DRIVING EVALUATION METHOD AND RECORDING MEDIUM FOR DRIVING EVALUATION ENCODED WITH A PROGRAM

A driving evaluation method includes acquiring a tire force, calculating a proportion, and calculating an evaluation value. The acquiring of the tire force acquires a tire force generating while a vehicle is running. The calculating of the proportion calculates the proportion value by dividing the tire force acquired by the acquiring of the tire force by a load value. The calculating of the evaluation calculates the evaluation value by integrating the tire force for which the proportion value acquired by the calculating of the proportion value belongs to a range defined by a threshold value.
