Answers
1
ASC assists in....
applying brake effect to individual wheels
reduce engine torque to prevent wheels spinning
assists when accelerating on slippery surfaces
improved stability of vehicle
2
ESC is able to...
worsen vehicle stability by braking indivudual wheels
predict when vehicle may under or over steer
completely prevent collisions
override the laws of physics
3
what does EBA stand for
emergency brake assist
engine brake assist
engine bulb adaptor
emergency brake assessor
4
what does EBD stand for?
engine brake distribution
electronic brake force distribution
emergency brake distance
electric brake distance
5
retarder systems help keep brake temperatures LOW and can help reduce overall stopping distance
False
True
6
ESC works in a similar way to ASR?
False
True
7
what is the purpose of EBD
reduce stopping distances when braking
passenger comfort
improve vehicle handling while braking
8
what does ASC stand for?
acceleration skid control
acceleration slip control
anti skid control
anti slip control
9
ABS is designed to be a technical equivalent to 'cadence breaking'
False
True
10
what does ABS do?
driver will not skid during harsh breaking
allows driver to break later than normal
enables driver to drive without pushing the accelerator
enables driver to steer/brake without wheels locking during harsh breaking
11
when does EBA come into effect?
when the brake pedal is pressed quickly
when the driver presses a button
it is always in effect
when the brake pedal is pressed slowly
12
EBD will detect which wheel has more or less grip and change braking force
True
False
13
if EBA malfuctions what will happen?
stopping distance may reduce
vehicle will not have full brake effect
vehicle will still have its full brake effect
nothing
14
overall stopping distance is...
braking distance - thinking difference
however big or small the driver sees it
braking distance + thinking distance
thinking distance X braking distance
15
EBA automatically reduces brake pressure and reduces stopping distance
False
True
16
when does EBA come into effect?
when the break pedal is pressed quickly
it is always in effect
when the driver presses a button
when the break pedal is pressed slowly
17
cruise control can...
improve fuel economy
reduced fuel economy
make a car look fancier
completely take over braking even in emergency settings
18
what does ESC stand for?
engine service command
electronic skid control
electronic stability control
eggs sugar cream
19
what does a lane depature warning system do?
tells driver when lane is free to drive in and overtake vehicle infront
allows driver to chill out and reduce concentration
detetcs if vehicle strays away from lane it is travelling in
20
why should high brake temperatures be avoided?
leads to brake fade and wear
increases maintence costs
warning lights will constantly flash and distract drivers
increases vehicle downtime
21
Retarders....
do not help with passenger comfort
are often fully automatic and requires no additional input from the driver
does require special training to be used before
do not slow down the vehicle at any speed
22
if the ABS light maintains lit, there is nothing wrong with the system and the vehicle does not need to be checked
True
False
23
retarders are often fitted to smaller vehicles
True
False
