Pressure regulating system for use in an automatic transmission including a fluid coupling, a belt drive continuously-variable speed transmission mechanism having an input pulley and an output pulley which are rotatably interlocked with a V-belt and a reduction ratio control system for controlling the reduction ratio of the belt drive continuously-variable speed transmission mechanism. The pressure regulating system includes a regulator valve capable of regulating the discharge pressure of an oil pump to provide a line pressure, a reduction ratio detecting valve and a throttle pressure valve. The reduction ratio detecting valve receives the line pressure and provides a pressure which is proportional to the displacement of the movable flange of the output pulley with respect to the corresponding fixed flange. The throttle pressure valve receives the line pressure and provides a first throttle pressure which is proportional to the degree of throttle opening of an internal-combustion engine and receives the reduction ratio pressure and provides the same reduction ratio pressure as a second throttle pressure only when the degree of throttle opening exceeds a predetermined value. The regulator valve receives the reduction ratio pressure, the first throttle pressure and the second throttle pressure to regulate the line pressure.

Disclosed is a communicatory navigation system including an information center (150), at least one navigation unit (100) each mounted on a vehicle and communication means for allowing bi-directional data communication between the information center and the navigation unit. Data transmission from the navigation unit to the information center is made during a period of communication that begins when the navigation unit become communicatable with the information center and ends when the bi-directional data communication therebetween is disconnected. The navigation unit is provided with a drive route history memory area (131) and an instrument operation history memory area (132), and data in these memory areas are transmitted to the information center, together with the vehicle current position data and the destination position data. The information center determines a recommended drive route from the current position to the destination, not only with reference to its own database (158) but also taking into consideration the history data. For example, if it is determined that there is a traffic accident or heavy traffic jam in some route, a bypass route is determined and transmitted back to the navigation unit. When the previous drive route indicated by data in area (131) is not found in the database (158), it can be recognized as a newly constructed road for inclusion in the database.

A route guidance section compares the current position provided by a current position determination section and the route provided by a route calculation section for detecting an off-route condition. When the off-route condition is detected, a researching key as well as the route and current place is displayed on a display section. When the researching key is touched, a search is again made for a new route from the current position to the destination. Then, route guidance is again started in response to the researching result. When the researching key is not touched, the route and current place continue to be displayed while the vehicle carrying the apparatus travles off route, thereby efficiently preventing the apparatus from executing unnecessary researching when the driver drives the vehicle off route on purpose.

An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.
摘要:
In a navigation apparatus for setting a route from a designated departure point to a destination and providing guidance along the route, there are provided, as map data used in route exploration, node data [FIG. 15(b)] comprising position information and information relating to the attributes thereof, intersection data [FIGS. 2-5(b), FIG. 15(b)] comprising information relating to intersections, and road data [FIGS. 2-5(a), FIG. 15(c)] comprising information related to roads. Information such as roads between intersections and intersections which are the starting and end points of roads are obtained from the intersection data and road data, and an optimum route is retrieved by comparing routes. The map data is put into the form of a layered structure, as shown in FIG. 1, a branch road network is developed in an upper-layer (2) connected to a trunk road network with respect to a higher-order layer (1) of the trunk road network, block division is performed, and exploration from a lower-order layer to intersections connected to a road network of the higher-order layer is successively repeated. The foregoing makes it possible to perform processing upon limiting the range of exploration, and to raise the speed of exploration processing. In addition, the work area needed for exploration can be reduced and storage data can be conserved.
