Although the details will be described later, one or more, usually a plurality of travel plans are created by a predetermined algorithm based on the current position, the external condition, the travel condition, and the user state recognized by the current status recognition unit 111.

The input / output control unit 113 controls the data input / output to / from the ECU 11. The input control controls the input data by the user operating and setting the user setting unit 142 (input key, touch sensor). In the output control, based on the travel plan created by the travel plan creation unit 112, the images stored in the map data unit 131, the area data unit 132, and the user data unit 133 of the database unit 13 are selected and displayed on the monitor 24. Control the display. Further, the speaker 25 is controlled to output the voice stored in the database unit 13 and the voice synthesized based on the created travel plan.

The travel plan proposal device 1 having the above configuration uses an in-vehicle power source for which the description is omitted as electric power, and is driven at the same time as the navigation system 2. Alternatively, in a situation where the navigation system 2 is being driven, it may be driven by turning on a dedicated power switch.

Next, the operation of the travel plan proposal by the travel plan proposal device 1 will be described with reference to the flow chart of FIG. An example of the display form of the monitor 24 in the main step is shown in FIGS. 5 and 6. When the power of the navigation system 2 is turned on, the navigation system 2 is in a normal operating state (step S11: the same applies hereinafter). At this time, the monitor 24 displays map information including the display of the current position, a route to the travel destination set by the user, and the like. In addition, sound is output from the speaker 25 as needed.

When the user turns on the power of the travel plan proposal device 1, the ECU 11 waits for the input of the start signal (S12, FIG. 5A). Here, an example of using the touch sensor of the monitor 24 is shown. When the start signal is input to the ECU 11 by the user's operation, the ECU 11 immediately executes the travel plan creation (S13, FIG. 5B). The creation of this travel plan will be described later, but the travel plan creation unit 112 uses a predetermined algorithm to create one or more travel plans based on the current position, the external condition, the travel condition, and the user state recognized by the current status recognition unit 111. , Here we create multiple travel plans.

When the travel plan is created (S14), the ECU 11 controls the output unit 15 (monitor 24) by the input / output control unit 113 and inquires the user whether or not to display the travel plan (S15, FIG. 5 (S15). c)). When the user denies the display, the travel plan is not displayed on the monitor 24. In this case, the so-called travel destination becomes a secret "mystery tour", and the input / output control unit 113 sets one of the created plurality of travel plans. This setting may be based on a preset priority or may be selected by lottery. The set travel destination is not displayed on the monitor 24, and only the map information for guiding the travel destination set by using the navigation system 2 is displayed (S16, FIG. 5 (d)). If the user drives a car according to this map guide, he / she will reach a secretly set destination.

If the user wishes to display in step S15, the input / output control unit 113 displays the created plurality of travel plans on the monitor 24 and makes a proposal (S17, FIG. 6A). Here, a list of a plurality of (three) travel plans is displayed, and if the user "selects" one of them by the user setting unit 142 (touch sensor) and "references" at the same time (S18), the monitor 24 is displayed. The travel destination of the selected travel plan and its area information are displayed (S19, FIG. 6B). At the same time, the speaker 25 may notify by voice. The travel plan may be displayed in order in a preset priority order. In this case, the travel destination and the area information of the travel destination are displayed in order, and at the same time, the travel destination is notified by voice.

Returning from the display of the area information in step S19 (FIG. 6 (b)), the process waits for a decision as to whether or not to make a decision on the proposed plurality of travel plans (S20, FIG. 6 (c)). The user selects one of the proposed traveling plans and makes a "decision". If "Random" is selected without selecting "Decision", the ECU 11 determines the most preferable travel plan (S21). When the travel plan is determined, the determined travel plan is displayed on the monitor 24 (S22, FIG. 6D). As the display of this travel plan, map information up to the travel destination of the travel plan is displayed. At the same time, the area information of the travel destination shown in FIG. 6B is displayed as appropriate. Further, the speaker 25 informs the travel destination area information by voice. The user can reach the proposed destination by driving according to this display or notification.

In the above flow, the input is set by the key operation or the touch sensor operation by the user. However, when the sensor unit 12 or the input unit 14 is equipped with a microphone for detecting the user's voice, the voice uttered by the user is output. It may be recognized and the input is set.

With reference to FIG. 7, the flow of the operation of creating the travel plan in the travel plan creation unit 112 described above will be described. When the travel plan creation unit 112 executes the creation of the travel plan, the ECU 11 detects the detection signals detected by the sensor unit 12, that is, the detection signals detected by the position sensor 121, the travel status sensor 122, the external status sensor 123, and the internal status sensor 124, respectively. Capture the signal (S31).

