Vehicle Warning System Idle Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle warning systems, such as rearview cameras, fail to provide early warnings of foreign objects in a vehicle's path when the vehicle is idle, as operators are often distracted during pre-driving preparations, leading to potential hazards.
Innovation Solution
A vehicle warning system comprising a sensor and controller that scans the area around the vehicle while it is parked, outputs a warning signal to notification devices before the vehicle is started, using various sensors like image, audio, radar, or ultrasonic sensors, and can communicate with remote sensors to detect foreign objects and provide timely alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rearview cameras are used for object detection, then the system structure is simple, but early warning capability during idle vehicle state is lost
Solution Approach 1:
The system performs object detection and scanning during the vehicle idle state (before the driver starts driving) to identify foreign objects in advance. The controller activates sensors to scan the area around the vehicle and provides warnings before the vehicle is shifted into gear, allowing the driver to be notified of potential hazards during pre-driving preparations.
2Reliability
If the vehicle scans continuously during idle state, then detection reliability improves, but energy consumption increases
Solution Approach 1:
The controller is configured to periodically communicate with the sensor to identify the presence of foreign objects while the vehicle is idle. This periodic scanning approach provides reliable detection capability during the idle period when energy is available, while avoiding continuous operation that would unnecessarily consume energy during active driving when the vehicle is in motion.

AI summary
The present disclosure provides for a vehicle warning system. The warning system includes a sensor configured to detect a presence of a foreign object and a controller in communication with the sensor. The controller is operable to periodically communicate with the sensor to identify the presence of the foreign object while the vehicle is parked. The controller is further operable to output a warning signal in response to the presence of the foreign object. The warning signal is configured to communicate a detection of the foreign object having entered a path of the vehicle during a period while the vehicle is parked.
