It is also preferable that the in-vehicle device 200 transmits the destination to the traffic information center 300, the traffic information center 300 calculates an optimum route to the destination, and provides the calculated route to the in-vehicle device 200.

In such a device, when a route search to a destination near station C is performed on a road near station A as shown in FIG. 4, the following route calculation is performed, and a plurality of recommended routes are calculated. Is calculated and displayed.

That is, walking from the current location to the destination and using public transportation (stations A to B or stations A to C)
(Station), a taxi from the B station or C station to the destination or a route such as walking. In particular, when changing to a taxi from a public transportation station, the travel time is estimated by taking into account the traffic information of the taxi use course. As described above, the calculation is performed for a combination of a plurality of types of routes.

Then, the apparatus according to the present embodiment calculates calorie consumption. That is, for a walking section, calorie consumption when walking at a predetermined speed (or a plurality of speeds) is calculated from map data such as a distance and a height difference (including stairs). In this way, for example, two routes A and B as shown in FIG. 5 are calculated as recommended routes and displayed. In the figure, the waiting time and the like are not considered, but actually the waiting time according to the train schedule and the waiting time of the taxi according to the information acquired by communication or the like are also considered.

As described above, the calorie consumption is displayed for the walking section. Therefore, the user can determine whether or not the amount of exercise on the day is sufficient by looking at the consumed calories.

Further, when a target calorie consumption is input, a search for a recommended route that results in a corresponding calorie consumption is performed. For example, as calorie consumption, 1
When the user inputs 000 kcal, as shown in route C in FIG.
A path that is 500 m closer and walks 500 m is displayed as a recommended path. In this way, a desired calorie consumption route can be selected.

Further, the target calorie consumption can be automatically calculated. That is, the apparatus of the present embodiment has the health management database 32c, and the calorie expenditure of the movement by walking is automatically calculated and stored here. Therefore,
The target calorie consumption may be automatically set from the state of the calorie consumption on the day.

Next, route guidance when the above-described route B is set as a route will be described. First, when a route is set, a walking route from the current location to Station A is displayed. That is, a map around the current location is displayed on the display unit 42, the current location is displayed on the map, and the set route is displayed separately from other roads (for example, displayed in a different color from the other roads). Since the current position is changed with the movement of the user, it can be confirmed that the user is walking on the route by the position of the current position display.

Further, in this walking, 500 kca
The consumption of l is the target, for which a walking pace guide flows from the earphone 46. That is, the walking pace is guided by a voice such as "Please walk at this pace." If the actual walking pace is slower or faster than the target, this is notified by display or voice. In this case, the pace of walking is determined in consideration of the departure time of the train to be used at Station A.

When the user arrives at the station A, the calorie consumed by moving to the station is calculated, stored in the health management database 32c and displayed. In addition, as a guide for actions at the station, a train fee, a departure time, a platform number, and the like are displayed and output as audio.

Further, in this example, the route B, that is, the route via the station C is initially set. However, by using FM multiplex broadcasting or communication, traffic congestion on the road from the station C to the destination is recognized, and when it is determined that the route via the station B is more appropriate, the user is notified of this. For example, on a train, a guide such as "There is traffic congestion via Station C. Please take a taxi at Station B."

If the user is at station B, guidance is given on actions such as "Climb the west exit stairs. There is a taxi stand." If it is determined that walking exercise is preferable on the way to the destination by taking a taxi, it is recommended that "20 minutes allowance was reached in the arrival time. It is recommended to walk 1 km from here." Is output. When the user walks in accordance with this, the walking pace is guided as in the case described above.

When arriving at the destination, the calories consumed in this direction are calculated, stored in the calorie database, and the message "I arrived at the destination.
I consumed 500kcal for my current trip. Today, we consume 1000 kcal. And the like.

As described above, the health management database 32c
Has stored calorie consumption and has a calorie calculation function. Therefore, when the user carries the device and moves, the calorie consumption can be automatically integrated and output. Further, route search and guidance can be performed in consideration of calorie consumption.

When the present apparatus is brought into a vehicle, data such as calorie consumption is supplied to the on-vehicle device 200 by the communication device 28. Therefore, even when a route search is performed using the on-vehicle device 200, a route search in consideration of health conditions can be performed. For example, when an exercise is recommended due to health conditions, the vehicle is guided not to the parking lot P1 near the destination (station) as shown in FIG. 6 but to a parking lot P2 relatively far from the destination, and from there. Find a walking route.

In the database 32, a database for other medical information can be provided.
It is also preferable to perform a route search or route guidance to avoid traveling in a place with bad air, avoid a route (curved road, etc.) that is easily sick, or avoid a route that is easily tanned.

Further, not only the consumed calories but also the display of the number of steps by the output of the pedometer 20 is preferable. At this time, a route search or the like according to the target number of steps can be performed in the same manner as described above. In addition, the calorie consumed in a meal or the like may be input to more precisely manage the target calorie consumption. It is also preferable to provide a heart rate monitor 30 to manage the upper limit of the heart rate, detect a drowsiness during driving from the heart rate, and prevent the drowsiness by outputting a sound. Further, it is also preferable to encourage a regular break during long-time driving.
