Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an electric drive whistling control method, device, electronic equipment, and vehicle. Background Technology

[0002] With economic development and improved living standards, automobiles have become an indispensable means of transportation in people's daily lives. In recent years, the market share of new energy vehicles has continued to increase. Because the power source of new energy vehicles has changed from the traditional fuel engine to a drive motor, the low-frequency noise generated by the engine is reduced during vehicle operation. Therefore, compared with traditional vehicles, the interior environment of new energy vehicles is quieter, and when a vehicle whistles, it is easier to detect in new energy vehicles than in traditional fuel vehicles.

[0003] In one related technology, the gear squeal value of the target vehicle at a target constant speed is determined. If the gear squeal value exceeds a preset squeal value, the torque distribution ratio between the front and rear electric drive systems is determined based on the gear squeal value. This torque distribution ratio is then adjusted to reduce the gear squeal value. Another related technology involves acquiring a distribution map of the vehicle's operating conditions under different operating conditions. Based on this map, multiple sets of engine torques are obtained at different throttle openings and engine speeds. These engine torques are then used to determine multiple target torque requirements for the vehicle. A torque control boundary line is established for each operating condition based on these target torque requirements. The vehicle's current engine torque is then adjusted according to this boundary line. Both of these methods only consider reducing vehicle squeal by adjusting the electric drive torque, without considering the impact of adding or distributing torque on the vehicle's range. Summary of the Invention

[0004] The purpose of this invention is to provide an electric drive whistling control method, device, electronic device, and vehicle, aiming to solve the technical problem that the continuous addition or distribution of torque to the vehicle across the entire speed range of vehicle operation affects the vehicle's range.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0006] In a first aspect, embodiments of this application provide an electric drive whistling control method, the method comprising: acquiring the rotational noise of the vehicle's auxiliary drive system and the operating status of a target device of the vehicle; the target device being a device capable of affecting the in-vehicle acoustic environment; and determining, based on the rotational noise of the auxiliary drive system and the operating status of the target device, whether to apply torque to the vehicle's auxiliary drive system, the torque being used to reduce the whistling of the auxiliary drive system.

[0007] Based on the aforementioned technical means, and considering the rotational noise of the auxiliary drive system and the operating status of the target device, it is determined whether to apply torque to the vehicle's auxiliary drive system. The target device is any device capable of affecting the in-vehicle acoustic environment. It can be seen that the electric drive whistling control method provided in this application embodiment considers that when the in-vehicle acoustic environment is affected, the user is less likely to perceive the whistling of the auxiliary drive system. Based on this, determining whether to apply torque to the vehicle's auxiliary drive system can effectively reduce the number and duration of torque applications to the auxiliary drive system during vehicle operation, thereby improving the vehicle's range without affecting the user's riding experience.

[0008] In one possible implementation, determining whether to apply torque to the vehicle's auxiliary drive system based on the rotational noise of the auxiliary drive system and the operating state of the target device includes: determining to apply torque to the auxiliary drive system when the target device is in a closed state and the rotational noise of the auxiliary drive system is greater than a preset noise value.

[0009] Based on the above technical means, when the target device is in the off state and the rotational noise of the auxiliary drive system is greater than the preset noise value, applying torque to the auxiliary drive system can effectively control the whistling of the auxiliary drive system and improve the driving comfort of the vehicle.

[0010] In one possible implementation, determining whether to apply torque to the vehicle's auxiliary drive system based on the rotational noise of the auxiliary drive system and the operating state of the target device includes: determining not to apply torque to the auxiliary drive system when the rotational noise of the auxiliary drive system is less than or equal to a preset noise value; or determining not to apply torque to the auxiliary drive system when the rotational noise of the auxiliary drive system is greater than the preset noise value and the target device is in the on state.

[0011] Based on the above technical means, when the target device is in the on state or the rotational noise of the auxiliary drive system is less than or equal to the preset noise value, the whistling of the auxiliary drive system is not easily detected. Torque can be applied to the auxiliary drive system without affecting the user's riding experience, thereby improving the vehicle's range.

[0012] In one possible implementation, the preset noise value is determined based on the vehicle's driving state and a preset correspondence; wherein the preset correspondence is used to indicate the preset noise threshold corresponding to the vehicle under different driving states.

