Vehicle heavy load and empty load judgment method and device

Abstract

The invention provides a vehicle heavy load and empty load judgment method and device. The vehicle heavy load and empty load judgment method comprises the steps of obtaining a heavy and empty load dataset, wherein vehicle speed data corresponding to each historic moment is larger than a first preset threshold value; filtering the heavy and empty load dataset; according to the filtered heavy and empty load dataset, obtaining a heavy load calibrating value and an empty load calibrating value; if the vehicle speed data at the current moment is larger than a second preset threshold value, according to heavy and empty load data of the current moment, the heavy load calibrating value and the empty load calibrating value, obtaining the vehicle state of a vehicle. By filtering out abnormal sensordata and reserving effective sensor data, the data is accumulated in real time, the calibrating values of a heavy load and an empty load are screened out, and thus the heavy load state or the empty load state of the vehicle currently is judged in real time; the device is convenient to install, does not need to be calibrated repeatedly, can achieve automatic calibrating, effectively filter complexroad conditions and improve the accuracy of judgment of the heavy load and empty load of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and more specifically, to a method and device for judging whether a vehicle is overloaded or empty. Background technique [0002] At present, most of the load cells on the market have the problems of high misjudgment rate in complex road sections, difficult installation, and recalibration of heavy and empty load judging parameters for different vehicles. Contents of the invention [0003] The present invention provides a method and device for judging heavy load and no load of a vehicle to overcome the above problems or at least partly solve the above problems. [0004] According to one aspect of the present invention, a method for judging whether a vehicle is overloaded or unloaded is provided, including: [0005] Obtaining a heavy and unloaded data set, the heavy and unloaded data set includes heavy and unloaded data at multiple historical moments, and for the heavy and unloaded d...
