Change of Braking Behavior Related to the Difference of Control Algorithm of Collision-prevention Braking System

This study examines the collision-prevention support braking system and discusses a methodology for estimating the collision mitigation ratio using this system. A method for analyzing the collision-mitigation ratio is developed through a time series Monte-Carlo simulation based on the integrated error of driver and system. Driver performance, in terms of braking timing and deceleration level for collision avoidance, is analyzed in a driving simulator when the control timing of the braking-support system was changed. In this analysis, the braking behavior of driver during malfunction of the system and this behavior when the driver is informed about the malfunction are investigated. A driver model simulating braking operation, when a preceding vehicle started slowdown, is also constructed. Through time series Monte-Carlo simulations using this driver model, the frequency of collisions with a preceding vehicle and the collision velocity are estimated.
