AUTOMATIC STEERING CONTROL DEVICE FOR VEHICLE AND AUTOMATIC STEERING CONTROL SYSTEM

摘要

The present invention comprises a steering force detection unit (5) which detects a steering force of an operation of a steering wheel (1) by a driver and a lateral deviation calculation unit (202) which detects a lateral deviation in a direction perpendicular to a travel direction of an own vehicle on a travel road, and an automatic steering control amount acting on the steering force is controlled according to the magnitude of the lateral deviation, on the basis of the steering force of the operation of the steering wheel by the driver detected by the steering force detection unit (5) and the lateral deviation in the direction perpendicular to the travel direction of the own vehicle on the travel road detected by the lateral deviation calculation unit (202), such that the automatic steering control amount acting on the steering force of the operation of the steering wheel by the driver is larger in a case in which the lateral deviation is larger than that in a case in which the lateral deviation is small, thereby appropriately carrying out control of the automatic steering or control of steering assist according to steering intention of the driver.
