To provide an electrically-driven walking assisting vehicle capable of giving stable assistance according to situations with a simple configuration.SOLUTION: An electrically-driven walking assisting vehicle (1) includes: a vehicle body (2); right and left driving wheels (4R and 4L); right and left motors (40R and 40L) capable of transmitting power to the right and left driving wheels individually; a free-rolling wheel (5); a grip part (3) provided in the upper part of the vehicle body so that a user can grip it while walking in a standing posture; a grip sensor (30) for detecting gripping of the grip part by the user; right and left rotation speed sensors (43) for detecting rotation speeds of the right and left driving wheels individually; and a control part (10) for controlling the right and left motors. Torque is generated to the right and left motors according to a torque map for stipulating relationships between the rotation speed of the right and left driving wheels detected by the right and left rotation speed sensors and torque command values of the right and left motors in a state that the gripping is detected by the grip sensor.SELECTED DRAWING: Figure 2

    【課題】 簡素な構成により状況に応じて安定的なアシストを行える電動歩行補助車を提供する。【解決手段】 電動歩行補助車(1)は、車体(2)、左右駆動輪(4L,4R)、前記左右駆動輪に個別に動力伝達可能な左右モータ(40L,40R)、自在輪(5)、前記車体の上部に利用者が起立歩行姿勢で把持できるように設けられた把持部(3)、前記把持部の利用者による把持を検知する把持センサ(30)、前記左右駆動輪の回転速度を個別に検知する左右回転速度センサ(43)、および、前記左右モータを制御する制御部(10)を備え、前記把持センサが把持を検知している状態で、前記左右回転速度センサに検知される前記左右駆動輪の回転速度と、前記左右モータのトルク指令値との関係を規定するトルクマップに従って、前記左右モータにトルクを発生させるように構成されている。【選択図】図2
