Technical Field

[0001] This application relates to the field of vehicles, and more specifically, to a method, apparatus, processor, and electronic device for testing abnormal noises in vehicles. Background Technology

[0002] Currently, when a vehicle accelerates on a bumpy road, the wheel speed often fluctuates significantly due to the road surface bumps, causing the vehicle's powertrain transmission system to shake. When the frequency of the wheel speed fluctuations couples with the modal frequency of the powertrain transmission system, the powertrain transmission system resonates, causing an impact at the location of the suspension tie rod and producing abnormal noise.

[0003] However, if the impact between the powertrain drive system and the suspension tie rod is severe, it can cause the housing in the powertrain drive system to break or the suspension tie rod to break, resulting in a technical problem of low safety when the vehicle accelerates on bumpy roads.

[0004] There is currently no effective solution to the technical problem of low safety when vehicles accelerate on bumpy roads. Summary of the Invention

[0005] This invention provides a method, apparatus, processor, and electronic device for testing abnormal noises in vehicles, in order to at least address the technical problem of low safety when vehicles accelerate on bumpy roads.

[0006] According to one aspect of the present invention, a method for testing abnormal noises in a vehicle is provided. The method includes: detecting the road environment in which the vehicle is in motion; adjusting the current transmission torque of the vehicle to obtain a target transmission torque in response to the road environment being a bumpy road surface environment, wherein the current transmission torque is the torque output by the vehicle's transmission system, and the target transmission torque is used to limit the current vibration amplitude of the transmission system; determining the current force on the vehicle's suspension device based on the target transmission torque, wherein the current force is used to represent the force borne by the suspension device between the transmission system and the vehicle's wheels; and performing an abnormal noise test on the vehicle based on the current force to obtain an abnormal noise test result, wherein the abnormal noise test result is used to indicate whether the vehicle has successfully responded to an abnormal noise event, and the abnormal noise event is used to indicate that an abnormal noise is generated by an impact between the transmission system and the suspension device in a bumpy road surface environment. Since the embodiments of the present invention determine the road environment in which the vehicle is located, and if the road environment is a bumpy road environment, the current transmission torque of the vehicle is adjusted to obtain the target transmission torque, and the current force determined by the target transmission torque is used to conduct an abnormal noise test on the vehicle, the abnormal noise test results can be obtained. This achieves the purpose of testing whether the vehicle can cope with abnormal noise, thereby realizing the technical effect of improving the safety of the vehicle when accelerating on a bumpy road.

[0007] Optionally, in response to a bumpy road environment, the current transmission torque of the vehicle is adjusted to obtain a target transmission torque. This includes: in response to a bumpy road environment, determining a target adjustment strategy for the current transmission torque based on the current wheel speed, wherein the current speed is related to the current power of the transmission system, and the target adjustment strategy represents the method of adjusting the current transmission torque; and adjusting the current transmission torque according to the target adjustment strategy to obtain the target transmission torque. Since the target transmission torque can be obtained by adjusting the current transmission torque of the vehicle based on the determined target adjustment strategy, the purpose of adjusting the current transmission torque of the vehicle is achieved, thereby realizing the technical effect of improving the flexibility of the vehicle's transmission torque.

Since the abnormal noise test result obtained from performing an abnormal noise test on the vehicle will also be different if the target relationship between the current applied force and the preset applied force range is different, the purpose of determining whether the vehicle has successfully responded to the abnormal noise event is achieved, thereby realizing the technical effect of improving the accuracy of abnormal noise testing on the vehicle.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] According to an embodiment of the present invention, a method for testing abnormal noises in a vehicle is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] Figure 1 This is a flowchart of a vehicle abnormal noise testing method according to an embodiment of the present invention, such as... Figure 1 As shown, the method may include the following steps:

[0032] Step S101: Detect the road environment in which the vehicle is in motion.

[0033] In the technical solution provided by step S101 of the present invention, the road environment can be different types of road surface environments. For example, different types of road surface environments may include: bumpy road surface environment, asphalt road surface environment, dirt road surface environment and racetrack road surface environment, etc., which are only examples and are not specifically limited here.

