The control system that a kind of vehicle window induction type rises
Technical field
The present invention relates to the control system of automobile component, more specifically to
the control system that a kind of vehicle window induction type rises.
Background technology
Along with the development of automotive electronic technology, window lifting controls to control to develop into a present key by original mechanical rocking bar and rises and decline.At present, although achieve the Based Intelligent Control to vehicle window, if forget to close window due to the carelessness of people, safety in car can be caused to be threatened, during as forgotten to close window in sleet sky, be difficult to control on the impact of car inner part infringement.Therefore need to design a kind of vehicle window induction type rising control system and strategy, when preventing car owner from forgetting closedown vehicle window, the damage that sleet causes into the car.
CN201220366180 discloses the vehicle window control system with rainy day automatic window-closing function, comprise car body controller, rain sensor and multiple lifter anti-pinch control modules corresponding with each electric door glassy phase of automobile respectively, described car body controller is connected with rain sensor and each lifter anti-pinch control module by LIN bus, and the output of each lifter anti-pinch control module connects with the elevator motor of corresponding electric door glass.This
inventioncar body controller gathered rainfall information outside car by light sensing formula rain sensor, and this information analyzed and judge, if rainfall exceeds setting value, then controlling lifter anti-pinch and control mould vehicle window is closed.Should
inventionalthough can prevent article in car from drenching with rain, in the process of running at high speed, respond to rainfall automatic lifting windows may damage people, and this system detects rainfall signal always makes car body controller and cannot dormancy, can cause the problems such as dark current increase.
Summary of the invention
The object of this invention is to provide
the control system that a kind of vehicle window induction type rises, it can under parking after electricity, rains and realize vehicle window when not closing vehicle window and automatically close in outside.
The control system that vehicle window induction type of the present invention rises, comprises, car load power detecting module, for judging whether car load power supply is in OFF shelves, if be in OFF shelves, then and native system work, if be in non-OFF shelves, then native system does not work; Rain sensor, for gathering rainfall signal; Rainfall controller, for receiving the rainfall signal that rain sensor collects, and judge that the size of rainfall signal and monitoring rainfall signal send the cycle, when rainfall signal is greater than setting value N, rainfall signal transmission cycle when being less than or equal to X, rainfall signal is sent to BCM controller by LIN bus by rainfall controller, waken up by BCM controller, after the rainfall signal transmission cycle is greater than X, rainfall controller enters park mode; According to the window locations signal of Hall device feedback, BCM controller, for receiving the rainfall signal that rainfall controller is sent, and judging whether vehicle window closes, controlling Car window electric machine running; Battery, powers for giving rainfall controller and BCM controller; With the Car window electric machine of Hall device, Hall device be used for lower electricity time by window locations signal feedback to BCM controller, Car window electric machine is connected with vehicle window executing agency; Vehicle window executing agency, rises for driving vehicle window.
The control system that vehicle window induction type of the present invention rises, owing to only just working after electricity under parking, has evaded in process of running at high speed the injury responded to rainfall automatic lifting windows and may cause people.The present invention wakes car body controller by rainfall controller up by LIN after being greater than setting value to rainfall signal, after solving the lower electricity that stops, time raining and do not close vehicle window in outside, realizes the automatic closedown of vehicle window, avoids the damage of rainwater to article in car.

Detailed description of the invention
In order to explain technical scheme of the present invention further, below in conjunction with
accompanying drawingit is next that the present invention will be described in detail.
See
fig. 1shown in, the control system that this vehicle window induction type rises, comprise car load power detecting module, rain sensor 1, rainfall controller 2, BCM controller 3, battery 6, with the Car window electric machine 4 of Hall device and vehicle window executing agency 5.Described car load power detecting module, for judging whether car load power supply is in OFF shelves, if be in OFF shelves, then native system work, if be in non-OFF shelves, then native system does not work.Described rain sensor 1, for gathering rainfall signal.Described rainfall controller 2, for receiving the rainfall signal that rain sensor 1 collects, and judge that the size of rainfall signal and monitoring rainfall signal send the cycle, when rainfall signal is greater than setting value N, rainfall signal transmission cycle when being less than or equal to X, rainfall signal is sent to BCM controller 3 by LIN bus by rainfall controller 2, waken up by BCM controller 3, after the rainfall signal transmission cycle is greater than X, rainfall controller 2 enters park mode; According to the window locations signal of Hall device feedback, described BCM controller 3, for receiving the rainfall signal that rainfall controller 2 is sent, and judging whether vehicle window closes, controlling Car window electric machine running.Described battery 6, powers for giving rainfall controller 2 and BCM controller 3.The described Car window electric machine 4 with Hall device, Hall device be used for lower electricity time by window locations signal feedback to BCM controller 3, Car window electric machine is connected with vehicle window executing agency 5.Described vehicle window executing agency 5, rises for driving vehicle window.
See
fig. 2shown in, the idiographic flow of the control system that this vehicle window induction type rises is as follows: first judge whether car load power supply is in OFF shelves, if when being in OFF shelves, judge whether the rainfall signal of rain sensor collection is greater than setting value N, when rainfall signal is greater than setting value N and rainfall signal sends the cycle when being less than or equal to X, rainfall signal is sent to BCM controller by LIN bus by rainfall controller, BCM controller is waken up, whether the signal determining vehicle window that BCM controller feeds back to BCM controller according to Hall device closes, if vehicle window is not closed, BCM controller controls Car window electric machine running, and then drive vehicle window executing agency, realize induction type vehicle window to rise.
