Member Function Documentation

◆ Initialize()

virtual void chrono::vehicle::ChDrivelineWV::Initialize	(	std::shared_ptr< ChChassis >	chassis,
		const ChAxleList &	axles,
		const std::vector< int > &	driven_axles
	)

pure virtual

Initialize the driveline subsystem.

This function connects this driveline subsystem to the specified axle subsystems.

Parameters

chassis	associated chassis subsystem
axles	list of all vehicle axle subsystems
driven_axles	indexes of the driven vehicle axles

Implemented in chrono::vehicle::ChShaftsDriveline8WD, chrono::vehicle::ChShaftsDriveline6WD, chrono::vehicle::ChShaftsDriveline4WD, chrono::vehicle::ChShaftsDriveline2WD, chrono::vehicle::ChSimpleDrivelineXWD, chrono::vehicle::ChSimpleDriveline, chrono::vehicle::gator::Gator_SimpleDriveline, and chrono::vehicle::generic::Generic_SimpleDriveline.

◆ LockAxleDifferential()

void chrono::vehicle::ChDrivelineWV::LockAxleDifferential	(	int	axle,
		bool	lock
	)

virtual

Lock/unlock the differential on the specified axle.

By convention, axles are counted front to back, starting with index 0 for the front-most axle.

Reimplemented in chrono::vehicle::ChShaftsDriveline8WD, chrono::vehicle::ChShaftsDriveline6WD, chrono::vehicle::ChShaftsDriveline2WD, and chrono::vehicle::ChShaftsDriveline4WD.

◆ LockCentralDifferential()

void chrono::vehicle::ChDrivelineWV::LockCentralDifferential	(	int	which,
		bool	lock
	)

virtual

Lock/unlock the specified central differential.

By convention, central differentials are counted from front to back, starting with index 0.

Reimplemented in chrono::vehicle::ChShaftsDriveline8WD, chrono::vehicle::ChShaftsDriveline6WD, chrono::vehicle::ChShaftsDriveline4WD, and chrono::vehicle::ChShaftsDriveline2WD.

◆ Synchronize()

void chrono::vehicle::ChDrivelineWV::Synchronize ( double torque )

virtual

Update the driveline subsystem.

The motor torque represents the input to the driveline subsystem from the powertrain system. The default implementation applies this torque to the driveline's driveshaft.

Reimplemented in chrono::vehicle::ChSimpleDrivelineXWD, chrono::vehicle::ChSimpleDriveline, chrono::vehicle::gator::Gator_SimpleDriveline, and chrono::vehicle::generic::Generic_SimpleDriveline.
