Hereinafter, embodiments will be described.
FIG. 1 is a block diagram illustrating a configuration example of a vehicle navigation device according to the present embodiment.
The navigation computer 1 processes the data input from the operation member by the user, the data fetched from various sensors, the map / road data read from the memory such as the DVD and the hard disk, and the data necessary for various navigation guidance to display the display 11. Has a function of performing various kinds of guidance by using display guidance by the voice guidance and voice guidance by the speaker 12 together. For this reason, the navigation computer 1 includes various buttons 5 for user operation and input, a touch panel 6 for touching the screen to switch and scroll the guidance screen, voice input and Bluetooth (Bluetooth: registered trademark name). A microphone 7 or the like for use in a wireless communication system is connected. Note that the touch panel 6 is usually arranged on the front surface of the display 11 and integrated. Further, the navigation computer 1 calculates the vehicle position based on the speed signal and the position signal input from the vehicle speed sensor 2 and the GPS receiver 10 for detecting the vehicle position, and displays the calculated vehicle position on the guidance map on the display 11. When the TV signal is received by the TV antenna 9, the navigation computer 1 displays a TV image on the display 11 when the vehicle is stopped, etc., and captures a captured image from the back camera 8 and displays it on the display 11 when the vehicle is reversed. To do. Further, an on / off detection line is connected from the parking brake 3, and the navigation computer 1 determines whether or not the vehicle is in a stopped state.

  In the present embodiment, a line for detecting the position (shift mode) of the shift lever 4 for switching the state of the transmission provided in the vehicle is connected to the navigation computer 1. Depending on the position of the shift lever 4, one of a plurality of modes such as parking, neutral, drive, low, and reverse is selected, and the navigation computer 1 can detect the position of the shift lever 4 and use it according to the detected position. The operation function of the navigation device is changed (details will be described later). Therefore, control means for changing the operation function of the navigation device that can be used according to the shift mode is provided. Thus, in this embodiment, it is characterized by controlling various operation functions of navigation performed on the guidance screen according to the position of the shift lever 4, and the shift lever is always operated in each traveling state from the stop state, Since the user's intention can be known in advance by the operation, detailed guidance according to the state of travel can be given to the user. The shift lever is used by the user to select the gear ratio of the vehicle, such as parking, neutral, drive, low, reverse, etc., and the overdrive mode is canceled so as not to switch over a certain gear ratio. It is also possible to select a manual transmission mode (manual mode) in which the gear ratio can be manually switched. In the present embodiment, it is not necessarily limited to the form of a shift lever, but any member (shift member) for selecting a gear ratio of a vehicle, such as a button type, a switch type, or a combination thereof, However, in the following description, the term shift lever will be used for convenience.

FIG. 2 is a diagram for explaining the relationship between the shift lever position and the navigation operation function.
When the shift lever position is P (parking), all navigation operation functions can be selected as in the conventional case. When the shift lever is in the R (reverse) position, it is necessary to pay attention to the rear of the vehicle. In addition to the map operation function (map display and display map operation such as enlargement / reduction and movement), the back camera operation Function can be selected. When the shift lever position is N (Neutral), there are many cases that temporarily stop and look for a convenience store or a gas station, so the function of manipulating the map (map display and map operation such as enlargement / reduction and movement) In addition, it is possible to select a display change operation function (for example, change of an icon displaying a peripheral facility). When the shift lever position is D (drive), the function is limited to a map operation function (map display and display map operation such as enlargement / reduction and movement). As described above, the operation function of the navigation device is set according to the shift mode. In this embodiment, when the shift mode is parked, there are many functions that can be used compared to the neutral and drive modes. At times, there are fewer functions available than when neutral and parking.

  When the shift lever position is 1st gear (low), that is, when using forward engine brakes that are stronger than the normal drive position, there are many cases of traveling on mountain roads and so on. In addition to display and operation of the display map such as enlargement / reduction, movement, etc., a specific guidance display function such as a gas station or a break facility is added, and a function such as character enlargement is enabled. Although the case where the shift lever position is low is given as an example, the same applies to the case of releasing the second speed (second), overdrive mode, or manual mode because it aims at powerful engine braking. is there.

  On the other hand, as a navigation device function, there are fuel efficiency information guidance functions related to vehicle driving and eco-driving functions such as an eco-drive function that advises accelerator operation to promote low fuel consumption, but the shift lever position is low, etc. However, since there are many cases of driving on mountain roads, the fuel consumption display function is disabled.

  In this way, the navigation guidance screen is displayed differently when the shift mode is drive and low, and the navigation guidance screen is different between the automatic transmission mode and the manual transmission mode. The navigation function is controlled so that Since the shift lever position reflects the situation where the vehicle is placed (the driving mode of the vehicle), the navigation operation function can be changed according to the position of the shift lever, and fine guidance can be performed.

FIG. 3 is a diagram illustrating an example of a guidance screen.
A plurality of operation buttons are provided at the bottom of the screen. FIG. 3A shows a case where the “menu” button is operated when the shift lever position is P, and “route setting” and “registered location setting” are displayed on the screen. ”,“ GPS information ”,“ guidance information ”,“ auxiliary function ”, and the like are displayed, and various functions are executed by operating these buttons. FIG. 3B shows a case where the “map” button is operated when the shift lever is in the neutral position, and a “neighboring facility” button is displayed on the screen in addition to the map. Facilities such as stands are displayed together with icons, and the display of these icons can be changed.

FIG. 4 is a diagram showing a processing flow for changing the operation function.
In the operation function change, it is determined whether or not the shift lever position is P (parking) (step S1), and if it is P, all functions can be selected. If the shift lever position is not P in step S1, it is determined whether or not the shift lever position is R (reverse) (step S2). If it is R, the map operation function (map display and enlargement / reduction, movement, etc.) Back camera operation function is added in addition to (Operation). If the shift lever position is not R in step S2, it is determined whether or not the shift lever position is N (neutral) (step S3). If N, the display change function is added to the map operation function. If the shift lever position is not N in step S3, it is determined whether or not the shift lever position is D (drive) (step S4). If the shift lever position is not D in step S4, it is determined whether the shift lever position is forward in 1st speed, 2nd speed, or manual mode (step S5), and if it is forward in 1st speed, 2nd speed, or manual mode. Add specific guidance function and character enlargement function to map operation function, and disable eco-drive display function. If it is not forward in the first speed, the second speed, or the manual mode in step S5, the process returns to step S1 and the same processing is performed.
