    摘要： A battery state estimating unit (110) estimates an internal state of a secondary battery according to a battery model equation in every arithmetic cycle, and calculates an SOC based on a result of the estimation. A parameter characteristic map (120) stores a characteristic map based on a result of actual measurement performed in an initial state (in a new state) on a parameter diffusion coefficient (Ds) and a DC resistance (Ra) in the battery model equation. The parameter change rate estimating unit (130) estimates a DC resistance change rate (gr) represented by a ratio of a present DC resistance (Rc) with respect to a new-state parameter value (Ran) by parameter identification based on the battery model equation, using battery data (Tb, Vb and Ib) measured by sensors as well as the new-state parameter value (Ran) of the DC resistance corresponding to the p resent battery state and read from the parameter characteristic map (120).

    摘要： In a detecting apparatus, a resolver generates signals whose magnitudes vary periodically in accordance with a positional change of a fixed element side rotating shaft, which is a base for rotation of a rotator and whose position is offset when force of a component parallel to a rotation plane is applied thereto, and in accordance with a rotational state of the tire. An R/D converter generates pulses whose periods correspond to a rotational angle of the rotator and to positional offset of the rotating shaft. From the pulses, a computer detects a characteristic amount which varies in accordance with the positional offset of the shaft. On the basis of the detected amount and a relationship which is determined in advance on the basis of stiffness of the shaft and the amount, the computer detects a moment applied to the shaft, and computes a force generated at the tire.
