Exam 22: Hybrid Transmissions

Technician A says that some hybrid vehicle systems use very strong magnets that can pinch a finger, hand, or limb between the part and the magnet. Technician B says that a special tool may be needed to release a special magnet. Who is correct?

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

High voltage cables are always identified by an orange color conduit.

The harder the driver steps on the brake pedal of a hybrid vehicle, the more electricity is generated by the electric motor during the regenerative braking process.

All of the following statements are true except:

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?

Technician A says that some Continuously Variable Transmissions (CVTs) require a heating system to warm the transmission fluid during cold weather operation. Technician B says that CVTs are able to create an infinite number of gear ratios between their minimum and maximum ratio. Who is correct?

All of the following systems are considered as full hybrid that can be classified as a series-parallel hybrid except:

Which of the following refers to the ability of the hybrid vehicle to use an electric motor to help smooth out the power pulses of the ICE and create a flatter torque output curve?

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 hybrid functions allows manufacturers to reduce engine size while retaining performance similar to a large engine?

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?

Tech A states that hybrid vehicles use higher voltage than traditional cars. Tech B states that hybrid vehicles use one or more operating modes to achieve higher fuel economy. 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?

Mode 2 of a two-mode hybrid is used at low speeds and light engine load.

Tech A states that before performing service on some components on a hybrid vehicle it will be necessary to shut off the high voltage system. Tech B states that high voltage gloves must be worn when working on high voltage circuits. Who is correct?

Technician A says that some hybrid vehicle systems use very strong magnets that can pinch a finger, hand, or limb between the part and the magnet. Technician B says that a special tool may be needed to release a special magnet. Who is correct?

Tech A states that high voltage gloves should be replaced every year. Tech B states that high voltage gloves should be tested or replaced every 6 months. Who is correct?

Which of the following have led vehicle manufacturers to create newer, more efficient powertrain systems?

Which of the following is the most common type of continuously variable transmission (CVT) commonly used in production, non-hybrid vehicles?
