Abstract: When a vehicle deviates from a guide route at a first branch point, the state of the first branch point is memorized. Afterward, when a second branch point becomes a target for a route guide and the state of the second branch point is similar to the memorized state, a user of the vehicle is provided with a guide for preventing deviation from the guide route at the second branch point with a manner of the guide changed. This procedure allows learning of tendency of the user with respect to a state apt to cause the user to mistake a guide route. A guide to help prevent a user from deviating from a guide route at a branch point can be thus performed appropriately.

Abstract: A pump apparatus comprises a piston, which is provided displaceably along a first chamber formed in a body under the action of a pilot pressure, an indirect medium composed of a non-compressive fluid and which is to be pressed by the piston, and a diaphragm that is flexibly bendable in cooperation with the indirect medium. When the fluid is discharged from a discharge port, a change in volume caused by the displacement of the piston in the axial direction is identical to the change in volume caused by the displacement of the diaphragm in the axial direction.

Abstract: A vehicle navigation system includes a computer-based control unit with a display unit. A group of regions or spots on a given map are designated beforehand as on-map targets. A judgement is made as to whether a predetermined condition for each on-map target, having been set beforehand, is fulfilled or not based on vehicle traveling conditions. The result of judgement is memorized. A user is informed directly or indirectly of the present status as to fulfillment/nonfulfillment of the predetermined condition for each on-map target based on the judgement information.

Abstract: In a navigation device, matching is executed between road shape data read from a map data storage medium and road shape data included in guidance route data received from a server. Road data relevant to that of the guidance route data is thereby designated from the road data stored in the map data storage medium. Connection relation of the road data between the map data storage medium and the guidance route is then established. This results in eliminating a problem that it is difficult for the navigation device to indicate a correct present position when the navigation device moves along a route different from the guidance route.
