Abstract
Provided is a vehicular traffic signal lamp display system which comprises a traffic signal lamp information encoding device, a short-distance radio emitter, a vehicular traffic signal lamp display device, and a vehicular short-distance radio receiver. The short-distance radio emitter performs radio communication with the vehicular short-distance radio receiver. The traffic signal lamp information encoding device encodes the current display information of a road traffic signal lamp. Encoded information is periodically emitted by the short-distance radio emitter. The vehicular short-distance radio receiver receives the encoded information. The vehicular traffic signal lamp display device comprises a decoding device and an electronic compass. The decoding device decodes the encoded display information. The electronic compass measures the current orientation of the front of a vehicle. A processor in the vehicular traffic signal lamp display device selects and displays the encoded information of a traffic signal lamp in the front of the travelling vehicle according to the orientation of the front of the vehicle. The vehicular traffic signal lamp display system improves driving safety and is not restricted by environment.
