In this production Voltec (gen 1) powertrain, the internal combustion engine / range extender is on the left and the Voltec drive unit is on the right. The coiled bundle of orange high-voltage cables between the engine and drive unit connect the traction power inverter module (TPIM, on top) to the transaxle below (not visible).
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU).
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

A schematic representation of the power-train of a series hybrid vehicle. The engine is usually smaller than what would be required for powering a conventional petrol vehicle of the same size. The engine usually runs at its optimum high efficiency RPM, powering the generator. When extra power is needed for acceleration or for climbing gradients ...
This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the ...
The Toyota Hybrid System THS / Hybrid Synergy Drive has a single power-split device (incorporated as a single three-shaft planetary gearset) and can be classified as an Input-Split, since the power of the engine is split at the input to the transmission. This in turn makes this setup very simple in mechanical terms, but has drawbacks of its own.

The GT-300 was designed with a 3.5:1 compression ratio and nominal design turboshaft speeds of 24,000 RPM (gasifier) and 12,000 RPM (power). Engine accessories are driven by the gasifier turboshaft through a perpendicular bevel gear arrangement; a conventional automotive starting motor is used to crank the accessory drive shaft (and gasifier ...
