    摘要: 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.

    摘要: This invention involves in electric motor field, providing a method and an apparatus for electric vehicle motor control and rotor position detection and fault-tolerance processing. The method comprises the following steps: detecting a current correct rotor position angle during a current sampling cycle; comparing said current correct rotor position angle with a calculated previous sampled rotor position angle and getting the difference between the current correct rotor position angle and the calculated previous sampled rotor position angle; determining whether the difference exceed a specified rotor angle limit maximum or not; if it exceeds, discarding the current correct rotor position angle, and computing the sum between the calculated previous sampled rotor position angle and the specified rotor angle limit maximum, and using the sum as a correcting value to control the motor motion. Thus, the invention resolves the problem in the prior art, that when an error rotor position appears, and the motor is continually controlled, this can lead to an overly large electric current resulting in damage to power components.
