An electric drive system control method, comprising: according to a vehicle state parameter, determining that a vehicle is in a driving working condition; in response to a vehicle heat compensation requirement signal, obtaining a rotational speed value, a shaft end torque value, a current direct axis current value, and a current quadrature axis current value of a motor; determining a target torque curve according to the shaft end torque value, and determining a target driving heating calibration curve according to the vehicle heat compensation requirement and the rotational speed value; taking an intersection of the target torque curve and the target driving heating calibration curve as a target driving working condition point; determining a target quadrature axis current value and a target direct axis current value according to the target driving working condition point; and according to the target direct axis current value and the target quadrature axis current value, controlling the motor to operate. Also disclosed are an electric drive system and a vehicle.