[0034] In this embodiment, the road environment in which the vehicle is in motion is detected. Optionally, this embodiment can acquire driving data and image data of the vehicle in motion. The driving data may include vehicle speed, acceleration, and braking data, etc., and the image data can be used to represent the vehicle's surrounding environment. Environmental recognition is performed on the driving data to obtain an environmental recognition result, which can be used to represent a first initial road environment matching the driving data. From the image data, a second initial road environment included in the surrounding environment can be determined, and the environmental similarity between the first and second initial road environments can be determined. Based on the environmental similarity between the first and second initial road environments, the road environment in which the vehicle is in motion can be detected.

[0035] Optionally, the road environment in which the vehicle is in motion can be detected based on the environmental similarity between the first initial road environment and the second initial road environment. For example, if the environmental similarity is greater than or equal to a preset environmental similarity, the first initial road environment and the second initial road environment are merged into the same road environment, thereby detecting the road environment in which the vehicle is in motion.

[0036] Optionally, based on the aforementioned environmental similarity, the road environment in which the vehicle is in motion can be detected. For example, if the aforementioned environmental similarity is less than a preset environmental similarity, the aforementioned first initial road environment and the aforementioned second initial road environment are fused to obtain a fused road environment. The obtained fused road environment is then determined as the road environment in which the vehicle is in motion, thereby achieving the purpose of detecting the road environment in which the vehicle is in motion.

[0037] It should be noted that the above-mentioned preset environment similarity can be set according to the frequency of occurrence of the historical road environment in which the vehicle is located. For example, if the historical road environment in which the vehicle is located is a bumpy road environment, and the frequency of occurrence of this bumpy road environment is 7 times / cycle, then the above-mentioned preset environment similarity can be 95%. This value is only for illustrative purposes and is not a specific limitation.

[0038] Step S102: In response to the road environment being a bumpy road surface, the current transmission torque of the vehicle is adjusted to obtain the target transmission torque, wherein the current transmission torque is the torque output by the vehicle's transmission system, and the target transmission torque is used to limit the current vibration amplitude of the transmission system.

[0039] In the technical solution provided by step S102 of the present invention, the current transmission torque can be the torque output by the vehicle's transmission system. For example, if the transmission system is a powertrain transmission system (referred to as powertrain), then the current transmission torque can be the powertrain output torque.

[0040] In this embodiment, the target transmission torque can be used to limit the current vibration amplitude of the transmission system. For example, if the transmission system is a powertrain transmission system, the target transmission torque can be used to limit the current vibration amplitude of the powertrain transmission system.

[0041] In this embodiment, after detecting the road environment in which the vehicle is in motion, the current transmission torque of the vehicle is adjusted in response to the road environment being a bumpy road surface to obtain a target transmission torque. Optionally, based on the detected road environment, this embodiment matches the detected road environment with different types of road surface environments. If the detected road environment is matched to a bumpy road surface environment, the current transmission torque of the vehicle is adjusted according to the target adjustment strategy for the current transmission torque to obtain the target transmission torque, thereby achieving the purpose of obtaining a torque that limits the current vibration amplitude of the transmission system.

[0042] Optionally, if the detected road environment is matched to a road environment other than a bumpy road environment, the road environment is switched to a bumpy road environment. If the switched road environment is a bumpy road environment, the current transmission torque of the vehicle is adjusted according to the target adjustment strategy for the current transmission torque to obtain the target transmission torque, thereby achieving the purpose of obtaining the torque that limits the current vibration amplitude of the transmission system.

[0043] Step S103: Based on the target transmission torque, determine the current force on the vehicle's suspension device, wherein the current force is used to represent the force exerted on the suspension device by the transmission system and the vehicle's wheels.

[0044] In the technical solution provided by step S103 of the present invention, the aforementioned current force can be used to represent the force borne by the suspension device between the transmission system and the vehicle wheels. For example, if the suspension device is a suspension tie rod, then the aforementioned current force can be the force borne by the suspension tie rod between the transmission system and the vehicle wheels.

[0045] In this embodiment, in response to a bumpy road environment, the current transmission torque of the vehicle is adjusted to obtain a target transmission torque. Based on the target transmission torque, the current force on the vehicle's suspension is determined. Optionally, based on obtaining the target transmission torque, this embodiment can adjust the vibration amplitude of the transmission system from the current vibration amplitude to the target vibration amplitude; if the vibration amplitude of the transmission system has been adjusted to the target vibration amplitude, the current force on the vehicle's suspension can be determined.

[0046] Step S104: Based on the current force, perform an abnormal noise test on the vehicle to obtain the abnormal noise test result. The abnormal noise test result is used to indicate whether the vehicle has successfully dealt with the abnormal noise event. The abnormal noise event is used to indicate that the abnormal noise is generated by the collision between the transmission system and the suspension device in a bumpy road environment.

