The invention relates to the technical field of hybrid vehicles, in particular to an engine noise control method and device for a hybrid vehicle, and the method comprises the steps: obtaining a current navigation route of the vehicle, confirming at least one expected driving mode of the vehicle and a target expected value of the charge quantity of a battery under the condition that the vehicle is detected to enter a hybrid noise reduction mode, and controlling the engine to charge the vehicle based on the engine noise reduction working interval corresponding to the at least one expected driving mode and the target expected value, so that the engine meets a preset noise reduction condition until the vehicle exits the hybrid power noise reduction mode. According to the embodiment of the invention, the electric quantity required by the battery to complete the journey can be determined by combining different driving modes corresponding to the target driving route with map navigation, so that the power battery is charged to the target expected value in advance at a relatively low engine rotating speed, and the probability that the engine enters a high rotating speed is reduced; therefore, the radiation noise of the engine in the running process of the vehicle is reduced, and the comfort of the vehicle is improved.
本申请涉及混动车辆技术领域,特别涉及一种混动车辆的发动机噪声控制方法及装置,其中,方法包括:在检测到车辆进入混动降噪模式的情况下,获取车辆的当前导航路线,确认车辆的至少一个预期驾驶模式和电池电荷量的目标期望值,基于至少一个预期驾驶模式对应的发动机降噪工作区间和目标期望值控制发动机对车辆进行充电,以使发动机满足预设降噪条件,直至车辆退出混动降噪模式。本申请实施例可以通过目标行驶路线对应的不同驾驶模式结合地图导航确认电池完成路程所需要电量,从而提前在较低发动机转速下将动力电池充电至目标期望值,降低发动机进入高转速的几率,进而减轻了车辆行驶过程中的发动机辐射噪声,提高了车辆的舒适性。
