Embodiment Construction

[0041] The present invention relates generally to vehicles, but more particularly to passenger vehicles sized to accommodate between 2 and 9 passengers, or between 2 and 5 passengers, including a driver.

[0042] Figure 1 is a schematic diagram of a prior art solution for a vehicle 1000 comprising a hybrid electric drivetrain 1003 and a battery pack 1002 electrically connected to an electric propulsion motor 1001 which in turn is directly connected to the vehicle The transmission 1003 is used to propel the vehicle by converting electrical energy into mechanical motion. Furthermore, it provides an internal combustion engine (ICE) 1005 also directly connected to the vehicle transmission 1003 by means of a clutch 1006 for propelling the vehicle by converting liquid fuel into mechanical motion.

[0043]Furthermore, the internal combustion engine 1005 is directly connected to a generator 1007 which in turn is electrically connected to the battery pack 1002 and the power electronics...

Abstract

There is provided a hybrid electric vehicle comprising an engine (101) and only one electric machine (102) mechanically coupled to the gear system (100) for propelling the vehicle, wherein the maximum power of said electric machine (102) is greater than the maximum power of said engine (101). Further, the same mechanical path is used for providing mechanical motion to the transmission system (100) by said engine (101) and electric machine (102), as is used for receiving mechanical motion at said electric machine (102) for charging the energy storage device (123).

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles. More particularly, it relates to a hybrid electric vehicle comprising an engine, an electric machine and an energy storage device electrically connected to the electric machine. [0002] Background of the invention [0003] To reduce fuel consumption and CO 2 emissions, combining the electric motor (EM) and internal combustion engine (ICE) in hybrid electric vehicles is becoming common. When designing such a vehicle, a number of requirements must be met. For example: consumer demand for vehicle handling flexibility and performance, government regulations to control emissions from different energy sources, cost constraints, vehicle design to appeal to potential markets, while the vehicle body also limits the placement of propulsion systems and transmissions system space. [0004] The GETRAG group of companies has released a hybrid electric vehicle transmission that can be directly conne...
