Description

The in-vehicle control device 7 serving as a control unit includes a GPS function unit 40 serving as a position detection function unit, wet low-μ road information 41, a driver side communication unit 42, a network communication unit 43, a warning generation unit 44, and CAN signal transmission / reception. Part 45 is included. The GPS function unit 40 detects the vehicle position for use in route guidance (navigation) or the like by the global positioning system (GPS). The wet low μ road information 41 includes a map including position information of wet low μ roads represented by manholes. The driver side communication unit 42 is a warning output device including a speaker 23, a head mounted display 25, a head up display 5 , a meter indicator 39, a haptic device H, and the like via wireless communication such as Bluetooth (registered trademark) or CAN communication. A drive signal for W is output. The haptic device H can include a vibrator 46 provided on the handle grips 31 and 35, a vibrator under the seat, a rotational friction adjusting device for a throttle grip, a reaction force generating device, or the like.

The wet road information 51 includes wet road information 52 acquired by other vehicles and wet road information 53 acquired from the infrastructure. The wet road information 52 acquired by another vehicle is uploaded to the system server 50 from another vehicle having a rain sensor and a wireless communication device, and the wet road information 53 acquired from the infrastructure is distributed to weather forecast information and various places. Information on the installed rain sensor (rain gauge) is uploaded to the system server 50. The in-vehicle control device 7 can recognize whether or not the road surface around the vehicle is wet based on the wet road information. In addition, wet road information is not limited to rainfall, but may include various information that causes the road surface to get wet, such as snow and hail, dew, running road sweepers, running water from water pipes and rivers, etc. it can. In addition, wet road information includes the time it takes for the road surface to dry after the rain stops, the current rainfall conditions posted by passengers of other vehicles, when there is residual snow or freezing even in fine weather, or when antifreezing agents are sprayed Etc. can be considered.

The server-side wet low-μ road information 55 is updated with the latest information on wet low-μ roads such as new manholes and iron plates. Car Nosei control device 7 periodically to the system server 50 (e.g., once daily) By accessing, updating the wet during low μ road information 41 stored in the vehicle Nosei control apparatus 7 Can do. In the present embodiment, since the notification of the occupant using a wet during low μ road information 41 stored in the vehicle Nosei control device 7 at the time of normal traveling, a method of constant access to the server-side wet during low μ road information 55 Compared to the above, it is possible to increase the processing speed required for notification.
