Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle start-up systems struggle to accurately determine a driver's intention and vehicle control state, leading to unintended ignition or failure to turn off the engine when the driver is present.
Innovation Solution
A method and device that automatically control vehicle start-up based on a driver's intention and vehicle control state, utilizing modules to check operation conditions, determine control conditions, and transmit signals to the vehicle control unit (VCU) for precise ignition management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic start-up control is implemented based on driver boarding/disembarkation detection, then convenience is improved, but unintended ignition or failure to turn off ignition may occur
Solution Approach 1:
The system performs preliminary detection of driver boarding/disembarkation status before executing ignition control. By detecting seat occupancy and door opening/closing actions in advance, the system prepares for appropriate ignition control while verifying multiple conditions to prevent unintended ignition or failure to turn off ignition.
Solution Approach 2:
The system continuously monitors driver presence through seat sensors and door sensors, using this feedback to dynamically adjust ignition control decisions. The feedback mechanism ensures the system responds accurately to actual driver actions while preventing erroneous ignition control through multiple condition verification.
2Device complexity
If simple boarding detection is used for automatic start-up, then device complexity is reduced, but control precision deteriorates
Solution Approach 1:
The system merges multiple simple detection functions (seat sensor, door sensor, gear position sensor) into a unified automatic start-up control system. By combining these basic sensors and logically integrating their signals, the system achieves precise driver intention detection without requiring complex individual sensing mechanisms.
Solution Approach 2:
Existing vehicle sensors (seat sensors, door sensors, gear position sensors) are utilized for multiple purposes - their primary functions remain intact while they simultaneously contribute to automatic start-up control decisions. This multi-functional use improves detection precision without adding dedicated complex detection hardware.
3Productivity
If automatic start-up is enabled without conditional checks, then productivity is improved, but safety deteriorates
Solution Approach 1:
The system performs preliminary safety checks including gear position verification (must be in P position), door closure confirmation, and seat occupancy detection before enabling automatic start-up. These preliminary actions ensure safety conditions are met before productivity-enhancing automatic control is activated, preventing unintended ignition risks.
Solution Approach 2:
The system continuously monitors safety conditions (gear position, door status, seat occupancy) and uses this feedback to enable or disable automatic start-up functionality. When safety conditions are not met, the feedback mechanism prevents automatic ignition, eliminating harmful factors while maintaining productivity when conditions are appropriate.

AI summary
In a method and device for automatically controlling vehicle start-up based on a driver's intention and a vehicle's control state, the method for automatically controlling vehicle start-up may include checking setting of a vehicle start-up automatic control mode, when the vehicle start-up automatic control mode is activated, determining whether an operation condition of the vehicle start-up automatic control mode is satisfied, when the operation condition is satisfied, determining a first control condition for automatically starting the vehicle's start-up, and when the first control condition is satisfied, transmitting a first start-up control signal for automatically starting the vehicle's start-up to a vehicle control unit (VCU).
