What is the ECON function in cars?

[DePeter]

ECON in cars refers to the economy mode, with its full English name being ECONOMY. Working principle: It adjusts various parameters such as transmission gear, engine speed, braking system, transmission oil temperature, etc., through multiple sensors. It comprehensively judges and analyzes conditions that affect fuel consumption, and the ECU control unit calculates the optimal fuel amount to provide to the engine, effectively reducing fuel consumption compared to normal driving modes. The ECU calculates the optimal fuel injection amount to achieve fuel-saving purposes. Simply put, it controls the engine speed with reasonable gear shifts to reduce unnecessary fuel consumption. When the automatic transmission operates in economy mode, its shifting pattern ensures the engine frequently runs within the economical speed range during driving, thereby improving fuel efficiency. ECON mode is divided into active and passive types: Active ECON has its own button, allowing the driver to choose whether to activate it. When the ECON mode switch is pressed, the dashboard indicator light turns on, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Passive ECON mode does not have a dedicated button. When the ECON indicator light on the dashboard turns on, it serves as a reminder function. ECON automatically evaluates driving behavior, and when the current driving operation achieves the optimal fuel supply, the dashboard simultaneously displays the ECON indicator light. Modern automatic transmissions are designed with different shifting logics in the electronic control unit to meet the driving requirements of different people and adapt to various road conditions. A mode selection switch is provided on the control panel, allowing the driver to choose the transmission control mode. Common automatic transmission control modes include the following: Standard driving mode (NORMAL): This is the most commonly used mode in cars. In this mode, every aspect of the car's performance is balanced, such as fuel efficiency, quietness, and power. It achieves the best balance between fuel economy, quietness, and power performance, making it suitable for city driving. Power mode (POWER): This control mode is designed with shifting patterns aimed at maximizing the car's power performance. In this mode, the automatic transmission's shifting pattern ensures the engine frequently operates within the high-power range during driving, thereby enhancing the car's power performance and climbing ability.
