Patent ID: 7421890

Claim:
A tire HIL simulator comprising: a tire testing apparatus which allows a real tire to come into contact with a mimic road surface body to conduct a running test of the tire; and a controller which has a vehicle model, and obtains measurement data from the tire testing apparatus as an input value and makes a predetermined calculation using the vehicle model, and outputs a command value based on a result of the calculation to an actuator of the tire testing apparatus, wherein the tire testing apparatus includes: a side force measuring device for measuring a tire side force applied to the tire; and actuators for imparting a contact load, a side-slip angle and a camber angle to the tire, respectively, and the controller obtains a steering angle and a tire side force from the side force measuring device as an input value, and calculates a three-dimensional motion of a vehicle using the vehicle model, and outputs command values as a contact load, a side-slip angle, and a camber angle to the respective actuators based on a result of the calculation.
