The invention discloses an electric automobile single pedal mode control method and device and a storage medium, and the method comprises the following steps: obtaining working condition parameters of an electric automobile in the deceleration braking process, and determining the total deceleration currently required by the automobile according to the working condition parameters; according to the working condition parameters, the power recovery deceleration which can be provided by the automobile at present is determined, and whether the power recovery deceleration reaches the total deceleration or not is judged; if it is judged that the power recovery deceleration reaches the total deceleration, a motor of the automobile is driven only through the recovery power to provide the power recovery deceleration so as to achieve the total deceleration; if it is judged that the power recovery deceleration cannot reach the total deceleration, the power recovery deceleration is provided through a motor for driving the automobile through the recovery power, meanwhile, supplementary deceleration is provided through hydraulic braking, and the total deceleration is achieved through the power recovery deceleration and the supplementary deceleration jointly. In this way, the deceleration of automobile braking is provided through automobile battery recharging and hydraulic braking, and normal starting of the single pedal function is guaranteed.

    本申请公开了电动汽车单踏板模式控制方法、装置及存储介质,包括以下步骤:获取电动汽车的减速制动过程中的工况参数,根据工况参数确定汽车当前需求的总减速度;根据工况参数确定汽车当前所能提供的动力回收减速度,判断动力回收减速度是否达到总减速度;若判断动力回收减速度达到总减速度,仅通过回收动力驱动所述汽车的电机提供动力回收减速度以实现总减速度;若判断动力回收减速度不能达到总减速度,在通过回收动力驱动汽车的电机提供动力回收减速度的同时还通过液压制动提供补充减速度,通过动力回收减速度和补充减速度共同实现总减速度。如此,通过汽车电池回充和液压制动提供汽车制动的减速度,保证了单踏板功能的正常开启。
