Description

Technical Field

[0001] The embodiments of the present invention relate to the field of vehicle technology, and specifically to a self-test method, device, vehicle and storage medium for a braking system. Background Art

[0002] The hydraulic self-check function (HSC) is a process for checking the integrity of the pressure-building and pressure-maintaining functions of the hydraulic system in a vehicle, and is an important means of ensuring the availability of the hydraulic system.

[0003] In the existing related technologies, the braking is automatically performed through the integrated brake control module system after the vehicle is powered off, which results in the user being unable to perceive the availability of the braking system in the vehicle in a timely manner. Summary of the invention

[0004] In view of the above problems, an embodiment of the present invention provides a self-checking method, device, vehicle and storage medium of a braking system, which are used to solve the problem in the prior art that a user cannot timely perceive the availability of a braking system in a vehicle.

[0005] According to one aspect of an embodiment of the present invention, a self-test method for a brake system is provided, the method comprising:

[0006] In response to a user triggering a self-check instruction of a braking system in a vehicle, obtaining status information of the vehicle;

[0007] When it is detected that the state information satisfies a preset self-checking condition, a self-checking operation of the brake system is performed, wherein the self-checking condition is determined based on the working condition of the brake system that the vehicle complies with in the self-checking scenario;

[0008] Feedback the execution result corresponding to the self-check operation to the user.

[0009] According to another aspect of an embodiment of the present invention, there is provided a self-test device for a brake system, comprising:

[0010] An acquisition module, configured to acquire status information of the vehicle in response to a user triggering a self-check instruction of a braking system in the vehicle;

[0011] A first processing module, configured to execute a self-check operation of the brake system when it is detected that the state information satisfies a preset self-check condition, wherein the self-check condition is determined based on a working condition of the brake system that meets the vehicle under a self-check scenario;

[0012] The second processing module is used to feed back the execution result corresponding to the self-check operation to the user.

[0013] According to another aspect of the embodiment of the present invention, a vehicle is provided, comprising: a processor, a memory, a communication interface and a communication bus, wherein the processor, the memory and the communication interface communicate with each other through the communication bus;

[0014] The memory is used to store at least one executable instruction, and the executable instruction enables the processor to execute the operation of the self-test method of the braking system as described above.

[0015] According to another aspect of an embodiment of the present invention, a computer-readable storage medium is provided, wherein at least one executable instruction is stored in the storage medium. When the executable instruction is executed on a self-inspection device of a vehicle / brake system, the self-inspection device of the vehicle / brake system performs operations such as the self-inspection method of the brake system described above.

[0016] The embodiment of the present invention can obtain the vehicle's status information in response to the user triggering the self-check instruction of the brake system in the vehicle through the self-check method, device, vehicle and storage medium of the brake system, and execute the self-check operation of the brake system when it is detected that the status information meets the preset self-check conditions.

[0026] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0027] The hydraulic self-test function is a process that verifies the integrity of the vehicle's hydraulic system's pressure-building and pressure-maintaining functions. It is an important means of ensuring the availability of the hydraulic system.

[0028] Currently, all vehicles using the integrated brake control module system have intelligent assisted driving functions. If you want to enter the intelligent assisted driving mode, you need to use the hydraulic self-test function to check whether the integrated brake control module system can build pressure, whether there is leakage in the pipeline, and whether there are impurities and air in the pipeline. This ensures that the system can build and maintain pressure normally, and ensures that it can respond to the braking torque requests of the power system and intelligent assisted driving systems.

[0029] If the self-test does not start or fails midway, after a certain number of times, the system will report an expired self-test result failure, resulting in failure to enter the intelligent assisted driving mode.

