Fig. 1 is a flowchart of a cooling method of a vehicle-mounted wireless charging device according to an embodiment of the present application. The cooling method of the vehicle-mounted wireless charging device can be suitable for controlling the cooling device on the vehicle to cool the vehicle-mounted wireless charging device by controlling the cooling device, for example, the cooling device of the vehicle-mounted mobile phone wireless charging device by controlling a fan. The method may be performed by a cooling device of the in-vehicle wireless charging apparatus, which may be integrated in the in-vehicle wireless charging apparatus by software and/or hardware. As shown in fig. 1, the cooling method of the vehicle-mounted wireless charging device provided in the embodiment includes the following steps:

s110, acquiring current vehicle operation information of the target vehicle, wherein the current vehicle operation information is related to the environmental noise of the target vehicle.

In the present embodiment, in order to realize the cooling device control based on the environmental noise by covering the cooling noise of the cooling device with the environmental noise, it is necessary to acquire the current vehicle operation information associated with the environmental noise of the target vehicle. Wherein the ambient noise of the target vehicle may include at least one of ambient device noise and ambient operating noise.

Specifically, the environmental device noise may be noise generated when a device mounted on the target vehicle is operated, for example, noise generated when an air conditioner is operated. The environmental operation noise may be noise generated by the operation of the target vehicle, such as noise generated by vibration of the vehicle on the road surface during traveling, noise generated by friction between the tire and the road surface, noise generated between the air flow and the vehicle body, and the like.

In the present embodiment, it is considered that the operation of the air conditioner may cause the environmental device noise, and the magnitude of the air conditioner gear is correlated with the magnitude of the environmental device noise of the target vehicle, for example, the larger the air conditioner gear, the larger the environmental device noise. And, considering that the vehicle running may cause the environmental operation noise, the magnitude of the vehicle speed or the vehicle jolt state is correlated with the magnitude of the environmental operation noise of the target vehicle, for example, the faster the vehicle speed or the higher the vehicle jolt degree, the greater the environmental operation noise.

Thus, the current vehicle operation information may include at least one of a current air-conditioner gear, a current vehicle speed, and a current vehicle bump state. Wherein the current air-conditioner gear is associated with ambient device noise of the target vehicle, and the current vehicle speed and the current vehicle bump state are associated with ambient operating noise of the target vehicle. The current vehicle jounce state may be used to describe whether the target vehicle is running jounce and, in the case of running jounce, the degree of jounce of the vehicle.

S120, determining a target input voltage duty ratio of a cooling device in the target vehicle based on the current vehicle running information, and controlling the cooling device to cool the vehicle-mounted wireless charging device in the target vehicle according to the target input voltage duty ratio so as to cover cooling noise of the cooling device through environmental noise.

In the present embodiment, after the current vehicle operation information of the target vehicle is acquired, the operation control of the cooling apparatus may be implemented based on the current vehicle operation information. Specifically, the target input voltage duty ratio of the cooling device may be determined through the current vehicle operation information, so that operation control of the cooling device is achieved by controlling the input voltage duty ratio of the cooling device.

The cooling device can be a device for cooling the vehicle-mounted wireless charging device, such as a fan; the in-vehicle wireless charging device may be a device that wirelessly charges a terminal such as a mobile phone, a tablet computer, or the like.

The target input voltage duty cycle may be a proportion of the on-time of the input voltage of the cooling device to the entire period. The magnitude of the target input voltage duty cycle is related to the operating power of the cooling device and determines the cooling performance of the cooling device. Specifically, the larger the duty ratio of the target input voltage is, the larger the running power of the cooling device is, and the stronger the cooling performance of the vehicle-mounted wireless charging device is.

