A method for controlling an electric drive system, includes: determining that the vehicle is in a traveling condition; obtaining a rotation speed value, a shaft end torque value, a present direct axis current value, and a present quadrature axis current value of the motor when receiving a vehicle heat-up demand signal; determining a target torque curve according to the shaft end torque value, and determining a target traveling heating calibration curve according to the vehicle heat-up demand signal and the rotation speed value; determining an intersection of the target torque curve and the target traveling heating calibration curve as a target traveling condition point; determining a target quadrature axis current value and a target direct axis current value according to the target traveling condition point; and controlling, according to the target direct axis current value and the target quadrature axis current value, the motor to operate.
