Steering Grip Vibration Layout for Richer Driver Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information notification systems using tactile stimuli are limited in the amount and type of information they can convey, primarily relying on the presence or absence of vibration, necessitating a more sophisticated method to enhance notification capabilities.
Innovation Solution
A vehicle information notification device with a pair of left and right grips featuring multiple vibration devices on each, synchronized with operation intervention functions, varying vibration modes, and display devices to provide advanced tactile and visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single vibration device is used to notify the driver, then the device complexity is low, but the quantity of information that can be notified is limited
Solution Approach 1:
The notification system is segmented into multiple independent vibration devices (first vibration device and second vibration device) positioned at different locations on the steering wheel. Each device can be independently activated to convey different types of information, thereby increasing the quantity of information that can be notified without requiring a single complex device
2Adaptability or versatility
If multiple vibration devices are provided on one grip, then more information types can be notified, but the device complexity increases
Solution Approach 1:
Multiple vibration devices are integrated into a single notification system that serves multiple functions: notifying of general vehicle information, operation intervention function status, and different operational states. This multi-functionality approach increases the adaptability and versatility of the system without proportionally increasing complexity, as all devices work together within a unified control framework
3Reliability
If vibration devices are synchronized with operation intervention function, then driver awareness of operations is enhanced, but the device complexity increases
Solution Approach 1:
The vibration devices are synchronized with the operation intervention function to provide tactile feedback to the driver about system status and operations. When the operation intervention function is activated or intervenes in driver operations, the corresponding vibration device provides immediate tactile feedback, enhancing driver awareness and creating a closed-loop feedback system that improves reliability without requiring complex additional hardware
