Title:
DRIVING STATE MONITORING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3411460
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent erroneous judgement in the beginning of driving start, in which there are a little sample data, by using a prescribed value hard to be judged as abnormality as the initial values of plural driving condition values to be defined as the objects of statistic processing when starting driving a vehicle.
SOLUTION: On the input side of microcomputer 1, a yaw rate sensor 10, car speed sensor 12 and winker switch 11 for detecting the will of lane change for the driver of vehicle are connected. On the output side of microcomputer 1, an alarm part 24 is connected. The statistic processing is performed concerning the plural driving state values detected while deviating a sampling time point and based on this statistic processing result, it is judged whether the driving state of driver is proper or not. As the initial values of plural driving state values to be defined as the object of statistic processing when stating driving the vehicle, the prescribed value hard to be judged as abnormality is used. Afterwards, with the detection of driving condition values, the statistic processing is performed by successively updating the initial values to the detected driving state values.
