The embodiment of the invention discloses a control method and device for electric power steering, a medium and equipment. The method comprises the following steps: acquiring an initial power-assisted characteristic curve of an electric power-assisted steering mode, wherein the electric power-assisted steering mode comprises a first mode, a second mode and a third mode; the slopes of the initial power-assisted characteristic curve of the first mode, the initial power-assisted characteristic curve of the second mode and the initial power-assisted characteristic curve of the third mode are gradually increased in sequence; determining a mapping relation between each power-assisted margin value of the current electric power-assisted steering mode in the power-assisted margin range and the power-assisted characteristic curve of the current electric power-assisted steering mode; and if a power-assisted margin adjusting event is detected, determining an adjusted power-assisted characteristic curve according to a power-assisted margin value selected by a user in the current electric power steering mode. According to the technical scheme, the adaptability of the electric power steering system can be improved on the premise that driving safety is guaranteed, and convenient and comfortable driving experience is provided for the driver.
