PROBLEM TO BE SOLVED: To prevent a sense of incompatibility from being given to a driver or the like in a sweep operation of a gauge.SOLUTION: A drive controller for a vehicular gauge 10 is capable of executing a sweep operation in which a pointer 13 that is provided on a rotary shaft 14 and points any position from a zero position 11 to a maximum scale position 12, is swept from the zero position 11 to the maximum scale position 12 and then returned to the zero position 11 by driving a stepping motor that rotates the pointer 13, in the vehicular gauge 10 including the pointer 13 that is provided on the rotary shaft 14. The drive controller outputs a rating torque signal to the stepping motor during the sweep operation, performs acceleration to a predetermined speed, then outputs a decremental torque signal that is smaller than the rating torque signal, to the stepping motor and performs rotational drive at the predetermined speed.SELECTED DRAWING: Figure 1
【課題】計器のスイ—プ動作において、運転者などに違和感を与えない。【解決手段】車両用計器10の駆動制御装置は、回転軸14に設けられて零位置11から最大目盛位置12までのいずれかを指し示す指針13を備えた車両用計器10にて、この指針13を回転させるステッピングモータを駆動して、この回転軸14に設けた指針13を零位置11から最大目盛位置12まで振らせた後に、零位置11に再び戻すスイープ動作を実行可能である。駆動制御装置は、スイープ動作において、定格トルク信号をステッピングモータに出力して所定速度まで加速させたのち、定格トルク信号より小さい減トルク信号をステッピングモータに出力して所定速度で回転駆動する。【選択図】図1
