Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle four-wheel drive switch display technology, and in particular to a display control method, device, vehicle, and storage medium for an intelligent four-wheel drive switch. Background Art

[0002] With the development of vehicle drive technology, vehicle configurations are constantly changing, and the transfer cases of four-wheel drive models are gradually updated from part-time four-wheel drive systems to intelligent four-wheel drive systems.

[0003] The four-wheel drive mode of the intelligent four-wheel drive system adds an intelligent four-wheel drive (Auto Wheel Drive, AWD) mode on the basis of the four-wheel drive mode of the part-time four-wheel drive system. In the AWD mode, the motor position of the transfer case is the same as the motor position of the two-wheel drive mode (2-Wheel Drive, 2WD). The strategy of the part-time four-wheel drive system in related technologies to determine the four-wheel drive mode according to the motor position and to display the switch is not applicable to the intelligent four-wheel drive system.

[0004] Therefore, there is an urgent need for a switch display strategy suitable for intelligent four-wheel drive systems. Summary of the Invention

[0005] The present disclosure provides a display control method, device, vehicle and storage medium for an intelligent four-wheel drive switch to solve the problem in the related art that the four-wheel drive mode is determined according to the motor position and the switch display cannot accurately distinguish between the 2WD mode and the AWD mode.

[0006] In a first aspect, an embodiment of the present disclosure provides a display control method for an intelligent four-wheel drive switch, comprising: Obtaining a first four-wheel drive state signal value, wherein the first four-wheel drive state signal value is the four-wheel drive state signal value when the vehicle is last powered off; matching the first four-wheel drive state signal value with a four-wheel drive state signal value corresponding to a target four-wheel drive mode; outputting first indication information when the first four-wheel drive state signal value successfully matches the four-wheel drive state signal value corresponding to the first four-wheel drive mode, wherein the first four-wheel drive mode is one of the target four-wheel drive modes; The first indication information is used to indicate that the current four-wheel drive mode is the first four-wheel drive mode.

[0007] Optionally, the method further comprises: When the first four-wheel drive state signal value fails to match the four-wheel drive state signal value corresponding to the target four-wheel drive mode, obtaining a preset switch state signal value; The preset switch state signal value is sent to the four-wheel drive controller, and second indication information is output, where the second indication information is used to indicate that the second four-wheel drive mode corresponding to the preset switch state signal value is currently in the startup process.

[0008] In this embodiment, when the first four-wheel drive state signal value fails to match the four-wheel drive state signal value corresponding to the target four-wheel drive mode, a preset switch state signal value is sent to the four-wheel drive controller, and an indication message is output to indicate that the second four-wheel drive mode corresponding to the preset switch state signal value is currently in the startup process. This can remind the user of the four-wheel drive mode currently being started, making it convenient for the user to intuitively know which four-wheel drive mode is being started, thereby improving the user experience.

[0009] Optionally, the method further includes: Acquire a second four-wheel drive state signal value, where the second four-wheel drive state signal value is a response made by the four-wheel drive controller after receiving the preset switch state signal value; When the third four-wheel drive mode corresponding to the second four-wheel drive state signal value is the same as the second four-wheel drive mode, third indication information is output, where the third indication information is used to indicate that the current four-wheel drive mode is the second four-wheel drive mode.

[0010] In this embodiment, after the four-wheel drive controller receives the preset switch status signal value, it starts the corresponding four-wheel drive mode and returns the corresponding second four-wheel drive status signal value to the intelligent four-wheel drive switch. If the intelligent four-wheel drive switch determines that the third four-wheel drive mode corresponding to the second four-wheel drive status signal value is the same as the second four-wheel drive mode, it outputs an indication message indicating that the current four-wheel drive mode is the second four-wheel drive mode. This provides convenience for the user to intuitively know the four-wheel drive mode that has been successfully started. In addition, different indication messages are output during the four-wheel drive mode startup process and after successful startup, which enables the user to intuitively know the startup process of the four-wheel drive mode and improve the user experience.

[0011] Optionally, the method further includes: In response to receiving a user switching operation for a fourth four-wheel drive mode, obtaining a second switch state signal value corresponding to the fourth four-wheel drive mode; The second switch state signal value is sent to the four-wheel drive controller, and fourth indication information is output, where the fourth indication information is used to indicate that the fourth four-wheel drive mode is currently being switched.

[0012] In this embodiment, when the user switches the four-wheel drive mode to the fourth four-wheel drive mode, the intelligent four-wheel drive switch sends the second switch state signal value corresponding to the fourth four-wheel drive mode to the four-wheel drive controller, and outputs the fourth indication information for indicating that the vehicle is currently in the switching process of the fourth four-wheel drive mode. It can output the current four-wheel drive mode state, making it convenient for the user to obtain information that the vehicle is currently in the switching process of the fourth four-wheel drive mode, thereby improving the user experience.

[0013] Optionally, the method further includes: Get the third four-wheel drive status signal value; After the display time of the fourth indication information reaches a preset time, determining whether the fifth four-wheel drive mode corresponding to the third four-wheel drive state signal value is the same as the fourth four-wheel drive mode; When the fifth four-wheel drive mode is the same as the fourth four-wheel drive mode, fifth indication information is output, where the fifth indication information is used to indicate that the current four-wheel drive mode is the fourth four-wheel drive mode.

[0014] In this embodiment, after the intelligent four-wheel drive switch receives the third four-wheel drive status signal value sent by the four-wheel drive controller and the display time of the fourth indication information reaches a preset time, it determines whether the fifth four-wheel drive mode corresponding to the third four-wheel drive status signal value is the same as the fourth four-wheel drive mode. By waiting for the preset time and then executing the judgment logic, sufficient time is reserved for the four-wheel drive controller to switch the four-wheel drive mode, which can ensure that the four-wheel drive controller has completed the four-wheel drive mode switching operation and returned the corresponding four-wheel drive status signal value at this time, and can also avoid unnecessary judgment operations when the user continuously switches the four-wheel drive mode; after determining that the fifth four-wheel drive mode is the same as the fourth four-wheel drive mode, the intelligent four-wheel drive switch outputs the fifth indication message for indicating that the current four-wheel drive mode is in the fourth four-wheel drive mode, which provides convenience for the user to know the current four-wheel drive mode; and different indication messages are output during the four-wheel drive mode switching process and after the successful switching, so that the user can intuitively know the four-wheel drive mode switching process and improve the user experience.

