Re: Revised FAQ
What are the definitions of some of the acronyms that appear at this site?- ICE is Internal Combustion Engine
- DINO (or dino) oil is non-synthetic oil, the stuff that came from dinosaurs (get it?
 )
- FE is Fuel Economy
- ECO is the ECO Switch (hidden to the left of the driver's left knee) that sets the Air Conditioning system to economy mode.
- SOC is State of Charge
- MFD is Multi Function Display (it's found inside your speedometer or on your NAV system)
- NAV is Navigation System
- HSD is Hybrid Synergy Drive (Toyota's name for the hybrid system)
- TCH is Toyota Camry Hybrid
- ECU is the Engine Control Unit. This is the computer "brain" for the entire Toyota Hybrid Synergy Drive system (HSD) and controls all of the energy utilization and recovery.
- MG1 is the smaller motor generator mechanically connected to the Power Split Device (PSD) sun gear. It is utilized by the Engine Control Unit to provide what is the equivalent of a "gear ratio" for the Toyota Hybrid Synergy Drive system (HSD).
- MG2 is the larger motor generator mechanically connected to the driven axle (axles in the Hylander AWD) and the Power Split Device (PSD) ring gear. It is utilized by the Engine Control Unit for electrically driving the vehicle, assisted electric power for the ICE when required and for recovery of excess energy when coasting and braking, sometime called regenerative energy or simply regen.
- PSD is the power split device -- it replaces the transmission in the Toyota Hybrid Synergy Drive system (HSD). Look here to see how it works.
