Description

Imperial Units

Metric Units

Driver model wagon-tongue steer option inputs.

(must be supplied if IWAGN = 1 (card 402, field 2))

405:1

TPRB

Initial probe sample time.

sec

405:2

DPRB

Time between probe samples.

sec

405:3

PLGTH

Length of probe from vehicle C.G. extending along vehicle-fixed longitudinal (X) axis.

in

405:4

PMIN

Error correction null band. If error of probe from path is ≤PMIN, no corrective steer will be applied.

in

405:5

PMAX

Maximum acceptable comfort factor above which driver model will only reduce front-wheel steer angle.

g’s

405:6

PSIFD

Maximum front-wheel steer velocity. Corrective steer response will be limited to ≤ PSIFD.

deg/sec

405:7

PGAIN

Steer correction factor. Error is multiplied by PGAIN to determine corrective steer.

rad/in

405:8

QGAIN

Steer velocity damping term. Limits velocity with which front-wheel steer angle can change.

rad-sec/in
