What does the appearance of ECO in an automatic transmission mean?
1 Answers
When ECO appears in an automatic transmission car, it means the economic driving mode is activated. ECO is an abbreviation derived from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light turns on, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active Eco mode does not have a dedicated button. When the ECO indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars utilize the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to activate Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco but also impact the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not operate under these conditions.
