Document Type and Number:
Japanese Patent JP2017013636
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To inhibit an automatic steering-related control from becoming unstable.SOLUTION: An automatic steering device 1 comprises: an EPS microcomputer 50 exerting a motor control over a motor 21 of a steering mechanism 7 on the basis of various command values input per predetermined cycle; and an automatic steering microcomputer 30 switching a control line in response to a vehicle state determination condition. Furthermore, the automatic steering device 1 comprises a yaw rate sensor 27 detecting a vibration generated in the steering mechanism 7. If determining a direct advance state of a vehicle and generation of the vibration in the steering mechanism 7 during a position control, the automatic steering microcomputer 30 switches a control line to a control line for an electric current control so as to temporarily disconnect a position control unit 51.SELECTED DRAWING: Figure 3
