Patent Images
1. A method for providing a driving person with helpful information for driving a vehicle comprising the steps of:
- detecting travelling conditions of a vehicle responding to a driving operation of said vehicle by a driver who is driving said vehicle;
obtaining a variation pattern by calculating the rate of change per unit time of a detection signal generated in the preceding detecting step;
computing a normal pattern always representing the latest average driving operation by said driver by sequentially accumulating data of said variation pattern at every predetermined unit of time, while sequentially cancelling the oldest data accumulated,further computing a deviation of said variation pattern from said normal pattern; and
in accordance with the result of the computation in the preceding computing step, generating information giving said driver notice anticipated from the degree of the deviation.

Abstract
There is provided a driver assisting system in which the drivng conditions corresponding to the driving operation of a driver in a vehicle are detected to obtain a variation pattern of the driving conditions according to the variation of the driving conditions with time, and the degree of deviation of the variation pattern from the normal pattern inherent to the driver is computed, whereby information for assisting the driving operation of the driver is generated in accordance with the results of the computation.