Taking cooling equipment as a fan as an example, the larger the target input voltage duty ratio is, the larger the rotating speed of the fan is, the higher the cooling efficiency is, and the stronger the heat dissipation effect on the vehicle-mounted wireless charging equipment is; the smaller the target input voltage duty ratio is, the smaller the rotating speed of the fan is, the lower the cooling efficiency is, and the weaker the heat dissipation effect on the vehicle-mounted wireless charging equipment is.

In one example, considering that the vehicle speed and the vehicle bump state are associated with the ambient operation noise of the vehicle, the cooling noise of the cooling apparatus may be covered by the ambient operation noise. Accordingly, determining the target input voltage duty cycle of the cooling device in the target vehicle based on the current vehicle operation information may be: and obtaining the target input voltage duty ratio based on the preset duty ratio corresponding to the current vehicle speed or the preset duty ratio corresponding to the current vehicle bump state.

The higher the current vehicle speed is, the larger the corresponding preset duty ratio is; the higher the current bump degree of the current vehicle bump state description, the larger the corresponding preset duty cycle.

By the method, the cooling equipment can be controlled to work at a larger target input voltage duty ratio under the condition of higher vehicle speed or higher jolt degree so as to properly improve the operation power of the cooling equipment when the environment operation noise is larger, and the cooling equipment can be controlled to work at a smaller target input voltage duty ratio under the condition of lower vehicle speed or lower jolt degree so as to properly reduce the operation power of the cooling equipment when the environment operation noise is smaller, thereby realizing the real-time control of the operation of the cooling equipment, reducing the perception of noise generated by a user on the cooling equipment through the environment operation noise and ensuring the heat dissipation effect of the vehicle-mounted wireless charging equipment.

In another example, considering that the air-conditioning gear is associated with the ambient device noise of the vehicle, the cooling noise of the cooling apparatus may be covered by the ambient device noise. Accordingly, determining the target input voltage duty cycle of the cooling device in the target vehicle based on the current vehicle operation information may be: and determining a target input voltage duty cycle of the cooling equipment based on the preset duty cycle corresponding to the current air-conditioner gear.

The higher the current air-conditioner gear is, the larger the corresponding preset duty ratio is. By the mode, the cooling equipment can be controlled to work at a larger target input voltage duty ratio under the condition that the air conditioner gear is higher so as to properly improve the operation power of the cooling equipment when the noise of the environmental device is larger, and the cooling equipment can be controlled to work at a smaller target input voltage duty ratio under the condition that the air conditioner gear is lower so as to properly reduce the operation power of the cooling equipment when the noise of the environmental device is smaller, thereby realizing the real-time control of the operation of the cooling equipment, reducing the noise perception of a user on the cooling equipment through the noise of the environmental device and ensuring the heat dissipation effect of the vehicle-mounted wireless charging equipment.

According to the method provided by the embodiment, the current vehicle operation information related to the environmental noise of the target vehicle is obtained, the target input voltage duty ratio of the cooling equipment is determined according to the current vehicle operation information, the cooling equipment is controlled to cool the vehicle-mounted wireless charging equipment based on the target input voltage duty ratio, so that the environmental noise is used for controlling the operation of the cooling equipment through the environmental noise in the vehicle operation process, the cooling noise of the cooling equipment is covered, the cooling equipment can be operated with the larger input voltage duty ratio when the environmental noise of the vehicle is large, and the cooling equipment can be operated with the smaller input voltage duty ratio when the environmental noise of the vehicle is small, the purpose of reducing noise perception of a user on the cooling equipment through the environmental noise of the vehicle is achieved, the trouble of the noise of the cooling equipment to the user is further reduced, the noise problem of the cooling equipment is solved while the charging speed of the vehicle-mounted wireless charging equipment is solved, and the user experience is improved.

For the manner of determining the target input voltage duty ratio based on the current air-conditioner gear in the above embodiment, considering that the driving device also affects the noise of the environmental device of the vehicle when the vehicle is running, the target input voltage duty ratio can be obtained by combining the driving mode of the target vehicle at the current moment on the basis of the noise, so as to further improve the control accuracy of the cooling device.

