Patent number: 11975775Abstract: A steering control device for reducing a steering load on the driver by adjusting a gain of a rear wheel steering angle with respect to a front wheel steering angle operated by the driver according to a relative relationship between the vehicle and the parking frame to enable fine steering of the own vehicle near the parking frame when the four-wheel steering vehicle is parked. The steering control device is configured to control a rear wheel steering angle by a rear wheel steering system based on a front wheel steering angle operated by a driver, and includes an arithmetic device configured to reduce an absolute value of a gain of the rear wheel steering angle with respect to the front wheel steering angle as a positional relationship between an own vehicle and a parking frame comes closer when an own vehicle shifts to a parking driving mode.Type: GrantFiled: August 22, 2019Date of Patent: May 7, 2024Assignee: HITACHI ASTEMO, LTD.Inventors: Go Sakayori, Hiroshi Nakano, Yoshiji Hasegawa, Tomoaki Fujibayashi, Junya Takahashi

Publication number: 20240053766Abstract: The problem of ensuring safety and work efficiency for the actions of a control target is addressed in an environment in which different types of control systems coexist. A safety control server controls the actions of respective control targets in differing systems and includes an action adjustment unit that, for each control target of differing control systems, outputs to a control target an action adjustment instruction for adjusting the action of that control target when a contention occurs in which the action of that control target deviates from an assumed control result. An action plan adjustment unit, when the adjustment of the action satisfies a prescribed condition, adjusts an action plan indicating an action rule for achieving a function and avoiding a contention in a control target; and a safety rule adjustment unit adjusts a safety rule indicating an action rule for avoiding a contention in the control target.Type: ApplicationFiled: November 2, 2021Publication date: February 15, 2024Inventors: Nobuyasu KANEKAWA, Junya TAKAHASHI, Satoshi OTSUKA, Hiroyuki YAMADA
