[0002] The transfer case is an important transmission component for the vehicle to switch between high-speed two-wheel drive mode and low-speed four-wheel drive mode. The main control process of the current four-wheel drive system control strategy is: the user triggers the switch of the drive mode through the HUT soft switch, and a soft switch operation signal will be issued at this time. The vehicle will synchronously activate the activation signal based on the received soft switch operation signal and output the signal value of the drive mode switch signal corresponding to the drive mode the user wants to switch to. The activation signal will activate the four-wheel drive system to respond to the signal value of the drive mode switch signal, and the signal value of the drive mode switch signal will correspondingly control the four-wheel drive system to perform the corresponding control action to switch the vehicle to the drive mode the user wants to switch to. However, in actual application, there will be occasional situations where the four-wheel drive system does not respond to the HUT soft switch, causing customer complaints. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] refer to Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a method for switching a driving mode according to an embodiment of the present application. Figure 1 As shown, the present application provides a method for switching a driving mode, comprising:

[0043] Step S1: according to the received soft switch operation signal, activating the activation signal and outputting the signal value of the driving mode switching signal, wherein the activation signal is a signal for controlling the vehicle to start executing the driving mode switching process.

[0044] Step S2: Detecting the signal value of the output drive mode switching signal according to the activation status of the activation signal.

[0045] Step S3: Based on the signal value of the driving mode switching signal obtained by detection, a target signal value to be stabilized is determined.

[0046] Step S4: controlling the vehicle to execute a corresponding driving mode switching action according to the target signal value.

[0047] In this embodiment, a method for switching a driving mode provided by the present application is applicable to a scenario in which a vehicle (such as a four-wheel drive vehicle) switches between 2H (two-wheel drive high-speed mode) and 4L (four-wheel drive low-speed mode). Here, a four-wheel drive vehicle with two driving modes of 2H and 4L is taken as an example to describe the driving mode switching method of the present application in detail. First, a module for receiving a soft switch operation signal input by a user is integrated into the four-wheel drive system of the four-wheel drive vehicle. Specifically, a soft switch for switching to 2H mode and a soft switch for switching to 4L mode are respectively provided on the human-computer interaction interface (HUT Head-Up Display) of the vehicle. When the user needs to switch the driving mode, he only needs to click the corresponding soft switch on the HUT to trigger the corresponding soft switch operation signal.

[0048] For example, when the user wants to switch the vehicle from the current drive mode to the 2H mode, he will click the "2H mode" soft switch on the HUT. At this time, the signal receiving module in the four-wheel drive system will capture this soft switch operation signal and pass it as input to the subsequent processing flow. Next, the four-wheel drive system will activate the activation signal according to the received soft switch operation signal, and output the signal value of the drive mode switching signal corresponding to the soft switch operation signal. In this example, since the user clicked the "2H mode" soft switch, the four-wheel drive system will output a signal value of the drive mode switching signal corresponding to the 2H mode. Subsequently, the four-wheel drive system begins to detect the signal value of the output drive mode switching signal based on the activation of the activation signal. This process usually involves real-time monitoring and verification of the signal value to ensure its accuracy and reliability. Once a stable and no longer changing signal value of the drive mode switching signal is detected, the four-wheel drive system determines the signal value as the target signal value for controlling the vehicle to perform the corresponding drive mode switching action. In this example, the target signal value is the signal value required to control the vehicle to switch from the current drive mode to the 2H mode.

[0049] Finally, the four-wheel drive system sends the target signal value to the vehicle's drive system to control the vehicle to perform the corresponding drive mode switching action. Specifically, after receiving the target signal value, the vehicle's drive system will adjust the transmission ratio, torque distribution and other parameters to achieve a smooth switch from the current drive mode to the 2H mode.

[0050] Similarly, when the user wants to switch the vehicle to 4L mode, he only needs to click the "4L Mode" soft switch on the HUT, and the four-wheel drive system will perform the corresponding drive mode switching action according to the same process.