[0013] Based on the aforementioned technical means, by determining the preset noise value through the vehicle's driving state and a preset correspondence, the preset noise threshold can be judged in real time based on the vehicle's driving state. This allows for a more accurate determination of whether torque is being applied to the auxiliary drive system, improving the accuracy of the electric drive whistling control method. Furthermore, this application is applicable to different vehicle driving states, enhancing the flexibility of the electric drive whistling control method.

[0014] In one possible implementation, the vehicle's driving state is determined based on the vehicle's operating data; the vehicle's operating data includes at least one of the following: vehicle speed, motor speed, motor torque, and accelerator pedal opening.

[0015] Based on the aforementioned technical means, the vehicle's driving status can be determined in real time through the vehicle's operating data, which can more accurately judge the vehicle's driving status. At the same time, the vehicle's operating data includes multiple factors such as vehicle speed, motor speed, motor torque, and accelerator pedal opening, making the vehicle's driving status more comprehensive and thus improving the accuracy of the electric drive whistling control method.

[0016] In one possible implementation, the target device includes at least one of the following: a car window, a speaker, an air conditioner, and a low-speed warning sound device.

[0017] Based on the aforementioned technical means, and taking into account multiple devices such as car windows, speakers, air conditioning, and low-speed warning sounds, factors that can affect the vehicle's sound environment are comprehensively considered. This can effectively reduce the possibility of applying torque to the auxiliary drive system and improve the vehicle's range.

[0018] In one possible implementation, after determining that torque is applied to the vehicle's auxiliary drive system, the method further includes: stopping the application of torque to the auxiliary drive system when preset conditions are met; wherein the preset conditions include at least one of the following: after applying torque to the auxiliary drive system, the vehicle speed changes from a first speed range to a second speed range; after applying torque to the auxiliary drive system, the vehicle travels a distance greater than or equal to a preset distance; and after applying torque to the auxiliary drive system, the vehicle travels for a time greater than or equal to a preset time.

[0019] Based on the aforementioned technical means, by setting preset conditions, the torque of the auxiliary drive system can be canceled when the preset conditions are met. This allows the torque of the auxiliary drive system to be canceled during vehicle operation based on real-time changes in vehicle speed, driving distance, or driving time, thereby improving the vehicle's range.

[0020] In one possible implementation, acquiring the rotational noise of the vehicle's auxiliary drive system and the operating status of the vehicle's target device includes: acquiring the rotational noise of the auxiliary drive system and the operating status of the target device when the vehicle speed changes from a first speed range to a second speed range; or acquiring the rotational noise of the auxiliary drive system and the operating status of the target device at preset time intervals; or acquiring the rotational noise of the auxiliary drive system and the operating status of the target device every preset distance traveled.

[0021] Based on the aforementioned technical means, the following noise of the auxiliary drive system and the working status of the target equipment are periodically acquired based on vehicle speed, preset time period, or preset driving distance. This avoids continuously applying torque to the vehicle after it starts whistling, thereby reducing the time the vehicle applies torque and improving the vehicle's range.

[0022] In one possible implementation, when it is determined that a torque is applied to the vehicle's auxiliary drive system, the method further includes: determining the target torque value applied to the auxiliary drive system based on the rotational noise of the auxiliary drive system.

[0023] Based on the above technical means, the target torque value applied by the auxiliary drive system can be determined by the rotational noise of the auxiliary drive system, which can reduce the impact of rotational noise on the vehicle driving experience. At the same time, the target torque value applied by the auxiliary drive system can be more accurately determined by the rotational noise of the auxiliary drive system, thus improving the accuracy of the motor whistling method.

[0025] In one possible implementation, the processing module is specifically configured to determine to apply torque to the auxiliary drive system when the target device is in a closed state and the rotational noise of the auxiliary drive system is greater than a preset noise value.

[0026] In one possible implementation, the processing module is specifically configured to determine not to apply torque to the auxiliary drive system when the rotational noise of the auxiliary drive system is less than or equal to a preset noise value; or, when the rotational noise of the auxiliary drive system is greater than the preset noise value and the target device is in the on state, determine not to apply torque to the auxiliary drive system.

[0027] In one possible implementation, the preset noise value is determined based on the vehicle's driving state and a preset correspondence; wherein the preset correspondence is used to indicate the preset noise threshold corresponding to the vehicle under different driving states.

