Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle control, in particular to the field of processing methods for various faults of a rear-drive electronic differential lock control system, and particularly relates to a fault processing method and device, a vehicle and a storage medium. BACKGROUND

[0002] When a vehicle drives into a muddy road, a snowy road or the like, the vehicle is prone to a situation where it cannot normally travel due to slippage of the drive wheels. If an electronic differential lock is configured in the vehicle, the electronic differential lock can lock the differential of the vehicle when the drive wheels of the vehicle slip, so that there is no speed difference between the left and right drive wheels of the vehicle, and at this time the vehicle can rely on the drive wheels that do not slip to restore normal travel of the vehicle.

[0003] With the development of electronic differential lock systems, more and more vehicles begin to be equipped with electronic differential lock systems, but once the electronic differential lock fails during vehicle travel, a traffic accident is likely to occur, which can cause great harm to the vehicle and the user, and therefore fault diagnosis and processing of the electronic differential lock are becoming increasingly important. However, in the related art, only an alarm is performed after detecting that the electronic differential lock fails, and the consideration is not comprehensive enough. SUMMARY

[0004] The present application provides a fault processing method and device, a vehicle and a storage medium to at least solve the problem that in the related art, only an alarm is performed after detecting that the electronic differential lock fails, and the consideration is not comprehensive enough. The technical solutions of the present application are as follows:

[0005] According to a first aspect of the present application, a fault processing method is provided, applied to an electronic differential lock controller of a vehicle; the vehicle further comprises an electronic differential lock and an electronic differential lock switch; the method comprises: obtaining state information; the state information is used to indicate the current running state of the electronic differential lock controller, the electronic differential lock and the electronic differential lock switch; in the case where the state information is used to indicate a first fault, a first fault processing instruction is sent to the vehicle; the first fault processing instruction is used to instruct the vehicle to limit speed, and is used to instruct the vehicle to display first alarm information.

[0006] Compared with the related art, which focuses on the fault detection of the electronic differential lock, the method provided in the present application focuses on the fault processing of the electronic differential lock after detecting the fault of the electronic differential lock. Specifically, when detecting that the fault of the electronic differential lock is more serious, the method provided in the present application sends a first fault processing instruction to the vehicle. The first fault processing instruction not only instructs the vehicle to display warning information to prompt the user, but also limits the speed of the vehicle to ensure the safety of the user during driving, thereby improving the user experience.

[0007] In addition, compared with the related art, which detects the fault of the electronic differential lock only according to the driving state of the vehicle and the on-off state of the electronic differential lock, the method provided in the present application detects the fault information of the electronic differential lock by acquiring the current running states of the electronic differential lock controller, the electronic differential lock and the electronic differential lock switch, so that the fault detection of the electronic differential lock is more comprehensive and accurate.

[0008] In a possible implementation, the first fault includes: double-side short circuit of the electronic differential lock controller, and / or spring return fault of the electronic differential lock; and the first warning information includes: text information displayed on the display of the vehicle to prompt the user to slow down and park on the side, and the differential lock fault lamp on the display of the vehicle continuously flashes.

[0009] According to the above technical means, the present application regards the double-side short circuit of the electronic differential lock controller and / or the spring return fault of the electronic differential lock as the first fault according to the influence degree of the fault of the electronic differential lock on the safety of the vehicle. When the fault occurs, it indicates that the vehicle is in a very dangerous state. Once the vehicle turns at high speed, it is extremely likely to cause a safety problem such as rollover or spin. Therefore, when the first fault of the electronic differential lock is detected, the method provided in the present application displays warning information in time to alert the user to slow down and park on the side, and displays the differential lock fault lamp on the display of the vehicle to continuously flash, thereby avoiding the problem that the user does not know how to process the fault after the fault occurs, ensuring the driving safety of the user and reducing the possibility of traffic accidents.

[0010] In another possible implementation, when the state information does not indicate the first fault, the method further includes: determining whether the state information indicates a second fault; and the second fault includes any one of: single-side fault of the electronic differential lock controller, or other double-side fault of the electronic differential lock controller except double-side short circuit, or switch fault of the electronic differential lock.

[0011] According to the technical means, the method provided by the application divides different faults of the electronic differential lock into different priorities according to the influence of the different faults of the electronic differential lock on the safety of the vehicle. The first fault indicates that the vehicle is in a very dangerous state, and the second fault indicates that the vehicle is in a relatively dangerous state. By classifying different fault types, the processing of the fault can be more accurate, and the driving experience of the user can be improved.

