The invention relates to the technical field of vehicles, in particular to an electric vehicle control method, device and equipment and a storage medium. According to the electric vehicle control method, when the current vehicle driving state meets the abrupt slope constant speed mode starting condition, the corresponding actual vehicle speed when the abrupt slope constant speed mode is started is obtained, and the actual vehicle speed is set as the target vehicle speed when the electric vehicle goes downhill; theoretical motor feedback torque is calculated according to the target vehicle speed and the actually obtained actual vehicle speed, and after amplitude limiting is conducted on the theoretical motor feedback torque, the motor feedback torque obtained after amplitude limiting is sent to a motor controller to control a motor to work. In this way, constant-speed control driving can be conducted on the vehicle speed in the abrupt slope downhill process according to the requirement of a driver, the driver can be prevented from stepping on a brake pedal for a long time, the driving experience of the driver is improved, and meanwhile the constant-speed vehicle speed can improve the energy recovery utilization rate.
本发明涉及车辆技术领域,尤其涉及一种电动汽车控制方法、装置、设备及存储介质。本发明提出的电动汽车控制方法,在当前车辆行驶状态满足陡坡恒速模式开启条件时,获得陡坡恒速模式开启时对应的实际车速,并将实际车速设定为电动汽车下坡时的目标车速,根据目标车速和实际获得实际车速计算理论电机回馈扭矩,并对理论电机回馈扭矩限幅后将限幅后的电机回馈扭矩发送给电机控制器控制电机工作。这样可根据驾驶员需求在陡坡下坡的过程中对车速进行恒速控制行驶,可免去驾驶员长期踩踏刹车踏板,以提高驾驶员的驾驶体验,同时恒速车速还能够提高能量回收的利用率。
