The present disclosure provides a method and system for power matching during a downshift. A method for downshifting a vehicle having an automatic transmission is described. In one example, the method determines whether or not conditions are met for a power matching downshift. If conditions are met for a power matching downshift, output power of a powertrain propulsion torque source at an end of the power matching downshift is adjusted to an output power of the powertrain propulsion torque source at the beginning of the power matching downshift plus an offset power.
本公开提供了“用于在降挡期间进行动力匹配的方法和系统”。描述了一种用于使具有自动变速器的车辆降挡的方法。在一个示例中,所述方法确定是否满足动力匹配降挡的状况。如果满足动力匹配降挡的状况,则将在所述动力匹配降挡结束时动力传动系统推进扭矩源的输出动力调整为在所述动力匹配降挡开始时所述动力传动系统推进扭矩源的输出动力加上偏移动力。
