Adaptive vehicle height adjustment method based on multi-source information fusion

Abstract

The invention discloses a multi-source information fusion self-adaptive vehicle body height adjustment method, which mainly utilizes the vehicle body height adjustment function of the ECAS system to achieve the purpose of reducing fuel consumption. The implementation steps are: based on multi-source sensors to obtain route prediction information, current road condition information, weather status indicators and vehicle speed; use the above information to establish a decision tree model, including the selection and processing of sample data, tree splitting, and decision tree model establishment These three links; when driving in real time, input the information acquired by the above sensors into the decision tree model, output the target height of the vehicle body, combine the vehicle height adjustment strategy, and output the control signal that meets the demand; finally realize the self-adaptive vehicle height adjustment function, and further reduce the fuel consumption purposes. The invention integrates multiple information, enriches the amount of decision-making information, improves the accuracy of decision-making and judgment, and simultaneously considers the vehicle safety performance when building a model, thereby providing safety guarantee for vehicle height adjustment.

Description

technical field [0001] The invention relates to the field of vehicle body height control of an electronically controlled air suspension, in particular to a multi-information fusion self-adaptive vehicle body height adjustment method. Background technique [0002] Motor vehicle driving is a special type of work in driving and transportation. Commercial vehicle driving has relatively high requirements for drivers. With the development of the economy and the increase in the number of commercial vehicles, coupled with the high oil price, how to reduce fuel consumption on the basis of ensuring safety has become a problem that commercial vehicle drivers need to consider. At present, most of the fuel-saving methods adopted are automobile structure transformation, engine technology update and new energy use, etc., and the fuel-saving methods in the process of driving commercial vehicles after leaving the factory are seldom mentioned. The air resistance of the car determines the fue...
