  A feature of the present invention is that when the vehicle stops, the stop state is determined, and a menu screen corresponding to that is displayed. For the sake of safety, the driver is restricted from operating the navigation device while the vehicle is running. Therefore, the operation by the driver is generally performed using the timing when the vehicle stops. In view of these points, the present invention does not always present the same operation screen to the user when the vehicle is stopped, but predicts an operation to be performed next by the user according to the state when the vehicle is stopped. By presenting a menu screen that allows an expected operation to be executed immediately, a user's operation procedure and operation time are reduced, and a simple operation is realized.

  FIG. 3 is a diagram illustrating the relationship between the stop state of the vehicle in the present embodiment and the operation that the user will request next. For example, when the engine is started or when the navigation device is started, the user is expected to set a destination and search for a route to the destination, or to select music.

  When stopping at the intersection signal at the time of route guidance to the destination, check the current route to check the corners and landmarks of the next intersection, etc., or grasp the relative position of the current location Therefore, it is expected to check the entire route.

  When the route to the destination is guided, when the vehicle stops at a stop on the way, it is expected to check the route to the next stop (destination) or the entire route. When the route to the destination is shown, if the vehicle stops near the destination due to a signal, etc., obtain information indicating the location of the destination and obtain a more detailed road map to the destination. It is expected to increase the scale of the map for viewing and to search for parking lots around the destination. When the vehicle stops after the route guidance ends, it is expected to set a route for returning to the current road or to search for restaurants and facilities around the destination. When a vehicle stops due to traffic jams, search for a detour route to bypass the traffic jam, obtain traffic jam information such as the distance of the traffic jam and how long the jam will last, and change the audio selection Is expected. When a vehicle stops near a station, it is expected to see a timetable of a train or bus that arrives at or departs from the station.

  Whether or not to display a screen according to the stop condition as described above can be selected in advance by the user. For example, a mode setting screen 90 as shown in FIG. 4 can be used to set whether the screen display according to the stop state is 92 or the normal screen display is 94. This setting information is stored in the storage device 30, for example.

  Next, a display method on the display according to the stop state of the vehicle will be described. First, when the vehicle is started (this is also an aspect of a stopped state), as shown in the flowchart of FIG. 5, the ignition switch is turned on (step S101), and the navigation apparatus 1 is linked in conjunction with the ignition switch. When activated (step S102), the control unit 80 loads the menu screen control program 64 from the storage device 30 or the program memory 60 and executes it (step S103). The control unit 80 checks whether or not a screen display mode corresponding to the stop state is set (step S104), and when the mode is set, unlike the normal initial screen, as shown in FIG. A menu screen corresponding to the engine start is displayed (step S105). FIG. 6 shows an example in which the display 51 is displayed on two screens. A map around the vehicle position M is displayed on the large screen 51a on the left side, and the operation buttons 101 and 102 predicting the user's request on the small screen 51b on the right side. Is displayed. The operation button 101 is an input for requesting to set a destination and searching for a route to the destination, and 102 is an input for requesting audio selection.

  For example, when the user selects and inputs the destination setting operation button 101 using a remote controller or the like (step S106), the control unit 80 activates the route search program 61 and performs a sequence operation for setting the destination in accordance therewith. Start (step S107). When the user selects and inputs the operation button 102 for audio music selection (step S108), the control unit 80 activates a program for audio music selection and starts an audio music selection operation (step S109). When the input to these operation buttons 101 and 102 is not performed for a certain period of time, or when the operation button 103 for returning to the normal initial menu screen is selected and input, the display is switched to the normal initial menu screen (step) S110).

  Next, a screen display when the vehicle stops while traveling will be described with reference to an operation flowchart of FIG. In the following example, it is assumed that a mode for performing screen display according to the stop state is set.

  While the vehicle is traveling, the GPS receiver 10 and / or the autonomous navigation sensor 11 detects the current position of the vehicle (step S201). The control unit 80 reads the corresponding map data from the storage device 30 based on the current position of the vehicle received from the GPS receiver 10 or the like, and displays a map around the vehicle position on the display 51 via the display control unit 50 ( Step S202).

  When the vehicle stops, the vehicle speed sensor (included in the self-contained navigation sensor 11) outputs a signal indicating that the speed is zero, and a signal indicating that the parking brake is turned on is output from the vehicle state information section 78. When these output signals are input, the control unit 80 detects that the vehicle has stopped (step S203). When the stop of the vehicle is detected, the control unit 80 determines the stop state of the vehicle according to the menu screen control program 64 (step S204).

