CONTROLLING A HYBRID VEHICLE HAVING AN OVERDRIVE COUPLING MEMBER

摘要

A hybrid vehicle includes an engine coupled to a planetary gearset and an electric motor configured to provide motor torque directly to a torque transfer set. An overdrive clutch is configured to, when engaged, bypass at least a portion of engine torque to an overdrive shaft directly connected to the torque transfer set. This allows the engine to also provide torque directly to the torque transfer set along with the motor in an overdrive mode of operation. At least one controller is programmed to control the motor and/or the engine based on an estimated amount of torque transferred through the overdrive clutch.

主权项

1. A vehicle comprising:
an engine; a planetary gearset configured to provide engine torque to a torque-transfer-set; a motor configured to provide motor torque directly to the torque-transfer-set; a coupling member configured to, when engaged, bypass at least a portion of engine torque to an overdrive shaft directly connected to the torque-transfer-set; and a controller programmed to control at least one of the engine and motor based on an estimated torque transferred through the coupling member.