[0051] In this embodiment, an optional implementation of step S1 in a method for switching a driving mode provided in this application is that after receiving a soft switch operation signal, the activation of the activation signal and the output of the signal value of the driving mode switching signal are performed synchronously. Specifically: an activation signal for controlling the driving mode switching is provided inside the four-wheel drive system. When the soft switch operation signal is received, the four-wheel drive system will immediately activate the activation signal, that is, change its state from "unactivated" to "activated". This operation marks the official start of the driving mode switching process. While the activation signal is activated, the four-wheel drive system will output a signal value of a driving mode switching signal corresponding to the content of the received soft switch operation signal (that is, the driving mode that the user wants to switch to). In this example, since the user clicks the "2H mode" soft switch, the four-wheel drive system will output a signal value of a driving mode switching signal corresponding to the 2H mode.

[0052] These two operations are performed synchronously, that is, they are completed almost at the same time as the soft switch operation signal is received. Subsequently, the four-wheel drive system will determine the target signal value for controlling the vehicle to perform the corresponding drive mode switching action based on the activation status of the activation signal and the signal value of the detected drive mode switching signal (corresponding to the 2H mode). Finally, by sending the target signal value to the vehicle's drive system, the vehicle is controlled to perform the switching action from the current drive mode to the 2H mode.

[0053] The embodiment of the present application provides a method for driving mode switching, firstly, according to the received soft switch operation signal, activates the activation signal and outputs the signal value of the driving mode switching signal, wherein the activation signal is a signal for controlling the vehicle to start executing the driving mode switching process; according to the activation status of the activation signal, detects the signal value of the output driving mode switching signal; based on the signal value of the driving mode switching signal obtained by the detection, determines the stable target signal value; through the target signal value, controls the vehicle to execute the corresponding driving mode switching action. Therefore, when the method for driving mode switching provided by the present application detects the signal value of the mode switching signal after the activation signal is activated, the signal value detected immediately will not be determined as the target signal value that needs to control the vehicle to switch to the corresponding driving mode, but needs to wait for it to stabilize and no longer change, and then determine the stable signal value as the target signal value that finally controls the vehicle to switch to the corresponding driving mode, which can avoid the four-wheel drive system from not knowing which signal value needs to be based on to execute the driving mode switching action due to the detection of multiple signal values ​​after activation, thereby ensuring the accuracy and stability of the vehicle driving mode switching.

[0054] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for driving mode switching. In the method for driving mode switching, step S2 and step S3 may include: after the activation signal is activated, detecting the signal value of the output driving mode switching signal; and determining the signal value of the first driving mode switching signal obtained by the detection as the stable target signal value.

[0055] In this embodiment, for the current four-wheel drive system control strategy, the present application finds that the reason why the switching of the driving mode of the vehicle is occasionally unable to execute the switching action of the driving mode is that although the current four-wheel drive system control strategy is to synchronously activate the activation signal and output the signal value of the driving mode switching signal, occasionally the signal value of the output driving mode switching signal is later than the activation of the activation signal, resulting in the four-wheel drive system detecting two signal values ​​of the output driving mode switching signal during the activation of the activation signal, and the two signals are respectively the signal value of the output driving mode switching signal in response to the soft switch operation signal, and the signal value of the driving mode switching signal output before the soft switch operation signal is not responded to. At this time, the four-wheel drive system will not know which signal value it should perform the driving mode switching operation based on, resulting in the failure to switch the driving mode. Therefore, in order to solve the problem of signal value detection delay that may occur during the vehicle driving mode switching process, the present application ensures that the four-wheel drive system can accurately and correctly receive the signal value of the driving mode switching signal, and control the vehicle to perform the corresponding driving mode switching action accordingly. The present application provides another implementation method for step S2 and step S3. The core idea is to start detecting the signal value of the drive mode switching signal after the activation signal is set and activated, so as to avoid the problem of detecting multiple signal values. Specifically: After receiving the soft switch operation signal, the four-wheel drive system of the present application will synchronously set the activation signal and output the signal value of the drive mode switching signal. Next, in order to avoid detecting the signal values ​​of multiple drive mode switching signals, the four-wheel drive system will detect the signal value of the output drive mode switching signal at the end setting time after the activation signal is set and activated, and directly determine the first detected signal value as the stable target signal value.

