A hybrid vehicle control system is provided. A vehicle includes an engine, a motor, and a controller. The engine and motor are each configured to deliver torque to a torque converter impeller. The controller is programmed to, responsive to a demanded impeller torque exceeding an upper motor torque threshold while the motor alone is delivering torque to the impeller, increase motor torque to a value that is less than the threshold and that depends on a torque converter bypass clutch torque capacity and a torque converter turbine speed. 本公开提供了"混合动力车辆控制系统"。一种车辆，包括发动机、马达和控制器。所述发动机和马达各自被配置为将扭矩递送到变矩器泵轮。所述控制器被编程为响应于当所述马达单独将扭矩递送到所述泵轮时需求泵轮扭矩超过马达扭矩上阈值，将马达扭矩增加到一个值，所述值小于所述阈值并取决于变矩器旁通离合器扭矩容量和变矩器涡轮速度。
