Abstract
(EN)
A brake control method for predicting and determining lifting of a rear wheel before it actually occurs, thereby enabling control of brake force. Vehicle body deceleration is calculated based on wheel speed obtained by wheel speed sensors (45, 46) (S102). When the calculated value is determined to be above a predetermined value (K1)(S104), the pressure in a front wheel cylinder (3) is reduced by a predetermined value and held at that reduced level (S106). When vehicle body deceleration is determined, for example, to be below a level lower by a predetermined value (α) than the predetermined value (K1)(S108), the front wheel cylinder (3) is released from the pressure holding state (S110) and brake control is returned to ordinary control.
(FR)
L'invention concerne un procédé de commande de frein permettant d'anticiper le soulèvement d'une roue arrière avant qu'il n'ait effectivement lieu, ce qui permet de commander la force de freinage. La décélération de la superstructure du véhicule est calculée sur la base de la vitesse de rotation de la roue obtenue par les capteurs de vitesse de rotation de roue (45, 46) (S102). Lorsque la valeur calculée est supérieure à une valeur prédéterminée (K1)(S104), la pression régnant dans un cylindre récepteur de roue avant (3) est réduite d'une valeur prédéterminée et maintenue à ce niveau réduit (S106). Lorsque, par exemple, la décélération de la superstructure de véhicule est en-deçà d'un niveau qui est inférieur à la valeur prédéterminée (K1) d'une valeur prédéterminée (α) (108), le cylindre récepteur de roue avant (3) est libéré de l'état de maintien de pression (S110) et la commande de frein revient au mode de commande ordinaire.

 後輪の実際の浮き上がりが生ずる前に、後輪浮き上がりの発生を予測的に判定し、ブレーキ力の制御を可能とする。  車輪速度センサ45,46によって得られた車輪速度を基に、車体減速度が演算され(S102)、その演算値が所定値K1を越えたと判定されると(S104)、フロントホイールシリンダ3の圧力が所定圧だけ減圧されると共に、その減圧された圧力に保持され(S106)、車体減速度が例えば、所定値K1から所定値α低い値を下回ったと判定されると(S108)、フロントホイールシリンダ3の圧力保持状態が解除され(S110)、通常のブレーキ制御に戻ることとなる。
