Abstract: A parameter estimation device using a filter includes a preprocessing computing circuit, a state estimating circuit and a state-of-charge estimating circuit. A low-pass filter of the preprocessing computing circuit transfers the voltage preprocessing value and the current preprocessing value from inputted discharge-and-charge current value and terminal voltage value, respectively. The state estimating circuit estimates parameters of a state equation of a battery equivalent model based on the battery equivalent model containing a resistance and a capacitor from the voltage preprocessing value and the current preprocessing value inputted. The state-of-charge estimating circuit estimates the state of charge from state quantity obtained. The time constant varies in such a way that the higher the temperature and the state of charge becomes the smaller the time constant becomes.

Light that is emitted from a light source, and enters from an incident portion of a light guide member (light guide body) made of a translucent member formed along an outer edge portion of a decorated portion, travels in the light guide portion while repeating total reflection by an inner surface of the light guide member. In the light-guiding portion, the light is guided in the decorated portion made of a translucent member from the inside of the light guide member, and is emitted outside by being scattered by the inside of the decorated portion, and in the non-light-guiding portion, the light that travels in the light guide member is prevented from traveling in the decorated portion.

Abstract: A drive circuit for a semiconductor switching element includes an overcurrent protection circuit, a short-circuit protection circuit, and a determination time changing circuit. The overcurrent protection circuit judges that a principal current become an overcurrent when a sense voltage proportional to magnitude of the principal current excesses over a first threshold value, and then reduces the principal current. The short-circuit protection circuit reduces a gate voltage of the semiconductor switching element more quickly than the reduction of the principal current by the overcurrent protection circuit when the principal current becomes a greater overcurrent. The determination time changing circuit makes a determination time needed for determining whether or not to operate the overcurrent protection circuit longer when the magnitude of the principal current gets smaller based on a comparison result between the judgement result of the overcurrent protection circuit and a second threshold value.
