The invention relates to the technical field of new energy automobiles, in particular to a new energy automobile power assembly system with a variable-frequency and variable-speed motor controller, which comprises an automobile data detection module, a mapping relation establishing module and an output power adjusting module, the time in the current automobile running process is divided into a plurality of same time periods, then the road condition in the last same time period in the normal automobile running process is analyzed according to the change of the automobile running speed recorded by the automobile data detection module, and then the battery output power meeting the corresponding speed of the automobile in the current time period during running is called out. The problem that the automobile speed change amplitude is large is avoided, the driving comfort is improved through stable speed control, and by avoiding the too large automobile speed change amplitude, the jolting and pause feeling of the automobile in the driving process and the body discomfort brought to a driver and passengers due to sudden acceleration or deceleration are reduced.
本发明涉及新能源汽车技术领域,具体地说,涉及一种含变频调速电动机控制器的新能源汽车动力总成系统,包括汽车数据检测模块、映射关系建立模块和输出功率调整模块,出功率调整模块通过正常行驶过程中的速度,将当前汽车行驶过程中的时间划分为多个相同时间段,而后通过汽车数据检测模块记录的汽车行驶速度的变化,分析汽车正常行驶过程上个相同时间段中的路况,而后调出符合汽车当前时间段,行驶时对应速度电池输出功率,避免汽车速度变化幅度大的问题,稳定的速度控制提高驾驶舒适性,通过避免汽车速度变化幅度过大,减少车辆在行驶过程中的颠簸、顿挫感以及因突然加速或减速给驾乘人员带来的身体不适。
