Member Function Documentation

◆ GetDriveshaft()

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

inline

Get a handle to the driveshaft.

Return a pointer to the shaft that connects this driveline to a powertrain system.

◆ GetDriveshaftSpeed()

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

inline

Get the angular speed of the driveshaft.

This represents the output from the driveline subsystem that is passed to the powertrain system.

◆ InitializeInertiaProperties()

void chrono::vehicle::ChDriveline::InitializeInertiaProperties ( )

overrideprotectedvirtual

Initialize subsystem inertia properties.

Derived classes must override this function and set the subsystem mass (m_mass) and, if constant, the subsystem COM frame and its inertia tensor. This function is called during initialization of the vehicle system.

Implements chrono::vehicle::ChPart.

◆ UpdateInertiaProperties()

void chrono::vehicle::ChDriveline::UpdateInertiaProperties ( )

overrideprotectedvirtual

Update subsystem inertia properties.

Derived classes must override this function and set the global subsystem transform (m_xform) and, unless constant, the subsystem COM frame (m_com) and its inertia tensor (m_inertia). Calculate the current inertia properties and global frame of this subsystem. This function is called every time the state of the vehicle system is advanced in time.

Implements chrono::vehicle::ChPart.
