Vehicle Simulation - Matlab Simulink

hi there, i am currently developing a vehicle simulation model using matlab simulink.
The simulation requires a vehicle to be simulated traveling around a simple race track. the vehicle model itself has already been created and have all necessary vehicle input data for the simulation.

Hi, I am dealing with a vehicle dynamics model ,The problem is, I am getting  !!!

Need Help In Modeling Longitudinal Vehicle Dynamics

Dear all I am a Master student in Vehicle dynamics and control from Paderborn. To have a basis for my research, i need to develop a longitudinal vehicle model for acceleration considering the tyre slip.
I have all the equations(for wheel dynamics,vehicle dynamics(Fx=m*a)and slip calculation)to develop a model .