  In the present embodiment, the stop state is determined as 1 to 7 as shown in FIG. 2, but the stop states 2 to 7 are determined when stopping while the vehicle is running. The control unit 80 compares the vehicle stop position obtained from the GPS receiver 10 with the map data in the storage device 30 and determines the vehicle state. For example, if the stop position is on an intersection road during route guidance, the stop state is determined to be “2”. At the time of route guidance, if the stop position is near a preset stop-off place, it is determined that the stop state is “3”. An appropriate value can be set in advance as to whether or not the vehicle is near the stop. For example, when the vehicle stops within a radius of 50 meters from the stop, it is determined that the stop state is “3”.

  At the time of route guidance, when the stop position is in the vicinity of the destination, it is determined that the stop state is “4”. An appropriate value can be set in advance as to whether or not the vehicle is in the vicinity of the destination. For example, when the stop position is within 3 kilometers of the road distance from the destination, or the road from the departure point to the destination When the vehicle travels over 95% of the distance and stops, it can be in the vicinity of the destination. When the vehicle stops after the route guidance ends, it is determined that the vehicle is in the stopped state “5”. The end of route guidance is, for example, when the vehicle reaches the destination and the route guidance guide ends there.

  When traffic information can be obtained by VICS or the like, and the vehicle is stopped on a road with traffic congestion, it is determined that the vehicle is in a stopped state “6”. Finally, when the stop position of the vehicle stops near the station, it is determined that the stop state is “7”.

  The control unit 80 determines the stop state, and sets a flag in the corresponding stop state as shown in FIG. 2 based on the determination result (step S205). When the stop state does not correspond to any of 2 to 7, a normal menu screen (default screen) is displayed. On the other hand, when there are a plurality of corresponding stop states, for example, any one stop state is selected according to the priority order of the stop states 1 to 7 shown in FIG.

  Next, the control unit 80 displays a menu screen corresponding to the determination result on the display 51 (step S206). For example, when it is determined that the vehicle has stopped near the destination (stop state “4”), a screen as shown in FIG. FIG. 11A shows an example in which a plurality of buttons 110 to 118 predicting the user's request are displayed on the screen on which the map around the vehicle position is displayed, and FIG. In this example, a plurality of buttons 110 to 118 are displayed like a menu screen on a small screen of the two screens. The peripheral search button 110 is an input for starting a search for restaurants and facilities around the destination. The parking lot search button 112 is an input for starting a search for parking lots around the destination. The destination information button 114 is an input for obtaining information about the destination (what the destination is). The one-shot enlargement button 116 is an input for changing the scale of the map so that the destination and the stop position fit on the screen. For example, around a destination, a narrow road such as a narrow street may be passed, and it is expected that the map is viewed at a magnification as large as possible while grasping the position of the destination. The normal screen button 118 is an input for switching the display from the screen corresponding to the stop state to the normal screen.

For example, when it is determined that the vehicle has stopped on a congested road (stop state “6”), a screen as shown in FIG. 9 is displayed on the display 51 (step S206).
In FIG. 5A, operation buttons 120 to 128 are combined and displayed on a map around the vehicle position, and in FIG. 4B, operation buttons 120 to 128 are displayed as menus on separate screens. On the map, a vehicle mark M and a road R in traffic jam are shown. The detour route button 120 is an input for searching for a detour route for avoiding traffic congestion and displaying the detour route. The traffic jam information button 122 is an input for obtaining detailed VICS information such as how many minutes the traffic jam will continue. The audio / TV button 124 is an input for selecting music or operating the TV in order to distract the boredom in a traffic jam. The peripheral search button 126 is an input for searching a nearby restaurant or facility in order to temporarily pass the traffic. The normal screen button 128 is an input for switching the display from the screen corresponding to the traffic jam state to the normal screen.

  Similarly, operation buttons indicating a user request (see FIG. 3) predicted from the stop state are displayed on the display 51 in other stop states.

  When there is a selection input from the user for the operation buttons displayed on these screens (step S207), the control unit 80 starts a program for executing the operation buttons and starts a processing sequence (step S208). For example, in FIG. 9, if the user selects and inputs the bypass route button 120, the display searches for a route that bypasses the traffic jam portion (shaded area) and displays the route R1.

  As described above, according to the present embodiment, when the vehicle stops, the operation buttons reflecting the user's operation predicted next from the stop state are displayed, so that the user's operation procedure is reduced. Therefore, the convenience of the navigation device can be further improved.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.