[0012] In another possible implementation, when the state information indicates the first fault or the second fault, the method further includes: when the switch state of the electronic differential lock is open, sending a second fault processing instruction to the vehicle to make the vehicle display second alarm information; the second alarm information includes: the display of the vehicle displays text information prompting the user that the function of the electronic differential lock is exited, and the differential lock fault lamp on the display of the vehicle is always on; when the switch state of the electronic differential lock is closed, sending a third fault processing instruction to the vehicle to make the vehicle display third alarm information; the third alarm information includes: the differential lock fault lamp on the display of the vehicle is always on.

[0013] According to the technical means, the method provided by the application further judges the switch state of the electronic differential lock after detecting that the electronic differential lock fails. If the switch state of the electronic differential lock is open at this time, it indicates that the electronic differential lock is in a locking state, which is an unexpected locking. Therefore, the method provided by the application prompts the user through the second alarm information and informs the user that the function of the electronic differential lock is exited, so as to improve the use perception of the user. If the switch state of the electronic differential lock is closed at this time, it indicates that the electronic differential lock is in an unlocked state, which has a smaller influence on the safety of the vehicle. Therefore, the differential lock fault lamp on the display of the vehicle is always on. The method provided by the application provides different processing methods under different switch states of the electronic differential lock, warns the user, and improves the driving experience and driving perception of the user.

[0014] In another possible implementation, when the state information does not indicate the second fault, the method further includes: when the state information is used to indicate a communication fault of the electronic differential lock controller and the switch state of the electronic differential lock is open, sending a fourth fault processing instruction to the vehicle to make the vehicle display fourth alarm information; the fourth alarm information includes: the display of the vehicle displays text information prompting the user that the function of the electronic differential lock is exited, and the differential lock prompt lamp on the display of the vehicle is turned off after flashing a preset number of times.

[0015] According to the technical means, the method provided in the embodiment of the application classifies the faults of the electronic differential lock and provides different processing methods for different levels of faults. The communication fault is a fault type that has less impact on the driving safety of the vehicle than the second fault. Because the communication fault is not a fault of the hardware system of the electronic differential lock, the communication fault has less impact on the driving process of the vehicle. Therefore, after detecting the communication fault of the electronic differential lock controller, the application detects the switch state of the electronic differential lock and prompts the user with corresponding alarm information. The safety of the vehicle after the fault of the electronic differential lock is ensured, and the user also has a good human-computer interaction experience, improving the driving perception of the user.

[0016] In another possible implementation, the method further includes: in response to the triggering operation of the electronic differential lock button of the vehicle, sending a fifth fault processing instruction to the vehicle to make the vehicle display fifth alarm information; and the fifth alarm information includes: the vehicle display displays text information prompting the user that the electronic differential lock cannot be locked.

[0017] According to the technical means, after detecting the triggering operation of the user on the electronic differential lock button, the method provided in the embodiment of the application displays fifth alarm information to prompt the user. At this time, because the electronic differential lock is in a fault state, the user cannot perform the locking or unlocking operation on the electronic differential lock. Compared with the related art, after detecting the triggering operation of the user, the user cannot perceive whether the triggering operation is successful. The method provided in the application improves the driving experience of the user by prompting the triggering operation of the user.

[0018] According to the second aspect, a fault processing apparatus is provided, which is applied to an electronic differential lock controller of a vehicle. The vehicle further includes an electronic differential lock and an electronic differential lock switch. The fault processing apparatus includes: an acquisition module, configured to acquire state information; the state information is used to indicate the current running state of the electronic differential lock controller, the electronic differential lock, and the electronic differential lock switch; and a sending module, configured to send a first fault processing instruction to the vehicle in a case where the state information indicates a first fault; the first fault processing instruction is used to instruct the vehicle to limit the speed and to instruct the vehicle to display first alarm information.

[0019] In a possible implementation, the first fault includes: double-side short circuit of the electronic differential lock controller and / or spring return fault of the electronic differential lock; and the first alarm information includes: the display of the vehicle displays text information prompting the user to slow down and park on the side, and the differential lock fault lamp on the display of the vehicle flashes continuously.

[0020] In another possible implementation, the fault processing apparatus further includes a determination module; when the state information does not indicate the first fault, the determination module is configured to determine whether the state information indicates a second fault; the second fault includes any one of the following: a single-side fault of the electronic differential lock controller, or a double-side fault of the electronic differential lock controller except for a double-side short circuit, or a switch fault of the electronic differential lock.

[0021] In another possible implementation, when the state information indicates the first fault or the second fault, the sending module is further configured to, when the switch state of the electronic differential lock is open, send a second fault processing instruction to the vehicle to cause the vehicle to display second alarm information; the second alarm information includes: the display of the vehicle displays text information prompting the user to exit the electronic differential lock function, and the differential lock fault lamp on the display of the vehicle is always on; when the switch state of the electronic differential lock is closed, send a third fault processing instruction to the vehicle to cause the vehicle to display third alarm information; the third alarm information includes: the differential lock fault lamp on the display of the vehicle is always on.

