SYSTEM AND METHOD OF CONTROLLING CRANKSHAFT TORQUE DURING A TRANSMISSION SHIFT WITH TORQUE CAPACITY-BASED TORQUE REDUCTION RANGE SELECTION |
摘要 |
A control system for use with an engine and a transmission in a vehicle is provided that includes at least one controller having a processor with at least one stored algorithm that determines different crankshaft torque capacities associated with different respective torque actuators including a relatively slow torque actuator, such as an airflow actuator, and at least one relatively fast torque actuator, such as a spark actuator or a fuel actuator. The algorithm determines a torque actuation range over which to modify engine torque during an oncoming shift of the transmission. The torque actuation range may be based at least partially on a target gear of the upshift, desired shift duration, and a vehicle operating condition indicative of an operator intent regarding shift duration. Requests for torque modification by use of the torque actuators are then made to provide the torque actuation range.
