Show moreThis 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.

Show moreA 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. Sponsorship: Illinois Institute of Technology United States Patent Show less

Show moreAn 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. Sponsorship: Illinois Institute of Technology United States Patent Show less
