Description

Technical Field

[0002] With the development of vehicle technology and the substantial increase in the number of vehicles, people have higher and higher requirements for vehicle comfort, among which vehicle sound insulation performance is one of the important criteria for measuring vehicle comfort. At present, the internal and external circulation pressure relief ports of the vehicle passenger compartment usually adopt exhaust curtain pressure relief ports to ensure that the pressure in the cabin can be balanced and the air in the cabin can flow out normally. However, this method has the following disadvantages: First, when the vehicle is a rear-wheel drive or four-wheel drive model, the powertrain axle is arranged under the sheet metal of the trunk floor, which is very close to the pressure relief port, and the pressure relief port is directly connected to the interior of the vehicle, and the power noise will be directly transmitted into the vehicle through the exhaust curtain; second, when the vehicle is driving at high speed, external noise, tire noise and other noises will be transmitted into the vehicle from the pressure relief port. The noise transmitted into the cockpit will reduce the comfort of the passengers in the passenger compartment.

[0040] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The accompanying drawings are used to provide a further understanding of the present disclosure and constitute a part of the specification. Together with the following specific embodiments, they are used to explain the present disclosure but do not constitute a limitation of the present disclosure. In the accompanying drawings:

[0042] Figure 1 is a flow chart of a vehicle noise reduction method provided by an exemplary embodiment of the present disclosure;

[0044] Figure 3 is a block diagram of a vehicle noise reduction device provided by another exemplary embodiment of the present disclosure. DETAILED DESCRIPTION

[0045] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0046] Figure 1 FIG. 1 is a flow chart of a vehicle noise reduction method provided by an exemplary embodiment of the present disclosure. The method can be applied to an ECU (Electronic Control Unit) on a vehicle. Figure 1 As shown, the method may include S101 to S103.

[0047] S101, obtaining current vehicle status information in real time, wherein the current vehicle status information includes current vehicle speed, current cabin pressure information, and current air conditioning circulation mode information.

[0048] Exemplarily, the current vehicle speed may be acquired via a vehicle speed sensor.

[0049] The higher the vehicle speed, the greater the tire noise and wind noise generated during driving. When the noise is loud, in order to prevent the noise from entering the car and reducing the comfort of the passengers in the cabin, the vehicle noise reduction function needs to be turned on.

[0050] Exemplarily, the current cabin pressure information may be acquired via a cabin pressure sensor placed on the ceiling.

[0051] When the cabin pressure is too high, it will cause people in the cabin to experience uncomfortable feelings such as chest tightness and difficulty breathing. By obtaining the current cabin pressure information, it is possible to determine whether the current cabin environment for the passengers is comfortable, and avoid turning on the vehicle noise reduction function when the cabin pressure is high, causing the cabin pressure to continue to rise, further aggravating the discomfort of people in the cabin.

[0052] Exemplarily, the passenger compartment has an internal circulation pressure relief port and an external circulation pressure relief port. The internal circulation pressure relief port is at the front of the passenger compartment, and the external circulation pressure relief port is at the rear of the passenger compartment. The current air-conditioning circulation mode information can be obtained by a wind speed sensor placed at the external circulation pressure relief port of the vehicle. When the wind speed at the external circulation pressure relief port of the vehicle is greater than a preset wind speed threshold (such as the wind speed threshold is 3m / s), it can be considered that the vehicle air-conditioning is in external circulation mode.

[0053] The air conditioning circulation mode is divided into internal and external circulation modes. The internal circulation mode closes the ventilation ducts inside and outside the car. There is no air circulation if the fan is not turned on. When the fan is turned on, the airflow inhaled only comes from inside the car, forming an air circulation inside the vehicle. At this time, the vehicle is in a closed state and noise is difficult to enter the car. Therefore, when the air conditioner is in the internal circulation state, there is no need to turn on the vehicle noise reduction function. The external circulation mode uses the fan to draw the air outside the car into the car, that is to say, the ventilation ducts outside and inside the car are open, and noise can enter the car, so the vehicle noise reduction function needs to be turned on.

[0054] S102: When no vehicle noise reduction function activation instruction issued by the user is received, determining whether to activate the vehicle noise reduction function according to current vehicle status information.

[0055] S103, when it is determined that the vehicle noise reduction function is turned on, the sound insulation cotton driving mechanism is controlled to drive the sound insulation cotton to cover the vehicle's external circulation pressure relief port to reduce the noise inside the vehicle.

[0056] For example, when no instruction to turn on the vehicle noise reduction function is received from the user, that is, when there is no human intervention, based on the current vehicle status information, if it is determined that the vehicle noise reduction function is turned on, the ECU will output an electrical signal indicating that the vehicle noise reduction function is in the on state to the drive motor controller, so that the drive motor drives the mechanical structure to block the sound insulation cotton at the vehicle's external circulation pressure relief port to reduce the noise inside the vehicle.

