Abstract
Methods and systems for a dual motor transmission system that includes an intermediate shaft oriented parallel to both of a first shaft arranged with a first gear mesh, a third gear mesh, and a first low friction engaging device located between the first gear mesh and the third gear mesh and a second shaft arranged with a second gear mesh, a fourth gear mesh, and a second low friction engaging device located between the second gear mesh and the fourth gear mesh, a first electric motor coupled to the first shaft to enable a first reduction ratio and second reduction ratio of the first electric motor between the first shaft and the intermediate shaft, and a second electric motor coupled to the second shaft to enable a first reduction ratio and second reduction ratio of the second electric motor between the second shaft and the intermediate shaft.
