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).

		const EnergyParams *	param
	)		const

inlinevirtual

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]
