摘要: A method of controlling a vehicle including permanent magnet (PM) synchronous motor is provided. The calibrated such that for each torque command, there are corresponding direct-axis (d-axis) and quadrature axis (q-axis) current commands. includes establishing command T*. D-axis q-axis commands Id* Iq*, respectively, to the T* determined. controlled based on Iq*. currents Id Iq, measured. An output estimated as sum difference. difference determined function Id*, Id, Iq. may be torque.
