What does the on-board instrument mean by showing eco?

ECO is the symbol of green driving mode, which can be divided into passive and active driving modes.

The passive form only has an indicator light on the instrument, which will not interfere with the driver's driving behavior. It only evaluates whether the driver's driving behavior conforms to green driving in real time when the speed exceeds 20 km/h. If it is in economic driving operation, the indicator light of ECO will light up, but if it is more radical and more fuel-efficient, it will not be displayed. Its function is only used as a reminder and will not affect the state performance of the vehicle.

The active economy mode has a switch. After the driver triggers the switch, even if the accelerator is slammed, the vehicle still maintains a moderate acceleration state, and it is difficult for the vehicle to reach a higher engine speed. After the vehicle speed exceeds the economic speed, it will continue to accelerate slowly even if the accelerator is stepped to the end. That is to say, after the start of ECO, the driving computer will reduce the sensitivity to human operation and control the acceleration and driving state of the vehicle more according to the fuel-saving mode.
