The invention provides a guide control method and device for independent rotating wheels of a railway vehicle. The guide control method comprises the steps that a motor rotating speed difference instruction value for driving a target wheel set is obtained according to a preset wheel transverse displacement instruction value and a wheel transverse displacement actual value of the target wheel set; a motor guiding torque instruction value is obtained according to the motor rotating speed difference instruction value and the motor rotating speed actual difference value; the target wheel set comprises a first wheel and a second wheel, and the actual motor rotating speed difference is the difference between the actual rotating speed of the first wheel corresponding to a first motor and the actual rotating speed of the second wheel corresponding to a second motor; according to the motor guiding torque instruction value, the initial motor torque instruction values of the first motor and the second motor are adjusted to obtain a first motor torque instruction value and a second motor torque instruction value; and respectively controlling the first motor and the second motor according to the first motor torque command value and the second motor torque command value. The active guiding control of the independent rotating wheel is realized by controlling the output torque of the traction motor, and the control process is simpler.
