Embodiment Construction

[0015] Before explaining any embodiment of the present invention in detail, it should be understood that the application of the present invention is not limited to the specific construction and arrangement of elements shown in the following description or drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.

[0016] figure 1 A vehicle 10 is shown. Vehicle 10 includes an object detection controller 12 . Object detection controller 12 is connected to a network such as a controller area network (“CAN”) bus 16 . Bus 16 allows controller 12 to exchange data with other devices connected to bus 16 , such as one or more environmental sensors 22 . Although the bus 16 is shown connecting various components in the vehicle 10 , other connections between components, whether wired or wireless, directly or indirectly, are possible.

[0017] Environmental sensors 22 have one or more radar, sonar, ultrasonic and / or optical sensors ...

Abstract

A system and method for detecting a vehicle. A system includes a controller. The controller is configured to: receive data from at least one camera mounted on the first vehicle; identify a surface of a second vehicle located around the first vehicle based on the images; and generate a three-dimensional model associated with the second vehicle. The model includes a first plane and a second plane approximately perpendicular to the first plane. The first plane of the model is associated with the identified surface of the second vehicle. The controller is still further configured to use the three-dimensional model to track the position of the second vehicle after the identified surface falls at least partially outside the field of view of the at least one camera.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application 61 / 615,596, filed March 26, 2012, which is hereby incorporated by reference in its entirety. Background technique [0003] The existing Adaptive Cruise Control (“ACC”) and Forward Collision Warning (“FCW”) provide a radar sensor solution with the optional addition of a forward-looking black and white camera. Radar sensors work well for longitudinal spacing and speed measurements, but cannot detect certain traffic situations that depend on accurate and robust lateral tracking. For example, existing radar systems often fail to detect adjacent lane interference that occurs when one vehicle overtakes another, such as a relatively slow-speed semi-truck. In particular, due to the large volume on one side of the truck, the radar system may encounter scattered reflections from adjacent lanes and be unable to continue tracking of previously seen vehicles. Existing radar systems a...
