Abstract

La presente invención se refiere a un método de control híbrido que involucra controlar un vehículo híbrido en el que cuando un motor de combustión interna está en un estado de encendido, la energía se genera por un motor de generación de energía eléctrica conectado a un motor de combustión interna vía un mecanismo de engranajes, y la asistencia se realiza usando la presión negativa de entrada del motor de combustión interna durante el accionamiento del freno. En este método de control híbrido, una unidad de control establece, como un valor de umbral de la velocidad de rotación, una velocidad de rotación del motor a la que el sonido de golpe de los dientes de engranajes que se produce en el mecanismo de engranajes en el estado de encendido no es un problema en términos de calidad y genera presión negativa mientras se mantiene la velocidad de rotación del motor en el estado de encendido cuando se debe generar presión negativa en el estado de encendido con la velocidad de rotación del motor igual a o mayor que el valor de umbral de la velocidad de rotación. Además, la unidad de control genera presión negativa después de cambiar del estado de encendido a un estado de motorización, en el que el motor de combustión interna se hace girar por el motor de generación de energía eléctrica, cuando se debe generar presión negativa en el estado de encendido con la velocidad de rotación del motor menor que el valor de umbral de la velocidad de rotación.
