Embodiment Construction

[0016] figure 1 A power-split hybrid electric vehicle powertrain capable of implementing the improved control system of the present invention is shown in schematic form. figure 1 A transaxle 10 is shown comprising two electric machines (generator 12 and electric motor 14 ) together with an engine 16 . Planetary gear unit 18 provides a mechanical split power transfer path from the engine to torque transfer gearing which transfers drive torque to the axle and differential assemblies shown at 22 for the vehicle's traction wheels. Provides a coordinated vehicle control system that manages the distribution of power from each power source to the traction wheels. This coordination requires control algorithms 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 battery control module (BCM), and a regenerative braking system modul...

Abstract

The present invention provides a control method for an accelerator pedal controlled hybrid electric vehicle. A vehicle powertrain controller includes a fuzzy logic-based adaptive algorithm with a learning capability that estimates a driver's long term driving preferences. An adaptive algorithm arbitrates competing requirements for good fuel economy, avoidance of intrusiveness and vehicle drivability. Vehicle performance is maintained in accordance with a driver's driving style.

Description

technical field [0001] The invention relates to an adaptive real-time driver consultation control for improving the fuel economy of a hybrid electric vehicle, in particular to a control method for a power system of a hybrid electric vehicle for accelerator pedal control. Background technique [0002] Hybrid electric vehicles rely on two power sources to deliver power to the vehicle's traction wheels. One power source is usually an internal combustion engine and the other power source is a battery and an electric motor together 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 U.S. Patent No. 7,467,033, a split power transmission path is established through 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 sun gear of the ...
