PROBLEM TO BE SOLVED: To provide a power supply controller for vehicle, capable of operating equipment normally at once, when vehicle speed reaches equipment operation vehicle speed, and improving power saving effect.SOLUTION: The power supply controller for vehicle blocks power supply to pieces of equipment 1a, 1b which are preset from a battery, in a preset vehicle speed range, and when the vehicle speed becomes power supply restoration vehicle speed, power supply to the pieces of equipment 1a, 1b is restarted. The power supply controller for vehicle comprises: a change degree acquisition part 4 for acquiring change degree of vehicle speed; a power supply restoration timing calculation part 4 for calculating power supply restoration timing for operating the pieces of equipment 1a, 1b normally at the constant equipment operation vehicle speed; and power opening/closing parts 4, 3a, 3b for restarting power supply to the pieces of equipment at the power supply restoration timing.
【課題】車速が装備動作車速に達したとき、装備を直ちに通常動作させて、省電力効果を向上させ得る自動車用電源制御装置を提供する。【解決手段】あらかじめ設定された車速範囲で、あらかじめ設定された装備1a,1bへのバッテリーからの電力供給を遮断し、車速が電源復帰車速となったとき装備1a,1bへの電力供給を再開する自動車用電源制御装置において、車速の変化度を取得する変化度取得部4と、変化度に基づいて、装備1a,1bを一定の装備動作車速で通常動作させるための電源復帰タイミングを算出する電源復帰タイミング算出部4と、電源復帰タイミングで装備への電力供給を再開する電力開閉部4,3a,3bを備えた。【選択図】図1
