Abstract

The present invention relates to a fault information management system and method for implementing fault information management system for a vehicle. The present invention provides a fault information management system for a vehicle comprising: an interface for connecting a fault item; a first memory for storing a fault state; a memory for establishing a management reference for each fault item; a logic which manages fault information and fault history; and a second memory for storing a fault state.

Claims

1. A fault information management system for a vehicle comprising:

an interface, for connecting a fault item, and which connects to each controller of a vehicle;

a first memory for storing a fault state, and which stores fault information occurring in the present time for each fault item;

a memory for establishing a management reference for each fault item, and transmits the reference to a logic;

a logic which manages fault information and fault history according to the management reference for each fault item; and

a second memory which stores the fault information managed by the logic for managing the fault information, fault history together and priority order of the fault information.

2. The system of claim 1, further comprising an external diagnosis tool that displays the information stored in the second memory for storing the fault state.

3. A method for implementing a fault information management for a vehicle comprising the steps of:

detecting a fault for each fault item and recognizing a fault configuration in an interface;

storing fault information occurring in the present time for each fault item in a first memory;

establishing a management reference for each fault item;

transmitting the management reference to a logic which manages a fault in a memory for establishing the management reference for each fault item;

managing a fault state and further information according to the management reference for each fault item depending on the information provided from the first memory for storing the fault state and the memory for establishing the management reference for each fault item in the logic by managing fault information and fault history; and

storing the fault information managed by the logic which manages the fault information and fault history together with priority order information of the fault information in a second memory for storing a fault state.

4. The method of claim 3, wherein the interface for connecting the fault item allows a preset fault-information-related parameter to be placed in a diagnosis function of a specific controller in order to minimize the setting of the fault-information-related parameter.

5. The method of claim 3, wherein information about whether there is a fault in the present time, information about whether there was a fault in the past time, and a fault configuration are stored in real time in the first memory.

6. The method of claim 3, wherein the second memory for storing the fault state stores information transmitted from the logic wherein basic fault information, a fault state, a counter for determining a fault and controller configuration information are stored in the second memory depending on the fault occurrence order, and transmits the stored information to an external diagnosis tool so as to be displayed thereon.

7. The method of claim 3, wherein when the management reference for each fault item is to be established by a controller developer, the memory for establishing the management reference for each fault item stores the established management reference in the logic, and an initial value of a counter for determining a fault, a fault lamp operating mode and a critical value for displaying a fault are stored as the management reference.

8. The method of claim 3, wherein the logic compares fault information for the past fault history with the present state, manages them, and transmits the comparison result to the second memory for storing the fault state.
