Driving state monitoring apparatus for vehicles
First Claim
1. A driving state monitoring apparatus for a vehicle, for monitoring a driving state of a driver of said vehicle, comprising:
- behavior parameter detecting means for detecting a behavior parameter indicative of a lateral movement of said vehicle;
vehicle speed detecting means for detecting a vehicle speed of said vehicle;
behavior reference setting means for setting a behavior reference according to changes in the behavior parameter;
running locus calculating means for calculating a running locus of said vehicle according to the behavior parameter, the behavior reference, and the vehicle speed;
vehicle behavior feature parameter calculating means for calculating a plurality of vehicle behavior feature parameters indicative of a feature of vehicle behavior according to the running locus; and
driving state determining means for determining whether or not the driving state of the driver is proper according to the plurality of vehicle behavior feature parameters.

Abstract
A driving state monitoring apparatus for a vehicle, for monitoring a driving state of a vehicle of a driver is disclosed. According to the apparatus, a behavior parameter indicative of a lateral movement of the vehicle and a vehicle speed are detected. A behavior reference is set according to changes in the behavior parameter. A running locus of the vehicle is calculated according to the behavior parameter, the behavior reference, and the vehicle speed. A plurality of vehicle behavior feature parameters indicative of the feature of vehicle behavior is calculated according to the running locus and it is determined whether or not the driving state of the driver is proper according to the plurality of vehicle behavior feature parameters.
