Publication number: 20180022382Abstract: A target steering angle calculator calculates, based on a target curvature, a target steering angle representing a steering angle of the vehicle at a target position. A current steering-angle obtainer obtains a current steering angle representing a steering angle of the vehicle at a current position. A steering controller controls the steering of the vehicle to cause the current steering angle to follow the target steering angle. A distance estimator estimates, based on at least one of the environmental information around the vehicle and control information about the vehicle, a visible distance representing a distance visibly recognizable by the driver of the vehicle to a front of the vehicle. The target curvature obtainer uses the visible distance as the target distance to obtain the target curvature at the predetermined target position that has the visible distance away from the current position along the road in the travelling direction.Type: ApplicationFiled: July 18, 2017Publication date: January 25, 2018Inventors: Hisaya AKATSUKA, Hiroshi INOU

Patent number: 8489252Abstract: In an obtainer for obtaining speed feeling of a driver of a movable object, a gaze point setter sets a gaze point of the driver, and a motion detector detects relative motion of an environmental field around the mobile object with respect to the mobile object. A divergent component calculator projects the relative motion of the environmental field in a coordinate system. The coordinate system is formed by modeling a retina sphere of the driver of the mobile object. The divergent calculator calculates each of divergent components of the projected relative motion of the environmental field radially expanding from the gaze point. A speed feeling calculator calculates speed feeling of the driver based on the divergent components of the projected relative motion of the environmental field radially expanding from the gaze point calculated by the divergent component calculator.Type: GrantFiled: August 22, 2011Date of Patent: July 16, 2013Assignee: Denso CorporationInventors: Hiroshi Inou, Mamoru Sawada, Seiji Totsuka

Patent number: 8280588Abstract: A travel support apparatus sets a travel locus of a vehicle based on a gaze point of a driver of the vehicle. By utilizing the gaze point, the travel locus is calculated and set for the travel control of the vehicle, especially for a curved portion of a road, in a matching manner that the calculated travel locus approximates the travel locus created by the steering operation of the driver. The above locus calculation scheme generates a natural travel locus because the driver of the vehicle usually gazes at an exit of the curved portion of the road when he/she steers the vehicle on the road. The natural travel locus calculated and set by the travel support apparatus prevents the driver from having discomfort and/or unsafe feeling while the travel of the vehicle is controlled by the apparatus.Type: GrantFiled: August 4, 2009Date of Patent: October 2, 2012Assignee: Denso CorporationInventors: Hiroshi Inou, Mamoru Sawada

Patent number: 8131443Abstract: An acceleration control system controls acceleration of a vehicle to match the driver's feeling. In this control, the vehicle is controlled so that acceleration remains constant at the initial stage and then a differentiated value of a square power of a vehicle speed remains constant. This control is based on the finding of a normal acceleration operation attained by a driver. A linear relation exists between the acceleration in the initial stage of acceleration and the differentiated value of the square power of the speed. Switching of control from the constant acceleration to the constant differentiated value of the square power of the speed is made at a change-over speed determined by the linear relation.Type: GrantFiled: June 24, 2008Date of Patent: March 6, 2012Assignee: Denso CorporationInventors: Hiroshi Inou, Minoru Okada, Seiji Totsuka
