  • Patent number: 8140241
    Abstract: A driver model with higher precision is created as an evaluation standard for a driving condition in a normal condition. By detecting biometric information of a driver, whether a driver is in a usual condition or not is recognized. Then, data of driving conditions are collected while the driver is driving, and from the driving condition data, a part indicating that the driver operates in a usual condition is extracted to create a driver model. Further, the driver model is created taking only a case of driving in a normal condition as a driving action in normal times based on biometric information of the driver, and hence the driver model becomes more precise and neutral. Further, by using a GMM (Gaussian mixture model) for the driver model, a driver model for each driver can be created easily, and moreover, by calculation to maximize a conditional probability, a driving operation action is easily estimated and outputted.

  • Publication number: 20090234552
    Abstract: A driver model with higher precision is created as an evaluation standard for a driving condition in a normal condition. Further, a driving action is estimated using a driver model which can be created easily and can represent driving characteristics of a driver more precisely. By detecting biometric information of a driver, whether a driver is in a usual condition or not is recognized. Then, data of driving conditions (own vehicle information such as, for example, operation amounts of accelerator, brake, and steering wheel, vehicle speed, inter-vehicle distance, acceleration, and the like) are collected while the driver is driving, and from the driving condition data, a part indicating that the driver operates in a usual condition is extracted to create a driver model. Thus, without making the driver aware, a driver model for normal times can be created automatically.

  • Patent number: 7044742
    Abstract: An emergency reporting apparatus is provided which is capable of easily acquiring passenger information necessary at the time of an emergency report and reporting as deputy for a passenger in the case of an emergency. The emergency reporting apparatus, in a training mode, simulates questions from an emergency rescue facility which will be addressed when an emergency situation occurs, and learns and stores the reply contents and response procedures. From the questions and replies, the emergency reporting apparatus automatically acquires the necessary passenger information. Then, the emergency reporting apparatus reports, as a deputy for the user, the passenger information acquired in the training mode when there is no reaction from the user at the time of an actual emergency.

  • Publication number: 20040225416
    Abstract: An agent apparatus has a system capable of executing, periodically or when a particular condition is satisfied, processing to judge whether or not a condition to autonomously start (automatically present) an agent is satisfied based on scenario data created by a scenario creating apparatus, and automatically presenting the agent when the condition is satisfied. Thus, in the scenario creating apparatus, regardless of whether having knowledge of programming or not, it is possible to create and edit scenario data of an agent which automatically appears and responds when a particular condition is satisfied by having a scenario editor.
