Description

Technical Field

[0001] This disclosure relates to the field of intelligent vehicle technology, and in particular to a range extender control method, apparatus, device, and computer-readable storage medium. Background Technology

[0002] Currently, the new energy vehicle industry is booming, with various new car manufacturers emerging one after another. However, the overall technical solutions remain unchanged, with electric vehicles as the main focus, while other technologies are not yet mature enough. For electric vehicles, different car companies have adopted different technical routes, including pure electric vehicles, plug-in hybrid electric vehicles, and range-extended electric vehicles.

[0003] Range-extended electric vehicles (REEVs) are electric vehicles equipped with both ground charging and onboard power supply capabilities. REEVs are increasingly favored for their flexible power supply options, simple structure, energy efficiency, and emission reduction. Since the range extender is a crucial component of a REEV, its control strategy significantly impacts its performance and, consequently, the overall performance of the REEV.

[0004] However, due to the constraints of noise, vibration, and harshness (NVH) performance, the operating point of the range extender is controlled within a certain range during the calibration process, resulting in a low energy conversion rate of the range extender and increased vehicle energy consumption. Summary of the Invention

[0005] To address the aforementioned technical problems, this disclosure provides a range extender control method, apparatus, device, and computer-readable storage medium to improve the operating power of the range extender, thereby increasing the energy conversion efficiency of the range extender and reducing vehicle energy consumption.

[0008] Based on the working data, the noise data in the cockpit is separated to obtain environmental noise data, which is the noise data transmitted from the external environment to the cockpit.

[0009] Based on the environmental noise data, the target operating power of the range extender is found from the preset operating power relationship table;

[0010] The operation of the range extender is controlled according to the target operating power.

[0031] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0033] This disclosure provides a range extender control method, which will be described below with reference to specific embodiments.

[0034] Figure 1 This is a flowchart illustrating a range extender control method provided in an embodiment of this disclosure. This method can be applied to scenarios where the operating power of the range extender is increased without altering NVH performance, thereby improving the energy conversion efficiency of the range extender. It is understood that the range extender control method provided in this disclosure can also be applied to other scenarios.

[0035] The following is about Figure 1 The control method for the range extender shown is described below, and the specific steps of this method are as follows:

[0036] S101. Acquire noise data in the cockpit and operating data of the range extender, wherein the operating data of the range extender includes the frequency and intensity of the noise emitted by the range extender during operation.

[0037] Electronic devices acquire noise data from the cockpit and operating data from the range extender. Cockpit noise data includes the intensity and frequency of noises such as music, wind noise, tire noise, and range extender noise. Range extender operating data includes the intensity and frequency of the sound emitted by the range extender.

[0038] S102. Based on the working data, the noise data is separated to obtain environmental noise data, which is the noise data transmitted from the external environment to the cockpit.

[0039] After acquiring noise data from the cockpit and operating data from the range extender, the electronic equipment separates the cockpit noise data based on the range extender's operating data, obtaining ambient noise data. Specifically, a noise extraction algorithm model can be used to separate the cockpit noise data into range extender noise data and ambient noise data. Ambient noise data includes the intensity and frequency of noises other than range extender noise, such as music, wind noise, and tire noise. Range extender noise data can include the frequency and intensity of the range extender noise.

[0040] S103. Based on the environmental noise data, find the target operating power of the range extender from the preset operating power relationship table.

[0041] The electronic device looks up the target operating power of the range extender corresponding to the current ambient noise data from a preset operating power relationship table.

[0042] In some embodiments, the electronic device determines the target operating power of the range extender based on a preset correspondence table between environmental noise data and the operating power of the range extender.

[0043] For example, after obtaining the current ambient noise data, the target operating power of the range extender corresponding to the current ambient noise data is determined. The correspondence between the ambient noise data and the operating power of the range extender can be a one-to-one curve relationship, which is not limited here.

[0044] S104. Control the operation of the range extender according to the target operating power.

[0045] After determining the target operating power of the range extender, the range extender can be controlled to operate based on the target operating power and the overall vehicle operating conditions. The target operating power is the maximum operating power of the range extender without affecting NVH performance.

[0046] Specifically, S104 may include, but is not limited to, steps S1041 and S1042:

[0047] S1041. Based on the correspondence between the rotational speed of the range extender and the operating power of the range extender, and the target operating power of the range extender, determine the target rotational speed of the range extender.

