  • Commissioning a hybrid drive assembly of a vehicle
    Patent number: 8596404
    Abstract: A method for commissioning a hybrid vehicle includes providing a vehicle having a chassis, a first power source disposed on the chassis and a second power source disposed on the chassis. The first power source includes a prime mover and a transmission. The prime mover is selectively engaged to a driveline of the vehicle. The second power source includes a pump/motor assembly, a fluid reservoir in fluid communication with the pump/motor assembly and an energy storage unit in fluid communication with the pump/motor assembly. A neutral position of the pump/motor assembly is determined. The pump/motor assembly of the second power source is coupled to the prime mover of the first power source during pumping mode of the pump/motor assembly. Gas is purged from the second power source by routing fluid from the energy storage unit to the fluid reservoir.
