[0021] The following combination Figure 1-Figure 3 Embodiments of the present invention are described.
[0022] Figure 1 This is a flow chart of the vibration noise control method for the start-up phase of a new energy vehicle provided by the present invention. Figure 1 As shown, the method includes the following steps 101, 102 and 103.
[0023] Step 101: Acquire a vehicle speed signal and an accelerator pedal depth signal of a new energy vehicle.
[0024] Step 102: When the vehicle speed signal is less than or equal to a first vehicle speed threshold and the accelerator pedal depth signal is greater than or equal to the first accelerator pedal depth threshold, the total power of the air conditioner is limited so that the speed of the air conditioner compressor does not exceed a preset speed value, and the interior sound control device of the new energy vehicle is controlled to turn on the interior sound wave mode to cover the vibration noise during the starting phase of the new energy vehicle. When the vehicle speed signal is greater than a second vehicle speed threshold, the interior sound control device is controlled to exit the interior sound wave mode; wherein the second vehicle speed threshold is greater than the first vehicle speed threshold.
[0025] Step 103: When the vehicle speed signal is greater than a third vehicle speed threshold and the accelerator pedal depth signal is greater than or equal to a second accelerator pedal depth threshold, control the exterior sound control device of the new energy vehicle to turn on the exterior sound wave mode, so that the combined sound effect of the sound output of the exterior sound control device and the body noise of the new energy vehicle reaches a preset exterior sound wave effect; when the vehicle speed signal is greater than a fourth vehicle speed threshold, or the accelerator pedal depth signal is less than the first accelerator pedal depth threshold, control the exterior sound control device to exit the exterior sound wave mode; wherein, the second accelerator pedal depth threshold is greater than the first accelerator pedal depth threshold, and the fourth vehicle speed threshold is greater than the third vehicle speed threshold.
[0026] Specifically, in an embodiment of the present invention, an integrated wire control brake system (WCBS) in a new energy vehicle is used to obtain a vehicle speed signal and an accelerator pedal depth signal of the new energy vehicle in real time during the starting phase of the new energy vehicle, thereby performing real-time monitoring of the vehicle speed and accelerator pedal depth.
[0027] In the embodiment of the present invention, the first vehicle speed threshold can be calibrated according to different vehicle models, and is not specifically limited. For example, the first vehicle speed threshold can be 22 km / h.
[0028] In the embodiment of the present invention, the first accelerator pedal depth threshold can be calibrated according to different modes of vehicle models, and is not specifically limited. For example, the first accelerator pedal depth threshold can be 10%.
[0029] In the embodiment of the present invention, the preset speed value can be calibrated according to different modes of vehicle models, and is not specifically limited. For example, the preset speed value can be set to 3500 rpm.
[0030] As an optional embodiment, when the vehicle speed signal is less than or equal to 22 km / h and the accelerator pedal depth signal is greater than or equal to 10%, the vehicle control unit (VCU) in the new energy vehicle implements total air conditioning power limitation, limiting the air conditioning compressor speed to no more than 3500 rpm. Simultaneously, the multimedia interface (MMI) system in the new energy vehicle controls the vehicle's in-vehicle sound control devices (such as the audio system) based on the vehicle's driving mode, enabling an in-vehicle sound wave mode to cover the vibration and noise during the new energy vehicle's starting phase. Because the acceleration performance of pure electric vehicles is comparable to that of supercars, the solution of this invention can provide electric vehicle owners with the roaring acceleration sound previously only available in traditional supercars.
[0031] The vehicle driving modes are divided into sports mode, economic mode, standard mode and invincible mode. According to different driving modes, choosing to match different sound wave modes can greatly enhance the customer's driving experience.
[0032] In the embodiment of the present invention, the second vehicle speed threshold can be calibrated according to different vehicle models, and is not specifically limited. For example, the second vehicle speed threshold can be 60 km / h.
[0033] As an optional embodiment, when the vehicle speed signal exceeds 60 km / h, the in-car sound wave mode begins to slowly exit. By controlling the in-car sound control device, the sound output is gradually reduced until the in-car sound wave mode is completely exited. This can be achieved by gradually reducing the volume and changing the sound effects to achieve a smooth transition, avoiding abrupt sound changes that affect the driving experience.
[0034] In the embodiment of the present invention, the third vehicle speed threshold can be calibrated according to different vehicle models, and is not specifically limited. For example, the third vehicle speed threshold can be 20 km / h.
[0035] In the embodiment of the present invention, the second accelerator pedal depth threshold can be calibrated according to different vehicle models, and is not specifically limited to this. For example, the second accelerator pedal depth threshold can be 20%.
[0036] As an optional embodiment, when the vehicle speed signal is greater than 20 km / h and the accelerator pedal depth signal is greater than or equal to 20%, the sound warning system (VSP) in the new energy vehicle controls the new energy vehicle's external sound control device (such as external audio or external speakers) according to the vehicle driving mode to turn on the external sound wave mode.
[0037] In the embodiment of the present invention, the fourth vehicle speed threshold can be calibrated according to different vehicle models, and is not specifically limited. For example, the fourth vehicle speed threshold can be 80 km / h.
