During the period of increasing the rotational speed, detect that the assist motor current of the vehicle is less than or equal to the no-load current.

[0043] (9) Assist ratio test: Load different damping through the drum servo motor 32 connected to the rubber-coated drum 31 to simulate different slopes.
