Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance control devices face high demands on resources and computing speed due to the need to perform all safety functions in parallel, making them resource-intensive and costly.
Innovation Solution
The implementation of multiple function modules, each with an evaluation, decision, and control module, allows for dynamic selection and prioritization of safety functions based on sensor data, enabling only necessary functions to be executed, thereby reducing hardware requirements and optimizing resource allocation.

Engineering Contradiction Analysis
1Reliability
If all safety functions are performed simultaneously by the driver assistance control unit, then comprehensive safety coverage is achieved, but hardware resource requirements and processing speed demands increase significantly
Solution Approach 1:
The patent segments the driver assistance control unit into multiple independent functional modules, each responsible for specific safety functions. Each module contains its own evaluation module, decision module, and control module. This segmentation allows the system to activate only the necessary modules for current driving conditions, reducing overall hardware resource requirements while maintaining comprehensive safety coverage when needed.
Solution Approach 2:
The system dynamically selects and activates functional modules based on current driving situations and sensor data. The control module determines which functional modules should be operated at any given time, allowing the system to adapt its resource consumption to actual safety needs. This dynamic operation reduces processing demands during normal conditions while ensuring comprehensive safety coverage when risks are detected.
2Speed
If multiple safety functions are executed in parallel, then response time for safety interventions is reduced, but computing power and processing speed requirements increase
Solution Approach 1:
By dividing safety functions into separate functional modules with dedicated evaluation, decision, and control components, the system can execute only the necessary modules in parallel based on current conditions. This selective parallel execution reduces computing power requirements compared to running all functions simultaneously, while still maintaining fast response times for critical safety interventions.
Solution Approach 2:
The system executes only the necessary safety functions based on current driving conditions rather than all available functions. The control module determines which functional modules should be activated, allowing partial execution of safety functions when full coverage is not needed, thus reducing computing power consumption while maintaining adequate response time for actual safety needs.
