Driving evaluation method and recording medium for driving evaluation encoded with a program

A non-volatile recording medium for real time driving evaluation, the recording medium encoded with a program, the program comprising computer-implemented modules including:

• a tire force acquisition module that acquires a tire force generated in real time, while a vehicle is running;
• an evaluation value calculation module that calculates, in real time, an evaluation value by integrating the tire force acquired by the tire force acquisition module;
• and
• an index value calculation module that calculates, in real time, an index value from the evaluation value calculated by the evaluation value calculation module, based on a predetermined reference value;
• and
• calculate the index value and present the index value on a display, the index value corresponding to values associated with improvements required of the vehicle's tires, and improvements required for a driver's optimal acceleration and braking.
