Description

DETAILED DESCRIPTION OF THE INVENTION The present invention employs a single-menu system using function keys for a key human-powered device in a course guidance device, particularly for a course guidance device having multiple control modes for course guidance of a moving object. The present invention relates to a key-powered device that simplifies switching control between a plurality of control modes and adapts the operation to the user's sense of operation.

Prior to the present application, the applicants of the present application proposed a course guidance device that displays the traveling trajectory of a moving object based on detection signals from a direction sensor and a speed sensor mounted on the moving object and guides the driving course. It is carried out. In addition to the above-mentioned driving trajectory display function, the course guidance system rdt has a map display function, for example, a map search function to select a desired map from a large number of maps recorded on microfilm;
A planned driving course input function, a guidance function performed when the mobile object approaches a predetermined point, a planned course correction function to change the planned course set by the planned driving course function, and the direction sensor and speed sensor. Equipped with various functions such as a sensor output correction function that corrects the sensor output value; in order to execute these functions, it is necessary to manually operate the keys under the control mode corresponding to each function. There is. When performing such manual key operations, input keys are commonly used under each control mode, and so-called menus are created in which the manual input keys are assigned meanings corresponding to each control mode. One type is known. FIG. 1 shows a conventional example of this type of control mode switching system. That is, the conventional example shown in FIG. 1 allows direct transition from each control mode to any other control mode. For example, #1 from #2 control mode. #3. It is possible to directly shift to any of the #4 control modes.

The conventional example shown in Fig. 1 has the advantage that the control mode can be directly transferred from each control mode to any other control mode. Control means become complicated.

Therefore, when a specific control mode, that is, a control mode that displays a travel trajectory in correspondence with a map, is used frequently and other control modes are used less frequently, as in the case of the above-mentioned course guidance device, the second control mode is used. As illustrated in the figure,
A control mode is a method in which a specific control mode with a high degree of use @ variation (referred to as basic control mode in this specification), that is, control mode #1 shown in the figure, is used as a key station to shift to other control modes. This is preferable because it requires less hardware configuration of the switching means, reduces erroneous operations, and is compatible with the user's sense of operation. In other words, since the basic control mode described above can be regarded as the "main control mode" and the other control modes as "secondary control modes," the transition to each control mode should be made via the "main control mode" described above. This is why it is well suited to the sense of use.

The present invention has been made based on the above considerations, and an object of the present invention is to provide a key human power device that is compatible with a course guidance device and that can simplify control means for switching to a control mode. Therefore, the key human power device in the course guidance device of the present invention executes the key human power device in one control mode of each of the plurality of control modes in the key human power device in the course guidance device which has a plurality of control modes regarding course guidance of a moving object. In regards to
A plurality of function keys that can be used in common, a basic mode selection key that selects a predetermined basic control mode from among the plurality of control modes, and a control mode that selects each control mode other than the basic control mode. a plurality of general mode selection keys; a basic mode switching control unit that manually switches from a control mode other than the basic control mode to the basic control mode; and a key using the general mode selection key; It is equipped with a general mode switching control section that switches from the control mode to another control mode, and converts from one of the control modes other than the basic control mode to the other control mode other than the basic control mode. It is characterized by being structured so that it is carried out after being returned to the original state. This will be explained below with reference to the drawings.

FIG. 3 is a front view of a keyboard according to an embodiment of the present invention, and FIG. 4 is a block diagram showing the configuration of an embodiment of the present invention. Reference numeral 1 in the figure is a mode display section, lα to 1d is an indicator light indicating the #1 to #4 control mode and is composed of, for example, a display LED, and 2 is a control mode switching section, 2a to #4. 2C is the mode selection key for selecting #2 to #4 control mode, 3 is the key 14
3α to 3i are function keys, 4 is an end key, 5 is a D flip-flop, 6 is a gate with inhibit input, and 7 is a decoder.

Manual key operation in the present invention will be explained with reference to FIG. The embodiment shown in FIG. 3 is a case where there are four types of control modes, where #1 control mode is the basic control mode according to the present invention, and #2f, c to #4 control modes are other control modes. mode. The function keys 3a to 3i in the key manual section 3 are
It goes without saying that the keys 1 to #4i1711 are commonly used in any of the '1111 modes, but are performed with meanings corresponding to the respective control modes. c. Switching to a control mode other than the basic control mode described above, which is a disadvantage of the present invention, cannot be performed unless the state is once returned to the basic interval mode. For example, if the current resistance mode state is the #1 control mode (indicator lamp 1a is lit), it is possible to switch to the desired control mode by pressing any of the mode selection keys 2α to 2c.

