摘要： A moisture sensor that consumes reduced power is provided, and a steering system with the moisture sensor is also provided. A recessed portion (17c) is formed in an inner wall surface of a lower portion of a reduction gear housing (17b) (a lower wall surface in FIG. 2) in the direction of gravity and between a bearing (44) and an outer wall of the reduction gear housing (17b) (a right side wall in FIG. 2). The recessed portion (17c) is formed to have such a depth that the recessed portion (17c) does not penetrate the reduction gear housing (17b). The recessed portion (17c) is formed in the reduction gear housing (17b) within a given range in a circumferential direction with respect to the axis of a rack shaft (12) serving as the center. A moisture sensor (60) is mounted in the recessed portion (17c) to detect water infiltrating into a housing (17). The moisture sensor (60) has a transmission circuit that operates using a water battery as a power supply source. The water battery generates power when water flows into the water battery.

摘要： There is provided an electric power steering apparatus that detects and stores occurrence of a reverse connection when the reverse connection has occurred, and restricts a power assist at the next startup of a controller. Specifically, in an ECU (14) for controlling an electric motor (13) that applies a steering assist torque on a steering mechanism, a microcomputer (14a) transmits a drive signal to a driver (14b) that drives an inverter (14c), which controls current of the electric motor, in accordance with the drive signal. A reverse connection storage circuit (14d) is attached in parallel with the inverter (14c), and detects and stores the occurrence of the reverse connection when the reverse connection of the ECU (14) and a battery (15) has occurred, and notifies the microcomputer (14a) of the occurrence of the reverse connection at the next startup of the ECU (14). The microcomputer (14a) transmits a signal indicating non-permission to the driver (14b) in accordance with the notification. The driver (14b) restricts the power assist upon receiving the signal.

摘要： A method of mitigating abnormalities in a first control command for controlling a power steering system is provided. The method generates a range signal indicative of a range of command values based on a plurality of input signals. The method determines whether the first control command is out of the range for longer than a predetermined duration of time. The method limits the first control command to the range and sends the limited first control command to the power steering system in response to determining that the first control command is out of the range for shorter than or equal to the duration of time.
