The invention provides a gear shifting control method and device, a vehicle, a storage medium and a program product, the method is applied to the vehicle, and the method comprises the steps that the engine rotating speed and the input shaft rotating speed of a transmission in the gear shifting synchronization stage are obtained; based on the engine rotating speed and the input shaft rotating speed, target torque for maintaining synchronization of the engine rotating speed and the input shaft rotating speed in the gear shifting synchronization stage is determined; and the engine is controlled to output the target torque until the transmission completes the gear shifting action. According to the method, the engine can be controlled to increase the torque in the gear shifting synchronization stage, so that the rotating speed of the engine is transiently parallel to the rotating speed of the input shaft of the transmission or the rotating speed gradient of the two rotating speeds at the moment of shaft penetrating is reduced, vehicle rushing and noise in the gear shifting process are reduced, and the driving feeling is improved.

    本申请提供了换挡控制方法、装置、车辆、存储介质及程序产品,该方法应用于车辆,该方法包括:获取换挡同步阶段的发动机转速和变速器的输入轴转速;基于发动机转速和输入轴转速,确定换挡同步阶段维持发动机转速和输入轴转速同步的目标扭矩;控制发动机输出目标扭矩,直到变速器完成换挡动作。该方法能够在换挡同步阶段控制发动机增加扭矩,以使发动机转速与变速器胡输入轴转速短暂平行或减小穿轴瞬间两个转速的转速梯度,以减少换挡过程中车辆的闯动和噪声,提高驾乘感受。
