  • Patent number: 8364366
    Abstract: A sensing system collects position data associated with one or more obstacles within a certain range of a vehicle. A former establishes an occupancy grid based on the collected position data. A motion monitoring module determines a reaction distance and a deceleration distance associated with a vehicle at a regular time interval during an operational state. A safety guidance module establishes a safety zone (e.g., safety zone grid) for the regular time interval based on the occupancy grid, the determined reaction distance, and the deceleration distance.

  • Patent number: 8060306
    Abstract: A mapping module or path filtering module is arranged to identify admissible curved paths for which the vehicle is able to stop prior to reaching a detected obstacle in accordance with an observed translational velocity and an observed rotational velocity. A data processor determines a respective objective function for the candidate translational velocities and candidate rotational velocities associated with the admissible curved paths, where the objective function includes a curvature comparison term associated with the last curved path of the vehicle. A search engine or data processor selects preferential velocities, among the candidate translational velocities and candidate rotational velocities, with a superior value for its corresponding objective function. A path planning module or data processor determines the vehicular speed and trajectory for a path plan that avoids the obstacle consistent with the selected preferential velocities.

  • Patent number: 7164118
    Abstract: A method and system for detecting the presence of an object or the distance between the system and an object supports the provision of rapid and reliable obstacle detection. A transmitter emits generally linear beams of electromagnetic radiation with a transmitted radiation pattern within a defined spatial zone. A camera collects an image of the defined spatial zone. A data processor detects a presence of an object in the collected image based on an observed illumination radiation pattern on an object formed by at least one of the generally linear beams. A distance estimator estimates a distance between the object and the optical device based on a change (e.g., an observed shift in one or more positions of generally linear beams) from the transmitted radiation pattern to the observed illumination radiation pattern.
