DRIVING ASSISTANCE DEVICE
First Claim
1. A driving assistance device that learns travel data during a time in which a driver performs driving operations to make a vehicle travel, and performs driving assistance based on a learned result, comprising:
- a storage portion configured to store respectively a vehicle speed and an acceleration and deceleration tendency at a same place-on a travel route, for a plurality of times, during a time in which the driver performs acceleration and deceleration operations;
a learning portion configured to identify a plurality of object vehicle speeds used for learning from the plurality of vehicle speeds at the same place stored in the storage portion based on the acceleration and deceleration tendency, and when a dispersion of the plurality of vehicle speeds identified as object is small, learns the vehicle speed at the same place based on the plurality of vehicle speeds having the small dispersion; and
a driving assistance portion configured to perform driving assistance, based on the vehicle speed learned by the learning portion, when the vehicle travels at a place where the vehicle speed is learned after learning of the learning portion.

Abstract
A driving assistance device including: a storage portion, configured to store a vehicle speed, an acceleration and deceleration tendency at the same place on a travel route respectively for a plurality of times during a time in which a driver performs acceleration and deceleration operations; a learning portion, configured to distinguish a plurality of object vehicle speeds from a plurality of vehicle speeds at the same place stored in the storage portion, and learn the vehicle speeds at the same place based on the plurality of vehicle speeds with small dispersion when the dispersion of the plurality of vehicle speeds identified as object is small; and a driving assistance portion, configured to perform driving assistance based on the vehicle speed learned by the learning portion, when the vehicle travels at a place where the vehicle speed is learned after learning of the learning portion.
