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.

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： A small-sized and low-cost phase detection circuit which has improved noise immunity. The phase detection circuit comprises a multiplier for multiplying an input signal by a reference signal and outputting a first signal, an integration circuit for integrating the first signal and outputting a second signal, a phase estimation circuit for estimating phase information based on the second signal, and a reference signal generation circuit for generating the reference signal based on the estimated phase information. Since the phase is detected based on information representing an entire waveform, the influence of local noise can be diluted and noise immunity can be improved.