[0022] In another possible implementation, when the state information does not indicate the second fault, the sending module is further configured to, when the state information indicates a communication fault of the electronic differential lock controller and the switch state of the electronic differential lock is open, send a fourth fault processing instruction to the vehicle to cause the vehicle to display fourth alarm information; the fourth alarm information includes: the display of the vehicle displays text information prompting the user to exit the electronic differential lock function, and the differential lock prompt lamp on the display of the vehicle is turned off after flashing a preset number of times.

[0023] In another possible implementation, the sending module is further configured to, in response to a triggering operation on the electronic differential lock button of the vehicle, send a fifth fault processing instruction to the vehicle to cause the vehicle to display fifth alarm information; the fifth alarm information includes: the display of the vehicle displays text information prompting the user that the electronic differential lock cannot be locked.

[0024] According to a third aspect of the present application, a vehicle is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, and the processor executes the program to implement the method of the first aspect and any possible implementation thereof.

[0025] According to a fourth aspect of the present application, a computer readable storage medium is provided, when instructions in the computer readable storage medium are executed by a processor of an electronic device, the electronic device can execute the method of the first aspect and any possible implementation thereof.

[0026] Therefore, the above technical features of the present application have the following beneficial effects:

[0027] (1) Compared to related technologies that focus on detecting electronic differential lock malfunctions but do not take further action after detecting a malfunction, potentially leading to traffic accidents, the method provided in this application focuses on handling electronic differential lock malfunctions after they are detected. Specifically, when a serious electronic differential lock malfunction is detected, the method in this application sends a first fault handling command to the vehicle. This command not only instructs the vehicle to display a warning message to the user but also limits the vehicle's speed to ensure user safety during driving and improve the user experience.

[0028] Furthermore, compared to related technologies that only rely on the vehicle's driving status and the electronic differential lock's on / off status to detect electronic differential lock malfunctions, the method provided in this application detects electronic differential lock malfunction information by acquiring the current operating status of the electronic differential lock controller, the electronic differential lock, and the electronic differential lock switch, which makes the detection of electronic differential lock malfunctions more comprehensive and accurate.

[0029] (2) Based on the impact of electronic differential lock malfunctions on vehicle safety, this application considers bilateral short circuits of the electronic differential lock controller and / or electronic differential lock spring return malfunctions as the first malfunctions. When such malfunctions occur, it indicates that the vehicle is in a very dangerous state. If the vehicle turns while traveling at high speed, there is a high probability of rollover or fishtailing. Therefore, the method provided in this application will promptly display warning information when the first malfunction of the electronic differential lock is detected, alerting the user to slow down and pull over, and displaying the differential lock malfunction light continuously flashing on the vehicle's display screen. This avoids the problem of the user not knowing how to handle the malfunction after it occurs, ensuring the user's driving safety and reducing the possibility of traffic accidents.

[0030] (3) The method provided in this application classifies different faults of the electronic differential lock into different priorities based on the degree of impact of different faults on vehicle safety. Among them, the first fault indicates that the vehicle is in a very dangerous state, and the second fault indicates that the vehicle is in a relatively dangerous state. By classifying different fault types into different levels, the handling of faults can be more accurate, thereby improving the user's driving experience.

[0031] (4) The method provided in the embodiment of the present application further judges the switch state of the electronic differential lock after detecting that the electronic differential lock fails, if the switch state of the electronic differential lock is opened at this time, it indicates that the electronic differential lock is in the locked state, which is an unexpected locking, therefore the method provided in the present application prompts the user through the second warning information, informs the user that the function of the electronic differential lock has exited, so as to improve the user's use perception; if the switch state of the electronic differential lock is closed at this time, it indicates that the electronic differential lock is in the unlocked state, at this time, the influence on the safety of the vehicle is small, therefore the differential lock failure lamp on the display of the vehicle can be always on. The method provided in the present application provides different processing methods under different switch states of the electronic differential lock, not only pre-warns the user, but also improves the driving experience and driving perception of the user.

[0032] (5) The method provided in the embodiment of the present application classifies and processes the failure of the electronic differential lock, and provides different processing methods for different levels of failure. Among them, the communication failure is a failure type that has less influence on the driving safety of the vehicle than the second failure. Because the communication failure is not a failure of the hardware system of the electronic differential lock, the communication failure is not serious to the vehicle during driving, therefore after detecting the communication failure of the electronic differential lock controller, the present application detects the switch state of the electronic differential lock and prompts the user with the corresponding warning information, which not only ensures the safety of the vehicle after the electronic differential lock fails, but also brings a good human-computer interaction experience to the user, improving the driving perception of the user.

