The invention discloses a vehicle performance optimization method and device and a computer readable storage medium. The method comprises the steps that a whole vehicle working mode and a whole vehicle driving mode of the hybrid power vehicle are obtained; under the condition that the whole vehicle working mode is the series connection mode and the whole vehicle driving mode is the preset mode, the vehicle speed of the hybrid vehicle, the opening degree of an accelerator pedal, the allowable power of a battery and the required power of the whole vehicle are obtained; acquiring a plurality of initial power change slopes corresponding to an engine of the hybrid vehicle; determining a target power change slope of an engine of the hybrid vehicle based on the vehicle speed, the accelerator pedal opening, the allowable power, the required power and the plurality of initial power change slopes; and controlling the power change of the engine based on the target power change slope. According to the invention, the technical problems of high engine noise and poor vehicle drivability and comfort of the hybrid vehicle in a series working mode are solved.

    本发明公开了一种车辆性能优化方法、装置及计算机可读存储介质。其中,该方法包括:获取混合动力车辆的整车工作模式和整车驾驶模式;在整车工作模式为串联模式,且整车驾驶模式为预设模式的情况下,获取混合动力车辆的车速,油门踏板开度,电池的许用功率和整车的需求功率;获取与混合动力车辆的发动机对应的多个初始功率变化斜率;基于车速,油门踏板开度,许用功率,需求功率和多个初始功率变化斜率,确定混合动力车辆的发动机的目标功率变化斜率;基于目标功率变化斜率,控制发动机的功率变化。本发明解决了混合动力车辆在串联工作模式下发动机噪声大、车辆驾驶性和舒适性差的技术问题。
