REQUIREMENTS DEFINITION
BRV01
The front axle brake is automatically released if the function is allowed, the inactivation is timed for 1
second (without tilt) or 100ms (with tilt activated) after the function is disabled
VAR[TimerFrontAxleBrakeRelease] = M1s(CTRL[Drive] ≠ N & VAR[Tilt] = 0) | M100ms(CTRL[Drive] ≠ N &
VAR[Tilt] = 1)
REQUIREMENTS DEFINITION
BRV02
Front brake releasing is allowed (A) if all of the following conditions are satisfied :
VALIDATION A ENABLE CONDITIONS
0 Enable 1 1 Steering is running or running timer
REQUIREMENTS DEFINITION
BRV03
Front axle brake release is never inhibited (I): the function activation is controlled from the drive and
steering controls
REQUIREMENTS DEFINITION
BRV04
The rear axle brake is automatically released if the function is allowed, the inactivation is timed for 1
second (without tilt) or 100ms (with tilt activated) after the function is disabled
