GNSS/IMU positioning, communication, and computation platforms for automotive safety applications
First Claim
1. An automotive safety system comprising:
- a central data fusing processor;
a global navigation satellite system (GNSS) signal tracking and acquisition device on a host vehicle;
an Inertial Measurement Unit (IMU) sensor on the host vehicle; and
a GNSS/IMU integration processor on the host vehicle configured to receive data from the GNSS signal tracking and acquisition device and the (IMU) sensor and transmit integrated data to the central data fusing processor.

Abstract
A GNSS/IMU safety sensor platform is disclosed consisting of data fusion Processors, GNSS 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 of the vehicle for preventing and reducing accidents.
