Method and system for displaying efficiency of regenerative braking for environmentally-friendly vehicle

A system for displaying efficiency of regenerative braking of an environmentally-friendly vehicle, comprising:

• a brake pedal sensor (BPS) configured to detect an operation of a brake pedal;
• an accelerator pedal sensor (APS) configured to detect an operation of an accelerator pedal;
• an active hydraulic boost (AHB) configured to calculate a total amount of braking required for braking and an amount of regenerative braking included in the total amount of braking while braking;
• a cluster configured to display various information about the vehicle;
• and
• a controller configured to receive signals from the BPS, the APS, and the AHB, and control display of efficiency of regenerative braking of the vehicle on the cluster based on the received signals.

A non-transitory computer readable medium containing program instructions executed by a processor on a controller, the computer readable medium comprising:

• program instructions that calculate a total amount of braking while braking the vehicle;
• program instructions that calculate a ratio of an amount of regenerative braking included in the total amount of braking;
• program instructions that determine whether the vehicle has stopped due to braking;
• and
• program instructions that, once the vehicle has stopped due to braking, display the ratio of the amount of regenerative braking calculated by the controller on a cluster.
