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.
