Abstract
The utility model relates to an automobile light control system which includes a front light control and a rear light control and is characterized in that the light control system includes five nodes of a body control module, a front light control module, a rear light control module, a combined meter and a brightness sensor. Centering on the body control module, the other four parts are respectively connected with the body control module. An LIN bus hardware interface circuit is adopted as a system line and an intelligent control chip is adopted for the system control to realize the real-time transmission of light information among the five nodes. The automobile light control system has the advantage that line pencils are simplified, which simplify the assembly The automobile light control system also has the advantages of reducing the problems which are caused by the routing, reducing the quantity of the connections and improving the reliability; improving the judging performance and observing the data transmitted among the nodes through the bus.
Description
Technical field
The utility model relates to automotive engineering, particularly discloses a kind of car bulb control system.
Background technology
Usually car bulb is to control by unit switch, drives by relay, protects bulb by fuse, and its shortcoming is the control circuit complexity, and wire harness is various, and controlled function tool is not intelligent.
Along with the continuous development and the continuous application of electronic technology in automotive system of modern electronic technology, the various performances of automobile all are greatly improved.Modern driver and crew are more and more higher to the requirement of automobile various aspects, as visual field property, convenience, comfortableness and recreational etc.Other promotes constantly increase to new controlled function with automotive grade, as central door lock, light control, glass lifting, rearview mirror adjusting, skylight control, seat adjustment and spark delay control etc.Traditional control system adopts relay and stand-alone mode control more, and this makes that the interior wire harness of car is too much and wiring is complicated, thereby has caused serious electromagnetic interference, makes the reliability decrease of system.
Summary of the invention
The purpose of this utility model is to overcome the defective in the prior art car bulb control technology, discloses a kind of safe, fast, car bulb control system efficiently.
The utility model is achieved in that a kind of car bulb control system, comprise the headlight photocontrol, the Rear lamp for vehicle photocontrol, it is characterized in that: lamp light control system comprises car body control module, headlight photocontrol module, Rear lamp for vehicle control module, combination instrument, 5 nodes of luminance sensor, be connected with other 4 parts respectively with the car body control module center, system line adopts LIN bus hardware interface circuit, intelligent control chip is adopted in system's control, realizes car light real-time transmission of information between 5 nodes.
Described LIN bus hardware interface circuit is used the TLE6258 transceiver; Intelligent control chip adopts MC9S12DT128, MC9S08DZ32 model chip.
The application of CAN/LIN bussing technique has replaced traditional wire harness, makes information exchange become safe, fast, efficient.
LIN (Local Interconnect Network) is a kind of novel low-cost serial communication network that is used for the automobile distributed electronic system.It is developed by automobile vendor, is specifically applied to end systems, such as the communication between intelligence sensor and the brake apparatus, uses the LIN bus can save cost greatly.
Native system comprises 5 nodes altogether, car body control module, headlight photocontrol module, Rear lamp for vehicle photocontrol module, combination instrument, luminance sensor, and system has realized car light real-time transmission of information between 5 nodes by adopting the LIN bussing technique.LIN bus hardware interface circuit is used the TLE6258 bus LIN transceiver of company of Infineon, and it is particularly suitable for driving bus in the LIN system in automobile and commercial Application as the interface between protocol controller and physical bus.TLE6258 also provides the vacant working pattern to reduce current drain, has defencive functions such as short-circuit protection and overheat protector.
Intelligent control chip is realized the control of car bulb control system, it is that the model that good vehicle technology development corporation, Ltd. of Shanghai generation section produces is B22-3605010, B22-3605020, B22-3605030, Freescale S08,12 Series of MCU and smart power device have designed high-end automobile-used lamp controll block, forward and backward light control module not only can be realized the control to each car light, and can realize failure diagnosis to each car light, instrument can show the car light fault.
The beneficial effects of the utility model are: wire harness is simplified, and wire harness means that less assembling is simple, reduces the problem that cabling causes, and reduces the quantity that connects, and improves reliability; Improve diagnosis performance, can observe the data of transmitting between the node by bus.
Description of drawings
Accompanying drawing is the utility model frame principle figure.
Embodiment
With reference to the accompanying drawings, light control has dual mode: 1, manual operation, the driver is by the operative combination switch, unit switch is sent corresponding signal into car body controller, car body controller is delivered to signal front or rear lighting control module again by the LIN bus, lighting control module drives corresponding bulb again and lights then, lighting control module also can be monitored the state of bulb always, if abnormal conditions, lighting control module can be delivered to the instrument module with signal by the LIN bus, and the instrument module can show that corresponding fault message is to the driver; 2, light a lamp automatically, when the driver gets to automatic transmission with unit switch, luminance sensor can send corresponding signal by the LIN bus to car body control module according to the variation of environment, car body controller is delivered to signal front or rear lighting control module again by the LIN bus, lighting control module drives corresponding bulb again and lights then, lighting control module also can be monitored the state of bulb always, if abnormal conditions, lighting control module can be delivered to the instrument module with signal by the LIN bus, and the instrument module can show that corresponding fault message is to the driver.