[0028] In one possible implementation, the vehicle's driving status is determined based on the vehicle's operating data; the vehicle's operating data includes at least one of the following: vehicle speed, motor speed, motor torque, and accelerator pedal opening.

[0029] In one possible implementation, the target device includes at least one of the following: a vehicle, a speaker, an air conditioner, and a low-speed warning sound device.

[0030] In one possible implementation, after determining that torque is applied to the vehicle's auxiliary drive system, the processing module is further configured to stop applying torque to the auxiliary drive system if preset conditions are met; wherein the preset conditions include at least one of the following: after applying torque to the auxiliary drive system, the vehicle speed changes from a first speed range to a second speed range; after applying torque to the auxiliary drive system, the vehicle travels a distance greater than or equal to a preset distance; and after applying torque to the auxiliary drive system, the vehicle travels for a time greater than or equal to a preset time.

[0031] In one possible implementation, the communication module is specifically used to acquire the rotational noise of the auxiliary drive system and the operating status of the target device when the vehicle speed enters the second speed range from the first speed range; or, to acquire the rotational noise of the auxiliary drive system and the operating status of the target device at preset time intervals; or, to acquire the rotational noise of the auxiliary drive system and the operating status of the target device every preset distance traveled.

[0032] In one possible implementation, if it is determined that torque is applied to the vehicle's auxiliary drive system, the processing module is further configured to determine the target torque value applied to the auxiliary drive system based on the rotational noise of the auxiliary drive system.

[0048] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application 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 this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0051] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0052] For new energy four-wheel drive vehicles, in some Ecology Economy Mode (ECO) or other low-torque operating conditions, the auxiliary drive system does not output torque. When the auxiliary drive system is in the off state, since it is not powered on, the motor does not generate output torque, causing the primary and secondary driven gears of the auxiliary drive system to not fully engage. Furthermore, the shaft system of the auxiliary drive system can rotate freely without a fixed direction of rotation, making it susceptible to interference from external factors. Due to the unstable meshing state of the auxiliary drive system gears, when the electric drive receives excitation from the half-shaft or other components connected to the auxiliary drive system, the gears exhibit a strong nonlinear coupling vibration phenomenon of repeated contact, disengagement, and re-contact during meshing, leading to gear meshing squealing.

[0053] In related technologies, adjusting vehicle gear noise is mostly achieved by modifying the torque distribution between gears. For example, vehicle noise data is acquired, and the gear squeal values ​​of the front and rear reducers are determined based on this data, thereby determining the torque distribution between the front and rear electric drive systems. However, because the vehicle performs torque distribution in real time, the vehicle's range is reduced. Furthermore, existing technologies only consider the optimal torque distribution ratio between the front and rear electric drive systems at a constant vehicle speed, which has limitations and further reduces the vehicle's range.

[0054] In view of this, this application provides an electric drive whistling control method, which acquires the rotational noise of the vehicle's auxiliary drive system and the operating status of a target device in the vehicle. Based on the rotational noise of the auxiliary drive system and the operating status of the target device, it determines whether to apply torque to the vehicle's auxiliary drive system. The target device is a device that can affect the in-vehicle acoustic environment. It can be seen that the electric drive whistling control method provided in this application takes into account that when the in-vehicle acoustic environment is affected, the user is unlikely to perceive the whistling of the auxiliary drive system. Based on this, it determines whether to apply torque to the vehicle's auxiliary drive system, which can effectively reduce the number and duration of torque application by the auxiliary drive system during vehicle operation, thereby improving the vehicle's range without affecting the user's riding experience.

[0055] For ease of understanding, the electric drive whistling control method provided in this application will be described in detail below with reference to the accompanying drawings.

[0056] In some embodiments, such as Figure 1 As shown, the electric drive whistling control method provided in this application embodiment can be achieved through, as... Figure 1 The electric drive whistling control system shown includes a data acquisition unit 110, a processor 120, and an actuator 130. The data acquisition unit 110 is connected to the processor 120, and the processor 120 is connected to the actuator 130.

[0057] In some embodiments, the collector 110 includes a noise collector 1101 and a vehicle data collector 1102.

[0058] For example, noise collector 1101 is used to collect the rotational noise of the vehicle's auxiliary drive system and send it to processor 120.

[0059] For example, the noise collector 1101 can be a noise sensor.

