  FIG. 1 is a block diagram showing a configuration of an embodiment of a navigation apparatus according to the present invention. The navigation device 100 is mounted on a vehicle and is operated by a user. An operation device 101, a vehicle speed sensor 102 that detects the vehicle speed of the host vehicle, and a GPS that receives a GPS signal from a GPS satellite and detects the current location of the host vehicle. A unit 103, a vibrating gyroscope 104 for detecting the traveling direction of the host vehicle, a map disk 105a for storing map data, for example, a disk reading device 105 for reading a DVD, a control device 106, a monitor 107, and a speaker 108 are provided. ing.

  As shown in FIG. 2, the operating device 101 is configured such that the user grips the grip portion 101h, and the X, Y, and Z axes in the X, Y, and Z coordinate systems with the operation fulcrum 2a of the grip portion 101h as the origin. An X-axis direction force sensor 101a, a Y-axis direction force sensor 101b, and a Z-axis that detect forces applied in the three directions (X, Y, Z) of the grip portion 101h when a force is applied in any of the directions A directional force sensor 101c is provided. Further, when the user rotates the grip portion 101h around any one of the X axis, the Y axis, and the Z axis, that is, when the user rotates the grip portion 101h in any direction of α, β, and γ, the grip portion It has an α-direction rotational torque sensor 101d, a β-direction rotational torque sensor 101e, and a γ-direction rotational torque sensor 101f that detect rotational torque in three directions (α, β, γ) of 101h. Furthermore, it has a touch sensor 101g that detects that the user has gripped the grip portion 101h. Detection signals detected by the sensors mounted on the operation device 101 are output to the control device 106.

  The control device 106 reads a map of a predetermined range around the current position of the host vehicle detected by the GPS unit 103, for example, a map of 2 km around from the map disc 105a via the disc reader 105, and marks the position of the host vehicle on the read map. Is drawn and displayed on the monitor 107. At this time, the map is generally displayed so that the traveling direction of the host vehicle detected by the vibrating gyroscope 104 is at the top of the screen, and is displayed at a predetermined scale and a predetermined look-down angle that are preset and stored in the memory 106a.

  In the navigation device according to the present invention, the user can change the display form of the map displayed on the monitor 107 by operating the operation device 101. That is, the user operates the grip unit 101h to perform operations such as scrolling the map displayed on the monitor 107 in any direction, rotating the map, changing the scale, and changing the look-down angle. Is possible. The display mode setting data changed by the user is stored in the memory 106a. When the navigation device 100 is activated next time, the setting data is read from the memory 106a, and a map is displayed on the monitor 107 based on the setting data.

  In the present embodiment, the look-down angle of the map can be continuously changed at a predetermined angle interval, for example, 1 degree interval, and the map displayed on the monitor 107 when the look-down angle is 90 degrees is a flat surface. It becomes a figure, and it becomes a bird's-eye view in the case of other look-down angles.

  Hereinafter, processing for changing the display form of the map based on the operation of the operation device 101 by the user will be described. When the user holds the grip portion 101h, a detection signal from the touch sensor 101g is output to the control device 106. The control device 106 executes processing based on output signals from the other sensors output from the operation device 101 only while detecting an output signal from the touch sensor 101g. As a result, the display form of the map is changed when each sensor of the operating device 101 detects a force due to vibration of a running vehicle or the like even though the operating device 101 is not operated by the user. Can be prevented.

  Further, when a force in each direction and a rotational torque are detected from each sensor mounted on the controller device 101, the process is executed based on the output from the sensor having the largest detected value. Therefore, in the present embodiment, the following description will be given on the assumption that the user operates the grip portion 101h in the direction in which the largest detection value is output.

  When the user grips the grip portion 101h and operates in the X-axis direction, that is, when a force in the X-axis direction is detected by the X-axis direction force sensor 101a, the map displayed on the monitor 107 is scrolled horizontally. To do. For example, the map is scrolled to the right when a force in the X-axis positive direction is detected by the X-axis direction force sensor 101a, and the map is scrolled to the left when a force in the negative X-axis direction is detected. Further, when the user grips the grip portion 101h and operates in the Y-axis direction, that is, when a force in the Y-axis direction is detected by the Y-axis direction force sensor 101b, the map displayed on the monitor 107 is displayed. Scroll vertically. For example, if a force in the positive Y-axis direction is detected by the Y-axis direction force sensor 101b, the map is scrolled up, and if a negative force in the Y-axis is detected, the map is scrolled down.