Referring to fig. 2, fig. 2 is a flowchart of another cooling method of an on-vehicle wireless charging device according to an embodiment of the present application, which illustrates a specific implementation of determining a target input voltage duty ratio in combination with a current driving mode and a current air-conditioner gear. Referring to fig. 2, the method includes the steps of:

s210, acquiring current vehicle operation information of the target vehicle, wherein the current vehicle operation information is related to the environmental noise of the target vehicle, and comprises a current driving mode and a current air-conditioner gear.

In the present embodiment, it is considered that the driving device in the vehicle may affect the environmental device noise of the vehicle in addition to the environmental device noise of the vehicle. For example, the ambient device noise caused by engine driving is greater than the ambient device noise caused by motor driving. Thus, the current drive mode and the current air-conditioner shift position of the target vehicle can be acquired.

The current driving mode can be motor driving, engine driving or common driving of an engine motor; the common driving of the engine and the motor may be simultaneous driving of the engine and the motor. The current drive mode may be determined according to a vehicle type of the target vehicle, for example, for a pure electric vehicle, the current drive mode may be motor drive, and for a hybrid electric vehicle, the current drive mode may be engine motor co-drive.

S220, determining a target input voltage duty ratio according to the current driving mode, the current air-conditioner gear and a preset cooling strategy.

In this embodiment, according to the current driving mode, the current air-conditioner gear and the preset cooling strategy, the target input voltage duty ratio is determined in the following two ways:

in a first manner, the preset cooling strategy may include each air-conditioning gear and an input voltage duty cycle corresponding to each driving mode. Specifically, the input voltage duty ratio corresponding to the current driving mode and the current air-conditioner gear can be queried from a preset cooling strategy to obtain a target input voltage duty ratio;

in the second mode, the preset cooling strategy may include a preset duty ratio corresponding to each air-conditioning gear, and the preset cooling strategy corresponding to each driving mode may be different. Specifically, a corresponding preset cooling strategy can be determined through the current driving mode, and then a preset duty ratio corresponding to the current air-conditioner gear is queried in the corresponding preset cooling strategy, so that a target input voltage duty ratio is obtained.

In view of the second manner described above, in a specific embodiment, the preset cooling strategy includes a first cooling strategy and a second cooling strategy; determining a target input voltage duty cycle according to the current drive mode, the current air-conditioner gear and a preset cooling strategy, including: if the current driving mode is engine driving or engine motor co-driving, determining a target input voltage duty ratio according to the current air-conditioner gear and a first cooling strategy; or if the current driving mode is motor driving, determining a target input voltage duty ratio according to the current air-conditioner gear and a second cooling strategy, wherein the corresponding environmental noise of the engine driving or the common driving of the engine and the motor is larger than the corresponding environmental noise of the motor driving.

In this embodiment, considering that the magnitude of the noise of the environmental apparatus caused by the motor drive is different from that of the engine drive, for example, the engine drive or the engine motor co-drive is larger than that of the motor drive, a corresponding first cooling strategy may be set for the engine drive or the engine motor co-drive, and a corresponding second cooling strategy may be set for the motor drive.

Specifically, a driving mode with engine participation, such as engine driving or engine motor co-driving, may determine the target input voltage duty ratio according to the first cooling strategy and the current air-conditioner gear, and a driving mode with engine not participation, such as motor driving, may determine the target input voltage duty ratio according to the second cooling strategy and the current air-conditioner gear.

It should be noted that, for the same air-conditioner gear, the target input voltage duty cycle determined in conjunction with the first cooling strategy may be greater than the target input voltage duty cycle determined in conjunction with the second cooling strategy.

