The embodiment of the invention provides a method for controlling a synchronous motor, electronic equipment and a vehicle. The method comprises the following steps: when the current rotating speed of the motor reaches or exceeds a threshold rotating speed, determining a coefficient factor changing along with the current rotating speed according to the current rotating speed of the motor; determining a proportional-integral parameter according to the coefficient factor; determining a direct-axis current deviation value and a quadrature-axis current deviation value; and determining a direct-axis voltage value and a quadrature-axis voltage value for controlling the motor according to the determined direct-axis current deviation value and quadrature-axis current deviation value and the proportional-integral parameter. By adopting a method for adjusting the bandwidth of a current loop according to the current rotating speed, when a given current value is tracked by a current implementation feedback value, disturbance interference on a cross decoupling item containing back electromotive force is weakened by adopting a segmented limit coefficient factor matching strategy, so that the influence of the high rotating speed on a control system is reduced, and the stability of the control system is improved. And the stability and robustness of the control system are ensured.