Assume that the mode selection key 2a is pressed to switch to #2 control mode (at this time, the indicator light 1b lights up).
. In this state, it is not possible to switch to the #3 or 84 control mode even if the mode selection key 2b or 2C is pressed. That is, it is not possible to switch to control mode #3 or #4 until after the operation under the #2 control mode is completed and the mode is returned to #1 control mode by pressing the end key 4 ( In that sense, the above exit key 4 #l
(You can think of it as a key to select the control mode).

Next, turn off the control mode f! #1 Assistant work will be specifically explained with reference to FIG.

In FIG. 4, numerals 1 to 4 correspond to those in FIG. Then, the D-flip 70 tube 5 outputs a signal that is inverted by a human input signal from the end key 4 and a decoder 7, which will be described later. That is, ``2-note flip-flop 5
11/Il outputs a logic rlJ in response to an input signal from the end key 4, and inverts the output C and outputs a logic "0" in response to an input signal from the decoder 7. The gate 6 with inhibit input is the above-mentioned D flip
Based on the output signal of the 70 knob 5, the passage of key manual power from the control mode switching section 2 is prohibited or permitted. That is, in the embodiment shown in FIG.
When the output of the flip-flop 5 is logic "o", passage of the key input from the control mode switching unit 2 is prohibited IF, and when the output of the D flip-flop 5 is logic "1", the control mode is disabled. Passage of the key manually from the switching unit 2 is permitted, and information for selecting the #1 control mode is transferred to the decoder 7. The decoder 7 outputs the key power from the key power unit 3 based on the control mode corresponding to the control mode information from the gate 6 with input prohibition input. 9, that is, the key human power from the key human power unit 3 is given meaning based on the respective control modes and output. Furthermore, the decoder 7 displays a display corresponding to the control mode among the indicator lights 1a to i d (shown in FIG. In addition to outputting a signal to turn on the light, the above 1t! When the content of the I control mode information is one of the control modes #2 to #4 described above, a signal is output that inverts the output of the flip-flop 5.

Now, when the control mode of the key human power device of the present invention is the #1 control mode, that is, the output of the flip-flop 5 is logic "1", and the inhibit input side gate 6 is the key input from the control mode switching section 2-. When the decoder 7 is in the state where the passage of human power is permitted and the decoder 7 is in the state where the key human power from the key human power section 3 is outputted with a meaning corresponding to the upper 3C#1 control mode, it is possible to When the #2 mode selection key 2α (shown in FIG. 3) is pressed, the manual input of the key (#2 control mode selection information) is transferred to the decoder 7 via the inhibit input gate 6. The decoder 71d is switched to the #2 control mode, and as described above, the key power from the key power unit 3 is output as a key power having a meaning corresponding to the #2 control mode, and the display lamp 1b in the display unit 1 is output. Outputs a signal to turn on the upper He D flip-flop 5.
Outputs a signal that inverts the output of As a result, the output of the flip-70 switch 5 is inverted to the logic rOJ, and therefore, as described above, the prohibition input (=J gate 6) prohibits the passage of a new key input from the control mode switching unit 2.

Therefore, any subsequent key input from the control mode switching section 2 is not transferred to the decoder 7. That is, switching to a control mode other than #1 control mode in the present invention is prohibited.

By pressing the end key 4 at the time when the manual key operation under the #2 control mode is completed, the control mode in the manual key device of the present invention is changed to:
As mentioned above, returning to #1 control mode,
After that, switching to the control modes #2 to #4 can be performed manually using the keys of the control mode switching unit 2. Although the example shows a case where there are four types of control modes, the present invention is not limited to this, and there are multiple types of control modes other than four types. It goes without saying that it is possible to perform the same operation in the III control mode as well.

As explained above, according to the present invention, in a key human-powered device of a course guidance device having a plurality of control modes, when switching the control mode, one of the control modes other than the predetermined basic control mode is selected. By making it possible to switch to a control mode other than the basic control mode after returning to the basic control mode, the hardware configuration of the control mode switching means is simplified, and Erroneous manual key operations corresponding to each control mode can be prevented, and key manual operations can be performed that are well suited to the user's operating sense.