[0056] In this embodiment, a detection module is provided inside the four-wheel drive system, which is responsible for starting to detect the signal value of the drive mode switching signal when the activation signal is no longer in the activated state. Since the activation of the activation signal and the output of the drive mode switching signal are performed synchronously (although there may be a slight time difference), it can be reasonably assumed that after the activation of the activation signal is completed, the signal value of the drive mode switching signal has stabilized and can be accurately detected. Once the signal value of the drive mode switching signal is detected, the detection module will immediately capture it and pass it to the control module. The control module determines the signal value as the target signal value for controlling the vehicle to perform the corresponding drive mode switching action. Finally, by sending the target signal value to the drive system of the vehicle, the vehicle is controlled to perform a switching action from the current drive mode to the drive mode corresponding to the target signal value.

[0057] Since the present embodiment detects the signal value of the driving mode switching signal only after the activation signal is set and activated, the problem of detecting multiple signal values ​​when the signal value of the output driving mode switching signal is later than the activation of the activation signal can be effectively avoided. This design ensures that the four-wheel drive system can accurately and correctly receive the signal value of the driving mode switching signal, and control the vehicle to perform the corresponding driving mode switching action accordingly.

[0058] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for driving mode switching. In the method for driving mode switching, step S2 and step S3 may include: during the activation of the activation signal, detecting the signal value of the output driving mode switching signal; and determining the last signal value of the signal value of the driving mode switching signal obtained by the detection as the stable target signal value.

[0059] In this embodiment, for the current four-wheel drive system control strategy, the present application finds that the reason why the switching of the driving mode of the vehicle is occasionally unable to execute the switching action of the driving mode is that although the current four-wheel drive system control strategy is to synchronously activate the activation signal and output the signal value of the driving mode switching signal, occasionally the signal value of the output driving mode switching signal is later than the activation of the activation signal, resulting in the four-wheel drive system detecting two signal values ​​of the output driving mode switching signal during the activation of the activation signal, and the two signals are respectively the signal value of the output driving mode switching signal in response to the soft switch operation signal, and the signal value of the driving mode switching signal output before the soft switch operation signal is not responded to. At this time, the four-wheel drive system will not know which signal value it should perform the driving mode switching operation based on, resulting in the failure to switch the driving mode. Therefore, in order to solve the problem of signal value detection delay that may occur during the vehicle driving mode switching process, the present application ensures that the four-wheel drive system can accurately and correctly receive the signal value of the driving mode switching signal, and control the vehicle to perform the corresponding driving mode switching action accordingly. The present application provides another implementation method for step S2 and step S3. The core idea is to detect the signal value of the drive mode switching signal during the activation period of the activation signal, and determine the signal value of the last drive mode switching signal during the activation period as a stable target signal value. Specifically: After receiving the soft switch operation signal, the four-wheel drive system of the present application will synchronously activate the activation signal and output the signal value of the drive mode switching signal. Next, the four-wheel drive system will continue to detect the signal value of the drive mode switching signal during the activation period of the activation signal. When only one signal value of the output drive mode switching signal is detected during the activation period of the activation signal, it indicates that the signal value of the synchronously output drive mode switching signal is not later than the activation action of the activation signal. At this time, the signal value is determined as a stable target signal value. In the case where multiple signal values ​​of the output drive mode switching signal are detected during the activation period of the activation signal, the last signal value detected during the activation period is determined as a stable target signal value.

[0060] In this embodiment, a detection module is provided inside the four-wheel drive system, which is responsible for continuously detecting the signal value of the drive mode switching signal during the period when the activation signal is in the activated state. Since the activation of the activation signal and the output of the drive mode switching signal are performed synchronously (although there may be a slight time difference), it can be reasonably assumed that during the activation of the activation signal, the signal value of the drive mode switching signal will be in a stable state and can be accurately detected in the period after the activation of the activation signal. Once the signal value of the last drive mode switching signal during the activation of the activation signal is detected, the detection module will capture it and pass it to the control module. The control module determines the signal value as the target signal value for controlling the vehicle to perform the corresponding drive mode switching action. Finally, by sending the target signal value to the drive system of the vehicle, the vehicle is controlled to perform the switching action from the current drive mode to the drive mode corresponding to the target signal value.

