Abstract

A method of evaluating compatibility of a first system component of a vehicle, the method including providing a database including vehicle platform configuration information including configuration information about two or more vehicle models, wherein each vehicle model includes one or more aspect domains and each aspect domain includes one or more system components. Each system component includes configuration information. At least two system components of two different vehicle models belong to the same aspect domain. The method also includes determining a compatibility result between said first system component and at least one other system component in said vehicle platform by comparing the configuration information of said first system component to the configuration information of said at least one other system component.

First claim

The invention claimed is:

1. A method of evaluating compatibility of a first system component of a vehicle, the method comprising the steps of:
providing a database comprising:
vehicle platform configuration information comprising configuration information about two or more vehicle models, wherein each vehicle model comprises one or more aspect domains, wherein each aspect domain comprises one or more system components, wherein each system component comprises configuration information, wherein each configuration information comprises a set of one or more parameter values;
wherein at least two system components of two different vehicle models belong to the same aspect domain;
wherein at least one of the number of aspect domains of each vehicle model and the number of system components of each aspect domain of said vehicle model is twenty or more;
determining a compatibility result between said first system component and at least one other system component in said vehicle platform by comparing the configuration information of said first system component to the configuration information of said at least one other system component, wherein the set of one or more parameter values in the configuration information of said first system component is compared to the set of one or more parameter values in the configuration information of said at least one other system component to determine when said sets of parameter values have at least a compatible parameter value;
wherein a positive compatibility result is only determined for those of said at least one other system component that is not the same as said first system component;
returning a compatibility result based on when said first system component is determined to be compatible with said at least one other system component and providing said vehicle with said first system component.

2. A method according to claim 1 , wherein said configuration information of said system component comprises context specific vehicle configuration information and/or wherein said configuration information comprises content configuration information.

3. A method according to claim 1 , wherein the step of determining a compatibility result between said first system component and at least one other system component in said vehicle platform comprises using identifiers, to which each set of parameter values is related, to determine which set of parameter values in the configuration information of said first system component to compare to which set of parameter values in the configuration information of said at least one other system component.

4. A method according to claim 1 , wherein the step of determining a compatibility result between said first system component and at least one other system component in said vehicle platform comprises comparing a plurality of sets of parameter values in the configuration information of said first system component to a plurality of sets of parameter values in the configuration information of said at least one other system component to determine when each compared pair of sets of parameter values have at least a compatible parameter value between them.

5. A method according to claim 1 , further comprising a step of determining a compatibility result between the first system component and a system master by comparing a configuration information of said first system component to a configuration information of said system master, wherein a set of parameter values in the configuration information of said first system component is compared to a set of parameter values in the configuration information of said system master to determine when said sets of parameter values have at least a compatible parameter value, and wherein the step of returning a compatibility result is based on when said first system component is determined to be compatible with said at least one other system component and with the system master.

6. A method according to claim 1 , wherein the method is executed locally in the first system component.

7. A method according to claim 1 , wherein the first system component is disabled when the result incompatible is returned.

8. A method according to claim 1 , wherein the compatibility result is stored locally in the first system component until a new compatibility result is acquired.

9. A method according to claim 1 , wherein the method is performed for all system components in a vehicle model and further comprises a step of determining that said vehicle model is compatible when all system components return the result compatible, otherwise determining that said vehicle model is incompatible.

10. A method according to claim 9 , wherein the method is performed prior to a start-up of a vehicle system and incompatibility prevents the start-up of the vehicle system; or wherein the method is performed within a predetermined time interval after a start-up of a vehicle system and incompatibility forces a shut-down of the vehicle system and/or after a start-up of a vehicle system said vehicle system runs with reduced functionality until the method has returned the result compatible.

11. A method according to claim 9 , wherein when any system component does not communicate within a predetermined time interval after being ordered to execute the method, incompatibility of the system component is determined.

12. A method according to claim 9 , further comprising a step of, when the vehicle model is determined to be incompatible, evaluating when there are alternative configurations available in the vehicle model and when so, acquire a next configuration for the vehicle model and repeating the method until compatibility is achieved or until the method has been completed for all configurations of the vehicle model.

13. A method according to claim 1 , wherein said first system component is an electronic control unit.

14. A system for evaluating compatibility of a first system component of one of a vehicle and a vehicle model, the system comprising:
a database comprising: vehicle platform configuration information comprising configuration information about two or more vehicle models, wherein each vehicle model comprises one or more aspect domains, wherein each aspect domain comprises one or more system components, wherein each system component comprises configuration information, wherein each configuration information comprises a set of one or more parameter values;
wherein at least two system components of two different vehicle models belong to the same aspect domain;
wherein at least one of the number of aspect domains of each vehicle model and the number of system components of each aspect domain of said vehicle model is twenty or more;
a processor configured to receive: configuration information of a first system component and configuration information of at least one other system component, and configured to based on said received information determining a compatibility result between said first system component and at least one other system component in said vehicle platform by comparing the configuration information of said first system component to the configuration information of said at least one other system component, wherein the set of one or more parameter values in the configuration information of said first system component is compared to the set of one or more parameter values in the configuration information of said at least one other system component to determine when said sets of parameter values have at least a compatible parameter value; and configured to:
return a compatibility result based on when said first system component is determined to be compatible with said at le
