Member Function Documentation

std::shared_ptr<ChShaft> chrono::vehicle::ChDriveline::GetDriveshaft ( ) const

Get a handle to the driveshaft.

Return a shared pointer to the shaft that connects this driveline to a powertrain system (i.e., right after the transmission box).

virtual double chrono::vehicle::ChDriveline::GetDriveshaftSpeed ( ) const
virtual

Get the angular speed of the driveshaft.

This represents the output from the driveline subsystem that is passed to the powertrain system. The default implementation returns the driveline's driveshaft speed.

Reimplemented in chrono::vehicle::ChSimpleDriveline.

virtual void chrono::vehicle::ChDriveline::Initialize ( std::shared_ptr< ChBody chassis,
const ChSuspensionList suspensions,
const std::vector< int > &  driven_axles 
)
pure virtual

Initialize the driveline subsystem.

This function connects this driveline subsystem to the axles of the specified suspension subsystems.

Parameters
chassishandle to the chassis body
suspensionslist of all vehicle suspension subsystems
driven_axlesindexes of the driven vehicle axles

Implemented in chrono::vehicle::ChShaftsDriveline2WD, chrono::vehicle::ChShaftsDriveline4WD, and chrono::vehicle::ChSimpleDriveline.

virtual void chrono::vehicle::ChDriveline::Synchronize ( double  torque)
virtual

Update the driveline subsystem: apply the specified motor torque.

This 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::ChSimpleDriveline.
