The invention relates to a hybrid electric vehicle, a shift control method thereof, and a computer-readable recording medium. A hybrid electric vehicle includes: an engine; a first electric machine directly connected to the engine; an engine clutch; a second electric machine selectively connected to the first electric machine through an engine clutch; a transmission directly connected to the second motor; a transmission controller configured to determine whether a shift is required for the transmission; and a hybrid controller configured to compare a target torque reduction amount with an intervention limit of the first motor and the second motor to set torque reduction amounts of the engine, the first motor, and the second motor, respectively, when the engine clutch is in a locked state, and output torque commands for controlling torques of the engine, the first electric machine, and the second electric machine, respectively.
本公开涉及混合电动车辆及其换挡控制方法以及计算机可读记录介质。一种混合电动车辆,包括:发动机;第一电机,直接连接至发动机;发动机离合器;第二电机,通过发动机离合器选择性地连接至第一电机;变速器,直接连接至第二电机;变速器控制器,被配置为确定变速器是否需要换挡;以及混合控制器,被配置为当发动机离合器处于锁定状态时,将目标扭矩减小量与第一电机和第二电机的干预限制相比较,以分别设置发动机、第一电机和第二电机的扭矩减小量,并且输出扭矩命令以用于分别控制发动机、第一电机和第二电机的扭矩。
