Abstract: Controlled clutchless shifting of multi-ratio geared electronic shift transmissions coupled directly to the electrical prime mover of a vehicle are disclosed. The adaptive control of electrically shifted manual transmissions incorporated into power-split series electric hybrid heavy vehicles operating over heavy duty drive cycles utilizes a direct coupling assembly that enables bi-directional energy transfer and power transport. An electronic shift transmission provides power amplifying or de-amplifying bi-directional intelligently controlled valve or pathway for available terrain potential or kinetic energy of a rolling mass of a vehicle, while retaining the original function of a transmission by increasing or decreasing mechanical rotating energy of the propulsion power to the rear wheels of a vehicle.

Abstract: An electric propulsion system includes a battery pack and a DC-DC converter. The converter has a bypass switch and semiconductor switches. A traction power inverter module (“TPIM”) rectifies a DC bus voltage on the voltage bus to produce an AC bus voltage. An electric machine is connected to the TPIM and energized via the AC bus voltage. A controller calculates required output power from the converter based on a requested operating mode, and speed and torque of the electric machine. When the output power exceeds a threshold, the bypass switch closes to bypass the converter. When the output power is less than the threshold, the controller uses a minimum loss voltage from a loss map as a target control voltage of the converter to optimize efficiency of the electric propulsion system.
