Embodiment Construction

[0161] The invention is described in further detail below:

[0162] Step 1: Establish an intelligent network connection information collection module. Collect the road information ahead (such as road gradient, etc.) and traffic status information (such as traffic lights, etc.) to provide data support for the optimization of commercial diesel vehicles; collect the current and previous driving conditions (acceleration, speed, Position) is the speed of the preceding vehicle, so as to predict the acceleration and speed of the preceding vehicle in the future. Among them, road information and traffic condition information can be obtained through V-I, V-X medium and high-precision maps, etc.; vehicle speed and acceleration can be obtained through V-V network information, or through sensors such as radar and cameras.

[0163] Step 2: Establish a prediction module for the acceleration and speed of the preceding vehicle. Assuming that the forecast time domain set by the control system is N...

Abstract

The invention discloses a personalized demand-oriented cruise driving optimization control system for a networked commercial diesel vehicle, and belongs to the technical field of intelligent networkedcommercial diesel vehicle control. The invention aims to realize the personalized demand-oriented network connection commercial diesel vehicle cruise driving optimization control system with improvedperformances, such as fuel economy and emission performance, by finding the optimal driving speed track and the optimal vehicle following distance under the personalized target requirements through by adjusting and switching the cruise driving strategy of a vehicle according to the personalized driving demand of a user. The system adopts the following steps: establishing an intelligent network connection information acquisition module, establishing a front vehicle acceleration and vehicle speed prediction module, establishing a power assembly and post-processing integrated model of a diesel vehicle, establishing a safety constraint module, setting four personalized driving modes and the like. The fuel economy, the emission performance and the like of the whole vehicle are improved. The comfort, the economy, the emission performance and the like of diesel vehicles in the formation driving process are improved. The system is applied to modeling and optimal control of various commercialdiesel vehicles.

Description

Technical field [0001] The invention belongs to the technical field of intelligent networked commercial diesel automobile control. Background technique [0002] Commercial diesel vehicles are an important carrier for the rapid development of my country's logistics transportation. Commercial diesel vehicles are large in size and have high wind resistance. Forming multiple large vehicles and driving at a proper distance can reduce the wind resistance of the vehicles, thereby achieving energy saving and emission reduction of individual vehicles. In the process of driving in formation, the acceleration and braking operations of multiple drivers in the team need to be coordinated, so that the following car can closely follow the preceding car. The tightly arranged driving queue has extremely strict requirements for the driver's attention, and the safety performance of the formation has hidden dangers that cannot be underestimated as the speed increases and the distance between vehicl...
