The invention relates to the technical field of vehicles, and particularly discloses a vehicle starting speed calculation method and device, a vehicle and a storage medium. According to the vehicle starting speed calculation method, it is determined that the vehicle is in a static state and vehicle starting is recognized to serve as the reference of vehicle starting speed calculation, and the starting time point is conveniently and accurately determined; by determining the starting mode of the vehicle, the starting state of the vehicle can be determined, and corresponding starting speed calculation methods can be adopted subsequently according to different starting modes; and finally, in the conventional starting mode, the starting speed of the vehicle can be accurately calculated based on the rotating speed of the motor because the motor of the vehicle is judged not to slip. In the slip starting mode, as the motor of the vehicle is judged to slip, the longitudinal acceleration of the whole vehicle is increased outside the rotating speed of the motor for correction, and the starting speed of the vehicle can be accurately calculated, so that deviation is avoided, and the starting speeds in different starting states can be rapidly and accurately calculated.

    本发明涉及车辆技术领域,具体公开了一种车辆起步车速计算方法、装置、车辆和存储介质,根据本发明的车辆起步车速计算方法,先通过确定车辆处于静止状态且识别到车辆起步,作为车辆起步车速计算的基准,便于准确的确定起步时间点;再通过确定车辆的起步模式,有助于明确车辆的起步状态,便于后续根据不同的起步模式采取对应的起步车速计算方法;最后在常规起步模式下,由于判定车辆电机未发生打滑,此时基于电机转速,即可准确的计算车辆的起步车速;在打滑起步模式下,由于判定车辆电机发生了打滑,此时在电机转速外增加整车纵向加速度进行修正,即可准确的计算车辆的起步车速,从而避免了偏差,可以快速准确的计算不同起步状态下的起步车速。