[0015] Optionally, the method further includes: Before the display duration of the fourth indication information reaches the preset duration, in response to receiving a switching operation of the user to the sixth four-wheel drive mode, obtaining a third switch state signal value corresponding to the sixth four-wheel drive mode; Outputting sixth indication information and restarting the timing, wherein the sixth indication information is used to indicate that the vehicle is currently in the process of switching to the sixth four-wheel drive mode; The third switch state signal value is sent to the four-wheel drive controller.

[0016] In this embodiment, if the user performs a switching operation to the sixth four-wheel drive mode before the display duration of the fourth indication information reaches the preset duration, indication information for indicating that the user is currently in the switching process of the sixth four-wheel drive mode is output to ensure that the output indication information matches the four-wheel drive mode switched by the user, and the timing is restarted after the indication information is output, so as to match the four-wheel drive mode after the display duration of the restarted indication information reaches the preset duration, thereby ensuring that the display duration of the indication information related to the new switching mode can also reach the preset duration, thereby reserving sufficient time for the four-wheel drive controller to switch the four-wheel drive mode, and ensuring that the intelligent four-wheel drive switch can receive the four-wheel drive status signal value responded by the four-wheel drive controller within the preset duration.

[0017] Optionally, the target four-wheel drive mode includes a two-wheel drive mode, a four-wheel drive high-speed mode, an intelligent four-wheel drive mode and a four-wheel drive low-speed mode.

[0018] In this embodiment, the target four-wheel drive mode includes a two-wheel drive mode, a four-wheel drive high-speed mode, an intelligent four-wheel drive mode and a four-wheel drive low-speed mode. The intelligent four-wheel drive switch matches the four-wheel drive status signal value saved when the vehicle was powered off last time with the four-wheel drive status signal value corresponding to the target four-wheel drive mode. If a match is found, an indication message is output indicating that the current four-wheel drive mode is the four-wheel drive mode corresponding to the four-wheel drive status signal value that has been successfully matched. For example, an indicator light corresponding to the four-wheel drive mode is turned on to facilitate the user to know the current four-wheel drive mode. This enables the vehicle to be powered on again after being powered on in any four-wheel drive mode. The four-wheel drive mode displayed by the intelligent four-wheel drive switch can be consistent with the four-wheel drive mode displayed before the last power-off, thereby achieving the effect of the intelligent four-wheel drive switch memorizing the four-wheel drive mode.

[0019] In a second aspect, an embodiment of the present disclosure provides a display control device for an intelligent four-wheel drive switch, comprising: A four-wheel drive signal acquisition module is used to obtain a first four-wheel drive state signal value, wherein the first four-wheel drive state signal value is the four-wheel drive state signal value when the vehicle is last powered off; a matching module, configured to match the first four-wheel drive state signal value with a four-wheel drive state signal value corresponding to a target four-wheel drive mode; a control module, configured to output first indication information when the first four-wheel drive state signal value successfully matches a four-wheel drive state signal value corresponding to a first four-wheel drive mode, the first four-wheel drive mode being one of the target four-wheel drive modes; The first indication information is used to indicate that the current four-wheel drive mode is the first four-wheel drive mode.

[0020] In a third aspect, an embodiment of the present disclosure provides a vehicle, comprising: a processing module; a storage module for storing executable instructions of the processing module; the processing module is used to read the executable instructions from the storage module and execute the executable instructions to implement the display control method of the intelligent four-wheel drive switch as described in the first aspect.

[0021] In a fourth aspect, an embodiment of the present disclosure provides a computer-readable storage medium, wherein the storage medium stores a computer program, and the computer program is used to implement the display control method of the intelligent four-wheel drive switch as described in the first aspect.

[0022] Through the above technical solution, the display control method, device, vehicle and storage medium of the intelligent four-wheel drive switch provided by the present disclosure represent different four-wheel drive modes by setting different four-wheel drive status signal values, and save the current four-wheel drive status signal value when the whole vehicle is powered off. The saved four-wheel drive status signal value reflects the four-wheel drive mode of the vehicle before the whole vehicle is powered off. When the whole vehicle is powered on again, the intelligent four-wheel drive switch obtains the four-wheel drive status signal value saved when the whole vehicle was powered off last, and matches the four-wheel drive status signal value with the four-wheel drive status signal value corresponding to the target four-wheel drive mode. If the obtained four-wheel drive status signal value successfully matches the four-wheel drive status signal value corresponding to the first four-wheel drive mode in the target four-wheel drive mode, it can be determined that the vehicle was in the first four-wheel drive mode when the whole vehicle was powered off last. In this case, Under this circumstance, the intelligent four-wheel drive switch directly outputs the first indication information for indicating that the current four-wheel drive mode is the first four-wheel drive mode. From the user's perspective, the display status of the intelligent four-wheel drive switch after the vehicle is powered on is consistent with the display status before the vehicle was powered off last time, thereby achieving the effect of the intelligent four-wheel drive switch memorizing the four-wheel drive mode. In addition, since different four-wheel drive status signal values ​​are set to correspond to different four-wheel drive modes, 2WD mode and AWD mode correspond to different four-wheel drive status signal values. Therefore, the four-wheel drive status signal value before the vehicle was powered off last is saved for display control of the intelligent four-wheel drive switch. The corresponding four-wheel drive mode can be uniquely determined according to the saved four-wheel drive status signal value, so that the 2WD mode and AWD mode can be accurately distinguished, and the accurate display of the four-wheel drive mode on the intelligent four-wheel drive switch end is realized.

[0023] The above description is only an overview of the technical solution of the present disclosure. In order to more clearly understand the technical means of the present disclosure, it can be implemented in accordance with the contents of the specification.

DETAILED DESCRIPTION

[0026] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure.

