Patent number: 11702033Abstract: A vehicle operation detection device includes sensors laid out in a vehicle along an axis in an opening-closing direction of a door of the vehicle. When the user moves a part of a body toward the sensors and a motion of moving the part of the body along the axis is detected, the sensors detect an opening-closing operation for the door. The vehicle operation detection device further includes light-emitting members laid out in the vehicle along the axis in the opening-closing direction and an operation direction indicator configured to drive the light-emitting members in sequence in a first direction in a fully-closed state of the door and drives the light-emitting members in sequence in a second direction in a fully-open state of the door.Type: GrantFiled: March 3, 2020Date of Patent: July 18, 2023Assignees: AISIN CORPORATION, HONDA MOTOR CO., LTD.Inventors: Ayaka Shimizu, Takaya Aiyama, Koichi Hirota, Hiroshi Shingu, Kenichiro Kagawa, Toshihiro Kaneda, Makoto Ono, Satoshi Katayama

Publication number: 20230058461Abstract: A control device sets a second electricity control switch in an intermediate state in a process of switching a discharge battery for supplying a drive unit with an electrical current from a first battery to a second battery. Subsequently, when a comparative relationship between an electric potential of a smoothing capacitor and an electric potential of the second battery fulfills an intermediate state termination condition, the control device sets the second electricity control switch in a bidirectional conduction state. The intermediate state is when an electrical current flowing from the second battery to the drive unit is allowed, and an electrical current flowing from the drive unit to the second battery is inhibited. The bidirectional conduction state is when both of the electrical current flowing from the second battery to the drive unit and the electrical current flowing from the drive unit to the second battery are allowed.Type: ApplicationFiled: August 22, 2022Publication date: February 23, 2023Inventors: Masanori NEGORO, Katsuro SHIBAHARA, Satoshi KATAYAMA
