[0028] In order to make the personnel in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0029] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] According to an embodiment of the present application, a vehicle abnormal sound testing method is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0031] Figure 1 is a flowchart of a vehicle abnormal sound testing method according to an embodiment of the present application, as shown in Figure 1 The method can include the following steps:

[0032] Step S101, detecting the road environment in which the vehicle is located in the driving state.

[0033] In the technical solution provided by the above step S101 of the present application, the road environment can be different types of road surface environment. For example, different types of road surface environment can include: bumpy road surface environment, asphalt road surface environment, soil road surface environment, and race track road surface environment, etc., which are only used as examples and are not specifically limited.

[0034] In this embodiment, the road environment in which the vehicle is located in the driving state is detected. Optionally, this embodiment can obtain driving data of the vehicle in the driving state, and image data of the vehicle in the driving state, wherein the driving data can include the speed, acceleration and brake data of the vehicle, and the image data can be used to represent the surrounding environment of the vehicle. The environment recognition result can be obtained by performing environment recognition on the above driving data, wherein the environment recognition result can be used to represent a first initial road environment matched with the above driving data; from the above image data, a second initial road environment included in the above surrounding environment can be determined, and the environment similarity between the first initial road environment and the second initial road environment can be determined; and according to the environment similarity between the first initial road environment and the second initial road environment, the road environment in which the vehicle is located in the driving state can be detected.

[0035] Optionally, the road environment in which the vehicle is located in the driving state can be detected according to the environment similarity between the first initial road environment and the second initial road environment. For example, if the environment similarity is greater than or equal to a preset environment similarity, the first initial road environment and the second initial road environment are merged into the same road environment, so that the road environment in which the vehicle is located in the driving state can be detected.

[0036] Optionally, the road environment in which the vehicle is located in the driving state can be detected according to the environment similarity. For example, if the environment similarity is less than the preset environment similarity, the first initial road environment and the second initial road environment are fused to obtain a fused road environment, and the obtained fused road environment is determined as the road environment in which the vehicle is located in the driving state, so that the road environment in which the vehicle is located in the driving state can be detected.

[0037] It should be noted that the above preset environment similarity can be set according to the occurrence frequency 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 occurrence frequency of the bumpy road environment is 7 times per cycle, the preset environment similarity can be 95%, and the value is only used as an example and is not limited.

[0038] In step S102, in response to the road environment being a bumpy road environment, the current driving torque of the vehicle is adjusted to obtain a target driving torque, wherein the current driving torque is the torque output by the driving system of the vehicle, and the target driving torque is used to limit the current vibration amplitude of the driving system.

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

[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 currently driving, the current transmission torque of the vehicle is adjusted to obtain the target transmission torque in response to the road environment being a bumpy road environment. Optionally, this embodiment matches the detected road environment with different types of road environments based on the detected road environment, and if the detected road environment is matched to 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 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 the bumpy road environment, the road environment is switched to the bumpy road environment, and if the switched road environment is the 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 a torque that limits the current vibration amplitude of the transmission system.

[0043] In step S103, the current force of the suspension device of the vehicle is determined based on the target transmission torque, wherein the current force is used to represent the force acting between the transmission system and the wheels of the vehicle.

[0044] In the technical solution provided in the step S103 of the present application, the current force can be used to represent the force acting between the transmission system and the wheels of the vehicle. For example, if the suspension device is a suspension pull rod, the current force can be the force acting between the transmission system and the wheels of the vehicle.

[0045] In this embodiment, after the current driving torque of the vehicle is adjusted to obtain the target driving torque in response to the road environment being the bumpy road environment, the current force of the suspension device of the vehicle is determined based on the target driving torque. Optionally, the vibration amplitude of the driving system can be adjusted from the current vibration amplitude to the target vibration amplitude based on the target driving torque obtained by the adjustment, and the current force of the suspension device of the vehicle can be determined when the vibration amplitude of the driving system is adjusted to the target vibration amplitude.

[0046] In step S104, the vehicle is subjected to the abnormal sound test based on the current force to obtain an abnormal sound test result, wherein the abnormal sound test result is used to indicate whether the vehicle successfully copes with an abnormal sound event, and the abnormal sound event is used to indicate that the abnormal sound is generated by the impact between the driving system and the suspension device in the bumpy road environment.

