Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in maintaining wireless data communications when the ignition is off, as existing technologies often rely on costly cellular networks or experience high latency, and there is a need for remote data connectivity for operations such as vehicle system updates.
Innovation Solution
A method and system that allow a vehicle's wireless communications device to operate in station mode when anticipating ignition termination, detect and connect to a wireless access point, and perform data communications, enabling updates to vehicle system modules even when the ignition is off by using a short-range wireless connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular networking is used for remote data connectivity, then data communication capability is maintained, but cost increases and latency increases
Solution Approach 1:
The patent introduces a wireless access point as an intermediary device that bridges the vehicle to the land network. Instead of directly using cellular networking, the vehicle communicates through a Wi-Fi enabled access point (such as a home router), which then connects to the remote server. This intermediary approach allows the vehicle to use lower-cost, lower-latency Wi-Fi communication for remote data connectivity while maintaining reliable data communication capability.

3Use of energy by moving object
If the vehicle ignition is off, then power consumption is reduced, but wireless data communications cannot be performed
Solution Approach 1:
The patent implements preliminary action by detecting anticipatory ignition termination signals before the ignition actually turns off. When such a signal is detected, the system proactively switches the wireless communications device to station mode and establishes connections to available wireless access points in advance. This allows the vehicle to maintain wireless data communication capability even after ignition shutdown, as the station mode operation consumes minimal power while keeping the communication channel open for urgent data transmission.
4Use of energy by moving object
If the wireless communications device operates in station mode after ignition termination, then power efficiency is maintained, but the device must detect and connect to wireless access points autonomously
Solution Approach 1:
The patent implements self-service by enabling the wireless communications device to autonomously perform detection and connection operations in station mode. The device automatically scans for available wireless access points, evaluates their suitability, and establishes connections without requiring manual intervention or high-power processing. This autonomous operation maintains power efficiency while providing the necessary networking capability for ignition-off scenarios.
