Title
(EN) ANTISKID CONTROLLER
(FR) UNITE DE COMMANDE ANTIPATINAGE DES ROUES
Abstract
(EN)
An antiskid controller capable of executing precise ABS control by correctly estimating a road surface $g(m) without using an additional sensor. The speed of each wheel is detected, and acceleration of the car body is determined when the difference in speed between the front and rear wheels exceeds a predetermined value. This acceleration is defined by the rate of the change with time of the wheel that has a smaller change in speed, and the road surface $g(m) corresponding to this acceleration is determined. Transverse G is obtained from the difference in speed between the right and left wheels, and corrections for turning, driving on a hazardous road, a change in $g(m) etc., may be executed.
(FR)
Une unité de commande antipatinage permet d'exécuter une commande précise de l'ABS en procédant à une évaluation précise de la surface $g(m) d'une route sans utiliser de détecteur supplémentaire. La vitesse de chaque roue est détectée et l'accélération du véhicule est déterminée lorsque la différence de vitesse entre les roues avant et arrière dépasse une valeur prédéterminée. L'accélération est définie par le taux de variation en temps de la roue dont le changement de vitesse est plus petit, et la surface $g(m) de la route correspondant à cette accélération est déterminée. G transversal est obtenu à partir de la différence de vitesse entre les roues droites et gauches, et des corrections peuvent être apportées pour tourner et conduire sur une route dangereuse, et la valeur $g(m) peut être modifiée.
