The invention discloses a driving control method and device of an electric automobile and the electric automobile. The method comprises the steps: detecting whether the electric automobile enters a single-pedal control driving mode or not; when it is detected that the vehicle is in the single-pedal control driving mode, obtaining the current acceleration opening degree and the current braking opening degree of an accelerator pedal and a braking pedal; if the current braking opening degree is smaller than or equal to the first preset threshold value and the current acceleration opening degree is greater than the second preset threshold value, after the driving motor is controlled to output the corresponding acceleration torque according to the current acceleration opening degree, when the current acceleration opening degree returns to zero, controlling the driving motor to output the braking torque, and performing energy recycling while the electric automobile is braked. Therefore, the parking problem of the electric automobile in the single-pedal driving mode in the related technology is solved, the use frequency of the brake pedal is reduced through the parking function controlled by the motor in the single-pedal control driving mode, and the driving convenience and the energy utilization efficiency of the electric automobile are improved.

    本申请公开了一种电动汽车的驾驶控制方法、装置及电动汽车,其中,方法包括:检测电动汽车是否进入单踏板控制驾驶模式;在检测到处于单踏板控制驾驶模式时,获取加速踏板和制动踏板的当前加速开度和当前制动开度;若当前制动开度小于等于第一预设阈值,且当前加速开度大于第二预设阈值,则在根据当前加速开度控制驱动电机输出对应加速扭矩后,当前加速开度回到零时,控制驱动电机输出制动扭矩,对电动汽车进行制动的同时进行能量回收。由此,解决了相关技术中电动汽车单踏板驾驶模式下的停车问题,在单踏板控制驾驶模式,依靠电机控制的停车功能,降低了制动踏板的使用频率,提高了电动汽车驾驶便捷性以及能量利用效率。