  Note that the horizontal scroll and vertical scroll of the map continue to be scrolled at a predetermined scroll speed while the grip unit 101h is operated by the user. FIG. 3 is a diagram illustrating an example of a change in the display form of the map displayed on the monitor 107 when a force in the Y-axis positive direction is detected by the Y-axis direction force sensor 101b. When the map shown in FIG. 3A is displayed on the monitor 107, the user operates the grip portion 101h in the positive direction of the Y axis, and the map is scrolled up as shown in FIG. 3B. An example is shown.

Change the scale by changing the height. For example, the map is reduced when a Z-axis positive force is detected by the Z-axis direction force sensor 101c, and the map is enlarged when a Z-axis negative force is detected. Note that the map enlargement / reduction continues to change the map display magnification at a predetermined change rate while the grip portion 101h is operated by the user.

When the map shown in FIG. 4A is displayed on the monitor 107, an example in which the grip portion 101h is operated in the negative direction of the Z-axis by the user and the map is enlarged as shown in FIG. Is shown.

  When the user grips the grip portion 101h and rotates it in the α direction by tilting in the X-axis direction, that is, when the α direction rotational torque sensor 101d detects the rotational torque in the α direction, and the user grips the grip portion 101h. Is tilted in the Y-axis direction and rotated in the β direction, that is, when the β-direction rotational torque sensor 101e detects the rotational torque in the β direction, the angle at which the map 107 displayed on the monitor 107 is looked down To change. For example, when the rotation torque of the right rotation about the X axis is detected by the α direction rotation torque sensor 101d, the look-down angle with respect to the X axis direction of the map is increased, and when the rotation torque of the left rotation is detected. Decrease the look down angle of the map with respect to the X axis direction of the map. Further, when the rotation torque of the right rotation about the Y axis is detected by the β direction rotation torque sensor 101e, the look-down angle with respect to the Y axis direction of the map is increased, and when the rotation torque of the left rotation is detected. Decrease the look-down angle with respect to the Y-axis direction of the map.

  Note that the change in the look-down angle continues to increase or decrease the look-down angle every predetermined angle interval, for example, 1 degree while the grip portion 101h is operated by the user. As described above, when the looking-down angle is 90 degrees, the map is a plan view. FIG. 5 is a diagram schematically illustrating an example of a change in the look-down angle when a clockwise rotation torque is detected around the X axis by the α-direction rotation torque sensor 101d. When the map shown in FIG. 5 (a) is displayed on the monitor 107, the grip portion 101h is rotated to the right in the α direction by the user, and as shown in FIG. An example in which the looking down angle is increased is shown.

  When the user grips the grip portion 101h and rotates it in the γ direction, that is, when the rotational torque in the γ direction is detected by the γ direction rotational torque sensor 101f, the map displayed on the monitor 107 is rotated. . For example, the map is rotated to the right when the right rotation torque is detected around the Z axis by the γ direction rotation torque sensor 101f, and the map is rotated when the left rotation torque is detected around the Z axis. Rotate left. In addition, rotation of a map continues rotation of a map every predetermined rotation angle, for example, every 10 degrees, while the grip part 101h is operated by the user.

  FIG. 6 is a diagram illustrating an example of a change in the display form of the map displayed on the monitor 107 when the rotational torque of the right rotation about the Z axis is detected by the γ direction rotational torque sensor 101f. When the map shown in FIG. 6A is displayed on the monitor 107, the grip portion 101h is rotated rightward in the γ direction by the user, and the map is rotated rightward as shown in FIG. 6B. An example is shown.

