Publication number: 20230324545Abstract: An object detection device includes: a position detection unit configured to detect a position of an object outside a vehicle based on sensor information obtained at a predetermined cycle by an object detection sensor mounted on the vehicle; and a determination unit configured to determine whether the object is a moving object based on a time-series amount of change in the position of the object detected by the position detection unit. A first threshold on a lower limit side and a second threshold on an upper limit side are set as thresholds for the amount of change in the position of the moving object. The determination unit determines that the object is a moving object when the amount of change in the position is larger than the first threshold and equal to or smaller than the second threshold.Type: ApplicationFiled: March 30, 2023Publication date: October 12, 2023Applicant: AISIN CORPORATIONInventors: Koji NAGASE, Hideaki HIROSE, Eiji ITAMI, Kenichi TAGUCHI

Patent number: 7212897Abstract: In order to provide a vehicle door controlling apparatus, which even when the vehicle starts to move while doors of the vehicle are in closed operation, performs insertion detection accurately without reducing the sensitivity of insertion detection. In the present invention, speed adjustment is performed by an applied voltage and a vehicle door is driven by a motor by voltage driving. The speed during the movement of the vehicle door is detected by Hall elements, and the door speed during the movement of the vehicle door is obtained from the detected signal. A controller having an insertion detection function controls the door speed to be the predetermined target door speed. In this case, the controller detects stoppage or driving of the vehicle, and when the state of the vehicle is in the driving state while the vehicle door is in closing operation, the voltage applied to the motor is increased compared to the stop state.Type: GrantFiled: April 21, 2004Date of Patent: May 1, 2007Assignee: Aisin Seiki Kabushiki KaishaInventors: Shintaro Suzuki, Tomoaki Imaizumi, Eiji Itami
