The invention discloses a power-assisted steering control method, device and system and a vehicle. The power-assisted steering control method comprises the specific steps that a vehicle speed signal and a torque signal are obtained; low-frequency assisting power and high-frequency assisting power are determined according to the vehicle speed signal and the torque signal; and the basic total assisting power is determined through the low-frequency assisting power and the high-frequency assisting power, and a motor provides corresponding power according to the magnitude of the basic total assisting power. The basic total assisting power obtained through the method is higher in reliability, better in stability and capable of better adapting to the steering hand feeling of a driver.
