Driving assistance method, and driving assistance device and driving assistance system using said method

A driving assistance method for a driving assistance device, the driving assistance device to be installed on a first vehicle, the driving assistance device including a processor, the driving assistance method comprising:

• calculating a possibility of a collision between a detected obstacle and the first vehicle;
• controlling automatic driving of the first vehicle based on the possibility of the collision;
• stopping the first vehicle when the possibility of the collision with a second vehicle, in a case of interruption by the first vehicle in front of the second vehicle, is greater than a predetermined value;
• receiving stop-behavior information about the first vehicle;
• outputting inquiry information for inquiring of an occupant of the first vehicle whether the automatic driving of the first vehicle is to be controlled regardless of the possibility of the collision between the second vehicle and the first vehicle is to a display on the first vehicle, when a distance from a point at which the second vehicle is predicted to end intersection of a road to a point where the second vehicle is currently, the road being on which the first vehicle travels, is greater than or equal to a first threshold, and a speed of the second vehicle is less than or equal to a second threshold, in a case that the stop-behavior information about the first vehicle is received;
• receiving a response operation performed by the occupant with respect to the inquiry information of which the occupant is notified by the display;
• determining the response operation corresponds to a response signal for controlling the automatic driving of the first vehicle regardless of the possibility of the collision between the second vehicle;
• and
• controlling, via a first command, the automatic driving of the first vehicle regardless of the possibility of the collision between the second vehicle and the first vehicle when the response operation corresponding to the response signal is received.

A driving assistance system, to be installed on a first vehicle, the driving assistance system comprising:

• a processor that calculates a possibility of a collision between a detected obstacle and the first vehicle, controls automatic driving of the first vehicle based on the possibility of the collision, and stops the first vehicle when the possibility of the collision with a second vehicle, in a case of interruption by the first vehicle in front of the second vehicle, is greater than a predetermined value;
• a first input that receives stop-behavior information about the first vehicle;
• a display that outputs inquiry information for inquiring of an occupant of the first vehicle whether the automatic driving of the first vehicle is to be controlled regardless of the possibility of the collision between the second vehicle and the first vehicle, when a distance from a point at which the second vehicle is predicted to end intersection of a road to a point where the second vehicle is currently, the road being on which the first vehicle travels, is greater than or equal to a first threshold, and a speed of the second vehicle is less than or equal to a second threshold, in a case that the stop-behavior information about the first vehicle is received;
• a second input that receives a response operation performed by the occupant with respect to the inquiry information of output by the display;
• the processor that determines the response operation corresponds to a response signal for controlling the automatic driving of the first vehicle regardless of the possibility of the collision between the second vehicle and the first vehicle;
• and
• the processor that controls, via a first command, the automatic driving of the first vehicle regardless of the possibility of the collision between the second vehicle and the first vehicle when the response operation corresponding to the response signal is received.
