Abstract

A power-saving apparatus for transportation vehicle is provided. The power-saving apparatus includes an identification module for identifying a user, a positioning module for retrieving a traveled path, a connection interface for retrieving energy consumption data, a memory unit for storing the user data, the traveled path, and the energy consumption data, a microprocessor for calculating an instantaneous energy consumption, an average energy consumption associated with the traveled path. The power-saving apparatus further includes a warning module for generating a warning signal. When the instantaneous energy consumption associated with a first road segment is determined to be larger than a first average energy consumption and/or the instantaneous energy consumption associated with a second road segment is determined to be larger than a second average energy consumption, the warning module operatively generates the warning signal.
