Towing Warning Suppression Switch for Driver Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During towing operations, vehicles equipped with distance and collision warning systems are unable to switch off these warnings, leading to driver distraction and potential safety risks due to continuous alerts, as the systems are automatically activated when the engine is running.
Innovation Solution
A device with a switching mechanism that allows manual control to prevent or suppress collision and distance warnings, featuring a toggle switch with a towing-specific symbol, automatic reset upon ignition or parking, and integration with hazard warning lights to enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distance and collision warning system is automatically activated when the engine is running, then the safety warning function is ensured, but during towing operations the system causes driver distraction and comfort degradation due to continuous false warnings
Solution Approach 1:
The system dynamically adjusts its operational state based on detected conditions. When towing conditions are detected (through sensor signals indicating abnormal operational parameters), the system automatically transitions from active warning mode to suppressed mode, eliminating false warnings while maintaining safety functionality during normal operations
Solution Approach 2:
The system performs self-diagnosis and self-adjustment by monitoring its own operational parameters and automatically determining when it is in a towing state. This self-service capability allows the system to suppress warnings during towing without requiring external intervention while maintaining safety warnings during normal operation
2Ease of operation
If the engine is kept running during towing to enable steering assistance, then the vehicle can be steered, but the distance and collision warning system remains activated causing unnecessary alerts
Solution Approach 1:
The system segments the warning output function from the engine control function. By independently controlling the warning system's operational state based on detected towing conditions, the system can maintain engine running for steering assistance while separately suppressing warning alerts that would otherwise be generated during towing operations
3Ease of operation
If a manual switching means is added to suppress warnings during towing, then driver comfort is improved, but the device complexity increases
Solution Approach 1:
The system uses self-service by automatically detecting towing conditions through monitoring existing sensor signals and operational parameters. This automatic detection eliminates the need for manual switching mechanisms, complex buttons, or additional user interfaces, thereby improving driver comfort without increasing device complexity
Solution Approach 2:
The system uses existing sensors and control units for multiple purposes - both for normal safety warning functions and for detecting towing conditions. This multi-functionality approach allows the system to suppress warnings during towing without requiring dedicated additional hardware or complex switching mechanisms

AI summary
The invention relates to a device 48 and a method for preventing the output of collision warnings 15a and/or distance warnings 15b in motor vehicles 52 with collision warning output devices 14a and/or distance warning output devices 15b, particularly during a towing operation 50, as well as to a vehicle. The device 48 comprises a switching means 10 configured to allow the output of collision and/or distance warnings 15a, 15b in a first state 82 and to prevent collision and/or distance warnings 15a, 15b in a second state 86. Furthermore, the device 48 comprises an actuating means 16 configured to transfer the switching means 10 from the first state 82 to the second state 86 and from the second state 86 to the first state 82 by manual actuation of the actuating means 16.
