Abstract
This paper discusses an analysis of "driver-vehicle" behavior at braking in turning. In this study, a new braking model has been developed in consideration of actual driver's operation, and experiments were conducted on mountain roads to identify one novice and skilled driver's braking model parameters. The computer simulations have shown the following tendency. The novice driver needed more compensatory steering operation than the skilled driver to trace the course. A controlled braking force distribution have been particularly effective for the novice driver.