[0048] S1042. Adjust the speed of the range extender according to the target speed of the range extender, and control the speed of the range extender to reach the target speed of the range extender.

[0049] This embodiment of the disclosure acquires noise data from the cockpit and operating data from the range extender. The operating data includes the frequency and intensity of noise emitted by the range extender during operation. The noise data is then separated based on the operating data to obtain environmental noise data, which is the noise transmitted from the external environment to the cockpit. Further, based on the environmental noise data, the target operating power of the range extender is retrieved from a preset operating power relationship table. The operation of the range extender is then controlled according to the target operating power. Since the target operating power of the range extender is retrieved from the preset operating power relationship table based on the current environmental noise data, and the operation of the range extender is further controlled according to the target operating power, the target operating power is the maximum operating power of the range extender without affecting NVH performance. This increases the operating power of the range extender, thereby improving the energy conversion efficiency of the range extender and reducing the vehicle's energy consumption.

[0050] Based on the above embodiments, the acquisition of noise data in the cockpit and operating data of the range extender includes: acquiring noise data in the cockpit collected by the audio acquisition device, and acquiring operating data of the range extender collected by the vibration sensor on the range extender.

[0051] When acquiring noise data within the cockpit and operating data of the range extender, the electronic equipment acquires noise data from the audio acquisition device and operating data from the vibration sensor on the range extender. The audio acquisition device is used to collect noise data within the cockpit, and the vibration sensor is used to collect operating data from the range extender. Cockpit noise data includes the intensity and frequency of noises such as music, wind noise, tire noise, and range extender noise. Range extender operating data includes the intensity and frequency of sounds emitted by the range extender.

[0052] Optionally, the operating data of the range extender includes the frequency of the range extender noise.

[0053] The operating data of the range extender includes the frequency of the range extender noise, the intensity of the sound emitted by the range extender, and may also include other data when the range extender is operating.

[0054] Accordingly, the noise data is separated based on the working data to obtain environmental noise data, including: separating the noise data based on the frequency of the range extender noise to obtain environmental noise data.

[0055] After acquiring noise data from the cockpit collected by the audio acquisition device and operating data from the range extender collected by the vibration sensor on the range extender, the electronic equipment separates the noise data according to the frequency (or spectrum) of the range extender noise, thus obtaining ambient noise data. Ambient noise data includes the intensity and frequency of noises other than range extender noise, such as music, wind noise, and tire noise. Range extender noise data can include the frequency and intensity of the range extender noise.

[0056] This embodiment of the disclosure acquires noise data from the cockpit collected by an audio acquisition device and operating data from the range extender collected by a vibration sensor on the range extender. The operating data of the range extender includes the frequency of the range extender noise. The noise data is separated based on the frequency of the range extender noise to obtain environmental noise data. By utilizing the noise data from the cockpit collected by the audio acquisition device and the operating data from the range extender collected by the vibration sensor, environmental noise data can be obtained, further determining the target operating power of the range extender. This allows for increasing the operating power of the range extender without affecting NVH performance, thereby improving the energy conversion efficiency of the range extender and reducing vehicle energy consumption.

[0057] Figure 2 A flowchart of a range extender control method provided in another embodiment of this disclosure is shown below. Figure 2 As shown, the method includes the following steps:

[0058] S201. Acquire noise data in the cockpit and operating data of the range extender, wherein the operating data of the range extender includes the frequency and intensity of the noise emitted by the range extender during operation.

[0059] Specifically, the implementation process and principle of S201 and S101 are the same, and will not be repeated here.

[0060] S202. Based on the working data, the noise data is separated to obtain environmental noise data, which is the noise data transmitted from the external environment to the cockpit.

[0061] Specifically, the implementation process and principle of S202 and S102 are the same, and will not be repeated here.

[0062] S203. The maximum value of the environmental noise data is taken as the target intensity of the range extender noise.

[0063] For example, after obtaining the current ambient noise data, the target intensity of the range extender noise is determined, where the target intensity of the range extender noise is the maximum value of the ambient noise.