[0030] However, many hydraulic self-test functions are automatically performed by the integrated brake control module system 5-10 minutes after power is turned off or on. This automatic hydraulic self-test generally has many prerequisites, such as: the vehicle must continue to be above a certain speed before the self-test, no auxiliary functions are activated, the electronic caliper is not working, and the vehicle has no abnormal power loss. If these conditions are not met, the HSC self-test will not start, and the system cannot determine its availability. The hydraulic self-test function is also easily interrupted by some routines, such as remote power on and off via Bluetooth, stepping on the brake pedal, and pulling up and releasing the handbrake. These will cause the HSC self-test to be interrupted or fail, and the system cannot determine its availability. The system's automatic self-test has a long waiting time and cannot quickly determine whether the hydraulic system is normal.

[0031] Based on the above technical problems, the technical conception of the present invention is as follows: a manual self-inspection method can be set. When the user needs a self-inspection, the self-inspection can be turned on through hardware, touch, etc. After turning it on, the vehicle can determine whether the self-inspection conditions are met. If not, feedback is given to the user. If it is met, the self-inspection operation of the braking system is entered, and the user can perceive the result in real time after obtaining it, avoiding the existing vehicles relying solely on automatic self-inspection after the system is powered on or off.

[0032] Figure 1 FIG. 2 shows a schematic diagram of the principle of the self-checking method of the brake system provided by the present invention. Figure 1 As shown, the principle schematic diagram includes: redundant brake module, wheel speed sensor, electronic caliper, integrated brake control unit (IBCU), intelligent driving assistance controller, central control screen, vehicle power control unit, and instrument.

[0033] In one possible implementation, the instrument displays the available status of the intelligent driving assistance controller. When it is unavailable, the user clicks the self-test control of the braking system in the central control screen to detect whether the IBCU is faulty. If there is no fault, the status information transmitted by sensors such as the wheel speed sensor, electronic caliper, and vehicle power control unit is obtained. After determining that the status information meets the self-test conditions, the IBCU performs a self-test operation.

[0034] Among them, the self-test operation can be that the central control screen sends a pressure build-up request to the IBCU and the redundant braking module, and the IBCU and the redundant braking module build up pressure and feed back the self-test results to the central control screen and the instrument.

[0035] The technical solution of the present invention is described in detail below through specific embodiments. The executor of the present invention is a vehicle, specifically a controller in the vehicle, such as a central control screen or an IBCU (if it is an IBCU, the details of the solution can be adjusted according to actual conditions, and the principle is similar).

[0036] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0037] Figure 2 FIG. 1 is a flow chart showing a first embodiment of a self-checking method for a braking system provided by the present invention, the method being executed by a vehicle. Figure 2 As shown, the method comprises the following steps:

[0038] Step 21, in response to the user triggering a self-check instruction of the braking system in the vehicle, obtaining the vehicle status information;

[0039] In this step, before performing a self-check on the vehicle's brake system, it is necessary to first obtain the vehicle's status information to determine whether the current vehicle can perform a self-check.

[0040] Optionally, the vehicle status information may be obtained based on a controller area network (CAN) bus, where the vehicle controller obtains the information from various corresponding sensors.

[0041] In a possible implementation, the vehicle status information may include: whether the vehicle is stationary, whether the gear of the vehicle is in the parking gear, whether the electronic caliper of the vehicle is in the tightened state, and whether the brake pedal of the vehicle is in the released state.

[0042] Optionally, before step 21, it is also possible to detect whether the intelligent driving assistance system prompt interface is available. When it is not available, perform subsequent implementation.

[0043] Step 22: When it is detected that the state information meets the preset self-checking condition, a self-checking operation of the brake system is performed;

[0044] Among them, the self-test conditions are determined based on the working conditions that the vehicle meets under the braking system in the self-test scenario.

[0045] In this step, after the vehicle status information is obtained, the vehicle status information is determined to determine whether it satisfies the operating conditions that the vehicle complies with in the self-check scenario of the braking system.

[0046] Optionally, the self-test conditions include: the vehicle's gear is in the parking gear, the vehicle is stationary, the vehicle's electronic caliper is in a tightened state, and the vehicle's brake pedal is in a released state.

