The invention discloses a vehicle demand torque prediction method, a computer program product and a storage medium. The method comprises the steps that in a preset time period after a whole vehicle is powered on, an operation data set of a target vehicle is collected, and the operation data set at least comprises the vehicle speed, the engine rotating speed and the accelerator pedal opening degree; when the vehicle speed is smaller than or equal to a preset vehicle speed threshold value and the duration of the vehicle speed is smaller than a preset duration, or when the vehicle speed is larger than the preset vehicle speed threshold value, multi-type operation states of the target vehicle are judged according to the operation data set; and predicting the required torque of the target vehicle according to the multi-type operation state and the first torque function. The technical problem that the adaptability to different driving scenes is poor due to the fact that the vehicle demand torque is predicted according to a fixed demand torque and accelerator pedal relation curve and the current accelerator pedal opening degree of the vehicle in the prior art is solved.
本发明公开了一种车辆需求扭矩预测方法、计算机程序产品、存储介质。其中,该方法包括:在整车上电后的预设时间周期内,采集目标车辆的运行数据集,其中,运行数据集至少包括车速、发动机转速、油门踏板开度;响应于车速小于等于预设车速阈值并且车速的持续时间小于预设时长,或者响应于车速大于预设车速阈值,根据运行数据集判断目标车辆的多类型运行状态;根据多类型运行状态和第一扭矩函数预测目标车辆的需求扭矩。本发明解决了现有技术根据固定的需求扭矩与油门踏板关系曲线以及车辆当前油门踏板开度预测车辆需求扭矩导致对不同驾驶场景的适应性差的技术问题。
