GPS/IMU/Video/Radar absolute/relative positioning communication/computation sensor platform for automotive safety applications
First Claim
1. ) The architecture of a device platform specifically designed for automotive safety applications. The device platform architecture consists of a central data fusing processor, with communication paths to Vehicle-2-Vehicle (V2V) communication cards, to Vehicle-2-Infrastructure communication cards, to the host vehicle controls, to a GNSS signal tracking and acquisition device, to an Inertial Measurement Unit (IMU) sensor, to accelerometers distributed along the body of the host vehicle, to radars, to video cameras and to any other sensors installed in the host vehicle which can provide data able to enhance the host vehicle position and orientation estimation (e.g. compasses, inclinometers, etc.).

Abstract
A GPS/IMU safety sensor platform is proposed, consisting of data fusion Processors, GNSS Signal Acquisition and Tracking Processors, MEMS IMU sensors, one or multiple accelerometers able to provide orientation information, optional V2V communication modules, and optional V2I communication modules. The data fusion processors provide interface ports to GNSS/IMU processors, odometers, video (Visual/Infrared) cameras installed in the vehicle, V2V relative positioning sensors (laser, radar or any other distance measuring), and V2V and V2I communication modules. The data fusion processors are interfaced to a driver warning system and optionally to the vehicle controls for providing safety warning messages to drivers, or for automatic control the vehicle for preventing and reducing accidents.