[0038] As an optional embodiment, when the vehicle speed signal exceeds 80 km / h or the accelerator pedal depth signal is less than 10%, the system begins to slowly exit the external sound wave mode. By controlling the external sound control device, the sound output is gradually reduced until the external sound wave mode is completely exited. This can be achieved by gradually reducing the volume and changing the sound effects to achieve a smooth transition, ensuring more delicate and reasonable sound control, and avoiding abrupt sound changes that affect the external environment and the perception of surrounding people.
[0039] The present invention provides a method for controlling vibration and noise during the startup phase of a new energy vehicle. By acquiring a vehicle speed signal and an accelerator pedal depth signal from the new energy vehicle, when the vehicle speed signal is less than or equal to a first vehicle speed threshold and the accelerator pedal depth signal is greater than or equal to the first accelerator pedal depth threshold, the method limits the total power of the air conditioner so that the air conditioner compressor speed does not exceed a preset speed value. Furthermore, the method controls the vehicle's interior sound control device to activate an interior sound wave mode to cover the vibration and noise during the startup phase of the new energy vehicle. Furthermore, when the vehicle speed signal is greater than a third vehicle speed threshold and the accelerator pedal depth signal is greater than or equal to a second accelerator pedal depth threshold, the method controls the vehicle's exterior sound control device to activate an exterior sound wave mode, so that the combined sound output of the exterior sound control device and the vehicle's body noise achieves a preset exterior sound wave effect. This method not only solves the vibration and noise control problem during the startup phase of new energy vehicles, but also provides customers with an excellent supercar acceleration roar, enhancing the user experience.
[0040] In some embodiments, controlling an in-vehicle sound control device of a new energy vehicle to enable an in-vehicle sound wave mode includes: When the in-car sound wave mode is turned on, the body noise of the new energy vehicle is obtained; Adjust the sound output of the interior sound control device until the sound output of the interior sound control device covers the vehicle body noise.
[0041] In an embodiment of the present invention, the vehicle body noise includes vibration noise generated by the motor and heat pump air-conditioning compressor when the new energy vehicle accelerates and starts, and also includes other types of noise generated by the new energy vehicle during the startup phase.
[0042] To provide the driver with a better driving experience, the in-car sound wave mode is activated, allowing the in-car sound effects to override vibration noise and achieve a sound wave effect. The specific sound characteristics of the in-car sound wave effect can be determined by the driving mode set by the user in the in-car multimedia system, and each driving mode can correspond to a different in-car sound wave effect.
[0043] After the car sound wave mode is turned on, in order to ensure that the sound output can cover the body noise, turn on the car sound wave mode and adjust the sound output of the car sound control device according to the level of the body noise until the sound output can completely cover the body noise, ensuring that the driver and passengers mainly hear the preset music or sound effects.
[0044] In some embodiments, controlling an external sound control device of a new energy vehicle to enable an external sound wave mode includes: When the external sound wave mode is turned on, the body noise of the new energy vehicle is obtained; According to the vehicle body noise, the sound output of the exterior sound control device is adjusted until the combined sound effect of the sound output of the exterior sound control device and the vehicle body noise reaches a preset exterior sound effect.
[0045] Specifically, when the exterior sound wave mode is turned on, the sound output of the exterior sound control device is adjusted according to the characteristics of the vehicle body noise until the combined sound effect of the sound output and the vehicle body noise achieves the preset exterior sound wave effect, such as enhancing dynamics and improving recognition.
[0046] The technical solutions of the present invention are illustrated below through specific examples.
[0047] The main design idea is: when VSP and MMI receive the vehicle speed signal and accelerator pedal depth signal sent by WCBS, and the strategic conditions are met, MMI and VSP control the speakers inside and outside the car to turn on the sound waves when the vehicle starts, providing two completely different modes of sound waves inside and outside the car. The sound waves inside the car provide a variety of sound wave modes for customers to choose from on the MMI interface. The driving modes are divided into sports mode, economic mode, standard mode and invincible mode. According to different driving modes, different sound wave modes can be selected to greatly enhance the customer's driving experience; the sound waves outside the car can change according to the vehicle speed.
[0048] The implementation strategy is as follows: When the vehicle speed is ≤22 km / h and VCU_Acc_pedal_position ≥10%, the VCU limits the total air conditioning power to 3500 rpm, keeping the compressor speed below 3500 rpm. The MMI then activates the sound wave mode, controlling the speakers based on the vehicle's driving mode. Sound wave mode slowly exits when the vehicle speed exceeds 60 km / h. (The specific values in this example can be calibrated based on different vehicle modes, with VCU_Acc_pedal_position representing the accelerator pedal input depth.)
[0049] When the vehicle speed exceeds 20 km / h and the VCU_Acc_pedal_position exceeds 20%, the VSP activates the external acceleration sound wave mode and slowly exits the sound wave mode when the vehicle speed exceeds 80 km / h or the VCU_Acc_pedal_position decreases to less than 10%. (The accelerator pedal input depth and the vehicle speed at which the mode is exited can be calibrated based on the vehicle model. Furthermore, when the vehicle speed is less than 20 km / h, the VSP is required by law to issue an appropriate warning sound to personnel outside the vehicle.)

The vibration and noise control device for a new energy vehicle during its startup phase described below and the vibration and noise control method for a new energy vehicle during its startup phase described above can be used in correspondence with each other.
