Abstract: The present invention discloses a method and apparatus for controlling a motor for an electric vehicle. The method and apparatus calculates the current acceleration a of the motor according to the detected rotor position values in real-time, and if the current acceleration a is greater than a predetermined forward acceleration a0, the output torque of the motor is decreased. If the acceleration a is less than a predetermined backward acceleration a1, then the output torque of the motor is decreased. Thus, when the vehicle travels from a normal road surface to a smooth road surface, the decrease or increase output torque may suppress the abrupt speed variations.

Abstract: This invention provides methods for electric vehicle motor control and rotor position detection and fault-tolerant processing. The rotor position signal sampled by the system is compared with the previous rotor position θ0. When there is a sudden change, the current position signal acquired is discarded. Instead, a fault-tolerant processing strategy for use during an error condition is employed where the previous sampled rotor position θ0 is used as a base to determine the corrected current rotor position angle Θ1′. Then the correcting value is used to control the electric motor. Thus, during the motor operation, when the detection of the motor rotor position is erroneous because of a sensor such as a revolver that may be interfered by external conditions such as electromagnetic fields or vibrations or when there is a breakdown in other related hardware components or transmitting circuits, the fault-tolerant processing methods of this invention can effectively prevent the motor from losing control and allow it to maintain its continuity and stability.
