(JA) ダンプトラックのピッチング制御システム
Abstract:
(EN) Provided is a pitching control system for dump trucks that can improve the ride comfort of a vehicle body and steering stability during travel. This pitching control system for dump trucks comprises: a pitching state amount detection unit 194 which detects the state amount of pitching movement of a vehicle body 10; a spring characteristic calculation unit 197 which calculates the spring characteristics of a suspension cylinder 30 on the basis of the detection results of a stroke sensor 306, a pressure sensor 307, and a temperature sensor 308; a pitching target amount calculation unit 192 which calculates the target amount of pitching movement of the vehicle body 10 according to the spring characteristics calculated by the spring characteristic calculation unit 197; and a torque correction value calculation unit 193 which calculates a torque correction value required for correcting the pitching amount according to the spring characteristics calculated by the spring characteristic calculation unit 197.
(FR) Système de commande de tangage pour camions-bennes qui peut améliorer le confort de conduite d'une carrosserie de véhicule et la stabilité de direction pendant le déplacement. Ce système de commande de tangage pour camions-benne comprend : une unité de détection de quantité d'état de tangage 194 qui détecte la quantité d'état de déplacement de tangage d'une carrosserie 10 de véhicule ; une unité de calcul de caractéristique de ressort 197 qui calcule les caractéristiques de ressort d'un cylindre de suspension 30 sur la base des résultats de détection d'un capteur de course 306, d'un capteur de pression 307 et d'un capteur de température 308 ; une unité de calcul de quantité de cible de tangage 192 qui calcule la quantité cible de déplacement de tangage de la carrosserie 10 de véhicule en fonction des caractéristiques de ressort calculées par l'unité de calcul de caractéristique de ressort 197 ; et une unité de calcul de valeur de correction de couple 193 qui calcule une valeur de correction de couple requise pour corriger la quantité de tangage en fonction des caractéristiques de ressort calculées par l'unité de calcul de caractéristique de ressort 197.
(JA) 走行時の車体の乗り心地や操縦安定性を向上させることができるダンプトラックのピッチング制御システムの提供。本発明は、車体10のピッチング運動の状態量を検出するピッチング状態量検出部194と、ストロークセンサ306、圧力センサ307、及び温度センサ308の検出結果に基づいて、サスペンションシリンダ30のバネ特性を演算するバネ特性演算部197と、バネ特性演算部197によって演算されたバネ特性に応じて、車体10のピッチング運動の目標量を演算するピッチング目標量演算部192と、バネ特性演算部197によって演算されたバネ特性に応じて、ピッチング量の補正に必要なトルク補正値を演算するトルク補正値演算部193とを備えた。
