    摘要： A battery state estimating device being one aspect of the present invention detects a current and a terminal voltage of a secondary battery, estimates a terminal voltage of the secondary battery which is based on a predetermined battery model by using measured values I(k) and V(k) respectively of the detected current and the detected terminal voltage, and sequentially identifies a parameter φ^(k) of the battery model in such a way that the difference between a value based on the measured value of the terminal voltage and an estimate value of the terminal voltage converges to zero. Then, when a certain parameter φn in the identified parameter is equal to or larger than a predetermined first threshold δ1, the battery state estimating device performs upper limit processing of setting the value of the certain parameter φn to the first threshold δ1.

The corrected regenerative braking-torque command value is employed in the control of the regenerative brake apparatus.