[0060] For example, the vehicle data acquisition unit 1102 can communicate with the various electronic control units of the vehicle via a controller area network (CAN) bus to collect the vehicle's operating data and the working status of the target equipment in real time.

[0061] For example, the CAN bus is a highly reliable serial communication bus used in real-time applications. With its high reliability, real-time performance, and flexibility, the CAN bus forms an efficient information communication network within a vehicle, enabling various electronic control units to exchange data in real time.

[0062] The vehicle's operating data includes at least one of the following: vehicle speed, motor speed, motor torque, and accelerator pedal opening.

[0063] For example, the target device includes at least one of the following: a vehicle window, a speaker, an air conditioner, and a low-speed warning sound device.

[0064] The low-speed warning sound device can be a buzzer or an engine sound simulator, etc.

[0065] In some embodiments, the processor 120 is configured to determine whether to apply torque to the vehicle's auxiliary drive system. For example, the processor 120 is configured to acquire the rotational noise of the vehicle's auxiliary drive system and the operating state of the target device in the vehicle; based on the rotational noise of the vehicle's auxiliary drive system and the operating state of the target device in the vehicle, determine whether to apply torque to the vehicle's auxiliary drive system.

[0066] For example, the processor 120 can be any of the following: a server cluster consisting of multiple servers, a single server, a computer, or a processor or processing chip in a server or computer. This application does not limit this to any particular type.

[0067] In some embodiments, actuator 130 is used to apply torque to the vehicle's auxiliary drive system.

[0068] For example, actuator 130 may be a motor, hydraulic actuator, pneumatic actuator or electromagnetic actuator, etc.

[0069] It should be noted that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0070] Figure 2 This is a flowchart illustrating an electric drive squeal control method according to an exemplary embodiment, which is applied to, for example... Figure 1 The processor 120 in the middle, such as Figure 2 As shown, the electric drive whistling control method includes the following steps:

[0071] S201. Obtain the rotational noise of the vehicle's auxiliary drive system and the operating status of the vehicle's target equipment.

[0072] The target device is one that can affect the acoustic environment inside the vehicle.

[0073] In some embodiments, the target device includes at least one of the following: a vehicle window, a speaker, an air conditioner, and a low-speed warning sound device.

[0074] For example, the operating states of the target device include: on and off.

[0075] It should be noted that in relatively quiet in-car environments, the noise from the auxiliary drive system is more noticeable and more likely to affect the driving experience. When windows are open, external noise can enter the vehicle, significantly impacting the in-car acoustic environment. When windows are closed, external noise is blocked, minimizing its impact. Similarly, when speakers are on, playing music or navigation prompts, the in-car acoustic environment is significantly affected by the external sound. When speakers are off, the in-car acoustic environment is unaffected. Air conditioning, providing cooling or heating, generates noise that significantly impacts the in-car acoustic environment. When air conditioning is off, it produces no noise, and the in-car acoustic environment is unaffected. Finally, a low-speed warning sound may be emitted while the vehicle is in motion, significantly impacting the in-car acoustic environment. When the low-speed warning sound is off, the in-car acoustic environment is unaffected.

[0076] Understandably, by comprehensively considering multiple devices such as windows, speakers, air conditioning, and low-speed warning sounds, factors that can affect the vehicle's sound environment are taken into account, which can effectively reduce the possibility of applying torque to the auxiliary drive system and improve the vehicle's range.

[0077] In some embodiments, the auxiliary drive system is one or more auxiliary drive devices added in addition to the vehicle's original main drive system.

[0078] In some embodiments, rotational noise is used to represent the noise generated when the auxiliary drive system operates during vehicle operation.

[0079] S202. Based on the rotational noise of the auxiliary drive system and the operating status of the target equipment, determine whether to apply torque to the vehicle's auxiliary drive system.

[0080] In some embodiments, torque is applied to the vehicle's auxiliary drive system to reduce auxiliary drive system squeal. It is understood that applying torque to the vehicle's auxiliary drive system ensures that the contact surfaces in the drivetrain of the auxiliary drive system remain in a stable contact state, thereby reducing the squeal of the auxiliary drive system.

[0081] It should be noted that the rotational noise of the auxiliary drive system can be determined based on the rotational noise of the auxiliary drive system and the working status of the target device to determine whether the rotational noise of the auxiliary drive system will affect the driving comfort of the vehicle, and thus determine whether to apply torque to the vehicle's auxiliary drive system to reduce the whistling of the auxiliary drive system.

