Hello! I am trying to simulate a vehicle model based on simscape but I am getting error while trying to increase the simulation time.

That is : ['vehicle_simple/Solver Configuration']: At time 10.133776, one or more assertions are triggered. See causes for specific information.

Rotational velocity must be less than or equal to Maximum speed. The assertion comes from:

Block path: vehicle_simple/Generic Engine

Assert location:

o (location information is protected)

Kindly guide me through this.

Thank You

The Generic Engine model is defined by a torque-speed lookup table. If the conditions in your simulation exceed the maximum speed, your model is no longer valid. Make sure the conditions in your model are physically realistic, and you can also enable the Redline control setting.

Hello Sir.

I am going through same problem in simulation. Which Condition you are talking about to exceed the maximum speed. I have used a Indian driving cycle as input to the simulation which having maximum speed 55km/hrs.

Kimdly guide me sir

Thank You
