In an automotive industry where the vehicle development stages are becoming more complex and accurate, for the manufacturers it is even more important to be able to quickly compare the results of experimental tests performed on the road in different conditions, in particular at different asphalt and air temperatures. If robust simulation tools can compare the acquired data available and evaluate a balanced target of the measures needed, a significant amount of time can be saved. The goal of this master thesis is to study how the asphalt temperature influences the tire and the vehicle lateral dynamic performance, considering mainly the cornering stiffness of both axles and then the parameters of the ramp steering.
