Problems solved by technology

[0002] The current automotive ESP fault diagnosis system adopts the method of directly storing the fault code into the specified non-volatile memory address for fault code storage management. This method can only record the diagnosis result of the latest corresponding fault type in one memory byte. , cannot store the historical records of this type of fault diagnosis results, and provide less information for accident repairs, especially for intermittent faults, the previous fault codes may be cleared because the last diagnosis has no faults, which is not conducive to fault repairs and timely elimination of potential safety hazards ; This storage method also causes a waste of system storage resources

Embodiment Construction

[0011] In order to further illustrate the present invention, further describe below in conjunction with accompanying drawing:

[0012] The ESP fault diagnosis system first determines the fault type of the diagnosed fault, and defines its fault code according to the fault type ; Correspond the fault code to the address of a certain byte in the specified storage unit, that is, each fault code in the ESP fault diagnosis system corresponds to a specified storage unit address, which is conducive to simplifying the control program algorithm, code storage, transmission and reading Pick. figure 1 As shown, an example is given to illustrate the correspondence between fault codes and storage addresses. For example, the storage address corresponding to fault code C1411 is $FDED; the storage address corresponding to C1412 is $FDE1; the storage address corresponding to C1413 is $FDE2;

[0013] figure 2 As shown, it is an example of storing fault codes by bits. For the storage unit addre...

Abstract

The invention discloses a vehicle driving safety management system, which is characterized in that a vehicle ESP is adopted to store and manage fault codes, the vehicle can perform driving according to an intention of a driver while the driving stability of the vehicle is ensured, the driving safety of the vehicle is greatly improved, the vehicle ESP fault code storage and management are a mode of defining, storing and reading the fault codes by an ESP fault diagnosis system, the ESP defines the fault codes firstly according to a fault type, and each fault code is in one-to-one correspondence with each byte address in a specified storage unit. The system reliability is improved, nonvolatility and historicality of system diagnosis result storage data can be ensured, and the algorithm is simple, high in efficiency and short in operation period.

Description

technical field [0001] The invention relates to a vehicle running safety management system. Background technique [0002] The current automotive ESP fault diagnosis system adopts the method of directly storing the fault code into the specified non-volatile memory address for fault code storage management. This method can only record the diagnosis result of the latest corresponding fault type in one memory byte. , can not store the historical records of this type of fault diagnosis results, and provide less information for accident repairs, especially for intermittent faults, the previous fault codes may be cleared because the last diagnosis has no faults, which is not conducive to fault repairs and timely elimination of safety hazards ; This storage method also causes a waste of system storage resources. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical vehicl...
