Patent number: 9177478Abstract: A vehicle contact avoidance system includes a detection system, a warning system, and a controller. The detection system is configured to detect a remote obstacle in proximity to a host vehicle equipped with the vehicle contact avoidance system, including information related to at least one of a speed, a direction and a distance of the remote obstacle relative to the host vehicle. The warning system is configured to emit a warning sound to notify a driver of the host vehicle of imminent contact between the host vehicle and the remote obstacle. The controller is programmed to determine whether contact between the host vehicle and the remote obstacle is imminent based of the information supplied to the controller by the detection system, and programmed to cause the warning system to emit the warning sound. The warning sound includes a non-speech portion and a speech portion.Type: GrantFiled: November 1, 2013Date of Patent: November 3, 2015Assignee: NISSAN NORTH AMERICA, INC.Inventors: Heather Konet, Neal Probert, Jeremy Chambers, Roy Goudy, Andrew Christensen

Patent number: 9153132Abstract: An on-board vehicle control system and method employ a storage device that stores information representing a plurality of boundary points of a boundary circumscribing an area of interest in which the boundary points are defined by two prescribed parameters, and a controller that obtains at least one condition point defined by current values of the prescribed parameters, determines a first boundary point of the boundary points that is closest to the condition point, and generates geometric data representing a geometric relationship between the first boundary point, the condition point and a second boundary point of the boundary points. The controller performs further calculations taking into account the geometric data to generate coordinate condition data, and determines whether a warning condition exists by determining whether the condition point lies within the area of interest based on a comparison between coordinates of the condition point and the coordinate condition data.Type: GrantFiled: March 4, 2014Date of Patent: October 6, 2015Assignee: NISSAN NORTH AMERICA, INC.Inventors: Roy W Goudy, Neal Probert, Andrew Christensen, Jeremy S Chambers
