[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. To make the technical solutions and advantages of the present application clearer, the noise control method, device, and device will be described in detail below in conjunction with the drawings.

[0047] Figure 1 Shows a flowchart of a vehicle control method for generating electricity using ambient pressure provided by an embodiment of the present application. This method can be applied to a piezoelectric power generation system. As Figure 1 shown, the method includes the following steps:

[0048] S101. Obtain environmental data and vehicle operating status data.

[0049] Among them, the environmental data includes the pressure - facing angles and pressure - facing values at various positions of the vehicle body under the current vehicle operating status, and the vehicle operating data includes vehicle speed and vehicle body attitude.

[0050] S102. Adjust the vehicle operating status according to the environmental data and vehicle operating status data.

[0051] By adjusting the vehicle operating status, the environmental pressure acting on the vehicle body can be changed to maximize the power generation efficiency of the vehicle body power generation system.

[0052] The vehicle control method provided by the embodiment of the present application can detect the environmental data in the vehicle's surrounding environment in real - time, and the controller actively adjusts the vehicle's operating status, so that the piezoelectric power generation system can maximize the conversion of the environmental pressure acting on the vehicle body surface into electricity, thereby using the energy in the surrounding environment to provide energy for the vehicle - mounted battery, and further reducing the energy consumption loss of the vehicle itself and improving the vehicle's energy economy.

[0053] The following describes the piezoelectric power generation system for executing the above - mentioned vehicle control method. As Figure 2 and Figure 3 shown, the piezoelectric power generation system may include an environmental perception sensor 2 and a controller 1. Figure 1 The vehicle control method shown in

[0054] can be specifically executed by the controller 1 in the piezoelectric power generation system.

[0055] Among them, the environmental perception sensor 2 can be used to obtain environmental data and send the obtained environmental data to the controller 1.

[0056] The environmental perception sensors 2 can be distributed at intervals and fixed at various positions of the vehicle body 4 to fully detect the environmental data of the environment around the vehicle body 4. The energies with higher utilization efficiency in the surrounding environment are wind energy and rain energy. Therefore, the environmental perception sensor 2 can include a rain sensor, a wind speed and direction sensor, or a combination of a rain sensor and a wind speed and direction sensor.

[0057] Alternatively, the raindrop direction can be calculated by combining rain sensors at multiple angles to detect the raindrop sizes in different angular directions. The rain sensor can be a capacitive or infrared scattering type. The capacitive rain sensor can determine the rainfall amount by detecting the change in capacitance value when raindrops fall between the gates of the capacitor. The infrared scattering rain sensor can emit infrared rays and determine the rainfall amount by detecting the scattering of light by raindrops.

[0058] The wind speed and direction sensor can obtain the wind speed and direction. In some embodiments, the wind speed and direction can be directly obtained by a wind speed and direction sensor. Alternatively, a wind sensor and a direction sensor can be combined to obtain the wind speed and direction. In some embodiments, the wind sensor can be a mechanical wind speed sensor or an ultrasonic wind speed sensor, etc. The mechanical wind speed sensor is pushed by the wind force generated by air flow to rotate the sensor, and then drives the internal sensing element to generate a pulse signal, and the wind speed is calculated based on the linear relationship between the wind speed and the pulse frequency. The ultrasonic wind speed sensor calculates the wind speed by calculating the time difference of the transmission of ultrasonic waves between two points. The direction sensor can be a photoelectric direction sensor or a voltage type direction sensor, etc. The photoelectric direction sensor uses the photoelectric signal conversion principle to determine the direction information. The voltage type direction sensor outputs the corresponding direction information through a voltage signal.

[0059] The controller 1 in the piezoelectric power generation system can obtain the environmental data acquired and sent by the environmental perception sensor 2, and the controller 1 can also obtain the vehicle operation state data from various sensors built in the vehicle. Furthermore, the controller 1 can adjust the vehicle operation state according to the environmental data and the current vehicle operation information to maximize the power generation efficiency of the vehicle body 4 power generation system. The controller 1 can be an independent controller independently set corresponding to the piezoelectric power generation system, or the controller 1 can be integrated on any controller of the whole vehicle.

[0060] As Figure 2 and Figure 3 shown, the piezoelectric power generation system may further include a piezoelectric power generation unit 7, and the piezoelectric power generation unit 7 can convert the pressure acting thereon into electricity. In some embodiments, the piezoelectric power generation unit 7 can be made of piezoelectric materials, including organic piezoelectric materials, inorganic piezoelectric materials, and composite piezoelectric materials, etc. If pressure is applied to the piezoelectric material, the pressure material will generate a potential difference, thereby converting the pressure into electricity.

