Embodiment Construction

[0028] The present invention will be further explained below in conjunction with the drawings:

[0029] The uncertainty of the vehicle driving environment and the non-linear characteristics of the operating state and other man-made uncertain factors lead to the uncertainty of the fuel consumption in the vehicle operation. The present invention proposes a cloud-based reasoning-based vehicle cruise speed planning method, which combines the road conditions of the vehicle with the economic status of the vehicle operation to plan the economic cruising speed change trajectory, and the vehicle uses the economic cruising speed change trajectory when cruising , Which can greatly reduce the fuel consumption of the vehicle and improve the fuel economy of the vehicle.

[0030] The implementation of the method of the present invention includes the following specific steps:

[0031] 1) Establish a database of average fuel consumption per hundred kilometers based on the test data. The database con...

Abstract

The invention relates to a cloud inference-based car cruising speed planning method, which takes the average fuel consumption of a car per 100 kilometers as an economic evaluation index. The planning method has the flow diagram that first, a cloud model of the average fuel consumption per 100 kilometers is established based on experimental data; second, related theories of cloud transform, cloud inference and the like are used for determining a concept tree of cloud model input and outputting variables so as to generate a cloud model rule base of the average fuel consumption of a car per 100 kilometers; a mapping relationship between the input and output variables is generated based on automatic extraction procedures of the cloud inference and the rule base, the economic speed under different driving resistances is extracted based on the mapping relationship, an economic cruising speed changing track which is adapted to the change of driving resistances is planned for these economic speeds, and the car runs at the economic speed corresponding to the driving resistance all the time. Accordingly, the method can improve the fuel economy of the whole car, thereby effectively reducing the average fuel consumption of a car per 100 kilometers and better achieving the purpose of energy conservation and emission reduction.

Description

Technical field [0001] The invention is a method for planning vehicle cruise speed based on cloud reasoning. It can switch between different driving resistance conditions according to the road conditions and climate environment parameters when the car is cruising, and plan the change trajectory of the economic cruising speed. Background technique [0002] During the "Eleventh Five-Year Plan" period, the country proposed an energy saving and emission reduction strategy. During the "Twelfth Five-Year" period, my country continued to implement energy conservation and emission reduction, and then proposed a specific strategy for "energy-saving and new energy vehicles". And emission performance constantly puts forward new requirements. [0003] Existing cruise technology has a certain degree of fuel economy, but this cruise mode takes the comfort and safety of the vehicle as a control objective, and cannot maximize the fuel economy of the vehicle. The invention proposes a cloud-based r...
