Solution Overview
Problem
Vehicles, especially plug-in hybrid electric vehicles, lack intuitive and remote access to their systems, limiting user interaction and requiring specialized equipment for diagnostics, which increases costs and reduces service capability.
Innovation Solution
A vehicle wireless information system that includes an onboard computer and external access points for remote wireless access and control of vehicle functions, allowing operators and technicians to interact with systems via home networks, mobile devices, or the Internet, enabling remote operation and diagnostics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle systems are powered by a 12-volt lead acid battery and systems are disabled to ensure reliable starting, then vehicle starting reliability is improved, but user access to vehicle systems is limited and interaction is restricted
Solution Approach 1:
The patent introduces a wireless communication system as an intermediary between the user and vehicle systems. The system includes a wireless transceiver coupled to the vehicle computer, allowing users to access and control vehicle functions remotely through wireless devices without requiring physical presence or disabling safety protocols. This mediator enables interaction while maintaining the integrity of the starting system.
Solution Approach 2:
The patent replaces traditional mechanical/physical interaction mechanisms (keys, buttons, physical access to vehicle components) with wireless electronic communication. The wireless transceiver system substitutes physical presence requirements with electromagnetic signal transmission, allowing users to access vehicle systems remotely without mechanical intervention that would compromise starting reliability.
2Measurement precision
If service personnel require specialized equipment to access vehicle diagnostics, then diagnostic accuracy is improved, but capital costs increase and service capability is reduced due to limited equipment availability
Solution Approach 1:
The patent creates a universal wireless access system that can be accessed by multiple users and devices simultaneously through standard wireless communication protocols. The vehicle computer with wireless transceiver capability serves as a multi-functional interface that replaces specialized diagnostic equipment, allowing any wireless-enabled device to access vehicle diagnostics without requiring proprietary tools. This universal approach maintains diagnostic accuracy while eliminating equipment complexity barriers.
Solution Approach 2:
The patent effectively creates a virtual copy of specialized diagnostic equipment functionality through software-based wireless communication. Instead of requiring physical specialized hardware, the system replicates diagnostic capabilities through wireless data transmission and processing, allowing service personnel to access vehicle diagnostics using standard wireless devices rather than expensive specialized equipment.
3Use of energy by moving object
If vehicle systems are accessed only during vehicle operation through non-intuitive interfaces, then battery power consumption is reduced, but user interaction quality deteriorates due to lack of keyboard or mouse access
Solution Approach 1:
The patent segments the user interaction function from the vehicle operation context. The wireless transceiver system allows users to access and control vehicle functions remotely when the vehicle is off, separating the interaction capability from the operational state. This segmentation enables full-featured user interfaces (keyboard, mouse, touchscreen) to be accessed remotely without requiring the vehicle's main systems to be powered on, thus maintaining energy efficiency while improving interaction quality.
