Steering Wheel Grip Sensor for Pattern-Based Input

The patent replaces the mechanical touch pad system with a sensor-based detection system. Instead of using a physical touch pad that changes position with steering wheel rotation, the invention uses sensors (such as capacitive, resistive, or optical sensors) embedded in the grip portion to detect finger contact positions and movements. This substitution eliminates the problem of position changes while maintaining the ability to perform input operations without releasing the steering wheel.

The patent applies preliminary action by pre-defining specific detection patterns that indicate input operations. The system is programmed with predetermined patterns (such as specific contact positions, movement trajectories, or contact sequences) that distinguish intentional input operations from normal gripping behavior. When the sensor detects a pattern matching these predefined criteria, it triggers an input operation, thereby simplifying the determination process while maintaining ease of operation.

The patent implements self-service by enabling the system to automatically detect and determine input operations through sensor-based pattern recognition. Instead of requiring the driver to manually operate a switch, the sensors continuously monitor the grip portion and automatically identify input operations based on predefined patterns. This self-determination mechanism eliminates the need for manual switch operation while maintaining accurate differentiation between gripping and input operations, thereby reducing driver workload.
