AI Technical Summary
Existing vehicle weight estimation methods require driving on roads with fixed slopes, which limits driving conditions, and resistance estimation affects the accuracy of vehicle weight estimation.
By calculating traction and acceleration from the driving parameters of commercial vehicles, a recursive system equation is constructed using the forgetting factor recursive least squares algorithm to calculate an approximate vehicle weight. Through multiple estimations, a precise vehicle weight estimate is obtained, and unstable data is eliminated to achieve accurate prediction of vehicle weight.
Accurate vehicle weight estimation was achieved under various driving conditions, reducing reliance on drag estimation and improving computational efficiency and accuracy.
