Vehicle Models Integration Function

Hi. I repeatedly get problems with scipy odeint and the vehicle model functions provided by commonroad. The state and control values seem reasonable though.
E.g.: ODEintWarning: Excess work done on this call (perhaps wrong Dfun type). Run with full_output = 1 to get quantitative information. warnings.warn(warning_msg, ODEintWarning)

Hi Rudolf,

thanks for your post. Could you provide some more details, i.e., which vehicle model or which exemplary inputs/initial states caused this error?

Best,
Gerald

Hi there. Models with high nonlinearities, which are the MB and the dynamic ST model in my case for vehicle parameters 2 and 1. It happens occasionally during simulation. I did not observe pattern, e.g., it is not only relate to highly dynamic driving.
