As shown in FIG. 2, the in-vehicle terminal 3 includes a control unit (ECU: Electronic Control Unit) 30, a GPS receiver 31, a gyro sensor 32, a wheel rotation speed sensor 33, a storage unit 34, a display 35, a speaker 36, and an input device. 37, a crosswind detection sensor 38, a vehicle-mounted communication unit 39, and the like.

The control unit 30 performs a route search for the vehicle 2 and controls other electronic devices 31 to 39.
The in-vehicle communication unit 39 includes a wireless communication device having an amplifier circuit, a frequency conversion circuit, a modulation and demodulation circuit, and the like, which are necessary for wireless communication with a base station (not shown) connected to the public communication network 7.

The GPS receiver 31, the gyro sensor 32, and the wheel rotation speed sensor 33 are sensors for measuring the current position, direction, and speed of the vehicle 2.
The control unit 30 obtains the vehicle position of the own vehicle from the GPS signals periodically acquired by the GPS receiver 31. The control unit 30 complements the vehicle position and direction based on the input signals of the gyro sensor 32 and the wheel rotation speed sensor 33, and grasps the accurate current position and direction of the vehicle 2. The output signal of the wheel rotation speed sensor 33 is also used for ABS (Antilock Brake System) control.

  The storage unit 34 includes a map database. The map database provides the control unit 30 with road map data. The road map data includes link data and node data, and is stored in a recording medium such as a DVD, a CD-ROM, a memory card, or an HDD.

It can execute various navigation functions such as a function to perform.

The wheel rotation speed sensor 33 is a sensor that detects the rotation speed of the wheel. The wheel rotation speed sensor 33 detects the rotation speed of the wheel every predetermined time (for example, every several seconds).
The wheel rotation speed sensor 33 generates a rotation pulse using an electromagnetic pickup or the like and measures the rotation speed of the wheel from the number of pulses. Angular velocity sensors including those that measure the rotational speed of the wheel from the vehicle can be used.

Each time the wheel rotation speed sensor 33 detects the rotation speed of the wheel, the control unit 30 calculates the friction coefficient between the road surface and the tire using a known analysis method based on the detected rotation speed. The control unit 30 causes the output device, such as the display 35, to output an alert to the occupant driving the vehicle based on the calculated coefficient of friction.
For example, when the coefficient of friction is equal to or less than the threshold, the control unit 30 causes the display 35 to output a reminder to reduce the vehicle speed because the tire is likely to slip.

The crosswind detection sensor 38 is a sensor that detects a crosswind on the vehicle 2. The crosswind detection sensor 38 detects a crosswind every predetermined time (for example, several seconds).

  Each time the wheel rotation speed sensor 33 detects the rotation speed of the wheel, the control unit 30 uses the information indicating the friction coefficient calculated as described above as weather-related information including an actual measurement value regarding a weather condition around the vehicle 2. Generate. Further, each time the wheel rotation speed sensor 33 detects the rotation speed of the wheel, the control unit 30 transmits information indicating the vehicle position measured by the GPS receiver 31 or the like at the time of detection of the wheel rotation speed sensor 33 to the vehicle 2. Is generated as the position information.

  Each time the crosswind detection sensor 38 detects a crosswind, the control unit 30 generates information indicating the strength of the crosswind calculated as described above as weather-related information including an actually measured value related to a weather condition around the vehicle 2. Further, every time the crosswind detection sensor 38 detects a crosswind, the control unit 30 generates information indicating the vehicle position measured by the GPS receiver 31 or the like as the position information of the vehicle 2 when the crosswind detection sensor 38 detects the crosswind. I do.

The control unit 30 generates unique information indicating a unique condition of the vehicle 2. The unique condition of the vehicle 2 is a unique condition of the vehicle 2 that affects an actual measurement value regarding a weather condition around the vehicle 2.
For example, when the actual measurement value is a coefficient of friction between a road surface and a tire, the specific conditions of the vehicle 2 include a load applied to each tire due to the weight of the vehicle 2, a type of the tire, a degree of wear of the tire, and a drive of a wheel. System. When the measured value is the intensity of the crosswind, the specific conditions of the vehicle 2 include the height of the center of gravity of the vehicle 2 and the area of the vehicle 2 that receives the crosswind.

I do.
Further, when the measured value is the intensity of the crosswind, the control unit 30 of the present embodiment generates unique information including information indicating the height of the center of gravity of the vehicle 2 as a unique condition of the vehicle 2.

The control unit 30 causes the in-vehicle communication unit 39 to transmit the generated weather-related information (information indicating the friction coefficient and information indicating the intensity of the cross wind), the unique information, and the position information.
Therefore, the in-vehicle communication unit 39 of the first in-vehicle terminal 3A transmits the weather-related information of the first vehicle 2A, the first unique information that is the unique condition of the first vehicle 2A, and the position information of the first vehicle 2A to the outside. Functions as a first vehicle-mounted communication unit. The in-vehicle communication unit 39 of the second in-vehicle terminal 3B functions as a second in-vehicle communication unit that transmits second unique information, which is a unique condition of the second vehicle 2B, to the outside.

  The control unit 30 according to the present embodiment causes the information providing device 6 to transmit the weather-related information, the unique information, and the position information through the in-vehicle communication unit 39. However, the control unit 30 of the second in-vehicle terminal 3B includes at least the unique information. (Second unique information) may be transmitted to the information providing device 6 by the in-vehicle communication unit 39.

  In the present embodiment, the friction coefficient between the road surface and the tires and the strength of the cross wind with respect to the vehicle 2 are used as the actually measured values related to the weather conditions around the vehicle 2, but only one of the friction coefficient and the strength of the cross wind is used. May be used as the actual measurement value. Further, as the actual measurement value, any value other than the friction coefficient and the strength of the cross wind may be used as long as the actual measurement value is actually measured with respect to the weather condition around the vehicle 2. For example, since the field of view in front of the vehicle is affected by weather conditions such as fog and rain, a value obtained by actually measuring the degree of the field of view may be used as the actually measured value.
