US 2001/0054519 A1 · Automotive vehicle steering control device

Abstract

No automatic steering system is currently available, which has a drive device commonly used with a power steering device and which does not hinder the emergency escaping operation conducted by a driver. An image sensor for detecting a positional relationship between a subject automotive vehicle and an automotive vehicle lane, a target steering quantity calculating process for obtaining a target steering quantity A required for the automotive vehicle to run along the automotive vehicle lane based on the positional relationship, a torque sensor for detecting a manual steering force with which a driver operates a steering handle, a target steering quantity changing process for outputting a target steering quantity B by changing the target steering quantity A based on the manual steering force thus detected, a steering angle sensor for detecting an actual steering quantity, and an automatic steering force calculating process for obtaining an automatic steering force required to make the target steering quantity B and the actual steering quantity coincident with each other are provided. Even during the automatic steering, steering can be carried out based on the driver's intention.
