Exam 22: Hybrid Transmissions

Tech A states that hybrid vehicles use high voltage to power the traditional starter motor to allow it to crank the engine over faster. Tech B states that some hybrids will have two starter motors, one high voltage, one 12 volts. Who is correct?

How are Toyota and Lexus hybrid systems classified?

All of the following statements are true except:

Which of the following occurs during idle stop?

Technician A says that the transmission in a Toyota hybrid has a separate gear to provide reverse. Technician B says that Toyota hybrids use a Variable Diameter Pulley (VDP) type Continuously Variable Transmission (CVT). Who is correct?

Which of the following hybrid electric systems uses a belt-driven alternator that also doubles as a starter?

Ford advertises their Continually Variable Transmissions (CVTs) as two-speed CVTs.

Tech A states that high voltage wiring will be encased in color coded conduit to identify the high voltage. Tech B states that many connectors on hybrids will have an interlock system built in that will turn off the high voltage system if the connector is unplugged. Who is correct?

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?

What is used to prevent a delay in the engagement of the transmission when the hybrid vehicle engine is restarted from idle stop?

Honda's integrated motor assist (IMA) system can be used with a conventional automatic transmission, a manual transmission, or a continuously variable transmission (CVT).

Which of the following is the voltage used by a Honda integrated motor assist (IMsystem?

Hybrid vehicles are classified as mild or full hybrid based on the:

In Toyota and Lexus hybrid vehicles, through what part are each of the electric motor/generators and the Internal Combustion Engine (ICE) connected?

Technician A says that a technician should always refer to the appropriate service information before attempting any hybrid vehicle repairs. Technician B says that the repairs to a hybrid vehicle are the exact same as an internal combustion engine vehicle, and that there are no special safety procedures that need to be followed. Who is correct?

Technician A says that a technician should always exercise extreme caution when working on and around hybrid vehicles because the high voltages used can cause serious harm and death. Technician B says that a technician should work on a hybrid vehicle only after they have received the proper training and understand the system and its operation. 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?

Which of the following is the voltage used by a Honda integrated motor assist (IMsystem?

Belt Alternator Starter hybrid systems are capable of auto stop but cannot provide regenerative braking.

Which of the following transmissions has no fixed gear ratios?
