Title:
センサ装置及び電動パワーステアリング装置
Document Type and Number:
Japanese Patent JP7459693
Kind Code:
B2
Abstract:
To provide a sensor device capable of continuously outputting a physical amount to be detected even when any failure occurs in a sensor and suppressing failures of other components.SOLUTION: An arithmetic logical unit 50 outputs an operation value Ts of a steering torque based on an output signal of a torque sensor which has been determined to be normal. A power supply unit 49 stops power supply to a torque sensor which has been determined to be a failure, and continues power supply to a torque sensor which has been determined to be normal. In addition, a failure determination unit 48 stops failure determination of a torque sensor which has been determined to be a failure, and continues failure determination of a torque sensor which has been determined to be normal.SELECTED DRAWING: Figure 3
