Abstract

A vehicle traveling assistance method in which a braking timing of a vehicle in manual driving is learned and traveling in automatic driving is assisted based on the learned braking timing, includes activating a brake in the automatic driving such that a timing at which a driver senses a braking operation is earlier than the learned braking timing.

First claim

1 .- 4 . (canceled)

5 . A vehicle traveling assistance method in which a braking timing of a vehicle in manual driving is learned and traveling in automatic driving is assisted based on the learned braking timing, the vehicle traveling assistance method comprising:
learning a timing at which a driver of the vehicle terminates an operation of an accelerator pedal as the braking timing of the vehicle in the manual driving; and activating a brake in the automatic driving such that a timing at which the driver senses a braking operation is earlier than the learned braking timing.

6 . The vehicle traveling assistance method according to claim 5 , wherein the higher a vehicle speed is, the earlier a braking timing in the automatic driving is.

7 . A vehicle traveling assistance method of assisting traveling in automatic driving in which a braking timing of a vehicle in manual driving is learned and a brake in the automatic driving is activated such that a timing at which a driver senses a braking operation is earlier than the learned braking timing, the vehicle traveling assistance method comprising
detecting driving sensitivity indicating sensitivity to driving; and setting a braking timing in the automatic driving based on the detected driving sensitivity.

8 . The vehicle traveling assistance method according to claim 7 , wherein the higher the driving sensitivity is, the earlier the braking timing in the automatic driving is.

9 . The vehicle traveling assistance method according to claim 7 , wherein
data variation is detected from data on a driving operation in the manual driving, and the smaller the variation is, the higher the driving sensitivity is determined to be.

10 . The vehicle traveling assistance method according to claim 7 , wherein
a frequency of a pedal operation of at least one of an accelerator pedal or a brake pedal in the manual driving is detected, and the higher the frequency of the pedal operation is, the higher the driving sensitivity is determined to be.

11 . The vehicle traveling assistance method according to claim 7 , wherein
a frequency of acceleration or speed in the manual driving is analyzed, and the more high frequency components there are, the higher the driving sensitivity is determined to be.

12 .- 14 . (canceled)

15 . A vehicle traveling assistance device which includes a manual driving learning circuit configured to learn a braking timing of a vehicle in manual driving and which assists traveling in automatic driving based on the learned braking timing, wherein the manual driving learning circuit is configured to learn a timing at which a driver of the vehicle terminates an operation of an accelerator pedal as the braking timing of the vehicle in the manual driving, and
the vehicle traveling assistance device further comprises a drive control circuit configured to, in the automatic driving, operate a brake such that a timing at which a driver senses a braking operation is earlier than the learned braking timing.
