EV Vehicle Transmission Modelling


I am attempting to model an initial EV design in carmaker. The design is base don a 1 motor system and automatic gearbox. When I select automatic under Drive Source > Gearbox, the clutch parameters become unavailable as expected. However when trying to run the simulation an error arises indicating that the clutch properties are not specified.

The simulation will only run when ‘Automated Manual Transmission’ is selected, but this is not fully representative of the design we have.

Please can you advise on how to simulate the EV vehicle with an automatic gearbox and no clutch?

Thank you
