A traffic light signal timing learning system and related method include a camera configured on a vehicle to obtain a traffic light signal when approaching a traffic light; a global positioning system (GPS) sensor to simultaneously obtain GPS location of said vehicle; and a control module to record the traffic light signal, time information and GPS location. The learned information is stored in a table in the control module and in a cloud server as a traffic light map, which in turn can be used for optimizing vehicle speed or optimizing the utilization of the power from different vehicular power sources, which consequently improves the vehicle's energy efficiency as well as driving comfort.
