  • Patent number: 6035253
    Abstract: In a navigation apparatus for a vehicle, after the present position of a vehicle is obtained, a position on a map which corresponds to the present position of the vehicle is obtained. Subsequently, the heading direction of the vehicle is detected. When the vehicle is traveling on the left-hand lane, coordinate conversion is performed such that a present position mark is shifted leftward from the center of the road by 1/4 of the road width. This makes it possible to display a route while preventing the route from overlapping with the centerline of the road. In another navigation apparatus for a vehicle, a structure-profiled map on which a structure-representing shape and a road are drawn is displayed so as to provide road guidance, wherein a route is displayed on the structure-profiled map along a road which is displayed for guidance. The display of the route is performed such that the route is shifted from the center line of a road toward a lane on which the vehicle is traveling.

  • Patent number: 5995897
    Abstract: A method is provided for accurately controlling a vehicle having a mini tire mounted as the spare tire. A short-term correction coefficient and a long-term correction coefficient are computed periodically for the left and right wheels, and a probable lateral acceleration G is computed from the difference between the ratio of the short-term correction coefficient to the long-term correction coefficient for the left and right wheels. A revised probable lateral acceleration G' is computed using the value of the long-term correction coefficient fixed at the point at which the absolute value of the probable lateral acceleration G has exceeded a prescribed value and the most recent short-term correction coefficient, from which a decision is made as to the state of a turn. The most recent long-term correction coefficient is used to make a correction for a mounted mini tire.

  • Patent number: 5961564
    Abstract: A wheel slip control system employs a method of varying the detection and correction parameters it uses based on whether the wheel/axle combinations on a truck of a rail vehicle operate in the coupled or decoupled modes of operation. The control system executes programming code featuring detection and correction logic. The steps of the method include deriving both detection parameters optimized for each mode called coupled and decoupled detection parameters and correction parameters optimized for each mode called coupled and decoupled correction parameters. Another step involves monitoring the amount of dynamic braking applied to the wheel/axle combinations. Yet another step involves determining whether the amount of dynamic braking lies for a preset time period within a preset zone of operation for the dynamic braking of the wheel/axle combinations on the truck.

  • Patent number: 5928299
    Abstract: An azimuth change quantity .theta. of a road during traveling of a vehicle for a time .delta.t is calculated based on road data provided by a navigation system and a vehicle speed provided by a vehicle speed sensor (at step S3 in FIG. 2). On the other hand, an azimuth change quantity .THETA. of the vehicle is calculated by integrating a yaw rate .gamma. obtained from a yaw rate sensor over the time .delta.t (at step S5). A deviation D between the azimuth change quantity .theta. of the road and the azimuth change quantity .THETA. of the vehicle is calculated (at step S6). When the deviation D becomes equal to or larger than a reference value .beta., it is determined that there is a possibility that the vehicle will depart from the road (at step S9), and a predetermined steering torque is applied to a steering device, so that the deviation is converged into zero (at steps S10 and S11).
