Abstract

The utility model provides a car window automatic closing control system based on a controller area network (CAN) bus, which comprises a car window motor and a car window motor driving circuit, wherein the car window motor driving circuit is connected with the car window motor. The car window automatic closing control system based on the CAN bus is characterized in that a raindrop sensor is installed on a car, a central controller is arranged in the car, and the raindrop sensor is connected with the central controller. Glass position sensors for detecting window glass top edge positions are respectively arranged on windows and connected with the central controller through the CAN bus, and the central controller is connected with the car window motor driving circuit through the CAN bus. The car window automatic closing control system based on the CAN bus can close the windows automatically when rain falls suddenly.

Description

The automatic closing control of car vehicle window system based on the CAN bus

Technical field

The utility model relates to a kind of car vehicle window control device, is specifically related to a kind of automatic closing control of car vehicle window system based on the CAN bus.

Background technology

CAN (Controller Area Network) bus is a kind of serial local area network bus, is a kind of serial communication network of effective support distributed real-time control, and the signal that existing part automobile adopts the CAN bus to carry out partial function transmits and control automatically.But the window lifting of existing car all is still and relies on driver or passenger's control; When prominent chance the in driving procedure rained; If vehicle window was in and did not have other passengers in open mode and the car this moment; Then the four sides glass for vehicle window all need rely on the driver to rise, and has following shortcoming: 1, because the driver must be eager to vacate a hand and be closed vehicle window, and must observe the open and-shut mode of four sides vehicle window; The driver is diverted attention, cause unsafe factor; 2, because the each operation of driver is done and manyly can only be risen two surface glasses simultaneously, and therefore four vehicle windows must be divided into twice operation, and are time-consuming longer, make two vehicle windows of closing at last since lag behind close and can by rainwater sprinkle into; 3, for the car that is provided with the vehicle window rain shade; Though desirable fastening position is to make edge, glass for vehicle window top concordant with edge at the bottom of the vehicle window rain shade (can rainproofly keep again ventilating); But because the position of glass for vehicle window is difficult to accurate control; The driver who is driving is difficult to glass for vehicle window is driven near ideal position (even the passenger also is difficult to disposablely exactly glass for vehicle window is driven into ideal position, often needing back and forth fine setting several times could realize that glass for vehicle window rests on the ideal position) with settling at one go.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of automatic closing control of car vehicle window system based on the CAN bus is provided, and it can close vehicle window automatically prominent the chance when raining.

Its purpose can realize by following scheme: should comprise Car window electric machine, Car window electric machine drive circuit based on the car vehicle window automatic closing system of CAN bus; The Car window electric machine drive circuit is connected to Car window electric machine; Its main feature is; Raindrop sensor also is installed on car, is provided with central controller in car inner, Raindrop sensor is connected to central controller; Also be respectively equipped with the glass position sensor of inspection vehicle window glass top along the position at each vehicle window, the glass position sensor is connected to central controller through the CAN bus; Central controller is connected to the Car window electric machine drive circuit through the CAN bus.

Be preferably, be provided with the vehicle window rain shade above the vehicle window, be provided with at the bottom of the reflection vehicle window rain shade vehicle window rain shade positional information unit in the central controller along positional information.

The utlity model has following advantage and effect:

If 1, the utility model prominent chance in driving procedure rained; Raindrop sensor is with picked up signal; And notify central controller with rain signal, central controller is judged each glass for vehicle window position, if glass for vehicle window is in open mode; Then Car window electric machine is rotated, glass for vehicle window is risen through the Car window electric machine drive circuit.

2, can avoid the driver to divert attention or rise hand, run into when raining, whether the driver who is driving each vehicle window of inspection of needn't diverting attention again has rise, more needn't rise hand operation to rise glass for vehicle window.

3, run into when raining, the glass of four vehicle windows can rise simultaneously, and avoiding wherein, the glass of two vehicle windows lags behind rise and sprinkles into rainwater.

4, be provided with the vehicle window rain shade positional information unit of representing at the bottom of the vehicle window rain shade along positional information in the central controller; Therefore when central controller judge glass for vehicle window push up rise to along the position with at the bottom of the vehicle window rain shade along the position when concordant; Can order Car window electric machine to suspend rotates; Glass for vehicle window just can accurately rest on ideal position with settling at one go like this, has both prevented that rainwater from sprinkling in the car, keeps again ventilating.

Though 5 four vehicle window present positions in car body disperse, and are in again on the car door, signal transmits relatively difficulty, owing to adopt the CAN bus to communicate in the utility model, has therefore avoided wiring complicated problems in the car.

Description of drawings

Fig. 1 is the principle schematic of the utility model specific embodiment.

Fig. 2 is the prominent desirable fastening position sketch map of meeting when raining of vehicle window.

The specific embodiment

Shown in Figure 1; Should comprise Car window electric machine, Car window electric machine drive circuit based on the automatic closing control of the car vehicle window system of CAN bus; The Car window electric machine drive circuit is connected to Car window electric machine; Raindrop sensor also is installed on the car windshield, is provided with central controller in car inner, Raindrop sensor is connected to central controller; Also be respectively equipped with the glass position sensor of inspection vehicle window glass top along the position at each vehicle window, the glass position sensor is connected to central controller through the CAN bus; Central controller is connected to the Car window electric machine drive circuit through the CAN bus.

Shown in Figure 2, be provided with the vehicle window rain shade above the vehicle window, be provided with at the bottom of the reflection vehicle window rain shade vehicle window rain shade positional information unit in the central controller along positional information.When glass for vehicle window 1 top along the position A point when B point is concordant along the position with 2 ends of vehicle window rain shade; This position is the desirable fastening position of glass for vehicle window 1 when prominent chance is rained; Therefore judge the glass for vehicle window top when central controller and rise to and when the B point is concordant, can order the rotation of Car window electric machine time-out along the position at the bottom of the vehicle window rain shade that glass for vehicle window 1 just can accurately rest on ideal position with settling at one go like this along position A point; Both prevented that rainwater from sprinkling in the car, and kept again ventilating.