[0047] In the technical solution provided by the above step S104 of the present application, the above abnormal sound test result can be used to indicate whether the vehicle successfully copes with the abnormal sound event. For example, the above abnormal sound test result can be that the vehicle successfully copes with the abnormal sound event, or that the vehicle fails to cope with the abnormal sound event, which is only exemplified and not specifically limited.

[0048] In this embodiment, the above abnormal sound event can be used to indicate that the abnormal sound is generated by the impact between the driving system and the suspension device in the bumpy road environment. For example, if the driving system is a powertrain driving system and the suspension device is a suspension pull rod, the above abnormal sound event can be used to indicate that the abnormal sound is generated by the impact between the powertrain driving system and the suspension pull rod in the bumpy road environment.

[0049] In this embodiment, after the current force of the suspension device of the vehicle is determined based on the target driving torque, the vehicle is subjected to the abnormal sound test based on the current force to obtain an abnormal sound test result. Optionally, the target relationship between the above current force and the preset force range can be determined based on the current force. According to the abnormal sound test of the vehicle based on the above target relationship, the abnormal sound test result can be obtained, thereby achieving the purpose of testing whether the vehicle can cope with the abnormal sound.

[0050] It should be noted that the above preset force range can be determined according to the type of the suspension device. For example, if the type of the suspension device is a coil spring type, the above preset force range can be a force range corresponding to the coil spring type; if the type of the suspension device is a non-coil spring type, the above preset force range can be a force range corresponding to the non-coil spring type, which is only exemplified and not specifically limited.

[0051] The above steps S101 to S104 of the application can detect the road environment in which the vehicle is located in the driving state when testing the abnormal sound of the vehicle, adjust the current driving torque of the vehicle in response to the detected road environment being a bumpy road surface environment, obtain a target driving torque, determine the current stress of the suspension device of the vehicle based on the target driving torque obtained by adjustment, and test the abnormal sound of the vehicle based on the determined current stress, so as to obtain the abnormal sound test result. Since the embodiment of the application is based on the determination of the road environment in which the vehicle is located, if the road environment is a bumpy road surface environment, the current driving torque of the vehicle is adjusted to obtain a target driving torque, and the abnormal sound of the vehicle is tested based on the current stress determined by the target driving torque, so as to obtain the abnormal sound test result, thereby achieving the purpose of testing whether the vehicle can cope with the abnormal sound, thereby realizing the technical effect of improving the safety of the vehicle when accelerating on a bumpy road.

[0052] The method of adjusting the current driving torque of the vehicle to obtain a target driving torque in response to the road environment being a bumpy road surface environment of the above embodiment will be further introduced below.

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

[0054] In this embodiment, the current speed can be used to indicate the current rotation speed of the wheel, and the current speed can be associated with the current power of the driving system.

[0055] In this embodiment, the target adjustment strategy can be used to indicate the way of adjusting the current driving torque.

[0056] In this embodiment, after detecting the road environment in which the vehicle is located in the driving state, a target adjustment strategy for the current driving torque is determined based on the current speed of the wheel in response to the road environment being a bumpy road surface environment. Alternatively, the embodiment matches the detected road environment with different types of road surface environments based on the detection of the road environment, and if the detected road environment is matched to a bumpy road surface environment, a target adjustment strategy for the current driving torque can be determined based on the current speed of the wheel.

[0057] In this embodiment, in response to the road environment being a bumpy road environment, based on the current rotating speed of the wheel, the target adjustment strategy about the current driving torque is determined, and then the current driving torque is adjusted according to the target adjustment strategy to obtain the target driving torque. Alternatively, based on the determination of the target adjustment strategy, the current driving torque is adjusted according to the determined target adjustment strategy to obtain the target driving torque. Since the current driving torque of the vehicle is adjusted based on the determination of the target adjustment strategy to obtain the target driving torque, the purpose of adjusting the current driving torque of the vehicle is achieved, and the technical effect of improving the flexibility of the driving torque of the vehicle is realized.

[0058] The method of determining the target adjustment strategy about the current driving torque based on the current rotating speed of the wheel in the above embodiment will be further described below.

