A voice route-guidance system for vehicles which terminates its route-guidance when the vehicle arrives at the destination and even if the present position of the vehicle is measured with low accuracy. An approach judging unit judges that the vehicle approaches a point spaced apart from a destination by a predetermined distance. A guidance termination judging unit further judges whether or not there is a point in which the route-guidance should be carried out between the present vehicle position and the destination. From these judgments, the system judges that the vehicle approaches the point spaced apart from the destination by the predetermined distance and also that all the route-guidance has been terminated. Thus, a termination unit terminates the route-guidance.

A navigation system includes a first information storage device containing stored map data and a display unit for displaying a map by reading the map data. Provision is made for setting a point on the map displayed by the display unit and for inputting a telephone number. A second information storage device is provided for registering the input telephone number in correlation with the positional coordinates of the set point.

Navigation system

Geographical, guide or search information and route information are stored in storage sections. An arithmetic section provides a route researching function with preference for the traveling direction of a vehicle. A route-calculating section is provided for re-calculating the route, and a route guide control system is also provided, inclusive of a route deviation-detecting section. The re-calculating section calculates either the shortest route from the point of deviation to the previous route or a new route to the destination. In case of the search of the shortest route to the previous route, the shortest route from the present location to the previous route is searched giving preference to the traveling direction, e.g. avoidance of a U-turn, on the basis of the search information relating to the immediate vicinity of the present location, so that the route to rejoin the previous route can be quickly calculated. In case of search of a new route, the whole route from the present location to the destination is searched, again giving weight to the present traveling direction, on the basis of the search information relating to the area between the present location and the destination, to guide the driver along a new route completely different from the previous one.

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.

Volume control of aural guidance of vehicle route guidance apparatus

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.

A shifter with a manual speed selecting mechanism for a vehicular automatic transmission. The shifter includes a stationary member mounted on a vehicle body; a rocking retainer supported in a manner to rock on a first axis extending through and fixed by the stationary member, for transmitting motion of a shift lever to the automatic transmission. The shift lever is supported for rotation on the first axis and on a second axis, which is perpendicular to the first axis, and is brought into and out of engagement with the rocking retainer when rotated on the second axis. A switch is provided for detecting the position of the shift lever. A lock plate is supported on the rocking retainer for bringing the rocking retainer into and out of engagement with the stationary member when actuated by the rotation of the shift lever on the second axis.

Belt driven continuously variable transmission

An output shaft of a motor is connected to an operating shaft through a reduction device made up by a spur gear or a helical gear, which is a reversible power transmission to drive actuator mechanisms on a primary pulley and secondary pulley at the same time. A holding device such as an electromagnetic brake, and so on, is installed to maintain the output shaft of the motor when the motor is under non-operation.

Variable transmission

One of bolt section or a nut section on a ball screw devices, or nut sections (for example) are connected to gear sections axially movable, while the bolt sections are connected to a stationary element, so that relative rotation is given to the bolt section and the nut section to adjust movable sheaves. Between another of the bolt section or the nut section on the ball screw devices, or the bolt sections (for example) and the stationary element, adjustable retainers are installed without axial move being allowed, and holding apparatus to hold the retainers at required position is installed with the retainers. Due to the above, initial tension and position of the belt are adjusted and determined by varying the nut sections in axial direction for the bolt sections. It is possible to perform this adjustment after the assembly is completed.
