ECO The name of Ecology (environmental protection), Conservation (energy conservation) and Optimization (Power) derived synthesis, and some manufacturers also known as “ECON”, but anyway you can understand it as the economy (the economy) is for short.
1.ECO modes described
ECO ECO can be divided into active and non-active mode driving ECO driving mode.
2. The active drive mode ECO description
Usually the active drive mode with ECO button, the owner can choose whether to open, after opening, relating to the driving range setting change, such as the same as the depth of the accelerator pedal corresponding to the throttle opening degree smaller (becomes throttle insensitive), transmission shift logic is more emphasis on economics (upshift earlier), some vehicles will simultaneously adjust the air conditioner output power. Different manufacturers ECO mode setting will be different, but the basic principles are the same, that is to influence the driving characteristics of the vehicle by changing the computer program. Common in Japanese and Korean series vehicles, such as: new Nissan Teana, Dongfeng Honda Civic, Beijing Modern Lang move and so on.
The main principle of the active ECO mode is not very complex, mainly during travel of the vehicle, the condition of the automatic transmission gear, engine speed, vehicle speed, brake and transmission fluid temperature, etc. affecting fuel consumption a comprehensive judgment, analysis, the optimum amount of fuel calculated by the ECU to the engine control unit work, reduce fuel consumption so than normal driving mode. Simply put, at a reasonable range control engine speed, to reduce unnecessary fuel consumption.
Although effective and easy to operate significantly, ECO mode but in certain cases can not play a role. When the vehicle speed exceeds 120 km / h, when the vehicle speed is a priority, self-saving mode failure, in other words, if it exceeds economic speed (typically between 60-90 km / h) are more, then it can not play the ECO mode the role of fuel-efficient. Second, ECO mode is primarily self-control, to be effective, and therefore stop at idle or N, P block and a manual mode, ECO function does not work by the same computer in the vehicle traveling. Third, when a certain resistance is overcome, a large torque output, such as during hill climbing and other circumstances, the ECU determines the priority to ensure sufficient computer power driven vehicle, ECO mode will not work.
3. the non-active drive mode ECO description
ECO distinguish the non-active drive mode to the former it is no dedicated keys, since it is just a reminder, a guiding function. Simply put, it just teaches you how to make fuel-efficient, rather than go through substantial intervention to ECU intelligent control to achieve the purpose of the economy. Such as the Buick Excelle ECO mode is this one.
