摘要： A method for operating a vehicle that includes a driveline disconnect clutch is described. In one example, the method adjusts torque of an electric machine in response to a estimated torque capacity of the driveline disconnect clutch. The estimated torque capacity of the driveline disconnect clutch is based on a combined inertia of a dual mass flywheel and the driveline disconnect clutch.

摘要： A hybrid electric vehicle includes a traction battery, traction motor and power inverter therebetween. The power inverter converts the DC power of the traction battery to AC power to drive each phase of the traction motor. The power inverter includes Insulated Gate Bipolar junction Transistors (IGBTs) to modulate the power to the traction motor. The speed at which the IGBTs are modulated impacts the system performance including power loss, voltage overshoot and current overshoot. Using a dual emitter IGBT to provide a current mirror of the drive current, circuitry may be used with the gate drive circuitry such that the gate drive speed may be dynamically adjusted based on characteristics including temperature and traction motor rotational speed.

摘要： A system and method for controlling a hybrid electric vehicle powertrain having an engine, a generator, and a motor connected via a planetary gear set to detect lockup in the planetary gear set and control the powertrain in response. When torque is distributed in an electric mode of operation with the engine disabled, the generator is disabled based at least upon a difference between actual generator speed and an expected generator speed exceeding a threshold, indicating a lockup in the planetary gear set. When the engine is activated and distributes torque through the powertrain, the engine and the generator are disabled based at least upon a difference between engine acceleration and an expected engine acceleration exceeding a first threshold, and a difference between engine speed and ring gear speed being less than a second threshold.
