Publication number: 20230050144Abstract: A control device of an electric power steering device includes an arithmetic processing device having a comparison unit, a failure diagnosis unit, and a drive control unit. The comparison unit compares a difference between a first output signal output from a first sensor and a second output signal output from a second sensor with a first threshold value to determine a magnitude relationship, and compares a difference between the first output signal and a third output signal output from a third sensor with a second threshold value to determine a magnitude relationship. Based on a result of the comparison unit, the failure diagnosis unit identifies one abnormal sensor among the first, second and third sensor. Using output values from two normal sensors that are not identified as abnormal sensors among the first, second and third sensor, the drive control unit generates a drive control signal for driving an electric motor.Type: ApplicationFiled: February 3, 2021Publication date: February 16, 2023Applicant: HITACHI ASTEMO, LTD.Inventors: Keita YASU, Kazuya YAMANO, Atsushi MATSUOKA, Makoto GOTO

Patent number: 10899381Abstract: A steering device is provided to perform a safe transition from an automatic driving mode to a manual driving mode when necessary. When it is determined necessary to transition from the automatic driving mode to the manual driving mode during the automatic driving mode, a transition period before an end time point of the automatic driving mode is set, a driving operation reliability indicative of whether or not it is possible to perform the transition is determined, and the transition when it is determined that it is possible to perform the transition to the manual driving mode during the automatic driving mode. Consequently, the transition can be controlled so that transition is not performed instantly, such as, for example, in a case where a driver is not driving during the automatic driving mode and is not accustomed to manual driving.Type: GrantFiled: March 22, 2017Date of Patent: January 26, 2021Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Takahiro Itou, Kazuya Yamano, Yasuhito Nakakuki
