FrictionMapInterface

Created by: Leonhard Hermansdorfer

Documentation: This class loads the friction map (_tpamap.csv) and the corresponding data (_tpadata.json) and provides an interface to fetch friction data for a requested position on the race track.

Naming of map and data file has to be consistent! Everything replaced by '*' has to be identical in

order to load correct data to a given map.

The following data must be available for the friction map: tpa_map: csv-file containing the map information (x,y-coordinates of each grid cell; '_tpamap.csv' located in inputs folder) tpa_data: json-file containing specific data for each grid cell (e.g. coefficient of friction); '_tpadata.json' located in inputs folder)

get_friction_singlepos(positions)

This function returns the friction value mue for a given position.

Inputs: positions: x,y coordinate(s) in meters from origin for position of requested friction value(s) [[x_0, y_0], [x_1, y_1], ...] (multiple coordinate points allowed)

Outputs: mue_singlepos: array with coefficient of friction for requested positions (same number) [[mue_0], [mue_1], [mue_2], ...]]
