What does ECO in automatic transmission mean?
1 Answers
ECO in automatic transmission refers to the car's economical driving mode. ECO is an English abbreviation formed from 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 economical mode has been activated. ECO mode is categorized into active and non-active types. The difference lies in that the active type has a dedicated button, allowing the driver to choose whether to activate it. When the driver presses the ECO mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting 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 dashboard ECO indicator light turns on, it serves merely as a reminder function. ECO automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars use the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can activate the ECO mode. However, it is unnecessary to enable 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 reflect the fuel-saving characteristics of ECO and could also impact the vehicle's power performance. Additionally, 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 deactivate automatically. During idle parking or in N/P gear and manual mode, ECO may also become ineffective. When high torque output is required, such as when climbing a hill, the engine's computer prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not function under these conditions either.
