Autonomous Driving System Driver Attention Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving systems often issue operation instructions to drivers during critical situations, overwhelming them with information and operations, leading to feelings of urgency and discomfort, which can hinder smooth vehicle travel and decrease driver confidence.
Innovation Solution
The autonomous driving system assesses the driver's attention desire degree and delays the issuance of operation instructions when necessary, using delay processing to avoid issuing them during peak attention situations, and performs assist processing to reduce the attention demand, thereby reducing the driver's workload and improving response accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving system issues operation instructions immediately when needed, then the system responsiveness and safety are improved, but the driver's workload and stress increase when the driver already desires to pay attention to surrounding situations
Solution Approach 1:
The system dynamically adjusts the issuance timing of operation instructions based on the driver's real-time attention state. When the attention desire degree exceeds a threshold, the system delays issuing instructions; when attention is available, instructions are issued promptly. This dynamic adaptation resolves the contradiction between immediate responsiveness and driver workload by making the system behavior flexible rather than fixed.
Solution Approach 2:
The system changes the timing parameter of instruction issuance based on the driver's attention state. By monitoring the attention desire degree and adjusting the issuance timing accordingly (delaying when attention is high, issuing promptly when attention is low), the system optimizes both responsiveness and driver comfort without compromising safety.
2Adaptability or versatility
If the autonomous driving system issues multiple operation instructions simultaneously, then the system can handle complex situations comprehensively, but the driver becomes overwhelmed and cannot perform response operations accurately
Solution Approach 1:
The system segments the issuance of operation instructions by evaluating each instruction against the driver's current attention state. Instead of issuing multiple instructions simultaneously, the system evaluates and issues instructions sequentially based on available driver attention, ensuring each instruction receives adequate processing capacity and the driver can respond accurately to each one.
Solution Approach 2:
The system applies partial action by selectively issuing only those operation instructions that the driver can currently handle effectively. When attention desire degree is high, the system withholds or delays certain instructions rather than issuing all necessary instructions at once, prioritizing response accuracy over comprehensive simultaneous instruction issuance.
3Productivity
If the autonomous driving system issues operation instructions at timing when driver attention is required for surrounding situations, then the system can maintain continuous monitoring and control, but the driver experiences urgency and discomfort
Solution Approach 1:
The system performs preliminary assessment of the driver's attention state before issuing operation instructions. By evaluating the attention desire degree in advance and delaying instruction issuance when attention is already occupied, the system prevents adding to driver stress while maintaining continuous monitoring through the assessment process itself.
Solution Approach 2:
The system continuously monitors the driver's attention desire degree as feedback and uses this information to adjust instruction issuance timing. This feedback loop allows the system to maintain productivity by issuing instructions only when the driver is attentive, while simultaneously reducing driver stress by avoiding instruction issuance during high-attention periods.

AI summary
An autonomous driving system issues an operation instruction to a driver of a vehicle during autonomous driving. The operation instruction is an instruction that makes a request or a proposal to the driver and urges the driver to perform a response operation responding to the request or the proposal. An attention desire degree is a degree of the driver's desire to pay attention to a situation surrounding the vehicle, and an attention event is an event that increases the attention desire degree. A delay condition is that the attention desire degree exceeds a threshold or the attention event exists. When the operation instruction is necessary and the delay condition is satisfied, the autonomous driving system performs delay processing that waits without issuing the operation instruction. When a delay end condition is satisfied after start of the delay processing, the autonomous driving system issues the operation instruction.
