Improvement Control in Practical Use Fuel Consumption System Description - Effective Control
Outline
The control system for improved fuel efficiency in actual traffic aims at disseminating eco-driving. It consists of an effective control system that is activated by operating the ECON switch to set the ECON ON mode. When the ECON mode is ON, the engine control system, the cruise control system*, the transmission control system, and the air conditioning system work to control fuel consumption by reducing the negative effects of the driver's driving style in an attempt to improve fuel efficiency.
*: There are cases where it is not controlled depending on the vehicle model.

Change of ETCS system control
The opening of the throttle valve is changed by response of the acceleration pedal .
Transmission Control System
- Change in shift map allocation against accelerator full pedal depression
- Moderation of gear change responsiveness
Air Conditioning (A/C) System
- Switching to the recirculation mode
- Reduction in compressor operation frequency
- Lower flow rate
Ambient Meter Function
The ambient meter function evaluates the driver's driving from a fuel consumption perspective and displays its information via the ambient meter in the gauge control module.
