Abstract

A safety analysis system for wiring, including: a storage unit that stores electric wire-terminal connector correlation information in which each of a plurality of electric wires and a pair of connectors are correlated with each other, terminal connector-function correlation information in which the pair of connectors located at terminals and a function of a device to which the connectors are connected are correlated with each other, and function determination information including a combination of a plurality of functions that are not allowed to be lost at the same time; and a processing unit that matches the electric wire-terminal connector correlation information and the terminal connector-function correlation information when the wire harness is identified, and generates electric wire-function correlation information in which each of the plurality of electric wires and the function of the device are correlated with each other.

First claim

What is claimed is:

1. A safety analysis method for wiring in a wiring structure in which each of a plurality of electric wires belonging to a wire harness is connected to a pair of connectors located at terminals via a relay element, the safety analysis method comprising:
storing:
electric wire-terminal connector correlation information in which each of the plurality of electric wires and the pair of connectors are correlated with each other, terminal connector-function correlation information in which the pair of connectors located at the terminals and a function of a device to which the connectors are connected are correlated with each other, and
function determination information including a combination of a plurality of functions that are not allowed to be lost at the same time;

matching the electric wire-terminal connector correlation information and the terminal connector-function correlation information when the wire harness is identified;
generating electric wire-function correlation information in which each of the plurality of electric wires and the function of the device are correlated with each other;
determining whether or not the combination of the plurality of functions included in the function determination information exists in the generated electric wire-function correlation information; and
evaluating that the wire harness is safe when the combination does not exist.

2. The safety analysis method for wiring according to claim 1 , further comprising displaying the generated electric wire-function correlation information.

3. The safety analysis method for wiring according to claim 1 , further comprising displaying a result of the evaluating.

4. The safety analysis method for wiring according to claim 1 , further comprising:
storing terminal connector-separation requirement correlation information in which the pair of connectors located at the terminals and a separation requirement code are correlated with each other;
matching the electric wire-terminal connector correlation information and the terminal connector-separation requirement correlation information when the wire harness is identified; and
generating electric wire-separation requirement correlation information in which each of the plurality of electric wires and the separation requirement code are correlated with each other.

5. The safety analysis method for wiring according to claim 4 , further comprising:
determining whether or not the separation requirement codes included in the generated electric wire-separation requirement correlation information are identical within a range in which redundancy is required; and
evaluating that the wire harness is safe when the separation requirement codes are identical.

6. The safety analysis method for wiring according to claim 4 , further comprising displaying the evaluation result.

7. The safety analysis method for wiring according to claim 1 , further comprising:
changing a design of the wiring structure based on the evaluation of the wire harness, such that an evaluation result of the changed design indicates that the wire harness is safe.

8. A safety analysis method for wiring in a wiring structure in which each of a plurality of electric wires belonging to a wire harness is connected to a pair of connectors located at terminals via a relay element, the safety analysis method comprising:
storing electric wire-terminal connector correlation information in which each of the plurality of electric wires and the pair of connectors are correlated with each other, and terminal connector-separation requirement correlation information in which the pair of connectors located at the terminals and a separation requirement code are correlated with each other;
matching the electric wire-terminal connector correlation information and the terminal connector-separation requirement correlation information when the wire harness is identified;
generating electric wire-separation requirement correlation information in which each of the plurality of electric wires and the separation requirement code are correlated with each other;
determining whether or not the separation requirement codes included in the generated electric wire-separation requirement correlation information are identical; and
evaluating that the wire harness is safe when the separation requirement codes are identical.

9. The safety analysis method for wiring according to claim 8 , further comprising displaying the evaluation result.

10. The safety analysis method for wiring according to claim 8 , further comprising:
changing a design of the wiring structure based on the evaluation of the wire harness, such that an evaluation result of the changed design indicates that the wire harness is safe.