[0082] It should be understood that, when the torque is determined to be applied to the vehicle's auxiliary drive system, the target torque applied to the vehicle can be a constant value and will not change due to variations in rotational noise.

[0083] Understandably, compared to existing technologies where, in ECO mode, the rear-wheel drive drives the vehicle while the front-wheel drive only outputs minimal torque (i.e., pre-torque), thus reducing front-wheel drive whine, there is a problem where the front-wheel drive continuously outputs pre-torque, affecting the vehicle's range. This application employs a technique based on the target device's operating state and the follow-up noise of the auxiliary drive system to determine whether torque is being applied to the vehicle's auxiliary drive system. This effectively reduces the frequency and duration of torque application by the auxiliary drive system during vehicle operation, thereby improving the vehicle's range without affecting the user's riding experience.

[0084] As one possible implementation, step S201 can be implemented as follows: when the vehicle speed changes from the first speed range to the second speed range, the rotational noise of the auxiliary drive system and the working status of the target device are obtained.

[0085] In some embodiments, the vehicle speed is positively correlated with the rotational noise of the auxiliary drive system; for example, as the vehicle speed increases, the rotational noise of the auxiliary drive system increases.

[0086] For example, within the same speed range, the rotational noise of the auxiliary drive system has the same or similar impact on the in-vehicle acoustic environment.

[0087] For example, the rotational noise of the auxiliary drive system corresponding to the vehicle speed in the first speed range and the vehicle speed in the second speed range has a significant or moderate impact on the in-vehicle acoustic environment. The first speed range can be [30, 60) km / h, and the second speed range can be [60, 90) km / h, which can be divided according to actual conditions and is not limited in this application.

[0088] In some embodiments, the upper limit of the first speed range is less than the lower limit of the second speed range. It is understood that as vehicle speed increases, the vehicle speed transitions from the first speed range to the second speed range, increasing the follow-through noise of the auxiliary drive system. Furthermore, the operating state of the target device may change as the vehicle travels. Therefore, it is necessary to obtain the follow-through noise of the auxiliary drive system and the operating state of the target device to improve the accuracy of the electric drive whistling control method. For example, the first speed range can be [30, 60) km / h, and the second speed range can be [60, 90) km / h.

[0089] It should be understood that when the vehicle speed changes from the first speed range to the second speed range, the rate of change of the auxiliary drive system's rotational noise is relatively high. Furthermore, the operating state of the target equipment may change at the same time as the vehicle speed changes. Therefore, it is necessary to obtain the rotational noise of the auxiliary drive system and the operating state of the target equipment in order to improve the accuracy of the electric drive howling control method.

[0090] In other embodiments, the lower limit of the first speed range is greater than the upper limit of the second speed range. It is understood that as the vehicle speed decreases, the vehicle speed transitions from the first speed range to the second speed range, the follow-up noise of the auxiliary drive system decreases, and the operating state of the target device may change as the vehicle travels. Therefore, it is necessary to obtain the follow-up noise of the auxiliary drive system and the operating state of the target device to improve the accuracy of the electric drive whistling control method. The first speed range can be [60, 90) km / h, and the second speed range can be [30, 60) km / h.

[0091] It should be understood that as the noise of the auxiliary drive system decreases, the noise of the auxiliary drive system may not affect the in-vehicle acoustic environment. Therefore, it is necessary to reacquire the noise of the auxiliary drive system and the working status of the target device so as to change the torque of the auxiliary drive system in a timely manner and thus improve the vehicle's range.

[0092] As another possible implementation, step S201 above can also be implemented as: acquiring the rotational noise of the auxiliary drive system and the working status of the target device at preset time intervals.

[0093] In some embodiments, the preset time period is the time interval between two consecutive acquisitions of the follow-up noise of the auxiliary drive system and the operating state of the target device; alternatively, when it is determined that torque is to be added to the auxiliary drive system, the preset time period can be the time interval between two consecutive torque adjustments by the auxiliary drive system. The preset time period can be determined based on the vehicle's speed or performance, and this application does not limit the range of the preset time period.

