Method for analyzing the driveability of motor vehicles
First Claim
1. A procedure for analyzing the driveability of motor vehicles, including the following steps:
- Conducting tests on a real vehicle to obtain measurement variables describing its driveability;
Continuous monitoring to check whether one of a number of predefined trigger conditions is fulfilled, i.e., whether a certain set of variables takes on certain values;
If the trigger condition is fulfilled, computation of at least one rating representing vehicle driveability from one or more measured values, using a predefined functional relationship;
Output of the rating;
wherein at least one variable representing the type of driver of the vehicle concerned is derived from the measurement values, and wherein weighting factors are used in computing the rating, which depend on the variable representing the type of driver.

Abstract
This invention relates to a procedure for analyzing and influencing the driveability of motor vehicles, including the following steps:
Conducting tests on a real vehicle to obtain measurement variables describing its driveability;
Continuous monitoring to check whether at least one of a number of predefined trigger conditions is fulfilled, i.e., whether a certain set of variables takes on certain values;
If the trigger condition is fulfilled, computation of a profile of several ratings representing vehicle driveability from one or more measured values, using predefined functional relationships.
An improvement of analysis and control is achieved by deriving from the measurements at least one variable representing the type of driver of the vehicle concerned, and by determining the value of at least one control variable influencing vehicle driveability as a function of the value of the driver-related variable, such that the profile of the several ratings closely approaches a predetermined profile depending on the variable representing the type of driver.