The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments."

[0030] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0031] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0032] The display control method, device, vehicle and storage medium of the intelligent four-wheel drive switch provided by the present disclosure are explained in detail below with reference to the accompanying drawings.

[0033] With the continuous advancement of automotive technology, the configuration of four-wheel drive vehicles has continued to change, and the transfer case has gradually been upgraded from a part-time four-wheel drive system to an intelligent four-wheel drive system. The four-wheel drive mode of the part-time four-wheel drive system includes 2WD mode, 4WD mode, and 4WD Low Range mode (4L). In 4L mode, the majority of the power is distributed to the rear axle, allowing the vehicle to obtain greater torque and enhance off-road performance. This makes it ideal for low-speed driving or situations requiring high traction, such as climbing or off-roading. 4L mode fully demonstrates the dynamic performance of a four-wheel drive vehicle, allowing it to easily handle complex terrain. 4WD mode, also known as 4WD High (4H), is more suitable for driving at higher speeds, especially in rain, snow, and uneven roads where excellent stability and grip are required. In 4H mode, all four wheels can move independently, with torque fixed at approximately 50:50 between the front and rear wheels (often referred to as Lock mode). This provides strong traction and control, higher cornering limits, and better drive force distribution, significantly enhancing vehicle handling. 2WD mode, the most basic drive mode, typically includes both front-wheel drive and rear-wheel drive. In this mode, the front and rear wheels are driven by the same drive shaft. The position of the transfer case motor varies depending on the four-wheel drive mode.

[0034] Compared with the part-time four-wheel drive system, the intelligent four-wheel drive system has added an AWD mode to its four-wheel drive mode. That is, the four-wheel drive mode of the intelligent four-wheel drive system includes 2WD mode, 4H mode, AWD mode and 4L mode. In AWD mode, the torque of the front and rear wheels can be intelligently adjusted and distributed on demand according to the driving conditions.

[0035] In a time-sharing four-wheel drive system, since the motor position of the transfer case is different in different four-wheel drive modes, the corresponding four-wheel drive mode can be determined according to the motor position and the four-wheel drive switch display can be performed, thereby achieving the four-wheel drive mode memory function at the four-wheel drive switch end. However, in an intelligent four-wheel drive system, the motor position of the transfer case in AWD mode is the same as the motor position in 2WD mode. Therefore, the original time-sharing four-wheel drive switch display strategy cannot achieve accurate display of AWD mode and 2WD mode in the intelligent four-wheel drive system, and the existing intelligent four-wheel drive disclosure does not have a four-wheel drive mode memory function. If the four-wheel drive mode memory effect perceived by the user is to be achieved, the four-wheel drive mode display strategy of the intelligent four-wheel drive switch needs to be re-formulated. Based on this, the present disclosure provides a display control solution for an intelligent four-wheel drive switch.

[0036] The display control scheme of the intelligent four-wheel drive switch provided by the present disclosure sets different four-wheel drive modes corresponding to different four-wheel drive status signal values, and saves the current four-wheel drive mode status signal when the vehicle is powered off. When the vehicle is powered on again, the intelligent four-wheel drive switch performs display control based on the four-wheel drive status signal value before the vehicle was last powered off to indicate the current four-wheel drive mode. Through the scheme of the present disclosure, although the intelligent four-wheel drive switch does not have a memory function, the four-wheel drive mode display control strategy provided by this scheme can achieve the four-wheel drive mode display of the intelligent four-wheel drive switch to be consistent with the four-wheel drive mode before the vehicle was last powered off after being powered on again in any of the four-wheel drive modes of 2WD, 4H, AWD, and 4L, achieving a four-wheel drive mode memory effect in the user's senses. In addition, one four-wheel drive status signal value uniquely corresponds to one four-wheel drive mode. Therefore, the intelligent four-wheel drive switch can uniquely determine the corresponding four-wheel drive mode based on the obtained four-wheel drive status signal value and display the four-wheel drive mode on the switch, avoiding the situation where the 2WD mode and AWD mode cannot be distinguished, and realizing accurate switch display of the four-wheel drive mode.

[0037] Figure 1 This is a flow chart of a display control method for an intelligent four-wheel drive switch provided in an exemplary embodiment of the present disclosure. This method can be executed by a display control device for an intelligent four-wheel drive switch provided in an embodiment of the present disclosure. The device can be implemented in software and / or hardware and can be integrated into a vehicle, specifically, it can be integrated into an intelligent four-wheel drive switch of an intelligent four-wheel drive vehicle. It should be noted that the intelligent four-wheel drive switch in an embodiment of the present disclosure refers to a four-wheel drive switch that implements the solution of the present disclosure. The intelligent four-wheel drive switch includes a chip with data processing capabilities, which at least supports functions such as data reception and transmission, data processing, and signal output. The signal output can be the lighting (constantly on) or flashing of an indicator light on the intelligent four-wheel drive switch, or it can be an output method such as a voice message broadcast.

[0038] like Figure 1 As shown, the display control method of the intelligent four-wheel drive switch may include the following steps: Step 101 : Obtain a first four-wheel drive state signal value, wherein the first four-wheel drive state signal value is the four-wheel drive state signal value when the vehicle is last powered off.

[0039] In the disclosed embodiment, when the vehicle is powered off, the four-wheel drive state signal value corresponding to the four-wheel drive mode at the current moment will be saved.

[0040] For example, when the vehicle is powered off, the four-wheel drive controller can save the four-wheel drive status signal value for the current four-wheel drive mode. When the vehicle is powered on again, the four-wheel drive controller completes a self-test within a preset time (which can be calibrated according to actual needs, for example, 1 second) and sends the four-wheel drive status signal value saved before the vehicle was last powered off to the Controller Area Network (CAN). The saved four-wheel drive status signal value is then sent to the body control module (BCM) via the CAN bus. The BCM then sends the four-wheel drive status signal value to the intelligent four-wheel drive switch for logic judgment by the intelligent four-wheel drive switch. After the vehicle is powered on, the intelligent four-wheel drive switch performs a self-test and receives the four-wheel drive status signal value sent by the BCM (referred to as the first four-wheel drive status signal value for ease of description and distinction). It is understood that when the vehicle is powered off, the motor position of the transfer case of the intelligent four-wheel drive system remains in the state it was in before the power was off and is not reset due to the vehicle power off. Therefore, when the vehicle is powered on again, the four-wheel drive mode of the intelligent four-wheel drive system remains the same as when the vehicle was last powered off.

