Steering Wheel Horn Triggering with Force-Sensing Wake-Up Control

The patent applies parameter changes by using multiple force transducers to measure force values in different directions and combining these measurements to determine the total actuating force. This allows the system to distinguish between accidental contacts (which typically apply force in limited directions) and intentional horn activation (which applies force from multiple directions), thereby improving reliability while maintaining ease of operation.

The patent implements partial action by requiring that force values from multiple transducers exceed respective thresholds before triggering the horn. This partial threshold-based approach prevents accidental activation while ensuring intentional pressing reliably triggers the horn, resolving the contradiction between ease of operation and triggering reliability.

The patent implements periodic action by having the electronic evaluation system evaluate force values at discrete moments when threshold values are exceeded, rather than continuously monitoring. The system activates the acoustic output only when force values from multiple transducers exceed their respective thresholds, which occurs periodically during intentional horn activation, thereby reducing energy consumption while maintaining reliable triggering.

The system uses the force transducers to automatically detect when activation conditions are met, eliminating the need for continuous electronic monitoring. The transducers self-generate signals when force thresholds are exceeded, and the evaluation system processes these self-triggered events, reducing overall energy consumption while maintaining reliable triggering.

The patent applies segmentation by dividing the force measurement task among multiple force transducers positioned at different locations and orientations. Each transducer measures force in a specific direction, and the electronic evaluation system combines these segmented measurements to determine the total actuating force, improving measurement precision while managing device complexity through modular sensor placement.

The patent implements universality by using the same type of force transducer for multiple measurement purposes - each transducer not only detects force magnitude but also provides directional information when combined with others. This multi-functional use of identical components improves measurement precision without proportionally increasing device complexity.
