Member Function Documentation

◆ GetMaxSteeringAngle()

virtual double chrono::vehicle::citybus::CityBus_Vehicle::GetMaxSteeringAngle ( ) const

inlineoverridevirtual

Return the maximum steering angle.

This default implementation estimates the maximum steering angle based on a bicycle model and the vehicle minimum turning radius.

Reimplemented from chrono::vehicle::ChWheeledVehicle.

◆ GetMinTurningRadius()

virtual double chrono::vehicle::citybus::CityBus_Vehicle::GetMinTurningRadius ( ) const

inlineoverridevirtual

Return the minimum turning radius.

A concrete wheeled vehicle class should override the default value (20 m).

Reimplemented from chrono::vehicle::ChWheeledVehicle.

◆ Initialize()

void chrono::vehicle::citybus::CityBus_Vehicle::Initialize	(	const ChCoordsys<> &	chassisPos,
		double	chassisFwdVel = `0`
	)

overridevirtual

Initialize this vehicle at the specified global location and orientation.

Parameters

[in]	chassisPos	initial global position and orientation
[in]	chassisFwdVel	initial chassis forward velocity

Implements chrono::vehicle::ChVehicle.
