PROBLEM TO BE SOLVED: To provide a regenerative cooperation braking device which can appropriately set brake force of at least a driving wheel regardless of car weight.SOLUTION: A regenerative cooperation braking device is applicable to an electric propulsion vehicle comprising: a regenerative motor mechanically connected to a driving wheel; and a first friction brake for the driving wheel. The regenerative cooperation braking device comprises: a first derivation unit which derives brake force of the driving wheel; and a second derivation unit which derives a regenerative brake force of the regenerative motor and a friction brake force of the first friction brake on the basis of the brake force of the driving wheel derived by the first derivation unit, and sets a value where pressure medium fills a flow channel to the friction brake force by the first friction brake just after regenerative cooperation braking is started. The friction brake force by the first friction brake is not decreased with the lapse of time during the regenerative cooperation braking.SELECTED DRAWING: Figure 1
