A part breaks down.This failure is stored in internal random memory by ECU in the form of code, while lighting indicating fault
Lamp, by the system, driver can note automobile and failure occurs, but specific failure then must be logical in Automobile Service Factory
The specific maintenance for crossing maintenance personal just can determine that.It can not lighting or flicker according to malfunction indicator lamp for most of driver
Situation read failure information cannot need special maintenance personal to go to judge, often due to driver where correct failure judgement
Immeasurable loss is caused not in time to the processing of failure.
Currently, vehicle trouble shows that majority relies only on instrument fault indicator light, this present situation can make driving new hand's read failure
Information is difficult, or read failure information but the grade of failure problems can not be judged, processing of the driver to failure
Often result in immeasurable loss.
Invention content
It for driver existing in the prior art set forth above can not accurately judge failure and make a response in time
Problem, and research and design one kind can directly display the information that is out of order by vehicle-mounted multimedia display screen, driver can be easy
Failure judgement and the pure electric automobile fault detection system handled it in time.
The technical solution adopted by the present invention is:
A kind of pure electric automobile fault detection system, spy are characterized in that, include the cell tube with CAN bus both-way communication
Reason system, entire car controller, drive control device and CAN communication module, the detecting system further include control chip, vehicle-mounted more matchmakers
Body display screen and alarm module;Fault message is sent to control chip, the control by the CAN bus by CAN communication module
Coremaking piece is parsed into after failure code and fault level fault message and is shown by vehicle-mounted multimedia display screen, and controls
Chip controls alarm module alarm driver's electric vehicle processed breaks down, and control chip is according to failure code and failure etc.
Grade prompts driver to make the safety that corresponding actions protect electric vehicle by vehicle-mounted multimedia display screen.
Further, the detecting system further includes being connect with control chip, for storing failure code and fault level
Memory module.
Further, the detecting system further includes server and terminal device, and the control chip communicates mould by 4G
Failure code and failure grade information are sent to the server of distal end by block, the server by the failure code received and therefore
Barrier class information is sent to terminal device in real time, and terminal device makes electric vehicle brake by sending instructions to entire car controller
Parking in time.
Further, the control chip is STM32 Series of MCU.
Compared with the existing technology, the present invention apparently has the advantages that:
1, only need to add one control chip, it is at low cost, using vehicle-mounted multimedia display screen can directly observe where
It breaks down and fault level, each failure code corresponds to a failure, can simultaneously pass through failure corresponding with failure code
Vehicle-mounted multimedia display screen is shown.
2, control chip alarms after receiving failure letter code and failure grade information and shows failure, reminds driver's note
Meaning safety.
3, the failure code that maintenance personal can show according to vehicle-mounted multimedia display screen understands fault condition, finds dimension accurately
Point of penetration is repaiied, the promptness of repair is improved.
