Vehicle weight prediction method and system, electronic device, medium

Abstract

The invention relates to a vehicle weight prediction method and system, electronic equipment and media. The vehicle weight prediction method includes the following steps: (a) vehicle driving data collection and parameter calculation: obtaining the engine speed, engine load percentage and ECU speed of the vehicle during driving under different load conditions; calculating the current torque and obtaining the current transmission Transmission ratio; (b) segment cutting and constant speed segment screening; (c) correlation vector machine model training; (d) load prediction: for vehicles with unknown load, the average transmission ratio, average vehicle speed and average torque of the filtered segment are input To the relevant vector machine model, the load prediction results of each segment are obtained, and then the vehicle load prediction results are obtained. The method is simple and easy to implement, low in cost, high in efficiency, not limited by site conditions, and can effectively monitor the actual running load of the vehicle.

Description

technical field [0001] The invention relates to the field of transportation, and in particular, to a method and system for predicting vehicle weight, electronic equipment and a medium. Background technique [0002] With the continuous progress of my country's science and technology and society, the road transportation industry has also achieved rapid development. However, due to the lack of effective means of supervision by the traffic control department and the relatively weak national safety awareness, my country's traffic safety situation is becoming increasingly severe. In recent years, although the state has increased investment and emphasis on highway construction and maintenance, especially highways, overloading is still repeated. Overloading of commercial vehicles not only causes damage to the country's highway construction, but also increases traffic Dangerous, many serious traffic accidents are caused by overloading. [0003] The existing vehicle load testing meth...

Problems solved by technology

In recent years, although the state has increased its investment and attention to road construction and maintenance, especially on expressways, the phenomenon of overloading is still repeated. Overloading of commercial vehicles not only damages the country's road construction, but also increases traffic accidents. Dangerous, many major traffic accidents are caused by overloading

[0003] The existing vehicle load test method is limited by factors such as technology, cost and site, and cannot effectively monitor the actual operating load of the vehicle

For vehicle manufacturers, the development and matching of vehicles requires a large amount of load data during the actual operation of the vehicle. If the load estimation is unreasonable, it will have a great impact on the matching and calibration of the power system of the vehicle model, and affect the fuel consumption of the vehicle in actual operation. , emissions and power