[0061] The piezoelectric power generation unit 7 can be electrically connected to the vehicle-mounted battery 3 to store the electric energy generated by the piezoelectric power generation unit 7 into the vehicle-mounted battery 3. The vehicle-mounted battery 3 can be any one of a high-voltage battery or a low-voltage battery. Correspondingly, different processing circuits, such as a rectifying circuit, etc., can be electrically connected between the piezoelectric power generation unit 7 and the vehicle-mounted battery 3.

[0062] In addition, one or more switching elements may be electrically connected between the piezoelectric power generation unit 7 and the vehicle-mounted battery 3 to disconnect the electrical connection between the piezoelectric power generation unit 7 and the vehicle-mounted battery 3 when charging the vehicle-mounted battery 3 is not required.

[0063] The piezoelectric power generation unit 7 may be directly connected to the vehicle body 4, and the attitude of the piezoelectric power generation unit 7 itself is adjustable. For example, both the tilt angle and the tilt direction of the piezoelectric power generation unit 7 relative to the position of the vehicle body 4 where it is located are adjustable. In some embodiments, a plurality of piezoelectric power generation units 7 with different directions or angles may be arranged on the vehicle body 4, and then the controller 1 can adjust only the tilt angle or the tilt direction of each piezoelectric power generation unit 7. The attitude of the piezoelectric power generation unit 7 can be adjusted, for example, by a cylinder or a motor drive.

[0064] Furthermore, as Figure 2 、 Figures 4A - 4B and Figure 5 shown, the piezoelectric power generation system may further include a pressure regulating unit 5. Similar to the above-mentioned piezoelectric power generation unit 7, the attitude of the pressure regulating unit 5 is adjustable. The attitude of the pressure regulating unit 5 includes the tilt angle, the tilt direction, and the combination of the tilt angle and the tilt direction of the pressure regulating unit 5. The attitude of the pressure regulating unit 5 can be adjusted, for example, by a cylinder or a motor drive.

[0065] In the present application, both the tilt angle and the tilt direction are relative to the vehicle body at the position where the corresponding unit is located. Exemplarily, the tilt angle may be the horizontal included angle between the piezoelectric power generation unit 7 (pressure regulating unit 5) and the vehicle body at the position where it is located; the tilt direction may be the orientation of the piezoelectric power generation unit 7 (pressure regulating unit 5) in the direction of the vertical line around the vehicle body at the position where it is located.

[0066] Similar to the environmental sensor, the pressure regulating unit 5 and / or the piezoelectric power generation unit 7 may be distributed at various positions of the vehicle body 4 at intervals. In some embodiments, the pressure regulating unit 5 and / or the piezoelectric power generation unit 7 may be provided on the surface of the vehicle body 4, for example, attached to the surface of the vehicle body 4 in a bonding manner. Alternatively, the pressure regulating unit 5 and / or the piezoelectric power generation unit 7 may also be provided inside the vehicle and close to the surface of the vehicle body 4. For example, the pressure regulating unit 5 and / or the piezoelectric power generation unit 7 may be provided between the vehicle frame and the skin. In this case, the skin on the surface of the vehicle body 4 may have a certain deformation ability to allow the shape of the surface of the vehicle body 4 to be changed when the attitude of the pressure regulating unit 5 and / or the piezoelectric power generation unit 7 changes, thereby changing the pressure receiving angle and the pressure receiving value at various positions of the vehicle body 4.

[0067] According to different installation methods or positions, the pressure regulating unit 5 included in the piezoelectric power generation system may be classified into a first pressure regulating unit and a second pressure regulating unit. Among them, asFigure 4A and Figure 4B As shown in Figure 4B , the pressure regulating unit 5 (the first pressure regulating unit) and the piezoelectric power generation unit 7 can be independently located on the vehicle body 4, and the first pressure regulating unit can be used to adjust the direction of the air flow 6 flowing through the piezoelectric power generation unit 7.

[0068] Figure 4A and Figure 4B In Figure 4B , an example is shown where each pressure regulating unit 5 corresponds to one piezoelectric power generation unit 7. In other embodiments, as shown in Figure 5 Figure 5 each pressure regulating unit 5 can also correspond to multiple piezoelectric power generation units 7.

[0069] In this case, one or more piezoelectric power generation units 7 can be arranged behind the pressure regulating unit 5 (i.e., on the side away from the vehicle head) to maximize the influence of the pressure regulating unit 5 changing the direction of the air flow 6 on the piezoelectric power generation unit 7.

