[0002] With the continuous development of intelligent technologies, more and more car manufacturers are applying these technologies to automobiles. As a crucial component of automotive intelligence, the central control screen's touch soft switch is naturally receiving increasing attention and importance. Virtual switches are an essential part of a vehicle's electronic system, controlling various functions and systems such as braking, steering, and lighting. Compared to traditional physical buttons, touch soft switches can make the interior look more streamlined, stylish, and upscale, enhancing the overall aesthetics and aligning with modern aesthetic preferences. Furthermore, touch soft switches don't require additional space like physical buttons, saving interior space and simplifying maintenance as they don't require disassembly or replacement. In addition, the software for the central control screen's touch soft switch can be upgraded at any time, allowing car manufacturers to update vehicle functions and operating methods without hardware changes, significantly improving maintainability.

[0039] Example 1

[0040] Figure 1This is a flowchart illustrating a method for detecting the failure of a vehicle touch soft switch according to Embodiment 1 of the present invention. This method is applicable to situations where the effectiveness of a touch soft switch on a vehicle's central control display screen is detected. This method can be executed by a vehicle touch soft switch failure detection device, which can be implemented by software and / or hardware and is generally integrated into the central control device. In this embodiment, the central control device includes, but is not limited to, the vehicle's central control device.

[0041] like Figure 1 As shown, the vehicle touch soft switch failure detection method provided in Embodiment 1 of the present invention includes the following steps:

[0042] S110. A fixed area is set on the infotainment display screen of the vehicle's touch soft switch system.

[0043] It should be noted that, Figure 2 This is a schematic diagram of a vehicle touch soft switch system provided in Embodiment 1 of the present invention, as shown below. Figure 2 As shown, the vehicle touch soft switch system consists of an infotainment display screen, an infotainment controller, and a signal bus. The infotainment controller includes a screen rendering module and a touch detection module. The screen rendering module depicts the display screen according to the human-machine interface design and transmits the screen information to the microcontroller unit of the infotainment display screen for display driving, so that the infotainment display screen displays the corresponding screen. The infotainment display screen also detects the user's touch state and touch position on the screen and feeds the touch position and touch state back to the touch detection module of the infotainment controller for judgment. The touch detection module of the infotainment controller determines which soft switch the user has touched based on the touch position and touch state, and transmits the corresponding instruction of the soft switch to the corresponding electronic control unit (ECU) through the signal bus to execute the corresponding function.

[0044] For example, the screen rendering module in the infotainment controller performs virtual rendering of the low beam switch and sends the screen information to the display driver of the infotainment display to display the virtual low beam switch button. When the detection module in the infotainment display detects that the user touches the infotainment display, it feeds back the touch state and touch position to the touch determination module in the infotainment controller. The touch determination module determines that the user has clicked the low beam soft switch on button based on the touch state and touch position, and then sends the command to turn on the low beam to the corresponding ECU through the signal bus to execute the operation of turning on the low beam.

[0045] In this embodiment, an area can be set on the infotainment display screen of the vehicle touch soft switch system. Preferably, the fixed area can be set in an invisible area on the infotainment display screen, so that the fixed area will not block the screen and avoid affecting the normal display of the infotainment display screen.

[0046] This embodiment does not impose specific restrictions on the setting method of the fixed area, nor does it elaborate on the specific setting process.

[0047] S120. Determine the display status of the fixed area.

[0048] In this embodiment, the display status of the fixed area can be determined in a variety of ways to determine whether the fixed area can be displayed normally according to the instructions.

[0049] One feasible approach is to define two icons and send their display information to the infotainment display screen. This allows the two icons to be displayed alternately within a fixed area on the infotainment display screen. If the alternating display of the two icons within the fixed area is detected, then the display status of the fixed area is considered normal. It is understood that the area of ​​the fixed area is larger than the area of ​​either of the two icons, allowing both icons to be displayed completely within the fixed area.

[0050] S130. Determine whether the infotainment display screen is frozen based on the display status of the fixed area.

[0051] In this embodiment, whether the infotainment display screen has frozen can be determined based on whether the display status of a fixed area is normal. Frozen screen can be understood as the screen becoming unresponsive, as if it is stuck.

[0052] Specifically, determining whether the infotainment display screen has frozen based on the display status of the fixed area includes:

[0053] If the fixed area displays normally, then it is determined that the infotainment display screen has not frozen.

[0054] If the display status of the fixed area is abnormal, it is determined that the infotainment display screen has frozen.

[0055] If the first icon and the second icon are displayed alternately in the fixed area according to the corresponding instructions, it can be determined that the infotainment display screen has not frozen; if the first icon and the second icon are not displayed alternately in the fixed area according to the corresponding instructions, it can be determined that the infotainment display screen has frozen.

[0056] S140. If the infotainment display screen freezes, it is determined that the soft switch of the car touch screen displayed on the infotainment display screen has failed.

