Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It is the flow chart of the whole pure electric vehicle control method of one embodiment of the invention shown in Fig. 1, the side of the embodiment
Method includes the following steps：
Step S10：Multiple troubleshooting modes are demarcated, the troubleshooting mode includes limited torque, limit speed, zero torsion
Electricity under electricity, urgent high pressure under square, high pressure, high pressure is forbidden to power on, forbid charging power on and charge it is lower it is electric in it is part or all of；
Troubleshooting mode is reduced to limited quantity by the embodiment, you can complicated and diversified in processing pure electric automobile
Failure simplifies troubleshooting mode.It is preferred that troubleshooting mode includes limited torque, limits electricity under speed, zero torque, high pressure, is tight
Electricity under anxious high pressure forbids high pressure to power on, charging is forbidden to power on and charge the whole in lower electricity, i.e. the embodiment only takes 8 kinds of events
Hinder processing mode, each troubleshooting mode is set as a scalar quantity.
Step S20：Obtain current fault message；
The a variety of sensing mechanisms and controller of pure electric automobile can obtain its corresponding operating parameter, and according to different
Operating parameter obtains corresponding fault message.The fault message such as can be accelerator pedal failure of removal or such as battery temperature
Degree is more than preset value etc..The vehicle electrical control system structure of pure electric automobile is complicated, and electric parts is more, therefore the source of failure is more,
Type is complicated, needs to obtain current specific fault message in step S20.
Step S30：It responds the fault message and sends control instruction, the control instruction pair to the execution unit of vehicle
It answers one or several in the troubleshooting mode.
Whole-control system can respond fault message and send control instruction to the execution unit of vehicle, to carry out at failure
Reason carries out the exclusion of failure and pure electric automobile failure is avoided to aggravate.Control instruction corresponds to one in the troubleshooting mode
It is a or several, and when troubleshooting mode is several, can be opened or closed at each failure therein by gauged modification
Reason mode.
Specifically, handled during a certain failure using single or various faults, it is also necessary to according to specific actual condition and
The failure of accelerator pedal failure has occurred depending on design concept, such as in driving, then the events such as limited torque, limit speed may be used
Hinder processing mode；Charge fault has occurred when for another example charging, then the lower electric treatment mode of charging may be used, that is to say, that certain
The processing of one failure, can according to the powering on of vehicle, charge, the work condition states such as travel and be designed setting.
The whole pure electric vehicle control method of previous embodiment can use single or various faults processing mode, failure
Processing mode is flexible and changeable, and can be changed by scalar quantity, is opened in each stage of the project implementation according to actual conditions
Or corresponding troubleshooting is closed, it operates simple and practicable.

When should be security classes fault level, send electricity under urgent high pressure to the execution unit of vehicle, high pressure is forbidden to power on or forbid charging
The control instruction powered on.When security classes failure occurs, do not consider to load feelings when whole-control system does electric treatment under urgent high pressure
Condition, i.e., do lower electric treatment at once, and battery management system, electric machine controller also respond the instruction of whole-control system at once.
When the fault message of acquisition corresponds to vehicle performance loss class fault level, limit is sent to the execution unit of vehicle
The control instruction of torque, limit speed or zero torque.When vehicle performance loss class failure occurs, whole-control system is in the stipulated time
It is inside handled, battery management system, electric machine controller response instruction still maintain high pressure connection and power output.
When the fault message of acquisition corresponds to normal failure response class fault level, sent to the execution unit of vehicle high
The control instruction of pressure electricity or the lower electricity of charging.When normal failure response class failure occurs, whole-control system is first by driving motor
The high pressures load break such as system, then carry out the high pressure cut-off of battery management system.Previous embodiment is compared to the prior art, hence it is evident that
Troubleshooting process is simplified, and troubleshooting mode is flexible and changeable, in order to cope with complicated and diversified failure, and then can be into
The exclusion of row failure simultaneously avoids pure electric automobile failure from aggravating.