[0070] Furthermore, as shown in Figure 6 Figure 6 the pressure regulating unit 5 (the second pressure regulating unit) can be located between the piezoelectric power generation unit 7 and the vehicle body 4 and connected to the piezoelectric power generation unit 7, and the second pressure regulating unit can be used to adjust the attitude of the piezoelectric power generation unit 7. In some embodiments, the piezoelectric power generation unit 7 can be fixed to the pressure regulating unit 5 in a bonded form.

[0071] In the embodiments of the present application, a plurality of first pressure regulating units and a plurality of second pressure regulating units can be arranged on the vehicle body 4, and the first pressure regulating unit and the second pressure regulating unit can be arranged at intervals or crosswise. The first pressure regulating unit and the second pressure regulating unit can change the shape of the surface of the vehicle body 4 (the surface of the vehicle body 4 includes the surface of the pressure regulating unit 5 or the piezoelectric power generation unit 7) through different mechanisms, and thus can adjust the ambient pressure 8 acting on the piezoelectric power generation unit 7, improving the flexibility of the arrangement of the pressure regulating unit 5.

[0072] The controller 1 can independently control the pressure regulating units 5 and the piezoelectric power generation units 7 at various positions of the vehicle body 4, so as to adjust the attitude of each pressure regulating unit 5 and / or piezoelectric power generation unit 7 specifically. In some embodiments, one pressure regulating unit 5 and one or more corresponding piezoelectric power generation units 7 around it can form a sub-power generation system, and a plurality of sub-power generation systems can be arranged at intervals on the vehicle body 4. In other embodiments, the piezoelectric power generation system may not have a pressure regulating unit 5, and each sub-power generation system may include one or more piezoelectric power generation units 7 within a certain area range. The controller 1 can independently control each sub-power generation system.

[0073] Further, each pressure regulating unit 5 and its corresponding piezoelectric power generation unit 7 may be adjacent to or corresponding to one or more environmental perception sensors 2. In other words, each sub-power generation system may further include an environmental perception sensor 2 within a certain area range of the pressure regulating unit 5 in the sub-power generation system. This area range may be preset by the manufacturer.

[0074] The controller 1 may store the identifiers of the pressure regulating unit 5, the piezoelectric power generation unit 7, and the environmental perception sensor 2 corresponding to each subsystem. Furthermore, the controller 1 may adjust the posture of the pressure regulating unit 5 or the piezoelectric power generation unit 7 according to the environmental data obtained by the environmental perception sensor 2 in the same subsystem to improve the accuracy of control.

[0075] In addition, the connection control between the controller 1 and the environmental perception sensor 2, the pressure regulating unit 5, the piezoelectric power generation unit 7, and the vehicle-mounted battery 3 may be harness connection control or wireless communication connection control. The control power supply for the controller 1, the environmental perception sensor 2, the pressure regulating unit 5, the piezoelectric power generation unit 7, and the vehicle-mounted battery 3 may be harness power supply or wireless power supply.

[0076] Figure 7 The flowchart of another vehicle control method using ambient pressure to generate electricity is shown, and this method can be applied to the above-mentioned piezoelectric power generation system. As Figure 7 shown, this method includes the following steps:

[0077] S701. Obtain the battery status data of the vehicle-mounted battery.

[0078] The controller may obtain the battery status data of the vehicle-mounted battery in real time from the sensor provided on the vehicle-mounted battery. This battery status data may at least include the remaining power and the operation data, where the operation data can be used to indicate the working state of the battery. In some embodiments, the operation data may at least include the fault information of the vehicle-mounted battery.

[0079] The controller may determine whether the vehicle-mounted battery can operate normally according to the operation data of the vehicle-mounted battery, and determine whether the vehicle-mounted battery needs to be charged based on the remaining power of the vehicle-mounted battery. When the controller confirms that the vehicle-mounted battery can operate normally and the remaining voltage is lower than the power threshold, it is considered that the vehicle-mounted battery can be charged.

[0080] In the embodiments of the present application, the vehicle-mounted battery may include a low-voltage battery and a high-voltage battery. For these two different types of batteries, the corresponding power thresholds may be different.

[0081] S702. In response to the battery status data satisfying the charging condition, determine the maximum allowable charging efficiency according to the battery status data.

[0082] In the embodiments of the present application, the charging condition may include that the vehicle-mounted battery is operating normally and the remaining power is lower than the power threshold. In some embodiments, the power threshold may be determined to be 100%, 95%, 90%, 85% or 80% etc. of the full charge of the vehicle-mounted battery.