[0041] It should be noted that in this embodiment, the intelligent four-wheel drive switch does not process the first four-wheel drive status signal value within a preset time (which can be calibrated according to actual needs, for example, 1 second) after the vehicle is powered on, and does not display an indication message, for example, the switch indicator light does not light up or flash.

[0042] Step 102 : Match the first four-wheel drive state signal value with the four-wheel drive state signal value corresponding to the target four-wheel drive mode.

[0043] Among them, the target four-wheel drive mode is one or more preset four-wheel drive modes. When the target four-wheel drive mode is some of the four-wheel drive modes in the intelligent four-wheel drive system, the switch display memory function of the specified four-wheel drive mode can be realized. When the target four-wheel drive mode is all four-wheel drive modes in the intelligent four-wheel drive system, the switch display memory function of all four-wheel drive modes can be realized.

[0044] In this embodiment, different four-wheel drive modes correspond to different four-wheel drive status signal values, and one four-wheel drive mode uniquely corresponds to one four-wheel drive status signal value. For example, the correspondence between the four-wheel drive status signal value and the four-wheel drive mode is shown in Table 1 below: Table 1

[0045] In Table 1, "SystemOperMod" represents the variable used to transmit the four-wheel drive status signal value. The four-wheel drive status signal value is sent to the intelligent four-wheel drive switch using the "SystemOperMod = four-wheel drive status signal value" format. A four-wheel drive status signal value of 0x0 indicates the four-wheel drive mode is unknown (Mode Unknown), a four-wheel drive status signal value of 0x1 indicates a four-wheel drive system fault (System Fault), a four-wheel drive status signal value of 0x2 indicates 2WD mode (Mode 2WD), a four-wheel drive status signal value of 0x3 indicates 4WD mode (Mode 4WD), also known as 4H mode or Lock mode, a four-wheel drive status signal value of 0x4 indicates Mode Active (AWD), and a four-wheel drive status signal value of 0x5 indicates Mode 4WD Low Range (Mode 4WD Low Range), also known as 4L mode.

[0046] In this embodiment, after the intelligent four-wheel drive switch obtains the first four-wheel drive state signal value, it can match the first four-wheel drive state signal value with the four-wheel drive state signal value corresponding to the target four-wheel drive mode.

[0047] As an example, the intelligent four-wheel drive switch can match the first four-wheel drive status signal value with the four-wheel drive status signal value corresponding to the target four-wheel drive mode after the vehicle is powered on for a preset period of time. By performing the matching after the vehicle is powered on for a preset period of time (which can be set based on the duration required for the vehicle's power-on self-test and initialization), it can ensure that the intelligent four-wheel drive switch and other related components can complete self-tests and initialization, ensure that the intelligent four-wheel drive switch components are fault-free, and can implement normal display control logic.

[0048] Step 103: When the first four-wheel drive state signal value successfully matches the four-wheel drive state signal value corresponding to the first four-wheel drive mode, output first indication information, where the first four-wheel drive mode is one of the target four-wheel drive modes, wherein the first indication information is used to indicate that the current four-wheel drive mode is the first four-wheel drive mode.

[0049] In this embodiment, the first four-wheel drive state signal value is matched with the four-wheel drive state signal value corresponding to the target four-wheel drive mode. If the first four-wheel drive state signal value successfully matches the four-wheel drive state signal value corresponding to the first four-wheel drive mode, it can be determined that the current four-wheel drive mode is the first four-wheel drive mode. In this case, the intelligent four-wheel drive switch outputs indication information (referred to as first indication information for ease of description and distinction) indicating that the current four-wheel drive mode is the first four-wheel drive mode. It is understood that the first four-wheel drive mode is one of the target four-wheel drive modes.

[0050] For example, taking the correspondence between the four-wheel drive mode and the four-wheel drive status signal value defined in Table 1 as an example, assuming that the target four-wheel drive mode includes the dynamic AWD mode and the 2WD mode, the first four-wheel drive status signal value obtained by the intelligent four-wheel drive switch is 0x4. By matching it with the four-wheel drive status signal value 0x4 of the dynamic AWD mode and the four-wheel drive status signal value 0x2 of the 2WD mode respectively, it can be determined that the first four-wheel drive mode that is successfully matched is the dynamic AWD mode, and then the first indication information is output to indicate that the current four-wheel drive mode is the dynamic AWD mode.

[0051] The first indication information may be output in different forms.

[0052] As an example, outputting the first indication information may be lighting up an indicator light corresponding to the first four-wheel drive mode.

[0053] As an example, outputting the first indication information may be a voice broadcast of a message “the current four-wheel drive mode is the first four-wheel drive mode”.

[0054] The display control method of the intelligent four-wheel drive switch provided by the embodiment of the present disclosure represents different four-wheel drive modes by setting different four-wheel drive status signal values, and saves the current four-wheel drive status signal value when the whole vehicle is powered off. The saved four-wheel drive status signal value reflects the four-wheel drive mode of the vehicle before the whole vehicle is powered off. When the whole vehicle is powered on again, the intelligent four-wheel drive switch obtains the four-wheel drive status signal value saved when the whole vehicle was powered off last time, and matches the four-wheel drive status signal value with the four-wheel drive status signal value corresponding to the target four-wheel drive mode. If the obtained four-wheel drive status signal value successfully matches the four-wheel drive status signal value corresponding to the first four-wheel drive mode in the target four-wheel drive mode, it can be determined that the vehicle was in the first four-wheel drive mode when the whole vehicle was powered off last time. In this case, the intelligent four-wheel drive switch The switch directly outputs the first indication information for indicating that the current four-wheel drive mode is the first four-wheel drive mode. From a user's perspective, the display status of the intelligent four-wheel drive switch after the vehicle is powered on is consistent with the display status before the vehicle was powered off last time, thereby achieving the effect of the intelligent four-wheel drive switch memorizing the four-wheel drive mode. In addition, since different four-wheel drive status signal values ​​are set to correspond to different four-wheel drive modes, 2WD mode and AWD mode correspond to different four-wheel drive status signal values. Therefore, the four-wheel drive status signal value before the vehicle was powered off last time is saved for display control of the intelligent four-wheel drive switch. The corresponding four-wheel drive mode can be uniquely determined according to the saved four-wheel drive status signal value, thereby accurately distinguishing between 2WD mode and AWD mode, and realizing accurate display of the four-wheel drive mode on the intelligent four-wheel drive switch end.

