Abstract

Provided are a module relay device and a relay method therefor, and more particularly, a module relay device and a relay method therefor which can guarantee independency by removing execution relationships of one or more respective modules by relaying a call among one or more manager modules, one or more application modules and service modules that perform functions of the battery management system in the middle.

Claims

1. A battery management system (BMS) of a vehicle, the BMS comprising:

a module relay device;

one or more manager modules included in an application layer;

one or more application modules included in the application layer; and

one or more service modules included in basic software (BSW),

wherein the module relay device includes;

a request signal receiving unit receiving one or more function call request signals from the one or more manager modules and the one or more service modules; and

a relay unit selecting the modules corresponding to one or more received function call request selecting the modules corresponding to one or more received function call request signals among one or more manager modules, application modules, and service modules and calling the respective selected modules to relay the modules to each other,

wherein the BMS is configured to control charging and discharging of a battery,

wherein one of the manager modules submits a function call request signal to one of the application modules, via the relay unit, to charge and or discharge the battery, and

wherein the module relay device includes a platform abstract layer (PAL) that serves as an Automotive System Architecture (AUTOSAR) runtime environment (RTE).

2. The BMS of claim 1, wherein the relay unit includes one or more call functions corresponding to one or more function call request signals.

3. The BMS of claim 2, wherein the request signal receiving unit includes a first request signal receiving unit receiving a first function call request signal for a first manager module among one or more manager modules to call a first application module among one or more application modules.

4. The BMS of claim 3, wherein the relay unit selects a first call function corresponding to the first function call request signal among one or more call functions, calls the first application module through the first call function, and relays the called first application module and the first manager module to each other when the first function call request signal is received.

5. The BMS of claim 2, wherein the request signal receiving unit further includes a second request signal receiving unit receiving a second function call request signal for a second application module among one or more application modules to call a first service module among one or more service modules.

6. The BMS of claim 5, wherein the relay unit selects a second call function corresponding to the second function call request signal among one or more call functions, calls the first service module through the second call function, and relays the called first service module and the second application module to each other when the second function call request signal is received.

7. The BMS of claim 2, wherein the request signal receiving unit further includes a third request signal receiving unit receiving a third function call request signal for a second service module among one or more service modules to call a third application module among one or more application modules.

8. The BMS of claim 7, wherein the relay unit selects a third call function corresponding to the third function call request signal among one or more call functions, calls the third application module through the third call function, and relays the called third application module and the second service module to each other when the third function call request signal is received.

9. The BMS of claim 1, wherein the one or more application modules includes at least one of a measurement module, an estimation module, a diagnosis module, a calculation module, a communication module, a manager module, and a recording module.

10. The BMS of claim 1, wherein the one or more service modules includes at least one of a system service module, a communication service module, an input/output (I/O) service module, and a memory service module.

11. A module relay method, comprising:

providing a battery management system (BMS) of a vehicle including;

a module relay device including a request signal receiving unit and a relay unit;

one or more manager modules included in an application layer;

one or more application modules included in the application layer; and

one or more service modules included in basic software (BSW),

receiving by the request signal receiving unit, one or more function call request signals from the one or more manager modules and the one or more application modules and the one or more service modules;

selecting, by the relay unit, the modules corresponding to one or more received function call request signals among one or more manager modules, application modules, and service modules and calling the respective selected modules to relay the modules to each other,

controlling, via the BMS, charging and discharging of a battery, and

submitting, by one of the manager modules, a function call request signal to one of the application modules, via the relay unit, to charge/discharge the battery,

wherein the module relay device includes a platform abstract layer (PAL) that serves as an Automotive System Architecture (AUTOSAR) runtime environment (RTE).

12. The module relay method of claim 11, wherein the receiving the one or more function call request signals includes receiving, by a first request signal receiving unit, a first function call request signal for a first manager module among one or more manager modules to call a first application module among one or more application modules.

13. The module relay method of claim 12, wherein the selecting the modules corresponding to one or more received function call request signals includes selecting, by the relay unit, a first call function corresponding to the first function call request signal among one or more call functions, calling the first application modules through the first call function, and relaying the called first application module and the first manager module to each other when the first function call request signal is received.

14. The module relay method of claim 11, wherein the receiving the one or more function call request signals includes receiving, by a second request signal receiving unit, a second function call request signal for a second application module among one or more application modules to call a first service module among one or more service modules.

15.
