1. A method for judging the drivability of a vehicle comprising the following steps:
- acquiring drivability-relevant physical data during driving operation of the vehicle;
checking the data for the presence of trigger conditions which indicate the existence of specific driving states;
if a specific driving state exists, calculating at least one local evaluation, which is a judgment of an evaluation criterion relevant for the driving state; and
calculating an overall evaluation for the acquired driving state;
wherein upon repeated occurrence of identical driving states, a correction variable is calculated for the evaluations, which is a function of the differences in the behavior of the vehicle upon identical driving states, and a corrected evaluation is calculated, in which this correction variable is considered.

Abstract
The invention relates to a method for judging the drivability of vehicles having the following steps:
- acquiring drivability-relevant physical data during the driving operation of the vehicle;
- checking the data for the presence of trigger conditions which indicate the existence of specific driving states;
- if a specific driving state exists, calculating at least one local evaluation, which is a judgment of an evaluation criterion relevant for the driving state;
- calculating an overall evaluation for the acquired driving state.
An increase of the precision may be achieved in that upon repeated occurrence of identical driving states, a correction variable is calculated for the evaluations, which is a function of the differences in the behavior of the vehicle upon identical driving states, and a corrected evaluation is calculated in which this correction variable is taken into consideration.

16. A device for judging the drivability of vehicles, comprising:
-
a data acquisition unit for acquiring drivability-relevant physical data during the driving operation of the vehicle; a calculation unit for checking the data for the existence of trigger conditions, which indicate the existence of specific driving states, and for calculating at least one local evaluation, which is a judgment of an evaluation criterion relevant for the driving state, and also calculating an overall evaluation for the acquired driving state, and an output unit for displaying physical data and evaluations, wherein the calculation unit upon repeated occurrence of identical driving states of calculates a correction variable for the evaluations, which is a function of the differences in the behavior of the vehicle upon the identical driving states, and further calculates a corrected evaluation in which this correction variable is considered. - View Dependent Claims (13, 14, 15)