[0033] (6) The method provided in the embodiment of the present application displays the fifth warning information to prompt the user after detecting the triggering operation of the user on the electronic differential lock button, at this time, because the electronic differential lock is in a failure state, the user cannot lock or unlock the electronic differential lock; compared with the related art, after detecting the triggering operation of the user, the user cannot perceive whether the triggering operation is successful, the method provided in the present application prompts the triggering operation of the user, improving the driving experience of the user.

[0034] It should be noted that the technical effects brought by any one of the implementation manners of the second aspect to the fourth aspect can refer to the technical effects brought by the corresponding implementation manners of the first aspect, which will not be repeated here.

[0035] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0046] In order to make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0047] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following example embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] A fault processing method, device, vehicle and storage medium are described below with reference to the drawings. There are more and more new energy off-road vehicles. In the case that the drive wheels of an off-road vehicle cannot escape from a situation of one side slipping on a muddy road, a snow-covered road or the like, if the vehicle is equipped with a differential lock, the differential lock is used to lock the slipping drive wheels when the drive wheels of the vehicle slip, so that there is no speed difference between the two sides of the drive wheels. At this time, the ground adhesion of the wheels on the other side of the vehicle is higher, and the vehicle can rely on the driving force of the wheels with high adhesion to escape from the situation. The electronic differential lock is very helpful for the vehicle to maintain normal driving on poor roads, but when the vehicle is driving on normal roads, the electronic differential lock fails, for example, when the vehicle is driving at high speed, the electronic differential lock is unexpectedly locked, which will cause the vehicle to spin out of control for rear-wheel drive vehicles, causing harm to users and vehicles. Therefore, fault detection and fault handling of the electronic differential lock are very important, but the electronic differential lock is a relatively new product in the automotive industry, and the related art is not perfect for fault detection of the electronic differential lock, and further processing of the fault after fault detection of the electronic differential lock is not perfect.

[0049] To solve the above problems, the related art proposes a differential lock fault detection method, the core idea of which is to identify the fault of the differential lock through the state of the electronic differential lock switch and the speed difference or longitudinal acceleration of the rear wheels of the vehicle. The judgment of the electronic differential lock failure is completely based on the running state of the vehicle, and the judgment of the electronic differential lock circuit failure is ignored. In addition, after judging that the electronic differential lock function fails, the method only prompts the user through text, sound and icons, and does not further process the vehicle. If the vehicle turns during high-speed driving, the vehicle will have the risk of overturning, causing harm to the driver. Moreover, the fault judgment of the electronic differential lock is not comprehensive, and the fault of the electronic differential lock is not processed in layers according to the fault priority.

[0050] Therefore, to solve the above problems in the related art, the present application provides a fault processing method. Compared with the related art which focuses on fault detection of the electronic differential lock, the method provided by the present application focuses on fault processing of the electronic differential lock after detecting the fault of the electronic differential lock. Specifically, when the fault of the electronic differential lock is detected to be more serious, the method provided by the present application sends a first fault processing instruction to the vehicle. The first fault processing instruction not only instructs the vehicle to display warning information to prompt the user, but also limits the speed of the vehicle to ensure the safety of the user during driving, thereby improving the user experience.

[0051] In addition, compared with the related art, only the running state of the vehicle and the switch state of the electronic differential lock are used to detect the fault of the electronic differential lock, and the method provided in the application detects the fault information of the electronic differential lock by acquiring the current running state of the electronic differential lock controller, the electronic differential lock and the electronic differential lock switch, so that the fault detection of the electronic differential lock is more comprehensive and accurate.

[0052] For ease of understanding, the embodiments of the application are specifically introduced below with reference to the drawings.

[0053] Figure 1 A fault processing system is provided in the embodiments of the application, and the fault processing system comprises an electronic differential lock controller 100, an electronic differential lock switch 200, an electronic differential lock 300, a vehicle display 400 and a vehicle controller 500. The electronic differential lock controller 100 is in communication connection with the electronic differential lock switch 200, the electronic differential lock 300, the vehicle display 400 and the vehicle controller 500 respectively.

[0054] The electronic differential lock controller 100 is configured to control, detect and process the state of the electronic differential lock 300.

[0055] The electronic differential lock 300 is driven by the electronic differential lock controller 100, and the high-side drive controls the current output, and the low-side drive controls the switch, or the high-side drive controls the switch, and the low-side drive controls the current output.

