Collision Avoidance Steering Alerts for Earlier Driver Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle collision avoidance assist systems often fail to prompt drivers to initiate collision avoidance maneuvers early enough, leading to potentially unsafe collisions due to late recognition of the need for steering maneuvers.
Innovation Solution
A vehicle collision avoidance assist apparatus that includes an electronic control unit to detect potential collisions and notify drivers through visual and auditory cues, guiding them on necessary steering maneuvers to avoid objects by displaying images and providing alerts, ensuring timely recognition and execution of collision avoidance steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle collision avoidance assist apparatus starts applying assist steering torque only when the driver starts carrying out steering wheel maneuvering, then the system applies less assist steering torque overall, but the driver needs to carry out great collision avoidance steering wheel maneuvering at late timing which may not safely avoid collision
Solution Approach 1:
The system provides preliminary notification to the driver before collision risk becomes critical, prompting the driver to initiate steering maneuvering earlier. The notification is displayed when the own vehicle may collide with an object ahead, giving the driver advance warning to start collision avoidance steering maneuvering before the situation becomes urgent.
Solution Approach 2:
The system continuously monitors the surrounding situation using the surrounding information detection apparatus and provides feedback to the driver through notification display. This feedback loop allows the driver to understand the collision risk and respond appropriately, improving the timing and effectiveness of collision avoidance maneuvers.
2Ease of operation
If the driver does not recognize the necessity of carrying out collision avoidance steering maneuvering, then the driver may not initiate the maneuver in time, but the system needs a way to prompt the driver without causing excessive alarm
Solution Approach 1:
The notification display serves as an intermediary between the surrounding information detection apparatus and the driver. It translates detected collision risks into comprehensible visual information that prompts the driver to initiate collision avoidance steering maneuvering, bridging the gap between system detection and driver action.
Solution Approach 2:
The notification display uses visual indicators including color changes to communicate collision risk to the driver. The display shows images with different colors and patterns to indicate the necessity and urgency of collision avoidance maneuvers, making the information easily recognizable and actionable.

AI summary
A vehicle collision avoidance assist apparatus executes a collision avoidance steering maneuvering assist process of applying a steering force to an own vehicle to assist a collision avoidance steering maneuvering carried out by a driver when there is a probability that the own vehicle collides with an object ahead of the own vehicle, and the driver carries out the collision avoidance steering maneuvering to steer the own vehicle to avoid a collision of the own vehicle with the object. The apparatus notifies the driver of a necessity of carrying out the collision avoidance steering maneuvering when determining that there is the possibility that the own vehicle collides with the object ahead of the own vehicle.
