Abstract

La materia objeto de la presente invención se refiere generalmente a un vehículo (100). La materia objeto de la presente invención se refiere específicamente a un sistema de monitorización de gases de escape (200) en un vehículo (100). La presente invención elimina la necesidad de un sensor de oxígeno aguas arriba para reducir el costo adicional asociado con un sensor de oxígeno adicional en el vehículo (100). La presente invención determina un valor de sensor de oxígeno aguas arriba a través de un módulo de sensor lambda (203) utilizando entradas de uno o más sensores ya proporcionados en el vehículo (100), tal como velocidad del motor, valor MAP, valor de sensor de temperatura del motor, valor de sensor de posición del acelerador, valor de carga del motor, cantidad de combustible de encendido, tiempo de encendido, etc.
