A driving assistance method for an autonomous vehicle requests an occupant in the host vehicle to approve passage through an intersection and, upon receiving approval from the occupant, controls the host vehicle to pass through the intersection. The method comprises detecting a situation at an intersection where the host vehicle is approaching; determining whether or not the host vehicle will need to make a temporary stop at the intersection, based on the detected situation at the intersection; and if it is determined that a temporary stop will be needed, delaying the timing to request the occupant to approve passage through the intersection as compared to the timing that would be used if it was determined that a temporary stop would not be needed.

Driving assistance method and driving assistance device

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.

Vehicle traveling assistance method and vehicle traveling assistance device

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.

When making a switch from automated driving to manual driving in a vehicle capable of switching between the manual driving and the automated driving, a driving control method of the present invention makes the switch to the manual driving after changing driving characteristics for the automated driving to switch driving characteristics suitable for the switch to the manual driving.

Driving control method and driving control apparatus

An interest level detection unit configured to detect a level of interest of an occupant in a travel state of an automatic driving vehicle, a manual driving characteristic learning unit configured to learn manual driving characteristics based on the travel state of the automatic driving vehicle, and an automatic driving characteristic setting unit configured to set automatic driving characteristics based on a surrounding state of the automatic driving vehicle, an interest level determination unit configured to determine the occupant's level of interest in the vehicle travel and a driving characteristic setting unit configured to set the driving characteristics based on the manual driving characteristics learned in the manual driving characteristic learning unit when the level of interest is determined to be high and set the automatic driving characteristics set by the automatic driving characteristic setting unit when the level of interest is determined to be low.

Control method and control device of automatic driving vehicle

Provided is a control method of an automatic driving vehicle switchable between manual driving in which the vehicle is made to travel depending on an operation of an occupant and automatic driving in which driving characteristics in automatic travel are set and the vehicle is made to automatically travel based on the driving characteristics. Manual driving characteristics in the manual driving by the occupant are learned and, when switching from the manual driving to the automatic driving is performed, the automatic driving is performed with the manual driving characteristics maintained for a preset manual characteristic maintaining time. As a result, uneasiness of the occupant can be suppressed.