[0055] When the vehicle is powered off, if a four-wheel drive system failure occurs, the four-wheel drive status signal value saved by the four-wheel drive controller may be a signal value used to indicate a system failure (for example, 0x1 in Table 1). In this case, when the vehicle is powered on again, the first four-wheel drive status signal value obtained by the intelligent four-wheel drive switch cannot successfully match the four-wheel drive status signal value of the target four-wheel drive mode, and the intelligent four-wheel drive switch cannot determine the current four-wheel drive mode. This requires the intelligent four-wheel drive switch to send a specified switch status signal value to the four-wheel drive controller so that the four-wheel drive controller can activate the corresponding four-wheel drive mode. Therefore, in an optional embodiment of the present disclosure, if Figure 2 As shown, based on the above embodiment, the display control method of the intelligent four-wheel drive switch disclosed in the present invention may further include the following steps: Step 201 : when the first four-wheel drive state signal value fails to match the four-wheel drive state signal value corresponding to the target four-wheel drive mode, a preset switch state signal value is obtained.

[0056] Among them, the preset switch state signal value can be pre-set according to actual needs, and the preset switch state signal value uniquely corresponds to one four-wheel drive mode.

[0057] In the embodiment of the present disclosure, different switch state signal values ​​correspond to different four-wheel drive modes, and one switch state signal value uniquely corresponds to one four-wheel drive mode. As an example, the corresponding relationship between the switch state signal value and the four-wheel drive mode is shown in Table 2 below: Table 2

[0058] In Table 2, FDrvModSwtReq represents the variable used to transmit the switch status signal value. The switch status signal value is sent to the four-wheel drive controller using the format "FDrvModSwtReq = switch status signal value." The switch status signal value 0x1 is a reserved signal value, indicating that the signal value is not currently used. The meanings of other switch status signal values ​​are the same as in Table 1 and are not further explained here.

[0059] As can be seen from Tables 1 and 2, in the embodiments of the present disclosure, the same switch state signal value and four-wheel drive state signal value are defined for the same four-wheel drive mode. This simplifies the judgment logic of the four-wheel drive controller and the intelligent four-wheel drive switch in determining the corresponding four-wheel drive mode based on the four-wheel drive state signal value and the switch state signal value, thereby reducing the probability of mode judgment errors. However, it should be noted that Tables 1 and 2 are merely examples to illustrate the present disclosure and are not intended to limit the present disclosure. The same four-wheel drive mode may also correspond to different switch state signal values ​​and four-wheel drive state signal values. For example, for the 2WD mode, the corresponding four-wheel drive state signal value is set to 0x2, while the corresponding switch state signal value is set to 0x8.

[0060] In the embodiment of the present disclosure, if the first four-wheel drive status signal value obtained by the intelligent four-wheel drive switch fails to match the four-wheel drive status signal value corresponding to the target four-wheel drive mode, a preset switch status signal value is obtained. For example, taking the switch status signal value defined in Table 2 as an example, the preset switch status signal value can be set to 0x2.

[0061] For example, taking the correspondence between the four-wheel drive modes and the four-wheel drive status signal values ​​defined in Table 1 as an example, assuming that the target four-wheel drive modes include 2WD mode, 4H mode, dynamic AWD mode and 4L mode, and the first four-wheel drive status signal value obtained by the intelligent four-wheel drive switch is 0x1, then by matching the first four-wheel drive status signal value 0x1 with the four-wheel drive status signal values ​​of each target four-wheel drive mode respectively, it can be determined that SystemOperMod≠0x2 / 0x3 / 0x4 / 0x5, that is, the first four-wheel drive status signal value fails to match the four-wheel drive status signal values ​​of all target four-wheel drive modes. In this case, the intelligent four-wheel drive switch obtains the preset switch status signal value.

[0062] Step 202 : Send a preset switch state signal value to the four-wheel drive controller and output second indication information, where the second indication information is used to indicate that the second four-wheel drive mode corresponding to the preset switch state signal value is currently in the startup process.

[0063] In this embodiment, after the intelligent four-wheel drive switch obtains the preset switch state signal value, it sends the preset switch state signal value to the four-wheel drive controller, and outputs indication information (for the convenience of description and distinction, called the second four-wheel drive mode) during the startup process for indicating the four-wheel drive mode corresponding to the preset switch state signal value. The second four-wheel drive mode is a four-wheel drive mode among the four-wheel drive modes supported by the intelligent four-wheel drive system that corresponds to the preset switch state signal value.

[0064] For example, assuming that the preset switch state signal value is 0x2, the intelligent four-wheel drive switch sends a signal of "FDrvModSwtReq=0x2" to the BCM, and the BCM forwards the signal to the four-wheel drive controller.

[0065] It can be understood that the second indication information can be output in different forms.

[0066] As an example, outputting the second indication information may be controlling an indicator light corresponding to the second four-wheel drive mode to flash according to a preset period (eg, 1 second).

[0067] As an example, outputting the second indication information may be a voice broadcast of a message “the second four-wheel drive mode is being started, please wait”.