[0059] As an optional embodiment, the method of determining the target adjustment strategy about the current driving torque based on the current rotating speed of the wheel comprises: obtaining a previous rotating speed of the current rotating speed; determining a rotating speed fluctuation amplitude between the current rotating speed and the previous rotating speed; and determining the target adjustment strategy corresponding to the rotating speed fluctuation amplitude.

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

[0061] In this embodiment, the target adjustment strategy can correspond to the rotating speed fluctuation amplitude one by one. For example, if the rotating speed fluctuation amplitude is 200 rpm, the target adjustment strategy can be a first target adjustment strategy, which can be used to represent a way of adjusting the current driving torque to decrease by 30%; if the rotating speed fluctuation amplitude is 500 rpm, the target adjustment strategy can be a second target adjustment strategy, which can be used to represent a way of adjusting the current driving torque to decrease by 50%; if the rotating speed fluctuation amplitude is 800 rpm, the target adjustment strategy can be a third target adjustment strategy, which can be used to represent a way of adjusting the current driving torque to decrease by 80%. The values herein are only used for illustration and are not limited.

[0062] In this embodiment, after detecting the road environment in which the vehicle is located in the driving state, the previous rotation speed of the current rotation speed is obtained; the rotation speed fluctuation amplitude between the current rotation speed and the previous rotation speed is determined; and the target adjustment strategy corresponding to the rotation speed fluctuation amplitude is determined. Optionally, based on the detection of the road environment, the current rotation speed of the wheel and the previous rotation speed of the current rotation speed are obtained; the current rotation speed and the previous rotation speed are calculated by difference, so as to obtain the rotation speed fluctuation amplitude between the current rotation speed and the previous rotation speed; then, according to the target adjustment strategy corresponding to different rotation speed fluctuation amplitudes, the target adjustment strategy corresponding to the above-mentioned rotation speed fluctuation amplitude can be found. Since the target adjustment strategy is corresponding to the rotation speed fluctuation amplitude, the purpose of determining the target adjustment strategy corresponding to the rotation speed fluctuation amplitude is achieved, and the technical effect of improving the accuracy of the target adjustment strategy is realized.

[0063] Optionally, if the above-mentioned rotation speed fluctuation amplitude is 210 rpm, according to the target adjustment strategy corresponding to different rotation speed fluctuation amplitudes, the first target adjustment strategy corresponding to the above-mentioned rotation speed fluctuation amplitude of 210 rpm can be found, and the found first target adjustment strategy is determined as the target adjustment strategy corresponding to the rotation speed fluctuation amplitude; if the above-mentioned rotation speed fluctuation amplitude is 520 rpm, according to the target adjustment strategy corresponding to different rotation speed fluctuation amplitudes, the second target adjustment strategy corresponding to the above-mentioned rotation speed fluctuation amplitude of 520 rpm can be found, and the found second target adjustment strategy is determined as the target adjustment strategy corresponding to the rotation speed fluctuation amplitude; if the above-mentioned rotation speed fluctuation amplitude is 830 rpm, according to the target adjustment strategy corresponding to different rotation speed fluctuation amplitudes, the third target adjustment strategy corresponding to the above-mentioned rotation speed fluctuation amplitude of 830 rpm can be found, and the found third target adjustment strategy is determined as the target adjustment strategy corresponding to the rotation speed fluctuation amplitude. The values here are only for example and are not limited.

[0064] The above-mentioned method for determining the current stress of the suspension device of the vehicle based on the target transmission torque of this embodiment will be further introduced below.

[0065] As an optional embodiment, step S103, determining the current stress of the suspension device of the vehicle based on the target transmission torque, comprises: 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 stress under the target vibration amplitude.

[0066] In this embodiment, after the target driving torque is obtained by adjusting the current driving torque of the vehicle in response to the road environment being the bumpy road environment, the vibration amplitude of the driving system is adjusted from the current vibration amplitude to the target vibration amplitude according to the target driving torque. Optionally, on the basis of the target driving torque obtained by adjustment, the vibration amplitude of the driving system can be adjusted from the current vibration amplitude to the target vibration amplitude according to the target driving torque.

