Title:
電子制御装置
Document Type and Number:
Japanese Patent JP5855167
Kind Code:
B2
Abstract:
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.
