Claim 4:
5. A travel assistance method to be executed in a travel assistance system including a vehicle and a server which is provided outside the vehicle, comprising:
recognizing an obstruction factor for traveling of the vehicle, by using a camera;
obtaining information of an approaching vehicle from the approaching vehicle that approaches the obstruction factor, by using a first processor of the server;
generating, based on information of the recognized obstruction factor, warning information corresponding to information of a type of the approaching vehicle obtained in the obtaining;
transmitting the warning information to the approaching vehicle; and
giving notification to an occupant of the approaching vehicle and/or controlling traveling of the approaching vehicle based on the warning information, by using a second processor of the approaching vehicle,
wherein the approaching vehicle includes a first approaching vehicle and a second approaching vehicle that is located behind the first approaching vehicle; and
the first processor of the server is further configured to predict an avoidance course of the first approaching vehicle with respect to a first obstruction factor based on information of a type of the first approaching vehicle, the first processor generating first warning information and transmitting the generated first warning information to the first approaching vehicle, and the first processor is further configured to generate second warning information including the first obstruction factor, the predicted avoidance course with respect to the first obstruction factor of the first approaching vehicle as a second obstruction factor, and a message indicating that the first approaching vehicle may avoid the first obstruction factor, and the first processor is further configured to transmit the generated second warning information to the second approaching vehicle,
in a case where the second processor of the second approaching vehicle gives notification to the occupant of the second approaching vehicle, the second processor of the second approaching vehicle displays, based on the transmitted second warning information, an image showing a positional relationship between the first obstruction factor and the first approaching vehicle, the predicted avoidance course of the first approaching vehicle with respect to the first obstruction factor, and the message.
