CERAD EXAM 2/3 -Using in Car Technology

Question 1

HWC Rule 149 - Phones

Answer 1

You MUST exercise proper control of the vehicle and MUST NOT use a hand-helf phone or similar device unless making 112 or 999 call in an emergency

Question 2

When to use fog lights?

Answer 2

Visibility is 100m or less

Question 3

What is active saftey featurs and 3 examples?

Answer 3

Saftey Systems active prior to a crash
ABS, TCS, ESP

Question 4

What is the function of ABS? How does it work?

Answer 4

Allows for steering during hard/Emergency breaking.

Detects when a wheel is slowing and about to skid and releases the breaking at that wheel

Question 5

Does ABS reduce stopping distance?

Answer 5

No, may increase or decrease depending on other factors

Question 6

what is EBA?

Answer 6

Emergency Brake assist
When brakes applied with speed and foce, EBA cuts in and applies additional maximum force until ABS takes over, reducing stopping distance

Question 7

what is AEB

Answer 7

Autonomous Emergency Brake.

Function is vehicle specific, consult manual

Question 8

TCS?

Answer 8

Traction control system
Controlls excess spin on individual wheels by using braking and limiting engine output in some cases.

Reduce power of TCS engages

Question 9

ESP?

Answer 9

Electronic Stability Control

Incorperates TCS and ABS to maintain stability when the vehicle is being driver at its maximum cabilitities.

Sesnors on wheels work with yaw sesnor (rotation and pitch). If sensors detec the vehicle isnt following its intended path, it applies individual brakes to correct under or oversteer

Question 10

Seat Belt Checks (5)

Answer 10

• Check the webing for cuts and damage
• Over shoulder, flat over sternum to opposite hip with no twists.
• Seat belt adjuster 25-50mm abover shoulder
• Test inertia mechanism
• No objects between belt and person

Question 11

Passive saftey Systems that benefit from correct use of a seatbelt

Answer 11

Airbags
Seatbelt
Side Impact protection
Passenger Cell Protection
Steering Column design
Whiplash Protection System
Head Restraints
Crumple Zone

Question 11

Define Passive Saftey System

Answer 11

A system that prevents injury in the event of a crash

Question 12

EBD?

Answer 12

Electronic Brake force distribution

Varries breaking foce to reduce skidding

Question 13

Retarder?

Answer 13

Slows vehicle down using electromagnetic forces, reducing work on breaks and redces likleyhood of overheating.

Question 14

ASR and ASC?

Answer 14

Types of TCS

Acceleration Skid Control
Anti-slip regulator

Question 15

What can cruise control help with?

Answer 15

• Reducing fatigue
• Improving fuel economy
• Maintaining speed limits

Question 16

Adaptive Cruise control?

Answer 16

Cruise control that can adapt to vehicles in front or behind and maintaina safe speration distance.