[0047] In one possible implementation, based on the status information, when it is determined that the vehicle's gear is in the parking gear, the vehicle is in a stationary state, the vehicle's electronic caliper is in a tightened state, and the vehicle's brake pedal is in a released state, the status information is considered to meet the preset self-test conditions, thereby executing a self-test operation of the braking system.

[0048] Optionally, when it is detected that the status information does not satisfy the self-test condition, prompt information corresponding to the self-test condition is displayed, and the prompt information is used to assist the user in controlling the vehicle so that the status information of the vehicle satisfies the self-test condition.

[0049] In a possible implementation, when there is any item in the status information that does not meet the self-test conditions, such as the vehicle's gear is not in P gear, the prompt message may be "Please shift to P gear"; if the vehicle is in a non-stationary state, the prompt message may be "Please keep the vehicle stationary"; if the vehicle's electronic caliper is not in a clamped state, the prompt message may be "Please pull up the electronic parking brake (Electronic Parking Brake, EPB)"; if the vehicle's brake pedal is in a pressed state, the prompt message may be "Please release the brake pedal."

[0050] Afterwards, when the status information meets the self-check condition, the self-check operation of the braking system may be allowed to be performed.

[0051] Optionally, the self-check operation may be implemented as follows:

[0052] Step 1: Send a hydraulic self-test request to the integrated brake control unit of the vehicle so that the integrated brake control unit performs a self-test operation;

[0053] In this implementation, when the above self-test conditions are met, the central control screen sends a hydraulic self-test request to the integrated brake control unit. When the integrated brake control unit receives the "HSC self-test request status HSC req = 0x1 = active", it starts to build pressure.

[0054] Step 2: Receive a self-test result corresponding to the self-test operation sent by the integrated brake control unit.

[0055] In this implementation, after the integrated brake control unit completes the self-checking operation, a self-checking result corresponding to the self-checking operation is sent to the controller.

[0056] In a possible implementation, if no self-test result is fed back, the central control screen periodically sends "HSC self-test request status HSC req = 0x0 = no request, and the central control screen receives HSC result = 0x0 = fail, and the instrument prompts "HSC failed, please check IBCU".

[0057] In another possible implementation, when the BCU receives the "HSC self-test request status HSC req=0x1=active", it starts to build pressure. After the HSC self-test and pressure building succeed, HSC result=0x1=success is sent. After the HSC self-test and pressure building fails, HSC result=0x0=fail is sent.

[0058] Step 23: Feedback the execution result corresponding to the self-check operation to the user.

[0059] In this step, after the execution result is obtained, feedback is given to the user so that the user is aware of the status of the braking system.

[0060] Optionally, when the braking system is normal and the self-check is completed, the intelligent driving assistance system prompt interface displays that it is available.

[0061] In a possible implementation, the execution result is displayed on the central control screen, such as "the brake system is in normal state"; and if the pressure is successfully built up, the self-test success result is sent to the intelligent assisted driving controller, and the intelligent driving controller cancels the fault status display, that is, the intelligent driving assistance system prompts that the interface is available.

[0062] The self-check method of the braking system provided in the embodiment of the present invention obtains the status information of the vehicle by responding to the self-check instruction of the braking system in the vehicle triggered by the user, and executes the self-check operation of the braking system when it is detected that the status information meets the preset self-check condition. The self-check condition is determined based on the working condition of the vehicle in the self-check scenario of the braking system, and then the execution result corresponding to the self-check operation is fed back to the user. In this technical solution, when responding to the corresponding instruction of the self-check of the braking system issued by the user, the status information of the vehicle is used to determine whether the self-check condition is met, and the self-check is automatically performed when it is met, so that the availability of the braking system can be quickly determined without waiting for the vehicle to completely land to perform the self-check.

[0063] Based on the above embodiments, Figure 3 FIG. 2 is a flow chart showing a second embodiment of a self-checking method for a braking system provided by the present invention, the method being executed by a vehicle. Figure 3 As shown, before step 21, the following possible implementations may be performed:

[0064] Step 31, detecting status information of a plurality of power systems associated with the braking system;

[0065] In this step, the multiple power systems associated with the braking system may be an anti-lock braking system (ABS), an electronic brake force distribution system (EBD), and a traction control system (TCS).

