TIRE STATE ESTIMATION DEVICE AND TIRE

摘要

It is possible to provide a tire state estimation device capable of estimating a tire road holding state in the same level as the conventional way while simplifying sensor wiring in a tire and a tire used for it. A tire used for the tire state estimation device has a plurality of action force sensors in itself and the action force sensors in the tire are connected in series by a signal transfer line for transmitting detection signals in time series to a tire state estimation unit provided in a vehicle. The transmitted detection values continuous in time series are separated for each of the action force sensors by a signal identification unit. An estimation unit handles detection signals identified for each of the action force sensors as detection signals of the tire width direction acquired at the same timing and acquires the road holding length of the tire width direction, thereby estimating the tire road holding state.
