Description

Technical Field

[0001] This invention relates to the field of vehicle fault diagnosis, and more specifically, to a method, apparatus, and vehicle for locating vehicle faults. Background Technology

[0002] Vehicle fault diagnosis and location refers to the use of specialized tools and equipment to inspect various aspects of a vehicle, such as the engine, transmission system, and braking system, to determine whether a fault exists and to pinpoint its location. This helps vehicle repair personnel quickly and accurately diagnose problems to ensure the normal operation of the vehicle.

[0003] When a vehicle malfunctions, existing methods typically involve using the instrument cluster malfunction indicator light to detect the fault and using a diagnostic tool to read fault codes to determine the presence and location of the fault. However, these methods have several drawbacks: firstly, the number (or types) of faults detected by the instrument cluster malfunction indicator light are limited, usually only identifying the more obvious and / or serious faults; secondly, reading fault codes requires specialized tools from a 4S dealership. Consequently, existing vehicle fault location methods are inefficient and costly in terms of fault location and detection.

[0004] As the above analysis shows, there is currently no effective solution to the problem of low efficiency and high cost caused by the reliance on instrument panel malfunction indicator lamp feedback and tools provided by automotive service providers for the fault location methods provided by the aforementioned technologies.

[0040] Under the above operating environment, the embodiments of the present invention provide as follows: Figure 2 The method for locating vehicle faults is shown. Figure 2 This is a flowchart of a method for locating vehicle faults according to an embodiment of the present invention, such as... Figure 2 As shown above, Figure 2 The embodiments shown may include at least the following implementation steps, namely, the technical solutions implemented by steps S21 to S24.

[0041] Step S21: In response to the vehicle control data meeting the first condition, control the vehicle to enter the fault location mode, wherein the vehicle control data includes: vehicle speed, motor speed, gear, brake pedal opening and gear shift lever action.

[0042] In the optional technical solution provided in step S21 above, the vehicle control data can be collected by multiple sensors set on the vehicle under the control of the vehicle controller. For example, the gear position sensor is used to collect gear information and gear shift lever action, and the displacement sensor at the brake pedal is used to collect the brake pedal opening. In addition, the vehicle control data can also be directly read based on the vehicle's display device, such as directly reading the vehicle speed, motor speed and other information displayed on the vehicle's instrument panel.

[0043] In the optional technical solution provided in step S21 above, the first condition is used to constrain the vehicle to enter the fault location mode. As an optional implementation, the first condition may include: vehicle speed ≤ 3km / h, motor speed ≤ 80rpm, gear in parking gear (or, electronic parking brake locked), brake pedal opening 0 (i.e., brake pedal not depressed), and shifting the gear lever forward two notches quickly and then backward two notches, ensuring that the duration of each action is ≥ 5s. It should also be noted that the electronic parking brake (EPB) can use the vehicle's electronic control unit and electric drive mechanism to replace the traditional manual brake operation.

[0044] Step S22: When the vehicle is in fault location mode, perform fault identification on the vehicle and obtain fault information.

[0045] In the optional technical solutions provided in step S22 above, the fault information may include, but is not limited to: engine faults (including but not limited to: difficulty starting the engine, increased fuel consumption, unstable idling speed), braking system faults (including but not limited to: brake failure, excessive braking distance), transmission system faults (including but not limited to: transmission jerking, difficulty shifting gears, abnormal noises when driving), vehicle electronic system faults (including but not limited to: black screen or frozen central control screen, no sound from the audio system, air conditioning failure), tire faults (including but not limited to: severe tire wear, tire blowout, air leak), fuel system faults (including but not limited to: fuel leak, water entering the fuel tank), power output faults (including but not limited to: sluggish acceleration, high forward resistance, driving vibration), and other faults (including but not limited to: battery faults, window lift function failure, sunroof opening and closing difficulties).

[0046] Step S23: Based on the fault information and the preset fault table, generate a target fault code, wherein the target fault code includes multiple code bits;

[0047] In the technical solution provided by this invention, as an optional implementation, the invention can display vehicle fault information at the remaining driving range position on the vehicle's dashboard. Under this condition, the aforementioned preset fault table can be a correspondence between the fault information and the remaining driving range position. Specifically, for example, the fault information includes engine faults, braking system faults, transmission system faults, body electronic system faults, tire faults, fuel system faults, power output faults, and other faults. The remaining driving range positions include: 0km, 50km, 100km, 150km, 200km, 250km, 300km, and 350km. The preset fault table can be as shown in Table 1 below.

