Solution Overview
Problem
Existing vehicle systems face limitations in efficiently providing multiple driver assistance functions due to the complexity and error susceptibility of distributing control functions across various sensors and control units, leading to increased costs and material requirements.
Innovation Solution
A vehicle environment module that collects and fuses sensor data from multiple surroundings sensors to create a unified vehicle environment model, which is then used to generate control signals for actuating systems, eliminating the need for individual control units for each sensor and simplifying networking within the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driver assistance functions are distributed to different control devices with individual control units for each sensor, then each function can be independently controlled, but the device complexity and error susceptibility increase significantly
Solution Approach 1:
The patent merges multiple individual control units into a single control unit that processes sensor data from all environment sensors. This consolidation reduces the number of control units and networking complexity while maintaining the capability to provide multiple driver assistance functions, directly resolving the technical contradiction between adaptability and device complexity.
Solution Approach 2:
The control unit is designed with universal functionality to handle multiple driver assistance functions simultaneously. Instead of having dedicated control units for each function, a single multi-functional control unit processes sensor data and generates control signals for various actuating systems, thereby reducing overall system complexity while preserving versatility.
2Reliability
If individual control units are used for each sensor to form separate vehicle environment models, then each sensor can be independently processed, but costs and material requirements increase
Solution Approach 1:
The patent combines multiple individual control units into a single control unit that handles processing for all sensors. This reduces the quantity of control units and associated materials while maintaining reliable sensor data processing through centralized architecture, directly addressing the contradiction between reliability and quantity of materials.
3Measurement precision
If multiple separate vehicle environment models are generated by different control units, then each model can be optimized for specific functions, but the networking becomes more error-prone and complex
Solution Approach 1:
The patent merges the generation of multiple separate vehicle environment models into a single unified model created by one control unit. This eliminates the networking complexity and error susceptibility associated with multiple control units communicating, while maintaining measurement precision through comprehensive sensor data fusion within the unified control architecture.
