The invention provides methods and a system for engine control during gear shifting in a hybrid electric vehicle. Methods and systems are provided for controlling engine operation in response to a request to shift a transmission gear. In one example, a method may include maintaining operating conditions of an engine and redirecting electric power generated via the engine from a traction motor to abattery in response to a request to shift a transmission while the driveline is operating in a series mode. In this way engine efficiency may be improved and a time frame for shifting a transmissiongear may be reduced responsive to a gear shift request while the powertrain is operating in series mode.

    本公开提供了“用于混合动力电动车辆换挡期间发动机控制的方法和系统”。提供了用于响应于对变速器换挡的请求而控制发动机操作的方法和系统。在一个示例中,一种方法可以包括:维持发动机的工况并且当传动系以串联模式操作时响应于对变速器换挡的请求而将经由所述发动机产生的电力从牵引马达重新引导到电池。通过这种方式,当动力传动系统以串联模式操作时,响应于换挡请求,可以改善发动机效率并且可以减少用于将变速器换挡的时间范围。