[0056] In some embodiments, the electronic differential lock controller 100 is configured to acquire state information.

[0057] The state information is used to indicate the current running state of the electronic differential lock controller 100, the electronic differential lock switch 200 and the electronic differential lock 300.

[0058] The electronic differential lock controller 100 can analyze the switch signal of the electronic differential lock switch 200.

[0059] In some embodiments, the electronic differential lock controller 100 is further configured to send a first fault processing instruction to the vehicle in the case that the state information indicates a first fault.

[0060] The first fault processing instruction is used to instruct the vehicle controller 500 to limit the speed of the vehicle, and is used to instruct the vehicle display 400 to display first warning information.

[0061] The first fault includes a double-side short circuit of the electronic differential lock controller and / or a spring return fault of the electronic differential lock. The first warning information includes text information displayed on the display of the vehicle to prompt the user to slow down and park on the side, and a differential lock fault lamp on the display of the vehicle that flashes continuously.

[0062] An electronic differential lock switch 200 is configured to send a switch signal to the electronic differential lock 300.

[0063] The electronic differential lock 300 is configured to lock the drive wheel on the slipping side of the vehicle when the drive wheel of the vehicle slips.

[0064] Optionally, the electronic differential lock 300 can be in the form of dog teeth.

[0065] A vehicle display 400 is configured to display the running information of the vehicle.

[0066] In some embodiments, the vehicle display 400 is specifically configured to display first warning information after receiving the first fault handling instruction sent by the electronic differential lock controller 100.

[0067] The vehicle display 400 can be an instrument panel of the vehicle.

[0068] A vehicle controller 500 is configured to monitor the state of the vehicle and send a running state control instruction to control the running state of the vehicle.

[0069] In some embodiments, the vehicle controller 500 is specifically configured to perform speed limiting operation on the vehicle after receiving the first fault handling instruction sent by the electronic differential lock controller 100.

[0070] The vehicle controller 500 can be a vehicle control unit (VCU).

[0071] In some embodiments, the electronic differential lock controller 100 communicates with the vehicle display 400 and the vehicle controller 500 through a controller area network (CAN).

[0072] Figure 2 A fault handling method is provided for the electronic differential lock controller of the vehicle. The vehicle further includes an electronic differential lock and an electronic differential lock switch. The method includes steps S101-S102.

[0073] S101, obtaining state information.

[0074] The state information is used to indicate the current running state of the electronic differential lock controller, the electronic differential lock and the electronic differential lock switch.

[0075] S102, in the case where the state information indicates a first fault, sending a first fault handling instruction to the vehicle.

[0076] The first fault handling instruction is used to instruct the vehicle to limit its speed and to instruct the vehicle to display the first alarm information.

[0077] In some embodiments, the first fault includes: bilateral short circuit of the electronic differential lock controller, and / or, electronic differential lock spring return failure; the first alarm information includes: the vehicle's display showing a text message prompting the user to slow down and pull over, and the differential lock fault light on the vehicle's display continuously flashing.

[0078] Among them, the dual short-circuit fault of the electronic differential lock refers to the combination of faults in the high-side drive and low-side switch control of the electronic differential lock controller.

[0079] Specifically, there are two combinations of bilateral short-circuit faults: one is that the high-side drive of the electronic differential lock controller is short-circuited to ground and the low-side switch control is short-circuited to the power supply; the other is that the high-side drive of the electronic differential lock controller is short-circuited to the power supply and the low-side switch control is short-circuited to ground.

[0080] Understandably, when a bilateral short circuit fault occurs, the electronic differential lock will automatically lock, and there will be no speed difference between the left and right wheels of the rear axle. When the vehicle is traveling at high speed and turning, there is a risk of the vehicle fishtailing or even overturning. Therefore, a bilateral short circuit fault has a significant impact on vehicle safety and is considered a very serious type of fault.

[0081] Among them, the electronic differential lock spring return failure refers to the failure of the electronic differential lock to unlock due to a malfunction in the return spring. The failure risk to the vehicle is the same as that of the aforementioned bilateral short circuit failure of the electronic differential lock controller.

[0082] In some embodiments, such as Figure 3 As shown, after the electronic differential lock controller obtains the status information, it judges the status information. When it is determined that the status information indicates a first fault, the electronic differential lock controller sends a first fault handling command to the VCU. When the VCU receives the first fault handling command, it will intervene in the torque of the vehicle to limit the vehicle speed to a preset speed.

[0083] The first fault handling instruction mentioned above includes the electronic differential lock speed limit request flag 1.

[0084] For example, the preset speed can be 30 kph.

