Embodiment Construction

[0020] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] A car power carrier lighting system, such as figure 1 As shown, it includes the front-end MCU control module, power carrier bus, and terminal lighting control module. The front-stage MCU control module is connected with the front-stage control information, generates carrier-based control information from the front-stage control information and sends the control information to the power carrier bus, and the control information includes left turn, right turn, width indication, high beam , low beam, fog lights, headlights and double flashing control information; the power carrier bus transmits the control information to each terminal lighting control module; the terminal lighting control module takes the control information from the power carrier bus and decodes it into Digital signal to perform corresponding actions on lights.

Abstract

The invention relates to a vehicle power line carrier lighting system and an implementation method thereof. The vehicle power line carrier lighting system is characterized by comprising a preceding-stage MCU control module, a power line carrier bus and a terminal lighting control module; the preceding-stage MCU control module is connected with preceding-stage control information, the preceding-stage control information is generated into control information based on carriers, and then the control information is sent to the power line carrier bus; the power line carrier bus transmits the controlinformation to various terminal lighting control modules; the terminal lighting control modules take the control information out of the power line carrier bus, decode the control information into digital signals, and execute corresponding motions for light. By means of the vehicle power line carrier lighting system and the implementation method thereof, based on the power line carrier bus, data transmission is conducted between the preceding-stage control module and the all the terminal lighting control modules; vehicle power harnesses in the system also play a role of communication channels,the cost is lowered, a circuit is simplified, and all the functions which need to be implemented by the vehicle lighting system are achieved.

Description

technical field [0001] The invention belongs to the field of automobile bus technology, in particular to an automobile electric power carrier lighting system and its realization method. Background technique [0002] With the widespread application of microcontrollers in the field of automotive control, the degree of automotive electronics is getting higher and higher. At present, there are many automotive bus standards, among which CAN bus, J1850, etc. are widely used, among which the lighting control system occupies a major part. The lighting control system needs to use a special data harness and an independent power line, which will increase the manufacturing cost and maintenance difficulty of the car. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, propose an automotive power carrier lighting system and its implementation method, and solve the problems of high manufacturing costs and difficult ma...
