Vehicle Key Input Mapping for In-Car Game Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle infotainment systems require users to purchase a game controller, which is inconvenient for elderly and children, and the pairing process is complex.
Innovation Solution
Utilize a vehicle key as a game operation device by storing a correspondence relationship between button operation signals and vehicle game commands, allowing automatic connection without separate user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a purchased game controller is connected to the vehicle central control system, then game operation functionality is achieved, but user expenses increase and device complexity increases
Solution Approach 1:
The vehicle key is transformed from a single-function remote control device into a multi-functional device that can both control vehicle operations and serve as a game controller. The controller maps vehicle key button operations to both vehicle control commands and game commands, enabling the same physical device to perform multiple functions without requiring additional hardware.
Solution Approach 2:
The patent merges the vehicle key and game controller into a single integrated device. Instead of requiring separate devices for vehicle control and gaming, the system combines these functions by detecting button operations from the vehicle key and routing them to appropriate game commands based on the current operating mode.
2Adaptability or versatility
If a purchased game controller is connected to the vehicle central control system, then game operation functionality is achieved, but user expenses increase
Solution Approach 1:
The vehicle key is transformed from a single-function remote control device into a multi-functional device that can both control vehicle operations and serve as a game controller. The controller maps vehicle key button operations to both vehicle control commands and game commands, enabling the same physical device to perform multiple functions without requiring additional hardware.
Solution Approach 2:
The system utilizes the vehicle key that the user already possesses and must have for vehicle operation, eliminating the need to purchase additional equipment. The existing vehicle key's button operations are repurposed to control games, making the system self-sufficient and avoiding extra expenses.
3Ease of operation
If the vehicle key and vehicle are connected without separate user operation, then ease of operation is improved, but automation extent increases requiring system complexity
Solution Approach 1:
The system automatically detects when the vehicle key is present and active, and autonomously switches between vehicle control mode and game mode based on the operational context. This automatic mode switching eliminates the need for manual connection or pairing operations while maintaining system control through intelligent detection of the key's presence and button press patterns.
Data Source
AI summary
A vehicle infotainment system includes a memory and a controller. The memory stores a correspondence relationship between a button operation signal and a vehicle game command. The controller receives the button operation signal transmitted from a vehicle key, where different buttons may transmit different button operation signals, determine whether a vehicle is in a game mode, determine whether a state of the vehicle and a state of the vehicle key each satisfy a preset condition in response to determining that the vehicle is in the game mode, and determine, in response to determining that the state of the vehicle and the state of the vehicle key each satisfy the preset condition, the vehicle game command corresponding to the received button operation signal to operate a vehicle game based on the correspondence relationship between the button operation signal and the vehicle game command stored in the memory.
