Embodiment Construction

[0036] Referring to the drawings, wherein like numerals represent like parts throughout the several views, in figure 1 A driveline 40 of a vehicle 42 is schematically shown in FIG. Generally, the vehicle 42 includes an internal combustion engine 44 including a crankshaft 46 such as figure 1 shown. In such embodiments, vehicle 42 may be referred to as a hybrid electric vehicle (HEV), plug-in hybrid vehicle (PHEV), or the like. Such HEV vehicles, PHEV vehicles, etc. may be referred to as dedicated hybrid vehicles. In such an embodiment, the vehicle 42 is propelled by an internal combustion engine 44 and / or electric power, as described in further detail below. In embodiments where the vehicle 42 does not include an internal combustion engine, the vehicle 42 may be referred to as a battery electric vehicle (BEV), as Figure 20 shown schematically in. In such an embodiment, only electric power is used to propel the vehicle 42 .

Abstract

A transmission system includes a transmission housing and a countershaft having no less than two gears, with the gears defining a plurality of gear ratios. The transmission system also includes a module housing, a first output shaft rotatably coupled to the countershaft, and a second output shaft rotatably coupled to the countershaft. The transmission system further includes a first clutch configured to selectively rotatably couple the first output shaft to the countershaft. The transmission system also includes a second clutch configured to selectively rotatably couple the second output shaftto the countershaft. The transmission system further includes an electric machine configured to deliver rotational power to at least one of the first and second output shafts to deliver rotational power to the countershaft. The countershaft is rotatably coupled to either of the first and second output shafts for all of the gear ratios.

Description

technical field [0001] The present disclosure generally relates to a transmission system for a vehicle and a method of controlling the transmission system. Background technique [0002] A conventional vehicle includes an internal combustion engine and a driveline for delivering rotational power to the wheels of the vehicle. In recent years, there has been a desire to improve the fuel efficiency of vehicles. [0003] To achieve this, some vehicles in recent years have included electric motors that are also capable of delivering rotational power to the wheels of the vehicle. Such vehicles are often referred to as hybrid vehicles. While hybrid vehicles generally have improved fuel efficiency when compared to conventional vehicles, hybrid vehicles, and specifically, the drivetrains of hybrid vehicles, generally cost more money, require increased engineering design costs, and increase the efficiency of the hybrid vehicle. weight. [0004] Accordingly, there remains a need to ...
