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.

Abstract: The present invention provides an apparatus and method for controlling an accelerator for electric vehicles. The method comprises steps of: acquiring an actual accelerator pedal depth value and a current vehicle speed; determining a maximum output torque of motor under the current vehicle speed based on the current vehicle speed; and controlling the output torque of motor in such a way that the growth rate of the output torque higher than that of the actual accelerator pedal depth value at the beginning and then closed to that of the actual accelerator pedal depth value during the actual accelerator pedal depth value growing. The invention makes the output torque grown rapidly within the shallow range of accelerator pedal depth, while makes the output torque grown closed to that of the accelerator pedal depth within the relative deep range of accelerator pedal depth. Thus during the initial stage of acceleration, the vehicle may rapidly output a bigger torque, with an excellent dynamic response, to improve the driving comfort.
