The invention relates to an engine torque control method and device for an automobile starting acceleration working condition. The invention belongs to the technical field of automobile electronic control, and relates to an engine pedal MAP torque control technology of a vehicle carrying an engine and a gearbox in a starting acceleration mode. On the basis of the engine pedal MAP torque in the normal driving mode, the engine pedal MAP torque in the starting acceleration mode specially used in the vehicle starting acceleration process is added. According to the engine pedal MAP in the starting acceleration mode, the torque of the pedal MAP is rapidly increased and tends to be stable before gear shifting is set; after gear shifting, the MAP torque of the pedal is rapidly attenuated, and the self-adjusting torque between the engine and the clutch can be balanced; the engine pedal MAP torque specially used for the automobile starting working condition is independent of the whole automobile running pedal MAP torque, by setting the switching boundary condition, it is guaranteed that the pedal is used during starting accelerator stepping acceleration, and after set gear shifting is achieved, the engine pedal MAP torque is switched to the whole automobile running engine pedal MAP torque.

    本发明涉及一种汽车起步加速工况的发动机扭矩控制方法及装置。本发明属于汽车电子控制技术领域,涉及一种搭载发动机和变速箱车辆在起步加速模式的发动机踏板MAP扭矩控制技术。本发明在正常行驶模式发动机踏板MAP扭矩基础上,增加专门用于车辆起步加速过程的起步加速模式的发动机踏板MAP扭矩。该起步加速模式的发动机踏板MAP,在设定换挡前踏板MAP扭矩快速增加并趋于稳定;在换挡后踏板MAP扭矩快速衰减,可使发动机和离合器之间的自调节扭矩平衡;专门用于汽车起步工况的发动机踏板MAP扭矩,独立于整车车辆运行踏板MAP扭矩,通过设定切换边界条件,保障起步踩油门加速时用该踏板,达到设定换挡后,切换为整车行车发动机踏板MAP扭矩。