[0047] In the technical solution provided by step S104 of the present invention, the above-mentioned abnormal noise test result can be used to indicate whether the vehicle has successfully responded to the abnormal noise event. For example, the above-mentioned abnormal noise test result can indicate that the vehicle has successfully responded to the abnormal noise event, or it can indicate that the vehicle has failed to respond to the abnormal noise event. This is only an example and is not specifically limited.

[0048] In this embodiment, the aforementioned abnormal noise event can be used to indicate an abnormal noise caused by an impact between the transmission system and the suspension device on a bumpy road surface. For example, if the transmission system is a powertrain transmission system and the suspension device is a suspension tie rod, then the aforementioned abnormal noise event can be used to indicate an abnormal noise caused by an impact between the powertrain transmission system and the suspension tie rod on a bumpy road surface.

[0049] In this embodiment, after determining the current force on the vehicle's suspension system based on the target transmission torque, an abnormal noise test is performed on the vehicle based on the current force to obtain the abnormal noise test results. Optionally, this embodiment can determine a target relationship between the current force and a preset force range based on the determined current force. By performing an abnormal noise test on the vehicle according to the target relationship, abnormal noise test results can be obtained, thereby achieving the purpose of testing whether the vehicle can cope with abnormal noises.

[0050] It should be noted that the aforementioned preset force range can be determined based on the type of suspension device. For example, if the type of suspension device is a coil spring, the aforementioned preset force range can be the force range corresponding to the type of coil spring; if the type of suspension device is not a coil spring, the aforementioned preset force range can be the force range corresponding to the type of non-coil spring. This is only an example and is not a specific limitation.

[0051] In steps S101 to S104 of this application, when testing for abnormal noises in a vehicle, the road environment in which the vehicle is driving can be detected. In response to the detected road environment being a bumpy surface, the current transmission torque of the vehicle is adjusted to obtain a target transmission torque. Based on the adjusted target transmission torque, the current force on the vehicle's suspension system can be determined. Based on the determined current force, an abnormal noise test is performed on the vehicle, yielding the abnormal noise test result. Because this embodiment of the invention, based on determining the road environment in which the vehicle is located, adjusts the vehicle's current transmission torque to obtain a target transmission torque if the road environment is a bumpy surface, and performs an abnormal noise test on the vehicle based on the current force determined by the target transmission torque, an abnormal noise test result can be obtained. This achieves the purpose of testing whether the vehicle can cope with abnormal noises, thereby realizing the technical effect of improving the safety of the vehicle when accelerating on bumpy roads.

[0052] The method described below for adjusting the vehicle's current transmission torque to obtain a target transmission torque in response to a bumpy road environment, as described above in this embodiment, will be further described.

[0053] As an optional embodiment, step S102, in response to the road environment being a bumpy road surface environment, adjusts the current transmission torque of the vehicle to obtain a target transmission torque, including: in response to the road environment being a bumpy road surface environment, determining a target adjustment strategy for the current transmission torque based on the current rotational speed of the wheels, wherein the current rotational speed is associated with the current power of the transmission system, and the target adjustment strategy is used to represent the way to adjust the current transmission torque; adjusting the current transmission torque according to the target adjustment strategy to obtain the target transmission torque.

[0054] In this embodiment, the current rotational speed can be used to represent the current rotational speed of the wheel, and the current rotational speed can be associated with the current power of the transmission system.

[0055] In this embodiment, the aforementioned target adjustment strategy can be used to represent the way to adjust the current transmission torque.

[0056] In this embodiment, after detecting the road environment in which the vehicle is in motion, and in response to the road environment being a bumpy road surface, a target adjustment strategy for the current transmission torque is determined based on the current wheel rotation speed. Optionally, this embodiment matches the detected road environment with different types of road surface environments based on the detected road environment. If the detected road environment is matched to a bumpy road surface environment, then a target adjustment strategy for the current transmission torque can be determined based on the current wheel rotation speed.

[0057] In this embodiment, in response to a bumpy road environment, after determining a target adjustment strategy for the current transmission torque based on the current wheel speed, the current transmission torque is adjusted according to the target adjustment strategy to obtain the target transmission torque. Optionally, this embodiment, based on the determined target adjustment strategy, adjusts the current transmission torque according to the determined target adjustment strategy to obtain the target transmission torque. Since the target transmission torque can be obtained by adjusting the vehicle's current transmission torque based on the determined target adjustment strategy, the purpose of adjusting the vehicle's current transmission torque is achieved, thereby realizing the technical effect of improving the flexibility of the vehicle's transmission torque.

