A processing server detects an incident of a vehicle by analyzing one of position information about the vehicle, image information about the periphery of the vehicle, and traveling data about the vehicle, which are acquired from the vehicle, and selects a new function corresponding to the detected incident. Then, the processing server gives notice of the proposal for the new function to the vehicle, as an estimated timing when a user having encountered the incident has cooled down while the user's memory about the incident is clear.

Driving assist system

A controllerturns on a semiconductor switchin a normal mode, and turns off the semiconductor switchin a sleep mode. A bypass resistoris connected in parallel to the semiconductor switch. A resistance value of the bypass resisteris so large as that in the sleep mode, a dark current is supplied to an electronic devicevia the bypass resistor, and if an electric wire downstream of the bypass resistor is short-circuited, an electric current more than a permissive current is prevented from flowing to the electric wire.
