[0045] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] In the first aspect, an embodiment of the present invention provides a method for repairing calibration failure.

[0048] In order to more clearly show the method for repairing calibration failure provided by the embodiments of the present application, first, the application scenario of the method for repairing calibration failure provided by the embodiments of the present application will be introduced.

[0049] The method for repairing calibration failure provided by the embodiments of the present application is applied to the height sensor, which is a core component of the air suspension system. Due to assembly errors, it is necessary to calibrate the height sensor on the detection line after the vehicle is off the production line to eliminate the assembly errors of the height sensor. However, there are many prerequisite conditions that need to be met when calibrating the height sensor. As long as one of them is not met, the calibration of the height sensor will fail. After the calibration of the height sensor fails, the repair personnel need to quickly locate and know the reason for the calibration failure in order to quickly carry out the repair.

[0050] In one embodiment, referring to Figure 1 , Figure 1 is a schematic flow chart of an embodiment of the method for repairing calibration failure of the present invention. As Figure 1 shown, the method for repairing calibration failure includes:

[0051] Step S10: When the air suspension detects a calibration failure of the height sensor, identify the cause of the calibration failure.

[0052] In this embodiment, referring to Figure 2 , Figure 2 is a schematic diagram of the air suspension system architecture of an embodiment of the calibration failure repair method of the present invention. As Figure 2 shown, the calibration process of the height sensor is detected by the air suspension control unit. When a calibration failure of the height sensor is detected, the cause of the calibration failure is automatically identified through the software algorithm in the air suspension control unit.

[0053] Step S20: Transmit the cause of the calibration failure to the calibration device.

[0054] In this embodiment, after the air suspension control unit identifies the cause of the calibration failure, it transmits the cause of the calibration failure to the calibration device. The calibration device displays the cause of the calibration failure, and the calibration personnel learn the cause of the calibration failure of the height sensor and stop the calibration process of the height sensor.

[0055] Step S30: The calibration device obtains the vehicle identification code and transmits the vehicle identification code and the cause of the calibration failure to the repair device.

[0056] In this embodiment, the calibration device obtains the vehicle identification code for calibrating the height sensor, such as the vehicle VIN code, and further transmits the vehicle identification code and the cause of the calibration failure to the repair device at the repair station of the inspection line.

[0057] Step S40: The repair device matches the repair method according to the cause of the calibration failure.

[0058] In this embodiment, after receiving the cause of the calibration failure, the repair device can query the relationship data table of the cause of the calibration failure and the repair method stored in the repair device system to match and obtain the corresponding repair method. Among them, the relationship data table of the cause of the calibration failure and the repair method can be constructed in advance and stored in the repair device system. The relationship data table of the cause of the calibration failure and the repair method is shown in Table 1. Table 1 is the relationship data table of the cause of the calibration failure and the repair method.

[0060]

[0061]

[0062] Step S50: When the terminal scans the vehicle identification code, the repair device displays the cause of the calibration failure and the repair method.

[0063] In this embodiment, when the repair personnel use the terminal device to scan the vehicle identification code, the repair device displays the calibration failure reason and the repair method, so that the repair personnel can quickly know the calibration failure reason and can quickly perform the repair according to the repair method.

[0064] In this embodiment, the air suspension control unit detects the calibration process of the height sensor. When it is detected that the calibration of the height sensor fails, the software algorithm in the air suspension control unit automatically identifies the calibration failure reason, transmits the calibration failure reason to the calibration device and the repair station device, and matches the repair method. When the repair personnel use the terminal device to scan the vehicle identification code, the repair device displays the calibration failure reason and the repair method, so that the repair personnel can quickly know the calibration failure reason and can quickly perform the repair according to the repair method, thus avoiding the need to check various reasons during traditional repair, saving a large amount of time, reducing the labor cost, and improving the repair efficiency.

[0065] Further, in one embodiment, before step S10, it includes:

[0066] Calibrate the height sensor according to the calibration process.