The determining the target input voltage duty ratio according to the first cooling strategy and the current air-conditioner gear, and the determining the target input voltage duty ratio according to the second cooling strategy and the current air-conditioner gear may be: obtaining a corresponding target input voltage duty ratio based on the current air conditioner gear inquiry through the corresponding relation described by the first cooling strategy or the second cooling strategy; or, the corresponding noise value can be obtained by calculating the current air-conditioner gear based on the calculation mode described by the first cooling strategy or the second cooling strategy, and then the corresponding target input voltage duty ratio is obtained through the noise value.

In the former way, specifically, in one example, determining the target input voltage duty cycle according to the current air-conditioner gear and the first cooling strategy includes: taking a first preset duty ratio corresponding to the current air-conditioner gear in a first cooling strategy as a target input voltage duty ratio;

determining a target input voltage duty cycle according to the current air-conditioner gear and a second cooling strategy, comprising: and taking a second preset duty ratio corresponding to the current air-conditioner gear in a second cooling strategy as a target input voltage duty ratio.

The first cooling strategy may describe a preset duty cycle corresponding to each air-conditioning gear, and the second cooling strategy may describe a preset duty cycle corresponding to each air-conditioning gear. For example, the first cooling strategy and the second cooling strategy may include preset duty ratios corresponding to the respective air-conditioner gear positions; or, the first cooling strategy and the second cooling strategy may include preset duty ratio ranges corresponding to the respective air-conditioner gear ranges.

Specifically, if the first cooling strategy and the second cooling strategy include preset duty ratios corresponding to the respective air-conditioner gear positions, the corresponding preset duty ratios can be directly queried from the first cooling strategy through the current air-conditioner gear position. If the first cooling strategy and the second cooling strategy comprise preset duty ratio ranges corresponding to the respective duty ratio ranges, the corresponding preset duty ratio ranges can be obtained by inquiring the first cooling strategy or the second cooling strategy according to the current duty ratio range, and then the preset duty ratio corresponding to the current duty ratio range is obtained by interpolation in the preset duty ratio range corresponding to the preset duty ratio range according to the maximum gear and the minimum gear corresponding to the preset duty ratio range.

Exemplary, the first cooling strategy includes: the first preset duty ratio corresponding to the OFF, first gear and second gear is 50%; the first preset duty ratio corresponding to the third gear, the fourth gear and the fifth gear is 60% -70%; the first preset duty ratio corresponding to the sixth gear, the seventh gear and the eighth gear is 70% -80%. The second cooling strategy includes: the second preset duty ratio corresponding to the OFF, first gear and second gear is 40%; the second preset duty ratio corresponding to the third gear, the fourth gear and the fifth gear is 50% -60%; the second preset duty ratio corresponding to the sixth gear, the seventh gear and the eighth gear is 60% -80%.

In the above example, by taking the first preset duty ratio corresponding to the current air-conditioning gear in the first cooling strategy or the second cooling strategy as the target input voltage duty ratio, the operation control of the cooling device based on the air-conditioning gear in different driving modes is realized.

S230, controlling the cooling device according to the target input voltage duty ratio to cool the vehicle-mounted wireless charging device in the target vehicle so as to cover cooling noise of the cooling device through ambient noise.

According to the cooling method of the vehicle-mounted wireless charging equipment, provided by the embodiment, the driving mode, the air conditioner gear and the preset cooling strategy of the vehicle can be realized by considering the noise association of the driving device of the vehicle and the environment device of the air conditioner and the vehicle, the control accuracy of the cooling equipment is further improved, the cooling noise of the cooling equipment is ensured to be covered by the noise of the driving device and the environment device generated by the air conditioner, the running power of the cooling equipment can be improved as much as possible, and the cooling efficiency of the vehicle-mounted wireless charging equipment is further improved.

In addition to the above-described determination of the target input voltage duty cycle based on the current air-conditioner gear and the current drive mode, the ambient operating noise may be further considered to cover the cooling noise of the cooling apparatus in combination with the ambient operating noise and the ambient device noise.

