Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency braking systems lack effective control over brake release after emergency braking, leading to potential collisions due to driver errors, as they rely on simple driver operations without sophisticated sensor-based control mechanisms.
Innovation Solution
An emergency braking system that utilizes sensors to detect the position of objects while a vehicle is reversing, dividing the detection area into multiple zones to control brake release based on the object's position, allowing for intentional brake release through user input or specific driving operations, using ultrasonic and camera sensors to determine the appropriate time and manner of brake release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the brake is released according to simple driver operation after emergency braking, then the ease of operation is improved, but the reliability deteriorates due to driver errors causing faulty brake release
Solution Approach 1:
The system automatically determines brake release timing by monitoring sensor data and detecting driver intentions, eliminating the need for manual brake release operations. The controller self-manages the brake release process based on detected driving conditions, thereby improving reliability while maintaining ease of operation.
Solution Approach 2:
The system continuously monitors sensor data including ultrasonic sensor readings, camera images, and driving operation signals to detect driver intentions. This feedback mechanism allows the controller to make informed decisions about brake release timing, preventing faulty release while requiring minimal driver input.
2Measurement precision
If the detecting area is divided into multiple areas for precise brake release control, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The detecting area is divided into multiple regions (first detecting area, second detecting area, third detecting area) based on distance from the vehicle. This segmentation allows the system to apply different brake release control strategies for different object positions, improving measurement precision while managing complexity through structured zonation.
Solution Approach 2:
Different brake release control methods are applied to different detecting areas. For example, automatic release is applied in the first detecting area where objects are farthest, while manual confirmation is required in closer areas. This local differentiation optimizes control precision without uniformly increasing system complexity.
