Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advanced driver-assistance systems (ADAS) and autonomous driving technologies face challenges in effectively communicating with drivers, particularly in critical situations, as conventional alerts like seat vibrations or visual warnings can be ignored or misunderstood, leading to delayed reactions and potential safety issues.
Innovation Solution
The implementation of a smart glove with actuators that can contract or expand to influence a driver's grip on the steering wheel, providing direct and intuitive control adjustments based on the vehicle's operational response to autonomous control signals, thereby reinforcing or intervening in the driver's actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional alerts like seat vibrations or visual warnings are used to communicate with drivers, then the communication method is simple and easy to implement, but the driver reaction time is delayed and the alerts can be ignored or misunderstood
Solution Approach 1:
The smart glove acts as an intermediary device between the autonomous control system and the driver. It translates autonomous control signals into tactile feedback through grip modulation on the steering wheel, providing intuitive physical communication that the driver cannot ignore while maintaining system simplicity
Solution Approach 2:
The system replaces conventional mechanical alert methods (seat vibrations, visual warnings) with a more direct mechanical interaction through the smart glove that modulates the driver's natural grip on the steering wheel, creating immediate tactile feedback that requires no driver interpretation
2Reliability
If the smart glove applies strong influential control to the driver's grip, then compliance with autonomous control maneuvers is improved, but the driver may experience excessive intrusion or loss of manual control
Solution Approach 1:
The smart glove dynamically adjusts the level of influential control applied to the driver's grip based on real-time feedback from the autonomous control system. The grip modulation varies in intensity and duration to match the specific maneuver requirements, providing compliance enhancement without excessive intrusion
Solution Approach 2:
The system continuously monitors the driver's grip strength and the autonomous control system's operational response, using this feedback to adjust the smart glove's influential control in real-time. This closed-loop control ensures compliance while preventing loss of manual control by maintaining appropriate control levels
3Loss of information
If the smart glove provides direct and intuitive control adjustments, then communication with the driver is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The smart glove integrates multiple functions into a single device: it serves as a wearable sensor for grip detection, an actuator for grip modulation, and a communication interface between the autonomous system and driver. This multi-functionality reduces the need for separate systems while maintaining effective communication
Solution Approach 2:
The smart glove achieves effective communication by modulating physical parameters of the driver's grip (force, duration, timing) rather than requiring complex electronic interfaces. These parameter changes in the mechanical domain are simpler to manufacture and more intuitively understood by the driver
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances driver understanding and reaction time by directly influencing the steering wheel grip, reducing latency and improving compliance with autonomous control maneuvers, making the driving experience more enjoyable and safer by providing a more direct and less intrusive form of communication.
Implementation Method 1
the smart glove comprises an actuator adapted to at least one of contract and expand in response to stimuli. In some embodiments, the at least one of the contraction and expansion of the actuator causes at least one of increasing strength of the driver's grip on the steering wheel, decreasing strength of the driver's grip on the steering wheel

AI summary
Systems and methods are provided for influential control over a driver's hand(s) that grip a vehicle's steering wheel. Upon issuing an autonomous control signal to control motive operation of the vehicle, an autonomous control system of the vehicle may further reinforce the application of the autonomous control signal by inducing the driver's hand(s) to grip/increase grip strength on the vehicle's steering wheel or by releasing the grip/decreasing grip strength on the vehicle's steering wheel. Moreover, the increasing/decreasing of the driver's grip may alternatively, or in addition to the reinforcement aspect, induce augmentative or intervening action(s)/behavior(s) by the driver.