[0094] For example, as the vehicle's driving time changes, the follow-up noise of the auxiliary drive system and the operating state of the target device may change. Therefore, it is necessary to obtain the follow-up noise of the auxiliary drive system and the operating state of the target device to improve the accuracy of the electric drive whistling control method. The preset time period can be 30 minutes.

[0095] For example, suppose the processor acquires the follow-up noise of the auxiliary drive system and the operating status of the target device at time t1. After a preset time period Δt during vehicle travel, i.e. at time t1+Δt, it acquires the follow-up noise of the auxiliary drive system and the operating status of the target device again. The preset time period Δt can be 30 minutes.

[0096] For example, suppose the processor adjusts the torque of the auxiliary drive system at time t1. After a preset time period Δt during vehicle operation, i.e., at time t1+Δt, the torque of the auxiliary drive system is released, and the follow-up noise of the auxiliary drive system and the operating status of the target device are acquired again. Based on the follow-up noise of the auxiliary drive system and the operating status of the target device, the torque to be applied to the auxiliary drive system is re-determined, and then the torque is applied to the auxiliary drive system. For example, the preset time period Δt can be 30 minutes.

[0097] As another possible implementation, step S201 above can also be implemented as: acquiring the rotational noise of the auxiliary drive system and the working status of the target device every time a preset distance is traveled.

[0098] In some embodiments, the preset driving distance is the distance the vehicle travels between two consecutive acquisitions of the assisted drive system's follow-up noise and the target device's operating state. Alternatively, when it is determined that torque is to be added to the assisted drive system, the preset driving distance can be the distance the vehicle travels between two consecutive torque adjustments in the assisted drive system. It can be determined based on the vehicle's speed; this application does not limit the magnitude of the preset driving distance.

[0099] For example, as the vehicle travels a certain distance, the following noise of the auxiliary drive system and the operating state of the target device may change. Therefore, it is necessary to obtain the following noise of the auxiliary drive system and the operating state of the target device to improve the accuracy of the electric drive howling control method.

[0100] For example, suppose the processor acquires the follow-up noise of the auxiliary drive system and the operating status of the target device when the vehicle travels to L1 km. After the vehicle has traveled a preset distance ΔL km, that is, at L1+ΔL km, it acquires the follow-up noise of the auxiliary drive system and the operating status of the target device again. Here, the preset distance ΔL can be 2.

[0101] For example, suppose the processor adjusts the torque of the assisted drive system when the vehicle travels to L1 km. After the vehicle has traveled a preset distance ΔL km, i.e., at L1+ΔL km, the processor releases the torque of the assisted drive system, and then acquires the follow-up noise of the assisted drive system and the operating status of the target device again. Based on the follow-up noise of the assisted drive system and the operating status of the target device, the processor redetermines the torque that needs to be applied to the assisted drive system, and then applies the torque to the assisted drive system. For example, the preset distance ΔL can be 2 km.

[0102] It should be understood that the period for acquiring the follow-up noise of the auxiliary drive system and the working status of the target equipment can be determined by setting a preset time period and a preset driving distance.

[0103] Understandably, by periodically acquiring the rotational noise of the auxiliary drive system and the working status of the target equipment based on vehicle speed, preset time period, or preset driving distance, the torque of the auxiliary drive system can be adjusted in a timely manner, thereby reducing the time when the vehicle applies torque and thus improving the vehicle's range.

[0104] In some embodiments, such as Figure 3 As shown, step S202 above can be implemented through any of the following steps:

[0105] S2021. When the target device is in the off state and the rotational noise of the auxiliary drive system is greater than the preset noise value, it is determined that torque is applied to the auxiliary drive system.

[0106] In some embodiments, the preset noise value is determined based on a preset correspondence between the vehicle's driving state and the preset noise value.

[0107] The preset correspondence is used to indicate the preset noise thresholds for different driving conditions. It should be noted that the preset correspondence is a set of noise thresholds pre-set during the vehicle's design based on its driving conditions.

[0108] For example, the preset noise value is used to represent the maximum rotational noise value that will not affect the driving experience under the current driving conditions. Based on the performance of the vehicle, this application does not limit the size of the preset noise value.

[0109] Understandably, by determining the preset noise value through the vehicle's driving state and the preset correspondence, the preset noise threshold can be judged in real time based on the vehicle's driving state. This allows for a more accurate determination of whether torque is applied to the auxiliary drive system, improving the accuracy of the electric drive whistling control method. Furthermore, this application is applicable to different vehicle driving states, enhancing the flexibility of the electric drive whistling control method.

