The invention provides a jitter suppression method for an engine. The jitter suppression method comprises the following steps: constructing a delay function and a pulse torque compensation function; a corresponding pulse signal is generated while an ignition signal is generated in each four-stroke cycle; the motor controller starts a monitoring program according to the pulse signal, and the monitoring program generates a pulse compensation instruction according to the delay function and the pulse torque compensation function; and in each four-stroke cycle, the motor controller controls a motor to execute the torque adjustment value corresponding to the pulse compensation instruction according to the pulse compensation instruction and the whole vehicle instruction. According to the method, the jitter time of the engine in each four-stroke period is determined by constructing the delay function, and the torque compensation amplitude of the jitter of the engine is determined by constructing the pulse torque compensation function, so that the jitter of the engine in each four-stroke period can be inhibited and adjusted in time.

    本发明提出了一种用于发动机的抖动抑制方法,包括以下步骤:构建延时函数和脉冲转矩补偿函数;每个四冲程循环内生成点火信号的同时生成相应的脉冲信号;电机控制器根据脉冲信号启动监听程序,所述监听程序根据所述延时函数和所述脉冲转矩补偿函数生成脉冲补偿指令;在每个所述四冲程循环内,所述电机控制器根据所述脉冲补偿指令和整车指令控制电机执行所述脉冲补偿指令对应的转矩调整值。本发明通过构建延时函数确定发动机在每个四冲程周期内发生抖动的时间,构建脉冲转矩补偿函数对确定发动机抖动的转矩补偿幅值,由此保证发动机在每个四冲程周期内发生抖动时可得到及时的抑制调整。
