In addition, the control unit 23 writes and reads positioning information obtained from the GPS receiving unit 21 and acceleration information obtained from the acceleration sensor 22 to and from the memory unit 24. Further, the control unit 23 detects an operation input of the operation unit 25, performs processing according to the input content, and performs display control of the display unit 26.

  The memory unit 24 corresponds to the storage unit in claim 13, and constitutes the user status identification unit and position calculation unit of the claim together with the control unit 23. The memory unit 24 stores the following program, for example. The memory unit 24 stores a program for determining the speed of the mobile phone (the user carrying the mobile phone) from the positioning information and the time information, and determining whether the user is traveling in the car by comparing with a predetermined threshold. Yes. The memory unit 24 stores a program that realizes a pedometer function from acceleration information, obtains the number of steps per unit time as needed, and compares it with a predetermined threshold value to determine whether or not the user is walking. . In addition, the memory unit 24 incorporates map information such as roads and parking lots, and incorporates a part of the running route, a walking start position (vehicle parking position), and a part of the walking route. A program that links the map information and displays it on the display unit 26 is stored.

  The operation unit 25 includes operation buttons, and accepts operation contents input by the user and transmits them to the control unit 23.

The display unit 26 is a display unit that displays data requested by the user and a device state on an LCD (Liquid Crystal Display), an organic EL (Electroluminescence) display, or the like.

  Next, the operation of the mobile phone according to this embodiment will be described. FIG. 3 is a flowchart showing the flow of the vehicle position calculation operation performed by the mobile phone of this embodiment. The operation described below is started by a position calculation command input from the user's operation unit 25, and immediately after the command is input, the running flag (whether the user is running or not) held in the memory unit 24 by the control unit 23. The value of the variable that holds whether or not) is set to OFF (not traveling). As a premise, it is assumed that the user inputs a command before the user parks the host vehicle in the parking lot.

  First, the control unit 23 stores the current time information and the positioning information obtained from the GPS receiving unit 21 as a variable Y in the memory unit 24 (step S301). Next, the control unit 23 substitutes the time information and positioning information (variable Y) saved immediately before into the variable X (step S302), and again stores the current time information and the positioning information obtained from the GPS receiving unit 21 in the memory unit. 24 is stored as a variable Y (step S303). Then, the moving time and moving distance are obtained from the difference between the variable X and the variable Y, and the moving speed v is calculated (step S304).

Here, the moving speed v is compared with the travel determination threshold value V _D stored in the memory unit 24 to determine whether or not the vehicle is traveling (step S305). When the moving speed v is larger than the travel determination threshold value V _D (step S305 / YES), it is determined that the user is traveling, the traveling flag is set to ON (running) (step S306), and the variable Y information is set. The travel position list is recorded (step S307). Incidentally, the travel position list, as shown in FIG. 4, the time information (Date / Time), location information (the Location) shall hold up to maximum of N _D, the time information and position information exceeds matter N _D Is overwritten on the data indicating the oldest time in the travel position list. The travel position list and the maximum number of records _ND are stored in the memory unit 24.

On the other hand, when the moving speed v is equal to or less than the travel determination threshold value V _D (step S305 / NO), it is determined that the user is not traveling, the number of steps w per unit time and the walking determination threshold value W held in the memory unit 24. _It is determined whether or not the user is walking by comparing _min and W _max (step S308). Here, in the present embodiment, the control unit 23 always counts the number of steps by the pedometer function realized by the acceleration sensor 22, the control unit 23, and the memory unit 24, and constantly calculates the number of steps w per unit time. To do. When the number of steps w is within the walking determination threshold values W _min and W _max , that is, when the number of steps w is larger than the threshold value W _{min and} smaller than the threshold value W _max (step S308 / YES), it is determined that the user is walking.

At this time, the in-walking flag is confirmed, and when the setting content is ON (step S309 / YES), the in-running flag is set to OFF (step S310). And the information of the variable Y is recorded on the 1st of a walking position list | wrist (step S311). Here, the first information recorded in the walking position list is time information and position information at the time when the determination is switched from the running state to the walking state, and the point indicated by the position information is the walking start point. Since possibility is high, the control part 23 estimates this walking start point as a parking position of a vehicle. As shown in FIG. 5, the walking position list holds time information (Date / Time) and position information (Location) up to a maximum of N _W cases, and time information and position information exceeding N _W cases. Is not recorded in the walking position list. The walking position list and the maximum number of stored cases N _W are stored in the memory unit 24.

  When the setting of the walking flag is confirmed and the running flag is not ON (OFF) (step S309 / NO), the variable Y information is recorded in the walking position list (step S314). This means that the running flag is OFF at the time of the walking determination (step S308) indicates that the walking determination has been made while switching from ON to OFF, and the information on the walking start point has already been obtained. Since it is recorded in the first line of the walking position list, when the running flag is OFF at the time of walking determination, time information and position information are continuously recorded after the second line of the walking position list.

When it is determined by walking determination that the vehicle is not walking, that is, when the number of steps w is outside the range of the walking determination threshold values W _min and W _max (the number of steps w is equal to or less than the threshold value W _min or the number of steps w is equal to or greater than the threshold value W _max ). / NO) determines whether or not the traveling flag is ON (step S312). If ON (step S312 / YES), the variable Y information is recorded in the traveling position list (step S313, step S307). If it is OFF (step S312 / NO), the information of the variable Y is recorded in the walking position list (step S314).

When any of the recording to the travel position list (step S307), the recording to the head of the walking position list (step S311), and the recording to the continuation of the walking position list (step S314) is completed, the process is saved immediately before. time information and positioning information by substituting (variable Y) to a variable X (step S302), and later, the same process is repeated at a predetermined cycle I _t. The repetition of the cycle I _t is kept held in the memory unit 24.

  And when the display of a vehicle position is requested | required by the input from the operation part 25, etc., as shown in FIG. 1, the control part 23 will show the parking position of a vehicle, its surrounding map, the travel route before parking, and after parking. Are immediately displayed on the display unit 26. Specifically, the parking position of the vehicle is displayed by the position information in the first row of the walking position list recorded as the walking start position, and the travel route before parking is the position in time series order recorded in the travel position list. The walking path after parking is displayed by the position information in the order of time series recorded after the second line of the walking position list.

Here, various variable that holds the memory unit _{24 (V D, N D,} W min, W max, N W, I t) for, may be a fixed value, or may be a variable value. As for the I _t, step S301, step S307, step S311, by determining via the one of step S314, the may be separately fixed values may be configured each value as possible changes. When variable values of various variables are used, adjustment may be made by a user of the mobile phone. In addition, the user can set whether to enable or disable the above-described operation in this embodiment, and the setting content is stored in the memory unit 24. When the above operation in the present embodiment is set to be invalid, the operation of the flow shown in FIG. 3 may not be performed.

  According to the present embodiment, a part of a travel route of a vehicle on which a user carrying a mobile phone rides, a walking start point (a parking position of the vehicle), and a part of the walking route are automatically recorded without being conscious of the user. Thus, it is possible to easily and quickly specify the position of the vehicle in the parking lot by an inexpensive means without adding a new device to the vehicle.
