There is provided a vehicle having a drive system. The drive system includes an engine for providing electrical power for propelling the vehicle, an electrical energy storage device, a first motor for driving a rotation of a first shaft of the vehicle, and a second motor for driving a rotation of a second shaft of the vehicle. The drive system is configured to operate in a first mode, wherein in the first mode, power for each of the first motor and the second motor is provided exclusively by the electrical energy storage device.

All wheel drive system for hybrid vehicle

A system for controlling a mode of operation of a vehicle having a rechargeable energy storage system (RESS), an engine, and a drive motor coupled to the RESS and the engine, the drive motor selectively powered by at least one of the RESS and the engine includes a controller operable to adjust the vehicle to operate in a plurality of operating modes including a first mode in which the drive motor is powered by the RESS, a second mode in which the drive motor is powered more by the engine than the RESS. When the second mode of operation is selected, controller is configured to operate the engine as necessary to maintain the RESS at or above a predetermined state of charge.

Vehicle operation mode systems and methods

A method of controlling operational modes of a hybrid electric vehicle includes: determining whether an all-electric range (AER) of the vehicle is at or less than a first predetermined value; activating a first operational mode if the AER is determined to be at or less than the first predetermined value; determining, while the first operational mode is active, whether the AER of the vehicle is greater than a second predetermined value; activating a second operational mode if the AER is determined to be greater than the second predetermined value.

Systems and methods for controlling operation of a vehicle

A system for a hybrid vehicle includes an engine; a first inverter coupled to a second inverter; a first electrical machine coupled to the engine and the first inverter; a second electrical machine coupled to the second inverter and a wheel axle of the vehicle; a high voltage battery coupled to both the first inverter and the second inverter; and a switch box disposed between the first electrical machine and the second electrical machine. The switch box includes switches adapted to switch open and closed to allow direct electrical connection from the first electrical machine to the second electrical machine.

Direct electrical connection for multi-motor hybrid drive system

A motor drive system configuration for a vehicle. The motor drive system includes an engine operable for providing power to the vehicle, a motor operable for providing power to a first wheel and a second wheel of the vehicle. The motor drive system also includes a first transmission mounted between the engine and the motor and in operative engagement with the motor and the engine. The first transmission includes a first clutch for coupling and decoupling the motor with the engine. The motor drive system also includes a differential in operative engagement with the transmission and coupled to the first wheel and the second wheel, and a clutch for disabling the connection between the motor and the wheels.

Drive configurations for high hybrid series/parallel high speed motor drive systems

A motor drive system configuration for a hybrid vehicle includes a first motor, a second motor, a differential mounted between the first motor and the second motor, a differential gear, a reduction gear, and a rotatable shaft. The reduction gear includes first end in meshed engagement with the differential gear and a second end. The rotatable shaft includes a first end rotatably coupled to the first motor and a second end rotatably coupled to the second motor. The second end of the rotatable shaft includes a gear in meshed engagement with the second end of the reduction gear. The rotatable shaft has a ninety degree input into the differential and the first and second motors are mounted in-line with the rotatable shaft.
