Vehicle control device, vehicle control method, and storage medium

A vehicle control method performed by an in-vehicle computer mounted in an own-vehicle, the vehicle control method comprising:

• the in-vehicle computer detecting a state of an oncoming vehicle facing the own-vehicle and a state of a road surface in an oncoming lane in which the oncoming vehicle is present based on an image captured by a camera attached to the own-vehicle;
• and
• determining that an outside of a tunnel toward which the own-vehicle is traveling has bad weather in response to detecting that a wiper of the oncoming vehicle is operating and that the road surface of the oncoming lane is wet while the own-vehicle is in the tunnel.

A computer readable non-transitory storage medium storing a program causing an in-vehicle computer mounted in an own-vehicle having an imaging unit configured to image surroundings of the own-vehicle to:

• detect a state of an oncoming vehicle facing the own-vehicle and a state of a road surface in an oncoming lane in which the oncoming vehicle is present based on an image captured by a camera attached to the own-vehicle;
• and
• determine that an outside of a tunnel toward which the own-vehicle is traveling has bad weather in response to detecting that a wiper of the oncoming vehicle is operating and that the road surface of the oncoming lane is wet while the own-vehicle is in the tunnel.