[0057] Through the above technical solution, the current vehicle status information is obtained in real time. In the case of not receiving the vehicle noise reduction function activation instruction issued by the user, it is determined whether to activate the vehicle noise reduction function according to the current vehicle status information. It is possible to automatically determine whether the vehicle noise reduction function needs to be activated according to the current vehicle status information without human intervention, thereby improving the intelligence of the vehicle and the user's riding experience. In addition, when it is determined that the vehicle noise reduction function is activated, the sound insulation cotton driving mechanism is controlled to drive the sound insulation cotton to block the vehicle's external circulation pressure relief port. The sound insulation cotton can prevent noise from entering the passenger compartment from the external circulation pressure relief port, thereby achieving the effect of reducing the noise inside the vehicle. The reduction of the noise inside the vehicle can improve the comfort of the passengers in the passenger compartment, avoid driving safety problems caused by excessive noise inside the vehicle distracting the driver's attention, and improve the safety of the vehicle.

[0058] Optionally, determining whether to enable the vehicle noise reduction function according to the current vehicle status information in S102 may include:

[0059] If the current vehicle speed is greater than a preset vehicle speed threshold, the current cabin pressure information is less than a preset pressure threshold, and the current air-conditioning circulation mode information indicates that the vehicle air-conditioning is in an external circulation mode, it is determined to turn on the vehicle noise reduction function.

[0060] Exemplarily, the vehicle speed threshold can be pre-set, for example, set to 100km / h. If the current vehicle speed obtained by the vehicle speed sensor is greater than 100km / h, it indicates that the vehicle is in a high-speed driving state, and the tire noise and wind noise generated during the vehicle driving are relatively large. The pressure threshold can be pre-set, for example, set to 40Pa. If the cabin pressure obtained by the cabin pressure sensor is less than 40Pa, it indicates that the cabin pressure is within the normal range. Even if the sound insulation cotton blocks the vehicle's external circulation pressure relief port and reduces the entry of outside air, it will not make the passengers in the cabin feel uncomfortable. The air conditioning circulation mode information indicates that the vehicle's air conditioning is in external circulation mode, which can indicate that outside air or noise can enter the vehicle. If the above conditions are met, it is determined that the vehicle noise reduction function needs to be turned on at this time.

[0061] Through the above technical solution, according to the current vehicle speed, the current cabin pressure information, and the current air-conditioning circulation mode information, it can automatically determine whether the vehicle noise reduction function needs to be turned on, thereby improving the intelligence level of the vehicle and enhancing the user's riding experience.

[0062] Optionally, the vehicle noise reduction method provided by the present disclosure may further include:

[0063] When a vehicle noise reduction function activation instruction sent by a user is received, it is determined to activate the vehicle noise reduction function.

[0064] Among them, if a vehicle noise reduction function activation instruction issued by a user is received, the vehicle noise reduction function is activated according to the user's wishes, and whether the vehicle noise reduction function needs to be activated is no longer determined based on the current vehicle status information.

[0065] Exemplarily, the user can issue a vehicle noise reduction function activation instruction through the terminal, such as issuing the instruction through a mobile phone APP. When the terminal receives the activation instruction input by the user, it can send the activation instruction to the vehicle communication module, and the vehicle communication module can forward the activation instruction to the ECU. Exemplarily, the user can also issue a vehicle noise reduction function activation instruction through the vehicle display screen. The vehicle noise reduction function switch button can be displayed on the vehicle display screen, and the user can set whether the vehicle noise reduction function switch is turned on. If the user sets the switch to the on state, the ECU can receive the vehicle noise reduction function activation instruction. Regardless of whether the vehicle is in driving or parking state, the ECU will output the on-state electrical signal to the drive motor controller, and let the drive motor drive the mechanical structure to block the sound insulation cotton at the vehicle's external circulation pressure relief port. Alternatively, a physical switch for the vehicle noise reduction function can be installed on the vehicle, and the user can set whether the vehicle noise reduction function is turned on by operating the physical switch. Through the setting of the vehicle noise reduction function switch, the intention of the people in the cabin can be accurately obtained, making the vehicle more intelligent and improving the user experience.

[0066] Optionally, after controlling the sound insulation cotton driving mechanism to drive the sound insulation cotton to cover the vehicle external circulation pressure relief port, the vehicle noise reduction method provided by the present disclosure may further include:

[0067] Determine whether the vehicle noise reduction function shut-off conditions are met;

[0068] If it is determined that the conditions for shutting down the vehicle noise reduction function are met, the sound insulation cotton driving mechanism is controlled to drive the sound insulation cotton so as not to block the vehicle's external circulation pressure relief port.

[0069] For example, when it is determined that the conditions for shutting down the vehicle noise reduction function are met, the ECU outputs an electrical signal of the shut-down state to the drive motor controller, so that the drive motor drives the mechanical structure to remove the sound insulation cotton blocking the vehicle's external circulation pressure relief port, so that air can enter the cabin through the external circulation pressure relief port, avoiding the continuous increase of cabin pressure, thereby reducing the cabin pressure.

