Powertrain overspeed protection |
摘要 |
A method of inhibiting an overspeed condition in a vehicle powertrain includes monitoring at least one of an engine speed and a transmission input shaft speed of a torque converter that transfers drive torque between an engine and a transmission and determining an operating condition of the vehicle powertrain. The method further includes determining a first threshold speed based on the operating condition and reducing an engine torque request when the at least one of the engine speed and the transmission input shaft speed exceeds the first threshold speed.
