Abstract

Un sistema de computadora a bordo del vehículo almacena valores en una memoria de una primera unidad de control de motor (ECU) y almacena los valores de respaldo correspondientes en una memoria de una segunda ECU. De esta manera, la segunda ECU proporciona la funcionalidad de respaldo de información para la primera información de la ECU. El sistema puede recuperar un valor de respaldo a partir de una primera ECU y restaura el valor correspondiente en la segunda ECU utilizando el valor de respaldo. En un escenario ilustrativo, si una ECU de motor (EECU) original falla y se instala una EECU de reemplazo, el sistema puede restaurar los valores de respaldo para los parámetros del limitador de velocidad del vehículo VSL a partir de la memoria en una ECU de cabina (CECU) y actualizar la información correspondiente en la EECU de reemplazo con los valores de respaldo.
