Abstract
The invention provides a control system with simple structure and low cost of a wiper and a headlight so as to realize automation when the wiper and the headlight are worked in rainy days and reduce accident rate of driving in rainy days. The control system comprises a body controller, a combination switch, a rainfall sensor, the wiper and a headlight assembly, and is characterized in that the body controller is connected with the rainfall sensor through an LIN bus, wherein the body controller is the host node of the LIN bus, and the rainfall sensor is the slave node of the LIN bus; the body controller is connected with the combination switch, the wiper and the headlight assembly through a CAN bus; when the combination switch is an automatic shift, the rainfall sensor detects the strength of the current rainfall and light and produces control signals according to the strength of information of rainfall and light, and then transmits the control signals to the body controller through the LIN bus; and the body controller controls the work of the wiper and the headlight assembly according to the control signals.
Description
Technical field
The invention belongs to technical field of automotive electronics, specially refer to the control system of the windscreen wiper and the headlight of automobile.
Background technology
Along with the continuous development of auto-industry and the continuous progress of state-of-art, people also come height more to the functional requirement of car, wish that particularly automobile increases some automatic guidance functions, and it is safer, easy to allow driving variable get.
At present, domestic and international many automobile vendors have developed rain sensor, can adjust the action of rain brush according to the size that drops on amount of rainfall on glass, its principle is to utilize light emitting diode to send far-infrared rays to glass, utilize photoelectric diode to receive the light that reflects, when glass surface was dry, light almost was that 100% ground is reflected, and photoelectric diode just can receive a lot of reflected light rayss like this.Rainwater on glass is many more, and the light that reflects is just few more, and consequently the rain brush action is fast more, simultaneously the power that rain sensor can also the extraneous light of perception.The work that the above-mentioned windscreen wiper that can utilize rain sensor to come the automatically regulating operating frequency has alleviated chaufeur greatly, popular to people deeply.In general, the visbility of rainy day is all lower, if rain sensor and car light can be connected, makes the switching of car light in the rainy day also realize automation, is certain to reduce greatly the accident rate of rainy day driving.In addition, traditional rain sensor all carries out data exchange by separate lines and other parts, and the extended capability of total system is low, wire harness is lengthy and tedious, cost is high and the wiring of wire harness and electromagnetic screening are had relatively high expectations.
Summary of the invention
The objective of the invention is to propose a kind of simple in structure, the windscreen wiper that cost is low and the control system of headlight, realize automation, reduce the accident rate that the rainy day drives so that the work in the rainy day of car light and windscreen wiper opens and closes.
The control system of windscreen wiper of the present invention and headlight comprises car body controller, combined switch, rain sensor, windscreen wiper and headlight assembly, key is that described car body controller links to each other by the LIN bus with rain sensor, wherein car body controller is the major joint of LIN bus, rain sensor be the LIN bus from node; Described car body controller links to each other by the CAN bus with combined switch, windscreen wiper, headlight assembly; When combined switch is automatic transmission, rain sensor detects current rainfall and light power, and according to rainfall and the strong and weak information generation of light control signal, give car body controller with this control signal by the LIN bus transfer then, car body controller is according to the work of this control signal control windscreen wiper and headlight assembly.
Specifically, rainfall is big more, windscreen wiper to scrape water speed fast more; When light was lower than setting value, car body controller control headlight was lighted.
The control system of above-mentioned windscreen wiper and headlight utilizes car body controller as transfer, realized the communication between rain sensor on the LIN bus and the combined switch on the CAN bus, windscreen wiper, the headlight assembly, thereby integrated function of scraping water and automatic bright lamp automatically, traditional physical construction formula rain brush and switch control lamp have been replaced, can allow chaufeur when rainy day, needn't divert one's attention to consider when to open brush, which kind of speed scrape water with and reach and when turn on light, just can obtain sight line clearly and the suitable water speed of scraping, greatly reduce the accident rate that the rainy day drives.The present invention makes full use of LIN bus and CAN bus, has significantly reduced the use amount of car load wire harness, in the antijamming capability and extended capability that improve communication, has reduced system cost.
Communication packet between car body controller and combined switch, windscreen wiper, the headlight assembly adopts the CAN standard frame format, follows the ISO11898 agreement, repeats no more herein.
Described rain sensor is two bytes according to the LIN message length of rainfall and the strong and weak information generation of light control signal, and its cycle is 100ms.Wherein the particular content of LIN message comprises side light control command, passing light control command and windscreen wiper speed control command information at least.
For avoiding chaufeur not know that the rain sensor et out of order still relies on this system and comes automatic guidance wiper and headlight work, cause and drive danger, preferably also comprise the rain sensor failure message in the above-mentioned LIN message.When rain sensor after car body controller has sent failure message, car body controller can be reminded chaufeur by equipment such as instrument, buzzer phones, chaufeur can in time be realized, manually opened wiper and headlight.Same as above, preferably also comprise the rain sensor miscommunication in the LIN message and detect information, response mis-information.
The control system of windscreen wiper of the present invention and headlight is simple in structure, cost is low, integrated function of scraping water and automatic bright lamp automatically, can allow chaufeur when rainy day, needn't divert one's attention to consider when to open brush, which kind of speed scrape water with and reach and when turn on light, just can obtain sight line clearly and the suitable water speed of scraping, greatly reduce the accident rate that the rainy day drives.