[0085] At the same time, the electronic differential lock controller sends the first fault handling command to the vehicle's display, instructing the vehicle's display to show the text message "Please slow down and pull over immediately", and at the same time instructing the differential lock fault light on the vehicle's display to flash continuously.

[0086] It can be understood that the fault light of the differential lock flashes to indicate that the current fault is more dangerous; the text information prompts the user to slow down and stop on the side immediately, which requires the user to slow down first and then stop on the side to prevent the user from turning when the vehicle is running at high speed, which may cause the risk of vehicle spin or rollover. At the same time, the application limits the speed of the vehicle to ensure that even if the electronic differential lock cannot be unlocked due to failure, the vehicle will not have the risk of spin and rollover when turning at the preset speed.

[0087] It can be understood that the severity and category of the failure of the electronic differential lock system can be classified and prioritized before failure detection and judgment. Among them, the first fault has the highest failure priority and the greatest impact on the vehicle.

[0088] According to the influence of the failure of the electronic differential lock on the safety of the vehicle, the application classifies the double-side short circuit of the electronic differential lock controller and / or the spring return failure of the electronic differential lock as the first fault. When this fault occurs, it indicates that the vehicle is in a very dangerous state. Once the vehicle turns at high speed, it is likely to cause a safety problem such as rollover or spin. Therefore, the method provided by the application displays warning information in time when the first fault of the electronic differential lock is detected, warns the user to slow down and stop on the side, and displays the differential lock fault light flashing on the display of the vehicle, thereby avoiding the problem that the user does not know how to handle the fault after the fault occurs, ensuring the safety of the user and reducing the possibility of traffic accidents.

[0089] In some embodiments, the above step S102 further includes: the electronic differential lock controller drives the electronic differential lock to unlock control.

[0090] It can be understood that since the electronic differential lock has failed, the unlocking control of the above electronic differential lock controller cannot unlock the electronic differential lock, that is, the electronic differential lock controller cannot set the switch state of the electronic differential lock to open, but this step is necessary for safety.

[0091] In some embodiments, before the above step S101, the method further includes: detecting whether the power gear of the vehicle is in an open state.

[0092] Specifically, if the power gear is in an open state, the above steps S101-S102 are executed; if the power gear is not in an open state, the electronic differential lock controller does not execute the above steps S101-S102.

[0093] In some embodiments, as Figure 4As shown, when the state information does not indicate the first fault, the method further includes: S103, determining whether the state information indicates the second fault in a case where the state information does not indicate the first fault.

[0094] In some embodiments, the second fault includes any one of: a single-side fault of the electronic differential lock controller, or a double-side fault of the electronic differential lock controller other than a double-side short circuit, or a switch fault of the electronic differential lock.

[0095] The single-side fault of the electronic differential lock controller means that only one of the high-side drive and the low-side switch control of the electronic differential lock controller has a fault, i.e., one and only one of the following fault types occurs: a high-side drive short circuit to ground, a high-side drive short circuit to power, a high-side drive open circuit, a low-side switch control short circuit to ground, a low-side switch control short circuit to power, and a low-side switch control open circuit.

[0096] The double-side fault of the electronic differential lock controller other than a double-side short circuit means that the combination of the faults of the high-side drive and the low-side switch control of the electronic differential lock controller does not cause the electronic differential lock to be automatically locked, and does not cause a risk of safety impact on the vehicle and personnel.

[0097] The switch fault of the electronic differential lock means a sticking fault of the electronic differential lock switch.

[0098] Optionally, the sticking fault of the electronic differential lock switch includes that the current of the electronic differential lock switch is too large, or the electronic differential lock switch cannot be powered off, etc.

[0099] In some embodiments, when the state information indicates the second fault, the method further includes: the electronic differential lock controller performing drive unlocking control on the electronic differential lock.

[0100] It can be understood that, since the second fault has a low severity, the operation can control the switch state of the electronic differential lock to be in an open state, so as to avoid the electronic differential lock of the vehicle being in an unexpected locked state, and to ensure that the vehicle is in a safe state. According to the influence degree of different faults of the electronic differential lock on the safety of the vehicle, different priorities are divided for different faults of the electronic differential lock. The first fault indicates that the vehicle is in a very dangerous state, and the second fault indicates that the vehicle is in a relatively dangerous state. By grading different fault types, the processing of the faults can be more accurate, and the driving experience of the user can be improved.

[0101] In some embodiments, when the state information indicates the first fault or the second fault, as shown in Figure 5 the method further includes: steps S201-S202.

[0102] S201, in the case that the switch state of the electronic differential lock is open, sending a second fault processing instruction to the vehicle to make the vehicle display second warning information.

