Abstract

A BCM (body control module) integrating the functions of an intelligent windscreen wiper and light and arranged in a 24 V system comprises a combined switch, an automatic windscreen wiper switch, an automatic light switch, a BCM and a wiper light sensor, wherein the BCM can receive not only a high-speed, low-speed or intermittence control way of a driver, but also a sensor signal in the automatic mode to control the speed of the windscreen wiper and the on/off of a light automatically. The wiper light sensor is connected with the BCM through an LIN bus; and the BCM provides a 12 V power-supply low-level signal for the wiper light sensor. Rainfall and light information is obtained through a light path emission receiving circuit and an optical device, and is transmitted through the LIN bus to the BCM to control the speed of the windscreen wiper, a dipped headlight and a position light. The BCM is simple in connection structure, omits the hardware facilities in the intermediate link, reduces the cost of a complete vehicle, and improves the reliability of the complete vehicle.

Description

The BCM of the 24V system module of a kind of integrated intelligent windscreen wiper, light function

Technical field

The present invention relates to the BCM of the 24V system module of a kind of integrated intelligent windscreen wiper, light function, relate in particular to the BCM module of integrated intelligent windscreen wiper in the 24V system, light function.

Background technology

The control system of present domestic most intelligent windscreen wipers, light function all is connected with sensor by a separate controller and forms.Because between controller and the BCM is what to separate, just has BCM, WLCM (Wiper Light Control Module rainfall luminosity control module) and rainfall Light indicator in the system.Under this framework, need between BCM and the WLCM be connected through total wire joint or rigid line, also increase the cost of system in the time of the increase system complexity, and reduced the reliability of system.

Summary of the invention

To the problem that exists in the present prior art; The utility model provides the BCM of the 24V system module of a kind of integrated intelligent windscreen wiper, light function; This BCM module integrates the function of BCM function and WLCM, and the input of two parts function common switch amount detects and windscreen wiper light drive part circuit.

For achieving the above object, the utility model adopts following technical scheme:

The BCM of the 24V system module of a kind of integrated intelligent windscreen wiper, light function; Form by combined switch, automatic wiper switch, non-attended light photoswitch, BCM module and rainfall luminosity sensor; Combined switch, automatic wiper switch, non-attended light photoswitch are connected to BCM module by signal receiving end; The rainfall luminosity sensor is through the total wire joint BCM of LIN module, and BCM module mouth is connected to rain shaving electrical machine and car light.This BCM module both can have been accepted windscreen wiper high speed, low speed, the mode intermittently that chaufeur provides, and can when automatic mode, accept sensor signal again, and the automatic guidance windscreen wiper is scraped speed and headlamp switch.Through the total wire joint of LIN, BCM provides 12V power supply and ground level signal for the rainfall Light indicator between rainfall luminosity sensor and the BCM.Accept circuit card with optics is experienced rainfall and light information through light path emission, and pass to BCM module controls windscreen wiper through the LIN bus and scrape fast and passing light, position lamp.

The connection structure of the utility model is simple, has saved the hardware facility of intermediate link, has reduced the cost of car load, and has improved the reliability of car load.

Fig. 2 is said BCM of the utility model and rainfall luminosity sensor communication flow figure.

Fig. 3 is the utility model BCM internal logic decision flow chart.

The specific embodiment

As shown in Figure 1, the BCM of the 24V system module of a kind of integrated intelligent windscreen wiper, light function is made up of combined switch 1, automatic wiper switch 2, non-attended light photoswitch 3, BCM module 4, rainfall luminosity sensor 5.Combined switch 1, automatic wiper switch 2, non-attended light photoswitch 3 are connected to BCM module 4 signal receiving ends, and rainfall luminosity sensor 5 is through the total wire joint BCM of LIN module 4, and BCM module 4 mouths are connected to rain shaving electrical machine 6 and car light 7.

As shown in Figure 2, after car load ON fire was stamped, BCM began to send infomational message to the RLS sensor.This information comprises automatic wiper incoming signal, non-attended light light input signal, windscreen wiper sensitivity signal, windscreen wiper gear signal, windscreen wiper off-position signal etc.BCM judges whether transmission is successful after infomational message sends 20ms, if send the message pick-up pattern that successfully just gets into.The RLS sensor can send windscreen wiper solicited message and light control request infomational message according to rainfall and light status when the BCM transmission accepts request.BCM detected whether accept success after this infomational message sent 20ms, and BCM can finish its working process after receiving successfully, and the message after the handle reception is saved in the correlated variables and handles.

As shown in Figure 3, among the BCM about the working process of operating part.Windscreen wiper high speed or the request of windscreen wiper low speed have been judged whether earlier, when request, relevant output will have been opened that the control motor rotates.Judged whether the light request again, when the light request, just opened passing light and position lamp that passing light and position lamp have output.The windscreen wiper of windscreen wiper and light request and switch control with the light function is or relation, windscreen wiper off-position function with whether be that the request of RLS sensor is irrelevant, whether put in place relevant with the off-position signal.

Claims