As shown in fig. 3, fig. 3 is a flowchart of another cooling method of the vehicle-mounted wireless charging device according to the embodiment of the present application. The method is characterized in that on the basis of determining a target input voltage duty ratio based on a current air-conditioner gear and a current driving mode, the target input voltage duty ratio is further corrected by combining a current vehicle speed and a current vehicle bump state, so that the operation control of cooling equipment combining environment operation noise and environment device noise is realized. Referring to fig. 3, the cooling method of the vehicle-mounted wireless charging device includes the steps of:

S310, acquiring current vehicle running information of a target vehicle, and determining a target input voltage duty ratio according to a current driving mode, a current air-conditioner gear and a preset cooling strategy.

The current vehicle operation information comprises a current driving mode, a current air-conditioner gear, a current vehicle speed and a current vehicle bump state. Specifically, the current drive mode and the current air-conditioner gear are associated with the environmental device noise of the target vehicle; the current vehicle jounce state and the current vehicle speed are correlated to the ambient operating noise of the target vehicle.

S320, determining a duty ratio correction amount of the cooling equipment according to the current vehicle speed and the current vehicle bump state, and correcting the duty ratio of the target input voltage based on the duty ratio correction amount.

The current vehicle bump state may be determined based on the wheel speed signal, or may be determined based on the gradient of the current traveling section of the target vehicle in the navigation information.

Specifically, the target input voltage duty ratio may be determined based on the current driving mode, the current air-conditioner gear, and a preset cooling strategy, and then corrected according to the current vehicle speed and the current vehicle bump state. Wherein the duty cycle correction amount may be a duty cycle that is increased on the basis of the target input voltage duty cycle.

In some embodiments, determining a duty cycle correction amount for the cooling apparatus based on the current vehicle speed and the current vehicle jounce state includes: determining a first correction amount of the cooling device according to the current vehicle speed, and determining a second correction amount of the cooling device according to the current vehicle bump state; the maximum value of the first correction amount and the second correction amount is determined as the duty correction amount.

Specifically, a correction amount may be determined based on the current vehicle speed and the current vehicle bump state, respectively. The first correction amount and the second correction amount may be determined according to a preset cooling strategy for the determination of the correction amounts.

Illustratively, determining the first correction amount and the second correction amount in combination with the preset cooling strategy may be performed in two ways: the corresponding relation described by the preset cooling strategy can be used for respectively inquiring and obtaining a first correction amount and a second correction amount based on the current vehicle speed and the current vehicle bump state; alternatively, the first correction amount and the second correction amount may be calculated based on the current vehicle speed and the current vehicle bump state, respectively, by a calculation method described by a preset cooling strategy.

In a manner of determining the correction amount based on the correspondence relation, for the determination of the first correction amount, in a specific embodiment, the determination of the first correction amount of the cooling apparatus according to the current vehicle speed includes: determining a current vehicle speed range corresponding to the current vehicle speed; and determining a first correction amount based on a first preset correction value corresponding to the current vehicle speed range.

The preset cooling strategy may further include a first preset correction value corresponding to each vehicle speed range. Specifically, a current vehicle speed range corresponding to a current vehicle speed may be determined first, and then, a first correction amount may be determined according to a first preset correction value corresponding to the current vehicle speed range in a preset cooling strategy.

According to the embodiment, the vehicle speed range can be determined first, and then the corresponding first correction amount is obtained through vehicle speed range inquiry, so that the duty ratio correction based on the vehicle speed is realized, the control accuracy of the cooling equipment is further ensured by combining the environmental operation noise on the basis of controlling the cooling equipment according to the noise of the environmental device.

In a manner of determining the correction amount based on the correspondence relation, for the determination of the second correction amount, in a specific embodiment, the determination of the second correction amount of the cooling apparatus according to the current vehicle jounce state includes: judging whether the target vehicle runs to jolt or not according to the current jolt state of the vehicle; if yes, determining a second correction amount according to the current bumping degree corresponding to the current bumping state of the vehicle and a second preset correction value.

