The research of visual behaviors and brains has shown that a beginner or an elderly driver cannot afford to drive his or her vehicle looking around. It is thought that this results in the anxiety for driving or an accident. The AI caution assumption model, first developed by Honda ahead of other companies, notifies a beginner or young driver of the risks predicted, resulting in safe action “by himself or herself” at an earlier stage. Elderly drivers tend to be delayed in responding to the events such as the yawing of a vehicle and a delay in braking, which leads to anxiety for driving or an accident. We have been researching the operation assistance that will guide the drivers so as not to have the yawing problem thanks to the driving action model of the AI by grasping the characteristics of elderly drivers.
