A concept transmission in the evaluation phase, the Spicer TE-15HX from Dana Holding is an electric parallel hybrid featuring a dual-power-path transmission control system. This system continuously monitors operating conditions and selects the proper combination of diesel and electric power to optimize productivity while reducing fuel consumption, emissions, noise, and engine idling. Whenever possible, the transmission disengages the diesel engine and supplies power generated by super capacitors for inching and other vehicle operations requiring low energy consumption. It also powers lights, climate control systems, and other electrical accessories. For light loads, the diesel engine works alone to power the vehicle while the electric device serves as a generator to charge the super capacitors for later use. Vehicle braking is also a key source of regenerative energy for recharging capacitors. When additional tractive effort is required, the controller directs the electric device to function as a motor and provides a second source of power for added torque boost and faster takeoff. Targeted for use on material-handling vehicles, the transmission incorporates high-contact-ratio spur gears and helical gearing to reduce noise, while an electronic control system provides electronic clutch modulation, electronically controlled inching, safety inhibit protection, diagnostics, and compatibility with CAN 2.0B protocols. The system will enable OEMs to equip their vehicles with optional safety inhibits, diagnostics, system monitoring, load- and speed-compensated automatic shifting, shift overlap control, single pedal drive, and automatic throttle up.
