摘要： Methods and systems are provided for calibrating a compressor surge line. In one example, a method may include adjusting the compressor surge line based on a vehicle speed in addition to a compressor pressure ratio. For example, at higher vehicle speeds, above a threshold vehicle speed, a less aggressive surge line calibration may be utilized in order to improve drivability while at lower vehicle speeds, below the threshold vehicle speed, a more aggressive surge line calibration may be utilized for NVH mitigation.

摘要翻译： 提供了用于校准压缩机喘振线路的方法和系统。 在一个示例中，方法可以包括除了压缩机压力比之外基于车速来调节压缩机喘振线。 例如，在较高的车辆速度下，高于阈值车辆速度，可以利用较不积极的喘振线路校准，以便在低于车辆速度的车辆速度较低时提高驾驶性能，可以利用更积极的喘振线校准 NVH缓解