[0057] Among them, the automotive touch screen soft switch can be understood as a virtual switch. The automotive touch screen soft switch is displayed on the infotainment display screen and can include soft switches with various functions, such as high beam switch, turn signal switch and air conditioning switch.

[0058] In this embodiment, the failure of the car touchscreen soft switch is determined by whether the infotainment display screen freezes. It is understood that since the car touchscreen soft switch is displayed on the infotainment display screen, if the infotainment display screen freezes, the car touchscreen soft switch will also fail to respond normally. This is similar to a computer crashing, where clicking an icon on a computer screen with a mouse results in no response.

[0059] This invention provides a method for detecting the failure of a vehicle touch soft switch. First, a fixed area is set on the infotainment display screen of the vehicle touch soft switch system. Then, the display state of the fixed area is determined. Next, based on the display state of the fixed area, it is determined whether the infotainment display screen has frozen. Finally, if the infotainment display screen has frozen, it is determined that the vehicle touch screen soft switch displayed on the infotainment display screen has failed. The above method can detect whether a frozen screen has occurred based on the display state of the fixed area, and thus determine whether the vehicle touch screen soft switch has failed.

[0060] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0061] In one embodiment, determining the display state of the fixed area includes:

[0062] The infotainment controller in the vehicle's touch soft switch system alternately displays a first icon and a second icon in a fixed area. The first icon and the second icon are two distinguishable icons of the same size.

[0063] The detection module in the infotainment display screen detects whether the first icon and the second icon are displayed alternately in the fixed area according to the corresponding instructions.

[0064] If the first icon and the second icon are displayed alternately in the fixed area according to the corresponding instructions, then the display status of the fixed area is determined to be normal.

[0065] The detection module in the infotainment display can detect whether the first icon and the second icon are alternately displayed in a fixed area according to the corresponding instructions. For example, the instruction is that the first icon is displayed in a fixed area for 2 seconds and then the second icon is displayed in a fixed area for 3 seconds. If the first icon and the second icon are detected to alternately displayed according to the time specified by the instruction, it is determined that the first icon and the second icon are alternately displayed according to the corresponding instruction. If the first icon and the second icon are detected to alternately displayed according to the time specified by the instruction, it is determined that the first icon and the second icon are not alternately displayed according to the corresponding instruction. For example, if the first icon is detected to be displayed continuously in a fixed area but the second icon is not displayed, or if the first icon is detected to be displayed in a fixed area for 1 second and the second icon is detected to be displayed in a fixed area for 5 seconds, it is determined that the first icon and the second icon are not alternately displayed according to the corresponding instruction.

[0066] Furthermore, the infotainment controller in the vehicle touch soft switch system alternately displays a first icon and a second icon in the fixed area, including:

[0067] The infotainment controller in the vehicle's touch soft switch system alternately displays the first and second icons;

[0068] The infotainment controller sends the display information of the first icon and the display information of the second icon to the infotainment display screen, so that the first icon and the second icon are displayed alternately in the fixed area.

[0069] In one embodiment, the touch soft switch is provided with a secondary confirmation function, which includes displaying a pop-up window when the touch soft switch is detected to allow the user to confirm whether the touch soft switch has been clicked.

[0070] To prevent malfunctions in a single location on the infotainment display, a secondary confirmation function can be implemented. A pop-up window can be displayed in an area of ​​the infotainment display other than the location of the touch soft switch. Since the area where the pop-up window is located is not malfunctioning, the user can click the confirmation button on the pop-up window normally. For example, if a single malfunction occurs at the location of the low beam headlight touch soft switch, a pop-up window can be displayed in another location, and the user can turn on the low beam headlights normally after clicking the confirmation button on the pop-up window.

[0071] One way to prevent users from accidentally touching the soft switch is to set up a secondary confirmation function. For example, if a user accidentally touches the soft switch to turn on the low beam headlights, a pop-up window will be displayed to ask the user to confirm whether to turn on the low beam headlights, so as to ensure that the user's command is executed correctly.

[0072] Example 2

[0073] Figure 3This is a flowchart illustrating a method for detecting the failure of a vehicle touch soft switch according to Embodiment 2 of the present invention. Embodiment 2 is an optimization based on the above embodiments. For details not covered in this embodiment, please refer to Embodiment 1.

[0074] like Figure 3 As shown, the second embodiment of the present invention provides a method for detecting the failure of a vehicle touch soft switch, which includes the following steps:

[0075] S210. A fixed area is set on the infotainment display screen of the vehicle's touch soft switch system.

[0076] S220. Determine the display status of the fixed area.

[0077] S230. Determine whether the infotainment display screen is frozen based on the display status of the fixed area.

[0078] S240. If the infotainment display screen freezes, it is determined that the soft switch of the car touch screen displayed on the infotainment display screen has failed.