That is, the position sensor 121 detects the current position of the automobile. The traveling condition sensor 122 detects the traveling condition of the automobile such as the acceleration, the vehicle speed, and the steering direction of the automobile. The external condition sensor 123 detects the conditions and weather around the automobile as the external conditions of the automobile, such as road congestion, road construction, sunny conditions, rain, and snow. The internal status sensor 124 detects the number of passengers of the user and the health condition of the user, whether it is an adult or a child.

Then, the current state recognition unit 111 recognizes the current position recognition unit 111a, the external situation recognition unit 111b, the traveling situation recognition unit 111c, and the user state recognition unit 111d based on the detection signal of the sensor unit 12 (S32). The current position recognition unit 111a recognizes the current position of the automobile. The external situational awareness unit 111b recognizes the surrounding road conditions in which the automobile is currently traveling, such as an urban area or a suburb, and further recognizes the weather, temperature, and the like. The travel situational awareness unit 111c recognizes the current vehicle speed of the vehicle and the travel time since the vehicle started traveling. It also recognizes road congestion. The user state recognition unit 111d recognizes the user's occupant composition, the user's health state, mood, and the like.

Then, the travel plan creation unit 112 creates a candidate for a travel destination to be proposed based on each recognition by the current status recognition unit 111 (S33). The creation of the travel destination candidate is based on an arbitrary algorithm, and for example, processing by AI (artificial intelligence) is adopted. Here, it is created as follows.

The current position recognition unit 111a recognizes the current position of the automobile and also recognizes the current time. If the current time is in the afternoon, a travel destination at a nearby distance is selected as a candidate, and if it is in the morning, a travel destination at a farther distance is selected as a candidate. Further, the traveling situational awareness unit 111b recognizes the vehicle speed of the vehicle and the traveling time from the first time of traveling, and when the vehicle speed is low or the traveling time is long, a nearby traveling destination is selected as a candidate. When the vehicle speed is high or the running time is short, a distant destination is selected as a candidate. These candidates are geographical candidate elements.

The external situational awareness unit 111c recognizes the weather and temperature around the automobile, and when it is raining or cold, the destination with indoor facilities is selected as a candidate, and when the weather is fine, the destination including outdoor facilities is selected as a candidate. These candidates are external candidate elements.

The user state recognition unit 111d recognizes the personnel composition of the user, and if a child is included, a travel destination having a child facility is selected as a candidate. In the case of elderly people, a destination with a rest facility is a candidate. In addition, the health condition is recognized from the user's facial expression and voice, as well as the heart rate, respiratory rate, and breath sounds, and when the user's health condition is recognized as not necessarily good, a travel destination for emphasizing health is selected as a candidate. These candidates are human candidate elements.

Then, the travel planning unit 112 compares these geographical candidate elements, external candidate elements, and human candidate elements with a plurality of travel destinations stored in the database unit 13, and selects each candidate element. Select the destination to meet (S34). Then, the map information and the area information related to the selected plurality of travel destinations are read from the database unit 13, and the travel plan is created by combining these with the corresponding travel destinations (S35). At this time, the user's unique information stored in the user data unit 133 may be referred to, and the area information of the travel destination visited by the user in the past may be combined.

In addition, the database unit 13 may store a combination of the travel destination, each map information, and the area information. Further, the regional information may be updated through the communication control unit 141.

In this way, the travel plan created by the travel plan creation unit 112 comprehensively considers the situation of the automobile, the external situation, the situation of the user, and the like. Therefore, the proposed travel destination and the travel plan of the current automobile. It will be favorable for the situation and the situation of the user. Therefore, the user can drive to a destination that is satisfactory to the user simply by selecting the proposed travel plan or driving according to the proposal determined by the device.

Although the travel plan proposal device of the above embodiment has been described in the case of being applied to a vehicle driven by the user himself / herself, the travel plan proposal device may be equipped in the autonomous driving vehicle. In this case, the user only determines the proposed travel plan, or by entrusting it to the travel plan proposal device, the vehicle automatically moves to the preferred travel destination, so that the user does nothing and prefers the travel. It will be possible to visit the destination.

In the embodiment, an example in which the travel plan proposal device is integrally configured with the navigation system has been described, but the device may be configured as a device independent of the navigation system. Alternatively, any one or more of the sensor unit, the input unit, and the output unit may be configured to be used as the navigation system.

Further, the communication control unit may be used to connect a mobile wireless terminal such as a smartphone or tablet to the ECU via an Internet network, a wireless telephone network, or Bluetooth. For example, a smartphone is attached to the dashboard of an automobile, and the smartphone is configured as an input unit of an ECU for user setting and input, or the display surface of the smartphone is configured as an output unit of an ECU to display a travel destination. You may. Further, the smartphone may be connected to the navigation system of the automobile wirelessly or by wire so that the smartphone has an ECU function.