  FIG. 7 is a flowchart showing the flow of processing in the navigation device 100 according to the present invention. The processing shown in FIG. 7 is executed by the control device 106 as a program that starts when the navigation device 100 starts operating. In step S <b> 10, a map in a predetermined range around the current position of the host vehicle is read from the map disk 105 a via the disk reading device 105. Thereafter, the process proceeds to step S20, where the setting data of the map display form displayed on the monitor 107 is read from the memory 106a, and the process proceeds to step S30. In step S30, a map is displayed on the monitor 107 based on the read setting data, and the process proceeds to step S40.

  In step S40, it is determined whether an output signal from the touch sensor 101g is detected. If an output signal from the touch sensor 101g is detected, it is determined that the user has gripped the grip portion 101h, and the process proceeds to step S50 to start detecting output signals from the force sensors and the rotational torque sensor. . Then, it progresses to step S60 and it is judged whether the output signal was detected from the force sensor and the rotational torque sensor. If it is determined that the output signal is detected from the force sensor and the rotational torque sensor, the process proceeds to step S70.

  In step S70, the display form of the map displayed on the monitor 107 is changed based on the output signals from the detected force sensor and rotational torque sensor. At this time, when output signals are detected from a plurality of sensors, the display form of the map is changed based on the output signals from the sensor having the largest detected value. Thereafter, the process proceeds to step S80, and the changed display form, that is, the map setting data currently displayed on the monitor 107 is stored in the memory 106a.

  Thereafter, the process proceeds to step S90, and it is determined whether or not an ignition switch (not shown) is turned off. If it is determined that the ignition switch is not turned off, the process returns to step S40 and the above-described processing is repeated. On the other hand, if it is determined that it has been turned off, the process ends.

According to the present embodiment described above, the following operational effects can be obtained.

Accordingly, the user can change various display forms by operating the grip unit 101h, and can improve the operability of the navigation device.
(3) The operation of the grip part 101h by the user is detected only while the output signal from the touch sensor 101g is detected. Accordingly, it is possible to prevent detection of an operation signal of the operation device 101 due to vibration of the traveling vehicle or the like.

In addition, it can also deform | transform as follows.

However, each may be scrolled in the opposite direction. That is, the map is scrolled to the left when the X-axis direction force sensor 101a detects a force in the X-axis positive direction, and the map is scrolled to the right when a force in the X-axis negative direction is detected. When the force in the positive Y-axis direction is detected by the Y-axis direction force sensor 101b, the map may be scrolled down.

Further, when the rotation torque of the right rotation about the Y axis is detected by the β direction rotation torque sensor 101e, the look-down angle with respect to the Y axis direction of the map is increased, and when the rotation torque of the left rotation is detected. The look-down angle with respect to the Y-axis direction of the map was made small. However, when the rotation torque of the right rotation about the X axis is detected by the α direction rotation torque sensor 101d, the look-down angle with respect to the X axis direction of the map is reduced, and when the rotation torque of the left rotation is detected. Increase the map look-down angle with respect to the X-axis direction of the map. Further, when the rotation torque of the right rotation about the Y axis is detected by the β direction rotation torque sensor 101e, the look-down angle with respect to the Y axis direction of the map is reduced, and when the rotation torque of the left rotation is detected. You may enlarge the looking down angle with respect to the Y-axis direction of a map. Further, the change of the look-down angle is determined by continuing to increase or decrease the look-down angle at a predetermined interval while the grip portion 101h is operated by the user. For example, the change is predetermined every time the grip portion 101h is operated once. The look-down angle may be increased or decreased at intervals of.

(5) When the rotation torque of the right rotation about the Z axis is detected by the γ direction rotation torque sensor 101f, the map is rotated to the right, and when the rotation torque of the left rotation about the Z axis is detected The map was rotated left. However, the map is rotated to the left when the γ-direction rotational torque sensor 101f detects a clockwise rotation torque about the Z axis, and the map is rotated when a counterclockwise rotation torque is detected about the Z axis. May be rotated clockwise. Further, the rotation of the map is continued for each predetermined rotation angle while the grip portion 101h is operated by the user. For example, the rotation of the map is predetermined every time the grip portion 101h is operated once. The map may be rotated at a rotation angle of.
