (snow mode) or 0x6:Special sand (special sand mode) or 0x8:Auto (fully automatic terrain adaptation mode), it is determined that the current vehicle enters the crossing mode, and then the crossing mode card is displayed on the vehicle display screen according to the content information of the received second signal.

[0053] For example, if the received chassis domain control signal is ESC_DrivingModeDis=0x5:Snow, it indicates that the current vehicle is in snow mode. At this time, the wading mode information is displayed in the crossing mode card displayed on the vehicle display screen, including but not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0054] In another possible implementation, if it is determined that the current vehicle has not entered the crossing mode, if the chassis domain control signal is lost, the display information of the vehicle display screen can be determined based on whether the power domain control signal is received.

[0055] Specifically, the step of "when the vehicle is not in the cross-country mode, determining the first display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: b1: When the vehicle is not in the through mode, if the chassis domain control signal is lost and the power domain control signal is not lost, a constant display card is displayed on the vehicle display screen.

[0056] b2: If the chassis domain control signal is lost, and the power domain control signal is lost or the first signal content information of the power domain control signal is displayed as empty, the driving mode information is displayed as empty on the vehicle display screen.

[0057] In a possible implementation, if it is determined that the current vehicle has not entered the through mode, the judgment condition for the chassis domain control signal being lost may be that the IDCU has not continuously received the chassis domain control signal for a time period greater than a second time threshold.

[0058] Here, similarly, the second time threshold can be set according to the chassis domain control signal reception time and the vehicle's information reception response requirements during historical communication. For example, the second time threshold can be set to 250 milliseconds.

[0059] In one possible implementation, if the IDCU fails to receive the chassis domain control signal continuously for a period greater than a second time threshold, it is determined that the chassis domain signal is lost. At this time, if the IDCU can receive the power domain control signal normally, a permanent display card can be displayed on the vehicle display screen based on the content information of the received first signal, that is, the highway mode card in the permanent display card is displayed according to the specific information content of the power domain control signal.

[0060] In a possible implementation, the power domain control signal sent by the MDCU includes: MDCU_DriverModeResp = 0x2: COMFORT (comfort mode) or 0x3: ECO (standard mode) or 0x4: SPORT (sport mode) or 0x5: 4.9s (sport+ mode).

[0061] For example, if the received power domain control signal is MDCU_DriverModeResp = 0x2: COMFORT, it indicates the current vehicle comfort driving mode. At this time, the comfort mode is displayed in the highway mode of the vehicle's regular display card, and the specific displayed information includes but is not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0062] In one possible implementation, the normally displayed card includes multiple display cards. When it is determined that the power domain control signal is received, the highway mode card will not be actively displayed. However, if a switching instruction is received from the driver, the display of the highway mode card can be switched on the vehicle display screen.

[0063] Specifically, the display method further includes: c1: In response to a switch operation on the normally displayed card, a highway mode card is displayed.

[0064] In one possible embodiment, the switching operation for the normally displayed card can be issued by the driver pressing the control button on the steering wheel. Through the driver's control operation on the steering wheel, the card switching direction is controlled to switch to the display of the highway mode card.

[0065] For example, the constantly displayed card is displayed below the vehicle display screen. From left to right, the displayed content includes energy consumption information, multimedia information, navigation information, tire pressure information, driving mode information (highway mode), speed and water temperature information. At this time, if it is the tire pressure information display interface, you can switch to the display of the highway mode card by pressing the right direction key.

[0066] In another possible implementation, if it is determined that the current vehicle has not entered the crossing mode, if the received power domain control signal is an empty signal, the driving information displayed on the vehicle display screen is empty, and after it is determined that the vehicle has entered the crossing mode, it is displayed according to the chassis domain control signal.

[0067] Specifically, the step of "when the vehicle is not in the cross-country mode, determining the first display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: d1: When the vehicle is not in the crossing mode, if the first signal content information of the power domain control signal is displayed as blank, the driving mode information is displayed as blank on the vehicle display screen.

[0068] d2: If it is determined that the vehicle enters the through mode, a through mode card is displayed on the vehicle display screen according to the received second signal content information of the chassis domain control signal.

[0069] In one possible implementation, if it is determined that the vehicle is not currently in the crossing mode and the IDCU can normally receive the power domain control signal, the power domain control signal is interpreted and the power domain control signal is MDCU_DriverModeResp = 0x1: None. It is determined that the power domain control signal is empty at this time, and the driving mode information is displayed as empty on the vehicle display screen.

