Description

Vehicle-mounted lamp self-adaptive control system based on lin bus

Technical Field

The invention relates to the field of vehicle-mounted lamp control systems, in particular to a vehicle-mounted lamp self-adaptive control system based on a lin bus.

Background

The LIN bus is a low-cost serial communication network defined for a distributed electronic system of an automobile, is a supplement to other automobile multi-path networks such as a Controller Area Network (CAN) and the like, and is suitable for application without high requirements on the bandwidth, performance or fault-tolerant function of the network. The LIN bus is based on SCI (UART) data format, adopts a mode of single master controller/multiple slave devices, is a special case in UART, and is a low-cost serial communication network for realizing the control of a distributed electronic system in an automobile. 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.

The vehicle-mounted lamp is a series of lighting appliances carried in an automobile and is mainly divided into an external lamp and an internal lamp, wherein the external lamp is mainly a headlight for lighting for assisting the automobile in running, a turn light, a position indicating light and the like for assisting in running, and the internal lamp is a lighting lamp for lighting arranged on the roof of the automobile.

When the automobile runs to a region with dim light, such as an underground parking lot or a lane without light at night, the interior lamp can illuminate the region in the automobile, so that a driver can search for objects or other work needing light assistance in the automobile, and the driver can conveniently drive the automobile. When the interior lamp is suddenly turned on in a dark area, a new light source is created in an originally closed carriage when the light of the interior lamp is strong, stress reaction can occur to drivers and passengers, the eyesight of the drivers and the passengers can be easily influenced in a short time, and safety accidents are easily induced.
