Function Documentation

applyBrakeToSpinVel()

tdble applyBrakeToSpinVel ( tdble spinVel, tdble brkTq, tdble inertia )

static

Integrate wheel/axle brake torque for one simulation step.

This helper encapsulates the common brake integration logic used in both spool and split-differential update paths.

Behavior details preserved from the original inline code:

• Brake torque opposes the current rotation sign (SIGN(spinVel)).
• If one integration step would cross through zero, the speed is clamped exactly to zero instead of changing sign.
• If speed is exactly zero and braking requests a negative step (possible because SIGN(0) is positive), the step is suppressed to keep standstill.

Parameters

[in]	spinVel	Current angular speed.
[in]	brkTq	Positive brake torque magnitude for this axis.
[in]	inertia	Effective rotational inertia used for integration.

Returns

Updated angular speed after applying brake integration for dt.
