To provide a parking support device and a parking support method which enable learning-type automatic parking even with an electric power steering with weak torque.SOLUTION: A parking support device includes: a storage unit for storing, as a manual parking path, a path of manual parking in which a driver manually parks a vehicle; a safety region setting unit for setting a safety region through which the vehicle can pass on the basis of the manual parking path stored by the storage unit; a path generating unit for generating an automatic parking path on the basis of the safety region set by the safety region setting unit and performance of an electric power steering; and a vehicle control unit for allowing the vehicle to automatically travel on the basis of the automatic parking path. The path generating unit generates a parking path allowing the vehicle to travel within a range of the performance of the electric power steering and allowing the vehicle to pass through inside the safety region.SELECTED DRAWING: Figure 3 【課題】トルクが弱い電動パワーステアリングでも、学習型の自動駐車を可能とする駐車支援装置および駐車支援方法を提供する。【解決手段】駐車支援装置は、運転者が車両を手動で駐車させる手動駐車の経路を手動駐車経路として記憶する記憶部と、記憶部が記憶した手動駐車経路に基づいて、車両が通過可能な安全領域を設定する安全領域設定部と、安全領域設定部が設定した安全領域と、電動パワーステアリングの性能に基づいて自動駐車経路を生成する経路生成部と、自動駐車経路に基づいて、車両を自動走行させる車両制御部と、を備え、経路生成部は、電動パワーステアリングの性能の範囲内で走行可能な駐車経路であり、かつ、車両が安全領域の中を通過する駐車経路を生成する。【選択図】図３
