Example Embodiment

[0024] Referring to the drawings, where the same reference numerals represent the same parts in several figures, figure 1 A hybrid electric vehicle 10 is schematically shown, having a first axle 12 connected to a first pair of wheels 14 and a second axle 16 connected to a second pair of wheels 18. In one embodiment, wheel 14 is the front wheel and wheel 18 is the rear wheel. in figure 1 In this, the wheels 14, 18 are shown with tires 19 attached. Each axle 12, 16 has two separate axle parts, which are connected via corresponding differentials 15, 17, which can be easily understood by those skilled in the art. Each wheel 14, 16 has a friction brake mechanism 20, shown as a disc brake. The first axle 12 may be connected to the hybrid electric transmission 22 and the second axle 16 may be connected to the electric drive module 24. The hybrid electric transmission 22, the engine 26, the energy storage device 70, the controller 64, and the electric drive module 24 together establi...

Abstract

A hybrid vehicle is provided with an electric transmission operatively connected to a first axle and an electric drive module operatively connected to a second axle. A transmission ratio of a differential gear set and a final drive of the electric transmission are selected so that a torque ratio of torque of the first axle over the torque of the engine is that at which any working chamber of the engine that is operated to expand the working fluid can operate without throttling, without torque of the engine torque exceeding a torque necessary to propel the vehicle at a steady vehicle speed, and with the second electric machine freewheeling.

Description

technical field [0001] The invention generally includes hybrid vehicles configured for efficient engine performance. Background technique [0002] A vehicle may be equipped with one or more front wheels and one or more rear wheels. The vehicle may be equipped with an engine that produces shaft power to propel the vehicle. Vehicles may be equipped with a transmission for converting shaft power from an engine output—relatively low torque and high speed—to relatively high torque and low speed to drive one or more wheels. Vehicles may be equipped with axles for transmitting shaft power from both transmissions to one or more wheels. It is advantageous, especially in relation to mechanical simplicity, to use the engine, transmission and axles to drive only the front wheels or only the rear wheels. It is advantageous, especially in relation to operation in various environmental conditions, to drive all wheels. [0003] The forces that propel a wheeled vehicle at a steady speed ...
