4wdeco is an on-demand four-wheel drive combined with a two-wheel drive energy-saving mode. This means it simulates two-wheel drive when road conditions are good and automatically switches between two-wheel or four-wheel drive based on road conditions when they deteriorate. It is also known as the ECO energy-saving mode. ECO stands for the first letters of the three English words: Ecology, Conservation, and Optimization. It is a car energy-saving mode that, when activated, helps to conserve energy. The principle of ECO: ECO primarily makes comprehensive judgments and analyses during vehicle movement regarding factors that affect fuel consumption, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal amount of fuel to supply the engine, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine's speed with appropriate gear positions to minimize unnecessary fuel consumption.
