Key features of the Ecological Drive Assist System
1. ECON Mode
ECON Mode applies harmonized control on the CVT and engine to support more fuel-efficient driving.
As soon as the driver presses the ECON button, the system will begin operating and the harmonized control of the CVT, the continuously variable transmission and engine will support more fuel-efficient driving. In addition, ECON Mode automatically achieves energy-saving control of the air-conditioning unit, extends the idle stop time, and increases regenerative recharging during deceleration to achieve more fuel-efficient driving.
2. Guidance function
The Guidance Function provides real-time fuel-efficient driving guidance
To increase driver awareness of more fuel-efficient driving, the ambient meter, which is a background color on the speedometer, notifies the driver of the current driving conditions. The ambient meter displays a green color when fuel-efficient driving is being achieved: a blue-green color when relatively fuel-efficient driving is being achieved with smooth acceleration and deceleration; and a blue color while the vehicle is consuming extra-fuel with bursts of acceleration or deceleration. The ambient meter enables the driver to be aware of real-time fuel consumption patterns, and encourages the driver to achieve fuel-efficient driving while trying to maintain the green color display. In addition, the ambient meter is the world's first such function to support fuel-efficient driving by responding not just to acceleration practices, but to braking practices as well.
3. Scoring function
The aim of the scoring function is to engage drivers in more fuel efficient driving, and encourage them to develop a more environmentally-responsible driving style.
The scoring function is located within the Multi-Information-Display, in the centre of the instrument panel. This part of the Ecological Drive Assist System uses graphics of tree leaves to ‘score' the fuel-efficiency of the driver's performance.
When the ignition switch is turned on, the display shows a score reflecting the real time driving performance.
When the ignition switch is turned off, the ‘leaves' in the top row display a score for the journey just completed, while a horizontal bar in the bottom row of the display gives a ‘lifetime score' that represents cumulative lifetime performance.
The Multi-Information Display also allows drivers to view fuel economy figures for the past three trips, as well as instantaneous and average fuel economy statistics.
When the technology debuts in the Insight in the Spring, it will be the world's first function of its kind to provide real-time and post-trip assessments of the impact of driving habits on fuel economy.
