The invention relates to an engine low-perception starting method and device of a hybrid vehicle, the vehicle and a medium. Comprising the steps that whether a current vehicle has a pre-dragging control requirement or not is judged, when the current vehicle has the pre-dragging control requirement, the first ISG rotating speed of the current vehicle is calculated, and when the first ISG rotating speed is larger than a first preset rotating speed, whether the current vehicle has a rapid dragging requirement and a fuel preparation control requirement or not is judged; and when the current vehicle does not have the rapid drag-up requirement and the fuel preparation control requirement, ignition process rotating speed fluctuation control and/or electromechanical torque interaction control are/is conducted on the current vehicle till the MCU torque of the current vehicle reaches the preset torque or meets the preset electromechanical torque distribution condition. Therefore, targeted strategies are formulated in stages, control is carried out according to different requirements of the vehicle, the problems that the electromechanical torque interaction consistency is poor when the engine is started, and the impact feeling generated to a user when the engine is started is obvious are solved, and the user experience is improved.

    本申请涉及一种混动车辆的发动机低感知启动方法、装置、车辆及介质。包括:判断当前车辆是否存在预拖动控制需求,在当前车辆存在预拖动控制需求时计算当前车辆的第一ISG转速,并在第一ISG转速大于第一预设转速时,判断当前车辆是否存在快速拖起需求和燃料准备控制需求,并在当前车辆不存在快速拖起需求和燃料准备控制需求时,对当前车辆进行起燃过程转速波动控制和/或机电扭矩交互控制,直至当前车辆的MCU扭矩达到预设扭矩或满足预设机电扭矩分配条件。由此,通过分阶段制定针对性策略,根据车辆的不同需求进行控制,解决了发动机启动时机电扭矩交互一致性较差,发动机启动时对用户产生的冲击感比较明显的问题,提升用户体验。
