Exam 22: Hybrid Transmissions

The torque smoothing feature is especially helpful on eight-cylinder hybrid vehicles.

Idle stop is one of the most common functions that a hybrid vehicle performs.

Tech A states that the Prius drive system only uses electric motors to propel the vehicle in reverse. Tech B states that the Prius drive system uses a small planetary gear set for reverse. Who is correct?

Which of the following features is used in Mode 2 of a two-mode hybrid to achieve fuel savings?

Belt alternator starter (BAS) vehicles have been produced primarily by the General Motors Corporation.

Which of the following can be used in a hybrid vehicle to generate electricity to charge the high-voltage battery?

Belt Alternator Starter (BAS) vehicles cannot provide regenerative braking.

How are Toyota and Lexus hybrid systems classified?

Which of the following hybrid systems cannot drive the vehicle by using only the electric motor only?

In a hybrid vehicle, the water pump and air-conditioning compressor are typically driven by an engine drive belt.

Which of the following hybrid systems cannot drive the vehicle by using only the electric motor only?

Technician A says that all hybrid vehicles use the same transmission as a non-hybrid vehicle. Technician B says that some hybrid transmissions have a small electric fluid pump for when the transmission is in idle/stop mode. Who is correct?

Which of the following is NOT needed to service a hybrid vehicle?

Conventional starter motors and alternators in non-hybrid vehicles typically operate on 42 volts, while the Belt Alternator Starter (BAS) hybrid system uses a 12-volt battery.

The Honda ____________system can be used with a conventional automatic transmission, a manual transmission, or a continuously variable transmission (CVT).

Because either the gasoline engine or the electric motor/generator can propel the vehicle, or both can be used together, how are Toyota and Lexus hybrids classified?

Technician A says that parallel hybrid systems use transmissions that allow both the internal combustion engine and electric motor to drive the wheels at the same time. Technician B says that all hybrid systems use a variable pulley diameter continually variable transmissions to connect the internal combustion engine to the electric motor. Who is correct?

Technician A says that the Honda IMA system uses a thin electric motor between the engine and the transmission. Technician B says that the Honda IMA system uses battery voltages between 144 and 158 volts. Who is correct?

The regenerative braking system makes hybrids ideal for delivery vehicles and city transit buses that operate in stop-and-go conditions all day long.

At approximately what speed does a hybrid vehicle switch from electric-only propulsion to a mode that uses both electric and internal combustion engine propulsion?
