description Examples described herein provide a computer-implemented method for themial lockout for a motor of a gate crossing mechanism. The method includes monitoring a motor current across a sense resistor of the motor. The method further includes determining a present thermal capacity unit (TCU) at a time interval based on the motor current across the sense resistor. The method further includes determining whether the motor is at a thermal limit by comparing the present TCU to an expected TCU. The method further includes responsive to determining that the motor is at the thermal limit, causing initiating a hard fault. Les exemples décrits présentent un procédé mis en uvre par ordinateur pour le verrouillage thermique dun moteur de commande de barrière. Le procédé comprend la surveillance dun courant de moteur le long dune résistance de détection du moteur. Le procédé comprend aussi la détermination dune unité de capacité thermique actuelle à un intervalle de temps en fonction du courant de moteur le long de la résistance de détection. Le procédé prévoit aussi de déterminer si le moteur est à sa limite thermique par la comparaison de lunité de capacité thermique actuelle à une unité de capacité thermique actuelle attendue. Le procédé comprend aussi le déclenchement dun incident permanent lorsque le moteur serait à sa limite thermique.