[0070] Optionally, the above vehicle noise reduction function shut-down condition may include at least one of the following:

[0071] A vehicle noise reduction function shut-down instruction sent by a user is received, and the current cabin pressure information is greater than or equal to a preset pressure threshold.

[0072] Among them, users can issue vehicle noise reduction function shutdown instructions through mobile phone APP, the vehicle noise reduction function switch button displayed on the vehicle display screen, or the physical switch of the vehicle noise reduction function on the vehicle. If the vehicle noise reduction function shutdown instruction issued by the user is received, the vehicle noise reduction function can be fully respected and turned off.

[0073] Sound insulation cotton is a fiber porous sound insulation material with air permeability. There are a large number of tiny interconnected pores inside the material. Sound waves can penetrate into the material along these pores and rub against the material to convert sound energy into heat energy. When the air conditioner is in external circulation mode, if the vehicle is driving, the air flow will be automatically sucked into the vehicle using wind pressure. If the vehicle is stationary, the air outside the vehicle can also enter the blower along the ventilation duct and blow into the vehicle. That is, if the sound insulation cotton is blocked at the vehicle's external circulation pressure relief port, while soundproofing, due to the air permeability of the sound insulation cotton, air can still enter the vehicle, which will cause the pressure in the passenger compartment to continue to increase. The cabin pressure sensor can send the current cabin pressure information obtained in real time to the ECU. If the current cabin pressure is greater than the preset cabin pressure threshold (such as the current cabin pressure is greater than 40pa), in order to avoid excessive cabin pressure causing discomfort to the cabin personnel, it is determined to turn off the vehicle noise reduction function.

[0074] Through the above technical solution, if a vehicle noise reduction function shutdown instruction is received from the user, the vehicle noise reduction function can be turned off, fully respecting the user's intention. Judging whether to turn off the vehicle noise reduction function based on the current cabin pressure information can avoid excessive cabin pressure causing discomfort to the cabin personnel, thereby improving the user's riding experience.

[0075] Optionally, the vehicle noise reduction method provided by the present disclosure may further include:

[0076] Output the current vehicle noise reduction function status prompt information, which is used to prompt the user whether the vehicle noise reduction function is turned on.

[0077] For example, the ECU may output the vehicle noise reduction function status prompt information to a vehicle prompt device, which may include, for example, a vehicle display screen and a speaker.

[0078] For example, when the vehicle noise reduction function is turned on, a prompt message "the vehicle noise reduction function is turned on" is displayed on the vehicle display screen, and when the vehicle noise reduction function is turned off, a prompt message "the vehicle noise reduction function is turned off" is displayed on the vehicle display screen. Alternatively, a speaker can be provided in the vehicle, and the above information can be broadcasted by the speaker to prompt the user, so that the user knows the on state of the vehicle noise reduction function.

[0079] Based on the same inventive concept, the present disclosure also provides a vehicle noise reduction device. Figure 2is a block diagram of a vehicle noise reduction device 200 provided by an exemplary embodiment of the present disclosure. Figure 2 , the vehicle noise reduction device 200 may include:

[0080] The acquisition module 201 is used to acquire the current vehicle status information in real time, and the current vehicle status information includes the current vehicle speed, the current cabin pressure information, and the current air conditioning circulation mode information;

[0081] The first determination module 202 is used to determine whether to turn on the vehicle noise reduction function according to the current vehicle state information when no vehicle noise reduction function turn-on instruction issued by the user is received;

[0082] The first control module 203 is used to control the sound insulation cotton driving mechanism to drive the sound insulation cotton to cover the vehicle's external circulation pressure relief port to reduce the noise inside the vehicle when it is determined that the vehicle noise reduction function is turned on.

[0083] Through the above technical solution, the current vehicle status information is obtained in real time. In the case of not receiving the vehicle noise reduction function activation instruction issued by the user, it is determined whether to activate the vehicle noise reduction function according to the current vehicle status information. It is possible to automatically determine whether the vehicle noise reduction function needs to be activated according to the current vehicle status information without human intervention, thereby improving the intelligence of the vehicle and the user's riding experience. In addition, when it is determined that the vehicle noise reduction function is activated, the sound insulation cotton driving mechanism is controlled to drive the sound insulation cotton to block the vehicle's external circulation pressure relief port. The sound insulation cotton can prevent noise from entering the passenger compartment from the external circulation pressure relief port, thereby achieving the effect of reducing the noise inside the vehicle. The reduction of the noise inside the vehicle can improve the comfort of the passengers in the passenger compartment, avoid driving safety problems caused by excessive noise inside the vehicle distracting the driver's attention, and improve the safety of the vehicle.

[0085] If the current vehicle speed is greater than a preset vehicle speed threshold, the current cabin pressure information is less than a preset pressure threshold, and the current air-conditioning circulation mode information indicates that the vehicle air-conditioning is in an external circulation mode, it is determined to turn on the vehicle noise reduction function.
