    摘要： An automatic leveling device and automatic leveling method for being able to reduce an error caused by a hysteresis characteristic of an actuator are provided. A control ECU (3) obtains vehicle height values from a front height sensor (1) and a rear height sensor (2), computes a vehicle height difference from the vehicle height values, and a stroke amount to be corrected of an actuator 4 from the vehicle height difference. The control ECU (3) supplies an instruction position signal based on the stroke amount and a hysteresis width such that the instruction position signal projects tentatively alternately out of a hysteresis range plural times in a reverse direction of an immediately preceding value. Therefore, every time the instruction position signal projects tentatively alternately out of the hysteresis range, a motor (4-2) is started up again and stopped when the instruction position signal is finally matched with an actuator position signal.

    摘要： This invention provides an opening-and-closing member control device capable of detecting trapping and avoiding the trapping load from increasing without being influenced by disturbance. In an opening-and-closing control device for determining the presence of trapping of a foreign material at the window of a vehicle based on the comparison result of the motor load and the threshold value, the changing of the threshold value based on a second disturbance detection signal is prohibited if a first disturbance detection signal based on closing of the door is generated before the second disturbance detection signal based on fluctuation of the motor load, and the threshold value is increased for a predetermined time so that determination on the presence of trapping becomes difficult based on the second disturbance detection signal if the second disturbance detection signal is generated before the first disturbance detection signal.

    摘要： There is provided a power supply device superior in safely which does not cause a second accident such as an electric shock even if the power cable is broken by chance. The power supply device provided with a power socket having a plurality of power supply terminals for supplying an alternating current supply with a predetermined voltage is provided with judgment means for judging whether or not breakage of a power supply path to the power socket has occurred based on whether or not electrical potentials of the plurality of power supply terminals each changes periodically to a first predetermined electrical potential and a second predetermined electrical potential lower than the first predetermined electrical potential, and blocking means for blocking power supply to the power socket when the breakage of the power supply path has been judged by the judgment means.

    摘要： Provided is a motor control device capable of suppressing an abrupt change in current offset value, to hold stable steering feeling. A detected current value of a drift current detected in a state where a motor current is regarded as zero is set as a current offset value, and in a motor control device for compensating a detected current value of the motor current by means of the current offset value, a drift current is detected with respect to each predetermined cycle T, and a target offset value is set with respect to each cycle T based on the thus-detected detected current value of the drift current. A correction value K is added to the current offset value when the current offset value is smaller than the target offset value, and the correction value K is subtracted from the current offset value when the current offset value is larger than the target offset value, thereby to correct the current offset value with respect to each cycle T.
