SYSTEM AND METHOD FOR CONTROLLING ENGINE TORQUE TO PREVENT DRIVELINE BUMP DURING A DOWNSHIFT WHEN A THROTTLE VALVE IS CLOSED |
摘要 |
A system according to the principles of the present disclosure includes a downshift determination module and a speed control module. The downshift determination module determines when a closed-throttle downshift occurs. The closed-throttle downshift is a downshift of a transmission when a throttle valve of an engine is closed. The speed control module controls engine speed based on turbine speed during the closed-throttle downshift. The turbine speed is a speed of a turbine in a torque converter that couples the engine to the transmission. |
