Hello, Can you give me some advice about my results of comparison. I wanted to compare double lane change with some maneuver as open loop. I did it this way: I have created Double lane change simulation. In PPT i saved data from all demands (vas_steering_demand_data,_vas_throttle_demand_data,...) Made open loop dcd file From event generated during standard DLC, i changed every input to open, and attached my dcd file Made file driven simulation Some results are perfectly same: The biggest difference are in results in accelerations i.e.: and in this Is this caused with different longitudinal velocities of vehicle (open loop model is going faster, mdi driver in closed loop is correcting velocity ???) or i am wrong with my assumption. How to make this comparison better and more precise? Thanks a lot Jozef

Comparison of DLC as open and closed loop event

Hello,

Can you give me some advice about my results of comparison. I wanted to compare double lane change with some maneuver as open loop. I did it this way:

I have created Double lane change simulation.
In PPT i saved data from all demands (vas_steering_demand_data,_vas_throttle_demand_data,...)
Made open loop dcd file
From event generated during standard DLC, i changed every input to open, and attached my dcd file
Made file driven simulation

Some results are perfectly same:

The biggest difference are in results in accelerations i.e.:

and in this

Is this caused with different longitudinal velocities of vehicle (open loop model is going faster, mdi driver in closed loop is correcting velocity ???)

or i am wrong with my assumption.

How to make this comparison better and more precise?

Thanks a lot

Have you tried to tighten error and hmax?

There can also be some of the magic applied in the initialization/ static setup that affects the whole history.
