Driver model and assistance function evaluation apparatus and method for vehicle dynamics control system in which driver model is equipped
First Claim
1. A driver model used to reproduce a travel along a set target course through a simulation, comprising:
- a calculating section that detects a deviation between a vehicular lateral displacement which would be developed in a case where the vehicle is advanced to a forward gaze point with a present vehicle posture maintained, the forward gaze point being a point of place separated from the vehicle by a predetermined forward gaze distance when the vehicle is present on the target course and a deviation of a yaw angle displacement and a target yaw angle and calculates a steering angle imposed on a vehicle model through a feedback control using a positional deviation quantity and a positional deviation gain and a yaw angle deviation quantity and a yaw angle deviation gain.

Abstract
In assistance function evaluation apparatus and method for a vehicle dynamics control system, the vehicle dynamics control system being an object to be evaluated, a simulator is provided to obtain a data base when the vehicle dynamics control system is operated, a vehicle model, a road surface environment model, and a driver model that calculates a steering angle imposed on the vehicle model to trace a target course are provided, the simulator comprises a driver intention quantity detecting section that detects an intention quantity of a vehicle driver to move the vehicle in a lateral direction and a system function detecting section that detects a function quantity of the vehicle dynamics control system and evaluates that the assistance function of the vehicle dynamics control system is in conformity to the driver when the system function quantity and the driver intention quantity are balanced without excess or deficiency.
