Abstract: A voice recognition operation system and a method for operating the same are disclosed wherein a verbal input is compared with a recognition word set stored in a memory 8 which stores correlated interactive operational patterns to select a pertinent recognition word set and interactive operational pattern, with the selected data being displayed over a speaker 5 and a display 3. A new mode recognition mode setting device 7 enables setting of a new registering mode in which an input section 1, 2, 7 enables inputting of various information into the memory 8, and a setting section 9 enables setting of a new recognition word set and an interactive operational pattern, to be used for new voice recognition operational purpose, on the basis of various information in the presence of the new registering mode. A registering section 9 registers the preset resultant data in the memory 8.

Abstract: An apparatus provides information for a driver and passengers in a vehicle. If it is estimated that driving load is high, the apparatus stops outputting information. If it is estimated that driving load has been changed from high to low, the apparatus reads information from a storage unit and outputs the read information. If it is estimated that driving load is high, the apparatus stops outputting information so that the driver and passengers may miss no information, and if it is estimated that driving load is low, the apparatus provides information for the driver and passengers so that they may surely catch the information.

Abstract: In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale.

Abstract: A map display apparatus for displaying perspective image of a map. The apparatus includes an image display device for displaying the perspective image of the map and a map data storage device for storing map data. Map drawing means is included for preparing map drawing data using the map data and for displaying a perspective image of the map on the display device on the basis of the drawing data. The map drawing means transforms coordinate data of a map into data suitable for display of the perspective image of the map. The data transformation is accomplished by perspectively projecting the coordinate data onto a predetermined projection plane with a view point at a desired position. The projection plane is determined on the basis of two predetermined points in the map data, such as the current position of a vehicle and the destination, so that drawing positions of the two points after the perspectively projecting operation are coincident with predetermined positions.

Abstract: Stereo image data depicting the lane on which the vehicle is running is rectified into a planar image on which one or more level lines can be generated in a manner to intersect one or both of the edges of the lane. Angles are measured between lines which extend from these the points if intersection in directions normal to the level line or lines and lines which extend tangentially to any curvature which occurs in the road edges at the point of intersection. These angles are recorded, the difference therebetween determined and compared in a manner which determines the attitude of the vehicle on the road. The curvature of the road and the vehicle speed are determined and the best steering angle for the road wheels determined in accordance With a schedule which is recorded in terms of attitude and a parameter variable with the vehicle speed and road curvature.

Abstract: An image processing section receives data from cameras mounted on the vehicle and produces an image or images from which a first set of so called "local" data is derived and compiled. A sensor section senses the rotational characteristics of two vehicle wheels and the conditions prevailing on either side of the vehicle and complies a second set of so called "global" data. The local and global data are compared and data is only accepted in the event that the differences between the two sets of data fall within predetermined limits and data which falls outside of the ranges deemed erroneous and rejected.

Abstract: A man-machine system and method for backing up layout of assembly parts for a vehicle in which any one of assembly part positions, e.g., a recovery limit position of a clutch pedal is specified to set a temporary layout of each assembly part such as the clutch pedal, a coordinate position of each element on the temporary layout such as the recovery limit position is calculated on the basis of a basic data on the temporary layout for the calculation under at least one set condition (rule), and a value of data having a positional relationship to another assembly part such as a height difference between the clutch pedal and a brake pedal is calculated under the set condition. After the system determines whether the calculated data value having the positional relationship to the other assembly part is within an allowable range, a system user determines whether the calculated coordinate position adopts the layout.

Abstract: A system for calculating a movement direction and position of a movable object such as an unmanned vehicle running within a factory and a method therefor are disclosed in which an image pick up camera such as a video camera photographs a background of the movable object to generate a background two-dimensional image. Positions of vanishing point and side ends of a passage on which the movable object is to move are derived from the background photographed two-dimensional image. The movement direction of the movable object is derived from the detected vanishing point. Distances of the movable object from both sides ends of the passage are derived on the basis of the detected vanishing point and positions of side ends of the passage. the movement direction and position of the movable object thus detected are used to control movement of the movable object. The vanishing point is detected on the basis of edge directions at all points constituting and edge on the background two-dimensional image.
