Vehicle Collision Control Using Conditional External Object Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems do not effectively determine collision possibilities with preceding vehicles when vehicle-to-vehicle communication is possible, and they waste processing load by using external object information when the sensor can fully scan its detection area.
Innovation Solution
A vehicle control apparatus that uses sensors to detect objects and receives external object information when the detection area is blocked, allowing it to perform control based on both host-vehicle-object-information and external object-information to enhance collision detection and reduce processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external object information is obtained from external devices, then collision detection accuracy is improved when detection area is blocked, but information processing load increases
Solution Approach 1:
The system dynamically adjusts whether to acquire external object information based on real-time detection conditions. When the sensor detects that an object blocks the detection area, it activates external device communication to obtain additional object information. When no blocking occurs, it relies solely on local sensor data, thereby adaptively optimizing the balance between detection accuracy and processing load.
Solution Approach 2:
The system changes the parameter of information source selection based on detection conditions. It transitions between using only local sensor data and using both local sensor data and external object information, controlled by the blocking condition determination. This parameter change allows the system to optimize performance based on actual operational needs.
2Reliability
If determination of collision possibility is always performed, then safety is improved, but information processing load increases when not necessary
Solution Approach 1:
The system dynamically adjusts the determination process based on communication status. When vehicle-to-vehicle communication is possible, it performs determination using only local sensor data. When communication fails, it switches to a more thorough determination process that includes external object information, thereby dynamically optimizing safety assurance while managing processing load.
Solution Approach 2:
The system uses feedback from the vehicle-to-vehicle communication status to adjust its determination process. Based on whether communication succeeds or fails, it selectively activates different determination pathways, ensuring safety is maintained while avoiding unnecessary processing when communication is available.
3Measurement precision
If vehicle-to-vehicle communication is used, then object information accuracy is improved, but device complexity increases
Solution Approach 1:
The system implements a multi-functional architecture where the sensor unit serves dual purposes: it performs both local object detection and evaluates blocking conditions. This universal design allows the same hardware to support multiple functions, reducing the need for additional specialized devices while maintaining the ability to improve object information accuracy through selective use of external communication.

AI summary
A vehicle control apparatus comprises, a sensor, mounted on a host vehicle, configured to detect an object outside of the host vehicle, and obtain host-vehicle-object-information on the detected object; a receiving device configured to receive external object information on an object detected by an external device outside of the host vehicle from the external device; and a control unit capable of performing a predetermined control based on at least the host-vehicle-object-information. The control unit is configured to perform the control based on the host-vehicle-object-information when a blocking condition is not satisfied, the blocking condition being a condition to be satisfied when a sensor object that is an object detected by the sensor is present at a position where the sensor object blocks a full scan of the sensor; and to perform the control based on the host-vehicle-object-information and the external object information when the blocking condition is satisfied.
