  The present invention relates to an in-vehicle system, an in-vehicle device, and a portable terminal device in which a portable terminal device carried by a driver and an in-vehicle device are connected by wireless communication.

  In recent years, as the awareness of health management has increased throughout society, especially among middle-aged men and women who are more concerned about health, they can manage their health by eliminating exercise shortages, More and more people are calculating their calorie consumption from exercise volume), blood pressure, body temperature, body fat, etc. to manage their health.

  As methods for resolving lack of exercise, for example, there are counting the number of walks using an inexpensive pedometer, regular exercise in a gym, and the like. Moreover, as a calculation of calorie consumption, there is a method of calculating by itself from its own blood pressure, body temperature, body fat, exercise amount, etc., but an application capable of calculating calorie consumption is also provided in a mobile communication terminal such as a mobile phone.

  An application that calculates calorie consumption (installable) installed in a mobile communication terminal, etc. calculates the amount of exercise of the user from the vibration of the mobile communication terminal, etc., and the calculated amount of exercise and personal information (age of the registered user) And calorie consumption is calculated from the height and weight.

  Such an application for calculating calorie consumption is not limited to a mobile communication terminal. Recently, a driver's driving operation, an in-vehicle environment (for example, room temperature, etc.), a driving state (for example, continuous driving or driving for a long time). In-vehicle devices have been developed that calculate how many calories were consumed during driving, such as distance.

  Thereafter, the calorie consumption calculation start unit 26b of the in-vehicle device 20 detects that the vehicle has started running based on information obtained from the various sensors 30 and the communication devices 40 (Yes in step S111), the expression (1) ), The calorie consumption during driving is calculated based on the time (exercise time) until the vehicle is parked, the body weight (kg), and the number of METs (for example, 0.5) (step S112).

  And the determination part 26d of the vehicle-mounted apparatus 20 determines whether the sum total of the calorie consumption before driving | running | working and the calorie consumption during driving | running | working reached | attained the target value at predetermined intervals (for example, every 1 hour) (step). S113) When the target value is reached (Yes at Step S113), a screen indicating that the target has been reached is displayed on the display unit 23 (Step S114).

  In addition, the determination unit 26d of the in-vehicle device 20 displays a screen indicating that the target has been reached, and then indicates that the vehicle has finished traveling based on information obtained from the various sensors 30 and the communication devices 40. When detected (Yes at Step S115) or without reaching the target value (No at Step S113), when it is detected that the vehicle has finished traveling (Yes at Step S115), the calorie consumption during driving at the local point The calorie consumption before driving and the target value are displayed on the display unit 23 (step S116). On the other hand, while the vehicle is traveling (No at Step S115), the process returns to Step S112 and the subsequent processing is executed.

  In this way, the calorie consumption calculation end transmission unit 26c of the in-vehicle device 20 that has detected that the vehicle has finished traveling transmits the calorie consumption during driving calculated from the start of driving to the end of driving to the mobile terminal 10. (Step S117 and Step S118), the calorie consumption calculating unit 17a of the mobile terminal 10 adds the calorie consumption during driving to the calorie consumption calculated in the device itself to calculate the total calorie consumption (Step S119). ).

[Effects of Example 1]
As described above, according to the first embodiment, the in-vehicle system 1 accurately calculates the calorie consumption according to the vibration and the movement amount with the mobile terminal 10 except during driving such as walking, and the in-vehicle device 20 during driving. Since calorie consumption due to driving can be accurately calculated, calorie consumption due to driving can be accurately calculated even in a vehicle with a large amount of vibration and a long movement amount. Further, when the holder of the mobile terminal 10 gets into the car, the in-vehicle system 1 transmits information necessary for calculating calorie consumption from the mobile terminal 10 to the in-vehicle device 20 by wireless communication such as Bluetooth (registered trademark). Therefore, the trouble of registering personal information in the in-vehicle device 20 does not occur. As a result, the in-vehicle system 1 can accurately calculate the calorie consumption consumed in daily life without taking time and effort.

  In addition, according to the first embodiment, the portable terminal 10 and the in-vehicle device 20 are established by wireless communication, and the consumed calorie calculation application of the portable terminal 10 is stopped while the in-vehicle device 20 is executing the consumed calorie calculation. Can be put to sleep. Furthermore, not only the stop and sleep states but also degeneration control such as changing the input source to the in-vehicle device 20 can be performed. As a result, malfunctions in the calorie consumption calculation can be prevented, and the power consumption of the mobile terminal 10 can be suppressed.

  Further, according to the first embodiment, the current value of calorie consumption, the remaining number up to the target value, and the like can be displayed on the screen by animation or the like. As a result, the user can accurately recognize the current value of calorie consumption and the value up to the target, and use of animation or the like can improve the user's willingness to further calorie consumption.

  Moreover, in Example 1, although the calculation of the calorie consumption during driving | running | working is performed in the vehicle-mounted apparatus 20, it can also comprise so that the said calculation may be performed with the portable terminal 10. That is, when the mobile terminal 10 and the in-vehicle device 20 are established by wireless communication, the mobile terminal 10 obtains operation information of the in-vehicle device 20 such as a handle and a brake from the in-vehicle device 20 and calculates calorie consumption during driving. You may make it use.
