Vehicle Brake Control Architecture With Integrated Inertia Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle electric systems lack effective dynamic control solutions for automated driving scenarios, particularly in SAE Automation levels 2 and 3, where continuous driver attention is not required, and existing brake regulation systems do not adequately utilize sensor information for stabilization and improved driving dynamics.
Innovation Solution
An electric system for vehicles incorporating a steering angle sensor unit, at least one control module with an integrated inertia sensor, and an electronic braking system central control unit, where inertia sensors provide information on yaw rate, acceleration, and roll rates to facilitate dynamic control and stabilize the vehicle, enabling automated driving without continuous driver attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inertia sensors are integrated into control modules, then measurement precision and dynamic control capability are improved, but device complexity increases
Solution Approach 1:
The patent integrates inertia sensors directly into control modules, merging previously separate sensing and control functions into a unified structure. This integration improves measurement precision by capturing inertia information at the source while reducing signal transmission errors, and simultaneously optimizes system architecture by eliminating separate sensor mounting structures and wiring harnesses.
2Extent of automation
If multiple sensors are integrated into control modules, then automated driving capability is improved, but ease of operation deteriorates due to increased installation complexity
Solution Approach 1:
By integrating multiple sensors including inertia sensors directly into control modules, the patent creates pre-assembled functional units that combine sensing, processing, and control capabilities. This merging approach enhances automated driving capability through coordinated multi-sensor data while simplifying installation, as the integrated modules require fewer separate mounting operations and wiring connections compared to distributed sensor placement.