[0067] In this embodiment, referring to Figure 3 , Figure 3 is a schematic diagram of the calibration process of an embodiment of the calibration failure repair method of the present invention. As shown in Figure 3 , the calibration process may include initial condition detection, four-wheel wheel center to wheel arch height detection, body lift and lower detection controlled by the air suspension controller, and calibration parameter range detection, etc. Calibrate the height sensor in sequence according to the calibration process. If a corresponding calibration process is successfully completed, the calibration of this calibration process is successful and proceeds to the next calibration process; otherwise, the calibration of this calibration process fails, and further identify the calibration failure reason. After all the calibration processes are successfully completed, the overall calibration of the height sensor is completed and the calibration ends.

[0068] Further, in one embodiment, referring to Figure 4 , Figure 4 is Figure 1 a detailed process schematic diagram of step S10. As shown in Figure 4 , step S10 includes:

[0069] Step S101, when the air suspension detects that the current calibration process of the height sensor fails, detect whether the calibration conditions required for the current calibration process are met;

[0070] Step S102, if not, use the unmet calibration conditions as the calibration failure reason.

[0071] In this embodiment, the calibration process may include initial condition detection, four-wheel center-to-wheel-arch height detection, body lift and lower detection controlled by an air suspension controller, calibration parameter range detection, etc. Among them, each calibration process includes one or more calibration conditions that need to be met. Each calibration condition is sequentially detected to determine whether it is met. If a certain calibration condition is not met, the unmet calibration condition is taken as the reason for calibration failure. For example, in the calibration process of initial condition detection, the calibration conditions to be met include: no fault in the air suspension system, all four doors or the tailgate of the vehicle are closed, the maintenance mode of the air suspension system is not activated, the vehicle is not charging, the transportation mode of the air suspension system is not activated, the I / O manual control of the air suspension system has been exited, and the vehicle is normally powered on; in the calibration process of four-wheel center-to-wheel-arch height detection, the calibration conditions to be met include: the input height value of the detection line calibration equipment is within the normal range and the input height value of the detection line calibration equipment is valid; in the calibration process of body lift and lower detection controlled by the air suspension controller, the calibration conditions to be met include: the air storage tank pressure is sufficient or the air pump is not overheated, the body is adjusted to within ±5 mm within 5 adjustments, the height sensor is normally installed, and there are no other problems; in the calibration process of calibration parameter range detection, the calibration conditions to be met include: the height sensor is normally installed. Therefore, based on the calibration conditions that need to be met in the current calibration process with calibration failure, each calibration condition is sequentially detected and judged through a software algorithm, and the reason for calibration failure can be automatically identified.

[0072] Further, in one embodiment, step S10 further includes:

[0073] Lifting the body to a first preset height and lowering the body to a second preset height through the air suspension;

[0074] If the body height cannot be lifted or lowered within a preset time period, it is determined that the detection result is that the height sensor calibration fails, and the mechanical failure is taken as the reason for calibration failure.

[0075] In this embodiment, the calibration process of the height sensor may further include lifting the body to a first preset height and lowering the body to a second preset height through the air suspension. The first preset height is, for example, +15 mm, the second preset height is, for example, ±5 mm, and the preset time period is, for example, 20 seconds. If the body height cannot be lifted or lowered within the preset time period, it is determined that the detection result is that the height sensor calibration fails, and the mechanical failure is taken as the reason for calibration failure.

[0076] Further, in one embodiment, after the step of if the body height cannot be lifted or lowered within the preset time period, it is determined that the detection result is that the height sensor calibration fails, and the mechanical failure is taken as the reason for calibration failure, it includes:

[0077] Adjust the air suspension through a diagnostic instrument to inflate and deflate the air spring;

[0078] If the vehicle body cannot be raised and the value of the height sensor remains unchanged, then blockage of the air pipeline is taken as the cause of calibration failure;

[0079] If after the vehicle body is raised, the rate of descent of the vehicle body is greater than the preset descent rate, and the rate of change of the value of the height sensor is greater than the preset rate of change, then leakage of the air pipeline is taken as the cause of calibration failure;

[0080] If after the vehicle body is raised, the vehicle body cannot descend and the value of the height sensor remains unchanged, then abnormal assembly of the air pipeline is taken as the cause of calibration failure;

[0081] If the vehicle body can be raised and lowered, but the value of the height sensor remains unchanged, then breakage of the height sensor bracket is taken as the cause of calibration failure.

