Description
Technical field
The present invention relates to the electric vehicle control system technical field, be specifically related to a kind of battery-driven car ignition lock two-way voltage-operated device.
Background technology
In traditional gasoline automobile, only there is a kind of voltage in the car load circuit control system at present, and general-duty ignition lock mode can satisfy the requirement of car load circuit control system on the employing market.
And in pure electric automobile, have two kinds of electrical voltage systems usually: high potential (more than or equal to 72V) and low voltage (12V or 24V); The current consumer that needs high voltage circuit control for electric machine controller (or DC-DC electric pressure converter) etc.; Its solution mainly is on traditional low-pressure system, to increase a kind of electronic module; Give this electronic module through the input low-voltage signal; Thereby control the output of high-voltage signal, but adopt this solution can cause integral vehicle cost to increase, and take limited a series of problems such as arrangement space; Electronic module increases fault rate because extraneous interference or other factors cause malfunctioningly in addition, will directly cause the security of system problem, and the reliability of system is reduced.
Summary of the invention
The purpose of this invention is to provide a kind of battery-driven car ignition lock two-way voltage-operated device; It has avoided environment and the influence of artificial service factor to controller under the prerequisite that realizes identical function, reduced fault rate; Reduce maintenance and use cost, and practiced thrift limited arrangement space.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: it comprises key control shelves 1, high tension supply 2, high drive device 3, electric machine controller 4, low potential source 5, low-voltage driving device 6, car load current consumer 7; High tension supply 2, low potential source 5 are connected with key control shelves 1 respectively; High drive device 3 is connected with high tension supply 2; Electric machine controller 4 is connected with high drive device 3, and low-voltage driving device 6 is connected with low potential source 5, and car load current consumer 7 is connected with low-voltage driving device 6.
The present invention has following beneficial effect: it has avoided environment and the influence of artificial service factor to controller under the prerequisite that realizes identical function, reduced fault rate, has reduced maintenance and use cost, and has practiced thrift limited arrangement space.
Description of drawings:
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the embodiments of the invention principle schematic.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it comprises key control shelves 1, high tension supply 2, high drive device 3, electric machine controller 4, low potential source 5, low-voltage driving device 6, car load current consumer 7; High tension supply 2, low potential source 5 are connected with key control shelves 1 respectively; High drive device 3 is connected with high tension supply 2; Electric machine controller 4 is connected with high drive device 3, and low-voltage driving device 6 is connected with low potential source 5, and car load current consumer 7 is connected with low-voltage driving device 6.
In this specific embodiment when work, be improved to high tension supply with the power supply of the off-load gear ACC of common two-way ignition lock, could control electric machine controller (or DC-DC electric pressure converter) when therefore having only ignition lock to be opened to ACC or ON gear and work; Because the electrokinetic cell direct supply is adopted in the startup of pure electric automobile electrical motor; Therefore originally be used for preferential (the ACC gear of off-load) the off-load effect in the middle of car load that guarantees to light a fire and do not exist, so the current consumer of original ACC gear is incorporated in operating voltage ON (or normal) gear; Other gear of ignition lock remains unchanged.
This specific embodiment has been avoided environment and the influence of artificial service factor to controller under the prerequisite that realizes identical function, reduced fault rate, has reduced maintenance and use cost, and has practiced thrift limited arrangement space.
Embodiment:
As shown in Figure 2, the wiring pin comprises power supply B1 and B2, ACC, and IG1 and IG2, key inserts gear K1 and K2.
The B1 power supply is the low potential source of car load current consumer, and B2 is electric machine controller (or DC-DC electric pressure converter) high pressure control power supply.
ACC is the control output gear of electric machine controller (or DC-DC electric pressure converter).
IG1 is the control output of car load low tension ON shelves; IG2 is the control output of electric machine controller (or DC-DC electric pressure converter) high-tension current ON shelves.
K1 and K2 are the break-make that key inserts shelves.
When key does not insert, the switch access failure.
When key inserted, the K1 of switch and K2 pin were connected, and were used to the state of indicating key to insert.
When key was in the ACC gear, pin B2 and ACC connected, and make electric machine controller (or DC-DC electric pressure converter) obtain working power; Pin K1 and K2 are in on-state.
When key was in the ON gear, pin B1 and IG1 connected, and guaranteed that the car load current consumer obtains working power or control power supply; Pin B2 and ACC connect, and connect with IG2 simultaneously, guarantee electric machine controller controlled power supplys such as (or DC-DC electric pressure converters).
