9. The driving maneuver assisting apparatus as claimed in claim 1 , wherein the driving maneuver assisting apparatus further comprises: a judging section configured to detect a current running environment around a vehicle and to judge whether or not the detected current running environment differs from a predetermined standard environment; and a third varying section configured to vary at least one of the threshold value and the non-steady-state degree so as to make it difficult for the non-steady-state degree to exceed the threshold value, when the judging section determines that the current running environment differs from the predetermined standard environment.
1. A driving maneuver assisting apparatus comprising: a learning section configured to learn a driving-behavior pattern of a driver for a predetermined duration; a non-steady-state degree calculating section configured to calculate a non-steady-state degree by comparing a current driving-behavior pattern with the driving-behavior pattern learned by the learning section, wherein the non-steady-state degree represents how different the current driving-behavior pattern is from the driving-behavior pattern learned by the learning section; a learning level calculating section configured to calculate a learning level of the learning section; and a notifying section configured to notify the driver of maneuver assisting information for inducing the driving-behavior pattern learned by the learning section in accordance with the learning level calculated by the learning level calculating section, when the non-steady-state degree calculated by the non-steady-state degree calculating section exceeds a threshold value, wherein the notifying section is configured to provide contents of the maneuver assisting information in more detail as the learning level calculated by the learning level calculating section becomes higher, and wherein the learning level calculating section is configured to calculate the learning level of the learning section in accordance with a number of data points already acquired as the driving-behavior pattern of the driver by the learning section.
