Embodiment Construction
[0032] See figure 2 , 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 installed in the Internet of Vehicles terminal, and the first memory is used to store the vehicle data. The second memory is installed 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 t...

The invention discloses a method for calculating the mileage of a new energy vehicle, which is applicable to new energy vehicles, and can accurately obtain information on the current mileage of the vehicle even when data packets are lost, and can greatly improve the calculation accuracy of the mileage of the vehicle. The method Including: obtain vehicle data and upload it in real time, obtain and upload vehicle status in real time, calculate and store the mileage information of the car in the current vehicle state, obtain the current starting mileage when the car key is turned on: Sstart, when the car key continues to start, Acquire the cumulative mileage Scurrent, calculate the current mileage Ssegment(N)=Scurrent(N)-Sstart, judge whether the vehicle has displaced within the mileage segment, and judge whether there is data packet loss in real time. When data packet loss occurs, use Data verification is legally calibrated.
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 indicates that the car key is on, and Acc=Off indicates that the car key This calculation method has high delay and low accuracy. It uses the average vehicle speed during a ...
