Detailed Description

Helper methods for HBEFA4-based emission computation.

The parameter are stored per vehicle class; 6*6 parameter are used, sorted by the pollutant (CO2, CO, HC, fuel, NOx, PMx), and the function part (c0, cav1, cav2, c1, c2, c3).

Member Function Documentation

◆ compute()

double HelpersHBEFA4::compute	(	const SUMOEmissionClass	c,
		const PollutantsInterface::EmissionType	e,
		const double	v,
		const double	a,
		const double	slope,
		const EnergyParams *	param ) const

inline

Computes the emitted pollutant amount using the given speed and acceleration.

For most emissions the function yields mg/s. For fuel ml/s is returned if volumetric fuel has been requested. Coasting and an engine which is off by the given param result directly in zero emission.

Parameters

[in]	c	emission class for the function parameters to use
[in]	e	the type of emission (CO, CO2, ...)
[in]	v	The vehicle's current velocity
[in]	a	The vehicle's current acceleration
[in]	slope	The road's slope at vehicle's position [deg]
[in]	param	parameter of the emission model (only used for the coasting deceleration and to determine whether the engine is off)

Returns: The amount emitted by the given emission class when moving with the given velocity and acceleration [mg/s or ml/s]

◆ getAmitranVehicleClass()

std::string HelpersHBEFA4::getAmitranVehicleClass ( const SUMOEmissionClass c ) const

Returns the vehicle class described by this emission class as described in the Amitran interface (Passenger, ...).

Parameters

[in] c the emission class

Returns: the name of the vehicle class

◆ getClass()

SUMOEmissionClass HelpersHBEFA4::getClass	(	const SUMOEmissionClass	base,
		const std::string &	vClass,
		const std::string &	fuel,
		const std::string &	eClass,
		const double	weight ) const

Returns the emission class described by the given parameters.

Parameters

[in]	base	the base class giving the default
[in]	vClass	the vehicle class as described in the Amitran interface (Passenger, ...)
[in]	fuel	the fuel type as described in the Amitran interface (Gasoline, Diesel, ...)
[in]	eClass	the emission class as described in the Amitran interface (Euro0, ...)
[in]	weight	the vehicle weight in kg as described in the Amitran interface

Returns: the class described by the parameters

Parameters

[in] c the emission class

Returns: the Euro class

Definition at line 10123 of file HelpersHBEFA4.cpp.

◆ getFuel()

std::string HelpersHBEFA4::getFuel ( const SUMOEmissionClass c ) const