[0068] It is understood that after the four-wheel drive controller receives the preset switch state signal value sent by the intelligent four-wheel drive switch, it will determine the corresponding four-wheel drive mode according to the preset switch state signal value and start the four-wheel drive mode. After successful startup, the four-wheel drive state signal value corresponding to the four-wheel drive mode (for ease of description and distinction, referred to as the second four-wheel drive state signal value) is returned to the intelligent four-wheel drive switch to inform the intelligent four-wheel drive switch that the corresponding four-wheel drive mode is currently started. Therefore, in an optional embodiment of the present disclosure, if Figure 2 As shown, after the intelligent four-wheel drive switch sends the preset switch state signal value, the display control method of the intelligent four-wheel drive switch may further include the following steps: Step 203 : Acquire a second four-wheel drive state signal value, where the second four-wheel drive state signal value is a response made by the four-wheel drive controller after receiving a preset switch state signal value.

[0069] In this embodiment, after receiving the preset switch state signal value, the four-wheel drive controller starts the second four-wheel drive mode corresponding to the preset switch state signal value and returns the four-wheel drive state signal value corresponding to the second four-wheel drive mode (for the convenience of description and distinction, referred to as the second four-wheel drive state signal value).

[0070] Step 204 : When the third four-wheel drive mode corresponding to the second four-wheel drive state signal value is the same as the second four-wheel drive mode, output third indication information, where the third indication information is used to indicate that the current four-wheel drive mode is the second four-wheel drive mode.

[0071] In this embodiment, after the intelligent four-wheel drive switch receives the second four-wheel drive status signal value, it determines the four-wheel drive mode corresponding to the second four-wheel drive status signal value (for the convenience of description and distinction, called the third four-wheel drive mode), and compares whether the third four-wheel drive mode is the same as the second four-wheel drive mode. If they are the same, it outputs an indication message indicating that the current four-wheel drive mode is the second four-wheel drive mode (for the convenience of description and distinction, called the third indication message). The third four-wheel drive mode is a four-wheel drive mode among the four-wheel drive modes supported by the intelligent four-wheel drive system that corresponds to the second four-wheel drive status signal value.

[0072] As an example, assuming that outputting the second indication message is to control the indicator light corresponding to the second four-wheel drive mode to flash according to a preset period (for example, 1 second), then outputting the third indication message can be to light up the indicator light corresponding to the second four-wheel drive mode after the indicator light flashes the current period, that is, to control the indicator light corresponding to the second four-wheel drive mode from flashing to constantly on.

[0073] As an example, assuming that the output second indication message is a voice broadcast message of "the second four-wheel drive mode is starting, please wait", the output third indication message may be a voice broadcast message of "the second four-wheel drive mode has been successfully started".

[0074] It can be understood that the intelligent four-wheel drive switch periodically sends the switch status signal value to the four-wheel drive controller. Therefore, in this embodiment, if the intelligent four-wheel drive switch determines that the third four-wheel drive mode is inconsistent with the second four-wheel drive mode, it will still send the preset switch status signal value to the four-wheel drive controller and output the second indication message.

[0075] The display control method of the intelligent four-wheel drive switch of the disclosed embodiment sends a preset switch state signal value to the four-wheel drive controller when a first four-wheel drive state signal value fails to match a four-wheel drive state signal value corresponding to a target four-wheel drive mode, and outputs an indication message indicating that the vehicle is currently in the process of activating a second four-wheel drive mode corresponding to the preset switch state signal value. This method can remind a user of the four-wheel drive mode currently being activated, allowing the user to intuitively know which four-wheel drive mode is being activated. After receiving the preset switch state signal value, the four-wheel drive controller activates the corresponding four-wheel drive mode and returns the corresponding second four-wheel drive state signal value to the intelligent four-wheel drive switch. If the intelligent four-wheel drive switch determines that the third four-wheel drive mode corresponding to the second four-wheel drive state signal value is the same as the second four-wheel drive mode, the intelligent four-wheel drive switch outputs an indication message indicating that the current four-wheel drive mode is the second four-wheel drive mode. This method facilitates the user to intuitively know which four-wheel drive mode has been successfully activated. Furthermore, different indication messages are output during and after the four-wheel drive mode is successfully activated, allowing the user to intuitively know the four-wheel drive mode activation process, thereby improving the user experience.

[0076] The four-wheel drive mode before the vehicle was powered off last time or the four-wheel drive mode activated by the smart four-wheel drive switch by default may not be the four-wheel drive mode the user expects during this driving. In this case, the user can switch the four-wheel drive mode through the smart four-wheel drive switch. The smart four-wheel drive switch sends a corresponding switch state signal value to the four-wheel drive controller according to the four-wheel drive mode switched by the user, so that the four-wheel drive controller switches the four-wheel drive mode to the corresponding four-wheel drive mode. Therefore, in an optional embodiment of the present disclosure, if Figure 3 As shown, based on the above embodiment, the display control method of the intelligent four-wheel drive switch disclosed in the present invention may further include the following steps: Step 301 : In response to receiving a user's switching operation for a fourth four-wheel drive mode, obtaining a second switch state signal value corresponding to the fourth four-wheel drive mode.

[0077] The fourth four-wheel drive mode is a four-wheel drive mode switched by the user and is one of the four-wheel drive modes supported by the intelligent four-wheel drive system. For example, the user can switch to the fourth four-wheel drive mode by rotating the intelligent four-wheel drive switch to the position of the desired four-wheel drive mode (referred to as the fourth four-wheel drive mode), or the user can switch to the fourth four-wheel drive mode by clicking the button corresponding to the desired fourth four-wheel drive mode on the intelligent four-wheel drive switch. Alternatively, the user can switch to the fourth four-wheel drive mode through voice commands, for example, the user can initiate a voice command "switch to low-speed four-wheel drive mode" to switch to 4L mode.

[0078] Step 302: Send a second switch state signal value to the four-wheel drive controller and output fourth indication information, where the fourth indication information is used to indicate that the fourth four-wheel drive mode is currently in the switching process.

[0079] In this embodiment, after the intelligent four-wheel drive switch receives the user's switching operation to the fourth four-wheel drive mode, it responds to the operation, obtains the switch state signal value corresponding to the fourth four-wheel drive mode (for the convenience of description and distinction, referred to as the second switch state signal value), and sends the second switch state signal value to the four-wheel drive controller, and outputs indication information for indicating that it is currently in the switching process of the fourth four-wheel drive mode (for the convenience of description and distinction, referred to as the fourth indication information).

