Vehicle Input Interface for Immediate Climate Control at Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle input reception systems require the engine to be started and a display unit to activate before allowing operation instructions, leading to delays in adjusting vehicle environments such as temperature, especially in extreme conditions.
Innovation Solution
An input reception system with a first input device that starts quickly and displays recommended operation information based on temperature, allowing immediate action, while a second device starts later but displays detailed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display unit with navigation screen is used as input reception device, then detailed information can be displayed, but it takes longer time to activate and cannot receive operation instructions immediately
Solution Approach 1:
The input reception system is divided into two separate devices: a first input reception device with short activation time for immediate operation input, and a second input reception device with display screen for detailed information display. This segmentation allows each device to specialize in its strength, resolving the contradiction between fast activation and comprehensive information display
Solution Approach 2:
The first input reception device acts as an intermediary that bridges the gap between engine start and full system activation. It provides a simplified interface for essential operations during the transition period before the second device is fully activated, enabling users to input operation instructions without waiting for the complete system to start
2Reliability
If the system waits for display unit activation before accepting input, then system stability is ensured, but user response time is delayed especially in extreme temperature conditions
Solution Approach 1:
The first input reception device is activated in advance before the second device with display screen. This preliminary action allows the system to accept operation instructions immediately after engine start, enabling users to adjust vehicle environment (heating/cooling) without waiting for the main display system to fully activate, thus improving ease of operation while maintaining system stability

AI summary
A system comprising: first and second input reception devices; and a temperature detection unit for detecting a temperature inside a vehicle, wherein the first input reception device includes: a first input reception unit for receiving the input of the operation instruction by being pressed or touched, and including a first display unit for displaying information; and a control unit for controlling the operation of the operation target based on the received input of the operation instruction, a time required to start the second input reception device is longer than a time required to start the first input reception device, and the control unit causes the first display unit to display recommended operation information based on the detected temperature, and performs an operation corresponding to the recommended operation information in response to pressing or touching of the first display unit.
