The present disclosure provides a wheel speed sensor interface circuit, an operation method thereof, and an electronic control system, the wheel speed sensor interface circuit comprising: a first signal processing unit for receiving a first current signal sensed by a high side of a wheel speed sensor and processing the first current signal to output a first voltage signal; a second signal processing unit for receiving a second current signal sensed by a low side of the wheel speed sensor and processing the second current signal to output a second voltage signal; and a verification unit for comparing the first voltage signal and the second voltage signal with each other and verifying whether the first voltage signal and the second voltage signal are normal. According to the present disclosure, reliability and redundancy for a process of transmitting wheel speed information can be secured.

    La présente invention concerne un circuit d'interface de capteur de vitesse de roue, son procédé de fonctionnement et un système de commande électronique, le circuit d'interface de capteur de vitesse de roue comprenant : une première unité de traitement de signal pour recevoir un premier signal de courant détecté par un côté haut d'un capteur de vitesse de roue et traiter le premier signal de courant pour délivrer un premier signal de tension; une seconde unité de traitement de signal pour recevoir un second signal de courant détecté par un côté bas du capteur de vitesse de roue et traiter le second signal de courant pour délivrer un second signal de tension; et une unité de vérification pour comparer le premier signal de tension et le second signal de tension l'un à l'autre et vérifier si le premier signal de tension et le second signal de tension sont normaux. Selon la présente invention, la fiabilité et la redondance pour un processus de transmission d'informations de vitesse de roue peuvent être sécurisées.
