A Study on an Acceleration/deceleration Model based on Time Variation of Road Curvature Ahead of a Running Vehicle: A Pre-corner-entry Deceleration Model based on G-vectoring

摘要

A new deceleration model based on a G-vectoring concept-which predicts deceleration of a vehicle before itrnenters a curve-was developed. In this model, the predicted lateral jerk, which acts on the vehicle during cornering, is usedrnto decelerate the vehicle. The curvature of the road ahead is used to predict the lateral jerk according to the time variation ofrnroad curvature. It is confirmed that the deceleration calculated by this model can imitate the deceleration caused by therndriver’s braking. This model will be useful for improving the driver’s feeling of deceleration that an auto-brake controlrnsystem creates before the vehicle enters a curve.
