Automated Driving Obstacle Recognition Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems face challenges in consistently recognizing obstacles, leading to interruptions in automated driving mode and reduced convenience for users, as the system may incorrectly identify obstacles that do not affect vehicle operation.
Innovation Solution
An automated driving system that includes an electronic control unit capable of recognizing obstacles, creating traveling plans, and controlling the vehicle using actuators, with a user input option to overwrite obstacle recognition results, allowing users to exclude obstacles that do not impact driving, thereby maintaining automated mode operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automated driving system relies solely on system-side obstacle recognition, then the system maintains operational control, but automated driving is frequently interrupted and switched to manual driving when recognition fails
Solution Approach 1:
The patent introduces a display device as an intermediary between the obstacle recognition system and the driver. The display presents recognized obstacles to the driver, enabling them to verify and correct recognition results. This intermediary allows the system to maintain automated operation while incorporating human judgment to improve recognition accuracy and prevent unnecessary mode switches.
2Reliability
If the system switches to manual driving when obstacle recognition is uncertain, then safety is maintained, but the convenience and continuity of automated driving deteriorates
Solution Approach 1:
The system enables the driver to perform self-verification of obstacle recognition through the display device. When the driver confirms an obstacle does not require action, they can directly instruct the system to continue automated driving without mode switching. This self-service approach allows the driver to quickly resolve recognition uncertainties while maintaining automated operation, reducing time loss and preserving driving continuity.
3Measurement precision
If the system requires user input to correct obstacle recognition, then recognition accuracy improves, but system complexity and user burden increases
Solution Approach 1:
The patent implements a simplified correction mechanism where the driver can provide partial input (confirmation or correction of specific obstacles) rather than requiring comprehensive system reconfiguration. The display device shows recognized obstacles, and the driver只需 provide minimal input to correct errors, avoiding the need for complex system changes while still improving recognition precision.

AI summary
An automated driving system includes at least one electronic control unit configured to: recognize at least one obstacles around a vehicle, based on ambient surroundings of the vehicle; create a traveling plan of the vehicle, based on the ambient surroundings and a result of recognition of the at least one obstacles; control the vehicle using an actuator installed on the vehicle, based on the traveling plan; and perform, according to input from a user of the vehicle, overwriting operation to change the result of recognition of the at least one obstacles used for creation of the traveling plan.
