EVOC Flashcards
Anti-lock brake system
Computer controlled brake system designed to prevent wheel lock-up during heavy braking
Apex
The lowest portion of a vehicle’s path through a curve
Balanced hand position
Maintaining a wide grip on a vehicle’s steering wheel
Brake fade
The loss of braking efficiency normally due to heat build-up resulting from excessive use of brakes
Countersteer
Turning the front wheels of a vehicle in the direction the rear of the vehicle is sliding
Front end swing
The action of the front end of the vehicle when backing: the front-end swings to the right when backing to the left; the front end swings to the left when backing to the right
Oversteer
The characteristics of a vehicle to tighten its turning radius as the rear end slips or skids toward the outside of a curve
Rear end cheat
When turning left, a vehicle’s rear tires track to the left of the front tires. When a vehicle is turning right, the rear tires track to the right of the front tires
Rolling friction
The front wheels of the vehicle must be rolling, thereby creating rolling friction, in order to steer the vehicle
Slip angle
The turning radius of a vehicle becomes larger as the contact patch of each tire is distorted by increasing cornering force
Threshold braking
Application of braking force to the point just prior to wheel lock-up. The braking technique is more efficient at slowing a vehicle than locked-wheel braking
Time spatial judgement
Judging the proper rate of deceleration necessary to successfully negotiate a curve or to avoid a hazard
Understeer
The tendency for a vehicle to continue in a straight line and resist turning from a direct course of travel
Visual horizon
The area and distance viewed by the. Driver of a vehicle when looking ahead. High visual horizon is always optional
Longitude weight transfer
Weight transfer to the front axle of a vehicle caused by braking or deceleration
