Vehicle Driving Assistance Timing for Manual Deceleration Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In situations where autonomous deceleration control is rendered invalid, operators of vehicles may respond late to traffic information, leading to ineffective deceleration due to delayed notification of deceleration requirements.
Innovation Solution
A vehicle driving assistance apparatus that displays traffic information earlier when autonomous deceleration control is invalid, using an electronic control unit to initiate image display at a predetermined invalid-state point in time, which is earlier than the valid-state point, ensuring operators are informed promptly of deceleration requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous deceleration control is rendered invalid, then the operator must manually respond to traffic information, but the operator may respond late leading to ineffective deceleration
Solution Approach 1:
The system performs preliminary action by displaying the first image at an earlier point in time when autonomous deceleration control is invalid. This advance notification gives the operator sufficient time to prepare and respond manually, preventing late responses and ensuring effective deceleration even without automated control.
2Extent of automation
If the autonomous deceleration control is rendered valid, then the system can autonomously decelerate the vehicle, but the traffic information notification can be delayed
Solution Approach 1:
The system dynamically adjusts the notification timing based on the validity state of autonomous deceleration control. When control is valid, notification occurs at a later point; when invalid, notification occurs earlier. This dynamic adaptation ensures both automated operation efficiency and operator awareness are maintained under different control conditions.

AI summary
A vehicle driving assistance apparatus executes a first control to display a first image by a displaying device and a second control including an autonomous deceleration control to autonomously decelerate the vehicle in response to the traffic information. The first image is an image which displays traffic information on a place where a vehicle will move. The vehicle driving assistance apparatus renders the second control valid or invalid, starts to display the first image at a predetermined valid-state point of time in a situation where the second control is rendered valid, and starts to display the first image at a predetermined invalid-state point of time in a situation where the second control is rendered invalid. The predetermined invalid-state point of time is earlier than the predetermined valid-state point of time.
