HV ECU Hybrid Vehicle ECU This is the brains of the HSD receiving and sending signals from all parts of the HSD turning driver request (shift, accelerator, break) into action by parts of the HSD system.

ECM Engine Module controls the ICE (spark, fuel injection, valve timing etc) delivering the proper amount of power to the system under direction of the HV ECU and informs HV ECU of ICE state.

Transmission ECU after receiving On signal from HV ECU monitors the Parking Switch (button) and when pressed it locks the hybrid trans axle and locks when brake is pressed and car is placed in D, R, N

Skid Control ECU Controls regenerative brake effect by MG2 and the hydraulic system to mimic a conventional hydraulic system as well as functions of Brake Assist, ABS (Antilock Brake System) and VSC (Vehicle Stability Control)

ECB ECU = Electronically Controlled Brake integrated into the Skid control ECU to calculate required brake force based on peddle effort and force.

EPS ECU = Electronic Power Steering ECU controls the power assist to steering column calculated from input from the Skid Control ECU and various sensors

Battery ECU monitors the SOC (State Of Charge) and battery temperature communicates with the HV ECU and controls the HV battery cooling fan.

Power Source Control ECU Controls the push button start system receives signals from switches and ECUs communicates to the HV ECU power on power off

Air Conditioning ECU calculates the compressor speed based on input from sensors using a nonlinear fuzzy logic system controls blower speed

Meter ECU Transmits vehicle speed signal, receives information if smart key is in vehicle and sound the warning sound in car on request of other ECUs (the source of the annoying beeps)

Body ECU receives door lock and unlock request and monitors if smart key is in vehicle transmits this to Smart ECU over a serial connection.

Transponder ECU Controls the HV immobilizer by recognizing the key ID code also works with Smart ECU in cars equipped with SKS. Transmits an HV stat authorization to the HV ECU

Smart ECU Checks ID code received from wireless transponders in the car and transmits the code to the Transponder ECU

Navigation ECU provides navigational features as well as Voice recognition and Bluetooth connection.

Fob – this is actually not an acronym but describes the electronic “key” for the Prius. Fob comes from the use of pocketwatches. At one time a man would keep his pocketwatch attached to his vest or jacket by a chain. Eventually a decorative element was added to the chain, it was called a fob. This was then adapted to mean anything decorative attached to a chain, like a key fob. Later fobs took on a utilitarian function as electronic door locks would be opened with fobs.

MG2 – the larger “traction” motor-generator that is connected to the “ring” gear in the planetary gear set. It can also run forwards and backwards. It is DIRECTLY connected to the front drive wheels, and can supply power to move the car, and when regenerative braking occurs it converts motion power from the wheels back into electricity.