[0080] Exemplarily, the intelligent four-wheel drive switch may output the fourth indication information by controlling the indicator light corresponding to the fourth four-wheel drive mode to flash.

[0081] Exemplarily, the intelligent four-wheel drive switch may output the fourth indication information by voice broadcasting a message “Switching to the fourth four-wheel drive mode, please wait”.

[0082] After receiving the second switch state signal value, the four-wheel drive controller switches the four-wheel drive mode to the fourth four-wheel drive mode corresponding to the second switch state signal value, and obtains the four-wheel drive state signal value corresponding to the fourth four-wheel drive mode (for ease of description and distinction, referred to as the third four-wheel drive state signal value) and returns it to the intelligent four-wheel drive switch, so that the intelligent four-wheel drive switch can perform switch display control according to the third four-wheel drive state signal value. Figure 3 As shown, the display control method of the intelligent four-wheel drive switch may further include the following steps: Step 303: Obtain a third four-wheel drive state signal value.

[0083] Among them, the third four-wheel drive status signal value is the four-wheel drive status signal value corresponding to the fourth four-wheel drive mode obtained after the four-wheel drive controller responds to the second switch status signal value sent by the intelligent four-wheel drive switch and switches the four-wheel drive mode to the fourth four-wheel drive mode corresponding to the second switch status signal value.

[0084] Step 304 : After the display duration of the fourth indication information reaches a preset duration, it is determined whether the fifth four-wheel drive mode corresponding to the third four-wheel drive state signal value is the same as the fourth four-wheel drive mode.

[0085] The preset duration can be pre-set based on actual needs, and this disclosure does not impose any restrictions on its specific value. For example, the preset duration can be set based on the time required for the four-wheel drive controller to switch to the four-wheel drive mode. The preset duration can be set slightly longer than the time required to switch the four-wheel drive mode to ensure that the four-wheel drive controller can complete the four-wheel drive mode switch when the intelligent four-wheel drive switch performs switch display control based on the third four-wheel drive status signal value. For example, the preset duration can be set to 3 seconds.

[0086] In this embodiment, after the intelligent four-wheel drive switch outputs the fourth indication information, it starts timing, and after receiving the third four-wheel drive status signal value sent by the four-wheel drive controller and the display duration of the fourth indication information reaches a preset duration, it is determined whether the four-wheel drive mode corresponding to the third four-wheel drive status signal value (referred to as the fifth four-wheel drive mode for ease of description and distinction) is the same as the fourth four-wheel drive mode switched by the user. If they are the same, step 305 is executed; if they are not the same, the fourth indication information is continuously output, and when the transmission cycle of the switch status signal value is reached, the second switch status signal value is continuously sent to the four-wheel drive controller, and the third four-wheel drive status signal value returned by the four-wheel drive controller is waited for. The fifth four-wheel drive mode is a four-wheel drive mode supported by the intelligent four-wheel drive system that corresponds to the third four-wheel drive status signal value.

[0087] Step 305 : When the fifth four-wheel drive mode is the same as the fourth four-wheel drive mode, output fifth indication information, where the fifth indication information is used to indicate that the current four-wheel drive mode is the fourth four-wheel drive mode.

[0088] In this embodiment, when the intelligent four-wheel drive switch determines that the fifth four-wheel drive mode is the same as the fourth four-wheel drive mode, it outputs indication information (referred to as the fifth indication information for ease of description and distinction) indicating that the current four-wheel drive mode is in the fourth four-wheel drive mode.

[0089] As an example, assuming a preset duration of 3 seconds, the intelligent 4WD switch outputs different indication messages by controlling the indicator lights corresponding to the 4WD modes to display different displays. After obtaining the second switch status signal value corresponding to the fourth 4WD mode, the intelligent 4WD switch controls the indicator light corresponding to the fourth 4WD mode to flash for 3 seconds and sends the second switch status signal value to the 4WD controller. After 3 seconds, the intelligent 4WD switch compares the fifth 4WD mode, corresponding to the third 4WD status signal value returned by the 4WD controller, with the fourth 4WD mode. If the two modes match, the intelligent 4WD switch illuminates the indicator light corresponding to the fourth 4WD mode (i.e., permanently on). Considering that the indicator light is still flashing while the intelligent 4WD switch compares the fourth and fifth 4WD modes, after determining that the fourth and fifth 4WD modes are the same, the intelligent 4WD switch waits for the indicator light to complete its current flashing cycle (i.e., the duration required for the indicator light to flash once, e.g., 1 second) before controlling the indicator light to remain on. This ensures that the duration of each flashing of the indicator light is consistent. If the fourth four-wheel drive mode and the fifth four-wheel drive mode are different, the second switch state signal value continues to be sent to the four-wheel drive controller when the sending cycle of the switch state signal value is reached.

[0090] The display control method of the intelligent four-wheel drive switch of the embodiment of the present disclosure is that when the user switches the four-wheel drive mode to the fourth four-wheel drive mode, the intelligent four-wheel drive switch sends a second switch state signal value corresponding to the fourth four-wheel drive mode to the four-wheel drive controller, and outputs fourth indication information for indicating that it is currently in the switching process of the fourth four-wheel drive mode. It can output the current four-wheel drive mode state, so that the user can easily know that it is currently in the switching process of the fourth four-wheel drive mode; after the intelligent four-wheel drive switch receives the third four-wheel drive state signal value sent by the four-wheel drive controller and the display time of the fourth indication information reaches a preset time, it determines whether the fifth four-wheel drive mode corresponding to the third four-wheel drive state signal value is the same as the fourth four-wheel drive mode, and then determines whether the fifth four-wheel drive mode corresponding to the third four-wheel drive state signal value is the same as the fourth four-wheel drive mode by etc. The judgment logic is executed after a preset time, which reserves sufficient time for the four-wheel drive controller to switch the four-wheel drive mode. It can ensure that the four-wheel drive controller has completed the four-wheel drive mode switching operation and returned the corresponding four-wheel drive status signal value at this time, and can also avoid unnecessary judgment operations when the user continuously switches the four-wheel drive mode; after judging that the fifth four-wheel drive mode is the same as the fourth four-wheel drive mode, the intelligent four-wheel drive switch outputs the fifth indication message for indicating that the current four-wheel drive mode is in the fourth four-wheel drive mode, which provides convenience for the user to know the current four-wheel drive mode; and different indication messages are output during the four-wheel drive mode switching process and after the successful switching, which can enable the user to intuitively know the four-wheel drive mode switching process and enhance the user experience.