The preset cooling strategy may include a second preset correction value corresponding to each of the bump degrees. Specifically, whether the target vehicle runs to jolt or not can be judged according to the current jolt state of the vehicle, if yes, a second preset correction value corresponding to the current jolt degree is further queried according to a preset cooling strategy, and the second correction value is obtained.

According to the embodiment, whether the target vehicle runs and jolts can be judged first, the corresponding second correction amount is further obtained through inquiring the current jolts degree under the condition of running and jolts, the duty ratio correction based on the jolts state of the vehicle is realized, the environment running noise is combined on the basis of controlling the cooling equipment according to the noise of the environment device, and the control accuracy of the cooling equipment is further ensured.

In the above-described process of determining the first correction amount and the second correction amount based on the preset cooling strategy, the first correction amount and the second correction amount may also be determined using the first cooling strategy if the current driving mode is engine driving or engine motor co-driving, otherwise, the first correction amount and the second correction amount may be determined using the second cooling strategy.

After the first correction amount and the second correction amount are obtained, the maximum value of the first correction amount and the second correction amount may be further used as a duty ratio correction amount to correct the target input voltage duty ratio, thereby obtaining a final target input voltage duty ratio. For example, the duty cycle correction amount is added to the target input voltage duty cycle to obtain the final target input voltage duty cycle.

The first correction amount and the second correction amount are obtained through the current vehicle speed and the current vehicle bump state respectively, and then the maximum value in the first correction amount and the second correction amount is adopted to update the duty ratio of the target input voltage, so that the duty ratio correction based on the vehicle speed and the vehicle bump state can be realized, the purpose of further adjusting the duty ratio of the cooling equipment by combining the environment operation noise is achieved, the cooling noise of the cooling equipment is covered by the environment noise, the operation power of the cooling equipment is improved as much as possible, and the heat dissipation effect of the cooling equipment is improved.

It is to be understood that, instead of using the maximum value as the duty correction amount, the average value of the first correction amount and the second correction amount may be used as the duty correction amount; alternatively, either one of the first correction amount and the second correction amount may be selected as the duty correction amount.

S330, controlling the cooling device according to the target input voltage duty ratio to cool the vehicle-mounted wireless charging device in the target vehicle so as to cover cooling noise of the cooling device through ambient noise.

According to the cooling method for the vehicle-mounted wireless charging equipment, the duty cycle correction amount of the cooling equipment is determined through the current vehicle speed and the current vehicle bump state, and then the target input voltage duty cycle is corrected according to the duty cycle correction amount, so that the characteristic that the vehicle speed and the vehicle bump state are related to the environment operation noise is considered, the influence of the environment operation noise is further considered on the basis of determining the duty cycle of the cooling equipment according to the environment device noise, the duty cycle is adjusted, the control of the cooling equipment combining the environment device noise and the environment operation noise is achieved, and the heat dissipation effect of the cooling equipment on the vehicle-mounted wireless charging equipment is improved as much as possible while the perception of the cooling noise of the cooling equipment by a user is reduced.

In this embodiment, a charging flow of the in-vehicle wireless charging device will be described using a cooling device as an example of a fan. As shown in fig. 4, fig. 4 is a charging flowchart of a vehicle-mounted wireless charging device provided in an embodiment of the present application. First, after detecting that the vehicle is powered ON, a switch of HUT (Human-Computer Interaction, human-computer interaction system) state may be detected, and if the switch is OFF, WPC (Wireless Power Charging, wireless charging) is not operated, and if the switch is ON, foreign matter monitoring or charging area deviation recognition and main and sub driving door state monitoring are performed.

