1. An automotive safety system comprising:

  • a central data fusing processor;

    a Vehicle-2-Vehicle (V2V) communication module;

    a Vehicle-2-Infrastructure (V2I) communication module;

    vehicle controls on a host vehicle;

    a GNSS signal tracking and acquisition device;

    an Inertial Measurement Unit (IMU) sensor; and

    a GNSS/IMU integration processor configured to receive data from the GNSS signal tracking and acquisition device and the Inertial Measurement Unit (IMU) sensor and transmit integrated data to the central data fusing processor;

    wherein the host vehicle and at least one other vehicle is part of a network and the central data fusing processor is configured to optimally combine at least two of other vehicle Inertial Measurement Unit (IMU) measurements, other vehicle radar measurements, other vehicle image measurements, other vehicle compass measurements, other vehicle inclinometer measurements, and other vehicle sensor measurements are to compute relative position and relative orientation of the host vehicle with respect to other vehicles in the network.
