摘要： PROBLEM TO BE SOLVED: To estimate whether or not a driver falls into an inappropriate state in advance and to prevent accidents in future.
SOLUTION: By a lane position sensor 12, time-series data of a lane position signal indicating a distance from a lane center are output. By a distribution parameter estimation part 28, a parameter for determining a probability distribution function indicating a general extremal value distribution is estimated on the basis of the section maximum value of each section extracted from the time-series data of the lane position signal. By a departure probability estimation part 30, a departure probability is estimated from the probability distribution function determined by the estimated parameter, and the departure probability after a predetermined time is predicted on the basis of the tendency of the estimated departure probability by a departure probability prediction part 34. By an inappropriate driving estimation part 36, whether or not the driver falls into an inappropriate state is estimated on the basis of the predicted departure probability.

摘要： PROBLEM TO BE SOLVED: To prevent an accident from occurring caused by overconfidence in a drive intervention system and overconfidence to a driving ability. SOLUTION: In the case of a location where there was an accident, and where drive intervention by the drive intervention system operated, it is judged that the location is the one where there was the accident since the location can not be fully covered even though the drive intervention system operated. In the case of a location where there was an accident, and where the drive intervention by the drive intervention system did not operate, it is judged that the location is the one where there was the accident at the situation that the drive intervention was not performed out of a cover object of the drive intervention system. In the case that a location separated from a location of a self-vehicle at prescribed distance in the traveling direction is the one where there was no accident, and the drive intervention by the drive intervention system operated, it is judged that the location is the one where the occurrence of accident was avoided by being covered by an operation of the drive intervention system. The warning content according to a determination result is output to a driver. COPYRIGHT: (C)2010,JPO&INPIT
