Driving motor speed regulator optimization method used in electric vehicle AMT gear changing

The invention discloses a driving motor speed regulator optimization method used in electric vehicle AMT gear changing. Cooperative work of a speed ring controller and an acceleration sensor is adopted in a speed ring PI regulator; an acceleration value a in current driving of a vehicle is obtained through the acceleration sensor; next, comparison between the acceleration value a output by the acceleration sensor and a preset acceleration threshold value K is performed; when the acceleration value a is less than or equal to the acceleration threshold value K, the output of the speed ring PI regulator is not adjusted, equivalently, the proportional element of the speed ring is output as normal; and when the acceleration value a is greater than the acceleration threshold value K, the proportional element output value is subjected to amplitude limiting by the integral element output value of the speed ring. By virtue of the driving motor speed regulator optimization method, the acting intensity of the proportional element can be lowered according to the current acceleration condition in vehicle gear changing, so that overshoot of a rotary speed ring is suppressed effectively, and a quick, accurate and smooth gear changing experience can be realized.
