Embodiment Construction

[0032] See figure 1 , a method for calculating the mileage of a new energy vehicle. When no data packet loss occurs, the method includes the following steps: S1. Install a car networking terminal in the car, use the car networking terminal to collect and store vehicle data, and send The vehicle data is uploaded to the Internet of Vehicles platform in real time. The communication module is WIFI wireless communication. The first memory is set in the Internet of Vehicles terminal, and the first memory is used to store the vehicle data. The second memory is set in the Internet of Vehicles platform, and the second memory is used Real-time storage of uploaded vehicle data;

[0033] S2. Use the Internet of Vehicles terminal to collect and store the status of the car key switch, and upload the status of the car key switch in real time through WIFI wireless communication. Closed state, after the state of the car key switch is collected and uploaded, the first memory and the second mem...

Abstract

The invention discloses a new energy automobile mileage calculation method. The method is suitable for new energy vehicles. Even if the data packet is lost, current mileage information of the automobile can be accurately obtained, so that the automobile mileage calculation precision can be greatly improved. The method comprises the following steps: acquiring vehicle data and uploading the vehicledata in real time; obtaining and uploading in real time the vehicle state; calculating and storing driving mileage information of the automobile in the current vehicle state; vehicle key opening moment; the moment when the vehicle is started by a key, acquiring a current starting mileage Sstart; when the vehicle key is in a continuous start state, acquiring a cumulative mileage Scurrent, and calculating a current mileage Ssegment (N)=Scurrent (N)-Sstart; judging whether a vehicle generates displacement in a mileage section or not, and judging whether data packet loss occurs or not in real time; and performing calibration by adopting a data verification method when data packet loss occurs.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method for calculating the mileage of new energy vehicles based on the Internet of Vehicles. Background technique [0002] In order to facilitate people to understand the mileage information of the car, it is necessary to calculate and record the mileage of each mileage segment of the vehicle. At present, the most direct, simple and fast way to obtain the mileage information of the car is to read the odometer in the vehicle. The mileage information in the table is mainly obtained by multiplying the speed by the time. figure 1 It is the current flow chart of calculating the mileage by multiplying the average speed (Speed) by (*) time (Hours). Acc indicates the state of the car key switch, Acc=On means the car key is on, and Acc=Off means the car key This calculation method has high delay and low accuracy. It uses the average vehicle speed during a period of time mul...
