A kind of regenerative brake control device of vehicle, measurement should (SOC since battery electric power storage dress state (SOC) is the t3 of setting value (SOCs) below<SOCs) the duration of state, and during untill t6 when judging by the short of electricity of stipulated time (Δ TMs), regeneration is limited moment of torsion (Tm_1im) and gradually decrease to zero, during t3~t6, regenerative braking torque (Tm) is limited in a manner of no more than the Tm_1im, so that regenerative braking torque (Tm) gradually decreases to zero.By making regenerative braking torque (Tm) gradually decrease to zero in t3~t6, in the moment t6 as battery power shortage state, regenerative braking torque (Tm) not quick disappearance, can avoid the deceleration of the sense of discomfort as caused by Tm quick disappearance from changing.By the amount of gradually decreasing of friction catch moment of torsion (Tb) compensational regeneration braking torque (Tm), keep synthesis braking torque (Tm+Tb) constant. |
