SIMULATION SYSTEM FOR VEHICLE

A control operation representer of a simulation system for a vehicle represents control operation of a travel controller in accordance with vehicle external detection information outputted by a vehicle external detection controller based on a captured vehicle external image. A vehicle behavior calculator calculates behavior of the vehicle in accordance with the control operation. A vehicle external image generator generates a vehicle external image in accordance with the behavior and displays the vehicle external image on a display member. An imaging member captures the vehicle external image displayed, and outputs a captured vehicle external image to the vehicle external detection controller. The vehicle external detection controller operates in a closed loop including these. The travel controller operates, outside the closed loop, in accordance with information generated by the vehicle external detection controller or information equivalent to the information generated by the vehicle external detection controller.
