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.

摘要： The present invention is directed to improve reliably of an on-chip redundancy system by preventing influence of a physical failure exerted on an entire semiconductor chip. A comparator measure for comparing outputs of an on-chip redundancy system is mounted on a semiconductor chip different from the on-chip redundancy system. The another semiconductor chip is, preferably, mounted on a semiconductor chip on which a power source circuit for supplying power to the on-chip redundancy system redundantly having the comparing function in the chip, a driver circuit for driving an output circuit, and the like are mounted. With the configuration, the influence of a failure occurring in the on-chip redundancy system can be prevented from being exerted on the comparator measure.

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： The present invention provides an electric power steering controller and an electric power steering system that allow appropriate operation even when the operation of their torque sensors is abnormal.The controller 100 of a main microcomputer 1-1 outputs motor drive signals 3 to a drive circuit 5 based on first and second torque signals detected by a torque sensor 2 that detects steering force. The drive circuit 5 drives a motor 6 to generate assistive torque. A torque sensor abnormality detector 101 is installed within the main microcomputer 1-1 and detects abnormalities of the torque sensor 2 based on the first and second torque signals. An excessive torque detector 102 is installed within an external device 1-2 and outputs a motor stop signal when either of the first and second torque signals exceeds a given value.
