The invention provides an automobile engine torque setting method and system.The method comprises the steps that when the maximum torque T of a current automobile is obtained, a first mapping two-dimensional table is created according to a preset first mapping function, and a second mapping two-dimensional table is created according to a preset second mapping function; creating a second interval in the corresponding mapping table broken line graph according to the first mapping two-dimensional table, and creating a third interval in the mapping table broken line graph according to the second mapping two-dimensional table; whether parameters in the first mapping two-dimensional table and the second mapping two-dimensional table are reasonable or not is judged according to the mapping table broken line graph; and if yes, importing the first mapping two-dimensional table and the second mapping two-dimensional table into the Pedal Map for use. By means of the mode, the setting efficiency of the Pedal Map can be improved, and therefore the mapping two-dimensional table and the mapping two-dimensional diagram of different modes can be rapidly obtained and used for perfecting the engine torque Pedal Map in the next step.

    本发明提供了一种汽车发动机扭矩设定方法及系统,该方法包括当获取到当前车辆的最大扭矩T时,根据预设第一映射函数创建出第一映射二维表,并根据预设第二映射函数创建出第二映射二维表;根据第一映射二维表创建出对应的映射表折线图中的第二区间,并根据第二映射二维表创建所述映射表折线图中的第三区间;根据映射表折线图分别判断第一映射二维表以及第二映射二维表中的参数是否合理;若是,则将第一映射二维表以及第二映射二维表均导入Pedal Map中进行使用。通过上述方式能够加快Pedal Map的设定效率,从而能够快速得出不同模式的映射二维表和二维图,供下一步完善发动机扭矩PedalMap使用。
