yaw velocity

IN ENT AN 110

E; abc

DEF AN 115

The rotational velocity of the vehicle about an axis fixed in the vehicle, lying in the nominal plane of symmetry, and vertical when the vehicle is upright. |b|

CONT AN 120

A number of reliable methods for measuring the yaw velocity are already available. A fiber gyro, for example, which works on the basis of a ring interferometer without moving parts, lends itself particularly well for use in production vehicles. |a| The yaw velocity can be used to determine whether cornering is stable or the car is approaching its performance limit. |c|

NOTE AN 125

Standards : SAE J670 and J1451 in 115; also ISO 8855, 1991.

SYN AN 130

1- yaw angular velocity |E; d|

2- yaw acceleration |E; e|

3- yaw rate |E; bdfg|

: 131

CONT 3: The yaw rate is a measure of how quickly the car changes course. |g|
