The embodiment of the invention provides a statistical method and a statistical device for a vehicle mileage in order to solve the problem that the existing mileage statistical method is lower in precision. The method comprises the following steps: classifying region information according to levels, and constructing a node tree for the respective levels of region information, wherein each node corresponds to each level of region; receiving collection information of at least two collection points during vehicle running; screening the respective collection points based on a first presetting algorithm according to the collection information, and obtaining normal collection points; analyzing the normal collection points according to the node tree, and determining the region information corresponding to each normal collection point; determining a running mileage of a vehicle in the respective regions based on a second presetting algorithm according to the region information corresponding to the respective normal collection points. A precise mileage statistical method is implemented; the whole running trace can be divided into small mileages of one or multiple regions; the mileage statistics in the respective regions are performed in sequence, so that regional statistics is realized; meanwhile, the precision of the whole mileage statistics is improved.
Description
technical field [0001] The invention relates to the technical field of vehicle mileage calculation, in particular to a vehicle mileage statistical method and a vehicle mileage statistical device. Background technique [0002] The traditional vehicle mileage statistics is based on the longitude and latitude information of the vehicle's driving trajectory, and according to the time reported by each location point, the distance between each two points is calculated, and then accumulated to obtain the driving mileage. [0003] In the traditional vehicle mileage statistics method, often because of some statistical errors such as drift errors, or in the process of mileage statistics, only one full-time driving trajectory statistics of commercial vehicles from the departure point to the destination is often performed, and the statistical sampling unit is relatively large. This leads to a large deviation in the calculation of the final mileage statistics, which affects the accuracy ...
