A Slalom event drives the vehicle in a straight, followed by a sequence of turns around
cones in alternate directions. The vehicle velocity is held constant.
Output Requests are included to measure the vehicle state
variables, tire forces, and tire state variables. The Altair Driver steers the vehicle and
maintains constant speed. A plot template is available to plot the results.
This test is
used to measure the dynamic response of the vehicle while traversing the path around cones.

The parameters available in the Slalom event are detailed in the following
table:
Parameter
Description
Units
Length unit selection (Model, m, ft).
Velocity unit selection (Model, m/s,
km/h, mph).
Initial straight
Vehicle is driven straight this distance before starting in the turn
sequence.
Cone spacing
Distance between cones placed longitudinally with respect to vehicle.
Lateral displacement
Lateral distance of the vehicle desired path from the cones.
Final straight
Straight distance section of the path after the turn sequence.
Number of cones
Number of cones placed in the path.
Velocity
Desired speed of the vehicle.
Turn direction
Direction the vehicle turns during the event (as seen by the driver).
Look ahead time
Look ahead time Look ahead time, used by the Driver feedforward steering
model.
Prediction step size
Maximum step size, used by Driver feedforward steering model.
