A motor resolver assembly includes a resolver stator and a resolver rotor positioned radially inward of and rotatable with respect to the resolver stator. First and second relatively rotatable shield components generally surround the resolver stator and rotor to shield them from electromagnetic energy from a radially outward motor rotor and motor stator. A method of measuring speed and position of the motor rotor relative to the motor stator is also employed.

A dual path planetary transmission includes two planetary gearsets each having a sun gear member, a ring gear member, and a planet carrier assembly member. Each of the members of the planetary gearsets are selectively connectible between an input shaft, an output drive mechanism, and a stationary member. Each of the planetary gearsets is effective to provide a reverse ratio and five forward gear ratios. The output mechanism of each of the planetary gearsets includes a different gear ratio between the output mechanism and the transmission output shaft.

A hybrid transmission is provided that has both a hybrid series operating mode and a compound-split operating mode. The transmission includes an input member operatively connected with the engine, an output member, and a plurality of selectively engageable torque-transmitting mechanisms. A gearing arrangement and first and second motor/generators operatively connected with the gearing arrangement are also provided. The gearing arrangement includes a first, a second, and a third planetary gear set, each having a first, a second, and a third member. A pair of interconnecting members connect two respective ones of the members of one of the planetary gear sets for common rotation with two respective ones of the members of another of the planetary gear sets. Another interconnecting member connects a third of the members of the one of the planetary gear sets for common rotation with one of the members of still another of the planetary gear sets.

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.

An electro-mechanical drive unit connectable with multiple power sources for launching and propelling a vehicle includes an output member, a stationary member, and a torque-transmitting device. The drive unit also includes a compound planetary gear arrangement having a first, second, third, and fourth junction point. The power sources include a first motor/generator and a second motor/generator. The first motor/generator and the second motor/generator are disposed on a common rotating axis. The second motor/generator is operatively connected to the compound planetary gear arrangement at the first junction point and the output member is operatively connected to the compound planetary gear arrangement at the second junction point. Additionally, the first motor/generator is operatively connected to the compound planetary gear arrangement at the fourth junction point. Furthermore, the torque-transmitting device is engageable to ground the third junction point to the stationary member.

A method of operating a hybrid vehicle includes disengaging, i.e., turning off, an internal combustion engine when a brake pedal is disposed in a released position, i.e., non-depressed position, an accelerator pedal is disposed in a released position, i.e., non-depressed position, and a forward path of the hybrid vehicle is blocked, thereby conserving fuel. The method includes engaging, i.e., starting, the internal combustion engine when the brake pedal is disposed in the released position, the accelerator pedal is disposed in the released position, and the forward path of the hybrid vehicle is clear, thereby allowing for a quick launch of the vehicle.
