Abstract

The present invention relates to a remote request processing method and a system based thereon, which is intended to minimize the discharge of a low-voltage auxiliary battery that supplies power to an electrical load in response to a remote request in a Software Defined Vehicle (SDV). The method comprises: a step of confirming whether a data processing request related to at least two connected ECUs has been received when data communication is received from a remote request source; a step of determining whether the ECUs need to perform the data processing request; a first transmission step of transmitting the data processing request to the ECUs when it is determined that there is a need to perform the request; and a second transmission step of transmitting data already stored in a function buffer to the remote request source when it is determined that there is no need to perform the request.

Description

Method to handle remote requests and the system for the same An embodiment according to the present invention relates to a remote request processing method and a system according thereto for minimizing the discharge of a low-voltage auxiliary battery (12V or/and 24V) that supplies power to an electrical load in response to a remote request in a Software Defined Vehicle (SDV). Recently, as the transition to Software Defined Vehicles (SDVs) accelerates, vehicle control and inquiry services via smartphones are increasing. Whenever a service is requested for remote control or monitoring of the current vehicle status using a smartphone or tablet, the vehicle system activates a communication domain to transmit commands for internal drive load operations or latest data updates; this wakes up each ECU, thereby increasing current consumption. Even if the drive load required for remote control is currently in a faulty state or the data to be queried remains in the same state as before, unnecessary current may be consumed because communication domain activation and ECU (Electronic Control Unit) wake-up are performed. In addition, the 12V battery may be unexpectedly discharged if there is a vehicle inquiry caused by hacking or abnormally excessive service operation. In other words, while preventive measures such as limiting the number of service uses were discussed at the server level to prevent abnormal remote control services, there is currently no logic to restrict communication domain activation and ECU wake-up within the vehicle to prevent unnecessary consumption of the low-voltage auxiliary battery. FIG. 1 is an example diagram of relationships to explain the concept of responding to a remote request in a vehicle to which the remote request processing method according to the present invention is applied. FIG. 2 is an example diagram of the operation flow according to the remote request processing method according to the present invention. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated and described in the drawings. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. The suffixes "module" and "part" used in this specification are used merely for nominal distinction between components and should not be interpreted as presupposing that they are physically or chemically distinguished or separated, or that they can be distinguished or separated in this way. Terms containing ordinal numbers, such as “first,” “second,” etc., may be used to describe various components, but said components are not limited by said terms. These terms may be used solely in a nominal sense to distinguish one component from another, and their sequential meaning is determined not by such nomenclature but by the context of the description. The term “and/or” is used to include any combination of the multiple items in question. For example, “A and/or B” means including all three cases, such as “A,” “B,” and “A and B.” When it is stated that one component is "connected" or "joined" to another component, it should be understood that while it may be directly connected or joined to that other component, there may also be other components in between. The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, terms such as "comprising" or "having" are intended to specify the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. Furthermore, "unit," "control unit," "control device," or "controller" are merely terms widely used to name devices that control the corresponding function, and do not imply a generic function unit. For example, a device referred to by these names may include a communication device that communicates with other controllers or sensors to control the corresponding function, a computer-readable recording medium that stores an operating system, logic instruct
