The invention provides a vehicle energy consumption analysis method and system, and the method comprises the steps: firstly collecting the operation data and external environment data of a vehicle, transmitting the operation data and the external environment data to a cloud for data processing, after the cloud completes the processing of related data, according to the calculation results of the vehicle speed consumption electric quantity, the acceleration consumption electric quantity, the brake consumption electric quantity, the high-low voltage load consumption electric quantity, the environment consumption electric quantity and the theoretical electric quantity recovery, analyzing each energy consumption and the proportion of the energy consumption in the whole vehicle energy consumption, and outputting the cause of the energy consumption in the driving process to a user based on the calculation results of each energy consumption; and providing suggestions for improving the drivingstyle for the user through the display module. The technical problems that in the prior art, only the actual consumption value in the energy consumption process can be monitored, the actual energy consumption value cannot be decomposed, and then energy consumption cannot be analyzed from different dimensions are solved.

    本发明提供了一种车辆能耗分析方法及系统,首先采集车辆的运行数据与外部环境数据,并将所述运行数据与所述外部环境数据传输至云端进行数据处理,在云端处理完相关数据后,按照车速消耗电量、加速度消耗电量、制动消耗电量、高低压负载消耗电量、环境消耗电量以及理论电量回收的计算结果,分析各项能耗及其在整车能耗中的占比,并基于各项能耗的计算结果,向用户输出驾驶过程中能耗产生的原因,并通过显示模块向用户提出改善驾驶风格的建议。解决了现有技术只能监测能量消耗过程中的实际消耗值,不能对实际能量消耗值进行分解,进而无法从不同维度分析能量消耗的技术问题。
