Patent number: 10576972Abstract: A host vehicle has an automatic brake control that is executed for avoiding contact between the host vehicle and a pedestrian upon detecting a pedestrian is present in a forward position of the host vehicle using a front camera and a radar. In a driving assist control method, upon detecting an object in front of the host vehicle to be a pedestrian candidate based on an image signal from the front camera, execution of an automatic brake control is permitted with the detected pedestrian candidate as the control target. Thereafter, whether or not the pedestrian candidate detected by the front camera matches an object detected by the reflected waves from the millimeter wave radar is determined by comparison. Execution of the automatic brake control is continued or stopped based on the result of the comparison determination.Type: GrantFiled: November 28, 2016Date of Patent: March 3, 2020Assignee: Nissan Motor Co., Ltd.Inventors: Toshimichi Gokan, Takuya Inoue, Tatsuya Suzuki, Kazuo Tamaki

Patent number: 10503985Abstract: A host vehicle is provided with external environment recognition sensors that acquire forward information to determine that a pedestrian is present in a forward position of the host vehicle using the external environment recognition sensors. In this pedestrian determination method, a front camera and a millimeter wave radar are provided as the external environment recognition sensors. When a pedestrian candidate is detected in a forward position of the host vehicle based on an image signal from the front camera, a matching area is set with the position of the detected pedestrian candidate as the center point. When the position of the object that is closest to the pedestrian candidate from among the plurality of objects detected by reflected waves from the millimeter wave radar is within the matching area thereby establishing a match, the pedestrian candidate is determined to be a pedestrian.Type: GrantFiled: November 28, 2016Date of Patent: December 10, 2019Assignee: Nissan Motor Co., Ltd.Inventors: Toshimichi Gokan, Takuya Inoue, Tatsuya Suzuki, Kazuo Tamaki
