Abstract
Esta solicitud proporciona un sistema de asistencia de freno, un método de freno y un vehículo eléctrico. El sistema de asistencia de freno incluye un pedal de freno, un motor auxiliar de propulsión, un motor de simulación, un nodo de acoplamiento de fila planetaria y un cilindro principal de freno. El cilindro principal de freno se configura para proporcionar una fuerza de frenado para el vehículo. El pedal de freno, el motor auxiliar de propulsión y el motor de simulación se conectan por separado al nodo de acoplamiento de fila planetaria. El nodo de acoplamiento de fila planetaria se configura para convertir un par de torsión de motor del pedal de freno, una salida de par de torsión de motor por el motor auxiliar de propulsión y una salida de par de torsión de motor por el motor de simulación en una fuerza de acción que actúa sobre una varilla de pistón en el cilindro principal de freno. Se puede aprender de la descripción anterior que, el nodo de acoplamiento de fila planetaria se coloca, de modo que tanto la salida de par de torsión de motor por el motor de simulación como la salida de par de torsión de motor por el motor auxiliar de propulsión se utilizan como la fuerza para accionar la varilla de pistón del cilindro principal de freno. Esto puede reducir un requisito de potencia de salida en un solo motor. Además, cuando se utilizan dos motores para accionar el cilindro principal de freno al mismo tiempo, si un motor falla, el otro motor se puede usar para frenar, de modo que mejore la confiabilidad de todo el sistema de asistencia de freno.