[0067] In this embodiment, after the vibration amplitude of the driving system is adjusted from the current vibration amplitude to the target vibration amplitude according to the target driving torque, the current force is determined at the target vibration amplitude. Optionally, on the basis of the vibration amplitude of the driving system being adjusted to the target vibration amplitude, in the case where the vibration amplitude of the driving system has been adjusted to the target vibration amplitude, the voltage signal can be collected by using the strain device arranged at the suspension device, wherein the strain device can include a strain gauge connected to the data acquisition system of the vehicle; and the current force of the suspension device of the vehicle can be obtained by converting the collected voltage signal. Since the current force is different if the target vibration amplitude to which the adjustment is made is different, the purpose of determining the current force of the suspension device is achieved, and the technical effect of improving the accuracy of the current force is realized.

[0068] The method for determining the current force of the suspension device based on the above-mentioned current force and the method for testing the abnormal sound of the vehicle and obtaining the abnormal sound test result of the vehicle will be further introduced below.

[0069] As an optional embodiment, step S104, determining the current force of the suspension device based on the current force and the method for testing the abnormal sound of the vehicle and obtaining the abnormal sound test result of the vehicle, includes: determining the target relationship between the current force and the preset force interval; in response to the target relationship indicating that the current force is within the preset force interval, testing the abnormal sound of the vehicle to obtain the abnormal sound test result as the vehicle successfully coping with the abnormal sound event; and in response to the target relationship indicating that the current force is not within the preset force interval, testing the abnormal sound of the vehicle to obtain the abnormal sound test result as the vehicle failing to successfully cope with the abnormal sound event.

[0070] In this embodiment, the above-mentioned preset force interval can be determined according to the type of the suspension device. For example, the above-mentioned preset force interval can be [0, 20000N], and the values herein are only illustrative and are not limited in specific.

[0071] In this embodiment, after determining the current force of the suspension device of the vehicle based on the target driving torque, a target relationship between the current force and the preset force range is determined; in response to the target relationship indicating that the current force is within the preset force range, the vehicle is subjected to the abnormal sound test, and the abnormal sound test result is that the vehicle successfully copes with the abnormal sound event. Optionally, the relationship between the current force and the preset force range is compared based on the determined current force, and the target relationship between the current force and the preset force range is obtained; if the obtained target relationship indicates that the current force is within the preset force range, the vehicle is subjected to the abnormal sound test, and the abnormal sound test result is that the vehicle successfully copes with the abnormal sound event. Since the abnormal sound test result obtained by subjecting the vehicle to the abnormal sound test is different if the target relationship between the current force and the preset force range is different, the purpose of determining whether the vehicle successfully copes with the abnormal sound event is achieved, and the technical effect of improving the accuracy of the abnormal sound test on the vehicle is achieved.

[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, the vehicle is subjected to the abnormal sound test, and the abnormal sound test result is that the vehicle does not successfully cope with the abnormal sound event. Optionally, the relationship between the current force and the preset force range is compared based on the determined current force, and the target relationship between the current force and the preset force range is obtained; if the obtained target relationship indicates that the current force is not within the preset force range, the vehicle is subjected to the abnormal sound test, and the abnormal sound test result is that the vehicle does not successfully cope with the abnormal sound event. Since the abnormal sound test result obtained by subjecting the vehicle to the abnormal sound test is different if the target relationship between the current force and the preset force range is different, the purpose of determining whether the vehicle successfully copes with the abnormal sound event is achieved, and the technical effect of improving the accuracy of the abnormal sound test on the vehicle is achieved.

[0073] The above vehicle acceleration test method of this embodiment is further introduced as follows.

[0074] As an optional embodiment, in response to the abnormal sound test result being that the vehicle successfully copes with the abnormal sound, the road environment is updated to obtain a target road environment; in response to the target road environment being an asphalt pavement environment, the vehicle is subjected to the acceleration test, and the acceleration test result is obtained, wherein the acceleration test result is used to indicate whether the acceleration function of the vehicle is normal.

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

[0076] In this embodiment, in response to the result of the abnormal sound test indicating that the vehicle successfully copes with the abnormal sound, the road environment is updated to obtain a target road environment. Optionally, in the case where the result of the abnormal sound test in this embodiment indicates that the vehicle successfully copes with the abnormal sound, the road environment is updated to obtain the target road environment.

