The invention relates to a speed reducer with a straight gear differential mechanism, an electric driving system and an electric driving control method, the speed reducer comprises a frame body, a speed reducing mechanism and the differential mechanism, and the speed reducing mechanism transmits power of a power source to the frame body to enable the frame body to rotate around a first axis; the differential mechanism comprises a first output sun gear, a second output sun gear and a differential gear set, the differential gear set comprises a first differential planetary gear and a second differential planetary gear, and the second differential planetary gear is meshed with the second output sun gear and the first differential planetary gear; the control method comprises the steps that when the power source is closed, power transmission between the power source and the speed reducer is cut off; or, power transmission between one wheel and the speed reducer is cut off. According to the speed reducer, the high component density is achieved, the occupied axial space is reduced, the occupied axial space of the whole electric drive system is reduced, the design cost is reduced, and the electric drive control method can maintain high-speed running of wheels and reduce energy loss when a power source is closed.
