Exam 22: Hybrid Transmissions

In Toyota and Lexus hybrid vehicles, what is used to charge the high-voltage battery pack and to crank the engine over?

Which of the following transaxles can be used in combination with the integrated motor assist system?

Many full hybrid vehicles can operate at low speeds using the electric motor only. These cars typically begin using the internal combustion engine at _________.

Which of the following transmission designs do not use gears as a method of changing the torque / speed relationship between the input and output shafts of the transmission?

Technician A says that Belted Alternator Starter (BAS) vehicles use an alternator to help slow the vehicle and act as a starter. Technician B says that the BAS alternator can be used to propel the vehicle without the internal combustion engine. Who is correct?

Which of the following hybrid electrical systems uses a thin electric motor in place of a conventional flywheel or flex plate?

How is the high voltage battery recharged?

Two technicians are discussing two-mode hybrid vehicles. Technician A says the system uses 300 volts to power the two electric motor/generators housed inside the transmission case. Technician B says the two-mode hybrid uses three or four planetary gear sets, depending on the application. Who is correct?

Which of the following is a function of a hybrid system?

The only major difference between the Ford and the Toyota hybrid vehicles is that rather than having the two electric motor/generators directly connected to the ring gear and the sun gear, as they are in the Toyota vehicles, the Ford hybrids are attached through a set of ________.

When the ICE is on a compression pulse, what does the electric motor do to reduce crankshaft vibration?

The two-mode hybrid system was developed between General Motors, Chrysler and BMW for lightweight sub-compact cars.

Which of the following hybrid system functions allows the hybrid vehicle to use a smaller internal combustion engine and still perform like a non-hybrid vehicle with a larger engine?

During Mode 1 of a two-mode hybrid vehicle, only the gasoline engine is running to propel the vehicle.

Tech A states that all hybrid vehicles can operate on electric propulsion only. Tech B states that most hybrids utilize stop start technology to improve fuel economy. Who is correct?

Which of the following hybrid functions allows manufacturers to reduce engine size while retaining performance similar to a large engine?
