The invention discloses a gear shifting control method and device for a hybrid vehicle, electronic equipment and a medium, relates to the technical field of automotive electronics, and aims to control the gear shifting of the hybrid vehicle according to the corresponding relation between a preset gear and a calibrated time length if the vehicle is monitored to be in a gear shifting process and an engine is subjected to smoke limit. Target calibration duration corresponding to the gear of the gearbox at the current moment is determined; according to the current target smoke point torque value of the engine and a target torque upper limit value corresponding to the current engine rotating speed, determining a first whole vehicle demand torque value of at least one target moment within the target calibration duration; and for any target moment, after the target moment arrives, the output torque value of the motor is adjusted according to the first vehicle demand torque value at the target moment, so that the sum of the output torque value of the motor at the target moment and the output torque value of the engine is smaller than or equal to the first vehicle demand torque value at the target moment. According to the method, the power stability in the gear shifting process can be effectively improved.

    本申请公开了一种混动车辆的换档控制方法、装置、电子设备及介质,涉及汽车电子技术领域,若监测到车辆处于换档过程中,且发动机出现烟度限制,则根据预设的挡位与标定时长的对应关系,确定与当前时刻的变速箱挡位对应的目标标定时长;根据发动机当前的目标烟点扭矩值以及与当前的发动机转速对应的目标扭矩上限值,确定目标标定时长内的至少一个目标时刻的第一整车需求扭矩值;针对任意一个目标时刻,在目标时刻到达后,根据目标时刻的第一整车需求扭矩值,调整电机的输出扭矩值,使目标时刻的电机的输出扭矩值和发动机的输出扭矩值之和,小于等于目标时刻的第一整车需求扭矩值。该方法,可以有效提升换挡过程的动力稳定性。
