METHOD AND SYSTEM FOR EVALUATING DRIVING CONDITIONS OF A VEHICLE
First Claim
1. A method of evaluating driving conditions of a vehicle whereby drivability of the vehicle driven by a driver under different driving conditions is evaluated, comprising:
- a step of measuring biological information on a driving driver and movement information of the vehicle being driven as driving load information, and acquiring a group of representative values, which is obtained from a measurement result of such information, for each driving condition,a step of selecting a group of weighting coefficients in a number equal to or less than a number of pieces of the driving load information from groups of weighting coefficients that are set according to representative values of the driving load information for each driving condition, anda step of obtaining a weighted linear sum using a selected group of the weighting coefficients and using the weighted linear sum to perform an integrated evaluation of the drivability under each driving condition.

Abstract
The method and system evaluate driving conditions of a vehicle whereby drivability of the vehicle can be evaluated accurately and objectively. To evaluate drivability of the vehicle under different driving conditions, a plural pieces of driving load information including biological information on a driver and movement information of the vehicle being driven are measured. Then, a group of weighting coefficients as many as or fewer than pieces of the driving load information is selected from groups of weighting coefficients that are set according to representative values of the driving load information in order to use a weighted linear sum of the representative values of the driving load information as an index of an integrated evaluation of the drivability of the vehicle. Subsequently, a weighted linear sum is obtained using the selected group of weighting coefficients and used to perform the integrated evaluation of the drivability under various driving conditions.
