The invention relates to the technical field of automobile control, and discloses a hybrid electric vehicle engine torque control method and device.The hybrid electric vehicle engine torque control method comprises the steps that change data of an accelerator are collected through an accelerator sensor, and whether the collected value meets a preset condition or not is judged; when a preset condition is met, the current target running state of the automobile is determined through the collection value, and when the current running state of the automobile does not meet the target running state, driving modes are switched; after the driving mode is determined, an engine torque reference value in the current driving mode is selected; and the current engine torque is observed, and based on the engine torque reference value, the RBF neural network PID controller is used for controlling the engine torque. Effectiveness and reliability of torque distribution of the hybrid electric vehicle and fuel economy and stability in the working process are achieved.

    本发明涉及汽车控制的技术领域,公开了一种混合动力汽车发动机转矩控制方法及装置,包括通过油门传感器采集油门的变化数据,判断采集值是否满足预设条件;当满足预设条件时,通过所述采集值确定当前汽车的目标运行状态,当汽车当前运行状态不满足所述目标运行状态时,进行驱动模式的切换;确定驱动模式后,选择当前驱动模式下的发动机转矩参考值;观测当前发动机转矩,基于发动机转矩参考值利用RBF神经网络PID控制器对发动机转矩进行控制。本发明实现了混合动力汽车转矩分配的有效性、可靠性,以及工作过程中的燃油经济型、平稳性。
