International Classification:

B60W 10/06
B60W 10/08

US Classification:

180 65265, 180 65275, 903930, 701 22

Abstract:

This invention relates a control strategy for a hybrid electric vehicle having an electric motor, a battery and an internal combustion engine. The control strategy improves fuel economy and reduces emissions while providing sufficient acceleration over a varying set of driving conditions through an adaptive control unit with an artificial neural network. The artificial neural network is trained on a pre-processed training set based on the highest fuel economies of multiple control strategies and multiple driving profiles. Training the artificial neural network includes a training algorithm and a learning algorithm. The invention also includes a method of operating a hybrid electric vehicle with an adaptive control strategy using an artificial neural network.

International Classification:

H02P 7/00

US Classification:

318432, 318433, 318434

Abstract:

A digital controller for controlling variable speed and dynamic torque applications of an electric motor. The controller includes a state observer monitoring a torque load requirement and sending a signal based on the torque load requirement, and a digital control unit for receiving the signal from the state observer and sending an output to the electric motor. The output is a value that corresponds to a first motor operating state or a second motor operating state.

International Classification:

B60K 6/20

US Classification:

180 6523, 180 6521, 180 651, 180 6525, 180 6531, 477 3

Abstract:

This invention relates to a parallel hybrid electric conversion kit for a vehicle with an internal combustion engine, a driveshaft and a transmission, such as, rear wheel drive vehicles, four-wheel drive vehicles, heavy duty multiple-driven-axle vehicles and/or all-wheel drive vehicles. The conversion kit includes a motor-generator, a torque coupler, a battery, a power electronics module and a controller. Suitable torque couplers include transfer cases and/or rear-through differentials. The conversion kit provides an aftermarket solution to increased performance, fuel economy and/or reduced emissions by modifying the drivetrain after the transmission. According to one embodiment of this invention, the control scheme of the installed conversion kit receives input signals from the engine and the motor-generator, but only sends control signals to the motor-generator, facilitating installation of the conversion kit.

B60K 1/00

US Classification:

180 65235, 180 656, 180 657

Abstract:

An electro-mechanical drive train for a hybrid electric vehicle. The electro-mechanical drive train includes a housing and a pinion shaft having a first end disposed within the housing and a second end in communication with a combustion engine. A differential is disposed within the housing and in combination with the end of the pinion shaft. An electric motor is also disposed within the housing and in actuating combination with the pinion shaft.
