1. A driving assistance device, comprising:
- a traffic situation detector to acquire signal information representing indication schedule of a traffic signal;
a vehicle speed detector to acquire a speed of an own vehicle as information;
a current position detector to acquire a current position of the own vehicle as current positional information;
a travel route generator to acquire, as travel route information, a spot where deceleration is required on a planned travel route along which the own vehicle travels;
a history information storage to store, as history information, the vehicle information correlated to the current positional information;
a travel pattern generator to generate a travel pattern by acquiring a recommended speed when the own vehicle travels along the travel route based on the signal information, the vehicle information, the current positional information, the travel route information, and the history information;
a travel pattern communicator to transmit the travel pattern of the own vehicle generated by the travel pattern generator and receive a travel pattern of a preceding vehicle of the own vehicle by communicating with a server device;
a travel pattern corrector to correct the travel pattern of the own vehicle generated by the travel pattern generator based on the travel pattern of the preceding vehicle received by the travel pattern communicator from the server device; and
an information provider to provide the own vehicle with the travel pattern of the own vehicle generated by the travel pattern generator or corrected by the travel pattern corrector.

Abstract
A travel pattern communication unit 15 receives a low fuel consumption travel pattern of a preceding vehicle of an own vehicle from a server device 200. A travel pattern correction unit 17 corrects a reference travel pattern of the own vehicle generated by a travel pattern generation unit 16 based on the low fuel consumption travel pattern of the preceding vehicle received by the travel pattern communication unit 15.

13. A driving assistance method of a driving assistance device to provide a travel pattern of an own vehicle, comprising:
-
acquiring a recommended speed when the own vehicle travels a travel route and generating a travel pattern; transmitting the generated travel pattern of the own vehicle and receiving a travel pattern of a preceding vehicle of the own vehicle by communicating with a server device; correcting the generated travel pattern of the own vehicle based on the travel pattern of the preceding vehicle received from the server device; and providing the own vehicle with the generated or corrected travel pattern of the own vehicle.