[0083] The controller may also pre-store the correspondence between the power range of the remaining power and the allowed maximum charging efficiency. When the controller determines that the vehicle-mounted battery needs to be charged based on the battery status data, the controller may determine which power range the current remaining power falls into. That is, the controller may determine the allowed maximum charging efficiency of the vehicle-mounted battery based on the remaining power and the correspondence between the power range of the remaining power and the allowed maximum charging efficiency.

[0084] S703. Obtain environmental data and vehicle operation status data.

[0085] The environmental perception sensor may obtain the environmental data around the vehicle in real time. Or when the controller confirms that the vehicle-mounted battery needs to be charged, the controller instructs the environmental perception sensor to start obtaining the environmental data.

[0086] In response to the battery status data satisfying the charging condition, the controller may obtain the environmental data and the vehicle operation status data from the environmental sensor. The order between this step S703 and the above step S702 is not limited in the present application. In some embodiments, this step S703 may be executed simultaneously with the above step S702. In other embodiments, step S703 may be executed before or after the above step S702.

[0087] Specifically, the environmental perception sensor may be a rain sensor, and the rain sensor is configured to obtain the raindrop impact speed and the raindrop impact direction. The controller may determine the corresponding pressure value of the piezoelectric power generation unit according to the raindrop impact speed. The pressure value can be used to characterize the magnitude of the environmental pressure received by the piezoelectric power generation unit. And the controller may determine the pressure angle according to the raindrop impact direction, and the pressure angle can be used to characterize the acting direction of the environmental pressure received by the piezoelectric power generation unit.

[0088] Or, the environmental perception sensor may be a wind speed and direction sensor, and the wind speed and direction sensor is configured to obtain the wind speed and the wind direction. The controller may determine the pressure value according to the wind speed and determine the pressure angle according to the wind direction.

[0089] In other words, the piezoelectric power generation system includes at least one of a rain sensor and a wind speed and direction sensor; obtaining environmental data includes: determining the pressure value according to at least one of the raindrop impact speed and the wind speed; determining the pressure angle according to at least one of the raindrop impact direction and the wind direction.

[0090] In addition, the controller in the piezoelectric power generation system can also be signal-connected to various sensors built in the vehicle, and thus can obtain vehicle operation state data from other sensors. The vehicle operation state data can at least include vehicle speed and vehicle body attitude. In the embodiments of the present application, the vehicle body attitude of the vehicle can be determined according to the tire angles of the vehicle, and the tire angles refer to the deflection angles of the tires at various positions of the vehicle relative to the vehicle body.

[0091] S704. Adjust the vehicle operation state and / or the attitude of the pressure regulation unit according to the environmental data, the vehicle operation state data, and the maximum charging efficiency.

[0092] The controller can determine whether the current vehicle is in a stationary state or a moving state according to the obtained vehicle speed. In the case where the piezoelectric power generation system does not include a pressure regulation unit, when the vehicle is in a stationary state, the controller can change the environmental pressure acting on the piezoelectric power generation unit by adjusting the vehicle body attitude; when the vehicle is in a moving state, the controller can change the environmental pressure acting on the piezoelectric power generation unit by adjusting the vehicle speed.

[0093] In the case where the piezoelectric power generation system includes a pressure regulation unit, when the vehicle is in a stationary state, the controller can change the environmental pressure acting on the piezoelectric power generation unit by adjusting the vehicle body attitude and the attitude of the pressure regulation unit; when the vehicle is in a moving state, the controller can change the environmental pressure acting on the piezoelectric power generation unit by adjusting the vehicle speed and the attitude of the pressure regulation unit.

[0094] In the embodiments of the present application, the vehicle body attitude can be adjusted by adjusting the deflection angles of the wheels.

[0095] Exemplarily, the controller can adjust the vehicle operation state and the attitude of the pressure regulation unit based on the principles shown in the following table.

[0096]

[0097] As Figure 4A and Figure 4B shown, when the pressure regulation unit and the piezoelectric power generation unit are independently located on the vehicle body, the pressure regulation unit can change the direction of the airflow flowing through the nearby piezoelectric power generation unit by adjusting its own tilt angle and tilt direction. As Figure 6 shown, when the pressure regulation unit is located between the piezoelectric power generation unit and the vehicle body and is connected to the piezoelectric power generation unit, the pressure regulation unit can adjust the attitude of the piezoelectric power generation unit to which it is connected by adjusting its own tilt angle and tilt direction.