[0077] In this embodiment, the acceleration test result can be used to indicate whether the acceleration function of the vehicle is normal. For example, the acceleration test result can indicate that the acceleration function of the vehicle is normal or that the acceleration function of the vehicle is abnormal, which is only illustrative and not limited.

[0078] In this embodiment, after the road environment is updated to obtain a target road environment in response to the result of the abnormal sound test indicating that the vehicle successfully copes with the abnormal sound, the vehicle is subjected to an acceleration test in response to the target road environment being an asphalt road environment to obtain an acceleration test result. Optionally, in this embodiment, the target road environment is matched with different types of road environments on the basis of the obtained target road environment, and if the target road environment is matched to an asphalt road environment, the vehicle is subjected to an acceleration test to obtain the acceleration test result. Since the vehicle is subjected to an acceleration test in the case where the bumpy road environment in which the vehicle is located is switched to an asphalt road environment, the acceleration test result can be obtained, thereby achieving the purpose of determining whether the acceleration function of the vehicle is normal, and further achieving the technical effect of improving the accuracy of the acceleration test of the vehicle.

[0079] In the embodiment of the present application, when testing the abnormal sound of the vehicle, the road environment in which the vehicle is located in the driving state can be detected, the current driving torque of the vehicle is adjusted to obtain a target driving torque in response to the detected road environment being a bumpy road environment, the current stress of the suspension device of the vehicle can be determined on the basis of the target driving torque obtained by the adjustment, and the vehicle is subjected to an abnormal sound test on the basis of the determined current stress to obtain an abnormal sound test result. Since in the embodiment of the present application, if the road environment in which the vehicle is located is a bumpy road environment, the current driving torque of the vehicle is adjusted to obtain a target driving torque, and the vehicle is subjected to an abnormal sound test on the basis of the current stress determined by the target driving torque to obtain an abnormal sound test result, the purpose of testing whether the vehicle can cope with the abnormal sound is achieved, thereby achieving the technical effect of improving the safety of the vehicle when accelerating on a bumpy road.

[0080] The technical solutions of the embodiments of the present application will be described below in conjunction with preferred embodiments.

[0081] Currently, when the vehicle is accelerated on a bumpy road, the wheel speed fluctuates greatly due to the influence of the bumpy road, and the powertrain system of the vehicle also shakes. When the fluctuation frequency of the wheel speed is coupled with the modal frequency of the powertrain system, the powertrain system resonates, and the impact on the suspension pull rod occurs, causing an abnormal noise.

[0082] However, if the impact of the powertrain system on the suspension pull rod is severe, it will cause the shell in the powertrain system to break or the suspension pull rod to break, thereby causing the technical problem of low safety of the vehicle when accelerating on a bumpy road.

[0083] To solve the above technical problem, the embodiment of the present application provides a vehicle abnormal noise test method. Based on the determination of the road environment of the vehicle, if the road environment is a bumpy road environment, the current transmission torque of the vehicle is adjusted to obtain a target transmission torque, and the vehicle is tested for abnormal noise based on the current stress determined by the target transmission torque. The abnormal noise test result can be obtained, thereby achieving 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.

[0084] In this embodiment, by executing the vehicle abnormal noise optimization method, the vehicle can be tested for abnormal noise based on the determined current stress to obtain an abnormal noise test result. For example, FIG. 2(a) is a schematic diagram of a vehicle abnormal noise optimization method according to an embodiment of the present application. As shown in FIG. 2(a), the method can include the following steps:

[0085] Step S201, check the state of the vehicle.

[0086] In the technical solution provided in the above step S201 of the present application, by checking the state of the vehicle, it can be ensured that the torque output of the vehicle is normal. For example, the vehicle is accelerated on a bumpy road and on an asphalt road, respectively, to confirm whether the torque output of the vehicle is normal when the vehicle is driven on the above different road surfaces. When the vehicle is accelerated on a bumpy road, the vehicle speed rises rapidly with the torque, and since the tires are bumpy on the bumpy road, the wheel speed fluctuates up and down, and the powertrain also shakes; when the vehicle is accelerated on an asphalt road, the vehicle speed rises steadily with the torque.

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

[0088] For example, the asphalt pavement environment described above can be as shown in Fig. 2(c). For example, Fig. 2(c) is a schematic diagram of an asphalt pavement environment according to an embodiment of the present application, and the asphalt pavement is a flat road.