[0058] The method described below for determining a target adjustment strategy for the current transmission torque based on the current rotational speed of the wheel, as described in this embodiment, will be further described below.

[0059] As an optional embodiment, a target adjustment strategy for the current transmission torque is determined based on the current rotational speed of the wheel, including: obtaining the previous rotational speed of the current rotational speed; determining the rotational speed fluctuation range between the current rotational speed and the previous rotational speed; and determining the target adjustment strategy corresponding to the rotational speed fluctuation range.

[0060] In this embodiment, the aforementioned rotational speed fluctuation amplitude can be used to represent the amount of wheel speed fluctuation between the current rotational speed and the previous rotational speed.

[0061] In this embodiment, the aforementioned target adjustment strategy can correspond one-to-one with the aforementioned speed fluctuation range. For example, if the speed fluctuation range is 200 rpm, the aforementioned target adjustment strategy can be a first target adjustment strategy, which can be used to indicate a 30% reduction in the current transmission torque; if the speed fluctuation range is 500 rpm, the aforementioned target adjustment strategy can be a second target adjustment strategy, which can be used to indicate a 50% reduction in the current transmission torque; if the speed fluctuation range is 800 rpm, the aforementioned target adjustment strategy can be a third target adjustment strategy, which can be used to indicate an 80% reduction in the current transmission torque. The values ​​here are only illustrative examples and are not specifically limited.

[0062] In this embodiment, after detecting the road environment in which the vehicle is in motion, the previous rotational speed is obtained; the rotational speed fluctuation range between the current and previous rotational speeds is determined; and a target adjustment strategy corresponding to the rotational speed fluctuation range is determined. Optionally, this embodiment, based on the detected road environment, obtains the current rotational speed of the wheels and the previous rotational speed; the difference between the current and previous rotational speeds is calculated to obtain the rotational speed fluctuation range between the two speeds; then, according to the target adjustment strategies corresponding to different rotational speed fluctuation ranges, the target adjustment strategy corresponding to the aforementioned rotational speed fluctuation range can be found. Since the target adjustment strategy corresponds to the rotational speed fluctuation range, the purpose of determining the target adjustment strategy corresponding to the rotational speed fluctuation range is achieved, thereby realizing the technical effect of improving the accuracy of the target adjustment strategy.

[0063] Optionally, if the aforementioned speed fluctuation range is 210 rpm, then according to the target adjustment strategies corresponding to different speed fluctuation ranges, a first target adjustment strategy corresponding to the aforementioned speed fluctuation range of 210 rpm can be found, and the found first target adjustment strategy is determined as the target adjustment strategy corresponding to the speed fluctuation range; if the aforementioned speed fluctuation range is 520 rpm, then according to the target adjustment strategies corresponding to different speed fluctuation ranges, a second target adjustment strategy corresponding to the aforementioned speed fluctuation range of 520 rpm can be found, and the found second target adjustment strategy is determined as the target adjustment strategy corresponding to the speed fluctuation range; if the aforementioned speed fluctuation range is 830 rpm, then according to the target adjustment strategies corresponding to different speed fluctuation ranges, a third target adjustment strategy corresponding to the aforementioned speed fluctuation range of 830 rpm can be found, and the found third target adjustment strategy is determined as the target adjustment strategy corresponding to the speed fluctuation range. The values ​​here are only illustrative examples and are not specifically limited.

[0064] The method for determining the current force on the vehicle's suspension device based on the target transmission torque described in this embodiment will be further described below.

[0065] As an optional embodiment, step S103, determining the current force on the vehicle's suspension device based on the target transmission torque, includes: adjusting the vibration amplitude of the transmission system from the current vibration amplitude to the target vibration amplitude according to the target transmission torque; and determining the current force under the target vibration amplitude.

[0066] In this embodiment, in response to a bumpy road environment, the vehicle's current transmission torque is adjusted to obtain a target transmission torque. Then, according to the target transmission torque, the vibration amplitude of the transmission system is adjusted from the current vibration amplitude to the target vibration amplitude. Optionally, in this embodiment, based on obtaining the target transmission torque, the vibration amplitude of the transmission system can be adjusted from the current vibration amplitude to the target vibration amplitude according to the aforementioned target transmission torque.

