Problems solved by technology

[0007] As mentioned above, the communication methods between the exterior of the vehicle and the interior of the vehicle must be confirmed by humans, and real-time communication cannot be achieved.
When using the ETC system application, because ETC is a microwave induction transmission, if a large amount of data is to be transmitted, the transmission may slow down. In addition, ETC does not transmit vehicle-related data, and the system does not conform to the vehicle transmission protocol. Combine and use with the trip computer function

Abstract

A visible light communication system for vehicles, comprising a signal radiating device comprising a control unit, used for outputting a data signal; a coding unit, connected with the control unit for receiving the data signal, and coding the data signal into a transmission signal; a light emitting unit, connected with the coding unit and having at least one light emitting device for receiving the transmission signal and carrying the transmission signal onto a switch type light-source signal emitted from the at least one light emitting device; and a signal receiving device comprising a light receiving unit, used for receiving the switch type light-source signal carried with the transmission signal, and outputting the transmission signal; a decoding unit, connected with the light receiving unit, for receiving the transmission signal, and decoding the transmission signal into the data signal; and an application unit, used for receiving and identifying the data signal.

Description

technical field [0001] The present invention relates to a visible light communication device for a vehicle, in particular, vehicle-related data and driving status information are carried on a light source signal sent by a vehicle light, and vehicle-related data and driving status information are obtained by receiving the light source signal, and made into a identification and application. Background technique [0002] In the past, the driving status information controlled by the driving computer was only displayed in the vehicle. If you want to obtain the driving status information from the outside of the vehicle, you must enter the vehicle or open the vehicle cover to confirm. General driving status information such as: vehicle speed, brake status, Information on idling time, driving time, tire pressure, engine temperature, water tank temperature, number of passengers and / or seat belt usage status. Vehicle-related information such as: car security code, engine number, wate...
