The invention relates to the technical field of vehicles, in particular to a vehicle speed estimation method and device, a vehicle and a storage medium, and the method comprises the steps that the state of each wheel at the current moment is acquired, and the states comprise the first state and the second state; if the states of all the wheels are the first state, acquiring the speed of the vehicle at the historical moment before all the wheels enter the second state, and estimating the speed of the vehicle at the current moment according to the speed of the vehicle at the historical moment; otherwise, estimating the speed of the vehicle at the current moment according to the wheel speed of the wheel in the second state. Therefore, the problems of low accuracy, large estimation error and the like of vehicle speed estimation in related technologies are solved.
本申请涉及车辆技术领域,特别涉及一种车速估计方法、装置、车辆及存储介质,其中,方法包括:获取当前时刻每个车轮的状态,其中,状态包括第一状态和第二状态;若所有车轮的状态为第一状态,则获取所有车轮进入第二状态之前历史时刻车辆的车速,根据历史时刻车辆的车速估算当前时刻车辆的车速;否则根据处于第二状态车轮的轮速估算当前时刻车辆的车速。由此,解决了相关技术中对于车速估计的准确性较低,估计误差较大等问题。
