Platooning Vehicle Message Scheduling for Real-Time Error Detection

The patent segments the communication process by introducing a scheduler that divides message transmission into scheduled time slots for different vehicles. This segmentation allows each vehicle to transmit only its own information at its designated time, eliminating the need to store and transmit information about all other vehicles, thus reducing memory requirements while maintaining communication reliability through structured scheduling.

The patent introduces a scheduler as an intermediary component that manages message transmission timing and sequence. The scheduler receives information from vehicles, determines the transmission order based on scheduled information, and coordinates transmission times. This intermediary enables reliable communication without requiring vehicles to store comprehensive information about all other vehicles, as the scheduler handles the coordination and timing.

The patent implements a feedback mechanism where the determiner checks whether received messages correspond to scheduled transmission times. When a message is lost or contains an error, the system detects the discrepancy between expected and received messages, triggers a retransmission request, and updates the transmission schedule accordingly. This feedback loop ensures real-time effectiveness by quickly identifying and correcting transmission failures without waiting for the next fixed period.

The patent introduces dynamic adjustment to the fixed transmission period by allowing retransmissions at unscheduled times when errors or losses are detected. The scheduler can modify transmission timing based on real-time conditions, such as requesting retransmission of lost messages or adjusting the order of transmission. This dynamic approach maintains the simplicity of scheduled timing while enabling real-time correction of transmission failures.