[0048] Table 1

[0049] Fault Information driving range Engine failure 0km Braking system failure 50km Transmission system failure 100km Vehicle electronic system malfunction 150km Tire failure 200km Fuel system failure 250km Power output failure 300km Other faults 350km

[0050] In the technical solution provided by this invention, each code bit in the aforementioned target fault code can be a one-bit integer. The target fault code can contain multiple fault information, and each fault information can be represented by one or more code bits. Specifically, for example, the target fault code is a seven-bit integer. From left to right, the first to third code bits can be used to represent vehicle speed information, the fourth and fifth code bits can be used to represent throttle opening information, the sixth code bit can be used to represent brake opening information, and the seventh code bit can be used to represent vehicle mode. It should also be noted that the vehicle mode can include, but is not limited to: normal driving mode, charging mode, and fault location mode.

[0051] Step S24: Control the vehicle to display the target fault code.

[0052] The technical solution provided by this invention can make full use of the vehicle's display device to display the target fault code, including but not limited to: displaying the target fault code by utilizing the correspondence between the mileage position in the driving range meter and the fault information, displaying the target fault code by utilizing the correspondence between the engine speed position in the engine tachometer and the fault information, and displaying the target fault code by utilizing the correspondence between the vehicle speed position in the vehicle speed meter and the fault information.

[0053] In this embodiment of the invention, firstly, in response to the vehicle control data meeting a first condition, the vehicle is controlled to enter a fault location mode, wherein the vehicle control data includes: vehicle speed, motor speed, gear position, brake pedal opening and gear shift lever action. Next, while the vehicle is in the fault location mode, the vehicle is fault identified to obtain fault information. Further, based on the fault information and a preset fault table, a target fault code is generated, wherein the target fault code includes multiple code bits. Finally, the vehicle is controlled to display the target fault code.

[0054] It is easy to understand that the above-mentioned method provided by the present invention judges and controls the vehicle to enter the fault location mode based on vehicle control data. After determining that there is a fault in the vehicle, it generates a target fault code based on the fault information and the preset fault table, and displays the target fault code. This achieves the purpose of quickly identifying and locating vehicle faults, thereby improving the efficiency of vehicle fault identification and location and reducing the cost of vehicle fault identification and location. It also solves the technical problem that the fault location methods provided by related technologies rely on instrument fault light feedback and tools provided by the car service provider, resulting in low efficiency and high cost.

[0055] The methods described in the embodiments of the present invention will be further described below.

[0056] In an optional embodiment, in step S21, the first condition includes: the vehicle speed is less than a first threshold; the motor speed is less than a second threshold; the gear is in parking gear; the brake pedal opening is less than a third threshold; the gear shift lever action satisfies the second condition, wherein the second condition is: the gear shift lever first moves to a first position and remains there for at least a first duration, and then moves to a second position and remains there for at least a second duration.

[0057] In the technical solution provided by the present invention, as an optional implementation, the first threshold can be 3 km / h, the second threshold can be 80 rpm, the third threshold can be 1, the first position can be pushing the gear shift lever to move it forward two notches, the second position can be pushing the gear shift lever to move it backward two notches, and both the first duration and the second duration can be 5 seconds. Thus, the first condition can be determined as follows: vehicle speed < 3 km / h, motor speed < 80 rpm, gear in parking gear, brake pedal opening less than 1, the gear shift lever first moves forward two notches and holds the action for at least 5 seconds, then moves backward two notches and holds the action for at least 5 seconds.

[0058] In the above optional embodiments, the technical effect that can be achieved is: by controlling the vehicle to autonomously enter the fault location mode based on the vehicle's own control data, the technical problem of high cost caused by using special equipment such as fault diagnostic instruments and detectors to detect and locate vehicle faults can be avoided, thereby reducing costs and improving the utilization rate of vehicle control data.

[0059] In an optional embodiment, in step S23, generating the target fault code based on the fault information and a preset fault table includes:

[0060] Step S231: Priority analysis is performed on multiple fault parameters corresponding to at least one fault in the fault information to determine at least one parameter to be displayed. The multiple fault parameters include fault name, fault status parameter and fault condition parameter. The fault status parameter is used to characterize whether the current fault has been eliminated. The fault condition parameter is the vehicle parameter under the fault condition corresponding to at least one fault. The fault condition parameter includes vehicle speed, accelerator pedal opening, brake pedal opening, driving mode parameter and assembly status parameter.

[0061] Step S232: Based on the preset fault table, determine at least one parameter fault code corresponding to at least one parameter to be displayed;

[0062] Step S233: Generate a target fault code using at least one parameter fault code.

[0063] As an alternative implementation, assuming the vehicle is currently experiencing sluggish acceleration and brake failure, the various fault parameters corresponding to these two faults can be shown in Table 2 below:

[0064] Table 2

[0065]

[0066] In Table 2 above, a fault status parameter of 1 can be used to indicate that the fault still exists, and correspondingly, a fault status parameter of 0 can be used to indicate that the fault has been eliminated; a driving mode parameter of 1 can be used to indicate that the vehicle is in driving mode, and correspondingly, a driving mode parameter of 2 can be used to indicate that the vehicle is in charging mode, and a driving mode parameter of 3 can be used to indicate that the vehicle is in fault location mode; an assembly status parameter of 0 can be used to indicate that the vehicle assembly is operating abnormally, and correspondingly, an assembly status parameter of 1 can be used to indicate that the vehicle assembly is operating normally.