Specifically, if a foreign object is detected or a deviation of the charging area is identified, an alarm prompt is made. If the primary and secondary gate status is monitored to be OPEN (OPEN), the WPC is not operational. Further, under the conditions that no foreign matter is detected, no deviation of a charging area is detected, and a main driving door and a secondary driving door are Closed (Closed), public and private charging protocols are identified, and then a terminal (such as a mobile phone, a tablet personal computer, a smart watch and the like) can be charged through the vehicle-mounted wireless charging equipment, and the cooling equipment starts to work.

Fig. 5 is a schematic diagram of a process for determining a duty cycle according to an embodiment of the present application. As shown in fig. 5, taking a fan as an example, a process of determining a target input voltage duty ratio according to a first preset strategy in the case of engine driving or engine motor co-driving is illustrated.

Specifically, when the driving mode of the target vehicle is engine driving or the engine and the motor are jointly driven, the noise in the vehicle is larger than that of the motor driving, and the vehicle-mounted wireless charging equipment can further identify the air quantity gear of the vehicle air conditioner. When the air quantity gear of the air conditioner is OFF, first gear and second gear, the noise of an environmental device is low, the environment is quiet, the noise of the cooling equipment working at the moment is lower in working state, namely the running power of the cooling equipment is lower, meanwhile, the heat dissipation effect needs to be considered, and on the premise of not influencing the heat dissipation effect, the smaller voltage duty ratio of the input voltage duty ratio of the cooling equipment at the moment, namely the duty ratio of the fan voltage is 50%, can be determined;

further, the vehicle speed signal can be continuously identified, if the current vehicle speed is less than or equal to 0km/h and less than or equal to 10km/h, the environment in the vehicle is quiet, and at the moment, the cooling equipment can keep a smaller voltage value in a working state, namely the duty ratio of the fan voltage is kept to be 50%; if the current speed is less than or equal to 30km/h and more than 10km/h is met, the environment in the vehicle is quite quiet, the noise of the fan working can be similar to or less than the environment noise in the vehicle, the power of the cooling equipment can be properly adjusted, the cooling effect is compatible, and on the premise that the cooling effect is not affected, the duty ratio of the input voltage of the cooling equipment can be increased by 10% -20%, namely, the duty ratio of the voltage of the cooling equipment can be adjusted to be 60% -70%; if the current speed of the vehicle is more than 30km/h, the environmental noise is larger, the working noise of the cooling equipment can be properly increased, the power of the cooling equipment is increased, the input voltage of the cooling equipment is adjusted, the duty ratio of the input voltage of the cooling equipment can be increased by 20-30%, and the duty ratio of the voltage of the cooling equipment can be adjusted between 70-80%.

In addition to the above identification of the vehicle speed signal, the wheel speed signal may be identified. The wheel speed signal and the vehicle speed signal may be related to each other, that is, the vehicle speed signal may be acquired or the wheel speed signal may be acquired, or the vehicle speed signal and the wheel speed signal may be acquired at the same time. In fig. 5, the vehicle-mounted wireless charging device can judge the bump state of the vehicle through the wheel speed signal by taking the vehicle speed signal and the wheel speed signal as an example, and the wheel speed signal can be used as compensation for the vehicle speed signal because the bump of the vehicle greatly increases the environmental operation noise, when the serious bump of the vehicle is recognized through the wheel speed signal, the environmental operation noise is larger, the working noise of the cooling device can be properly increased at the moment, the duty ratio of the input voltage of the cooling device can be adjusted, the duty ratio of the input voltage can be increased by 0-30%, namely, the duty ratio of the input voltage can be adjusted between 50% and 80%. Since the wheel speed signal is compensated for the vehicle speed signal, the duty ratio of the input voltage of the cooling device therebetween can be maximized.

When the air-conditioner gear is three gears, four gears and five gears, the vehicle environment is quite quiet, and the duty ratio of the input voltage of the cooling equipment can be adjusted between 60% and 70%. Further, the vehicle speed signal and the wheel speed signal are identified, and according to different vehicle speeds and wheel speed signals, the duty ratio of the input voltage of the cooling equipment can be increased by 0-20%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted between 60% and 80%.