[0067] In this embodiment, after adjusting the vibration amplitude of the transmission system from the current vibration amplitude to the target vibration amplitude according to the target transmission torque, the current force is determined at the target vibration amplitude. Optionally, in this embodiment, based on adjusting the vibration amplitude of the transmission system to the target vibration amplitude, a voltage signal can be acquired using a strain gauge deployed at the suspension device. The strain gauge may include a strain gauge connected to the vehicle's data acquisition system. The acquired voltage signal is converted to obtain the current force on the vehicle's suspension device. Since the current force differs depending on the target vibration amplitude, the current force on the suspension device can be determined, thereby improving the accuracy of the current force determination.

[0068] The method described below for testing abnormal noises in a vehicle based on the current force, and obtaining the test results, will be further described below.

[0069] As an optional embodiment, step S104 involves conducting an abnormal noise test on the vehicle based on the current force to obtain an abnormal noise test result, including: determining a target relationship between the current force and a preset force range; responding to the target relationship indicating that the current force is within the preset force range, conducting an abnormal noise test on the vehicle to obtain an abnormal noise test result indicating that the vehicle has successfully responded to the abnormal noise event; and responding to the target relationship indicating that the current force is not within the preset force range, conducting an abnormal noise test on the vehicle to obtain an abnormal noise test result indicating that the vehicle has not successfully responded to the abnormal noise event.

[0070] In this embodiment, the preset force range can be determined according to the type of suspension device. For example, the preset force range can be [0, 20000N]. The values ​​here are only illustrative and are not specifically limited.

[0071] In this embodiment, after determining the current force on the vehicle's suspension device based on the target transmission torque, a target relationship between the current force and a preset force range is determined. In response to the target relationship indicating that the current force is within the preset force range, an abnormal noise test is performed on the vehicle, and the abnormal noise test result indicates that the vehicle has successfully handled the abnormal noise event. Optionally, this embodiment, based on determining the current force, compares the relationship between the current force and the preset force range to obtain a target relationship between the current force and the preset force range. If the obtained target relationship indicates that the current force is within the preset force range, an abnormal noise test is performed on the vehicle, and the abnormal noise test result indicates that the vehicle has successfully handled the abnormal noise event. Since different target relationships between the current force and the preset force range result in different abnormal noise test results, the purpose of determining whether the vehicle has successfully handled the abnormal noise event is achieved, thereby improving the technical effect of improving the accuracy of abnormal noise testing on vehicles.

[0072] In this embodiment, after determining the target relationship between the current force and the preset force range, in response to the target relationship indicating that the current force is not within the preset force range, an abnormal noise test is performed on the vehicle, and the abnormal noise test result is that the vehicle has failed to cope with the abnormal noise event. Optionally, this embodiment, based on determining the current force, compares the relationship between the current force and the preset force range to obtain the target relationship between the current force and the preset force range; if the obtained target relationship indicates that the current force is not within the preset force range, then an abnormal noise test is performed on the vehicle, and the abnormal noise test result is that the vehicle has failed to cope with the abnormal noise event. Since different target relationships between the current force and the preset force range result in different abnormal noise test results, the purpose of determining whether the vehicle has successfully coped with the abnormal noise event is achieved, thereby improving the technical effect of improving the accuracy of abnormal noise testing on vehicles.

[0073] The acceleration test method for the vehicle described in this embodiment will be further described below.

[0074] As an optional embodiment, in response to the abnormal noise test result indicating that the vehicle has successfully responded to the abnormal noise, the road environment is updated to obtain the target road environment; in response to the target road environment being an asphalt pavement environment, an acceleration test is performed on the vehicle to obtain the acceleration test result, wherein the acceleration test result is used to indicate whether the vehicle's acceleration function is normal.

[0075] In this embodiment, the target road environment may include an asphalt pavement environment.

[0076] In this embodiment, in response to the abnormal noise test result indicating that the vehicle successfully responded to the abnormal noise, the road environment is updated to obtain the target road environment. Optionally, in this embodiment, if the abnormal noise test result indicates that the vehicle successfully responded to the abnormal noise, updating the aforementioned road environment can obtain the target road environment.