[0082] In this embodiment, different from the automatic identification of the cause of calibration failure by the air suspension control unit through software algorithms, after the calibration of the height sensor fails and it is determined that the cause of calibration failure is a mechanical fault, manual means can be used to adjust the air suspension through a diagnostic instrument to inflate and deflate the air spring, and further judge in combination with the specific situation to clarify the specific type of mechanical fault. The specific types of mechanical faults include blockage of the air pipeline, leakage of the air pipeline, abnormal assembly of the air pipeline (such as the air pipeline is not installed properly), and breakage of the height sensor bracket. After adjusting the air suspension through a diagnostic instrument to inflate and deflate the air spring, if the vehicle body cannot be raised and the value of the height sensor remains unchanged, it means that the air pipeline is blocked, then blockage of the air pipeline is taken as the cause of calibration failure; if after the vehicle body is raised, the rate of descent of the vehicle body is greater than the preset descent rate, that is, the vehicle body descends at a faster rate due to air leakage in the air pipeline, and the rate of change of the value of the height sensor is greater than the preset rate of change, that is, the value of the height sensor changes at a faster rate, it means that the air pipeline leaks, then leakage of the air pipeline is taken as the cause of calibration failure; if after the vehicle body is raised, the vehicle body cannot descend and the value of the height sensor remains unchanged, it means that the air pipeline is abnormally assembled, such as the air pipeline is not installed properly, then abnormal assembly of the air pipeline is taken as the cause of calibration failure; if the vehicle body can be raised and lowered, but the value of the height sensor remains unchanged, it means that the height sensor bracket is broken, then breakage of the height sensor bracket is taken as the cause of calibration failure.

[0083] Further, in one embodiment, step S20 includes:

[0084] Transmit the cause of calibration failure to the calibration device through the UDS diagnostic protocol.

[0085] In this embodiment, UDS (Unified Diagnostic Services) is a standardized criterion for diagnostic services. For example, what instructions should be sent to the controller to read fault codes and what instructions should be sent to read data streams. Through the UDS diagnostic protocol, the reasons for calibration failures can be transmitted to the calibration device more safely and standardly.

[0086] Secondly, an embodiment of the present invention further provides a calibration failure repair device.

[0099] Further, in an embodiment, the identification module 10 is further configured to:

[0100] Control the vehicle body to rise to a first preset height and lower to a second preset height through the air suspension;

[0101] If the vehicle body height cannot be increased or decreased within a preset duration, it is determined that the detection result is a failure in calibrating the height sensor, and the mechanical failure is taken as the reason for the calibration failure.

[0102] Further, in one embodiment, the calibration failure repair device further includes a mechanical failure identification module for:

[0103] Adjust the air suspension through a diagnostic instrument to inflate and deflate the air spring;

[0104] If the vehicle body cannot be raised and the height sensor value remains unchanged, the air pipeline blockage is taken as the reason for the calibration failure;

[0105] If after the vehicle body is raised, the rate of descent of the vehicle body is greater than the preset descent rate and the rate of change of the height sensor value is greater than the preset rate of change, the air pipeline leakage is taken as the reason for the calibration failure;

[0106] If after the vehicle body is raised, the vehicle body cannot descend and the height sensor value remains unchanged, the abnormal assembly of the air pipeline is taken as the reason for the calibration failure;

[0107] If the vehicle body can be raised and lowered, but the height sensor value remains unchanged, the fracture of the height sensor bracket is taken as the reason for the calibration failure.