[0061] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for driving mode switching. In the driving mode switching method, step S1 may include: outputting the signal value of the driving mode switching signal according to the received soft switch operation signal, and delaying the activation of the activation signal; in the case where step S1 may include outputting the signal value of the driving mode switching signal according to the received soft switch operation signal, and delaying the activation of the activation signal, steps S2 and S3 may include: during the activation of the activation signal, detecting the signal value of the output driving mode switching signal; determining the signal value of the first driving mode switching signal obtained by the detection as the stable target signal value.

[0062] In this embodiment, for the current four-wheel drive system control strategy, the present application finds that the reason why the switching of the driving mode of the vehicle is occasionally unable to execute the switching action of the driving mode is that although the current four-wheel drive system control strategy is to synchronously activate the activation signal and output the signal value of the driving mode switching signal, occasionally the signal value of the output driving mode switching signal is later than the activation of the activation signal, resulting in the four-wheel drive system detecting two signal values ​​of the output driving mode switching signal during the activation of the activation signal, and the two signals are respectively the signal value of the output driving mode switching signal in response to the soft switch operation signal, and the signal value of the driving mode switching signal output before the soft switch operation signal is not responded to. At this time, the four-wheel drive system will not know which signal value it should perform the driving mode switching operation based on, resulting in the failure to switch the driving mode. Therefore, in order to solve the problem of signal value detection delay that may occur during the vehicle driving mode switching process, the present application ensures that the four-wheel drive system can accurately and correctly receive the signal value of the driving mode switching signal, and control the vehicle to perform the corresponding driving mode switching action accordingly. The present application provides another implementation method for steps S1 to S3. The core idea is that after receiving the soft switch operation signal, the signal value of the drive mode switching signal is first output, and then the activation signal is activated after a certain delay (such as the duration corresponding to the effective value of 3 frames). Specifically: after receiving the soft switch operation signal, the four-wheel drive system will immediately output the signal value of the corresponding drive mode switching signal according to the content of the soft switch operation signal. The signal value represents the target drive mode that the user wants to switch to. Since there may be a time difference between the signal value of the synchronous output drive mode switching signal and the activation of the activation signal (the time difference is that the signal value of the output drive mode switching signal is later than the activation of the activation signal), in order to avoid the possible error processing or misjudgment of the four-wheel drive system caused by this time difference, the present application proposes to delay the activation of the activation signal. After the four-wheel drive system outputs the signal value of the drive mode switching signal, it will delay for a certain period of time (such as within 3 frames of activation setting effective value) and then set the activation signal. The selection of this delay time is to ensure that when the activation signal is activated, the signal value of the drive mode switching signal is stable and accurate. After the activation signal is activated with a delay, the four-wheel drive system will begin to detect the signal value of the output drive mode switching signal. Since the signal value of the drive mode switching signal is already stable and accurate at this time, the detected signal value can be directly determined as the target signal value. A detection module is provided inside the four-wheel drive system, which is responsible for continuously detecting the signal value of the drive mode switching signal during the activation of the activation signal. Since the activation signal is activated with a delay, it can be ensured that the signal value of the drive mode switching signal is stable when the detection module starts working. At this time, the detected signal value is determined as the target signal value for controlling the vehicle to perform the corresponding drive mode switching action.Finally, by sending the instruction or signal to the driving system of the vehicle, the vehicle is controlled to execute a switching action from the current driving mode to the target driving mode.

[0063] Since this embodiment first outputs the signal value of the drive mode switching signal after receiving the soft switch operation signal, and then activates the activation signal after a certain delay, the problem of a time difference between the output signal value of the drive mode switching signal and the activation of the activation signal can be effectively avoided. This design ensures that the four-wheel drive system can accurately and correctly receive the stable and accurate signal value of the drive mode switching signal, and control the vehicle to perform the corresponding drive mode switching action accordingly.

[0064] In combination with the above embodiments, in one implementation, the embodiment of the present application also provides a method for switching a driving mode. In the method for switching a driving mode, the method further includes: acquiring driving scene data and vehicle status data of the vehicle; analyzing the driving scene data and vehicle status data to determine the corresponding target driving mode; according to the target driving mode, outputting a corresponding soft switch operation signal to control the vehicle to switch to the target driving mode; the driving scene data includes road condition data and / or weather data; the vehicle status data includes engine speed data, and / or tire status data, and / or vehicle body posture.

