The invention discloses a vehicle warning tone control method and device and a vehicle. The vehicle comprises a front bumper cross beam, a sound production part arranged on the front bumper cross beam and a front bumper protection plate arranged on the periphery of the front bumper cross beam. The front bumper protection plate is provided with a through hole adjacent to the sound production part and an adjusting valve structure for adjusting the opening area of the through hole. The vehicle warning tone control method comprises the following steps that the current vehicle speed of a vehicle is obtained; and according to the current vehicle speed, the target opening area of the through hole is determined, and the adjusting valve structure is controlled to adjust the opening area of the through hole to the target opening area. The through holes are formed in the front bumper protection plate arranged on the periphery of the front bumper cross beam, so that the sound insulation index of the front bumper protection plate is changed to a certain degree, a body sound source can further reduce and slightly influence noise in a vehicle, and the problem that when an existing vehicle improves warning tones outside the vehicle, the noise in the vehicle is too loud, and the noise is too high is solved. And the feeling of people in the electric automobile is influenced.

    本发明公开一种车辆提示音的控制方法、控制装置和车辆,车辆包括前保险杠横梁、设于前保险杠横梁的发声部、以及设于前保险杠横梁外围的前保险杠护板,前保险杠护板上开设有邻近发声部设置的通孔、以及调节通孔的开度面积的调节阀结构;车辆提示音的控制方法包括以下步骤:获取车辆的当下车速;根据当下车速,确定通孔的目标开度面积,并控制调节阀结构调节通孔的开度面积至目标开度面积。通过在设于前保险杠横梁的外围的前保险杠护板上开设通孔,使得在一定程度上改变前保险杠护板的隔声量,本体声源可以进一步降低,更小地影响车内噪声,以解决现有车辆在提高车外提示音时,却导致车内声音过大,影响电动汽车内人员感受的问题。
