Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forward collision-avoidance assist systems in vehicles are difficult to test under non-collision conditions, posing risks during testing and making it challenging to confirm proper operation without actual collisions.
Innovation Solution
A test mode is implemented to mitigate operating conditions, adjusting detection references and changing operating conditions to ensure the system functions correctly under low collision risk scenarios, using sensors and processors to recognize objects more sensitively and control vehicle operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the forward collision-avoidance assist is operated only when there is a high collision risk, then the system prevents malfunctions under non-collision conditions, but the driver cannot test the system without taking collision risk
Solution Approach 1:
The system dynamically switches between normal operation mode and test mode based on detection results. In test mode, the system temporarily modifies its operating conditions to allow testing without actual collision risk, while maintaining safety through continuous monitoring and dynamic adjustment of detection references
Solution Approach 2:
The system changes detection reference parameters when test mode is activated, allowing the forward collision-avoidance assist to operate under modified conditions that enable testing while maintaining safety. The detection reference is adjusted to improve object recognition sensitivity during testing
2Measurement precision
If the forward collision-avoidance assist operates under strict collision risk conditions, then false activations are prevented, but the system cannot be tested under usual conditions without collision risk
Solution Approach 1:
The system dynamically adjusts its detection reference based on operational mode. During normal operation, strict collision risk conditions are enforced for high measurement precision. During test mode, the system dynamically modifies detection references to improve object recognition while maintaining safety through controlled operating conditions
Solution Approach 2:
The test mode acts as an intermediary state between normal operation and actual collision testing. It provides a controlled environment where the system can be tested under modified detection references without exposing the driver to real collision risk
3Measurement precision
If the detection reference is adjusted to improve object recognition, then the system becomes more sensitive to potential collisions, but false alarms may increase under normal conditions
Solution Approach 1:
The detection reference is dynamically adjusted based on the operational mode. In normal mode, the system uses standard detection references to minimize false alarms. In test mode, the detection reference is adjusted to improve object recognition sensitivity, with the understanding that the system is being tested under controlled conditions
Solution Approach 2:
The system changes detection reference parameters when transitioning to test mode, allowing improved object recognition for testing purposes. The parameter changes are temporary and mode-specific, ensuring that false alarm rates remain controlled during normal operation while enabling sensitive detection during testing

AI summary
A method and apparatus for testing forward collision-avoidance assist are configured to confirm whether forward collision-avoidance assist is properly operated under usual conditions having no collision risk. A method for testing forward collision-avoidance assist of a vehicle includes steps performed by a processor, including: receiving a test mode enter signal; adjusting a detection reference to improve object recognition of the vehicle; changing an operating condition for the forward collision-avoidance assist to operate the forward collision-avoidance assist in a situation in which the vehicle has a low collision risk; and confirming whether the forward collision-avoidance assist is operated, by using the adjusted detection reference and the changed operating condition for the forward collision-avoidance assist.
