Patent ID: 7248997

Claim:
A driver's condition detector for a vehicle comprising: a first driver's condition detection device for detecting a first life information indicating a driver's degree of activity; a vehicle activity detection device for detecting a first vehicle information indication a vehicle's degree of action; a driver's condition classification device for classifying a two-dimensional map into at least three regions, the two-dimensional map having a first axis representing the first life information and a second axis representing the first vehicle information; a driver's condition determination device for determining whether a driver's condition is suitable for a driving operation based on a distribution of the first life information in the regions; a second driver's condition detection device for detecting a second life information indicating the driver's degree of activity other than the first life information; and a second vehicle activity detection device for detecting a second vehicle information indicating the vehicle's degree of action other than the first vehicle information, wherein: the driver's condition classification device determines a life information threshold based on at least one of the second life information and the second vehicle information and classifies the first life information by the life information threshold; at least one of the second driver's information and the second vehicle information includes a plurality kinds of information classes; and the driver's condition classification device determines the life information threshold based on the plurality kinds of information classes respectively weighted.
