The invention relates to the technical field of new energy automobiles, and provides a dual-motor pure electric vehicle, a noise reduction processing method and device thereof and a storage medium, and the method comprises the steps that when the vehicle is in a stop state, a gearbox of the vehicle is controlled to be in a neutral gear state; after the vehicle is started, when the current torque demand of the vehicle is within a rated external characteristic area of a first motor, the first motor is controlled to provide torque; when the current torque demand exceeds a rated external characteristic area of the first motor, whether a gear shifting condition is met or not is determined; when it is determined that the gear conversion condition is met, a gearbox of the vehicle is controlled to be converted into a first gear state from a neutral gear state; and when the rotating speed of the first motor of the vehicle exceeds the preset second-gear critical rotating speed, a gearbox of the vehicle is controlled to be converted into a second-gear state from the first-gear state. By means of the technical scheme, the duration time of the first-gear state is reduced as much as possible, and therefore tooth knocking noise in the low-speed state is reduced.

    本申请涉及新能源汽车技术领域,提出了一种双电机纯电车辆及其降噪处理方法、装置和存储介质,其中,方法包括:当车辆处于停止状态时,控制所述车辆的变速箱处于空挡状态;当所述车辆起步后,当所述车辆的当前扭矩需求在第一电机的额定外特性区域以内时,控制所述第一电机提供扭矩;当所述当前扭矩需求超过所述第一电机的额定外特性区域时,确定是否满足挡位转换条件;当确定满足挡位转换条件时,控制所述车辆的变速箱从空挡状态转换为一挡状态;当所述车辆的第一电机的转速超过预设二挡临界转速时,控制所述车辆的变速箱从一挡状态转换为二挡状态。通过该技术方案,尽量减少了一挡状态的持续时间,从而减少低速状态下的敲齿噪音。
