Description

The body control system of low speed paper tape reader static power disspation
Technical field
The utility model relates to a kind of body control system of low speed paper tape reader static power disspation, belongs to technical field of automotive electronics.
Background technology
The function that all multi-users such as Body Control comprises light, scrapes water, door lock, vehicle window, back mirror, seat, environment inside car control can directly perceive is one of key areas embodying vehicle differentiation.Fast development and the improving constantly of consumer demand of automotive electronic industry impel the sector evolution at faster speed, and systems grow is complicated, and function is more and more abundanter, and intellectuality, networking, comfortableization, hommization and personalization level are more and more higher.Meanwhile, some problems are also following, the higher vehicle Body control module of more current configurations reaches more than 20, for the consideration of function and user awareness, major part Body control module all uses normal electricity power supply, quiescent dissipation brings the increasing pressure to car load power-supply system, and the quiescent dissipation how reducing system has become a very important problem.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of body control system of low speed paper tape reader static power disspation, it is introduced center power supply and controls, effective minimizing uses the Body control module quantity of normal electricity always, thus adding one-level quiescent dissipation controlling mechanism, the quiescent dissipation under storing cycle state greatly reduces.
The technical solution of the utility model is achieved in that the body control system of low speed paper tape reader static power disspation, it is characterized in that: MCU connecting triode Q1, aerotron Q2, diode D1 that car body controller (BCM) is inner, car body controller outside connects the coil-end positive pole of center power supply controls relay, and the inner diode D2 that passes through of car body controller keeps off signal with the ignition lock ON of outside and is connected with the coil-end positive pole of center power supply control relay simultaneously; Center power supply controls to connect B+ B+ with relay contact one end, and one end exports controllable electric power; The Body control module of real-time response is needed to be connected with B+ B+ under dead ship condition; Under dead ship condition not real-time response normal electricity power supply Body control module, comprise left front Car's door controlling device, right front Car's door controlling device, left back Car's door controlling device, right back Car's door controlling device, louver controller, automatic air conditioning controller, gateway be not connected B+ B+ with combination instrument, but be connected with the center power supply control controllable electric power that relay exports.
Good effect of the present utility model is that it passes through to introduce center power supply controlling mechanism, and effectively reduce the Body control module quantity always using normal electricity, thus add one-level quiescent dissipation controlling mechanism, the quiescent dissipation under storing cycle state greatly reduces.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, 2, the body control system of low speed paper tape reader static power disspation, it is characterized in that: car body controller 1(BCM) inner MCU connecting triode Q1, aerotron Q2, diode D1, car body controller 1 outside connects center power supply and controls with the coil-end positive pole of relay 2, and car body controller 1 inside keeps off the coil-end of signal and center power supply control relay 2+be extremely connected by diode D2 and the ignition lock ON of outside simultaneously; Center power supply controls to connect B+ B+ with one end, relay 2 contact, and one end exports controllable electric power 5; The Body control module 3 of real-time response is needed to be connected with B+ B+ under dead ship condition; Under dead ship condition not real-time response normal electricity power supply Body control module 4, comprise left front Car's door controlling device, right front Car's door controlling device, left back Car's door controlling device, right back Car's door controlling device, louver controller, automatic air conditioning controller, gateway be not connected B+ B+ with combination instrument, but be connected with the center power supply control controllable electric power 5 that relay 2 exports.
Car body controller 1 controls center power supply control relay by MCU, Q1, Q2, D1 and provides controllable electric power; And realize Redundant Control by D2, circuit ensures ignition lock ON keeps off all Body control modules and has power supply supply; The Body control module of real-time response is needed to be connected with B+ B+ under storing cycle state, originally be operated in normal power mode but under storing cycle state, do not need the Body control module of real-time response not connect B+ B+, but be connected with the center power supply control controllable electric power that relay exports, leave vehicle rear controller 1(BCM) cut off storing cycle state under do not need the module of real-time response normal electricity supply.
1) power-off controls
As shown in Figure 3, using the outer lock operation of car as the mark preparing to exit vehicle, when car body controller (BCM) detect outer without key lock, romote controlled locking, secondary locking, car in control locking wait for bus outer lock operation time, after waiting for that all module afterrun patterns terminate, car body controller controls center power supply control relay and cuts off controllable electric power, namely do not need the Body control module power-off of real-time response under leaving vehicle rear vehicle parked state, system enters low-power consumption mode.
2) upper electric control
As shown in Figure 4, using the outer unlocking operation of car as preparing the mark entering vehicle, when car body controller (BCM) detect without key unblock, remote controlled unlocking, mechanical key unlock wait for bus outer unlocking operation time, connect controllable electric power by center power supply control relay, namely the Body control module of all normal electric sections powers on.It is the reliability of raising system simultaneously, car body controller inside keeps off signal and center power supply control relay coil end+be extremely connected by diode D2 and the ignition lock ON of outside, realize Redundant Control, connection ensures ignition lock ON keeps off all Body control modules and has power supply supply, meet demand of normally driving a vehicle.
