PROBLEM TO BE SOLVED: To provide an electric vehicle brake control method and an electric vehicle brake control device by which in the case that control for applying a regenerative brake force to a motor in 1 pedal model is performed, discomfort in association with said control is suppressed.SOLUTION: An electric vehicle brake control method in which any one of an accelerator mode and 1 pedal mode can be selected, and when a drive wheel slips at the time of regenerative brake of an electric vehicle, the regenerative brake force is reduced in the case that a slip ratio S of the drive wheel is larger than a first specified value, and the regenerative brake force is increased in the case that the slip ratio is smaller than a second specified value which is smaller than the first specified value. According to this brake control method, when the slip ratio becomes smaller than the second specified value after the ratio has become larger than the first specified value thereby increasing the regenerative brake force, an increase speed of the regenerative brake force in 1 pedal mode is so made as to be smaller than an increase speed in an accelerator model.SELECTED DRAWING: Figure 5

    【課題】1ペダルモードにおいてモータに回生制動力を付与する制御を行う場合において、当該制御に伴う違和感を抑制する電動車両の制動制御方法、及び電動車両の制御装置を提供する。【解決手段】本発明に係る電動車両の制動制御方法は、アクセルモードと、1ペダルモードといずれかが選択可能とされ、電動車両の回生制動時、駆動輪がスリップした際、駆動輪のスリップ率Sが第1所定値よりも大きい場合には回生制動力を減少させ、スリップ率が第1所定値よりも小さい第2所定値よりも小さい場合には回生制動力を増加させる電動車両の制動制御方法である。この制動制御方法は、スリップ率が第1所定値よりも大きくなった後、第2所定値よりも小さくなり、回生制動力を増加させる際、1ペダルモードにおける回生制動力の増加速度を、アクセルモードにおける増加速度よりも小さくすることを特徴とする。【選択図】図5
