Embodiment Construction

[0016] figure 1 A powersplit hybrid electric vehicle powertrain capable of implementing the improved control system of the present invention is shown in schematic form. figure 1 Transaxle 10 is shown including two electric machines (generator 12 and electric motor 14 ) along with engine 16 . The planetary gear unit 18 provides a mechanically split power transfer path from the engine to the torque transfer gear arrangement that transfers drive torque to the axle and differential assemblies for the vehicle's traction wheels as shown at 22 . Provides a coordinated vehicle control system that manages the distribution of power from each power source to the traction wheels. This coordination requires a control algorithm to perform a balance of power, speed, and torque from the two power sources.

[0017] The control system includes a controller for the engine 16, a transmission control module (TCM), a high voltage battery and a battery control module (BCM), and a regenerative brak...

Abstract

The present invention provides a control method for an accelerator pedal controlled hybrid electric vehicle powertrain. The vehicle powertrain controller includes a learning-capable fuzzy logic-based adaptive algorithm that estimates the driver's long-term driving preferences. Adaptive algorithms arbitrate competing requirements for good fuel economy, intrusion immunity, and vehicle handling. Maintain vehicle performance according to the driver's driving style.

Description

technical field [0001] The present invention relates to an adaptive real-time driver advisory control for realizing improved fuel economy of a hybrid electric vehicle, in particular to a control method of a hybrid electric vehicle powertrain for accelerator pedal control. Background technique [0002] Hybrid electric vehicles rely on two power sources to provide power to the vehicle's traction wheels. One power source is usually an internal combustion engine and the other is a battery and an electric motor along with a generator. In a so-called power-split hybrid electric vehicle powertrain, a generator is mechanically coupled to the engine and electrically coupled to the battery and electric motor. For example, in US Pat. No. 7,467,033, a split power transfer path is established by a simple planetary gear unit whereby a generator is drivably connected to the sun gear of the planetary gear unit and an engine is connected to the planetary gear unit's sun gear planet carrier...
