Title (EN) VEHICLE SPEED ESTIMATOR AND TRACTION CONTROL DEVICE
(FR) ESTIMATEUR DE VITESSE DE VÉHICULE ET DISPOSITIF DE RÉGULATION D'ADHÉRENCE
(JA) 車両速度推定装置及びトラクションコントロール装置
Abstract:
(EN) A vehicle speed estimator is equipped with a means (801) that selects the smallest rotational speed from the rotational speeds of all the wheels sensed with a rotational speed sensing means and calculates a reference wheel speed for a construction vehicle at a prescribed time interval. The means (801) is equipped with a variable time constant, variable filter processing unit (814) that performs low-pass filtering of the smallest rotational speed, and a time constant changing unit (810) that changes the time constant of the processing unit (814) according to vehicle travel conditions.
(FR) L'invention concerne un estimateur de vitesse de véhicule, équipé d'un moyen (801) qui sélectionne la plus petite vitesse de rotation parmi les vitesses de rotation de toutes les roues, détectées à l'aide d'un moyen de détection de la vitesse de rotation, et calcule une vitesse de roue de référence pour un véhicule de travaux publics à un intervalle de temps prescrit. Le moyen (801) est équipé d'une unité (814) de traitement de filtrage variable à constante de temps variable, qui effectue un filtrage passe-bas de la plus petite vitesse de rotation, et d'une unité (810) de changement de constante de temps qui modifie la constante de temps de l'unité (814) de traitement en fonction des conditions de circulation du véhicule.
(JA)  車両速度推定装置は、回転速度検出手段で検出された各車輪の回転速度のうち、最も小さい回転速度を選択し、前記建設車両の参照車輪速度を所定の時間毎に算出する手段(801)を備え、手段(801)は、最も小さい回転速度に低域濾波フィルタ処理を行う時定数可変の可変フィルタ処理部(814)と、車両の走行状態に応じて処理部(814)の時定数を変更する時定数変更部(810)とを備えている。