[0070] Furthermore, similarly, at this time, if the received chassis domain signal changes to one of ESC_DrivingModeDis=0x1:Wade (wading mode) or 0x2:Sand (sand mode) or 0x3:Mud (mud mode) or 0x4:Offroad (off-road mode), 0x5:Snow (snow mode) or 0x6:Special sand (special sand mode) or 0x8:Auto (fully automatic terrain adaptation mode), it is determined that the current vehicle enters the crossing mode, and then the crossing mode card is displayed on the vehicle display screen according to the content information of the received second signal.

[0071] For example, if the received chassis domain control signal is ESC_DrivingModeDis=0x1:Wade, it indicates that the current vehicle is in wading mode. At this time, the wading mode information is displayed in the crossing mode card displayed on the vehicle display screen, including but not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0072] In another possible implementation, if it is determined that the current vehicle has not entered the crossing mode, if the power domain control signal can be received normally, and the first signal content of the power domain control signal is not empty, then the display is performed normally according to the first signal content.

[0073] Specifically, the step of "when the vehicle is not in the cross-country mode, determining the first display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: e1: When the vehicle is not in the crossing mode, the received first signal content information of the power domain control signal is displayed in a permanent display card on the vehicle display screen.

[0074] In an embodiment of the present application, when the vehicle is not in the crossing mode, if the IDCU can normally receive the power domain control signal and the first signal content information of the power domain control signal is not displayed as empty, at this time, a permanent display card can be displayed on the vehicle display screen according to the received first signal content information, that is, the highway mode card in the permanent display card is displayed according to the specific information content of the power domain control signal.

[0075] For example, if the received power domain control signal is MDCU_DriverModeResp = 0x3: ECO, it represents the current vehicle standard driving mode. At this time, the comfort mode is displayed in the highway mode of the vehicle's regular display card, and the specific displayed information includes but is not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0076] In a possible implementation, similarly, multiple display cards are included in the normally displayed card. When it is determined that the power domain control signal is received, the highway mode card will not be actively displayed. However, if a switching instruction is received from the driver, the display of the highway mode card can be switched to the display of the highway mode card on the vehicle display screen. The specific switching display process is the same as the above and will not be repeated here.

[0077] Secondly, when the vehicle is in the crossing mode, find the one displaying the second display information on the vehicle display screen; the second display information includes: displaying the crossing mode card according to the received second signal content information, and displaying the crossing mode card according to the historical signal content information of the last chassis domain control signal received.

[0078] S102. When the vehicle is in the crossing mode, the second display information of the vehicle display screen is determined based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal.

[0079] In one possible implementation, after it is determined that the vehicle enters the crossing mode, if it is determined that the chassis domain control signal currently received by the IDCU is switched to invalid, the display information of the vehicle display screen is determined based on the first signal content information of the received power domain control signal.

[0080] Specifically, the step of "when the vehicle is in the crossing mode, determining the second display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: f1: When the vehicle is in the crossing mode, if the information of the chassis domain control signal is invalid, the received first signal content information of the power domain control signal is displayed in the constant display card of the vehicle display screen according to the received first signal content information of the power domain control signal.

[0081] In one possible implementation, the chassis domain control signal may be invalid when the received signal is ESC_DrivingModeDis = 0x7: Invalid, which determines that the vehicle has currently exited the driving mode. At this time, if the IDCU can normally receive the power domain control signal, it will be displayed according to the first signal content information contained in the power domain control signal.

[0082] At this time, similarly, a permanent display card can be displayed on the vehicle display screen according to the received first signal content information, that is, the highway mode card in the permanent display card is displayed according to the specific information content of the power domain control signal.

[0083] For the above example, if the received power domain control signal is MDCU_DriverModeResp = 0x4: SPORT, it represents the current vehicle sports driving mode. At this time, the vehicle's normal display card displays the operating mode at the road mode. The specific displayed information includes but is not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0084] In one possible implementation, the constant display card includes multiple display cards. When a power domain control signal is received, the highway mode card is not automatically displayed. However, upon receiving a driver-initiated switch command, the vehicle display can switch to the highway mode card. The specific switching process is the same as described above and will not be further described here.

[0085] Furthermore, if it is determined that the chassis domain control signal received by the IDCU has returned to normal, it is determined that the vehicle has entered the crossing mode again. At this time, according to the second signal content information of the chassis domain control signal, the crossing mode card is displayed on the vehicle display screen according to the received second signal content information.

[0086] Specifically, if the chassis domain signal received at this time becomes one of ESC_DrivingModeDis=0x1:Wade (wading mode) or 0x2:Sand (sand mode) or 0x3:Mud (mud mode) or 0x4:Offroad (off-road mode), 0x5:Snow (snow mode) or 0x6:Special sand (special sand mode) or 0x8:Auto (fully automatic terrain adaptation mode), it is determined that the chassis domain control signal received by the IDCU has returned to normal, and then the crossing mode card is displayed on the vehicle display screen according to the content information of the received second signal.

