Wireless Push Notification for Autonomous Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous-driving vehicles face challenges in accurately detecting and responding to objects around them, such as pedestrians and traffic signals, which can lead to traffic incidents due to passive sensing methods that lack active notifications.
Innovation Solution
The system employs wireless push notification signals transmitted by objects, including pedestrians and environmental objects, to provide real-time information about their position and motion capability to the autonomous vehicle, allowing it to adjust its locomotive mechanisms accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If passive sensing methods are used to detect objects around the autonomous vehicle, then the vehicle can operate with simpler sensing equipment, but the detection accuracy and response time are insufficient leading to traffic incidents
Solution Approach 1:
The patent introduces wireless push notification signals as an intermediary communication channel between off-vehicle objects (pedestrians, traffic signals) and the autonomous vehicle. These signals actively transmit object information (position, motion capability) to the vehicle, supplementing passive sensing and improving detection accuracy without requiring complex active sensing equipment on the vehicle side.
2Loss of information
If the autonomous vehicle uses only passive sensing, then the system structure remains simple, but it cannot proactively obtain real-time information about surrounding objects
Solution Approach 1:
Instead of the vehicle actively sensing objects (traditional approach), the patent inverts the information flow by having off-vehicle objects actively transmit their information to the vehicle through wireless push notifications. This inversion allows the vehicle to passively receive comprehensive information about object positions, motion capabilities, and other parameters, reducing information loss without increasing vehicle system complexity.
3Speed
If the vehicle responds only after detecting objects through passive sensing, then the control system remains simple, but the response time is delayed increasing traffic incident risk
Solution Approach 1:
The patent implements preliminary action by having off-vehicle objects transmit their information (position, motion capability) to the autonomous vehicle in advance through wireless push notifications. This allows the vehicle's control system to proactively plan and execute avoidance maneuvers before potential conflicts arise, improving response speed without requiring complex real-time sensing and processing systems.

AI summary
A system included and a computer-implemented method performed in an autonomous-driving vehicle are described. The system performs: detecting a wireless push signal transmitted from a signal transmitter accompanied by an off-vehicle passer and received by a signal receiver of the autonomous-driving vehicle, the wireless push signal including information about a motion capability level of the off-vehicle passer, determining a position and a motion capability level of the off-vehicle passer at least based on the wireless push signal, and controlling a locomotive mechanism of the autonomous-driving vehicle based on the determined position and motion capability level of the off-vehicle passer.
