Reverse Path Support Control With Driver Suggestion Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reverse support apparatuses require a driver's explicit consent operation for reverse support control, leading to missed opportunities when the driver is unaware of the need, especially in situations where the control is available.
Innovation Solution
A reverse support apparatus that autonomously suggests and executes reverse support control based on vehicle conditions and driver consent, using sensors and path storage to determine when the control is necessary and displays a suggestion screen for driver approval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional apparatus requires an explicit consent operation for reverse support control, then the driver has control over when the feature is used, but the driver may not recognize when to perform the consent operation, causing missed opportunities to execute reverse support control
Solution Approach 1:
The system performs preliminary analysis of the situation around the vehicle and backward path to determine when reverse support control is appropriate, then proactively presents a suggestion screen to the driver before the driver needs to manually initiate the consent operation. This preliminary action ensures the driver is informed of available opportunities to use reverse support control.
Solution Approach 2:
The system provides feedback to the driver by displaying a suggestion screen that informs the driver when reverse support control is available and appropriate. This feedback mechanism bridges the information gap that causes drivers to miss opportunities, while still requiring driver acknowledgment to maintain control.
2Productivity
If the reverse support control is executed frequently based on various situations, then the utility and helpfulness of the system increases, but the driver may feel troubled or overwhelmed by excessive suggestions
Solution Approach 1:
The system applies different qualities of suggestion presentation based on the specific situation. By evaluating multiple conditions (situation around vehicle, backward path characteristics, vehicle state), the system selectively presents suggestions only when they are truly appropriate and useful, rather than uniformly in all scenarios. This localized application of suggestions maintains utility while avoiding driver frustration.
Solution Approach 2:
The system uses partial action by not suggesting reverse support control in every possible scenario, but only in specific situations where it is genuinely beneficial. The multiple condition checks ensure suggestions are made selectively rather than excessively, balancing availability with driver comfort.

AI summary
A reverse support apparatus comprises a storage device in which a forward path passed by a vehicle when the vehicle travels forward is stored, and a controller configured to be able to execute a reverse support control for the vehicle to travel backward along the forward path. The controller makes a suggestion to a driver of the vehicle to execute the reverse support control, when it is determined that a suggestion condition is satisfied based on a situation around the vehicle or a backward path passed by the vehicle when the vehicle travels backward. The controller executes the reverse support control when the driver consents the suggestion.