[0089] After checking the state of the vehicle, enter step S202 to test the suspension force and torque of the vehicle.

[0090] In the technical solution provided by the above step S202 of the present application, the strain gauge is arranged at the middle segment position of the rear suspension pull rod of the vehicle. The calibrated strain gauge can be installed on each pull rod of the whole vehicle, and the calibrated strain gauge can be connected to the data acquisition system of the vehicle, so as to test the force of the suspension pull rod. The vehicle throttle opening signal, the total output torque signal and the wheel speed signal are read synchronously.

[0091] It should be noted that, in order to facilitate comparison, the test condition is selected as the full throttle acceleration starting condition on the bumpy road, the vehicle starts to accelerate at a distance of 1 meter from the bumpy road, and the full throttle operation is completed within 0.5 seconds. Accelerate to 80km / h to end the test. For example, the bumpy road described above is a dry bumpy road, and the number of tests described above is not less than 3 times, and the values herein are only for example and are not specifically limited.

[0092] After testing the suspension force and torque of the vehicle, enter step S203 to analyze and process the test data.

[0093] In the technical solution provided by the above step S203 of the present application, the voltage signal obtained by the strain gauge is converted into the force signal of the suspension pull rod, so as to obtain the current force of the suspension pull rod.

[0094] After analyzing and processing the test data, enter step S204 to test the abnormal sound of the vehicle.

[0095] In the technical solution provided by the above step S204 of the present application, since the impact abnormal sound occurs at the wheel speed fluctuation time, the optimization scheme is proposed as follows: adjusting the actual torque when the wheel speed starts to fluctuate. For example, when the wheel speed fluctuation exceeds 200rpm, 500rpm, 800rpm, the total output torque is reduced to 30%, 50%, 80% of the torque at that time within 0.1 seconds. Repeat steps S202 and S203 during the adjustment process to test the current force of the suspension pull rod. If the current force does not exceed the maximum force of a single suspension pull rod (for example, 20000N), it is determined that the abnormal sound test result of the vehicle is that the vehicle successfully copes with the abnormal sound event.

[0096] It should be noted that after confirming that the acceleration impact abnormal noise on the bumpy road and the driving dynamics and drivability are acceptable, the acceleration performance of the vehicle in the asphalt pavement environment is verified again so as to not be affected. Since the adjustment is only applicable when the wheel speed fluctuation is large, the scheme does not affect the performance of the vehicle in the asphalt pavement.

[0097] After the vehicle is tested for abnormal noise, step S205 is entered to determine whether the abnormal noise test result is that the vehicle successfully copes with the abnormal noise event.

[0098] If it is determined that the abnormal noise test result is that the vehicle does not successfully cope with the abnormal noise event, step S202 is entered.

[0099] If it is determined that the abnormal noise test result is that the vehicle successfully copes with the abnormal noise event, step S206 is entered to determine an abnormal noise optimization scheme.

[0100] In the technical scheme provided in step S206 of the present application, the above-mentioned 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 FIG. 2(d). For example, FIG. 2(d) is a schematic diagram of wheel speed and torque in an unoptimized state and an optimized state according to an embodiment of the present application. After the time when the wheel speed starts to fluctuate, the wheel speed and torque in the unoptimized state start to fluctuate. However, after the time when the torque is limited, the wheel speed and torque in the optimized state remain smooth and do not fluctuate.

[0102] In this embodiment, when testing the abnormal noise of the vehicle, the road environment in which the vehicle is located in the driving state can be detected. In response to the detected road environment being a bumpy road environment, the current driving torque of the vehicle is adjusted to obtain a target driving torque. Based on the target driving torque obtained by the adjustment, the current stress of the suspension device of the vehicle can be determined, and based on the determined current stress, the vehicle is tested for abnormal noise to obtain an abnormal noise test result. Since the embodiment of the present application is based on the determination of the road environment in which the vehicle is located. If the road environment is a bumpy road environment, the current driving torque of the vehicle is adjusted to obtain a target driving torque, and based on the current stress determined by the target driving torque, the vehicle is tested for abnormal noise to obtain an abnormal noise test result, thereby achieving 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.