[0066] In this implementation, the status information may be whether the IBCU has an ABS / EBD / TCS function failure, or whether the ABS / EBD / TCS fault light on the instrument panel is on.

[0067] Step 32: When the status information of the plurality of power systems does not indicate the existence of a fault, it is determined that the self-checking function of the braking system is in an available state.

[0068] In this step, when the status information of any of the above power systems indicates that a fault exists, it can be considered that self-checking cannot be performed, that is, the self-checking function of the braking system is in an unavailable state.

[0069] In one possible implementation, a soft switch for turning on / off the self-test function is provided in the vehicle (i.e., one of the icon controls described below, or a button, etc.). When the power is on, the central control screen determines whether the IBCU has the above-mentioned power system fault. If any fault exists, the self-test function of the braking system is in an unavailable state, and the icon of the soft switch is grayed out and cannot be operated. If no fault exists, the self-test function of the braking system is in an available state, and the icon of the soft switch is highlighted, allowing operations in response to the user triggering the self-test instruction of the braking system in the vehicle.

[0070] It should be understood that when the intelligent driving assistance system prompts that the interface is available, it cannot provide user-triggered self-test operations to ensure the safety of the vehicle. That is, when the intelligent driving assistance system prompts that the interface is unavailable, the user can choose to manually click the soft switch in the central control screen to perform a manual self-test to check the availability of the hydraulic system; if the above self-test conditions are not met, the soft switch in the large screen will be grayed out and prompt to check the IBCU system fault. If the icon of the soft switch is highlighted, you can click to perform a hydraulic self-test. If the conditions are met, click the self-test soft switch, and the central control screen sends a self-test request to the integrated braking module. After receiving the request, the integrated braking module builds pressure to the agreed pressure within the preset time. If the pressure is successfully built, the self-test success result is sent to the intelligent assisted driving controller. The intelligent driving controller cancels the fault status display.

[0071] The self-checking method of the brake system provided in the embodiment of the present invention determines that the self-checking function of the brake system is in an available state by detecting the status information of multiple power systems associated with the brake system, when the status information of the multiple power systems does not indicate the existence of a fault. In this technical solution, the self-checking operation can be started only when it is ensured that the multiple power systems associated with the brake system are fault-free, so as to avoid the potential safety hazards of the vehicle after direct startup.

[0072] Based on the above embodiments, Figure 4 FIG. 2 is a flow chart showing a third embodiment of a self-checking method for a braking system provided by the present invention, the method being executed by a vehicle. Figure 4 As shown, step 21 may be implemented as follows:

[0073] Step 41, in response to a preset operation of the user in the vehicle, turning on the self-check function and triggering a self-check instruction;

[0074] In this step, based on the pre-set hardware or software settings, the self-test instruction can be triggered in a variety of ways.

[0075] Optionally, the preset operation includes: triggering a first control of a self-check function in the vehicle;

[0076] Correspondingly, the first control includes: an icon control set in a display unit of the vehicle, or a physical unit set in the vehicle.

[0077] In a possible implementation, an icon control, such as the soft switch described above, may be set in the central control screen of the vehicle. When the soft switch is in an available state, the user clicks it to trigger it.

[0078] A physical unit may also be set in the vehicle, such as a physical button, which is triggered after the user clicks it; for example, an existing physical unit may be used to continuously press the P gear button 10 times, continuously click the Electronic Stability Control (ESC) / Auto Vehicle Hold (AVH) / Hill Descent Control (HDC) switch 10 times, etc.;

[0079] It is also possible to start the HSC self-test via the diagnostic command.

[0080] In a possible implementation, when the self-test command is triggered, the central control screen prompts "HST self-test is about to start, please release the brake pedal, keep the vehicle stationary and shift into P gear. If you need to execute, please click Continue". After clicking Continue, 3 frames are sent to send "HSC self-test request status HSC req = 0x1 = active.

