Steering Wheel Warning for Slope Parking Wheel Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers may forget to turn their vehicle's wheels towards the curb when parking downhill, which can lead to accidents if the brake system fails, as this practice is only performed when parking downhill and not as a standard procedure.
Innovation Solution
A system mounted on the vehicle uses image recognition to determine the steering wheel's position and angular difference, outputting a warning when the vehicle is parked on a slope to remind the driver to adjust the wheels appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver manually turns the wheels toward the curb when parking downhill, then the vehicle is protected from rolling down in case of brake failure, but the driver may forget to perform this action since it is not a standard procedure
Solution Approach 1:
The system continuously monitors vehicle motion status and steering wheel position, then provides real-time feedback to the driver through warnings when the vehicle is parked on a slope with the steering wheel in an incorrect position. This feedback loop ensures the driver is reminded to properly position the wheels without requiring manual recall of the procedure.
Solution Approach 2:
The system automatically detects slope conditions and steering wheel position using sensors and image recognition, eliminating the need for the driver to manually assess these conditions. The system serves itself by monitoring its own state and providing appropriate warnings, reducing the cognitive burden on the driver.
2Measurement precision
If the system continuously monitors vehicle status and steering wheel position using image recognition and sensors, then accurate real-time warnings can be provided, but the device complexity increases
Solution Approach 1:
The system uses a multi-functional approach where a single processing unit handles multiple tasks: image recognition for steering wheel detection, sensor data processing for vehicle motion status, slope condition determination, and warning generation. This consolidates multiple functions into one unit, reducing overall system complexity while maintaining measurement precision.
Solution Approach 2:
The system introduces an intermediary processing unit that acts as a mediator between various sensors (image capturing unit, motion sensors) and the warning output mechanism. This intermediary consolidates data from multiple sources, processes it centrally, and coordinates the warning output, simplifying the integration of multiple components.

Function Achieved in This Case
The system effectively notifies the driver to turn the steering wheel correctly when parked on a slope, preventing unwanted vehicle movement and potential accidents by providing a real-time warning based on the vehicle's motion and angular position.
Implementation Method 1
determine a reference position of a steering wheel of the vehicle according to a motion status of the vehicle and a rotation status of the steering wheel of the vehicle with assistance of image recognition

AI summary
A method is provided for outputting a warning when a vehicle is parked on a slope. The method is to be implemented using a system that is mounted on the vehicle. The method includes steps of: determining a reference position of a steering wheel of the vehicle according to a motion status of the vehicle and a rotation status of the steering wheel with assistance of image recognition; obtaining a real-time angular difference between a current angular position of the steering wheel and the reference position; and when the vehicle meets a slope-parking condition, determining whether or not to output a warning related to operation of the steering wheel based on the real-time angular difference.
