Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of Korean Patent Application No. 10-2024-0154298 filed on Nov. 4, 2024, which is hereby incorporated by reference as if fully set forth herein. FIELD Examples of the present disclosure relate to a remote request processing method and system for reducing or minimizing the discharge of a low-voltage battery (e.g., 12 volts (V) and/or 24 V) that supplies power to electrical loads based on a remote request from a vehicle (e.g., a software-defined vehicle (SDV)). BACKGROUND The matters described in this Background section are only for enhancement of understanding of the background of the disclosure, and should not be taken as acknowledgment that they correspond to prior art already known to those skilled in the art. An accelerated shift to software-defined vehicles (SDVs) has increased vehicle control and inquiry services through smartphones. Each time a service is requested for remote control and monitoring a current vehicle status using a smartphone or tablet, a vehicle system may enable a communication domain to transfer commands to operate the driving loads in a vehicle or update the latest data, which may wake up each electronic control unit (ECU) and increase current consumption. Even if a driving load required to perform the remote control is currently in a faulty state or data to be queried remains the same as before, enabling the communication domain and waking up ECU may still be required, and thus currents may be consumed unnecessarily. In addition, in a case where there is a vehicle inquiry by hacking or abnormally excessive service behavior, a 12-volt (V) battery may be discharged unexpectedly. In other words, to prevent an abnormal remote control service, at a server end, certain server-side strategies may be configured to limit a number of times of the service requests. However, there is no logic at the vehicle end to limit activation of the communication domain or the waking of the ECUs, which may lead to unnecessary consumption of a low-voltage battery. SUMMARY Examples of the present disclosure aim to address the problems described above. An object of the present disclosure is to provide a remote request processing method and system, which may prevent unnecessary battery consumption by waking up an electronic control unit (ECU) only if necessary after determining first whether a vehicle system needs to transfer a command of a management server to the ECU based on a remote vehicle control/inquiry service request, and prevent a communication domain from being unnecessarily enabled by this ECU wake-up according to the need, thereby increasing the life of a low-voltage battery and preventing and reducing the cost of claims that may be raised due to discharge.
