METHODS AND SYSTEM FOR AUTOMATICALLY STOPPING AN ENGINE

The invention discloses methods and systems for automatically stopping an engine. Systems and methods for operating a vehicle that includes an engine that may be automatically stopped and started aredescribed. In one example, an engine may be automatically stopped in response to an electric assisted braking threshold level that is adjusted responsive to vehicle speed so that opportunities to automatically stop an engine may be increased, thereby conserving fuel. 本公开提供了"用于使发动机自动停止的方法和系统"。描述了用于操作车辆的系统和方法，所述车辆包括发动机，所述发动机可以自动停止和起动。在一个示例中，可以响应于电动助力制动阈值水平而使发动机自动停止，所述电动助力制动阈值水平响应于车辆速度而调整，使得可以增加使发动机自动停止的机会，由此节省燃料。