[0103] The second warning information includes: the display of the vehicle displays text information prompting the user that the electronic differential lock function is exited, and the differential lock fault lamp on the display of the vehicle is always on.

[0104] In some embodiments, when the state information is used to indicate the first fault or the second fault, the electronic differential lock controller determines whether the switch state of the electronic differential lock at the previous moment is open. When the switch state is open, it indicates that the electronic differential lock is in the locked state at this moment. At this moment, the electronic differential lock controller sends a second fault processing instruction to the display of the vehicle, instructing the display of the vehicle to display the text information "electronic differential lock function exited" on the display according to the second fault processing instruction, and instructing the electronic differential lock fault lamp on the display of the vehicle to be always on.

[0105] It can be understood that after detecting that the electronic differential lock fails, the switch state of the electronic differential lock is also determined. If the switch state of the electronic differential lock is open at this moment, it indicates that the electronic differential lock is in the locked state, which is an unexpected locking. Therefore, the method provided by the present application prompts the user through the second warning information, and informs the user that the function of the electronic differential lock has exited, so as to improve the user's use perception. If the switch state of the electronic differential lock is closed at this moment, it indicates that the electronic differential lock is in the unlocked state, which has little effect on the safety of the vehicle. Therefore, the differential lock fault lamp on the display of the vehicle is always on. The method provided by the present application provides different processing methods under different switch states of the electronic differential lock, pre-warns the user, and also improves the user's driving experience and driving perception.

[0106] S202, in the case that the switch state of the electronic differential lock is closed, sending a third fault processing instruction to the vehicle to make the vehicle display third warning information.

[0107] The third warning information includes: the differential lock fault lamp on the display of the vehicle is always on.

[0108] In some embodiments, when the state information is used to indicate the first fault or the second fault, the electronic differential lock controller determines whether the switch state of the electronic differential lock at the previous moment is open. When the switch state is open, it indicates that the electronic differential lock is in the locked state at this moment. At this moment, the electronic differential lock controller sends a second fault processing instruction to the display of the vehicle, instructing the display of the vehicle to display the text information "electronic differential lock function exited" on the display according to the second fault processing instruction, and instructing the electronic differential lock fault lamp on the display of the vehicle to be always on.

[0109] It can be understood that, since the second fault is controllable, the impact on the user and the vehicle is not serious, and therefore only a text message prompt and a constant-on electronic differential lock fault light are needed.

[0110] In some embodiments, in the case that the state information does not indicate the second fault, the method further comprises: in the case that the state information is used to indicate a communication fault of the electronic lock differential controller, and the switch state of the electronic differential lock is open, sending a fourth fault handling instruction to the vehicle to make the vehicle display fourth warning information.

[0111] In some embodiments, the communication fault comprises: a communication error between some nodes in the CAN communication network, resulting in an abnormal or interrupted problem of data transmission, such as an End-to-End (E2E) fault. Alternatively, in the CAN communication process, after sending data, the receiving node cannot respond or reply in time, resulting in a time interval fault of the sending node considering that the data transmission is abnormal and retransmitting, such as a Timeout fault.

[0112] Among them, the two types of faults are used to indicate that the CAN signal interaction between the controllers in the vehicle is faulty, or the CAN signal loss fault.

[0113] Among them, the fourth warning information comprises: the display of the vehicle displays text information prompting the user to exit the electronic differential lock function, and the differential lock prompt light on the display of the vehicle is extinguished after flashing a preset number of times.

[0114] In some embodiments, before sending the fourth fault handling instruction to the vehicle, the electronic differential lock controller will drive the electronic differential lock to be unlocked.

[0115] It can be understood that, since the communication fault is not a fault of a part of the vehicle, the operation can control the switch state of the electronic differential lock to be open, avoiding the electronic differential lock of the vehicle being in an unexpected locked state, and ensuring that the vehicle is in a safe state.

[0116] It can be understood that, the method provided by the embodiments of the present application classifies and processes the faults of the electronic differential lock, and provides different processing methods for different levels of faults. Among them, the communication fault is a fault type that has less impact on the driving safety of the vehicle than the second fault. Because the communication fault is not a fault of the hardware system of the electronic differential lock, the communication fault is not serious to the vehicle during driving, so after detecting the communication fault of the electronic differential lock controller, the present application detects the switch state of the electronic differential lock and prompts the user with corresponding warning information, which not only ensures the safety of the vehicle when the electronic differential lock fails, but also brings a good human-computer interaction experience to the user, improving the user's driving perception.

