DEVICE FOR REGULATING THE SPEED OF A MOTOR VEHICLE POWERED BY AN INTERNAL COMBUSTION ENGINE

Abstract

Abstract Translated from French CE DISPOSITIF COMPREND DEUX GENERATEURS DE VALEUR DE CONSIGNE COMMANDES PAR PEDALE, DELIVRANT UN SIGNAL D'ACCELERATION ET UN SIGNAL DE DECELERATION, UN GENERATEUR DE VALEUR DE CONSIGNE DELIVRANT UN SIGNAL CORRESPONDANT A LA PREMIERE DERIVEE DE LA VITESSE, UN REGULATEUR COMPARANT DES VALEURS DE CONSIGNE ET REELLES ET UN ORGANE FINAL. LES GENERATEURS DE VALEUR DE CONSIGNE, AYANT UNE POSITION "O", SONT DISPOSES DE MANIERE QU'ILS ENTRENT EN ACTION L'UN APRES L'AUTRE PENDANT LE MOUVEMENT D'UNE SEULE ET MEME PEDALE PAR DEUX PORTIONS SUCCESSIVES (0 A 15 ET 15 A 100) DE LA COURSE A F DE LA PEDALE ET CELLE-CI PRESENTE UNE POSITION D'ARRET (15) ENTRE LES DEUX PORTIONS DE SA COURSE, CE QUI CORRESPOND A UNE DISCONTINUITE DE L'EFFORT K EXERCE PAR LE PIED SUR LA PEDALE. THIS DEVICE INCLUDES TWO SETPOINT VALUE GENERATORS COMMANDED BY PEDAL DELIVERING AN ACCELERATION SIGNAL AND A DECELERATION SIGNAL, A SETPOINT GENERATOR DELIVERING A SIGNAL CORRESPONDING TO THE FIRST DERIVATIVE OF THE SPEED, A COMPARING REGULATOR AND REAL AND A FINAL ORGAN. THE SET VALUE GENERATORS, HAVING AN "O" POSITION, ARE ARRANGED SO THAT THEY TAKE ACTION ONE AFTER THE OTHER DURING THE MOVEMENT OF A SINGLE AND SAME PEDAL BY TWO SUCCESSIVE PORTIONS (0 TO 15 AND 15 TO 100) OF THE AF STROKE OF THE PEDAL AND THIS SHOWS A STOPPING POSITION (15) BETWEEN THE TWO PORTIONS OF ITS STROKE, WHICH CORRESPONDS TO A DISCONTINUITY OF THE EFFORT K EXERCISED BY THE FOOT ON THE PEDAL .