[0081] Step 42: Obtain vehicle status information according to the self-check instruction.

[0082] In this step, after receiving the self-check instruction, the controller obtains status information from each corresponding sensor and the like.

[0083] The self-check method of the brake system provided in the embodiment of the present invention responds to the preset operation of the user in the vehicle, turns on the self-check function, triggers the self-check instruction, and then obtains the vehicle status information according to the self-check instruction. In this technical solution, the self-check function is triggered by the user, so that the preparation work of the vehicle self-check and the subsequent self-check are realized, which enables the user to more quickly perceive whether the hydraulic system is normal.

[0084] Based on the above embodiments, Figure 5 FIG. 4 is a flow chart showing a fourth embodiment of a self-checking method for a braking system provided by the present invention, the method being executed by a vehicle. Figure 5 As shown, combined Figure 1 The following Table 1 describes an implementation of the present invention:

[0085] Step 1: Determine whether the instrument prompt intelligent driving interface is available; if so, proceed to step 7; if not, proceed to step 2;

[0086] Step 2: The user triggers the HSC self-test button on the central control screen;

[0087] Step 3: Check if the IBCU is faulty. If so, gray out the self-check button and proceed to step 7. The central control screen will display a text message "Please check the IBCU".

[0088] Step 4: Check whether the self-test conditions are met; if so, proceed to step 5; if not, proceed as follows:

[0089] That is, if the vehicle is not in P gear, the user is prompted to shift into P gear; if the vehicle is not stationary, the user is prompted to keep the vehicle stationary; if the caliper is not tightened, the user is prompted to pull up the caliper; if the brake pedal is depressed, the user is prompted to release the pedal;

[0090] Step 5: IBCU executes to determine whether the check is successful; if so, proceed to step 6; if not, the central control screen will display a text message "Please check IBCU", and proceed to step 7;

[0091] Step 6: The central control screen prompts that the self-test is successful and the intelligent driving interface is available;

[0092] Step 7. End.

[0093] Among them, the HSC self-test work process table is shown in Table 1 below:

[0094] Table 1:

[0096]

[0097]

[0098] Compared with the prior art, the self-checking method of the brake system provided by the embodiment of the present invention has the following advantages:

[0099] Beneficial effects:

[0100] 1. Many hydraulic self-check functions in the prior art are automatically performed by the integrated brake control module system after power-off or power-on. Such automatic hydraulic self-check has many prerequisites. Often, the HSC self-check will be interrupted or failed due to the failure of the conditions. The system cannot determine the availability and will fail to enter the intelligent assisted driving mode. And there will be no prompt for which conditions are not met and the HSC is not executed or fails to execute.

[0101] 2. Manually start the HSC hydraulic self-test by pressing the manual button, and the response conditions will be prompted before starting, so that users can avoid them in advance. At the same time, if the conditions are not met, it will also prompt which conditions are not met, thereby increasing the success rate of the self-test.

[0102] Figure 6 A structural schematic diagram of an embodiment of a self-test device for a brake system provided by the present invention is shown.

[0103] like Figure 6 As shown, the device comprises:

[0104] An acquisition module 61, configured to acquire vehicle status information in response to a user triggering a self-check instruction of a braking system in the vehicle;

[0105] A first processing module 62 is used to perform a self-check operation of the brake system when it is detected that the state information meets a preset self-check condition, where the self-check condition is determined based on the working condition of the brake system that the vehicle meets in the self-check scenario;

[0106] The second processing module 63 is used to feed back the execution result corresponding to the self-check operation to the user.

[0107] In one or more embodiments, before obtaining the vehicle status information in response to the user triggering the self-check instruction of the braking system in the vehicle, the first processing module 62 is further used to:

[0108] detecting status information of a plurality of power systems associated with a braking system;

[0109] When the status information of the plurality of power systems does not indicate the existence of a fault, it is determined that the self-checking function of the braking system is in an available state.

