Abstract:
A driving state-monitoring apparatus for an automotive vehicle, for monitoring a driving state of a driver of said automotive vehicle, comprising:behavior parameter-detecting means for detecting a behavior parameter indicative of an amount of behavior related to at least one of yawing movement and lateral movement of said automotive vehicle;vehicle speed-detecting means for detecting a speed of said automotive vehicle;behavior reference parameter-setting means for setting a behavior reference parameter based on changes in said behavior parameter;lateral deviation behavior amount-calculating means for calculating a lateral deviation behavior amount of said automotive vehicle, based on said behavior parameter, said behavior reference parameter, and said speed of said automotive vehicle;driving state-determining means for determining whether or not said driving state of said driver is normal, based on said lateral deviation behavior amount; andabnormality-determining means responsive to at least a determination by said driving state-determining means that said driving state of said driver is not normal, for determining that said driving state of said driver is abnormal.
