The invention relates to a hybrid electric vehicle and a braking control method thereof. The method includes determining, by a first controller, a total braking amount corresponding to a brake pedal manipulation amount and transmitting a regenerative braking request corresponding to at least a portion of the total braking amount to a second controller; determining a state of a regenerative brakingsystem having a motor and a battery and calculating a regenerative braking execution amount by selectively using a first torque corresponding to a torque command transmitted to a third controller tooperate the motor based on the regenerative braking request or a second torque measured by the third controller based on the determined state; and determining a braking force of a frictional brake based on the calculated regenerative braking execution amount and the total braking amount.
本发明涉及一种混合动力电动车辆及其制动控制方法。所述方法包括:由第一控制器确定对应于制动踏板操作量的总制动量,并且将对应于总制动量的至少一部分的再生制动请求发送到第二控制器。确定具有电机和电池的再生制动系统的状态,并且基于确定出的状态、通过选择性地利用与基于再生制动请求而发送到第三控制器以操作电机的扭矩指令相对应的第一扭矩或由第三控制器测量出的第二扭矩来计算再生制动执行量。基于计算出的再生制动执行量和总制动量来确定摩擦制动器的制动力。
