HYBRID VEHICLE WITH ELECTRIC TRANSMISSION AND ELECTRIC DRIVE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a hybrid vehicle configured for obtaining efficient engine performance.SOLUTION: A hybrid vehicle 10 is provided with an electric transmission 22 operatively connected to a first axle 12 and an electric drive module 24 operatively connected to a second axle 16. A transmission ratio of a differential gear set 40 and a final drive 50 of the electric transmission 22 are selected so that a torque ratio of the torque of the first axle 12 over the torque of an engine is that at which any working chamber of the engine 26 that is operated to expand a working fluid can operate without throttling without the torque of the engine torque exceeding torque necessary to propel the vehicle 10 at a steady vehicle speed, and with a second electric machine 80 in a freewheeling state.