[0064] Optionally, the masking effect of sound (other sounds in the same environment can reduce a listener's hearing of a particular sound) can be used to determine the relationship between the range extender noise data and the ambient noise data. Specifically, the relationship between the range extender noise data and the ambient noise data is such that the intensity of the range extender noise is less than the intensity of the ambient noise, i.e., the decibel level of the range extender noise is less than the decibel level of the ambient noise. In this case, the range extender noise will be masked by the ambient noise. Further, based on the relationship between the range extender noise data and the ambient noise data, a target intensity of the range extender noise is determined. The electronic device determines the target intensity of the range extender noise based on the current ambient noise intensity. The target intensity of the range extender noise is the maximum value of the ambient noise; that is, when the intensity of the range extender noise is the target intensity, the range extender noise can be masked by the ambient noise and will not affect NVH performance.

[0065] S204. Based on the preset correspondence table between the intensity of the range extender noise and the operating power of the range extender, determine the target operating power of the range extender corresponding to the target intensity of the range extender noise.

[0066] For example, after determining the target noise level of the range extender, the target operating power of the range extender corresponding to the target noise level is determined. The correspondence between the noise level and the operating power of the range extender can be a one-to-one curve relationship, which is not limited here. Optionally, the correspondence between the noise level and the operating power of the range extender can be a correspondence obtained through multiple monitoring by the user, or it can be a correspondence provided by the manufacturer.

[0067] S205. Determine the control power of the range extender based on the target operating power and the vehicle power, wherein the vehicle power is the current discharge power of the vehicle.

[0068] The control power of the range extender is determined based on the target operating power and the vehicle's current discharge power. The target operating power is only used as a maximum limit; the control power of the range extender is determined based on the overall vehicle power and the target operating power.

[0069] In some embodiments, the vehicle power can be determined based on the current SOC of the vehicle battery, and then the control power of the range extender can be determined based on the target operating power and the vehicle power.

[0070] Specifically, S205 may include, but is not limited to, steps S2051 and S2052:

[0071] S2051. If the total vehicle power is less than the target operating power, then the control power of the range extender is the total vehicle power.

[0072] When the vehicle's current discharge power is less than the target operating power, the range extender's control power is the vehicle's current discharge power.

[0073] S2052. If the total vehicle power is greater than or equal to the target operating power, then the control power of the range extender is the target operating power.

[0074] When the vehicle's current discharge power is greater than or equal to the target operating power, the control power of the range extender is the target operating power.

[0075] S206. Control the operation of the range extender according to the control power of the range extender.

[0076] After determining the control power of the range extender, the range extender is controlled to operate according to the control power of the range extender.

[0077] Optionally, the range extender can be controlled to operate at the target torque and target speed according to the target torque and target speed of the range extender corresponding to the control power of the range extender.

[0078] This embodiment of the disclosure acquires noise data from the cockpit and operating data of the range extender. The noise data is then separated based on the operating data to obtain ambient noise data. The maximum value of the ambient noise data is then used as the target intensity of the range extender noise. Further, based on a preset correspondence table between range extender noise intensity and range extender operating power, the target operating power of the range extender corresponding to the target noise intensity is determined. Then, based on the target operating power and the vehicle power (where the vehicle power is the vehicle's current discharge power), the control power of the range extender is determined, and the range extender is controlled to operate according to this control power. Since the control power of the range extender is determined based on the target operating power and the vehicle power, and the range extender is then controlled to operate at the control power, the limitations of the target operating power and the vehicle power are met. In this case, the energy conversion rate of the range extender is high, and energy consumption is low. Moreover, it does not affect NVH performance, resulting in a better user experience.

[0079] Figure 3 A flowchart of a range extender control method provided in another embodiment of this disclosure is shown below. Figure 3 As shown, the method includes the following steps:

[0080] S301. Acquire noise data in the cockpit collected by the audio acquisition device, and acquire operating data of the range extender collected by the vibration sensor on the range extender.

[0081] The electronic device acquires noise data from the cockpit collected by the audio acquisition device, and operational data from the range extender collected by the vibration sensor on the range extender. The audio acquisition device is used to collect noise data from the cockpit, and the vibration sensor is used to collect operational data from the range extender. Cockpit noise data includes the intensity and frequency of noises such as music, wind noise, tire noise, and range extender noise. Range extender operational data includes the intensity and frequency of sounds emitted by the range extender.

[0082] S302. The noise data is separated according to the frequency of the range extender noise to obtain environmental noise data, which is the noise data transmitted from the external environment to the cockpit.

[0083] Specifically, the implementation process and principle of S302 and S202 are the same, and will not be repeated here.

