Patent number: 11975758Abstract: A first risk potential field for a risk avoidance control is a sum of a risk potential field in which a valley of a risk value extends in a lane longitudinal direction and a risk potential field in which the risk value is maximum at a position of an object and decreases as a distance from the object increases. The steering control is executed such that a vehicle approaches a first minimum point that is a minimum point of the first risk potential field and that is searched for in a first search range. When a plurality of first minimum point candidates is present in the first search range, the first minimum point candidate that is present in a direction away from a foremost object as viewed from a previous minimum point and is the closest to the previous minimum point is selected as the current first minimum point.Type: GrantFiled: September 13, 2021Date of Patent: May 7, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Toshiki Kinoshita

Patent number: 11897561Abstract: A driving system for automated driving includes at least automated lateral guidance for a motor vehicle. The system is configured to determine whether one or more indications of a current or imminent manual steering intervention are present, which do not take place inadvertently and are intentional by a driver.
