Power-saving apparatus and method for transportation vehicle

A power-saving apparatus for a transportation vehicle, the power saving apparatus comprising:

• an identification module, configured to identify a user;
• a positioning module, configured to retrieve a traveled path of the transportation vehicle, wherein the traveled path comprises of a plurality of road segments;
• a connection interface coupled to the transportation vehicle to receive an energy consumption data;
• a memory unit, configured for storing a user data, the traveled path and the energy consumption data;
• a microprocessor coupled to the identification module, the positioning module, the connection interface, and the memory unit, the microprocessor configured to compute the instantaneous energy consumption of the transportation vehicle while traveling the traveled path, and an average energy consumption associated with each road segment, wherein the microprocessor computes the average energy consumption for each respective road segment with the energy consumption data retrieved for the respective road segment traveled at least twice by the transportation vehicle;
• and
• a warning module coupled to the microprocessor, configured to generate a warning signal;
• wherein the microprocessor operatively compares the instantaneous energy consumption of the transportation vehicle and a first average energy consumption associated with a first road segment as the transportation vehicle travels along the first road segment;
• when the instantaneous energy consumption associated with the first road segment is determined to be larger than the first average energy consumption, the warning module operatively generates a high energy consumption message;
• when the instantaneous energy consumption associated with the first road segment is determined to be lower than the first average energy consumption, the warning module operatively generates a low energy consumption message.
