Vehicle Communication System Targeted Message Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for vehicles lack an efficient mechanism to target-specifically communicate messages to individual vehicles, leading to difficulties in conveying important information such as pull-over signals, especially in situations where traditional methods like honking or visual signals may be misunderstood or missed.
Innovation Solution
A system that utilizes a video stream to display multiple vehicles within a field-of-view, allowing users to select and communicate specific messages to targeted vehicles through a wireless network, using a digital model representation and unique vehicle identifiers for accurate message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication methods (honking, visual signals) are used to convey messages to other vehicles, then the communication can be initiated, but the message may be misunderstood or missed by the target driver
Solution Approach 1:
The patent introduces a communication system with display devices in both sending and receiving vehicles as an intermediary. The message sender can visually select the target vehicle from multiple candidates on their display, and the target vehicle's display shows the received message content, ensuring accurate transmission and understanding of the intended message without relying on ambiguous traditional signals.
Solution Approach 2:
The system implements feedback by displaying received messages to the target driver and enabling two-way communication. The target vehicle can send acknowledgment or response messages back to the original sender, creating a closed-loop communication system that confirms message receipt and understanding, thereby improving reliability and reducing information loss.
2Ease of operation
If a driver wants to communicate with a specifically selected vehicle, then targeted communication is possible, but it is difficult to identify and select the specific vehicle among multiple vehicles
Solution Approach 1:
The patent uses visual copies or representations of vehicles (displayed images or icons on the screen) instead of requiring direct physical identification. The sender's display device shows visual representations of detected vehicles, allowing the driver to easily select the target by viewing these simplified visual copies rather than manually searching for or physically approaching the actual vehicle.
Solution Approach 2:
The display device acts as an intermediary between the driver and the actual vehicles. It processes complex vehicle identification data (coordinates, identifiers, images) and presents it in an easily selectable format on screen, simplifying the selection process while managing the underlying complexity of vehicle identification and tracking systems.
3Reliability
If a traffic officer follows a suspect vehicle with flashlights to indicate pull-over signal, then the signal can be conveyed, but the traffic officer may miss the suspect vehicle or the driver may not understand the signal instantly
Solution Approach 1:
The patent replaces the mechanical/physical signal system (flashlights, hand gestures) with an electronic communication system. Messages are transmitted digitally through the communication system and displayed on the target vehicle's screen, providing clear, unambiguous text or visual signals that can be instantly understood, eliminating the delays and ambiguities of physical signaling methods.
Solution Approach 2:
The system provides immediate feedback by displaying the received message on the target vehicle's display device, confirming to the driver that the signal has been received. The driver can also send acknowledgment messages back, creating instant confirmation of understanding and reducing the time needed for signal comprehension compared to traditional methods where understanding is uncertain.

AI summary
Various aspects of a system and method for communication of a message to a vehicle are disclosed herein. The system comprises one or more circuits in an electronic control unit (ECU) of a first vehicle that is communicatively coupled to a display device. The one or more circuits in the ECU are configured to receive a video stream and control display of a plurality of image frames in the video stream on the display device. Vehicle information of one or more vehicles, included in an image frame of the plurality of image frames, is received from the one or more vehicles via a wireless network. A first input corresponding to a selection of a vehicle from the one or more vehicles included in the image frame, is received. Vehicle information associated with the selected vehicle is identified. A second input that corresponds to a selection of an information item to be communicated to the selected vehicle, is received. The selected information item is communicated to the selected vehicle.
