AUTOSAR ECU State Manager Overview (ECUM)

[@bhuvneswarbajpaeey]

Very good explanation, thanks

Welcome

[@vengetsekar2674]

Thanks for the nice explanation. I have few doubts. If the wake-up source validation is unsuccessful then ECU enters Shutdown state? Could you say a scenario for TTII.

[@electroniccontrolunit9294]

This TTII is present only in fixed ECUM. It is not present in flexible. This protocol is completely based on timer logic and predefined configured sleep modes. As per my understanding using this TTII protocol based on some timer ECU is woken up(if ECU is not woken up for long time) and made into deep sleep state so that power consumption is reduced to the max.

Electronic Control Unit Thanks for the details.

[@isak4354]

Hi your videos are so informative. Keep it up. Plz also if possible one session on Diag module.

[@electroniccontrolunit9294]

Thank you... I will try

[@AutomotiveEngineeringschool]

Thank you for this vedio

[@electroniccontrolunit9294]

Welcome

[@ramaswamy9282]

Please give a session on OS if you possible

[@electroniccontrolunit9294]

I will try

[@boxerboxer4]

Good explanation. Are you going to make presentation about each state of ECU?

[@electroniccontrolunit9294]

Yes I will do it but will take some time

[@boxerboxer4]

Great! I will be waiting for those videos.

[@naveenkumarn4622]

What is the difference between EcuM modes and EcuM States?

[@electroniccontrolunit9294]

As per my understanding there is no difference from functionality perspective.. Usually if you are referring to any states from BSWM module or any other manager module we call states as modes..

[@sairam-ih3mh]

Hi good explanation, does CANSM is same as ECUSM in operational waise?

[@electroniccontrolunit9294]

CanSM relates to state machine related to CAN protocol. ECUM gives us state machine to maintain power in our ECU

[@sairam-ih3mh]

@@electroniccontrolunit9294 ok thank you

[@hirenprajapati7562]

what is the diff bw shutdown targets : ECUStateOff and ECUStateSleep

[@electroniccontrolunit9294]

Off means power off to ECU. SLEEP means small amount of power is still supplied to ECU

[@curiousworld6644]

Tq very very much

[@kannandevadass7601]

Sis its an good initiative and nice videos with good explanation. But I have few doubts in it. How can I reach you to ask??

[@electroniccontrolunit9294]

Thank you. You can mail me at [e-mail]

[@hsaidinsan6345]

Thanks a lot for the effort But there is small issue with your voice, it is so weak

[@electroniccontrolunit9294]

You mean my voice is not clear?

[@hsaidinsan6345]

Electronic Control Unit your voice can barely be heard May be the microphone

[@electroniccontrolunit9294]

I tried hearing it using my headset. I feel my voice is loud only. Can you try hearing with headset?

[@sankethuske6366]

Mam Please do more detailed video

[@electroniccontrolunit9294]

With respect to ECUM I have plans
