A hybrid electric drive system including a hydraulic power system for a hybrid powered vehicle which includes a transmission, and a combustion engine and an electric motor both mechanically coupled to the transmission to provide engine and/or motor drive power for the vehicle. A plurality of hydraulic circuits communicate with an electrically driven hydraulic pump. The hydraulic pump is configured to provide fluid circulation to the plurality of hydraulic circuits. The hydraulic circuits are each connected to the transmission and other corresponding vehicle components. An electrical power supply is configured to power the electrically driven hydraulic pump, and the electrical power supply is electrically communicating with a rechargeable high voltage (HV) battery system. The electrically driven hydraulic pump communicates with the plurality of hydraulic circuits to provide fluid pressure in the hydraulic circuits.

Integrated hydraulic supply pump

A hybrid electric drive system is provided for driving a medium or heavy duty vehicle. The drive system includes an internal combustion engine configured as the primary source of motive power. The engine is coupled to a front-most axle and a first drive shaft in mechanical communication with a middle drive axle. The drive system also includes an electric motor and a clutch assembly; and a second driveshaft in mechanical communication with the electric motor and a rear-most drive axle. When the electric motor is not in active operation, the clutch assembly disengages the electric motor from the rear-most drive axle.

Hybrid drive system for hybrid electric vehicles

A system, computer readable storage device and method for controlling torque in a hybrid electric vehicle. The method comprises determining a state of charge of an energy storage device, obtaining a reference state of charge, obtaining an error from a difference between the determined state of charge and the reference state of charge; and apportioning torque between a motor and an engine based upon the error. The motor is electrically coupled to the energy storage device and powered by the energy storage device. A state of charge (SOC) correction factor is determined based upon the error. The SOC correction factor is used to adjust a torque ratio of motor to engine torque that is determined for a given torque command.

Parallel hybrid electric vehicle power management system and adaptive power management method and program therefor

An apparatus for selectively connecting and disconnecting a high voltage source includes a mechanical actuator including a plurality of stations. Each station includes connection elements that are electrically connectable to one or more corresponding high voltage modules which are part of a plurality of high voltage modules. The plurality of high voltage modules are electrically connectable to each other. The mechanical actuator has a connected position and a disconnected position for simultaneously electrically connecting each of the plurality of high voltage modules to each other, and for simultaneously electrically disconnecting each of the plurality of high voltage modules from each other.

Hybrid vehicle high voltage multiple battery disconnect

A method for operating an engine and an integrated starter/generator/motor (ISGM) disposed in a hybrid electric vehicle, which includes launch and deceleration processes. The ISGM is used to both launch the vehicle and start the engine. The deceleration process includes operating a first clutch to disengage the engine from the ISGM during an initial phase, and engaging a second clutch during the initial phase to direct substantially all regenerative energy to provide the only source of electrical energy to recharge the energy storage device.

Method and apparatus for controlling hybrid electric vehicles

A power system for connecting high voltage components includes an enclosure having an interior space. A plurality of high voltage (HV) components are removably coupled to the enclosure and positioned in the interior space of the enclosure. The plurality of HV components are electrically coupled to each other. A motor is positioned outside the enclosure, and the motor is electrically interconnected through the enclosure to one of the HV components. A heat sink is positioned within the interior space for providing thermal heat transfer away from the components.
