The invention discloses a noise control method, device and terminal for an engine of a tandem hybrid vehicle type, and belongs to the technical field of automobiles. The noise control method comprises the steps that vehicle power curve data and engine operation curve data of different accelerations are obtained respectively; determining battery total power data according to the vehicle power curve data of different accelerations and the engine operation curve data; and according to the battery total power data, reasonably distributing engine power and battery power in an electric control calibration mode to control engine noise under an acceleration working condition. According to the method, the power of the engine under different vehicles is ingeniously applied by applying the technical characteristics of the current hybrid power vehicle model, the wind noise and the road noise in the driving process are used for shielding the engine noise, a basis is provided for battery model selection, the battery discharge power and SOC requirements are provided, the noise level optimization of the engine can be reduced, and therefore the hardware control cost of the engine is reduced.
本发明公开了一种串联式混动车型发动机噪声控制方法、装置及终端,属于汽车技术领域,包括:分别获取不同加速度整车功率曲线数据和发动机运行曲线数据;根据所述不同加速度整车功率曲线数据和发动机运行曲线数据确定电池总功率数据;根据所述电池总功率数据通过电控标定方式对发动机功率与电池功率合理分配对加速工况下的发动机噪声控制。本发明应用当前混动车型技术特点巧妙应用发动机在不同车辆下的功率,利用行驶过程中风噪声与路噪声掩敝发动机噪声,为电池选型提供依据,提出电池放电功率与SOC需求,可减少发动机本身噪声水平优化从而降低发动机硬件控制成本。
