CHP Academy EVOC Terms


Terms in this set (...)

*The lowest portion of the vehicle's path through a curve
Anti-lock brake system(abs)
Computer controlled brake system to prevent wheel lock-up under heavy braking.
Balanced-hand position
Maintain a wide grip on the steering wheel
*Brake fade
*The loss of brake efficiency normally due to heat build-up resulting from excessive use.
Centrifugal force
Center fleeing-pulling away from the center.
Centripetal force
Center seeking
Code 3
Operating with red light and siren in compliance with section 21055 CVC
*Coefficient of friction
*The measurement of cohesion between two surfaces
The sticking power between two surfaces.
*Turning the front wheels in the direction that the rear of the vehicle is sliding.
*Front-end swing
*When backing to the left, the front end will swing to the right. When backing to the right, the front end will swing to the left.
*High side
*The outside of a curve
The tire rides upon water rather than the roadway surface.
Kinetic energy
The energy possessed by a body in motion.
A body in motion will remain in motion in a straight line and at a constant velocity unless acted upon by an external unbalanced force.
*The characteristic of a vehicle to tighten it's turning radius as the rear end slips or skids toward the outside of the curve.
Potential energy
Energy a body possesses by virtue of its position or by virtue of displacement.
Power slide-four-wheel drift
The controlled lateral skidding of a vehicle when the limits of cohesion are exceeded by all four tires.
*Rear-end cheat
*While driving forward and turning left, the rear tires track to the left of the front tires. When turning right, the rear tires will track to the right of the front tires.
*Rolling friction
*The fact that the front wheels of the vehicle must be rolling in order to steer the vehicle.
Space cushion
The open area surrounding the vehicle while driving. An "escape route" to the front, rear and sides.
*Threshold braking
*Application of braking force to the point just prior to wheel lock-up. More efficient at slowing a vehicle than locked-wheel braking.
Gas pedal, accelerator
*Time spatial judgement, rate of closure
*Being able to judge the proper rate or deceleration necessary to negotiate a curve or avoid a hazard.
Tire footprint
The contact area of a tire tread with the roadway
*The tendency of a vehicle to continue in a straight line and resist turning from a direct course of travel.
*Visual horizon
*The distance a driver is looking ahead
*Weight transfer
*Acceleration causes the weight to go to the rear axle. Braking or deceleration causes weight to transfer to the front axle. Turning right transfers weight to the left and turning right transfers weight to the right.
*Slip angle
*The turning radius of the vehicle becomes larger as the contact patch of the tire is distorted by increasing cornering force.
