The Brain: Running the car safely, comfortably and at maximum efficiency

The various devices of the car are centrally controlled by the ECU*, which could be said to be the car's "brain". HYBRID SYNERGY DRIVE uses the ECU to constantly monitor the operational status of these devices, and of energy consumption, on a real-time basis. This enables it to execute quick, precise and comprehensive management to run the car safely, comfortably and with maximum efficiency.

  • Monitors operational status of each hybrid component (petrol engine, generator, electric motors, battery)
  • Monitors braking data received via car's control network
  • Monitors instructions (accelerator pedal opening angle, gear shift position) from the driver
  • Monitors energy consumption of driver assisting-operated systems (e.g. air-conditioning, headlamps, navigation system etc.)
  • Controls each device electronically, based on information derived from monitoring activities listed above, to ensure safe, comfortable and efficient operation of the car.

How does Hybrid synergy drive work?

A petrol-electric hybrid combines the high-speed power of a regular petrol engine with the clean efficiency of an electric motor - eliminating the trade-off between power and efficiency. The Prius hybrid actually stores energy that would otherwise go to waste (eg when decelerating), which is then used when energy demand is high