[0091] When the user switches the four-wheel drive mode, there may be other four-wheel drive modes between the current four-wheel drive mode and the four-wheel drive mode desired by the user. The user needs to switch the four-wheel drive mode to the desired four-wheel drive mode in sequence, that is, the user may need to cross at least one four-wheel drive mode before switching to the desired four-wheel drive mode. Every time the user switches a four-wheel drive mode, an indication message indicating the switching process of the current four-wheel drive mode will be output and the timing will be restarted. Therefore, in an optional embodiment of the present disclosure, in the case of Figure 3 On the basis of the illustrated embodiment, the display control method of the intelligent four-wheel drive switch disclosed in the present invention also includes: before the display duration of the fourth indication information reaches the preset duration, in response to receiving the user's switching operation for the sixth four-wheel drive mode, obtaining the switch state signal value corresponding to the sixth four-wheel drive mode (for the convenience of description and distinction, referred to as the third switch state signal value), outputting the sixth indication information and restarting the timing, the sixth indication information is used to indicate that the current switching process is in the sixth four-wheel drive mode, wherein the sixth four-wheel drive mode is one of the four-wheel drive modes supported by the intelligent four-wheel drive system; accordingly, the intelligent four-wheel drive switch also sends the third switch state signal value to the four-wheel drive controller, so that after the four-wheel drive controller receives the third switch state signal value, it switches the four-wheel drive mode to the four-wheel drive mode corresponding to the third switch state signal value, and returns the four-wheel drive state signal value corresponding to the four-wheel drive mode to the intelligent four-wheel drive switch. After the intelligent four-wheel drive switch receives the four-wheel drive status signal value returned by the four-wheel drive controller, if the display time of the sixth indication information has reached the preset time, the four-wheel drive mode corresponding to the four-wheel drive status signal value is compared with the sixth four-wheel drive mode. If the two are consistent, the indication information that the current four-wheel drive mode is the sixth four-wheel drive mode is output to inform the user that the four-wheel drive mode switching is successful. If the two are inconsistent, the sixth indication information continues to be output to inform the user that the current four-wheel drive mode is still in the switching process of the sixth four-wheel drive mode.

[0092] In an embodiment of the present disclosure, if the user performs a switching operation to the sixth four-wheel drive mode before the display duration of the fourth indication information reaches the preset duration, indication information for indicating that the user is currently in the switching process of the sixth four-wheel drive mode is output to ensure that the output indication information matches the four-wheel drive mode switched by the user, and the timing is restarted after the indication information is output, so as to match the four-wheel drive mode after the display duration of the restarted indication information reaches the preset duration, thereby ensuring that the display duration of the indication information related to the new switching mode can also reach the preset duration, thereby reserving sufficient time for the four-wheel drive controller to switch the four-wheel drive mode, and ensuring that the intelligent four-wheel drive switch can receive the four-wheel drive status signal value responded by the four-wheel drive controller within the preset duration.

[0093] In an optional embodiment of the present disclosure, the target four-wheel drive mode described in the aforementioned embodiment includes a two-wheel drive mode (2WD), a four-wheel drive high-speed mode (4H), an intelligent four-wheel drive mode (AWD), and a four-wheel drive low-speed mode (4L). The AWD mode refers to a four-wheel drive mode in which torque distribution between the front and rear wheels is intelligently adjusted and distributed based on driving conditions. The intelligent four-wheel drive switch matches the four-wheel drive status signal value stored when the vehicle was last powered off with the four-wheel drive status signal value corresponding to the target four-wheel drive mode. If a match is found, the intelligent four-wheel drive switch outputs an indication message indicating that the current four-wheel drive mode is the four-wheel drive mode corresponding to the successfully matched four-wheel drive status signal value, such as by lighting an indicator light corresponding to the four-wheel drive mode, to facilitate user notification of the current four-wheel drive mode. This allows the vehicle to be powered on again in any of the four-wheel drive modes of 2WD, 4H, AWD, or 4L, and the four-wheel drive mode displayed on the intelligent four-wheel drive switch to be consistent with the four-wheel drive mode displayed before the vehicle was last powered off, thus achieving the effect of memorizing the four-wheel drive mode.

[0094] It should be noted that in the disclosed embodiment, after the vehicle is powered on for a period of time (e.g., 1 second), if the intelligent 4WD switch fails to receive the 4WD status signal value from the BCM for a period exceeding a predetermined time period—for example, if the intelligent 4WD switch fails to receive the 4WD status signal value forwarded by the BCM for 10 consecutive cycles (maximum 500 milliseconds), the intelligent 4WD switch determines that the signal value is lost. In this case, the intelligent 4WD switch continues to transmit the switch status signal value for the current 4WD mode and outputs an indication indicating that the vehicle is currently in the startup process for the current 4WD mode. For example, if the intelligent 4WD switch transmits the switch status signal value for the 2WD mode and fails to receive a return 4WD status signal value for 10 consecutive cycles, the intelligent 4WD switch continues to transmit the switch status signal value for the 2WD mode at a predetermined period and controls the indicator light corresponding to the 2WD mode to flash to alert the user. Even after determining that the signal value is lost, the intelligent 4WD switch can still receive the user's operation to switch the 4WD mode, controls the indicator light corresponding to the selected 4WD mode to flash, and transmits the switch status signal value corresponding to the selected 4WD mode to the 4WD controller.

[0095] In order to implement the above embodiments, the present disclosure also provides a display control device for an intelligent four-wheel drive switch.
