When the current flow reaches a certain amperage the relays kick in and start the engine. The voltage level of the batteries are also monitored and will also start and stop the engine when the baterries reach a certain level of charge. When you excelerate your electric motor draws more amps and voltage , which kicks on the gas motor. When you deceleratate the amp and voltage demand decreases so the gas engine is turned off.

The generator suddenly changes speed, causing the planet carrier to turn and start the engine. Once the engine is running, it settles into a constant speed while the generator varies its speed to match the output speed with the electric motor. If you are really accelerating hard, the motor will draw extra power from the batteries. Once you are up to freeway speed, the car will move under a combination of gas and electric power, with all of the electricity coming from the generator.
