摘要: Systems and methods for starting an internal combustion engine of a hybrid vehicle are presented. In one example, the internal combustion is started via closing a driveline disconnect clutch and limiting a torque output rate of an electric machine so that vehicle speed may increase continuously without decreasing during engine cranking and run-up periods.

摘要: Systems and methods for operating a driveline of a hybrid vehicle are described. In one example, a torque of an engine is adjusted in response to an error between an actual electric machine torque and a minimum electric machine torque plus an offset torque. The reduction of engine torque may be performed when a driveline is operating in a speed control mode.

摘要: Systems and methods for starting an engine that may be started via an electric machine and a driveline disconnect clutch are described. In one example, the method estimates a maximum motor propulsive torque during engine starting. The maximum motor propulsive torque may be based on an estimated speed that a torque converter impeller speed will be when an engine cranking period ends.
