For example, different types of tire conditions may require different responses.

For example, it has been difficult to specify judgment criteria and relationships between parameters, such as which parameters should be prioritized, which combinations of parameters should be considered, and what values should be determined for the parameters. Further, although it is possible for a skilled operator to respond to tire conditions, it is difficult for a skilled operator to respond to all tires at all times, which is not preferred in practice.
