Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description, and to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and claims and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is described in further detail, wherein:
Fig. 1 is controller architecture schematic diagram of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；Should be appreciated that preferred embodiment is only for explanation this utility model rather than in order to limit protection domain of the present utility model.
As it can be seen, a kind of controller being applied to automotive tyre pressure monitoring and Body Control that the present embodiment provides, including remote access control system RKE, tire pressure monitoring system TPMS, MCU and control module；Described control module is connected with MCU；Described control module includes that Receiver Module, CAN transmission circuit and BCM circuit, described remote access control system RKE are used for producing RKE radiofrequency signal；Described tire pressure monitoring system TPMS is used for producing tyre pressure sensor radiofrequency signal；Described Receiver Module is used for receiving RKE radiofrequency signal and tyre pressure sensor radiofrequency signal；Described CAN transmission circuit and BCM circuit are connected with MCU.
Described CAN transmission circuit transmits tyre pressure sensor radiofrequency signal by CAN.
Described BCM circuit includes lock control circuit, lamp lighting control circuit, window control circuit and horn control circuit of blowing a whistle；Described lock control circuit, lamp lighting control circuit, window control circuit and horn control circuit of blowing a whistle are connected with MCU respectively.
Also include door interlock switch circuit, lighting switch circuit, car window switch circuit and ignition switch circuit；Described door interlock switch circuit, lighting switch circuit, car window switch circuit and ignition switch circuit are connected with MCU by IO/AD signal input circuit
The distributed car body controller that the present embodiment provides, uses Receiver Module to receive RKE radiofrequency signal and the radiofrequency signal of tyre pressure sensor transmission.MCU is according to the RKE order collected, and in conjunction with other coherent signals obtained, is combined logical judgment, controls door lock, vehicle window, car light and loudspeaker of blowing a whistle and performs corresponding action.Meanwhile, MCU analyzes the tyre pressure sensor signal that receives, obtains present tire pressure and temperature information, and the exception carrying out tire condition judges, such as low pressure, high pressure and high temperature etc., and these information is forwarded in CAN network.
By MCU and coupled control module, including door lock control circuits, window control circuit, lamp lighting control circuit and horn control circuit of blowing a whistle, realize basic door lock, vehicle window, car light and loudspeaker of blowing a whistle and control function, and on this basis correlation function is expanded.