[0079] S250. If it is determined that the infotainment display screen is frozen, the default command sent by the infotainment controller in the vehicle touch soft switch system is transmitted to the corresponding electronic control unit via the signal bus to control the vehicle touch screen soft switch to the corresponding safe state.

[0080] In this embodiment, if it is determined that the infotainment display screen is frozen, the infotainment controller in the vehicle touch soft switch system can send a default command to the corresponding electronic control unit via the signal bus, so that the corresponding electronic control unit can execute the default command.

[0081] Different touch soft switches correspond to different default commands. For example, the default command for the low beam headlight touch soft switch is to turn off the low beam headlights. For instance, if a frozen infotainment display is detected, the infotainment controller in the vehicle's touch soft switch system can send a command to turn off the low beam headlights to the low beam headlight electronic control unit via the signal bus, and the low beam headlight electronic control unit can then turn off the low beam headlights.

[0082] Embodiment 2 of this invention provides a method for detecting the failure of a vehicle touchscreen soft switch. This method specifies the process of determining the display state of a fixed area. By setting two different icons and determining whether the two icons can be displayed alternately, the method can accurately judge the display state of the fixed area, thereby effectively determining whether the vehicle touchscreen soft switch has failed. Furthermore, when the method detects a frozen infotainment display screen, it can execute a default command to put the vehicle touchscreen soft switch into a safe state, reducing the risk of damage to the entire vehicle.

[0083] Based on the technical solutions of the above embodiments, this invention provides several specific implementation methods.

[0084] As one specific implementation method of this embodiment. Figure 4 A schematic flowchart of a vehicle touch soft switch failure detection method provided in a specific embodiment of the present invention is shown below. Figure 4 As shown, the process includes the following steps: two identical and distinguishable icons, A and B, are alternately displayed at fixed positions on the touch screen; the screen rendering module alternately renders icons A and B at the fixed positions and transmits the display information to the touch screen; the screen freeze detection module periodically obtains the CRC value of the display driver to determine whether the touch screen has sent a screen freeze signal; if a screen freeze occurs, the touch determination module of the infotainment controller is notified; the touch determination module sets the safety soft switch to the corresponding safety state; and the infotainment controller sends the touch soft switch status command to the communication bus.

[0085] In another specific embodiment, the touch soft switch adds a secondary confirmation operation, displaying pop-ups at different locations on the screen to prevent the inability to activate the corresponding function due to a malfunction in a single location of the screen.

[0086] Example 3

[0087] Figure 5 This is a schematic diagram of a vehicle touch soft switch failure detection device provided in Embodiment 3 of the present invention. The device is applicable to the situation of detecting the effectiveness of touch soft switches on the central control display screen of a vehicle.

[0092] The third determining module 140 is used to determine that the soft switch of the car touch screen displayed on the infotainment display screen is malfunctioning if the infotainment display screen freezes.

[0093] In this embodiment, the device first sets a fixed area on the infotainment display screen of the vehicle touch soft switch system through the setting module 110; then, the first determining module 120 determines the display state of the fixed area; then, the second determining module 130 determines whether the infotainment display screen is frozen based on the display state of the fixed area; finally, the third determining module 140 determines that the car touch screen soft switch displayed on the infotainment display screen is malfunctioning if the infotainment display screen is frozen.

[0094] This embodiment provides a vehicle touch soft switch failure detection device, which can determine whether the soft switch of a car touch screen is effective.

[0095] Furthermore, the first determining module 120 includes:

[0096] The display unit is used to alternately display a first icon and a second icon in the fixed area, wherein the first icon and the second icon are two distinguishable icons of the same size;

[0097] The detection unit is used to detect whether the first icon and the second icon are displayed alternately according to the corresponding instructions within the fixed area;

[0098] The determining unit is configured to determine that the display status of the fixed area is normal if the first icon and the second icon are alternately displayed in the fixed area according to the corresponding instructions.

[0099] Based on the above optimizations, the display unit is specifically used to: alternately depict a first icon and a second icon; and send the display information of the first icon and the display information of the second icon to the infotainment display screen, so that the first icon and the second icon are alternately displayed in the fixed area.

[0100] Furthermore, the second determining module 130 is specifically used to: if the display status of the fixed area is normal, then determine that the infotainment display screen has not frozen; if the display status of the fixed area is abnormal, then determine that the infotainment display screen has frozen.

[0101] Furthermore, the device also includes a control module, which, if it is determined that the infotainment display screen has frozen, transmits the default command sent by the infotainment controller in the vehicle touch soft switch system to the corresponding electronic control unit via a signal bus, so as to control the vehicle touch screen soft switch to the corresponding safe state.

[0102] Furthermore, the touch soft switch is equipped with a secondary confirmation function, which includes displaying a pop-up window when the touch soft switch is detected to allow the user to confirm whether the touch soft switch has been clicked.
