computeParameters()

void FirstOrderLagModel::computeParameters ( )

protected

Recomputes helper variables after loading parameters

Here is the caller graph for this function:

getRealAcceleration()

double FirstOrderLagModel::getRealAcceleration ( double  speed_mps, double  accel_mps2, double  reqAccel_mps2, SUMOTime  timeStep = 0  )

virtual

Computes real vehicle acceleration given current speed, current acceleration, and requested acceleration. Acceleration can be negative as well. The model should handle decelerations as well

Parameters

[in]	speed_mps	current speed in meters per second
[in]	accel_mps2	current acceleration in meters per squared second
[in]	reqAccel_mps2	requested acceleration in meters per squared second
[in]	timeStep	current simulation timestep

Returns

the real acceleration that the vehicle applies in meters per squared second

Implements GenericEngineModel.

loadParameters()

void FirstOrderLagModel::loadParameters ( const Parameterised::Map &  parameters )

virtual

Load model parameters. This method requires a map of strings to be as flexible as possible, independently from the actual model implementation

Parameters

[in]

parameters

a map of strings (from parameter name to parameter value) including configuration parameters