[0098] The layout positions of each pressure regulating unit and each piezoelectric power generation unit can be pre-stored in the controller. Furthermore, according to the positional relationship between the pressure regulating unit and each piezoelectric power generation unit near it in each sub-power generation system, the influence of the attitude change of the piezoelectric regulating unit on the ambient pressure received by the piezoelectric power generation unit is determined under the current environmental data, so as to maximize the power generation efficiency of the vehicle body power generation system when the on-vehicle battery permits.

[0099] In the embodiments of the present application, the controller can also adjust the vehicle running state in combination with other conditions to ensure the user experience.

[0100] Specifically, the controller can determine the adjustable range of the vehicle speed according to the currently obtained vehicle speed, and determine the adjustable range of the vehicle body attitude (or wheel deflection angle) based on the vehicle body attitude. Exemplarily, the adjustable range of the vehicle speed can be a percentage threshold not higher than the current vehicle speed and not higher than the maximum speed limit of the road where the vehicle is located. This percentage threshold can be, for example, 10%, 15% or 20% of the current vehicle speed, etc., so that the impact of vehicle speed adjustment on the vehicle occupants is small and the user driving experience is not affected. The adjustable range of the vehicle body attitude needs to ensure that there is no collision with surrounding vehicles. For example, the adjustable range of the vehicle body attitude can be a percentage threshold not higher than the current wheel deflection angle.

[0101] It can be seen that the maximum charging efficiency allowed by the on-vehicle battery is also affected by the vehicle running state data. In other words, the maximum charging efficiency allowed by the on-vehicle battery is determined based on the environmental data and the vehicle running state data.

[0102] S705: Control the electrical conduction between the piezoelectric power generation system and the on-vehicle battery.

[0103] In response to the battery state data satisfying the charging condition, the controller can control the electrical conduction between the piezoelectric power generation system and the on-vehicle battery to charge the battery through the piezoelectric power generation system. In some embodiments, the controller can also control the electrical conduction between the piezoelectric power generation system and the on-vehicle battery only after the adjustment of the vehicle running state and / or the attitude of the pressure regulating unit is completed, that is, when the adjusted vehicle running state and / or the adjusted attitude of the pressure regulating unit meet the maximum charging efficiency allowed by the on-vehicle battery.

[0104] In other words, this step S705 can be executed after the above step S702 or can be executed simultaneously with the above step S702.

[0105] S706: Obtain the updated environmental data and the updated vehicle running state data.

[0106] The controller monitors the environmental data around the vehicle and the vehicle body status data in real time. After the controller completes an adjustment of the vehicle and / or the pressure regulating unit based on the currently acquired environmental data and the vehicle operation status data, the environmental data acquired again (after the current moment) can be used as the updated environmental data; correspondingly, the vehicle operation status data acquired again (after the current moment) can be used as the updated vehicle operation status data.

[0107] S707. Adjust the vehicle operation status and / or the attitude of the pressure regulating unit according to the updated environmental data and the updated vehicle operation status data.

[0108] The controller can compare the updated environmental data with the previous environmental data to determine whether the environmental data has changed. When the environmental data has changed, adjust the vehicle operation status and / or the attitude of the pressure regulating unit based on the updated environmental data and the updated vehicle operation status data.

[0109] That is, before the vehicle-mounted battery is fully charged, the controller can detect the environmental data and the vehicle operation status data in real time to adjust the vehicle operation status and / or the attitude of the pressure regulating unit in real time according to the above data obtained in real time, so as to keep the power generation efficiency of the vehicle body power generation system maximized as much as possible.

[0110] S708. Respond to the updated battery status data meeting the charging completion condition and end the charging.

[0111] Before the vehicle-mounted battery is fully charged, the controller can also acquire the battery status data in real time and use the battery status data acquired again (after the current moment) as the updated battery status data. When the updated battery status data meets the charging completion condition, end the charging. In some embodiments, the charging completion condition can be, for example, any one of the vehicle-mounted battery reaching full charge and detecting a failure of the vehicle-mounted battery.

[0112] In response to the updated battery status data meeting the charging completion condition, the controller can control the vehicle body operation data to return to the original state, and / or control the attitude of the pressure regulating unit to return to the original attitude, and disconnect the electrical connection between the piezoelectric power generation system and the vehicle-mounted battery.

[0113] The vehicle control method using environmental pressure to generate electricity provided by the embodiments of the present application, by detecting the environmental data in the environment around the vehicle in real time, the controller dynamically adjusts the operation status of the vehicle, so that the piezoelectric power generation system can maximize the conversion of the environmental pressure acting on the vehicle body surface into electricity, thereby can utilize the energy in the surrounding environment to provide energy for the vehicle-mounted battery, and further can reduce the energy consumption loss of the vehicle itself and improve the vehicle energy economy.
