    摘要: An abnormality detection circuit for a resolver outputs a rotation angle signal corresponding to a rotation angle of a rotor from a resolver winding. In the abnormality detection circuit, the resolver abnormality detection circuit applies a specified signal to one terminal of the resolver winding, determines whether the specified signal is superimposed on the rotation angle signal outputted by an other terminal of the resolver winding, and detects abnormalities of the resolver based on results of the determination.

    摘要: An electronic control apparatus includes a control unit 2; a plurality of power supply units 1-1, 1-2 for supplying the control unit 2 with power; and a power supply fault detector unit 3 for detecting a fault in the plurality of power supply units 1-1, 1-2. The control unit 2 operates in a normal mode on electric power supplied from the plurality of power supply units 1-1, 1-2, when none of the plurality of power supply units 1-1, 1-2 is faulty. If at least one of the plurality of power supply units 1-1, 1-2 is faulty, the control unit 2 operates in an energy saving mode in which less power is consumed on electric power supplied from the power supply unit that remains fully operational. Thereby an electronic control apparatus is obtained that enables continued operation during a faulty condition, while preventing circuit scale, dimensions, weight, and cost from increasing.
