Description
Technical field
The invention belongs to electric vehicle engineering field, and in particular to a kind of drive mode electrification control method.
Background technology
Need to charge to battery in new-energy automobile, conventional art not corresponding prison when being charged to battery
Geodesic structure, so as to can not be effectively and timely to going up electric control under drive mode, so applicability and practicality are restricted.
The content of the invention
It is an object of the invention to provide a kind of strong applicability and be advantageous to improve electricity on the stable drive mode of vehicle use
Control method.
The technical scheme for realizing the object of the invention is a kind of drive mode electrification control method, including KEYON sensings
Device, the controller being connected with the KEYON signal transducers and the CAN being connected with the controller, including
Following steps；
Step A, KEYON signal transducer induced signal, i.e. signal are height, and set initialization time by controller；
Step B, controller are detected and judged to the communications status and battery status information of CAN,
And determined whether according to judged result to electric on high-tension electricity；
Step C, controller is to total positive relay, preliminary filling relay in high-tension electricity power up and always negative relay is carried out
Control, sequentially enter high pressure precharge and high pressure power-up state；
Step D, after the completion of upper electricity, state that controller enters according to the input-signal judging vehicle of driver, completion
Upper electric control.
In stepb, when the communications status of CAN is " 1 ", it is judged as not filling perhaps to electric on high-tension electricity, when
When the communications status of CAN is " 0 ", controller judges battery status information, when battery failures are not belonging to " level Four event
During barrier ", it is judged as filling perhaps to high-tension electricity power on operation, wherein " 0 " represents that CAN communication state is normal, " 1 " represents CAN communication shape
State failure, level Four failure are to need the battery failures of broken height pressure.
In step C, controller makes always to bear relay closure, while preliminary filling relay closes, and shape is pre-charged into high pressure
State, after high pressure pre-charge state is completed, controller makes total positive relay closure, while preliminary filling relay disconnects, into driving
High pressure power-up state.
In step D, when the input signal of driver is KEYSta signals and effective brake signal, vehicle enters " accurate
It is standby " state；When the KEYON signals of driver's input are low, controller control, which arranges, enters power-down state.
The present invention has positive effect：The present invention can effectively realize control electric in high pressure under driving states, can be with
Prevent from carrying out high pressure when CAN communication failure or battery need disconnected high voltage fault it is electrically operated, so as to effectively ensure vehicle
Upper electric stability and security, strong applicability and practicality is good.
Brief description of the drawings
In order that present disclosure is more likely to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail, wherein：
Fig. 1 is the method and step schematic diagram of the present invention.
Embodiment
(embodiment 1)
