Improvement Control In Practical Use Fuel Consumption System Description - Driver Feedback System
The ecological drive assist system (Eco assist) provides drivers a way to maximize fuel economy by monitoring driving habits. Eco assist has two main components to assist in overall fuel economy: Effective Control and Driver's Feedback System. Used together, they provide the best possible fuel economy.
Driver's Feedback System
The driver feedback system provides real-time driving information and gives drivers an interactive way to practice fuel-efficient driving. The driver feedback system includes two visual aids on the gauge control modue: an ambient meter and an Eco guide.
Ambient Meter
The ambient meter is the background color of the speedometer. It changes color based on data the PCM received from various control units and sensors. The PCM calculates this data, forms an Eco drive profile, and then sends the profile to the gauge control module via F-CAN. When the gauge control module receives the Eco drive profile data, it can respond by changing the background color of the speedometer. During low fuel economy, the ambient meter is blue; at medium fuel economy, the meter is blue-green; and at high fuel economy, it's green.
Eco Guide
The Eco guide is one of the screens in the MID. The vehicle icon on the MID moves forward or backward while driving.
- The more aggressive the acceleration is, the further the icon moves forward.
- The more aggressive the deceleration is, the further the icon moves backward.
Trying to keep the vehicle icon near the center of the circle for better fuel economy driving. Also the color of the area around the vehicle icon changes while driving as well as the ambient meter. It becomes blue with agressive acceleration and deceleration, and blue green as fuel economy gets better, then green when driving in the most fuel efficient style.
Eco Score
The Eco score is a fuel economy average calculated from real-time driving information and the percentage of time the ECON button is on. The Eco score determines how many points are awarded on the Eco guide.
Eco Stage
There are three stages that can be reached on the Eco guide by accumulating Lifetime points. The first stage can grow two leaves on each of the five plant icons; the second can grow four leaves on each plant icon; the third stage can grow a blossom on each plant icon. Each stage is progressively more difficult to reach.
Lifetime Points
This is the accumulated point total for the lifetime of the vehicle. Lifetime points are used to determine which Eco stage has been achieved by the driver. Lifetime points are not deleted when the vehicle's 12 volt battery is disconnected, after resetting the PCM, or after a PCM update. To delete the lifetime points, do the lifetime points resetting procedure.