[0110] In some embodiments, the vehicle's driving status is determined based on the vehicle's operating data.

[0111] For example, vehicle operating data includes at least one of the following: vehicle speed, motor speed, motor torque, and accelerator pedal opening.

[0112] Understandably, determining the vehicle's driving status in real time through its operating data allows for a more accurate assessment. Furthermore, the vehicle's operating data includes multiple factors such as vehicle speed, motor speed, motor torque, and accelerator pedal opening, providing a more comprehensive picture of the vehicle's driving status and thus improving the accuracy of the electric drive whistling control method.

[0113] In some embodiments, the vehicle's driving state may be ECO mode, sport mode, or idling. For example, when the vehicle speed is zero or close to zero and the motor speed and torque are low, the vehicle is in an idling state.

[0114] It should be noted that when the vehicle is in ECO mode, the vehicle prioritizes energy saving and low noise, so the preset noise level can be relatively low to ensure that the vehicle remains quiet in a low-power state. When the vehicle is in Sport mode, the preset noise threshold may be moderately increased as the vehicle's performance improves. When the vehicle is idling, the preset noise level can be set lower to improve the driving experience when the vehicle is stationary or moving slowly.

[0115] Understandably, when the target device is off and the rotational noise of the auxiliary drive system is greater than the preset noise value, applying torque to the auxiliary drive system can effectively control the whistling of the auxiliary drive system and improve the driving comfort of the vehicle.

[0116] S2022. If the rotational noise of the auxiliary drive system is less than or equal to a preset noise value, determine that no torque is applied to the auxiliary drive system.

[0117] It should be noted that when the rotational noise of the auxiliary drive system is less than or equal to the preset noise value, the rotational noise of the auxiliary drive system will not affect the sound environment inside the vehicle. Therefore, it will not affect the driving experience of the vehicle, and torque does not need to be applied to the auxiliary drive system.

[0118] S2023. If the rotational noise of the auxiliary drive system is greater than the preset noise value and the target device is in the on state, determine that no torque is applied to the auxiliary drive system.

[0119] It should be noted that when the target device is turned on, it will affect the in-vehicle acoustic environment. At this time, when the rotational noise of the auxiliary drive system is greater than the preset noise value, the impact of the rotational noise of the auxiliary drive system on the in-vehicle acoustic environment is much smaller than the impact of the target device on the in-vehicle acoustic environment. Therefore, it will not affect the driving experience of the vehicle, and torque does not need to be applied to the auxiliary drive system.

[0120] Understandably, by determining that the target device is in the off state and the rotational noise of the auxiliary drive system is greater than the preset noise value, applying torque to the auxiliary drive system can effectively control the whistling of the auxiliary drive system and improve the driving comfort of the vehicle. At the same time, when the target device is in the on state or the rotational noise of the auxiliary drive system is less than or equal to the preset noise value, the whistling of the auxiliary drive system is not easily detected, and torque can be left unapplied to the auxiliary drive system. This can improve the vehicle's range without affecting the user's riding experience.

[0121] In some embodiments, such as Figure 4 As shown, after determining that torque is applied to the vehicle's auxiliary drive system, the electric drive whistling control method provided in this application further includes the following steps:

[0122] S401. Under the condition that the preset conditions are met, stop applying torque to the auxiliary drive system.

[0123] In some embodiments, the preset conditions include at least one of the following:

[0124] Condition 1: After applying torque to the auxiliary drive system, the vehicle speed changes from the first speed range to the second speed range.

[0125] It should be understood that when the vehicle speed changes from the first speed range to the second speed range, the follow-up noise of the auxiliary drive system and the working state of the target equipment may change. Therefore, it is necessary to first cancel the torque of the auxiliary drive system and then re-determine whether to apply torque to the auxiliary drive system.

[0126] Condition 2: After applying torque to the auxiliary drive system, the vehicle travels a distance greater than or equal to a preset distance.

[0127] It should be understood that when the vehicle's travel distance is greater than or equal to the preset distance, the rotational noise of the auxiliary drive system and the working state of the target equipment may change. Therefore, it is necessary to first cancel the torque of the auxiliary drive system and then re-determine whether to apply torque to the auxiliary drive system.

