Throttle-off Cornering
A Throttle-off cornering event simulates the dynamics of a vehicle driving a constant radius turn at steady state and the reaction of the vehicle due to a sudden removal of the drive torque while cornering.
The event includes a short straight section to allow the vehicle to come to steady state, the constant radius circle, throttle removal, and the subsequent vehicle reaction. A left or right turn can be simulated. The appropriate vehicle and tire output requests are included. A plot template is available to plot the results.
Parameter | Description |
---|---|
Radius | The radius of the circle that the vehicle CG will follow during the constant radius portion of the event. |
Initial straight | Length of the initial straight road section in meters. This section is used to allow the vehicle to reach steady state. |
Turn direction | Direction the vehicle turns during the event (as seen by the driver). |
Velocity | Velocity of the vehicle in meters/sec. |
Look ahead time | Look ahead time used by the Altair Driver model. |
Prediction step size | Maximum step size used by MotionSolve integrator. |
Throttle off time | The absolute time in the simulation that the Altair Driver begins removing drive torque. |
Throttle step duration | The length of the time the throttle controller takes to completely remove the drive torque. |
End time | Absolute end time of the event, in seconds. |
Print interval | Data is output to the plot files and graphics file at this time interval (seconds). |
