The invention discloses a control method and a control device for a turning angle of a vehicle steering wheel. The method comprises the following steps: determining a target steering wheel angle; acquiring an actual steering wheel angle; determining a target steering wheel angular velocity based on the target steering wheel angle and the actual steering wheel angle; acquiring an actual steering wheel angular velocity; calculating by taking the difference between the target steering wheel angular velocity and the actual steering wheel angular velocity as the input of a PID control algorithm; providing a first feed-forward torque based on a difference between the target steering wheel angular velocity and the actual steering wheel angular velocity and the actual steering wheel angular velocity; providing a second feed-forward torque based on the target steering wheel angular velocity and the actual steering wheel angle; and calculating a target steering motor torque based on a calculation result of the PID control algorithm, the first feed-forward torque and the second feed-forward torque.