[0128] Condition 3: After applying torque to the auxiliary drive system, the vehicle travels for a time greater than or equal to a preset time.

[0129] It should be understood that when the vehicle's driving time is greater than or equal to the preset time, the following noise of the auxiliary drive system and the working state of the target equipment may change. Therefore, it is necessary to first cancel the torque of the auxiliary drive system and then re-determine whether to apply torque to the auxiliary drive system.

[0130] Understandably, by setting preset conditions, and stopping the application of torque to the auxiliary drive system when these conditions are met, the torque of the auxiliary drive system can be canceled based on real-time changes in vehicle speed, driving distance, or driving time during vehicle operation, thereby improving the vehicle's range.

[0131] In some embodiments, such as Figure 5 As shown, when it is determined that torque is applied to the vehicle's auxiliary drive system, the electric drive whistling control method provided in this application further includes the following steps:

[0132] S501, The target torque value applied by the auxiliary drive system is determined based on the rotational noise of the auxiliary drive system.

[0133] In some embodiments, the target torque value may be determined based on a large number of experiments.

[0134] It should be understood that determining the target torque value includes: selecting a smooth test road, collecting various vehicle operating data on the selected road surface, collecting the rotational noise, and adjusting it in real time to the magnitude of the torque applied by the auxiliary drive system, comparing the whistling results of the auxiliary drive system to determine the target torque value to be applied. The test road can be a performance road at a test track, etc.; the vehicle operating data can include at least one of the following: vehicle speed, motor speed, motor torque, and accelerator pedal opening.

[0135] It should be noted that the following noise of the auxiliary drive system is positively correlated with the target torque value. For example, as the following noise of the auxiliary drive system increases, the target torque value that needs to be applied to the auxiliary drive system needs to increase.

[0136] It is understandable that by determining the rotational noise of the auxiliary drive system as the target torque value applied by the auxiliary drive system, the optimal torque applied by the auxiliary drive system can be determined, thereby maximizing the vehicle's range.

[0137] Figure 6 This is a flowchart illustrating yet another electric drive whistling control method according to an exemplary embodiment, such as... Figure 6 As shown, the electric drive whistling control method includes the following steps:

[0138] S601. Acquire the following noise of the vehicle's auxiliary drive system, the vehicle's operating data, and the working status of the vehicle's target equipment.

[0139] For example, the target device is a device that can affect the acoustic environment inside a vehicle.

[0140] The target equipment includes at least one of the following: vehicle, speaker, air conditioner, and low-speed warning sound device.

[0141] S602. Determine whether the target device is in the powered-on state.

[0142] For example, if the target device is in the on state, proceed to step S604; if the target device is in the off state, proceed to step S603.

[0143] S603. Determine whether the following noise of the auxiliary drive system is greater than the preset noise value.

[0144] For example, if the following noise of the auxiliary drive system is greater than a preset noise value, the process jumps to step S607; if the following noise of the auxiliary drive system is less than or equal to the preset noise value, the process jumps to step S604.

[0145] S604, Determine not to apply torque to the auxiliary drive system.

[0146] S605. Determine whether the vehicle speed has transitioned from the first speed range to the second speed range.

[0147] For example, if the vehicle speed changes from the first speed range to the second speed range, the process jumps to step S601; if the vehicle speed does not change from the first speed range to the second speed range, the process jumps to step S606.

[0148] S606. Determine whether the vehicle has traveled through a preset time period or a preset distance.

[0149] For example, after the vehicle has traveled for a preset time period or a preset distance, the process jumps to step S601; if the vehicle has not traveled for the preset time period or a preset distance, the process jumps to step S604.

[0150] S607, determined to apply torque to the auxiliary drive system.

[0151] S608. Determine whether the preset conditions are met.

[0152] For example, if the preset conditions are met, proceed to step S609; if the preset conditions are not met, proceed to step S607.

[0153] The preset conditions include at least one of the following: after applying torque to the auxiliary drive system, the vehicle speed changes from the first speed range to the second speed range; after applying torque to the auxiliary drive system, the vehicle travels a distance greater than or equal to a preset distance; after applying torque to the auxiliary drive system, the vehicle travels for a time greater than or equal to a preset time.

[0154] S609. Stop applying torque to the auxiliary drive system.

[0155] For example, after stopping the application of torque to the auxiliary drive system, the process jumps to step S601.
