Day 2 Flashcards
How much grip does the average tyre have on the road?
About the size of a hand
Moderate braking and accelerating leaves grip for … ?
Steering
Excessive braking and accelerating leaves less grip for … ?
Steering
As you brake on a straight, the weight of the car moves towards?
The front of the car
As you corner, the weight of the car shifts to … ?
The outside of the car towards the curve
If you corner and break, the weight of the car shifts to … ?
The outside of the car and the front of the car towards the kerb
As you corner and accelerate, the weight of the car shifts towards … ?
The outside (towards the Kerb) and back of the car
Braking or Accelerating round a corner leaves less room for … ?
Tyre grip, in turn reducing control of the car.
What does ESP stand for ?
Electronic Stability Programme
What does TCS stand for?
Traction Control System
What does ABS stand for?
Anti lock braking system
What happens to tyres’ grip when a car decelerates?
The front tyres gain grip and the rear tyres lose grip
What happens to the cars tyres when it accelerates?
Rear tyres gain grip and the front tyres lose grip.
What is Acceleration sense?
The ability to vary vehicle speed in response to changing road or traffic conditions by accurate use of the accelerator so that you brake less
When is a vehicle most stable?
When the vehicle is straight and the engine is pulling
What should you do when driving through water?
Left foot brake and maintain engine revs to ensure water does not go through the exhaust
When should you use brakes?
When you need to make more than a gradual adjustment to speed
Braking moves the weight of a vehicle … ?
Forward, to the front.
Does braking make steering heavier?
Yes
What is overall stopping distance?
Thinking distance + stopping distance
What is emergency braking ?
Pressing the brake as hard as you can for the ABS to kick in
What does the ABS allow you to do more effectively?
Steer
On slippery roads, how should you steer?
As delicately as possible
When manoeuvring, what should you do if you can’t get a full view of hazards
Exit the vehicle and or ask someone to check.
What should you be careful of when exiting a space ?
Overhangs (hitting other cars when steering to soon)
What should you do when parking on a hill?
Put the handbrake on, into gear with the wheels facing towards the kerb
What does the ABS do?
Applies brakes to individual wheels
ABS allows you to steer the vehicle when?
Under full braking power
Once you activate the ABS, what should you do?
Maintain maximum pressure on the brake pedal
How do you know when the ABS is activated ?
It should appear on the dash and you should feel the brake pedal vibrate or judder
What does traction control do?
Controls wheel spin
How does wheel spin occur ?
When the power given to the wheels exceeds the grip available by the wheels
What does ESP do?
Detect when a vehicle is off path and applies braking to individual wheels to correct steering
When do skids happen?
When one or more tyre loses grip causing involuntary movement of the vehicle
What things when driving causes skidding?
Braking, accelerating and cornering
How do you minimise skidding?
Checking tyre pressure and tread
When is skidding more likely to occur ? (Weather conditions)
In snow, ice, heavy rain and oil on the road .
What should you use in slippery conditions?
Low revs
What are the common causes of skidding?
Driving too fast for the circumstances, harsh acceleration, excessive or sudden braking and steering too sharply (coarse steering)
What is oversteer?
When the vehicle steers more then necessary
What is oversteer?
When the vehicle steers more then necessary
What is understeer?
When the vehicle steers less than anticipated
How do you reduce understeer?
By reducing power
What is aquaplaning ?
Occurs when a wedge of water gets between the front tyres and road surface
What should you do when aquaplaning?
Get off the accelerator.
