Abstract
The utility model relates to a controller configuration error correcting system, including a plurality of controllers that are arranged in same CAN network, its technical essential is: controller quantity is four for the controller I who gathers and send a signal links to each other with being used for the controller II-IV who prepares information respectively. Based on CAN bus network and the integrated diagnostic function of each controller, prevent to lead to controller configuration to reverse owing to assembling or change wrongly, the messenger puts in order the car and is in the fault mode.
Description
Technical field
The utility model belongs to automotive electronics technical field of electric appliances, specifically a kind of controller configuration error correction system.
Background technology
At present, along with developing rapidly of automotive electronic technology, the continuous progress of In-vehicle networking technology, the application of CAN technology is more and more extensive, and simultaneously also more and more perfect based on the vehicle diagnosing system of CAN technology, integrated function is more and more abundanter.Under normal circumstances, automobile is distinguished according to dynamic property, is mainly divided into high power (HP) and low-power (LP), and namely entire car controller is divided into high configuration and low configuration.Along with the development of controller hardware and software platform, the controller of different configuration all applies identical hardware, different software, is namely high configuration or low configuration from can not differentiating controller in appearance.In this case, generally can distinguish high configuration and low configuration from the difference of Part No., Part No. can be attached to controller surface, also can be integrated in controller internal memory, utilizes diagnostic tool to read.In the process that vehicle assembles or changes, apply the controller of same hardware for having different configuration, if workman or personnel's carelessness after sale, do not check Part No. label, wrongly installed controller will be easy to, cause configuration to be put upside down, make vehicle be in limping pattern and malfunction.
Utility model content
The purpose of this utility model is to provide a kind of controller configuration error correction system, based on CAN network and each controller integrated diagnosis function, prevents due to assembling or changes mistake and cause controller configuration to be put upside down, making car load be in fault mode.
The technical solution of the utility model is as follows: this controller configuration error correction system comprises, comprise the some controllers being arranged in same CAN network, its technical essential is: described amount controller is four, is connected respectively for the controller I gathered with send signal with the controller II ~ IV for preparing information.
Utilize a controller to monitor other controller configuration statuses, form a control system, system configuration is simple, is easy to control, improves the stability of Full Vehicle System, avoid the hidden danger brought due to configuration error.When controller is in configuration error state, this system can make car load be in limping pattern, accelerating to lose efficacy, making driver be easy to this problem of perception as occurred.The advantage there is easy discovery, easily solving.Utilize CAN to collect and send configuration information, improve the speed of information transmission, there is reliability, real-time and flexibility.Utilize vehicle diagnostics technology to read each controller state, line control unit initialization operation of going forward side by side, instead of tradition and to repair mode, save the time, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of controller by CAN transmission of configuration information;
Fig. 2 is for utilizing diagnostic equipment Read Controller information and carrying out the initialized flow chart of controller.
Embodiment
Below in conjunction with Fig. 1 ~ 2, describe content of the present utility model in detail by specific embodiment.This controller configuration error correction system comprises the controller I ~ IV being arranged in same CAN network, is connected respectively for the controller I gathered with send signal with the controller II ~ IV for preparing information.Controller II, III, IV are car load power section controller key, and simultaneously for differentiation controller is high configuration or low configuration, Part No. is written in corresponding controller internal memory by supplier.
Detailed process is: each ignition switch rotates in the certain hour of OFF state, implementation 1, controller I can send diagnosis request signal and issue each controller by CAN, requires Read Controller II, III, IV configuration information, namely reads the Part No. of each controller.Implementation 2 afterwards, controller II, III, IV receive signal, immediately the Part No. information of respective storage can be sent to controller I, controller I receives all controller informations, namely need judge that each controller is high configuration or low configuration by Part No. through certain process.When ignition switch is in ON next time, implementation 3, the information after judging to process is dealt in CAN by controller I, and each controller receives configuration information to judge that controller needs the state performed.Concrete decision logic is, when controller I receives the Part No. of identical configuration in process 2, will be configured with valid value afterwards and be sent in bus in process 3, controller II, III, IV can run by normal mode after receiving and being configured with valid value signal; But when controller I receives the Part No. of different configuration in process 2, as existing height configuration has again low configuration information, invalid configuration value can be sent in bus by controller I in process 3, after controller II, III, IV receive invalid configuration value signal, limping pattern and malfunction being entered separately, cannot isotype be accelerated as made car load.In the process being configured confirmation, configuration signal is lost and controller I also can be caused to be transported to put invalid value in CAN, produce to prevent this problem, if take continuous three ignition cycle controller I all to send invalid configuration value in CAN, controller II, III, IV just confirm configuration error, perform limping pattern afterwards, respective storage configuration error diagnosis diagnostic trouble code, also can store the diagnostic trouble code about configuration error with Time Controller I simultaneously always.
As shown in Figure 2, when car load is in limping pattern, first implementation I, utilizes diagnostic equipment to send diagnostic command and reads control I, II, III, IV diagnostic trouble code separately, judged whether configuration error information.When reading configuration error information, implementation II, utilize diagnostic equipment to send configuration information and Part No. that each controller is read in diagnostic command, tester, by contrast, finally judges the controller of different configuration, finds question classification.Then again write with a brush dipped in Chinese ink the process such as software through controller, after finally guaranteeing that controller configuration is correct, need implementation III, utilize diagnostic equipment to send diagnostic command and initialization is carried out to controller I, counter O reset, restart to perform this function.