[0077] In this embodiment, the acceleration test results can be used to indicate whether the vehicle's acceleration function is normal. For example, the acceleration test results can indicate that the vehicle's acceleration function is normal or that the vehicle's acceleration function is abnormal. This is only an example and is not a specific limitation.

[0078] In this embodiment, after updating the road environment to obtain the target road environment in response to the abnormal noise test result indicating that the vehicle successfully handled the abnormal noise, and then performing an acceleration test on the vehicle in response to the target road environment being an asphalt pavement environment, an acceleration test result is obtained. Optionally, this embodiment, based on obtaining the target road environment, matches the target road environment with different types of road surface environments. If the target road environment is matched to an asphalt pavement environment, an acceleration test is performed on the vehicle, and an acceleration test result can be obtained. Since an acceleration test can be performed on the vehicle by switching the bumpy road environment to an asphalt pavement environment, an acceleration test result can be obtained, thereby achieving the purpose of determining whether the vehicle's acceleration function is normal, and thus achieving the technical effect of improving the accuracy of vehicle acceleration testing.

[0079] In this embodiment of the invention, when testing abnormal noises in a vehicle, the road environment in which the vehicle is driving can be detected. If the detected road environment is a bumpy surface, the vehicle's current transmission torque is adjusted to obtain a target transmission torque. Based on the adjusted target transmission torque, the current force on the vehicle's suspension system can be determined. Based on the determined current force, an abnormal noise test is performed on the vehicle, yielding the abnormal noise test result. Because this embodiment of the invention, based on determining the road environment in which the vehicle is located, adjusts the vehicle's current transmission torque to obtain a target transmission torque if the road environment is a bumpy surface, and performs an abnormal noise test on the vehicle based on the current force determined by the target transmission torque, an abnormal noise test result can be obtained. This achieves the purpose of testing whether the vehicle can cope with abnormal noises, thereby realizing the technical effect of improving the safety of the vehicle when accelerating on bumpy roads.

[0080] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0081] Currently, when a vehicle accelerates on a bumpy road, the wheel speed often fluctuates significantly due to the road surface bumps, causing the vehicle's powertrain transmission system to shake. When the frequency of the wheel speed fluctuations couples with the modal frequency of the powertrain transmission system, the powertrain transmission system resonates, causing an impact at the location of the suspension tie rod and producing abnormal noise.

[0082] However, if the impact between the powertrain drive system and the suspension tie rod is severe, it can cause the housing in the powertrain drive system to break or the suspension tie rod to break, resulting in a technical problem of low safety when the vehicle accelerates on bumpy roads.

[0083] To address the aforementioned technical problems, this invention proposes a method for testing abnormal noises in vehicles. Based on determining the road environment in which the vehicle is located, if the road environment is a bumpy surface, the current transmission torque of the vehicle is adjusted to obtain a target transmission torque. Based on the current force determined by the target transmission torque, an abnormal noise test is performed on the vehicle, yielding the test results. This achieves the goal of testing whether the vehicle can handle abnormal noises, thereby improving the safety of the vehicle when accelerating on bumpy roads.

[0084] In this embodiment, by executing the vehicle noise optimization method, a noise test can be performed on the vehicle based on the determined current force, and the noise test results can be obtained. For example, Figure 2(a) is a schematic diagram of a vehicle noise optimization method according to an embodiment of the present invention. As shown in Figure 2(a), the method may include the following steps:

[0085] Step S201: Check the vehicle's status.

[0086] In the technical solution provided by step S201 of the present invention, by checking the vehicle's condition, it can be ensured that the vehicle's torque output is normal. For example, the vehicle is accelerated in both a bumpy road environment and an asphalt road environment to confirm whether the torque output of the vehicle is normal when driving in these different road environments. When the vehicle accelerates in a bumpy road environment, the vehicle speed increases rapidly with the torque. Because the tires bounce up and down on the bumpy road, the wheel speed fluctuates accordingly, and the powertrain also shakes. When the vehicle accelerates in an asphalt road environment, the vehicle speed increases steadily with the torque.

[0087] For example, the bumpy road environment described above can be as shown in Figure 2(b). For example, Figure 2(b) is a schematic diagram of a bumpy road environment according to an embodiment of the present invention, wherein the bumpy road is an uneven road surface.

[0088] For example, the asphalt pavement environment described above can be as shown in Figure 2(c). For instance, Figure 2(c) is a schematic diagram of an asphalt pavement environment according to an embodiment of the present invention, wherein the asphalt pavement is a smooth surface.

