Description
Technical Field
The invention relates to the technical field of automobile electronics, in particular to a vehicle-mounted lamp interface self-balancing control system based on a LIN bus.
Background
The automobile electronic is a general term for automobile body electronic control devices and vehicle-mounted electronic control devices. Automotive electronics is considered as a revolution in the development process of automotive technology, and is the most important technical measure for improving the performance of automobiles. In recent years, with the rapid development of information technology and the increasing level of automobile manufacturing industry, the proportion of electronic equipment in the total automobile cost is also increased, and statistically, the proportion of the global automobile electronic equipment cost is increased from 2% to more than 50% from 1970 to 2014. In the last 10 years, 70% of innovations in the automobile industry come from the development and application of automobile electronic technologies and products thereof, the application level of the automobile electronic technologies becomes a main mark for measuring the grade level of automobiles, and the improvement of the application degree is an important means for improving the market competitiveness of automobile manufacturers.
Lin (local Interconnect network) is a low-cost serial communication network used to implement distributed electronic system control in automobiles. The aim of LIN is to provide ancillary functions to existing automotive networks (for example the CAN bus), so the LIN bus is an ancillary bus network. The use of a LIN bus for communication between smart sensors and brakes, for example, CAN provide significant cost savings in applications where the bandwidth and versatility of the CAN bus is not required. In addition to the basic protocols and physical layers defined in the LIN specification, development tools and application software interfaces are also defined. LIN communication is based on sci (uart) data format, using single master/multiple slave mode. Only one 12V signal bus and one node synchronous clock line without a fixed time reference are used. Such low-cost serial communication modes and corresponding development environments have been set by the LIN association as standards. The standardization of LIN will reduce costs for automotive manufacturers and suppliers in developing application operating systems.
The authoritative data show that 60% of traffic accidents occur at night, 22% occur in bad weather, and only 18% occur during well lit days. Therefore, the illumination of the vehicle lamp is closely related to the traffic safety. On one hand, the car lamp with poor light distribution effect cannot meet the lighting requirements of complex road conditions such as sharp curves and steep slopes; on the other hand, in high-speed driving, human eyes are in a continuously tense state, and poor lighting effects easily cause visual fatigue of drivers, so that traffic accidents occur, particularly, due to the development of sensor technologies, more and more intelligent vehicle-mounted lamp automatic control functions are developed, so that the driving control of the vehicle-mounted lamps with low delay and high stability is particularly important, which is reflected in the processing and transmission of a large amount of data of an automobile control system, while the data transmission and processing of the vehicle-mounted lamp control system are greatly limited due to the characteristics of a traditional LIN bus, and the LIN bus cannot be processed in time after a fault occurs at a node to recover data communication, and a fault LIN node has a large risk of diffusion and secondary fault.
