摘要： An electric spoiler control method. The electric spoiler control method comprises: acquiring the current position of an spoiler, and determining, according to the current position of the spoiler and a preset position of the spoiler, whether the spoiler is offset (S 1); when it is determined that the spoiler is offset, outputting an offset signal related to the offset of the spoiler (S2); when a confirmation adjustment signal for the offset signal is detected, controlling the spoiler to enter an spoiler self-learning state, wherein the spoiler self-learning state comprises controlling the spoiler to execute a preset learning action between a plurality of calibration positions (S3); and acquiring an actual position of the spoiler, and when it is detected that an offset value between the actual position and the corresponding calibration position is less than a preset offset value, determining that spoiler self-learning is successful (S4). Further disclosed are an electric spoiler control apparatus, and an electronic device, a vehicle and a computer program product, which include the control method. By means of the control method, the problem of it being impossible to correct the angle of an spoiler in time when the spoiler is offset is solved, thus effectively improving the applicability of the spoiler.

摘要： This wind power generation device includes a plurality of rotary blades 15 around a rotation axis. Each rotary blade 15 includes a front blade surface 16 parallel to the rotation axis and curved so as to protrude frontward in a rotation direction, and a rear blade surface 17 located on the back side of the front blade surface 16, being parallel to the rotation axis, being curved so as to be concave frontward in the rotation direction, and having a smaller curve depth than the front blade surface 16. The front blade surface 16 includes a first curved surface 19 forming a part far from the rotation axis and formed frontward in the rotation direction from an outer end 21 of the rotary blade 15, and a second curved surface 20 forming a part close to the rotation axis L1 and formed rearward in the rotation direction from a crest 18 of the front blade surface 16 so as to connect to an inner end 22, a surface length thereof in a plan view being smaller than that of the first curved surface 19. The first curved surface 19 has recesses 23 at positions closer to the outer end 21 than to the crest 18 of the front blade surface 16. Thus, a rotary blade that rotates by receiving a fluid and can improve rotation efficiency, is provided.