[0089] After checking the vehicle's condition, proceed to step S202, where the vehicle's suspension forces and torques are tested on a real vehicle.

[0090] In the technical solution provided in step S202 of the present invention, strain gauges are arranged in the middle section of the rear suspension tie rod of the vehicle. The calibrated strain gauges can be installed on each tie rod of the vehicle and connected to the vehicle's data acquisition system to test the force on the suspension tie rod. The vehicle throttle opening signal, powertrain output torque signal, and wheel speed signal are read simultaneously.

[0091] It should be noted that, for ease of comparison, the test condition selected was a bumpy road with full throttle acceleration and start-up. The vehicle began accelerating 1 meter away from the bumpy road surface, and the full throttle operation was completed within 0.5 seconds, accelerating to 80 km / h to end the test. For example, the bumpy road surface mentioned above is a dry bumpy road surface, and the number of tests is no less than 3. The values ​​here are only for illustrative purposes and are not specific limitations.

[0092] After testing the suspension forces and torques of the vehicle in the actual vehicle test, proceed to step S203 to analyze and process the test data.

[0093] In the technical solution provided by step S203 of the present invention, the voltage signal obtained by strain gauge testing is converted into the force signal of the suspension rod, thereby obtaining the current force on the suspension rod.

[0094] After analyzing and processing the data obtained from the test, proceed to step S204 to conduct an abnormal noise test on the vehicle.

[0095] In the technical solution provided in step S204 of the present invention, since the impact noise occurs at the moment of wheel speed fluctuation, the proposed optimization scheme is to adjust the actual torque at the moment the wheel speed begins to fluctuate. For example, when the wheel speed fluctuation exceeds 200 rpm, 500 rpm, and 800 rpm, the total power output torque is reduced to 30%, 50%, and 80% of the torque at that moment, respectively, within 0.1 seconds. Steps S202 and S203 are repeated during the adjustment process to test the current force on the suspension tie rod. If the current force does not exceed the maximum force value of a single suspension tie rod (for example, 20000N), the vehicle's noise test result is determined to be that the vehicle has successfully responded to the noise event.

[0096] It should be noted that after confirming that the vehicle's acceleration and impact noises on bumpy roads and its driving dynamics and drivability are acceptable, the acceleration performance on asphalt roads will then be verified to ensure it is not affected. Since this adjustment is only applicable when wheel speed fluctuations are significant, this solution does not affect the vehicle's overall performance on asphalt roads.

[0097] After conducting the abnormal noise test on the vehicle, proceed to step S205 to determine whether the abnormal noise test result indicates that the vehicle has successfully responded to the abnormal noise event.

[0098] If the abnormal noise test result indicates that the vehicle failed to respond to the abnormal noise event, proceed to step S202.

[0099] If the abnormal noise test result indicates that the vehicle has successfully handled the abnormal noise event, proceed to step S206 to determine the abnormal noise optimization plan.

[0100] In the technical solution provided by step S206 of the present invention, the proposed optimization scheme is determined as the abnormal noise optimization scheme.

[0101] For example, the wheel speed and torque in the unoptimized state and the wheel speed and torque in the optimized state can be as shown in Figure 2(d). For example, Figure 2(d) is a schematic diagram of wheel speed and torque in the unoptimized state and the optimized state according to an embodiment of the present invention. After the moment when the wheel speed begins to fluctuate, the wheel speed and torque in the unoptimized state begin to fluctuate; however, after the moment when the torque is limited, the wheel speed and torque in the optimized state maintain a smooth transition without fluctuation.

[0102] In this embodiment, when testing for abnormal noises in a vehicle, the road environment in which the vehicle is driving can be detected. If the detected road environment is a bumpy surface, the vehicle's current transmission torque is adjusted to obtain a target transmission torque. Based on the adjusted target transmission torque, the current force on the vehicle's suspension system can be determined. Based on this determined current force, an abnormal noise test is performed on the vehicle, yielding the abnormal noise test results. Because this embodiment of the invention, based on determining the road environment in which the vehicle is located, adjusts the vehicle's current transmission torque to obtain a target transmission torque if the road environment is a bumpy surface, and performs an abnormal noise test on the vehicle based on the current force determined by the target transmission torque, the abnormal noise test results are obtained. This achieves the goal of testing whether the vehicle can cope with abnormal noises, thereby realizing the technical effect of improving the safety of the vehicle when accelerating on bumpy roads.
