Abstract

Se describe un método y aparato para el ajuste de la velocidad máxima de la bomba de freno en función del ritmo de cambio de la desaceleración objetivo. Un ejemplo de vehículo incluye una bomba de freno con una velocidad máxima de la bomba. El ejemplo de vehículo también incluye un desacelerador del vehículo para determinar una desaceleración objetivo para la desaceleración autónoma y enviar una señal a la bomba de freno para desacelerar el vehículo con la desaceleración objetivo. El ejemplo de vehículo también incluye un regulador de la velocidad máxima para determinar un ritmo de cambio de la desaceleración objetivo y ajustar la velocidad máxima de la bomba en función del ritmo de cambio.
