[0029] Figure 2 This is a flowchart of a fault information output method for an integrated braking control system according to an embodiment of this application, such as... Figure 2 As shown, the method includes the following steps:
[0030] Step S202: Detect the network status of the integrated braking control system;
[0031] Step S204: If the network status indicates a network fault, collect the power supply voltage of the integrated braking control system.
[0032] Step S206: Determine the target voltage range where the power supply voltage is located from multiple preset voltage ranges;
[0033] Step S208: Determine whether to output fault information corresponding to the network fault, at least based on the target voltage range.
[0034] Through the above steps, the following can be achieved: detecting the network status of the integrated braking control system; when the network status indicates a network fault, acquiring the power supply voltage of the integrated braking control system; determining the target voltage range of the power supply voltage from multiple preset voltage ranges; and determining whether to output fault information corresponding to the network fault based at least on the target voltage range. By detecting the system's power supply voltage while detecting the system's network status, and determining accurate fault information based on the target voltage range of the power supply voltage, the accuracy of fault information is improved, thereby achieving the technical effect of improving fault diagnosis efficiency. This solves the technical problem of low fault diagnosis efficiency caused by low accuracy of output fault information.
[0035] Steps S202 to S208 are described in detail below through examples.
[0036] In some embodiments of this application, the specific steps for determining whether to output fault information corresponding to the network fault based at least on the target voltage range include: when the target voltage range is a normal preset voltage range among the plurality of preset voltage ranges, determining to output fault information corresponding to the network fault, wherein the fault information corresponding to the network fault is a first type of diagnostic fault code; and when the target voltage range is an abnormal preset voltage range other than the normal preset voltage range among the plurality of preset voltage ranges, determining not to output fault information corresponding to the network fault.
[0037] As is understandable, diagnostic fault codes (DTCs) are a standardized system used to diagnose and report vehicle malfunctions. When a vehicle's integrated braking control system detects a fault, it generates a specific code indicating the type and location of the fault. These codes can be read and interpreted to help vehicle repair personnel accurately locate and repair the fault. DTCs typically consist of a string of numbers and letters; for example, P0300 indicates random multi-cylinder misfires in the engine.
[0038] Optionally, after determining not to output the fault information corresponding to the network fault, the fault information corresponding to the power supply voltage fault is output, and the fault information corresponding to the power supply voltage fault is a second type of diagnostic fault code.
[0039] In practical application scenarios, after determining not to output the fault information corresponding to the network fault, the second type of diagnostic fault code is directly output instead of the first type of diagnostic fault code, which also reduces the occupation of internal system storage space.
[0040] In some embodiments of this application, whether the target voltage range is the abnormal preset voltage range is determined in the following ways, for example: when the target voltage range is a first range or a second range, the target voltage range is determined to be the abnormal preset voltage range, wherein the minimum value of the first range is greater than the first preset voltage value, the maximum value of the second range is less than the second preset voltage value, and the first preset voltage value is greater than the second preset voltage value.
[0041] If the time taken for the target voltage range to change from the first range to the third range does not exceed the first time range, it is determined that the fault information corresponding to the network fault will not be output, wherein the maximum value of the third range is not greater than the third preset voltage value.
[0042] Optionally, if the time for the target voltage range to change from the second range to the fourth range does not exceed the second time range, it is determined that the fault information corresponding to the network fault will not be output, wherein the minimum value of the fourth range is not less than the fourth preset voltage value, and the third preset voltage value is greater than the fourth preset voltage value.
[0043] Specifically, such as Figure 3As shown, taking the first interval as greater than the first preset voltage value of 16V, the second interval as less than the second preset voltage value of 9V, the third interval as not greater than the third preset voltage value of 15.5V, and the fourth interval as not less than 9.5V as an example, when the power supply voltage is detected to be greater than 16V (trigger condition 1) or the time for the power supply voltage to recover from greater than 16V to no greater than 15.5V does not exceed the first duration of 550ms (trigger condition 2), it is determined that the fault information corresponding to the network fault will not be output, and the fault information will be marked as Net-Undervoltage to indicate abnormal power supply voltage, and the second type of diagnostic fault code will be output.
