Sensor Data Transmission via Relevance-Based Slot Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sensor systems for vehicle collision detection, such as those using PSI5 standards, often require increased current consumption and thermal loads due to transmitting multiple types of sensor data in a single communication slot, leading to higher costs and material requirements.
Innovation Solution
A method where measured values from sensors are transmitted cyclically, with multiple communication slots allocated based on the relevance of detected physical effects, allowing for reduced computational effort, lower energy consumption, and conditional setup of communication channels, thereby minimizing current consumption and thermal loads.

1Productivity
If multiple types of sensor data are transmitted in a single communication slot, then data transmission capability is improved, but current consumption and thermal loads increase
Solution Approach 1:
The patent divides the communication cycle into multiple communication slots (first communication slot for first measured values, second communication slot for second measured values). This segmentation allows different types of sensor data to be transmitted in separate time slots, reducing the current consumption and thermal load compared to transmitting all data simultaneously in a single slot, while maintaining the overall data transmission capability.

3Use of energy by moving object
If communication channels are set up dynamically based on relevance, then energy consumption is reduced, but system complexity increases
Solution Approach 1:
The patent implements dynamic setup and teardown of communication channels based on the relevance of detected physical effects. Communication channels are established only when relevant data needs to be transmitted, and torn down when not needed. This dynamic approach reduces energy consumption while the defined relevance criteria keep the control logic manageable.
Solution Approach 2:
The patent uses cyclic communication where communication channels are periodically set up and torn down based on relevance assessments at different times. This periodic activation pattern reduces overall energy consumption compared to continuously active channels, while the systematic periodic structure keeps the system complexity manageable.

AI summary
A method for transmitting measured values from a sensor, wherein the measured values are transmitted cyclically, wherein at least two communication slots are provided in one communication cycle, wherein a first measured value, which represents a first physical effect detected by the sensor, is transmitted in a first communication slot, and a second measured value, which represents a second physical effect detected by the sensor, is transmitted in a second communication slot, characterized in that the measured value is transmitted in a communication cycle according to a defined relevance of the currently detected physical effect and/or of the measured value.