[0067] In the above optional implementation, it is assumed that the vehicle fault priority is predefined as follows: Level I, Level II, and Level III. Level I can be used to characterize the vehicle fault as a minor fault, which may include, but is not limited to, faults that have little impact on the driver but pose potential risks. Level II can be used to characterize the vehicle fault as a general fault, which may include, but is not limited to, faults that limit the speed or torque of the driving function, high-voltage safety alarm faults, and faults that seriously affect drivability and comfort. Level III can be used to characterize the vehicle fault as a serious fault, which may include, but is not limited to, faults that seriously affect the vehicle's driving function and the vehicle's high-voltage safety. Thus, it can be determined that the priority of the above-mentioned brake failure fault is higher than that of the acceleration sluggish fault.

[0068] In the above optional implementation, further assuming that the preset fault table is a correspondence between fault information and remaining mileage, and assuming that the remaining mileage range of the remaining mileage is 0 to 200 km (resolution of 1 km), the parameter fault codes corresponding to each fault parameter of the above brake failure fault in Table 2 can be as shown in Table 3 below:

[0069] Fault parameters Parameter Fault Codes driving range Speed 030 30km Accelerator pedal opening 20 20km Brake pedal opening 0 0km Driving mode parameters 1 1km

[0070] In the technical solution provided by the present invention, it should also be noted that when displaying the fault code corresponding to the vehicle fault, the parameter fault code corresponding to each fault parameter can be displayed one by one. Thus, the above-mentioned target fault code can be the parameter fault code corresponding to the currently displayed (or the next to be displayed) fault parameter.

[0071] In the above optional embodiments, the technical effects that can be achieved are: defining the priority of vehicle faults, and determining the parameter fault codes of the fault parameters to be displayed according to the preset fault table, thereby making full use of the vehicle's own equipment to display vehicle fault information, improving the utilization rate of vehicle equipment and the convenience of vehicle fault location. At the same time, the priority setting can ensure that serious vehicle faults are displayed first, thereby timely prompting vehicle users (maintenance personnel) to repair faults in a timely manner, reducing user losses, extending the service life of the vehicle, and also improving the user experience.

[0072] In an optional embodiment, in step S24, the fault information includes multiple fault parameters corresponding to multiple faults, the target fault code includes multiple sub-fault codes corresponding to multiple faults, and controlling the vehicle to display the target fault code includes:

[0073] Step S241: Based on multiple fault parameters, perform display priority analysis on multiple faults to determine the display order of multiple sub-fault codes;

[0074] Step S242: Control the vehicle to display multiple sub-fault codes in the display order.

[0075] In the technical solution provided by this invention, it should also be noted that the priorities of multiple fault parameters can be predefined. Therefore, when displaying the fault codes corresponding to vehicle faults, the parameter fault codes corresponding to each fault parameter can be displayed one by one according to their priority. Specifically, in the above optional embodiments, it can be assumed that the priority of the fault parameters is: vehicle speed > accelerator pedal opening > brake pedal opening > driving mode parameters. Therefore, when displaying, the display order of the parameter fault codes can be determined as: 030, 20, 0, 1.

[0076] In the above optional embodiments, the technical effects that can be achieved are: defining the priority of vehicle faults, and determining the parameter fault codes of the fault parameters to be displayed according to the preset fault table, thereby making full use of the vehicle's own equipment to display vehicle fault information, improving the utilization rate of vehicle equipment and the convenience of vehicle fault location. At the same time, the priority setting can ensure that serious vehicle faults are displayed first, thereby timely prompting vehicle users (maintenance personnel) to repair faults in a timely manner, reducing user losses, extending the service life of the vehicle, and also improving the user experience.

[0077] In an optional embodiment, step S242, controlling the vehicle to display multiple sub-fault codes in the order of display includes:

[0078] Step S2421: Based on the display order and gear shift lever action, control the vehicle to display multiple sub-fault codes in pages.

[0079] In the optional solution provided in step S2421 above, the shift lever action can be used to switch the information currently displayed on the display device to the sub-fault code of the current vehicle fault. It can be understood that the shift lever action can be, but is not limited to: when the vehicle is in fault location mode, quickly push the shift lever forward two positions and hold the action for no less than 0.5 seconds before releasing the shift lever.

