On existing vehicles, the oil quantity in the fuel tank is often only displayed on the fuel gauge to remind the driver of the current oil quantity on the car, and to refuel in good time, and the oil quantity will not be recorded; in some cases, for example, there is When using a driving recorder, it may also record the fuel volume of the fuel tank, but it is only a record, and these fuel volume data are together with other data of the car state, such as engine speed, speed, etc. In the case of a long time, the data may be overwritten by later data; therefore, when the data needs to be used, the data may be incomplete, the procedures are more, and the cost is higher

The invention relates to a method for obtaining abnormal oil mass data of a car. The method comprises the steps of: obtaining and storing first oil mass data; finding second oil mass data which are obtained and stored before and comparing if a difference between oil tank oil mass data in the first oil mass data and oil tank oil mass data in the second oil mass data is greater than a pre-set value, and judging if the geographical location information of the current car in the first oil mass data and the second oil mass data are same; marking the first oil mass data and the second oil mass data and copying the data into oil mass abnormal data; uploading the oil mass abnormal data and sending out an alarm signal; and storing the current first oil mass data into the second oil mass data. The invention also relates to a device for realizing the method. By implementation of the method and device for obtaining the abnormal oil mass data of the car, disclosed by the invention, the following beneficial effects including complete data, relatively low procedures and relatively low cost are obtained.
Description
technical field [0001] The invention relates to the field of automotive electronic equipment, and more specifically, relates to a method and device for obtaining abnormal oil volume data of an automobile. Background technique [0002] For the monitoring of vehicle status (especially the status of operating vehicles), in addition to parameters related to safety, most people are also very concerned about their fuel volume data. This data is not only related to the history that the vehicle can travel, but in many cases, it is also related to the cost of running the vehicle. For example, it is impossible for operating vehicles to refuel at designated gas stations. In exceptional cases, such as traffic jams, there may be problems with the originally planned amount of fuel; this makes operating vehicles need to refuel at unfamiliar gas stations. At this time, if there are human or other factors, there may be a problem of less refueling and more billing. For example, the actua...
