Differential twin-engine automobile electric drive

Abstract

Abstract This article considers work stability of a system with two-channel regulation of an autonomous electric drive’s speed, where the first channel is a high-torque drive, where the engine is connected through a gear unit with reducing transfer factor; and the second – high-speed with the similar motor is directly connected. The power summation is realized by using the differential gear unit. It is shown that the stable work can be achieved by a fixation of a speed setting through one channel, and the regulation through the other channel at the same time; control algorithms are shown. Optimal values of transmission ratio of high-torque drive gear unit j = 4 are defined, as well as a turn-on factor (rate of participation in transient process) of high-torque motor with its transient process time minimum.