[0080] In an optional embodiment, in step S2421, controlling the vehicle to display multiple sub-fault codes in pages based on the display order and gear shift lever action includes:

[0081] Step S24211: Based on the display order, determine the current sub-fault code to be displayed from multiple sub-fault codes, and control the target display device corresponding to the vehicle to display the current sub-fault code;

[0082] In step S24212, in response to the shift lever action satisfying the third condition, the target sub-fault code to be switched is determined by using the display order and the current sub-fault code, and the target display device is controlled to switch from displaying the current sub-fault code to displaying the target sub-fault code. The third condition is: the shift lever moves from the default position to the third position and remains there for at least the third duration, and then returns to the default position.

[0083] As an optional implementation, assuming the vehicle's odometer is used to display the vehicle fault, after entering the fault location mode, the odometer first displays the parameter fault code corresponding to the vehicle speed parameter (such as 030 in Table 3 above). When the gear shift lever is quickly pushed forward two notches and held for at least 0.5 seconds before being released, the odometer is controlled to display the parameter fault code corresponding to the accelerator pedal opening (such as 20 in Table 3 above). When the aforementioned gear shift lever action is performed again, the odometer can be controlled to display the parameter fault code corresponding to the brake pedal opening (such as 0 in Table 3 above).

[0084] In the technical solution provided by the present invention, it should also be noted that when it is necessary to view the parameter fault code corresponding to the fault parameter of the previous priority, the display device can be controlled to display the parameter fault code of the fault parameter of the previous priority by executing the shift lever reset action. The shift lever reset action can be, but is not limited to, pressing the parking gear switch for more than 0.5 seconds and then releasing it.

[0085] As another optional implementation, assuming that the vehicle's odometer is used to display the vehicle fault, and the vehicle is in fault location mode, assuming that the fault parameter corresponding to the currently displayed fault code is the brake pedal opening, when the action of pressing the parking switch for more than 0.5 seconds and then releasing it is performed, the odometer can switch to the fault code corresponding to the accelerator pedal opening.

[0086] In the technical solution provided by the present invention, it should also be noted that the display function of the present invention may also include fault name display. Specifically, for example, when the vehicle enters the fault location mode, the target display device can automatically display the fault name. When it is necessary to switch the display function, a switching action based on the gear shift lever can be performed to realize the display function switching. The switching action based on the gear shift lever may be, but is not limited to: quickly pushing the gear shift lever backward two positions and holding the action for a time of not less than 0.5 seconds before releasing the gear shift lever.

[0087] In the above optional embodiments, the technical effects that can be achieved are: displaying vehicle faults based on the gear shift lever action control display device improves the utilization rate of the vehicle gear shift lever, enhances the convenience and efficiency of the method for locating vehicle faults, thereby improving the user experience and reducing the cost of vehicle fault detection and location. In addition, it provides multiple display functions for vehicle faults (including but not limited to the above-mentioned fault name display and fault parameter display), making it convenient for users to select the target display function according to their needs, thereby meeting the diverse needs of users.

[0088] In an optional embodiment, the method for locating vehicle faults further includes:

[0089] Step S25: When the vehicle is in fault location mode, control the vehicle to keep it in park, lock the electronic parking brake, block the accelerator pedal signal, and switch the instrument display mode corresponding to the target display device to fault display mode.

[0090] In the technical solution provided by this invention, it should also be noted that when the vehicle is in fault location mode, and it is necessary to view the current (or historical) faults of the vehicle, the vehicle can be controlled to maintain a parked position, lock the electronic parking brake, and block the accelerator pedal signal, thereby switching the instrument display mode corresponding to the target display device to the fault display mode. It should also be noted that when the resolution of the target display device in instrument display mode is high, its resolution can be adjusted to meet the display requirements of the fault codes. Specifically, for example, if the resolution of the target display device in instrument display mode is 0.1, and since each bit of the fault code is an integer, when the target display device switches from instrument display mode to fault display mode, the resolution of the instrument is adjusted to 1 to meet the display requirements of the fault codes.

[0091] In an optional embodiment, the method for locating vehicle faults further includes:

[0092] Step S26: When the vehicle is in fault location mode, in response to the second condition being met by the shift lever action, control the vehicle to exit fault location mode.

[0093] In the technical solution provided by this invention, it should also be noted that when the vehicle is currently in fault location mode, when it is necessary to exit the fault location mode, a corresponding gear shift lever action can be performed. This gear shift lever action can be, but is not limited to: controlling the gear shift lever to push forward two increments and maintaining this action for a duration of not less than 5 seconds, then controlling the gear shift lever to push backward two increments and ensuring that this action lasts for a duration of not less than 5 seconds. At this time, the vehicle exits the fault location mode. Simultaneously, the vehicle unshields the display device displaying the gear shift failure reminder, unshields the accelerator pedal signal, and can use the display device to prompt the vehicle user in text form that the vehicle has exited the fault location mode. The vehicle fault code display device (such as the aforementioned odometer) is controlled to switch to odometer numbers, and the odometer resolution is restored.
