Abstract
Official abstract text for this publication.
A driving assistance method is for an automated driving vehicle that is capable of switching between manual driving by a driver and automated driving, learns a driving characteristic of the driver during the manual driving, and reflects a learning result to a driving characteristic under control of the automated driving, and the driving assistance method includes: detecting a driving characteristic of an area in which the automated driving vehicle is traveling; and adjusting the learning result according to the detected driving characteristic of the area and executing the control of the automated driving based on the adjusted learning result.
First claim
Opening claim text (preview).
1 . A driving assistance method for an automated driving vehicle that is capable of switching between manual driving by a driver and automated driving, learns a driving characteristic of the driver during the manual driving, and reflects a learning result to a driving characteristic under control of the automated driving, comprising: detecting a driving characteristic of an area in which the automated driving vehicle is traveling; and adjusting the learning result according to the detected driving characteristic of the area and executing the control of the automated driving based on the adjusted learning result. 2 . The driving assistance method according to claim 1 , wherein when a predetermined gap occurs between the driving characteristic of the area and the learning result, the learning result is adjusted to be closer to the driving characteristic of the area. 3 . The driving assistance method according to claim 1 , wherein an acceptable range is set for the driving characteristic of the area, the acceptable range being set based on a driving behavior characteristic of drivers in the area. 4 . The driving assistance method according to claim 3 , wherein the acceptable range is changeable depending on a surrounding situation of the automated driving vehicle. 5 . The driving assistance method according to claim 1 , wherein the driving characteristic to be learned is at least one of an inter-vehicle distance, a timing of braking, a speed, an acceleration, and a gap time. 6 . The driving assistance method according to claim 1 , wherein the area is divided by administrative unit. 7 . The driving assistance method according to claim 1 , wherein the area is divided by region having a similar driving characteristic. 8 . The driving assistance method according to claim 1 , wherein the driving characteristic of the area is stored in the automated driving vehicle in advance. 9 . The driving assistance method according to claim 1 , wherein the driving characteristic of the area is calculated by an external server. 10 . The driving assistance method according to claim 9 , wherein the automated driving vehicle obtains the driving characteristic of the area from the external server through a communication unit. 11 . A driving assistance device for an automated driving vehicle that is capable of switching between manual driving by a driver and control of automated driving, learns a driving characteristic of the driver during the manual driving, and reflects a learning result to a driving characteristic under the control of the automated driving, wherein the driving assistance device detects a driving characteristic of an area in which the automated driving vehicle is traveling, adjusts the learning result according to the detected driving characteristic of the area, and executes the control of the automated driving based on the adjusted learning result
