Abstract: An apparatus for facilitating avoidance of a vehicle collision with an object, comprises a vision sensor providing image data, and an image analyzer, operable to provide an estimated time to collision of the vehicle with the object. The estimated time to collision is determined from a rate of expansion of an image element corresponding to the object within the image data, and the apparatus provides a warning if the estimated time to collision is less than or approximately equal to a predetermined time.

Abstract: When a vehicle is moving out of a lane of a road, an image processing computer unit judges the hazardous condition. Then, a power steering control computer unit calculates a correction reaction force based on the steering angular velocity and increases a steering reaction force so as to generate a large steering effort. This lane moving-out prevention system is constituted such that only when the steering angular velocity is large, i.e., when a driver turns a steering wheel sharply, the steering reaction force is increased, thereby no additional reaction force is produced when the driver makes a normal turn.

Abstract: A system for detecting hazardous conditions during operation of a vehicle. In one embodiment, the system includes a plurality of sensors that monitor a plurality of conditions and transmit condition signals each representing a measure of a condition. A plurality of rate determination circuits is coupled to the sensors and continually receives the condition signals, wherein each rate determination circuit calculates rates of change for the condition, including a baseline rate of change, and outputs a potential hazard value representing a deviation of a rate of change from the baseline rate that exceeds a predetermined threshold value. An evaluation circuit receives the potential hazard value, calculates a new potential hazard value using the potential hazard value and a rate of change for at least one associated condition and determines whether an actual hazard exists by comparing the new potential hazard value with a stored value that corresponds to the condition.

Abstract: A system for determining the location of an object includes an interrogator remote from the object and a transponder located at the object. The interrogator receives GPS signals and transmits pre-positioning data and a tracking signal to the transponder. The pre-positioning data includes pseudorandom noise (PRN) code number, Doppler frequency offset and code phase offset while the tracking signal includes reference time and frequency information. The transponder collects RF samples of at least one of the GPS signals associated with one of the PRN code numbers and correlates the RF samples of the GPS signal against code replicas of the GPS signal based on the Doppler frequency offset, code phase offset and reference time and frequency information for that GPS signal to produce the correlation snapshot. The transponder transmits the correlation snapshot to the interrogator and the interrogator determines the pseudorange associated with the GPS signal using the correlation snapshot.

Abstract: An apparatus for analyzing a specified path A-B with respect to a specified obstacle determines if the path intersects the obstacle and determines a collision avoidance path when the path is determined to intersect the obstacle. The apparatus is preferably a dedicated path analyzer that provides high speed path analysis support to a host computer performing navigation functions. The path analyzer includes a collision detector and a collision avoidance path generator. The path analyzer receives from the host computer coordinates representing the specified path's first and second endpoints (A and B) in three dimensional space and the specified obstacle's physical extent. The collision detector generates a preliminary result signal indicating whether the specified path does not intercept the specified obstacle, unavoidably intercepts the specified obstacle, or avoidably intercepts the specified obstacle. When the preliminary result signal indicates that the specified path avoidably intercepts the specified obstacle, the collision avoidance path generator selecting a vertex (C) of a parallelepiped corresponding to the specified obstacle's physical extent, such that a modified path A-C-B from the first specified path endpoint to the selected vertex to the second specified path endpoint circumnavigates the obstacle. The path analyzer returns signals to the host computer representing the preliminary result signal and, when the preliminary result signal indicates that the specified path avoidably intercepts the specified obstacle, the selected vertex.