[0110] In one or more embodiments, the acquisition module 61 is specifically configured to:

[0111] In response to a preset operation of the user in the vehicle, a self-check function is turned on and a self-check instruction is triggered;

[0112] According to the self-check instructions, obtain the vehicle status information.

[0113] In one or more embodiments, the preset operation includes: triggering a first control of a self-check function in the vehicle;

[0114] The first control includes: an icon control set in a display unit of the vehicle, or a physical unit set in the vehicle.

[0115] In one or more embodiments, the first processing module 62 is further configured to:

[0116] When it is detected that the status information does not meet the self-check condition, prompt information corresponding to the self-check condition is displayed, and the prompt information is used to assist the user in controlling the vehicle so that the status information of the vehicle meets the self-check condition.

[0117] In one or more embodiments, the first processing module 62 performs a self-check operation of the braking system, specifically for:

[0118] Sending a hydraulic self-test request to an integrated brake control unit of the vehicle so that the integrated brake control unit performs a self-test operation;

[0119] Receive a self-test result corresponding to the self-test operation sent by the integrated brake control unit.

[0120] In one or more embodiments, the self-test conditions include:

[0121] The vehicle's gear is in the parking gear, the vehicle is stationary, the vehicle's electronic caliper is in a tightened state, and the vehicle's brake pedal is in a released state.

[0122] It should be noted that it should be understood that the division of the various modules of the above device is only a division of logical functions. In actual implementation, all or part of them can be integrated into one physical entity, or they can be physically separated. And these modules can all be implemented in the form of software called by processing elements. They can also be implemented in the form of hardware. Some modules can also be implemented in the form of software called by processing elements, and some modules can be implemented in the form of hardware. In addition, all or part of these modules can be integrated together or implemented independently. The processing element here can be an integrated circuit with signal processing capabilities. In the implementation process, each step of the above method or each module above can be completed by an integrated logic circuit of hardware in the processor element or instructions in the form of software.

[0123] From the above, it can be seen that the self-inspection device of the braking system provided in the embodiment of the present invention can respond to the corresponding instruction of the self-inspection of the braking system issued by the user, and use the status information of the vehicle to determine whether the self-inspection conditions are met, and automatically perform self-inspection when the conditions are met. The availability of the braking system can be quickly determined without waiting for the vehicle to completely land to perform self-inspection.

[0124] Figure 7 A schematic structural diagram of an embodiment of a vehicle of the present invention is shown, and the specific embodiment of the present invention does not limit the specific implementation of the vehicle.

[0125] like Figure 7 As shown, the vehicle may include: a processor (processor) 702 , a communications interface (CommunicationsInterface) 704 , a memory (memory) 706 , and a communication bus 708 .

[0126] The processor 702, the communication interface 704, and the memory 706 communicate with each other via a communication bus 708. The communication interface 704 is used to communicate with other devices such as a client or other server network elements. The processor 702 is used to execute a program 710, which can specifically execute the relevant steps in the above-mentioned embodiment of the self-test method for a braking system.

[0127] Specifically, the program 710 may include program code including computer executable instructions.

[0128] The processor 702 may be a central processing unit (CPU), or an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiment of the present invention. The one or more processors included in the vehicle may be processors of the same type, such as one or more CPUs. They may also be processors of different types, such as one or more CPUs and one or more ASICs.

[0129] The memory 706 is used to store the program 710. The memory 706 may include a high-speed RAM memory, and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory.

[0130] Program 710 may be specifically called by processor 702 to enable the vehicle to perform the following operations:

[0131] In response to a user triggering a self-check instruction of a braking system in a vehicle, obtaining status information of the vehicle;

[0132] When it is detected that the state information satisfies a preset self-checking condition, a self-checking operation of the brake system is performed, wherein the self-checking condition is determined based on the working condition of the brake system that the vehicle complies with in the self-checking scenario;

[0133] Feedback the execution result corresponding to the self-check operation to the user.

[0134] In one or more embodiments, before obtaining the status information of the vehicle in response to the user triggering the self-check instruction of the braking system in the vehicle, the method further includes:
