What is oversteer in vehicle dynamics?
When a car becomes unstable in a turn
When a car skids sideways
When a car turns less than commanded by the driver
When a car turns more than commanded by the driver
What is the purpose of traction control with engine management intervention?
To reduce engine power in the event of high traction slip
To increase engine power in the event of high traction slip
To apply brakes to the slipping wheel
To monitor the temperature of the brake system
What is the effect of positive caster angle on a vehicle's steering?
Gives no feedback to the driver in terms of wheel position
Provides easy steering input without instability
Reduces stability in straight line situations
Increases stability in straight line situations
What is the purpose of the scrub radius in steering geometry?
To measure the distance between the king pin axis and the centre of the contact patch of the wheel
To increase the effort needed to turn the wheel

What is the traction slip dependent on?
The vehicle speed
The lateral acceleration

The power being transferred
What is the yaw rate dependent on?
The effective yaw moment and the vehicle mass

What is the effect of positive camber on a vehicle's wheel?
The top of the wheel is more protruding than the bottom
The tyre becomes increasingly unable to transfer more power
The top of the wheel is inward
The tyre does not turn on its centreline

Signals from the steering angle and yaw rate sensors
The presence of traction slip based on the different wheel speeds
The rotational speed around the vertical axis of the vehicle
The centrifugal force arising in a curve
What is the effect of negative caster angle on a vehicle's steering?
Gives no feedback to the driver in terms of wheel position
Increases stability in straight line situations
Reduces stability in straight line situations
Provides easy steering input without instability
What is the purpose of the stability assist sensors?
To detect the actual vehicle behaviour