[0044] Similarly, such as Figure 3 As shown, if the power supply voltage is detected to be less than 9V (trigger condition 4) or the time for the power supply voltage to recover from less than 9V to not less than 9.5V does not exceed the second duration of 550ms (trigger condition 5), it is determined that the fault information corresponding to the network fault will not be output, and the fault information will be marked as Net-Undervoltage to indicate abnormal power supply voltage, and the second type of diagnostic fault code will be output.
[0045] It should be noted that condition 3 is triggered when a network status indicator shows a network failure.
[0046] Optionally, after outputting the second type of diagnostic fault code, the method further includes: if the time for the target voltage range to change from the first range to the third range exceeds a first time duration, marking the output second type of diagnostic fault code as a repaired historical fault.
[0047] If the target voltage range changes from the second range to the fourth range for more than a second duration, the output second type of diagnostic fault code will be marked as a repaired historical fault.
[0048] In one alternative approach, the fault can be indicated as fixed by re-outputting the third type of diagnostic fault code.
[0049] It is understandable that the first duration and the second duration can be the same or different.
[0050] It should be noted that if the target voltage range of the power supply voltage is greater than the second preset voltage value and not greater than the third preset voltage value, the power supply voltage is determined to be normal. If a network fault is detected, the fault information corresponding to the network fault will be directly output.
[0051] The method provided in this application monitors both network faults and whether the power supply voltage exceeds the normal range. If the fault reporting conditions are not met, monitoring continues. When both conditions are met simultaneously, fault information corresponding to network low voltage or network overvoltage faults is reported instead of the fault information corresponding to the network fault itself. This effectively avoids reporting many network faults caused by low or overvoltage. Directly outputting voltage fault information facilitates faster fault location and can also record faults where power supply anomalies exist. Furthermore, it avoids the presence of network fault information caused by low or overvoltage, which could hinder the analysis of other fault causes.
[0052] The integrated brake control system fault information output method provided in this application embodiment is also applied to an integrated brake control system fault information output device provided in this application embodiment, such as... Figure 4 As shown, it includes: a detection module 40 for detecting the network status of the integrated braking control system; a data acquisition module 42 for acquiring the power supply voltage of the integrated braking control system when the network status indicates a network fault; a determination module 44 for determining the target voltage range of the power supply voltage from multiple preset voltage ranges; and an output module 46 for determining whether to output fault information corresponding to the network fault, at least based on the target voltage range.
[0053] The output module 46 includes a first information submodule and a second information submodule. The first information submodule is used to determine the fault information corresponding to the network fault when the target voltage range is a normal preset voltage range among the plurality of preset voltage ranges, and the fault information corresponding to the network fault is a first type of diagnostic fault code; and to determine not to output the fault information corresponding to the network fault when the target voltage range is an abnormal preset voltage range other than the normal preset voltage range among the plurality of preset voltage ranges.
[0054] The second information submodule is used to output the fault information corresponding to the power supply voltage fault after determining that the fault information corresponding to the network fault is not output. The fault information corresponding to the power supply voltage fault is a second type of diagnostic fault code.
[0055] The determining module 44 includes: a determining submodule, which is used to determine the target voltage range as the abnormal preset voltage range when the target voltage range is a first range or a second range, wherein the minimum value of the first range is greater than a first preset voltage value, the maximum value of the second range is less than a second preset voltage value, and the first preset voltage value is greater than the second preset voltage value.
[0056] The determination submodule further includes: a first determination unit and a second determination unit. The first determination unit is used to determine that the fault information corresponding to the network fault will not be output when the time for the target voltage range to change from the first range to the third range does not exceed a first time. The maximum value of the third range is not greater than a third preset voltage value.
[0057] The second determining unit is used to determine not to output the fault information corresponding to the network fault when the time for the target voltage range to change from the second range to the fourth range does not exceed the second time range, wherein the minimum value of the fourth range is not less than the fourth preset voltage value, and the third preset voltage value is greater than the fourth preset voltage value.
[0058] The output module 46 includes an output submodule, which is used to mark the output second type of diagnostic fault code as a repaired historical diagnostic fault code if the time for the target voltage range to change from the first range to the third range exceeds a first time after the second type of diagnostic fault code is output.
