The invention discloses a vehicle-mounted mobile phone wireless charging heat dissipation noise improvement method and system and a vehicle, and the method comprises the steps: obtaining an in-vehicle environment temperature and first mobile phone charging power when a charging request of a mobile phone is detected; according to the in-vehicle environment temperature and the first mobile phone charging power, obtaining a judgment result of whether to start a cooling fan or not; if the judgment result is that the cooling fan is started, the current vehicle speed and the second mobile phone charging power are obtained, and the duty ratio of the cooling fan is set according to the current vehicle speed and the second mobile phone charging power. According to the method, the duty ratio of the cooling fan is determined by combining the environment temperature, the vehicle speed and the current wireless charging power of the mobile phone, the more reasonable duty ratio can be calculated, and the problems that the noise of the wireless charging cooling fan is large and the user experience is affected when the vehicle is static or runs in a low-speed pure electric mode are effectively solved.

    本申请公开了一种车载手机无线充电散热噪声的改善方法、系统及车辆,所述方法包括:当检测到手机的充电请求时,获取车内环境温度和第一手机充电功率;根据所述车内环境温度和所述第一手机充电功率得到是否开启散热风扇的判断结果;若所述判断结果为开启散热风扇,则获取当前车速和第二手机充电功率,根据所述当前车速和所述第二手机充电功率设置散热风扇的占空比。本申请结合了环境温度、车速以及手机当前的无线充电功率确定散热风扇占空比,能够计算出更加合理的占空比,有效解决了车辆静止或低速纯电行驶中,无线充电散热风扇噪声较大,影响用户体验问题。
