Driver assistance apparatus, driver assistance method, and non-transitory recording medium

A driver assistance method of assisting a driver in driving a vehicle, the driver being a person who drives the vehicle, the driver assistance method comprising:

• acquiring information on a surrounding environment of the vehicle;
• recognizing the surrounding environment based on the information, including recognizing one or more detected objects present around the vehicle;
• calculating a level of trust of the driver in a driver assistance apparatus;
• displaying, in a display area of a display, recognition result information including an image indicating the vehicle and one or more images indicating the one or more detected objects;
• determining that the driver is in a standard trusting state when the trust level is greater than or equal to a predetermined distrust threshold and less than or equal to a predetermined over-trust threshold;
• setting the display area to a first area when the driver is in the standard trusting state, the first area being a display range of the display in which results of measurement in a first predetermined region around the vehicle are displayed;
• determining that the driver is in a distrusting state when the trust level is less than the predetermined distrust threshold, and increase, when the driver is in the distrusting state, a number of information items indicating a state of at least one of the one or more detected objects displayed in the display area;
• and
• determining that the driver is in an over-trusting state when the trust level is greater than the predetermined over-trust threshold, and set, when the driver is in the over-trusting state, the display area to an area different from the first area.

A non-transitory computer readable recording medium containing a computer program to be applied to a driver assistance apparatus, the driver assistance apparatus being configured to assist a driver in driving a vehicle, the driver being a person who drives the vehicle, the computer program causing, when executed by one or more processors, the one or more processors to implement a method, the method comprising:

• acquiring information on a surrounding environment of the vehicle;
• recognizing the surrounding environment based on the information, including recognizing one or more detected objects present around the vehicle;
• calculating a level of trust of the driver in the driver assistance apparatus;
• displaying, in a display area of a display, recognition result information including an image indicating the vehicle and one or more images indicating the one or more detected objects;
• determining that the driver is in a standard trusting state when the trust level is greater than or equal to a predetermined distrust threshold and less than or equal to a predetermined over-trust threshold;
• setting the display area to a first area when the driver is in the standard trusting state, the first area being a display range of the display in which results of measurement in a first predetermined region around the vehicle are displayed;
• determining that the driver is in a distrusting state when the trust level is less than the predetermined distrust threshold, and increase, when the driver is in the distrusting state, a number of information items indicating a state of at least one of the one or more detected objects displayed in the display area;
• and
• determining that the driver is in an over-trusting state when the trust level is greater than the predetermined over-trust threshold, and set, when the driver is in the over-trusting state, the display area to an area different from the first area.
