Question 1

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?

Accepted Answer

Technician B is correct because some hybrid vehicles use a small electric fluid pump to maintain hydraulic pressure in the transmission when the engine is off, such as during idle/stop mode. Hybrid vehicles often have different transmission designs compared to non-hybrid vehicles to accommodate electric drive components.

Accepted Answer

Toyota hybrids typically use an eCVT (electronic Continuously Variable Transmission) that does not have a separate gear for reverse and does not use a Variable Diameter Pulley system. Instead, they use a power-split device involving electric motors and a planetary gear set.

Question 8

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?

Accepted Answer

Toyota hybrids typically use an eCVT (electronically controlled Continuously Variable Transmission) that does not have a separate reverse gear and does not use a Variable Diameter Pulley system. Instead, it uses a power-split device involving electric motors to provide reverse motion.

Question 9

Technician A says that two-mode hybrid transmissions can use two electric motors to propel the vehicle. Technician B says that the two-mode hybrid transmission can use one motor to propel the vehicle and one to charge the battery. Who is correct?

Accepted Answer

Two-mode hybrid transmissions can indeed use two electric motors, where one can be used to propel the vehicle and the other can be used to charge the battery, making both technicians correct.

Question 10

Technician A says that two-mode hybrid transmissions can use two electric motors to propel the vehicle. Technician B says that the two-mode hybrid transmission can use one motor to propel the vehicle and one to charge the battery. Who is correct?

Accepted Answer

Two-mode hybrid transmissions can indeed use two electric motors where one can propel the vehicle and the other can charge the battery, making both technicians correct.

Question 11

Which of the following manufacturers uses a set of transfer gears inside their series-parallel hybrid transaxle to connect the two electric motors/generators to the internal combustion engine (ICE)?

Accepted Answer

Ford uses a set of transfer gears inside their series-parallel hybrid transaxle to connect the two electric motors/generators to the internal combustion engine (ICE).

Question 12

Technician A says Toyota and Lexus hybrid systems monitor battery voltage; if voltage is low, the internal combustion engine (ICE) is engaged. Technician B says Ford hybrid systems monitor battery voltage; if voltage is low, the ICE is engaged. Who is correct?

Accepted Answer

Both Toyota/Lexus and Ford hybrid systems monitor battery voltage and engage the internal combustion engine when the voltage is low to recharge the battery.

Question 13

The Honda IMA system is an example of the two-mode hybrid system.

Accepted Answer

The Honda IMA (Integrated Motor Assist) system is a mild hybrid system, not a two-mode hybrid system. Two-mode hybrids typically refer to systems that can operate in two distinct modes, such as full electric and hybrid, which is not the case with Honda's IMA.

Question 14

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

Accepted Answer

The Belt Alternator Starter (BAS) system uses a belt-driven alternator that also functions as a starter, allowing it to assist the engine and provide regenerative braking.

Question 15

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

Accepted Answer

Belt Alternator Starter (BAS) hybrid systems can provide both auto stop and regenerative braking by using the alternator to capture energy during braking and store it in the battery.

Question 16

Which of the following hybrid electric systems uses a thin electric motor located between the engine and transmission?

Accepted Answer

The Integrated Motor Assist (IMA) system uses a thin electric motor placed between the engine and transmission to assist with propulsion and regenerative braking.
