Improvement Control in Practical Use Fuel Consumption System Description

Outline

The control system for improved fuel economy 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 economy.

*: 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 accelerator 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.