[0087] For example, if the received chassis domain control signal is ESC_DrivingModeDis=0x3:Mud, it indicates that the current vehicle is in mud mode. At this time, the mud mode information is displayed in the crossing mode card displayed on the vehicle display screen, including but not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0088] In another possible implementation, after it is determined that the vehicle has entered the through mode, if the time for which no chassis domain control signal is continuously received is greater than a second time threshold, the current display of the through mode card is maintained.

[0089] Specifically, the step of "when the vehicle is in the crossing mode, determining the second display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: g1: When the vehicle is in the through mode, if the time for which the chassis domain control signal is not received continuously is greater than a second time threshold, a through mode card is displayed on the vehicle display screen based on the historical signal content information of the last chassis domain control signal received.

[0090] In one possible implementation, if the time for which the chassis domain control signal is not received continuously is greater than a second time threshold, it is determined that the chassis domain control signal is lost. At this time, the IDCU displays a through mode card based on the historical signal content information of the previous chassis domain control signal.

[0091] Here, similarly, the second time threshold can be set according to the chassis domain control signal reception time and the vehicle's information reception response requirements during historical communication. For example, the second time threshold can be set to 250 milliseconds.

[0092] For example, if the last chassis domain control signal received is ESC_DrivingModeDis=0x2:Sand, and if the current chassis domain control signal is lost, the sand mode information will continue to be displayed in the crossing mode card displayed on the vehicle display screen, including but not limited to: vehicle pitch angle information, vehicle roll angle information, altitude information and direction information.

[0093] In another possible implementation, after it is determined that the vehicle enters the through mode, if the time for which the power domain control signal is not received continuously is greater than a first time threshold and the chassis domain control signal is lost, the current display of the through mode card is maintained.

[0094] Specifically, the step of "when the vehicle is in the crossing mode, determining the second display information of the vehicle display screen based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal" includes: h1: When the vehicle is in the through mode, if the time for which the power domain control signal is not received continuously is greater than the first time threshold and the chassis domain control signal is not lost, a through mode card is displayed on the vehicle display screen according to the content information of the received second signal.

[0095] h2: When the vehicle is in the through mode, if the time for which the power domain control signal has not been received continuously is greater than the first time threshold and the chassis domain control signal is lost, the through mode card is displayed based on the historical signal content information of the last chassis domain control signal received, and the signal loss information is displayed.

[0096] In one possible implementation, after the vehicle enters the crossing mode, if the time for which the power domain control signal is not received continuously is greater than a first time threshold, it is determined that the power domain control signal is lost. At this time, if the chassis domain control signal is not lost, a crossing mode card is displayed on the vehicle display screen based on the content information of the received second signal.

[0097] In another possible embodiment, after the vehicle enters the through mode, if the time for which the power domain control signal is not received continuously is greater than a first time threshold (for example, 500 milliseconds), and the chassis domain control signal is also lost, the through mode card is first displayed based on the historical signal content information of the last chassis domain control signal received, and the signal loss information is displayed at the same time, prompting the driver to check whether there is any interruption in the communication between the current IDCU and the ESC and MDCU, so as to ensure that the driver can accurately and timely receive the vehicle's driving parameters.

[0098] Furthermore, when the vehicle is powered off, the user directly enters the cross-country mode from the normal display card and then powers off directly. At this time, the ESC does not feedback the exit cross-country mode signal (that is, exiting the cross-country mode, the normal feedback should be: road mode). That is, during the power-off process, the MDCU driving mode and the ESC cross-country mode will exist at the same time. When the vehicle is powered on again, because the instrument IDCU is in a fast start state, that is, the QNX system powers on faster than the MDCU&ESC, the actual MDCU&ESC signal has not yet been fed back. At this time, the IDCU measure is to memorize the MDCU&ESC signal status at the time of power off. Therefore, there is sometimes a problem of displaying the cross-country or road mode card, and the normal display card required for normal requirements is not displayed. The normal display card status before entering the cross-country mode is not restored, and there is a display error. Therefore, when the vehicle is powered off, it is possible to check whether it is currently in the cross-country mode, and after confirming that the vehicle is in the cross-country mode when powered off, clear the cross-country mode. Then, after the vehicle is powered on again, the normal display card is displayed normally to ensure the accuracy of the vehicle display.

[0099] Specifically, the display method further includes: i1: When the vehicle's power mode is switched to power-off mode, detect whether the vehicle is in cross-country mode.

[0100] i2: If the current vehicle is in the through mode, clear the display content corresponding to the through mode and save the normal display content before switching to the through mode.