[0117] In some embodiments, in the case that the state information is used to indicate a communication failure of the electronic differential lock controller, the electronic differential lock controller detects the switch state of the electronic differential lock, and in the case that the switch state of the electronic differential lock is open, the electronic differential lock controller sends a fourth fault handling instruction to the vehicle, instructing the vehicle to display text information of "differential lock function exit" on the display of the vehicle, and instructing the electronic differential lock prompt light of the display of the vehicle to flash for a preset number of times and then turn off.

[0118] For example, the preset number of times can be 5 times.

[0119] It can be understood that, since the communication failure is not a failure of a part of the vehicle, the probability of recovery from the communication failure is relatively high, and therefore only text information and flashing of the differential lock prompt light are needed to remind the driver, without the need for the failure light of the differential lock to be constantly on or flashing.

[0120] In some embodiments, the method further includes: in response to a triggering operation of an electronic differential lock button of the vehicle, sending a fifth fault handling instruction to the vehicle to cause the vehicle to display fifth warning information.

[0121] The fifth warning information includes: the vehicle display displays text information prompting that the electronic differential lock cannot be locked.

[0122] For example, when the triggering operation of the electronic differential lock button of the vehicle by the user is to request the switch of the electronic differential lock to be open, that is, the user requests the vehicle to be locked, the electronic differential lock controller sends the fifth fault handling instruction to the vehicle, instructing the display of the vehicle to display text information of "cannot be locked".

[0123] It can be understood that, the method provided in the embodiments of the present application displays the fifth warning information to prompt the user after detecting the triggering operation of the electronic differential lock button by the user, and at this time, since the electronic differential lock is in a failure state, the user cannot perform a locking or unlocking operation on the electronic differential lock; compared with the related art in which no prompt is given to the user after detecting the triggering operation of the user, the user cannot perceive whether the triggering operation is successful, the method provided in the present application prompts the triggering operation of the user, thereby improving the driving experience of the user.

[0124] The above is an embodiment of the fault handling method provided in the present application, and the fault handling method is further described below in the form of examples for the convenience of understanding.

[0125] For example, as shown in Figure 6 the flowchart of the fault handling method provided in the present application. Specifically,

[0126] Step a1: detecting whether the power gear of the vehicle is in an open state; if yes, performing step a2; if no, ending the fault handling.

[0127] Step a2, detecting whether the electronic differential lock controller has a double-side short circuit fault or the electronic differential lock switch has a spring return fault; if yes, issuing a first fault processing instruction and executing step a8; if no, executing step a3.

[0128] Step a3, detecting whether the electronic differential lock controller has a single-side fault or other double-side fault; if yes, executing step a8; if no, executing step a4.

[0129] Step a4, detecting whether the electronic differential lock switch has a switch fault; if yes, executing step a8; if no, executing step a5.

[0130] Step a5, detecting whether the electronic differential lock controller has a communication fault; if yes, executing step a6; if no, ending the fault processing.

[0131] Step a6, the electronic differential lock controller executing a drive unlocking control.

[0132] Step a7, detecting whether the switch state of the electronic differential lock at the last time is a closed state; if yes, issuing a fourth fault processing instruction and executing step a11; if no, ending the fault processing.

[0133] Step a8, the electronic differential lock controller executing a drive unlocking control.

[0134] Step a9, detecting whether the switch state of the electronic differential lock at the last time is an open state; if yes, issuing a second fault processing instruction and executing step a11; if no, executing step a10.

[0135] Step a10, detecting whether the switch state of the electronic differential lock at the last time is a closed state; if yes, issuing a third fault processing instruction and executing step a11; if no, ending the fault processing.

[0136] Step a11, detecting whether the user has a trigger operation of opening the electronic differential lock; if yes, issuing a fifth fault processing instruction; if no, ending the fault processing.

[0137] It can be understood that, compared with the related art which focuses on the fault detection of the electronic differential lock, the electronic differential lock is not further processed after the electronic differential lock fails, and the user is prone to traffic accidents during driving. The method provided in the application focuses on the fault processing of the electronic differential lock after detecting the fault of the electronic differential lock. Specifically, when the method provided in the application detects that the fault of the electronic differential lock is more serious, a first fault processing instruction is sent to the vehicle. The first fault processing instruction not only instructs the vehicle to display warning information to prompt the user, but also limits the speed of the vehicle to ensure the safety of the user during driving, thereby improving the user experience.

[0138] In addition, compared with the related art which detects the fault of the electronic differential lock only according to the driving state of the vehicle and the on-off state of the electronic differential lock, the method provided in the application detects the fault information of the electronic differential lock by acquiring the current running state of the electronic differential lock controller, the electronic differential lock and the electronic differential lock switch, so that the fault detection of the electronic differential lock is more comprehensive and accurate.
