Embodiment Construction
[0008] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0009] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0010] like figure 1 As shown, a method for optimizing the speed regulator of the drive motor under AMT gear shifting of an electric vehicle. When the electric vehicle is automatically shifting gears, the reference speed ω*m is given by the vehicle controller VCU, and is fed back by the encoder 4. The actual speed ωm is compared to obtain the speed difference of the control signal. Through the speed loop PI regulator, the torque command that needs to be adjusted is output for speed regulation unt...
