Three interfaces are arranged on a circuit board of the controller and are respectively used for being connected with a rainfall sensor interface, a combined switch interface and a BCM circuit interface. The rainfall sensor mainly comprises a sensor housing and a sensor optical element which are buckled together, a sensor circuit board is arranged in the sensor housing and is internally provided with a sensor control line interface, and a control line bundle assembly is arranged between the rainfall sensor and the controller. The sensor optical element is clung to the windshield so as to sense the rainfall and acquire signals, thus controlling the speed of a windshield motor by a BCM circuit system through the controller so as to realize intelligent rain wiping.
Description
Technical field
The utility model relates to the automatic rain brush control system of a kind of automobile based on BCM.
Background technology
In the existing intelligent wiper system, mainly comprise rainfall inductor, controller,, make the retaining at intermittence of former vehicle become the automatic catch of intelligent wiper system, thereby rain is blowed in the realization intellectuality by replacing the relay of former vehicle.But the prerequisite of this installation be the windscreen wiper system of requirement vehicle without BCM system control rain shaving electrical machine, if the windscreen wiper system of former vehicle need be controlled rain shaving electrical machine through BCM, original like this method can't realize.So, for windscreen wiper system, allow the vehicle of this type realize intelligent windscreen wiper function more complicated through BCM control rain shaving electrical machine speed, problem is more.
The utility model content
The purpose of this utility model provides the automatic rain brush control system of a kind of automobile based on BCM, specially at those through the vehicle windscreen wiper system of BCM control and design, connection by controller, harmless installation of realization and intelligence blow rain, have overcome to realize the problem that intelligence blows rain to the vehicle of rain brush being controlled by BCM.
The purpose of this utility model is to be achieved through the following technical solutions:
Native system comprises controller (1) and rain sensor (2), and controller (1) packet controller shell (3) is characterized in: the inside of controller housing (3) is provided with controller circuit board (4), and there is the control line interface outside of controller circuit board; Rain sensor comprises the sensor outer housing (7) and the sensor optics element (8) of mutual fastening, and the inside of sensor outer housing (7) is provided with sensor circuit board (9), and an end of sensor circuit board (9) is provided with sensor control line interface (10); Be connected with control line tread assembly (11) between rain sensor (2) and the controller (1), the two ends, the left and right sides of control line tread assembly (11) are respectively equipped with the first control line tread assembly plug (12) and the second control line tread assembly plug (13); The control wire harness of controller (1) one interface is drawn two wire harness, and one another is for connecting the control line (5) of BCM system in order to connect the control line (6) of combined switch, and another interface of controller (1) is connected with rain sensor (2) by the signal wire harness and links to each other.Described intelligent wiper autonomous cruise speed system has comprised: signal acquisition module, signal analysis modular converter and automatic control module, each data line links together each parts and forms an automatic rain brush control system, controls the windscreen wiper speed speed of specific vehicle circuit according to the size of rainfall.Allow the connection jaws of rain sensor connect the connection jaws of controller, another interface of controller connects the BCM circuit, and the Interface and Controler with combined switch connect again.Native system makes the original intermittently retaining of windscreen wiper combined switch be defined as automatic catch.When pushing this automatic catch, when the Windshield place has raindrop or rainfall to change, the optical element picked up signal of rain sensor, and reach controller, thereby the controller circuitry signal is big like rain quantitative changeization by the rain speed of blowing of BCM control rain shaving electrical machine, and signal strength also changes thereupon, the speed of blowing rain is corresponding to accelerate or slack-off, makes the Windshield minute surface keep good vision minute surface; If windscreen surface clean (no raindrop, fog, snowfall, liquid foreign matter etc.), photo-sensitive cell does not obtain signal like this, and rain is not blowed in the rain shaving electrical machine break-off, just can realize like this that intelligence blows the rain controllable function yet.
The beneficial effects of the utility model are: simple in structure, quick and easy for installation, can dismantle original BCM circuit system, do not damage original circuit and just realized the automatic rain brush controllable function of this type automobile, reduce the technical risk that the windshield wiper autonomous cruise speed system is installed, technical merit to installation personnel is less demanding, to good by the circuit compatibility of BCM system control rain shaving electrical machine, has greatly improved the practicality and the popularity of automatic rain brush control system.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the decomposition texture scheme drawing of the described windshield wiper autonomous cruise speed system of the utility model embodiment.
Among the figure:
1, controller; 2, rain sensor; 3, relay case; 4, controller circuit board; 5, connect BCM system control line; 6, the control line that connects combined switch; 7, sensor outer housing; 8, sensor optics element; 9, sensor circuit board; 10, sensor control line interface; 11, control line tread assembly; 12, the first control line tread assembly plug; 13, the second control line tread assembly plug.
The specific embodiment
When the concrete use of product, the line that connects the BCM system on the automobile combined switch on the former car is pulled out, plug control unit interface 6, controller 1 is connected with the BCM circuit like this, the inside of controller housing is provided with controller circuit board, and the left part of controller circuit board 4 is provided with two control unit interfaces; Rain sensor comprises the sensor outer housing 7 and the sensor optics element 8 of mutual fastening, and the inside of sensor outer housing 7 is provided with sensor circuit board 9, and an end of sensor circuit board 9 is provided with sensor control line interface 10; Be connected with control wire harness 11 between rain sensor 2 and the controller 1, the control wire harness of controller 1 one interfaces is drawn two wire harness, one for connecting combined switch interface wire harness 6, another connects BCM circuit interface wire harness 5, and controller 1 another interface is connected with rain sensor 2 by the signal wire harness and links to each other.Through after the above-mentioned connection, when switch transfers to retaining at intermittence (automatic catch), if rain sensor 2 detects states such as the raindrop, fog, snowfall, liquid foreign matter of windscreen surface, just issue a signal to controller, through BCM circuit control rain shaving electrical machine, rain shaving electrical machine is made blown the rain action accordingly then; Under the automatic speed regulation state, rain sensor 2 is by the precipitation event on infrared detection vehicle window surface, and corresponding signal do not stopped to pass to controller 1 by the control line tread assembly, controller 1 analytic signal also reaches the corresponding operation of BCM circuit execution, the control rain shaving electrical machine guarantees the driver visual field in the rain clearly; Under manual state, controller logical 1 is crossed the BCM execution and is manually blown the rain original function, realizes the manually function of control rain brush speed control.
