Vehicle Power Control Apparatus Centralizing Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles with various installed devices face challenges in stabilizing power supply, as devices often require different power ratings, leading to inefficiencies and increased costs due to the need for individual power stabilizing circuits in each device.
Innovation Solution
A power control apparatus that includes a communication unit, determination unit, and application controller to receive and interpret power setting requests via a CAN network, determining the appropriate power condition (IGN1, IGN2, ACC, ST, B+, or OFF) and regulating power from a battery and alternator supply to match each device's requirements, eliminating the need for separate power stabilizing circuits in each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual power stabilizing circuits are installed in each device, then power supply stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent consolidates multiple individual power stabilizing circuits into a single centralized power control apparatus. This apparatus receives power from the vehicle's power supply system and distributes regulated power to multiple devices simultaneously, eliminating the need for separate stabilizing circuits in each device while maintaining power supply stability.
Solution Approach 2:
The power control apparatus is designed as a universal power management system that can serve multiple different devices with varying power requirements. It implements power conditioning and distribution functions for the entire vehicle electronics system rather than being device-specific, reducing overall system complexity.

3Device complexity
If centralized power control is implemented, then device complexity is reduced, but power control precision may worsen
Solution Approach 1:
The power control apparatus acts as an intermediary between the vehicle's power supply system and the connected devices. It includes power input terminals for receiving power and power output terminals for distributing regulated power, with internal circuitry that conditions and stabilizes the power before distribution, ensuring precise power delivery despite centralized control.
Data Source
AI summary
A power control apparatus, a vehicle having the same, and a method of controlling the vehicle are provided. The power control apparatus includes a communication unit that is configured to receive a request message related to a power setting via a communication network in a vehicle and a determination unit that is configured to determine a power condition based on the request message related to the power setting. Additionally, an application controller is configured to execute an application of power supplied from at least one among a battery and an alternator power supply based on a result of the determination.