[0084] S303. The maximum value of the environmental noise data is taken as the target intensity of the range extender noise.

[0085] Specifically, the implementation process and principle of S303 and S203 are the same, and will not be repeated here.

[0086] S304. Based on the preset correspondence table between the noise intensity of the range extender and the operating power of the range extender, determine the target operating power of the range extender corresponding to the target noise intensity of the range extender.

[0087] Specifically, the implementation process and principle of S304 and S204 are the same, and will not be repeated here.

[0088] S305. Determine the control power of the range extender based on the target operating power and the vehicle's required power, wherein the vehicle's required power is the power required for the vehicle's current operating conditions.

[0089] The control power of the range extender is determined based on the target operating power and the power required by the vehicle under current operating conditions. The target operating power is only a maximum limit; the control power of the range extender is determined based on the overall vehicle power requirement and the target operating power.

[0090] In some embodiments, the decision to control the range extender to operate based on a target power output can be determined based on the vehicle's trip distance, which can be derived from navigation or predicted. When the energy required for the vehicle's trip exceeds the vehicle's current State of Charge (SOC), controlling the range extender to operate based on the target power output further enhances the user experience.

[0091] Specifically, S305 may include, but is not limited to, steps S3051 and S3052:

[0092] S3051. If the required power of the vehicle is less than the target operating power, then the control power of the range extender is the required power of the vehicle.

[0093] When the power required by the vehicle under current operating conditions is less than the target operating power, the control power of the range extender is the power required by the vehicle under current operating conditions.

[0094] S3052. If the required power of the vehicle is greater than or equal to the target operating power, then the control power of the range extender is the target operating power.

[0095] When the power required by the vehicle under the current operating conditions is greater than or equal to the target operating power, the control power of the range extender is the target operating power.

[0096] S306. Control the operation of the range extender according to the control power of the range extender.

[0097] After determining the control power of the range extender, the range extender is controlled to operate according to the control power of the range extender.

[0098] Optionally, the range extender can be controlled to operate at the target torque and target speed according to the target torque and target speed of the range extender corresponding to the control power of the range extender.

[0099] Specifically, the electronic device determines the target speed of the range extender corresponding to the control power of the range extender based on the correspondence between the range extender's rotational speed and its operating power; and determines the target torque of the range extender corresponding to its control power based on the correspondence between the range extender's torque and its operating power.

[0100] Optionally, the relationship between the range extender's speed and its operating power, and the relationship between its torque and its operating power, can be a relationship obtained through multiple monitoring sessions by the user, or a relationship provided by the manufacturer. Specifically, the relationship between the range extender's speed and its operating power can be a positive correlation curve.

[0101] Furthermore, the electronic device adjusts the speed and torque of the range extender according to the target speed and target torque of the range extender, controlling the range extender to operate at the target speed and target torque. At this time, the energy conversion rate of the range extender is high and the energy consumption is low. This embodiment of the disclosure acquires noise data in the cockpit collected by an audio acquisition device and operating data of the range extender collected by a vibration sensor on the range extender. The noise data is separated according to the frequency of the range extender noise to obtain environmental noise data, which is the noise data transmitted from the external environment to the cockpit. Then, the maximum value of the environmental noise data is taken as the target intensity of the range extender noise. Further, according to a preset correspondence table between the intensity of the range extender noise and the operating power of the range extender, the target operating power of the range extender corresponding to the target intensity of the noise is determined. Then, based on the target operating power and the vehicle's required power, the control power of the range extender is determined, where the vehicle's required power is the power required under the current operating conditions of the vehicle. The range extender is controlled to operate according to the control power of the range extender. By separating the noise data based on the frequency of the range extender noise to obtain environmental noise data, the intensity and frequency of the range extender noise and the ambient noise can be calculated using noise data collected in the cockpit by an audio acquisition device and operating data of the range extender collected by vibration sensors on the range extender. Then, the target intensity of the range extender noise and the target operating power of the range extender corresponding to the target noise intensity are determined. Further, based on the target operating power and the vehicle's required power, the control power of the range extender is determined. The range extender is then controlled to operate at the control power, meeting the limitations of the target operating power and the vehicle's required power. This allows for increased operating power of the range extender without affecting NVH performance, thereby improving the range extender's energy conversion rate, reducing vehicle energy consumption, and improving the user experience.