[0101] i3: When the vehicle power mode is switched to the power-on mode, a permanent display card is displayed on the vehicle display screen according to the permanent display content.

[0102] In the embodiment of the present application, if it is determined that the vehicle power supply is switched from the local on state (local on), the ready state (ready), and the remote wake-up state (remote on) to the off state (off), it is determined that the vehicle is switched to the power-off mode.

[0103] In one possible implementation, when the vehicle's power mode is switched to the power-off mode, if it is determined that the vehicle is not currently in the crossing mode, there is no need to clear the data. When the vehicle's power mode is switched to the power-on mode, the permanent display card is displayed on the vehicle display screen according to the permanent display content.

[0104] In another possible implementation, when the vehicle's power mode is switched to power-off mode, if it is determined that it is currently in through mode, the IDCU needs to actively clear the through mode card status and return the through mode card page to the normal display card before entering the through mode. When the vehicle's power mode is switched to power-on mode, the normal display card is displayed on the vehicle display screen according to the normal display content.

[0105] The following is an example of how the vehicle driving mode display process in the embodiment of the present application is described: For example, see Figure 5 , Figure 5 The display flow chart of the vehicle driving mode when the vehicle provided in this application is not in the crossing mode, such as Figure 5 As shown, the vehicle is powered on and receives CAN signals from ESC (chassis domain control signal) and MDCU (power domain control signal). Based on the received CAN signals, it is determined that the vehicle is not currently in the crossing mode; if the power domain control signal is empty and the chassis domain control signal is road mode or an invalid value, the driving mode information is displayed as empty; if the power domain control signal is lost or the power domain control signal is empty and the chassis domain control signal is not road mode or an invalid value, the crossing mode card and crossing mode information are displayed; if the chassis domain control signal is lost and the power domain control signal is not lost and the power domain control signal is not empty; or if the chassis domain control signal is an invalid value and the power domain control signal is not lost and the power domain control signal is not empty, the driving mode information displays Comfort, Standard, Sport, and Sport+; if the power domain control signal is empty and the chassis domain control signal is lost or the chassis domain control signal is an invalid value, the driver switches the road mode card through a switching operation, and the driving mode information is displayed as empty.

[0106] For example, see Figure 6 , Figure 6 The display flow chart of the vehicle driving mode when the vehicle provided by this application is in the crossing mode, such as Figure 6 As shown, the vehicle is powered on and receives CAN signals from ESC (chassis domain control signal) and MDCU (power domain control signal). Based on the received CAN signals, it is determined that the vehicle currently enters the crossing mode. If the chassis domain control signal is lost or the power domain control signal is lost, the crossing mode card and crossing mode information are displayed; if the chassis domain control signal is invalid and the power domain control signal is not lost and the power domain control signal is not empty, the driving mode information displays Comfort, Standard, Sport, and Sport+; if the chassis domain control signal is wading mode, sand mode, mud mode, off-road mode, snow mode, special sand mode, or fully automatic terrain adaptation mode, the crossing mode card and crossing mode information are displayed.

[0107] The method for displaying a vehicle driving mode provided in an embodiment of the present application determines, during the vehicle power-on process, when the vehicle is not in the crossing mode, the first display information of the vehicle display screen is determined based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal; wherein the first display information includes: the driving mode information is displayed as blank, the received first signal content information is displayed in the permanent display card, the crossing mode card is displayed according to the received second signal content information, and the permanent display card is displayed; during the vehicle power-on process, when the vehicle is in the crossing mode, the second display information of the vehicle display screen is determined based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal and the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal; wherein the second display information includes: the crossing mode card is displayed according to the received second signal content information, and the crossing mode card is displayed according to the historical signal content information of the last chassis domain control signal received. In this way, during the vehicle power-on process, different display information can be determined in different situations based on the signal loss status of the vehicle's power domain control signal and the chassis domain control signal, as well as the first signal content information of the power domain control signal and / or the second signal content information of the chassis domain control signal. The vehicle display screen can be controlled to accurately display vehicle parameter information, providing accurate reference for the driver's operation, thereby improving the driver's driving accuracy and driving experience.

[0108] Furthermore, when the vehicle is powered off, it is checked whether it is currently in the through mode, and after determining that the vehicle is in the through mode when it is powered off, the through mode is cleared, and then after the vehicle is powered on again, the normally displayed card is displayed normally to ensure the accuracy of the vehicle display.

[0109] Based on the same inventive concept, an embodiment of the present application also provides a display device for a vehicle driving mode corresponding to the display of the vehicle driving mode. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the above-mentioned method for displaying the vehicle driving mode in the embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
