The invention relates to an electric power steering control method and device, a vehicle and a readable storage medium. The electric power steering control method comprises the steps that an intelligent driving control mode, a driver hand force value and a vehicle speed are obtained; according to the intelligent driving control mode, the hand force value of the driver and the vehicle speed, an intelligent driving torque coefficient, a first intelligent driving target torque and an assisting torque are obtained; calculating a target motor torque according to the intelligent driving torque coefficient, the first intelligent driving target torque and the assistance torque; and controlling the output torque of a steering motor according to the target motor torque. According to the driving control mode, the hand power value of the driver and the vehicle speed, the first target torque and the intelligent driving torque coefficient related to the intelligent auxiliary driving system can be adjusted, the power-assisted torque related to the control end of the driver can be adjusted, and then transfer of the control right under man-machine co-driving is achieved through the torque adjusting method; and a redundant mechanical structure is not needed, so that the control cost of man-machine co-driving is reduced.
