Vehicle Error Shutdown Alerts for Driver Reaction and Reactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to inform drivers about critical error functions, leading to confusion and increased risk of unexpected vehicle shutdowns, especially in electric vehicles, due to insufficient communication and lack of timely information on required driver actions.
Innovation Solution
A method and device that monitor for predefined critical error functions, deactivate the vehicle if no driver action is taken after a standstill is reached, and provide timely information via a display unit about the deactivation period and required actions to prevent reactivation, using a processing unit to manage these processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle is deactivated automatically when a critical error function occurs and the vehicle comes to a standstill, then safety is improved, but driver awareness and understanding of the situation deteriorate due to lack of information
Solution Approach 1:
The system implements feedback by continuously monitoring driver reactions and providing information output about the critical error situation, the countdown timer, and the required driver actions. This feedback loop ensures the driver understands the situation while the automatic deactivation safety mechanism remains in place.
Solution Approach 2:
The system performs preliminary action by starting a countdown timer and providing advance notice to the driver before the actual deactivation occurs. This allows the driver time to react and understand the situation, improving awareness while maintaining safety through the predetermined deactivation protocol.
2Loss of information
If the vehicle provides detailed information about critical error functions and required driver actions, then driver awareness is improved, but device complexity increases due to additional output units and processing
Solution Approach 1:
The system achieves multi-functionality by using existing vehicle output units (display screens, audio systems) for multiple purposes: normal vehicle operation information and critical error warnings. This provides comprehensive driver awareness without requiring entirely new hardware systems.
Solution Approach 2:
The system merges the critical error monitoring function with the existing vehicle control and output systems. The processing unit integrates error detection, timer management, and information delivery through existing infrastructure, reducing overall system complexity while maintaining comprehensive driver information.
3Ease of operation
If the vehicle allows reactivation after a critical error function, then ease of operation is improved, but reliability deteriorates due to risk of unexpected shutdowns
Solution Approach 1:
The system implements dynamic control of reactivation based on real-time monitoring of driver reactions and system state. The reactivation permission is not static but changes dynamically based on whether the driver has taken the required actions and whether the critical error condition has been resolved, balancing ease of operation with reliability.
Solution Approach 2:
The system uses feedback to control reactivation, continuously monitoring whether the critical error function persists and whether required driver actions have been taken. Reactivation is only permitted when feedback indicates the system is in a safe state, preventing unexpected shutdowns while allowing convenient operation when appropriate.

AI summary
A method for operating a vehicle includes monitoring the vehicle for an occurrence of predefined critical error functions, in a case of which, without a predefined reaction of a vehicle driver, it is necessary to deactivate the vehicle and/or to prevent a reactivation of the vehicle after it has come to a standstill. When an occurrence of one of the predefined critical error functions is established, determining whether the vehicle has come to a standstill, and when it has, starting a predefined time period and checking whether the predefined reaction takes place. After the predefined time period, deactivating the vehicle and/or preventing the reactivation of the vehicle when the predefined reaction has not taken place. From a start of the predefined time period, outputting information to the vehicle driver relating to the predefined time period, the deactivating and/or the preventing the reactivation of the vehicle, and the predefined reaction.
