Abstract

A hybrid transmission for a vehicle includes a transmission input shaft extending in a transverse direction, at least one countershaft arranged parallel to the transmission input shaft, a clutch device arranged coaxially with respect to the transmission input shaft and which has at least one clutch, and a differential having a differential input gear. A rotational axis of the differential input gear is arranged parallel to the transmission input shaft. The transmission also includes an electric machine having a rotor with a rotor rotational axis arranged parallel to the transmission input shaft and a transmission control device. As viewed in a longitudinal direction perpendicular to the transverse direction, the differential input gear, the transmission input shaft, and a transmission controller including the transmission control device are arranged in succession in the sequence specified.
