Multi-Mode eTransmission Works with Twin Motors
The UK’s GKN Driveline is talking up its role on the new Mitsubishi Outlander four-wheel drive plug-in hybrid electric vehicle. The vehicle is the world’s first, GKN says, “with ability to charge on-the-go.”
The crossover SUV has GKN’s Multi-Mode eTransmission and a pair of 60-kilowatt electric motors, one in the front and one in the rear, powered by a lithium ion battery.
GKN says that its eTransmission, when used as the front transaxle, offers optimum performance in three different driving modes with two different power sources:
- pure EV mode, with the vehicle’s front and rear axles driven only by the electric motors with the front motor being attached to the GKN Multi-Mode eTransmission. Energy is sourced from the battery;
- series hybrid mode, with the combustion engine driving a generator to charge the traction battery on-the-go while the car is still only driven by its front and rear electric motors; and
- parallel hybrid mode, with the combustion engine’s torque feeding through the eTransmission to the front wheels via a hydraulic clutch (which is disengaged in both other modes). The front and rear motors supplement the gasoline engine. Battery charging occurs as well.
“Mitsubishi Motors has broken new ground,” GKN Driveline global engineering director Rob Rickell said in a release. “We are excited to have played a key role.”