[0065] In this embodiment, in order to improve the user's car experience, in addition to the user directly operating the soft switch to send a soft switch operation signal, the present application can also automatically determine and switch to the best driving mode based on the driving scene data and the vehicle status data. Specifically: first, the driving scene data and the vehicle status data are obtained through the sensor cluster carried by the vehicle and / or from the cloud. The driving scene data includes road condition data (such as highway congestion / unblocked, urban road congestion / unblocked, mountain road congestion / unblocked, etc.) and weather data (such as rain, snow, sunny days, etc.); the vehicle status data includes engine speed data, tire status data, body posture data, etc. Then, the acquired driving scene data and vehicle status data are analyzed to determine which driving mode is the best or most suitable (such as 2H driving mode, 4L driving mode, etc.) in the current driving scene and vehicle state. Based on the determined optimal target driving mode, the corresponding soft switch operation signal is output, such as when the target driving mode is the 4L driving mode, the soft switch operation signal corresponding to the 4L driving mode is output. The present application provides a driving mode switching method that can not only switch the driving mode by directly operating a soft switch by the user, but also automatically trigger a soft switch operation signal according to the driving scenario and vehicle status to achieve automatic switching of the driving mode, thereby improving the vehicle's driving performance and user experience.

[0066] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for switching a driving mode. In the method for switching a driving mode, the driving scene data and the vehicle state data are analyzed to determine the corresponding target driving mode, including: analyzing the driving scene data and the vehicle state data; when it is determined based on the road condition data that the road condition of the vehicle is good, and the road is a flat road or on a highway or on an urban expressway, and / or when it is determined based on the weather data that the scene of the vehicle is in good weather and the visibility meets the first setting condition, and when the engine speed data meets the first speed condition, and / or the tire state data meets the first state condition, and / or the body posture meets the first posture condition, determine the high-speed two-wheel drive mode as the target driving mode; when any one of the driving scene data and the vehicle state data of the vehicle does not meet the setting condition of the high-speed two-wheel drive mode, determine the low-speed four-wheel drive mode as the target driving mode.

[0067] In this embodiment, the high-speed two-wheel drive mode is determined as the target driving mode of the vehicle only when the driving scene data and the vehicle state data simultaneously meet the setting conditions corresponding to the high-speed two-wheel drive mode. If any one of the driving scene data and the vehicle state data of the vehicle does not meet the setting conditions of the high-speed two-wheel drive mode, the low-speed four-wheel drive mode is determined as the target driving mode.

[0068] Specifically: when the driving scenario data includes road condition data, and / or weather data, the road condition data is analyzed, and when it is determined that the vehicle is currently on a road with good dry or slightly wet road surface, without snow, mud or other adverse conditions, and the road type is a flat road without obvious potholes or rugged sections, or is a highway with a high and stable speed, or a city expressway with a high and stable speed, and / or, the weather data is analyzed, and when it is determined that the vehicle is currently at a good weather location with clear weather or light rain, the road surface is not slippery, and visibility meets the first setting condition (such as visibility reaches 100 meters or more), it is determined that the driving scenario data meets the setting condition corresponding to the high-speed two-wheel drive mode. In the case where the vehicle status data includes engine speed data, and / or tire status data, and / or body posture, the vehicle status data is analyzed, and when it is determined that the engine speed data satisfies the first speed condition (such as the engine is in a medium to high speed range, the power output is stable and efficient, and there is no abnormal jitter or overheating), and / or the tire status data satisfies the first status condition (normal tire pressure, even wear, no damage or aging, moderate tire temperature, good grip), and / or the body posture satisfies the first posture condition (the vehicle runs smoothly, without obvious tilt or bumps, the suspension system works normally, and there is no obvious abnormal noise or fault), it is determined that the vehicle status data meets the set conditions corresponding to the high-speed two-wheel drive mode.

[0069] Based on the same inventive concept, an embodiment of the present application provides a system for switching driving modes, such as Figure 2 As shown, the system 200 includes:

[0070] The signal output module 201 is used to activate the activation signal and output the signal value of the driving mode switching signal according to the received soft switch operation signal, wherein the activation signal is a signal for controlling the vehicle to start executing the driving mode switching process;

[0071] A signal detection module 202, used to detect a signal value of an output drive mode switching signal according to an activation status of an activation signal;
