Loading Condition Estimation of Lateral Dynamics Model for Autonomous Heavy Duty Trucks


At the starting run after changing the load of actual truck, the natural frequencies of bouncing and pitching are measured and then judged referring to the natural frequencies of the ride model. Then, sprung mass, moment of inertia, gravity center location and each axle loads are estimated by the ride model equations also. Lateral dynamics model adopts the estimated parameters so that suit to the load change. How to identify the lateral dynamics model to load change and then how to estimate the model parameters by ride model are explained including the test method.バウンシングとピッチングの固有振動数が計測され乗心地モデルの固有振動数に照して積載量が判定される.更にばね上質量,慣性モーメント,重心位置及び各軸重も乗心地モデル式によって推定される.横運動モデルは推定値に諸元を切替えて積載変化に適応する.横運動モデルの同定法,積載推定法が説明される.