When the air-conditioner gear is six gears, seven gears and eight gears, the noise of the environment in the vehicle is larger, and the duty ratio of the input voltage of the cooling equipment can be adjusted between 70% and 80%. Further, the vehicle speed signal and the wheel speed signal are identified, and according to different vehicle speeds and wheel speed signals, the duty ratio of the input voltage of the cooling equipment can be increased by 0-10%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted between 70% and 80%.

Fig. 6 is a schematic diagram of another duty cycle determination process according to an embodiment of the present application. As shown in fig. 6, taking a fan as an example, a process of determining a target input voltage duty ratio according to a second preset strategy in the case of motor driving is illustrated.

Specifically, when the driving mode of the target vehicle is motor driving, the noise in the vehicle is small, the vehicle-mounted wireless charging device can identify the air volume gear of the vehicle air conditioner, when the air volume gear of the air conditioner is OFF, first gear and second gear, the environment in the vehicle is quiet, the noise of the cooling device working at the moment is the smallest noise in the working state, the rotating speed is smallest, namely the running power of the cooling device is smallest, meanwhile, the heat dissipation effect is considered, and on the premise of not influencing the heat dissipation effect, the input voltage value of the cooling device is the smallest voltage value in the working state, namely the duty ratio of the input voltage of the cooling device is 40%.

The vehicle-mounted wireless charging equipment can continuously identify a vehicle speed signal, and if the current vehicle speed is less than or equal to 0km/h and less than or equal to 10km/h, the environment in the vehicle is quiet, and at the moment, the cooling equipment keeps the minimum voltage value in the working state, namely the duty ratio of the input voltage of the cooling equipment is kept unchanged by 40%; if the current speed of 10km/h is less than or equal to 30km/h, the environment in the vehicle is quite quiet, the noise of the cooling equipment working is similar to or less than the environment in the vehicle, the power of the cooling equipment can be properly adjusted, the heat dissipation effect is compatible, and on the premise of not influencing the heat dissipation effect, the duty ratio of the input voltage of the cooling equipment can be increased by 10% -20%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted to be 50% -60%; if the current speed of the vehicle is more than 30km/h, the noise in the vehicle is larger, the working noise of the cooling equipment can be properly increased, the running power of the cooling equipment can be increased, the input voltage of the cooling equipment is adjusted, the duty ratio of the input voltage of the cooling equipment can be increased by 20% -40%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted between 60% -80%.

When the vehicle speed signal is identified, the vehicle wireless charging equipment can also identify the wheel speed signal, the vehicle bumping state is judged through the wheel speed signal, when the serious bumping of the vehicle is identified through the wheel speed signal, the noise in the vehicle is large, the working noise of the cooling equipment can be properly increased, the input voltage of the cooling equipment is adjusted, the duty ratio of the input voltage of the cooling equipment can be increased by 0-40%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted to be between 40% and 80%.

When the air-conditioner gear is three gears, four gears and five gears, the vehicle environment is quite quiet, and the duty ratio of the input voltage of the cooling equipment can be adjusted to be 50% -60%. Further, the vehicle speed signal and the wheel speed signal are identified, and according to different vehicle speeds and wheel speed signals, the duty ratio of the input voltage of the cooling equipment can be increased by 0-30%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted between 50% and 80%.

When the air-conditioner gear is six gears, seven gears and eight gears, the noise of the environment in the vehicle is larger, and the duty ratio of the input voltage of the cooling equipment can be adjusted to be 60-80%. Further, the vehicle speed signal and the wheel speed signal are identified, and according to different vehicle speeds and wheel speed signals, the duty ratio of the input voltage of the cooling equipment can be increased by 0-20%, namely, the duty ratio of the input voltage of the cooling equipment can be adjusted between 60% and 80%. In the case of a fan, the duty ratio of the input voltage of the cooling device is not more than 80% at maximum.
