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

• To reduce the friction between the tyre and the road

• To adjust the camber angle of the wheel during steering

What is the function of stability assist in a vehicle?

• Increases lateral acceleration during cornering

• Actively influences vehicle driving dynamics under vehicle limit conditions

• Monitors the temperature of the brake system

• Reduces the yaw rate of the vehicle

What is the effect of under-inflated tyres on vehicle tracking?

• Wear on one tyre and one edge only

• Wear on both tyres

• Wheel imbalance

• Suspension defects, feathering

What is the purpose of the Ackermann steering geometry?

• To adjust the camber angle of the wheel during steering

• To increase the stability of the vehicle in straight line situations

• To solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii

• To measure the lateral acceleration of the vehicle

What is the traction slip dependent on?

• The vehicle speed

• The lateral acceleration

• The cornering force

• The power being transferred

What is the yaw rate dependent on?

• The effective yaw moment and the vehicle mass

• The lateral acceleration and the vehicle speed

• The steering angle and the wheel speeds

• The cornering force and the lateral acceleration

What is the purpose of brake traction control system?

• To actively influence vehicle driving dynamics under vehicle limit conditions

• To measure the brake pressure in the hydraulic system

• To initiate braking of the slipping wheel with the aid of the brake system

• To reduce engine power in the event of high traction slip
