1. a front vehicle collision risk monitoring device is characterized in that, comprising:

  • Two wheel speed sensors are installed in respectively on left back wheel of vehicle and the right rear wheel, are used for the rotating speed of left back wheel of measuring vehicle and right rear wheel;

    An inertia sensor is installed in the vehicle centroid position, measures the yaw velocity of vehicle;

    A laser scanner is installed in the middle of the vehicle rear bumper arm backward, measures relative distance, relative angle and the relative velocity of other vehicles of rear and vehicle;

    A microprocessor, be installed in operator'"'"'s compartment, be electrically connected two wheel speed sensors, inertia sensor and laser scanner respectively, receive the data that wheel speed sensor, inertia sensor and laser scanner are exported, by the radius of curvature of data computation vehicle driving trace;

    Then, based on the radius of curvature of vehicle driving trace and relative distance, the relative angle of other vehicles of rear and vehicle, judge the relative position relation of front vehicle and vehicle;

    At last, make collision risk according to relative velocity and judge output alarm information.
