toRoadCoordinates()

RoadCoordinates adore::fun::RoadCoordinateConverter::toRoadCoordinates ( const PlanarVehicleState10d &  x, bool  log = false  )

Compute road coordinates from vehicle state.

Parameters

x	vehicle state in Euclidean coordinates

Returns

state in road-relative coordinates

toVehicleState()

void adore::fun::RoadCoordinateConverter::toVehicleState ( const RoadCoordinates &  r, double  psi, double  omega, PlanarVehicleState10d &  x, bool  log = false  )

inline

Compute vehicle state from road coordiantes The zero dynamic state has to be provided in order to allow the euqation to be solved. In this method, the zero dynamic state is represented by z=[psi,omega=d psi/dt]

Parameters

r	the vehicle state in road-relative coordinates
psi	the yaw angle of the vehicle, when arriving at r
omega	the yaw rate of the vehicle, when arriving at r
x	the resulting full vehicle state with position in Euclidean cordinates. Returned by function.

toVehicleStateTrajectory()

adoreMatrix<double,0,0> adore::fun::RoadCoordinateConverter::toVehicleStateTrajectory ( adore::mad::AScalarToN< double, 4 > *  lon_trajectory_rc, adore::mad::AScalarToN< double, 4 > *  lat_trajectory_rc, const adoreMatrix< double, 1, 0 > &  integration_time, double  s0, double  psi0, double  omega0  )

inline

Converts a decoupled plan in road coordinates into a 10d vehicle state trajectory. The zero dynamics are initialized with psi0 and omega0 (expected states at the beginning of the plan).

Parameters

lon_trajectory_rc	the longitudinal plan
lat_trajectory_rc	the lateral plan
integration_time	the time parametrization of the resulting trajectory, also time steps of integration
s0	progress offset to be used if longitudinal plan starts at 0
psi0	initial heading of vehicle
omega0	initial yaw rate of vehicle
