To provide a regenerative braking control device for an electric vehicle which can prevent a vehicle behavior from being instable on a low μ road, and prevents discomfort in a change of deceleration feeling on the low μ road and a high μ road.SOLUTION: A regenerative torque control part (102) controls a regenerative torque so as to have a predetermined gradient (ΔTb) at the time of a regenerative start, and reduces the regenerative torque after rising of the regenerative torque compared with the case in which a road surface friction coefficient is large when the road surface friction coefficient acquired by a road surface friction coefficient acquisition part (101) is small.SELECTED DRAWING: Figure 2
【課題】低μ路において車両挙動が不安定になることを抑止し得るとともに、低μ路と高μ路における減速感の変化に違和感を生じ難い、電動車両の回生制動制御装置を提供することを目的とする。【解決手段】回生トルク制御部(102)は、回生開始時に所定の立ち上がり勾配(ΔTb)を有するよう回生トルクを制御し、路面摩擦係数取得部(101)が取得した路面摩擦係数が小さい場合は、路面摩擦係数が大きい場合に比較して、回生トルクの立ち上がり後の回生トルクを小さくするよう構成されている。【選択図】図2
